Nicholas Wolterstorff interprets and discusses the ethics of belief which Locke developed in the latter part of Book iv of his Essay Concerning Human Understanding. After lengthy discussions on the origin of ideas, the nature of language, and the nature of knowledge, Locke got around to arguing what he indicated in the opening Epistle to the R e a d e r to be his overarching aim: how we ought to govern our belief, especially (though by no means only) on matters of religion and morality. Professor Wolterstorff shows that w h a t above all placed this topic on Locke's agenda was the collapse, in his day, of a once-unified moral and religious tradition in E u r o p e into warring factions. Locke's epistemology was thus a culturally and socially engaged one; it was his response to the great cultural crisis of his day. Convinced also that of genuine knowledge we human beings have very little, Locke argued that instead of following tradition we ought to turn "to the things themselves" and let " R e a s o n be your g u i d e . " This view of Locke, in which centrality is given to the last book of the Essay, invites an interpretation of the origins of modern philosophy different from most of the current ones. Accordingly, after discussing Hume's powerful attack on Locke's recommended practice, Wolterstorff argues for Locke's originality and discusses his contribution to the " m o d e r n i t y " of post-sixteenth-century philosophy.

Philosophy as a discipline thus [sawj itself as the attempt to underwrite or debunk claims to knowledge made by science, morality, art, or religion. It [purported] to do this on the basis of its special understanding of the nature of knowledge and of mind. Philosophy can be foundational in respect to the rest of culture because culture is the assemblage of claims to knowledge, and philosophy adjudicates such claims. It can do so because it understands the foundations of knowledge, and it finds these foundations in a study of man-as-knower, of the "mental processes" or the "activity of representation" which make knowledge possible . . . Philosophy's central concern [was] to be a general theory of representation, a theory which will divide culture up into the areas which represent reality well, those which represent it less well, and those which do not represent it at all (despite their pretense of doing so). 1

proposition self-evident to the person, or a proposition which is an incorrigible report of a mental act or object of the person. W e called it (not very felicitously) "Reformed epistemology" because w c took it to be characteristic of the Reformed tradition of Christianity. M y earliest objections to classical foundationalism can be found in Reason within the Bounds of Religion (Grand Rapids, Eerdmans, 1 9 7 6 ) . T h e best statement of Reformed epistemology was given in the essays by Alston, Plantinga, and myself in Alvin Plantinga and Nicholas Wolterstorff (eds.), Faith and Rationality (Notre D a m e , University of Notre D a m e Press, 1 9 8 3 ) .

believed, it would plainly be impossible - supposing tradition alone lays down the ground of our duty - to find out w h a t that tradition is, or to pick out truth from among such a variety, because no ground can be assigned why one man of the old generation, rather than another maintaining quite the opposite, should be credited with the authority of tradition or be more worthy of trust; except it be that reason discovers a difference in the things themselves that are transmitted, and embraces one opinion while rejecting another, just because it detects more evidence recognizable by the light of nature for the one than for the other. Such a procedure, surely, is not the same as to believe in tradition, but is an attempt to form a considered opinion about things themselves; and this brings all the authority of tradition to naught. 2

T h e Essay was conceived primarily to aid them in their everyday lives, to guide them in the great practical concerns of religion, morality, politics, and law, and in normal intercourse" (p. 2 ) .

In thus interpreting Locke as responding to a crisis, I agree with J a m e s Tully, "Governing C o n d u c t , " in E d m u n d Lcites (ed.), Conscience and Casuistry in Early Modern Europe ( C a m b r i d g e , C a m b r i d g e University Press, 1 9 8 8 ) . T h e crisis to which Leites points was social as well as cultural; he calls the whole a "legitimation crisis." I entirely agree that in the totality of his work Locke was responding to a social, as well as to a cultural, crisis. I furthermore agree that the cultural crisis to which he was responding contributed to the social crisis; there was indeed a "legitimation crisis." But in my discussion I shall be focusing my attention almost entirely on Locke's response to the great cultural crisis threatening his society, that of intense partisanship in a situation of fractured tradition.

As already mentioned, skepticism also played a role in bringing about that cultural anxiety which Locke addressed. A full account of the contribution of the resurgence of skepticism to that anxiety, under the stimulus of the recovery of the ancient skeptical writings, would trace the interaction between "the problem of the criterion" posed by the skeptics, and the disputes by religious parties over "the rule of faith."

The Vision: Let Reason be Your Guide in
Believing
Faith is nothing but a firm assent of the mind: which if it be regulated, as is our duty, cannot be afforded to anything, but upon good reason; and so cannot be opposite to it. H e that believes, without having any reason for believing, m a y be in love with his own fancies; but neither seeks truth as he ought, nor pays the obedience due his maker, who would have him use those discerning faculties he has given him, to keep him out of mistake and errour. H e that does not this to the best of his power, however he sometimes lights on truth, is in the right but by chance; and I know not whether the luckiness of the accident will excuse the irregularity of his proceeding. T h i s at least is certain, that he must be accountable for whatever mistakes he runs into: whereas he that makes use of the light and faculties G o d has given him, and seeks sincerely to discover truth, by those helps and abilities he has, m a y have this satisfaction in doing his duty as a rational creature, that though he should miss truth, he will not miss the reward of it. F o r he governs his assent right, and places it as he should, who in any case or matter whatsoever, believes or disbelieves, according as reason directs him. H e that does otherwise, transgresses against his own light, and misuses those faculties, which were given him to no other end, but to search and follow the clearer evidence, and greater probability. (iv,xvii,24) H e r e is the p i c t u r e : G o d h a s e n d o w e d us w i t h v a r i o u s faculties for the f o r m a t i o n o f beliefs. B u t in c o n s t r u c t i n g us as G o d d i d , G o d h a d in m i n d n o t j u s t t h a t w e have beliefs b u t t h a t o u r beliefs be true; L o c k e n e v e r so m u c h as c o n s i d e r s the p o s s i b i l i t y t h a t G o d , in d e s i g n i n g us, m i g h t h a v e h a d in m i n d m o r e d e s i d e r a t a t h a n t r u t h for the beliefs p r o d u c e d b y o u r b e l i e f - f o r m i n g f a c u l t i e s .

T h e r e is, of course, nothing in this paragraph that Descartes would disagree with. In C h a p t e r 2 I shall argue, however, that the Cartesian project, within which these convictions find their place, is significantly different from the Lockian project. T h e significance of the shared convictions differs.

k n o w l e d g e is a species o f belief. K n o w l e d g e a n d b e l i e f r e p r e s e n t the exercise of f u n d a m e n t a l l y different faculties: T h u s the mind has two faculties, conversant about truth and falsehood. First, knowledge, whereby it certainly perceives, and is undoubtedly satisfied of the agreement or disagreement of any ideas. Secondly, judgement, which is the putting ideas together or separating them from one another in the mind, when their certain agreement or disagreement is not perceived, but presumed to be so. (iv,xiv,4) T h o u g h h e is u n e m p h a t i c a b o u t it, L o c k e d i d a s s u m e t h a t the p h e n o m e n o n of taking to be true t y p i c a l l y a c c o m p a n i e s k n o w l e d g e .

Sec especially the whole chapter on M a x i m s , Essay iv.vii. Here is just one example: " F o r that which makes the mind assent to such propositions, being nothing else but the perception il has of the agreement, or disagreement of its ideas . . . " (iv,vii,o,). Michael Ayers in Locke: Volume I: Epistemology (London and N e w Y o r k , R o u l l c d g c , 1 9 9 1 ) , Part 11, esp. chap. 1 3 , points out that whereas Descartes (and others) thought of propositions as entities which we can not only believe and affirm but also merely entertain, Locke's oflicial thought prevents him from saying this. F o r he thinks of us as composing propositions by putting "ideas" together in predicative fashion; and his official explanations imply that this combinatory act involves belief (assent), or at least judgment (affirmation). Y e t at various points in Book iv, Locke clearly allows for withholding belief (and affirmation) from some particular proposition. So how are we to interpret him? It appears to me that in practice Locke thought of the combinatory predicative act of composing a proposition as not necessarily involving belief or affirmation; one can, as it were, perform the act in the entertaining or withholding mode. T h a t is how I shall interpret him. But Locke himself never recognizes the issue. A s to the wavering character of Locke's distinctions between "belief," "assent," "judgment," "opinion," and so forth, see A y e r s , ibid., p. 3 1 2 , n. 1 3 .

T h e contrary whereof appears from the words which I have set down, out of chap. 30, where I deny only the simple ideas of secondary qualities to be representations; but do everywhere affirm, that the simple ideas of primary qualities are the images or representations of what does exist without us . . . the simple ideas of secondary qualities . . . are not representations or images of anything in bodies, but only effects of certain powers in bodies to produce them in us . . . [Nonetheless] we as certainly know and distinguish things by ideas, supposing them nothing but effects produced in us by these powers, as if they were representations.

" O n whether L o c k e held a representational theory of perception, see Reginald J a c k s o n , "Locke's Version of the Doctrine of Representative Perception" in C . B. Martin and D . M . Armstrong (eds.), Locke and Berkeley (Notre D a m e , University of Notre D a m e Press, 1 9 6 8 ) . In general, I go along with Ghappell and A y e r s (in the works just cited) in interpreting L o c k e as holding that ideas are mental objects; some commentators have argued that he regarded them instead as mental acts - specifically, acts of perceiving. See, for example, Douglas Greenlee, "Locke's Idea o f ' I d e a ' " (and the ensuing discussion), in I. C . Tipton (ed.), Locke on Human Understanding (Oxford, Oxford University Press, 1 9 7 7 ) ; and J o h n Y o l t o n , " L o c k e

I have argued above that such a passage as this should not be interpreted as saying that all ideas are mental representations, only that all mental representations are ideas; but it is entirely clear that this passage treats at least those ideas which are representational as mental objects.

things signified by them, do agree or disagree one with another. T h e joining or separating of signs here meant is what by another name, we call proposition" ( i v , v , 2 ) . It is presupposed by this definition that the ideas joined in a mental proposition always signify the entities whose agreement with each other makes the proposition true rather than, in some cases, the ideas put together in the mental proposition just being the ideas whose agreement makes the proposition true. Essentially the same formula is olfered at the end of §5 of the same chapter, the only dilference being that Locke speaks there of the signs as landing for, rather than signifying, the things. It is clear, however, that the formulation which accurately expresses Locke's thought is the one quoted in the text above. T h a t sometimes the very ideas that one perceives to agree are put together into a proposition is presupposed by the sentence opening §6 of chapter v : " E v e r y one's experience will satisfy him, that the mind, either by perceiving or supposing the agreement or disagreement of any of its ideas, does tacitly within itself put them into a kind of proposition affirmative or negative, which 1 have endeavoured to express by the terms putting together and separating" ( i v , v , 6 ) . In fiis discussion of these passages in Locke, Leibniz makes the correct point that if Locke regards himself as explaining affirmation and negation in terms of "putting together" and "separating" words or ideas, then it must be observed that not all w a y s of "putting together" yield affirmations and not all ways of "separating" yield negations; whereas if he regards affirmation and negation as merely a species of "putting together" and "separating," then nothing is said to explain the species. A b o u t the first of these possibilities, Leibniz says this: "a phrase, e.g. 'the wise man,' does not make a proposition; yet it involves a joining of two terms. Nor is negation the same as separation; for saying 'the man' and then after a pause uttering 'wise' is not making a denial." A b o u t the second possibility, Leibniz says this: "Agreement obtains between two eggs, disagreement between two enemies. W h a t w e are dealing with here is a quite special w a y of agreeing or disagreeing, and I do not think that your definition explains it" ( G . W . Leibniz, New Essays on Human Understanding [tr. and ed. P. R e m n a n t and J . Bennett ( C a m b r i d g e , C a m b r i d g e University Press, 1 9 8 1 ) ] , p. 3 9 6 ) .

Locke is responding to an objection which he formulates as follows: " I f it be true, that all knowledge lies only in the perception of the agreement or disagreement of our own ideas, the visions of an enthusiast, and the reasonings of a sober man, will be equally certain. 'Tis no matter how things are: so a man observe but the agreement of his own imaginations, and talk conformably, it is all truth, all certainty. Such castles in the air, will be as strong holds of truth, as the demonstrations of Euclid. T h a t an harpy is not a centaur, is by this w a y as certain knowledge, and as much a truth, as that a square is not a circle. But of what use is all this fine knowledge of men's own imaginations, to a man that enquires after the reality of things?" (iv,iv,2; cf. i v , v , 7 , where the point is made even more vividly - and at greater length).

Cf. iv,vi,i6": " T o conclude, general propositions, of what kind soever, arc then only capable of certainty, when the terms used in them, stand for such ideas, whose agreement or disagreement, as there expressed, is capable to be discovered by us. A n d we are then certain of their truth or falsehood, when we perceive the ideas the terms stand for, to agree or not agree, according as they are aflirmcd or denied one of another. W h e n c e we may take notice, that general certainty is never to be found but in our ideas. Whenever we go to seek it elsewhere in experiment, or observations without us, our knowledge goes not beyond particulars. "I'is the contemplation of our own abstract ideas, that alone is able to afford us general knowledge."

Cf. iv,vi,4: " E v e r y o n e finds in himself, that he knows the ideas he has; that he knows also, when any one is in his understanding . . . [ H ] e can never be in doubt, when any idea is in his mind, that it is there" (ibid.). "He knows each | idea] to be . . . in his mind, and not a w a y when it is there" (ibid.). Including the following famous passage, in which Locke speaks as if all propositions which can be known to be true are either analytically necessary or synthetically necessary - which, of course, excludes our knowledge that w e ourselves exist, or that something exists which is causing this present image of mine, or that w e have such-and-such ideas: " W e can know then

He himself remarks that there is "no necessary connection of real existence, with any idea a man hath in his memory, nor of any other existence but that of G o d " ( i v , x i , i ) . T h u s the passage above about knowledge of two sorts of propositions has to be understood in the light of this other one which is also about two sorts of propositions which can be known: "there are two sorts of propositions. 1 . T h e r e is one sort of propositions concerning the existence of any thing answerable to such an idea: as having the idea of an elephant, phoenix, motion, or an angel, in my mind, the first and natural enquiry is, whether such a thing does any where exist? A n d this knowledge is only of particulars. N o existence of any thing without us, but only of G o d , can certainly be known farther than our senses inform us. 2 . T h e r e is another sort of propositions, wherein is expressed the agreement, or disagreement of our abstract ideas, and their dependence one on another. Such propositions m a y be universal and certain" ( i v , x i , i 3 ) .

Locke's insistence that we can perceive agreements and disagreements among ideas which are not themselves entirely clear and distinct is crucial to the analysis he offers of knowledge of self-existence: "in some cases we may have certainty about obscure ideas; e.g. by the clear idea of thinking in me, I find the agreement of the clear idea of existence, and the obscure idea of a substance in me, because I perceive the necessary idea of thinking, and the relative idea of a support; which support, without having any clear and distinct idea of what it is, beyond this relative one of a support, I call substance" (Works 1 1 1 , 4 2 ) .

Cf. this passage in the Second Letter to Stillingfleet: "where I examine, whether the knowledge we have of mathematical truths, be the knowledge of things as really existing: there 1 say (and 1 think I have proved) that it is, though it consists in the perception of the agreement or disagreement of ideas, that are only in the mind; because it takes in all those things, really existing, which answer those ideas. U p o n which grounds it was, that I there affirmed moral knowledge also capable of certainty. A n d pray, my lord, what other w a y can your lordship proceed, in any demonstration you would make, about any other thing but figures and numbers, but the same that you do in demonstrations about figures and numbers? If you would demonstrate anything concerning man or murder, must you not first settle in your mind the idea or notion you have of that animal or that action, and then show what you would demonstrate necessarily to belong to that idea in your mind, and to those things existing only as they correspond with, and answer that idea in your mind? H o w else you can make any general proposition, that shall contain the knowledge of things as really existing, I that am ignorant shall be glad to know?" (Works 1 1 1 , 4 0 5 - 6 ) .

I . Aaron comes in his 'John Locke (Oxford, Clarendon Press, 1 9 7 1 ) : "Locke left the two theories of knowledge standing side by side with little effort to make them consistent. K n o w l e d g e is the perception of relations between ideas: but we also know particular existences directly, and in this case knowledge is not the perception of relations between ideas" (p. 2 4 1 ) . " W e m a y conclude then that the fact of existential knowledge has caused Locke to introduce thoroughgoing alterations in his account of knowledge. H e opens Book iv of the Essay with a theory of knowledge applicable, as it proves, merely to knowledge of relations between abstract ideas, a universal, hypothetical, and highly abstract knowledge, best typified in mathematics. Another theory became necessary for knowledge of particular existences. Consequently, Locke's whole account of knowledge is far from consistent, for he does not even try to remove this dualism or to relate the two theories" (pp. 2 4 6 - 7 ) . Locke's account of knowledge is indeed not consistent, as we shall see shortly; but there is no inconsistency at the point where A a r o n purports to see inconsistency. T h e r e is no second theory of knowledge in Locke which is meant for knowledge of particular existences.

I doubt not but if we could discover the figure, size, texture, and motion of the minute constituent parts of any two bodies, we should know without trial several of their operations one upon another, as we do now the properties of a square, or a triangle. Did we know the mechanical affections of the particles of rhubarb, hemlock, opium, and a man, as a w a t c h m a k e r does those of a watch, whereby it performs its operations, and of a file which by rubbing on them will alter the figure of any of the wheels, we should be able to tell before hand, that rhubarb will purge, hemlock kill, and opium make a man sleep; as well as a watchmaker can, that a little piece of paper laid on the balance, will keep the watch from going, till it be removed; or that some small part of it, being rubbed by a file, the machine would quite lose its motion, and the watch go no more. T h e dissolving of silver in a q u a fortis, and gold in a q u a regia, and not vice versa, would be then, perhaps, no more difficult to know, than it is to a smith to understand, why the turning of one key will open a lock, and not the turning of another.

I think the real essences of things arc not so much founded on, as that they are the very real constitution of things" (First Letter to Stillingfleet; Works 1 1 1 , 8 2 - 3 ) .

T h o u g h the familiar use of things about us, take off our wonder; yet it cures not our ignorance. W h e n w e come to e x a m i n e the stone we tread on; or the iron, w e daily handle, w e presently find, w e know not their make; and can give no reason, of the different qualities we find in them. ' T i s evident the internal constitution, whereon their properties depend, is unknown to us. For to go no farther than the grossest and most obvious we can imagine amongst them, what is that texture of parts, that real essence, that makes lead, and antimony fusible; wood, and stones not? W h a t makes lead, and iron malleable; antimony, and stones not? A n d yet how infinitely these come short, of the fine contrivances, and unconceivable real essences of plants and animals, every one knows. T h e w o r k m a n s h i p of the all-wise, and powerful G o d , in the great fabric of the universe, and every part thereof, farther exceeds the capacity and comprehension of the most inquisitive and
physics would still be only "ra.v a priori, as certain and demonstrative, as interpreted geometry and applied mechanics a r e " ( J . L . M a c k i e , Problems from Locke [Oxford, Clarendon Press, 1 9 7 6 ] , p. 1 0 2 ) . Though that is a plausible interpretation of the passage quoted above, from i v , h i , 2 5 , it's hard to see w h a t , in his thoughts about essence, would have led Locke to such caution. A n d in any ease, that interpretation clearly does not (it with the following passage: " H a d we such ideas of substances, as to know w h a t real constitutions produce those sensible qualities we find in them, and how those qualities (lowed from thence, we could, by the specific ideas of their real essences in our own minds, more certainly find out their properties, and discover what qualities they had, or had not, than we can now by our senses: and to know the properties of gold, it would be no more necessary, that gold should exist, and that we should make experiments upon it, than it is necessary for the knowing the properties of a triangle, that a triangle should exist in any matter, the idea in our minds would serve for the one, as well as the other" (iv,vi,i 1 ) . 2 8
'There is a dispute in the literature as to w h a t L o c k e meant by God's "arbitrary determination" in this passage and in others like it (for the dispute, see M c C a n n , "Locke's Philosophy of B o d y " ) . I think it most unlikely that L o c k e was of the view that certain of the properties and operations of bodies have no necessary connection to their essences, and that G o d just arbitrarily determines the connections. I think it much more likely to have been Locke's view that "all their properties and operations flow from" their essences ( m , x v i , 2 3 ) ; < but that it was a matter of arbitrary determination on God's part which essences He would instantiate. Since we don't grasp the essences of material bodies, and since we certainly don't
' ' grasp how the properties and operations of bodies "flow from" their essences, and since, even if we did grasp those two things, it would still not be a matter acknowledge on our part which essences G o d instantiated, knowledge of nature is, for those three reasons, unavailable to us.

the want oj ideas we are capable of. As the want of ideas which our faculties are not able to give us, shuts us wholly from those views of things, which 'tis reasonable to think other beings, perfecter than we, h a v e , of which we know nothing; so the want of ideas, I now speak of, keeps us in ignorance of things, we conceive capable of being known to us. Bulk, figure, and motion we have ideas of. But though we are not without ideas of these primary qualities of bodies in general, yet not knowing what is the particular bulk, figure, and motion of the greatest part of the bodies of the universe, we are ignorant of the several powers, efficacies, and w a y s of operation whereby the effects, which we daily see, are produced.

H a d w e senses acute enough to discern the minute particles of bodies, and the real constitution on which their sensible qualities depend, I doubt not but they would produce quite different ideas in us; and that which is now the yellow colour of gold, would then disappear, and instead of it we should see an admirable texture of parts of a certain size and figure. This microscopes plainly discover to us: for w h a t to our naked eyes produces a certain colour, is by thus augmenting the acuteness of our senses, discovered to be quite a different thing; and altering, as it were, the proportion of the bulk of the minute parts of a coloured object to our usual sight, produces different ideas, from w h a t it did before . . . Blood to the naked eye appears all red; but by a good microscope, wherein its lesser parts appear, shows only some few globules of red, swimming in a pellucid liquor; and how these red globules would appear, if glasses would be found, that yet could magnify them iooo, or ioooo times more, is uncertain.

° T h e best discussion of this matter is Laurens L a u d a n , " T h e N a t u r e and Sources of Locke's Views on Hypotheses," in 1. C . T i p t o n (ed.), Locke tin Human Understanding (Oxford, Oxford University Press, 1 9 7 7 ) . " CX iv,xvi, 12: "This sort of probability, which is the best conduct of rational experiments, and the rise of hypothesis, has also its use and influence; and a w a r y reasoning from analogy leads us often into the discovery of (ruths, and useful productions, which would otherwise lie concealed." "It will, 110 doubt, be presently objected, Is not this an universal certain proposition, All gold is malleable? T o which I answer, it is a very certain proposition, if malleablcness be a part of the complex idea the word gold stands for. But then here is nothing affirmed of gold, but that that sound stands for an idea in which malleablcness is contained: and such a sort of truth and certainty as this, it is to say a centaur is four-footed. But if malleableness makes not a part of the specific essence the name gold stands for, 'lis plain, all gold is malleable, is not a certain proposition. Because let the complex idea of gold, be made up of which soever of its other qualities you please, malleableness will not appear to depend on that complex idea; nor follow from a n y simple one contained in it. The connection that malleableness has (if it has any) with those other qualities, being only by the intervention of the real constitution of its insensible parts, which, since we know not, 'tis impossible we should perceive that connection, unless we could discover that which ties them together. T h e more, indeed, of those co-existing qualities we unite into one complex idea, under one name, the more precise and determinate we make the signification of that word; but yet never make it thereby more capable of universal certainty, in respect of other qualities, not contained in our complex idea; since we perceive not their connection, or dependence one on another; being ignorant

both of that real constitution in which they are all founded; and also how they flow from it" (iv,vi,9-io). T h o u g h Locke, in a fascinating passage, contends that we use many of our general terms with the intention that they function like that: "there is scarce anybody in the use of these words but often supposes each of those names to stand for a thing having the real essence" (m,x, 1 8 ; see § § 1 7 — 1 9 ) . There is an excellent discussion of Locke's distinction between real essence and nominal essence in J . L . Mackie, Problems from Locke, pp. 8 5 - 1 0 0 .

Leibniz, in .New Essays, p. 1 3 4 , says thai he "would prefer lo distinguish between perception and bring aware. F o r instance, a perception of light or colour of which we are a w a r e is made up of many minute perceptions of which we arc unaware; and a noise which we perceive but do not attend to is brought within reach of our awareness by a tiny increase or addition. If the previous noise had no effect on the soul, this minute addition would have none either, nor would the total." Locke interprets the phenomena here differently. Though awareness is not, on his view, a condition of sensory stimulation, it is a condition of perception; and in turn, it appears to be his view thai there are no unperceived ideas: " A sufficient impulse there m a y be on the organ; but it not reaching the observation of the mind, there follows no perception . . . W a n t of sensation in this case, is not through any defect in the organ, or that the man's ears are less affected, than at other times, when he does hear: but that which uses to produce the idea, though conveyed in by the usual organ, not being taken notice of in the understanding, and so imprinting no idea on the mind, there follows no sensation. S o that wherever there is sense, or perception, there some idea is actually produced, and present in the understanding" (n,ix,4).

Cf. this passage from Locke's near contemporary, J o h n Wilkins: "It behooves everyone in the search for truth, always to preserve a philosophical liberty, not to be cnslav'd to the opinion of any man as to think whatever he says to be infallible. W e must labour to find out what things are in themselves, by our own experience, and a thorough examination of their natures, not what another says of them." Quoted by Barbara J . Shapiro, Probability and Certainly in Seventeenth-Century England (Princeton. Princeton University Press, 1 9 8 3 ) , p. 64. The following passage from Locke, Essay i , i v , 2 3 , makes the point by referring (rather smugly) to his own practice: "This I am certain, I have not made it my business, either to quit, or follow any authority in the ensuing discourse: truth has been my only aim; and wherever that has appeared to lead, m y thoughts have impartially followed, without minding, whether the footsteps of any other lay that w a y , or not. Not that I want a due respect to other men's opinions; but after all, the greatest reverence is due to truth; and, I hope, it will not be thought arrogance to say, that, perhaps, we should make greater progress in the discovery of rational and contemplative knowledge, if we sought it in the fountain, in the consideration of things themselves and made use rather ofour own thoughts than other men's to find it. For, 1 think, we m a y as rationally hope to see with other men's eyes, as to know by other men's understandings."

This then accounts tor the fact that in his Second Letter to Slillingflcct, Locke says that all knowledge (and certainty) require self-evident propositions: "that there is any knowledge, without self-evident propositions, I am . . . far from denying" (Works 111,371)); " I make sell-evident propositions necessary to certainty, and found all certainty only in them" (ibid., 4 2 1 ) . T h e r e are a few passages in which it would appear that Locke is thinking of "perception" as immediate, and of propositions as self-evident, and holding that immediate "perception" of facts is the ground of assent to self-evident propositions: " O f such agreement, or disagreement as this, the mind has an immediate perception but in very few of them. A n d therefore in this sort, we have but very little intuitive knowledge: nor are there to be found very manypropositions that are self-evident" (iv,vii,5). But he is not consistent on this. Leibniz has a very interesting discussion of intuition in New Essays, pp. 3 6 1 - 7 , and 4 3 4 . He says that truths known by intuition are either "truths of reason" or "truths of fact." W h a t they have in common, he says, is that "we cannot prove them by anything more certain" (p. 3 6 7 ) . A n d he adds that "the immediate awareness of our existence and of our thoughts provides us with the first a posteriori truths or truths of fact, i.e., the first experiences; while identical propositions embody the first a priori truths or truths of reason, i.e., the first illuminations. Neither kind admits of proof, and each can be called 'immediate' - the former

T o make his point yet more clear, L o c k e offers an interesting analogy: "there is no object which the eye sees, that can be said to be perfectly obscure, for then it would not be seen at all; nor perfectly confused, for then it could not be distinguished from any other, no not from a clearer. F o r example, one sees in the dusk something of that shape and size, that a man in that degree of light and distance would appear. This is not so obscure, that he sees nothing; nor so confused, that he cannot distinguish it from a steeple or a star; but is so obscure, that he cannot, though it be a statue, distinguish it from a man; and therefore in regard of a man, it can produce no clear and distinct knowledge: but yet as obscure and confused an idea as it is, this hinders not but that there may many propositions be made concerning it, as particularly that it exists, of the truth of which we may be certain'' (Works, 1 1 1 , 2 4 2 ) .

Rather formidable difficulties will confront anyone who tries to work out this line of thought; for example: H o w are modes of belief-formation and modes of belief-sustenance to be individuated? H o w do we tell to which mode to assign a given believing? A n d what is reliability? E x a c t l y such difficulties have been confronted and dealt with by those who have developed reliability theories of justification and of knowledge.

A man is said to know any proposition, which having been once laid before his thoughts, he evidently perceived the agreement, or disagreement of the ideas whereof it consists; and so lodged it in his memory, that whenever that proposition comes again to be reflected on, he, without doubt or hesitation, embraces the right side, assents to, and is certain of the truth of it. This, I think, one m a y call habitual knowledge: A n d thus a man m a y be said to know all those truths, which are lodged in his memory, by a foregoing clear and full perception, whereof the mind is assured past doubt, as often as it has occasion to reflect on them. F o r our finite understanding being able to think, clearly and distinctly, but on one thing at once, if men had no knowledge of a n y more than what they actually thought on, they would all be very ignorant: A n d he that knew most, would know but one truth, that being all he was able to think on at one time.

If I am right in my contention that w h a t Locke has in mind by sensitive knowledge and by knowledge of one's own existence also prove, on close scrutiny, to be cases of inferential knowledge, then even this premise will not always be available.

Stillingfleet already maintained, against Locke, that memory knowledge is not a case of "perceiving" agreements or disagreements among ideas. Locke's reply deletes ail the subtleties of his discussion in the Essay: " T h e third sort of propositions that your lordship excludes are those whose certainty we know by remembrance: but in these two [kinds of memory?] the agreement or disagreement of the ideas contained in them is perceived; not always indeed, as it was at first, by an actual view of the connection of all the intermediate ideas, whereby the agreement or disagreement of those in the proposition was at first perceived; but by other intermediate ideas, that show the agreement or disagreement of the ideas contained in the proposition, whose certainty w e remember" (Works 1 1 1 , 2 3 4 ) . Locke then repeats, with only very minor changes, the argument from the Essay which, he says, led him to the view that if one knowingly remembers having demonstrated P, one might genuinely know (i.e., "perceive") P even though one has forgotten the proof.

T h e r e is one passage in his Second Letter to Stillinglleet in which Locke appears to say, quite aggressively, that this is the full extent of our sensitive knowledge: " N o w the two ideas, that in this case are perceived to agree, and do thereby produce knowledge, are the idea of actual sensation (which is an action whereof I have a clear and distinct idea) and the idea of actual existence of something without me that causes that sensation. A n d what other certainty your lordship has by your senses of the existing of anything without you, but the perceived connection of those two ideas, I would gladly know" [Works 111,360). But there are other passages in which he clearly indicates that we can know something about the primary qualities of that which is causing our sensation - though what exactly that is, is not clear. Clearly it was his thought that one can know that something with some primary quality or other is causing one's sensation: "as to the existence of bodily substances, 1 know by my senses that something extended, and solid, and figured does exist; for my senses are the utmost evidence and certainty I have of the existence of extended, solid, figured things. These modes being then known to exist by our senses, the existence of them (which I cannot conceive can subsist without something to support them) makes me see the connection of those ideas with a support, or, as it is called, a subject of inhesion, and so consequently the connection of that support (which cannot be nothing) with existence. A n d thus I come by a certainty of the existence of that something which is a support of those sensible modes" (ibid., 2 9 ) . But in another passage he quite clearly indicates that we can know more than this - that we can know, to some extent, what are the primary qualities of the object causing our sensation: " m a y I not be certain that a ball of ivory that lies before my eyes is not square? A n d is it not my sense of seeing, that makes me perceive the disagreement of that square figure to that round matter, which are the ideas expressed in that proposition?" (ibid., 2 3 2 ) .

A n d if our dreamer pleases to try, whether the glowing heat of a glass furnace, be barely a wandering imagination in a drowsy man's fancy, by putting his hand into it, he m a y perhaps be wakened into a certainty greater than he could wish, that it is something more than bare imagination. So that this evidence is as great, as we can desire, being as certain to us, as our pleasure or pain . . . beyond which we h a v e no concernment, either of knowledge or being.

In this case the mind is fain to find out some other angles, to which the three angles of a triangle have an equality; and finding those equal to two right ones, comes to know their equality to two right ones. Those intervening ideas, which serve to shew the agreement of any two others, are called proofs; and where the agreement or disagreement is by this means plainly and clearly perceived, it is called demonstration, it being shewn to the understanding, and the mind made see that it is so. (iv,ii,2-3) I n the c a s e o f r e l a t i v e l y s h o r t proofs, it seems p l a u s i b l e to s a y t h a t w e c o m e to see the c o n n e c t i o n o f the i d e a s in the c o n c l u s i o n b y w a y o f s e e i n g their c o n n e c t i o n to o t h e r , m e d i a t i n g , i d e a s .

disagreement of the two ideas under examination . . . is found. This intuitive perception of the agreement or disagreement of the intermediate ideas, in each step and progression of the demonstration, must also be carried exactly in the mind, and a man must be sure that no part is left out; which because in long deductions, and the use of m a n y proofs, the memory does not always so readily and exactly retain: therefore it comes to pass, that this is more imperfect than intuitive knowledge, and men embrace often falsehoods for demonstrations.

T h i s knowledge by intervening proofs, though it be certain, yet the evidence of it is not altogether so clear and bright, nor the assent so ready, as in intuitive knowledge. For though in demonstration, the mind does at least perceive the agreement or disagreement of the ideas it considers; yet 'tis not without pains and attention: T h e r e must be more than one transient view to find it. A steady application and pursuit is required to this discovery: and there must be a progression by steps and degrees.

Concerning
J a m e s T u l l y , in "Governing Conduct," argues that Locke's epistemology must be seen as the repudiation of what he, Tully, calls "the dispositional account of assent." He cites some passages from Anti-Scepticism by Henry L e e , one of Locke's opponents, in support of this thesis. I do not find it at all clear, however, what this "dispositional account" is supposed to be. Tully's explanation runs thus: " A person assents to a proposition because he or she is naturally inclined towards truth and goodness, just as a stone naturally tends to its natural home, the earth. A s in all forms of teleological explanation, the action, assent, is explained by its natural tendency to a certain result or end, true beliefs" (pp. 1 8 - 1 9 ) . f^ w h a t does such a view actually come to? Presumably it is meant to be compatible with the obvious fact that we assent to many propositions because of the workings of our perceptual capacities, to many others because of the workings of memory, etc. Is it then the thesis that our indigenous belief-forming dispositions are generally reliable? If so, Locke certainly does not disagree. He holds that we have a capacity for "perception" which gives us direct awareness of certain facts. A n d more generally, he held that "we fail [our faculties] a great deal more than they fail us" (Conduct, §34; Works 1 1 , 3 8 0 ) . ut
T u l l y remarks that "If the mind were not disposed in some w a y to the truth or the good, •3 then it must be indifferent, and so all our knowledge is the product of custom and education" (p. 2 4 ) . Accordingly he says a couple of times over that, on Locke's view, beliefs are all the

result of custom or education (pp. 2 1 , 2 2 ) . But this is just mistaken. Not only does L o c k e think that we possess indigenous belief-forming dispositions which get educated (tutored, schooled); T u l l y entirely overlooks the fundamental role of "perception" in Locke's thought. Locke is not H u m e born out of season! Furthermore, Locke never speaks of the mind as indifferent; what he says, rather, is that we must practice indijferency - by which he means that, in the governance of our belief-forming dispositions, we must concern ourselves only with the truth and falsity of the propositions believed.

O n this fundamental point m y interpretation differs from a great many commentators - for example, from, to cite one of the most recent, Peter Schouls in his Reasoned Freedom: John Locke and Enlightenment (Ithaca, Cornell University Press, 1 9 9 2 ) . Schouls throughout adopts a universalizing interpretation of Locke, even though he recognizes that the procedure Locke recommends takes time and that, in Locke's view, not everybody has the time or should take it.

T o be indifferent which of two opinions is true, is the right temper of the mind that preserves it from being imposed on, and disposes it to examine with that indifferency, till it has done its best to find the truth, and this is the only direct and safe w a y to it."

B u t the d e m a n d for u n i v e r s a l j u s t i f i c a t i o n problems, says Albert:

insuperable
if one demands a justification for everything, one must also d e m a n d a justification for the knowledge to which one has referred back the views initially requiring foundation. This leads to a situation with three alternatives, all of which a p p e a r unacceptable: in other words, to a trilemma which, in view of the analogy existing between our problem and one which that celebrated and mendacious baron once had to solve, I should like to call the Miinchhausen trilemma. For, obviously, one must choose here between 1. an infinite regress, which seems to arise from the necessity to go further and further back in the search for foundations, and which, since it is in practice impossible, affords no secure basis; 2. a logical circle in the deduction, which arises because, in the process ofjustification, statements are used which were characterized before as in need of foundation, so that they can provide no secure basis; and, finally, 3. the breaking-off of the process at a particular point, which, admittedly, can always be done in principle, but involves an arbitrary suspension of the principle of sufficient justification, (p. 18) A l b e r t g o e s o n to a r g u e , as he a l r e a d y i n t i m a t e s in his s t a t e m e n t o f these o p t i o n s , t h a t e a c h o f these is u n a c c e p t a b l e .

E v e r y one knows what his proper business is, and what, according to the character he makes of himself, the world may justly expect of htm; and to answer that, he will find he will have time and opportunity enough to furnish himself, if he will not deprive himself, by a narrowness of spirit, of those helps that are at hand" (Conduct § 3 ; Works 1 1 , 3 3 0 ) .

In this state are the greatest part of mankind, who are given up to labour, and enslaved to the necessity of their mean condition; whose lives are worn out, only in the provisions for living.

S o that a great part of mankind are, by the natural and unalterable state of things in this world, and the constitution of humane affairs, unavoidably given over to invincible ignorance of those proofs, on which others build, and which are necessary to establish those opinions: the greatest part of men, having much to do to get the means of living, are not in a condition to look after those of learned and laborious enquiries.

A s 10 religious matters, this is what Locke says: "Besides his particular calling for the support of this life, everyone has a concern in a future life, which he is hound to look after. This engages his thoughts in religion; and here it mightily lies upon him to understand and reason right. M e n , therefore, cannot he excused from understanding the words, and framing the general notions relating to religion, right. The one day of seven, besides other days of rest, allows in the Christian world time enough for this (had they no other idle hours) if they would but make use of these vacancies from their daily labour, and apply themselves to an improvement of knowledge with as much diligence as they often do to a great many other things that arc useless" (Conduct, §8; Works 1 1 , 3 4 2 ) . See also Conduct, § 2 3 ; Works 1 1 , 3 6 0 . A similar point concerning moral matters is made in the following section of Conduct, and concerning the immediately practical matters that concern a person, at the end of the preceding section. Furthermore, Locke was convinced that only the person himself or herself is in the position

In this, whether and how far any one is faulty, must be left to the Searcher of hearts, the great and righteous J u d g e of all men, w h o knows all their circumstances, all the powers and workings of their minds; where it is they sincerely follow, and by w h a t default they at any time miss truth: and he, w e are sure, will j u d g e uprightly" (Third Letter for Toleration; Works v',299).

when testimonies contradict common experience, and the reports of history and witnesses clash, with the ordinary course of nature, or with one another; there it is, where diligence, attention, and exactness is required, to form a right judgment, and to proportion the assent to the different evidence and probability of the thing; which rises and falls, according as those two foundations of credibility, viz- common observation in like cases, and particular testimonies in that particular instance, favour or contradict it. These are liable to so great variety of contrary observations, circumstances, reports, different qualifications, tempers, designs, oversights, etc. of the reporters, that 'tis impossible to reduce to precise rules, the various degrees wherein men give their assent.

T h i s lasl passage is used by Ernan M c M u l l i n (as it was by L a u d a n , " T h e Nature and Sources") to support his contention that Locke had some inkling of the place of the hypothctico-dcductive (retroductivc) method in science: "Conceptions of Science in the Scientific Revolution," in David D . Lindberg and Robert W . W e s t m a n (eds.), Reappraisals of Ike Scientific Revolution ( C a m b r i d g e , C a m b r i d g e University Press), pp. 7 5 - 6 . M c M u l l i n observes that Locke proved more prescient on the role of the hypothctico-dcductive method than in his suggestion that we are to form hypotheses concerning imperceptible entities and processes on analogy to perceptible ones. M c M u l l i n ' s discussion also makes clear that Locke (along, perhaps, with Huygens) was the first significant thinker to see clearly that the new natural philosophy did not satisfy the ideals of the old scientia. E v e r y o n e else was trying to squeeze the new into the old, arguing that the new really did yield certainty. Not Locke.

N o w that we have all three principles before us, it is clear that contemporary Bayesian accounts of rationality bear a fascinating relationship to Locke's account of what I have called "alethic obligation." Both make crucial use of the concept of probability and the concept of levels of confidence. W h a t is decisive in making Locke's theory come out different is his foundationalism; everything is to rest on propositions that we see to be true. O u r contemporary Bayesians are coherentists.

There are very few lovers of truth for truths sake . . . H o w a man m a y know whether he be so in earnest is worth inquiry: and I think there is this one unerring mark of it, viz., the not entertaining any proposition with greater assurance than the proofs it is built upon will warrant. Whoever goes beyond this measure of assent, 'tis plain receives not truth in the love of it; loves not truth for truths sake, but for some other bye end. For the evidence that any proposition is true (except such as are self-evident), lying only in the proofs a man has of it, whatsoever degrees of assent he affords it beyond the degrees of that evidence, 'tis plain all that surplusage of assurance is owing to some other affection, and not to the love of truth. ( i v , x i x , i ) T h e a r g u m e n t lacks cogency. L o c k e assumes that w e are obligated to be " l o v e r s o f t r u t h for t r u t h ' s s a k e " ; a n d he a p p a r e n t l y takes it a s s e l f - e v i d e n t t h a t those w h o d o l o v e t r u t h for t r u t h ' s s a k e w i l l try to p r o p o r t i o n t h e i r l e v e l o f c o n f i d e n c e in a p r o p o s i t i o n to its p r o b a b i l i t y 6 7

Quoted in van L c e u w c n , The Problem of Certainty, pp. 8 3 - 4 . C o m p a r e this passage from Sir Geoffrey Gilbert, writing early in the next century, and making reference to Locke: "There are several degrees from perfect certainty and demonstration quite down to improbability and unlikencss, even to the confines of impossibility; and there are several acts of the mind proportioned to these degrees of evidence, which may be called degrees of assent, from full assurance and confidence, quite down to conjecture, doubt, distrust and disbelief. N o w what is to be done in all trials of right, is to range all matters in the scale of probability, so as to lay most weight where the cause ought to preponderate, and thereby to make the most exact discernment that can be, in relation to the right." Quoted in Shapiro, Probability and Certainty, pp. 1 8 1 - 2 .

Some time ago Alvin Plantinga published a now well-known article in which he charged classical foundationalists with self-referential incoherence: T h e i r holding of the criterion of classical foundationalism does not satisfy the criterion they hold ("Reason and Belief in G o d , " in Plantinga and Wolterstorff (eds.), Faith and Rationality [Notre D a m e , Notre D a m e University Press, 1983I). W a s Locke in this w a y guilty of self-referential incoherence? O n e of the w a y s in which classical foundationalisms differ from each other is this: T h e y differ with respect to the sorts of beliefs to which the criterion in question is meant to apply. N o t all are universalistic; and in particular, some are such that the belief that that version of classical foundationalism is true does not belong to the sorts of beliefs to which the criterion is meant to apply. For those foundationalisms, the fact that the holding of the criterion does not satisfy the criterion is not a mark of incoherence. It should also be noticed that even though self-referential incoherence is present when one's holding of a classical foundationalist criterion for the presence of some epistemic merit falls within the intended scope of the criterion but does not satisfy the criterion, nonetheless it does not follow that one's holding of the criterion does not possess that merit. For by the correct criterion, whatever that m a y be, one might be holding the mistaken criterion for the possession of the merit in such a w a y that one's belief possesses that merit. S o once again: W a s Locke self-referentially incoherent in espousing his foundationalist proposal for doing one's best? Well, does it follow from what L o c k e says that the criterion is to apply to epistemology? T h e principal issue is whether those who choose to engage in epistemology are obligated therein to try seriously to do their best. Almost certainly Locke thought so. O f course, he may have been mistaken about that; if so, no incoherence. But let us suppose that he was right about that. T h e n the question of self-referential incoherence is relevant. W h y did Locke bold his rules? S o far as I can tell, apart from the weak argument discussed above, because he thought it was self-evident for him that one does one's best if and only if one follows these rules. Given that, does he exhibit self-referential incoherence? Y e s and N o . Locke's conviction that one does one's best if and only if one satisfies his rules was not itself arrived at by following these rules. Locke's holding of the rules would satisfy the rules if they were self-evident to him -- and only if they were, since he does nothing at all satisfactory by w a y of offering evidence for them. But they were not self-evident for him, since, as we shall see later, they are mistaken; following the rules is not always doing one's best. Hence Locke's embrace of his rules for doing one's best does not itself satisfy the rules. ( O f course, since the rules are mistaken, he m a y nonetheless have done his best in embracing the rules!) But Locke does not only offer a highly general criterion for doing one's best. H e also has a thesis concerning obligation: F o r each of us there are matters concerning which we are obligated to try seriously to do our best to proportion our level of confidence in a proposition to its probability. A n d the fact that Locke's holding of his criterion for doing his best does not satisfy his criterion does not imply that his holding of the criterion was not the result of his

A s w e leave this topic of Locke's rules for the g o v e r n a n c e of belief (assent), let me summarize: W h e n the truth or falsehood of some proposition is of m a x i m a l concernment to one, so that one is obligated to try to do one's epistemic best t o w a r d that proposition, the first thing to do is to collect satisfactory evidence concerning the truth or falsehood of the proposition. T h a t done, one must reflect carefully on the probability of the proposition on that evidence. A n d finally, one is to proportion one's level of confidence in the proposition to its probability on one's (satisfactory) evidence. T o accomplish all this, it is important that one be concerned solely with determining whether P is true or false, entirely "indifferent" to a n y other value that believing or disbelieving P might h a v e for one. H e r e is one of Locke's o w n summaries of the whole process: In these two things, viz., an equal indifferency for all truth, I mean the receiving it in the love of it as truth, but not loving it for any other reason before we know it to be true; and in the examination of our principles, and not receiving any for such, nor building on them, until we are fully convinced, as rational creatures, of their solidity, truth, and certainty, consists that freedom of the understanding which is necessary to a rational creature, and without which it is not truly an understanding. It is conceit, fancy, extravagance, anything rather than understanding, if it must be under the constraint of receiving and holding opinions by the authority of anything but their own, not fancied, but perceived evidence. (Conduct, § I Q ; Works 11,347-8) T o this w e m a y add a passage already cited: Probability wanting that intuitive evidence, which infallibly determines the understanding, and produces certain knowledge, the mind, if it will proceed rationally, ought to e x a m i n e all the grounds of probability, and see how they make more or less, for or against any probable proposition, before it assents to or dissents from it, and upon a due balancing the whole, reject, or receive it, with a more or less firm assent, proportionably to the preponderancy of the greater grounds of probability on one side or the other. (iv,xv,5) 71
A picture of intense self-discipline comes to m i n d . M a x W e b e r thought that the most striking e x a m p l e of discipline in the modern having tried seriously to follow the eriterion. A n d in fact, I see no reason to think that Locke's holding of the criterion was not the result of his having tried seriously to apply the criterion. T h o u g h his espousal of the criterion is not in fact the result of his doing what the criterion specifies as doing one's best, nonetheless it appears to be the result of his having tried seriously to do what the criterion specifies as doing one's best. A n d that's w h a t Locke's account of doxastic obligation, coupled with his criterion for doing one's best, implies that he was obligated to do.

N o w , if after all his profession, he cannot bear any opposition to his opinion, if he cannot so much as give a patient hearing, much less examine and weigh the arguments on the other side, does he not plainly confess it is prejudice governs him? and it is not the evidence of truth, but some lazy anticipation, some beloved presumption, that he desires to rest undisturbed in. For, if w h a t he holds be, as he gives out, well fenced with evidence, and he sees it to be true, what need he fear to put it to the proof?

In N c a l W o o d , The Politics of Locke's Philosophy, there is a fine chapter (pp. 1 2 1 - 4 8 ) on the "Ideal ofBourgeois M a n " which is implicit in Locke's Essay. " T h e ideal, almost an archetype of bourgeois man and differing markedly from the traditional conception of the a r i s t o c r a t . . . A reconstruction of the i d e a l . . . yields a portrait of an individual w h o is commonsensical and pragmatic, a w a r e of his own fallibility, sociable and tolerant. A b o v e all, Locke's ideal man is an individualist. H e is a self-directed man w h o labors industriously in a persevering and sober manner, is invariably moderate and self-disciplined in the pursuit of happiness, is calculating and prudent in judgment. Locke was offering his bourgeois readers a model for emulation as well as a mirror of themselves" (p. 6 ) .

F o r we impose upon ourselves, which is the strongest imposition of all others; and we impose upon ourselves in that part which ought with the greatest care to be kept free from all imposition."

R e a s o n , he says, consists in nothing but the perception of the connexion there is between the ideas, in each step of the deduction, whereby the mind comes to see, either the certain agreement or disagreement of any two ideas, as in demonstration, in which it arrives at knowledge, or their probable connexion, on which it gives or withholds its assent, as in opinion . . . F o r as R e a s o n perceives the necessary, and indubitable connexion of all the ideas or proofs one to another, in each step of any demonstration that produces knowledge: so it likewise perceives the probable connexion of all the ideas or proofs one to another, in every step of a discourse, to which it will think assent due. This is the lowest degree of that, which can be truly called reason. ( i v , x v i i , 2 ) 74

A y c r s remarks, in the light of passages such as this, that "it is worth noting t h a t . . . it is the connection between subject and predicate which we are said to perceive, not (as a n y modern notion of 'perceiving probabilities' would surely presume) the connection between a hypothesis and the evidence for it" (Locke.: Volume I: Epistemology, pp. 1 0 5 - 6 ) . T h e point, is of course, correct; but it's a point that pertains to Locke's view in general of our knowledge of arguments. In explicating Locke, I have been speaking, and shall continue to speak, of "perceiving" the relation of a conclusion to premises and of a proposition to evidence; Locke thought that the proper analysis of that was in terms of "perceiving" the relation between a subject-idea and a predicate-idea by w a y of "perceiving" relationships among intermediate ideas.

W h a t I have presented in the text above is part of Locke's official definition of "Reason" in the Essay. However, just before saying that Reason "consists in nothing but the perception...," Locke said that Reason "contains" two "other intellectual faculties, viz., sagacity and illation" (inference). Obviously there is confusion here; but it is purely verbal, and relatively harmless. I shall follow what appears to me to be Locke's dominant practice, of taking Reason to be a faculty of "perception." Essentially the same explanation which I quote in the text above is offered in Locke's early Essays on the Law of Nature (p. 1 2 5 ) , and is repeated in his Second Letter to Stillingfleet thus: "the agreement or disagreement of two ideas . . . perceived by the intervention o f a third, which I, and as I guess other people, call reasoning, or knowing by reason" (Works 1 1 1 , 2 3 2 ) . In another passage from the same letter, however, he speaks of all cases of "perception," whether immediate or non-immediate, as the result of the exercise of Reason: "the perception of the agreement or disagreement of ideas, is either by an immediate comparison of two ideas, as in self-evident propositions; which w a y of knowledge of truth, is the w a y of reason; or by the intervention of intermediate ideas, i.e. by the deduction of'one thing from another, which is also the w a y of reason" (in, p. 3 5 3 ) . In a passage from his First Letter to Stillingfleet, Locke includes yet more capacities under what he calls Reason, namely, the capacity to form general, relative, and complex ideas out of simple ones: "mere ideas are the objects of the understanding, and reason is one of the faculties of the understanding employed about them; and . . . the understanding, or reason, whichever your lordship pleases to call it, makes or forms, out of the simple ones that come in by sensation and

A n d therefore 1 never denied that reason was employed about our particular simple ideas, to make out of them ideas general, relative, and complex; nor about all our ideas, whether simple or complex, positive or relative, general or particular: it being the proper business of reason, in the search after truth and knowledge, to find out the relations between all these sorts of ideas, in the perception whereof knowledge and certainly of truth consists" (m, 7 0 — 1 ) . Lastly, in a passage from the Second Letter, Locke says that though in the Essay he treated Reason "no otherwise than as a faculty," yet "reason" m a y also be used "as standing for true and clear principles, and also as standing for clear and fair deductions from those principles" (m, 4 2 4 ) .

Cf. 'third Letter for 'toleration; Works vftiT- " T h a t which hath evidence enough to make one man certain, has not enough to make another so much as guess it to be true; though he has spared no endeavour or application in examining it." Though the theme of the infallibility of Reason plays an exceedingly dominant role in Schouls' book on Locke, Reasoned Freedom, Schouls, oddly, never considers what the infallibility of Reason consists in, other than to suggest, in one passage, that it consists in the infallible ability to pick out episodes of Reason "perceiving" something. If we take it to consist in this, then, as I shall argue, Locke does not hold that Reason is infallible.

T h o u g h the phrase is mine, Locke himself regularly uses the medical metaphor ofdisease. He speaks of "the variety of distempers in men's minds" (Conduct, §38; Works 1 1 , 3 8 4 ) ; and he says that there are perhaps as many "weaknesses and defects in the understanding, either from the natural temper of the mind, or ill habits taken up . . . as there are diseases of the body, each whereof clogs and disables the understanding to some degree, and therefore deserves to be looked after and cured" (Conduct, § 3 8 ; Works 11, 3 4 9 ) . A s one would expect, he also regularly speaks,as in that last passage, of "cures" and "remedies" (e.g., Conduct, § 4 1 ; Worksn, 3 8 8 - 9 ) .

O n inculcated principles, see also Essay i , i i i , 2 2 - 7 . By no means, however, does Locke think that even careful examination will always result in getting things right. " T h e tempers of men's minds; the principles settled there by time and education, beyond the power of the man himself to alter them; the different capacities of men's understandings, and the strange ideas they are often filled with; arc so various and uncertain, that it is impossible to find that evidence . . . which one can confidently say will be sufficient for all men" (Third Letter for Toleration; Works \,2<jj). Furthermore, " W h o is there almost that has not prejudices, that he does not know to be so . . . ? It is not everyone knows, or can bring himself to DesCartes's w a y of doubting, and strip his thoughts of all opinions, till he brings them to self-evident principles, and then upon them builds all his future tenets" (ibid., 2 9 7 - 8 ) .

A somewhat similar point played a very large role in Descartes's thought, as all of Locke's readers, then and now, would recognize. Descartes's precise point, as I shall argue, is that praejudicia inhibit a person's ability to distinguish between propositions of which he or she is certain and propositions of which he or she is not certain.

A similar point was m a d e by Locke already in n,ix,8 and to, where he observed that the object judgments we are habitually disposed to make, upon having certain sensory input, alter our perceptions. " W e are farther to consider concerning perception, that the ideas we receive by sensation, are often in grown people altered by the j u d g m e n t , without our taking notice of it."

H e r e is p a r t o f L o c k e ' s s t a t e m e n t o f his t h i r d s o u r c e o f " w r o n g measures of probability": Probabilities, which cross men's appetites, and prevailing passions, run the same fate. L e t never so much probability hang on one side of a covetous man's reasoning, and money on the other; and it is easy to foresee which will outweigh. E a r t h l y minds, like mud walls, resist the strongest batteries: and though, perhaps, sometimes the force of a clear argument m a y make some impression, yet they nevertheless stand firm, keep out the enemy truth, that would captivate, or disturb them. Tell a man, passionately in love, that he is jilted; bring a score of witnesses of the falsehood of his mistress, 'tis ten to one but three kind words of hers, shall invalidate all their testimonies . . . W h a t suits our wishes is forwardly believed, is, I suppose, what every one hath more than once experimented [experienced]: and though men cannot always openly gainsay, or resist the force of manifest probabilities, that make against them; yet yield they not to the argument.

It is worth quoting Schouls' summary: " A person avoids being incorporated into the mechanism of nature through the complex act that includes suspension of natural desires, examination of these desires and their potential consequences, contemplation of true good, judgment of the suspended desires in terms of the good contemplated, and submission to the outcome of that j u d g m e n t " (p. 1 4 5 ) . This is Locke's own summary: "This at least I think evident, that we find in ourselves a power to begin or forbear, continue or end several actions of our minds . . . barely by a thought or preference of the mind ordering, or as it were commanding the doing or not doing such or such a particular action. This power which the mind has, thus to order the consideration of any idea, or the forbearing to consider it . . . in any particular instance is that which we call the will" (n,xxi,5).

But though we cannot hinder our knowledge, where the agreement is once perceived; nor our assent, where the probability manifestly appears upon due consideration of all the measures of it: Y e t we can hinder both knowledge and assent, by stopping our enquiry, and not employing our faculties in the search of any truth.

It appears to me that Leibniz, in the New Essays, was entirely in agreement with Locke on the power of the will with respect to belief. Beliefs, he says, "are inherently involuntary" (p. 5 2 0 ) ; "nevertheless we can bring it about indirectly that we believe what we want to believe" (P- 5 7 ) - H e then gives examples of the Lockian sort. Accordingly, "a man is not responsible for having this or that opinion at the present time, b u t . . . he is responsible for taking steps to have it or not have it later on. So that opinions are voluntary only in an indirect w a y " (p. 4 5 6 ) . 1

O n the distinction between internalist and externalist criteria for the presence of doxastic merits, see W m . Alston, "Internalism and Kxternalism in Epistemology," in Alston, Epistemic Justification: Essays in the Theory of Knowledge (Ithaca, Cornell University Press, 1 9 8 9 ) . Here is one exception, from his T h i r d Letter lor Toleration: "the equality that is here the question, depends not upon the truth of the opinion embraced; but on this, that the light and persuasion a man has at present, is the guide which he ought to follow, and which in his judgment of truth he cannot avoid to be governed b y " (Works v , 3 3 4 ) .

mindless haste. B u t suppose that as a matter of fact I a m mistaken in one or the other of these beliefs. L o c k e thinks, implausibly so it seems to me, that a proposition will never phenomenologically a p p e a r to h a v e a certain probability on certain propositions w h e n it does not. But w e h a v e seen that L o c k e nonetheless admits the possibility of error at all three of these points. W h a t now ought I to do? W h a t a m I epistemically culpable for not doing? Suppose, in the first place, that I a m mistaken about the c h a r a c t e r of the evidence. Locke's answer is apparently that I ought to continue collecting evidence until it is in fact satisfactory; I a m doxastically culpable unless I do this. Suppose, alternatively, that I a m right about the c h a r a c t e r of the evidence but w r o n g about the probability. Locke's answer is that I ought to proportion m y level of confidence in the proposition to w h a t is in fact its probability on the evidence; if I do not do that, I a m doxastically guilty, doxastically culpable, a doxastic w r o n g d o e r . B u t surely both answers are mistaken. F o r suppose that I e m b r a c e d Locke's criterion. T h e n I would, a c c o r d i n g to the criterion, be doxastically guilty if I did not do w h a t I did not on careful reflection believe that I should do. A n d if I applied the criterion in a c c o r d a n c e with m y beliefs, I would be doxastically guilty for doing w h a t on careful reflection I believed that I should do. T h a t is one a p p r o a c h to the situation: from the side of where m y guilt would lie. B u t w e can also a p p r o a c h it from the side of guidance. I f I offer you a suggestion as to the best procedure for achieving a certain goal, if you accept it as such, and if the procedure comes in stages, then in trying to implement later stages you h a v e to g o by your beliefs as to the results of trying to implement earlier stages. W h a t else could you go b y ? S o whether w e a p p r o a c h a proposed rule for the determination of one's doxastic responsibilities from the side of responsibilities, or from the side of g u i d a n c e , w e get the same result: In one's attempt to follow later stages of the rule, one has to go by w h a t one believes to be the result of h a v i n g attempted to follow earlier stages. O n e can attach conditions to these beliefs - for example, that the beliefs be formed reflectively. B u t still, one must go b y w h a t one believes. 9 S

A final question. In formulating Locke's principle of proportionality, I have said nothing about believing the proposition in question on the basis of the evidence - or more broadly, about basing one's level of confidence on the evidence. I have not done so because Locke (with rare exceptions) does not do so. But is this another deficiency in his principle, as it stands? W h a t if 1 follow all the principles but then believe the proposition in question not on the evidence but on untested sayso? W o u l d that count as doing my best?

O n e last question calls out for reflection: D o w e in fact h a v e the v o l u n t a r y control over belief and levels of confidence w h i c h Locke's principles presuppose? N o doubt w e can b y acts of will implement the first two principles of evidence and appraisal. O r rather, a n y doubts on this score will arise not from doubts as to whether w e h a v e it in our p o w e r to decide to collect evidence and to decide to determine its evidential force but from doubts as to the clarity of the notions of satisfactory evidence and conditional
probability. It is when
we
arrive at the principle of proportionality that doubts arise. Is it in our p o w e r to do w h a t the principle of proportionality presupposes that w e are able to do? W h a t does the principle actually presuppose? T o answer this question it will be useful to h a v e a t a x o n o m y distinguishing different types of control by the will of belief. In his article " T h e Deontological Conception of Epistemic J u s t i f i c a t i o n , "
96
W i l l i a m P. Alston constructs
exactly such a taxonomy. I propose b o r r o w i n g it. In constructing his t a x o n o m y , Alston explicitly considers not just belief but the three propositional attitudes of believing, rejecting, and withholding; in this respect his discussion, unlike most recent discussions on belief and the will, proves directly relevant to Locke's claims. His t a x o n o m y fails us, though, in not at all considering the relation of the will to levels of confidence. O n e preliminary matter must be considered before we look at Alston's distinctions and arguments. In the course of his discussion Alston announces and argues for a certain principle as follows: one has control over a given type of state only if one also has control over some field of incompatible alternatives. T o have control over believing that p is to have control over whether one believes that p or not, that is, over whether one believes that p or engenders instead some incompatible alternative. T h e power to choose A at will is the power to determine at will whether it shall be A or (some form of) not-A . . . If the sphere of my effective voluntary control does not extend both to A and to not-A, then it attaches to neither. I f I don't have the power to choose between A and not-A, then we
9 6
It m a y have been Locke's view that as a matter of psychological fact this could not be; if one follows the principles, then one just will, as a matter of psychological fact, base one's level ofconftdence on the evidence. But even if he did not hold this, it's not clear that Locke need have added this additional stipulation. F o r if in fact one's belief is in accord with the principle of proportionality, then w h a t difference does it make, for Locke's purposes, on what basis one holds the proposition in question? In Epistemic Justification: Essays in the Theory of Knowledge (Ithaca, Cornell University Press, - 8 9 ) , PP-i 1 5 - 5 2 . IO

are without sufficient reason to say that I did A at will, rather than just doing A , accompanied by a volition. 97
I
find
Alston's
formulations
here a m b i g u o u s as between
two
different principles: ( 1 ) T o be able to choose A at will, I must be able to choose A at will and be able to choose n o t - A at will. (2) T o be able to choose A at will, I must be able to choose at will whether A or n o t - A . T h e difference between these two principles is relevant to interpreting L o c k e , since, when it comes to belief, L o c k e a p p a r e n t l y held that, in some cases, w e h a v e the p o w e r specified in the latter but not that specified in the former. L o c k e apparently held that one is frequently able to choose at will to withhold believing P, thus able to choose at will whether one will believe P or not believe P; but one is (almost) never able to believe propositions at will, thus (almost) never able to choose at will to believe P and choose at will to withhold belief from P. T h o u g h some of Alston's formulations seem to me more apt as expressions of principle ( 1 ) and some more apt as expressions of principle ( 2 ) , the reason he offers for the principle would seem to justify only the weaker principle ( 2 ) , which L o c k e m a y h a v e assumed, and not the stronger principle ( 1 ) , which he clearly denies. Alston distinguishes
three modes of voluntary control: direct
control, long-range control, and indirect influence.
In turn, he
distinguishes two kinds of direct control: basic and non-basic. A n agent has direct control over some act or state when "the agent is able to carry out the intention 'right a w a y , ' in one uninterrupted intentional act, without h a v i n g to return to the attempt a n u m b e r of times after h a v i n g been occupied with other m a t t e r s . "
98
Agents have
basic (direct) control over some act or state if their doing it does not require their doing it by w a y of doing something else voluntarily; intentionally raising one's a r m and turning one's thought to the prospects of one's favorite soccer team, are examples. B y contrast, agents h a v e non-basic
(direct) control over some act or state if they
are able to do it only b y doing something else voluntarily. T u r n i n g on a light would be an example. W e h u m a n beings are able to do this only by flipping or turning or pressing a switch, or something of that sort. Alston argues that believing, rejecting, and withholding are rarely Ibid.,

if ever within the direct control of h u m a n agents - either within their basic direct control or within their non-basic direct control. H e notes that his " a r g u m e n t for this, if it can be called that, simply consists in asking you to consider whether you have a n y such p o w e r s . "
99
A s for
himself, he finds that he does not; and he very m u c h doubts that other people are different from him in this regard. F o r e x a m p l e , asks Alston, do I h a v e effective, direct, basic or non-basic "voluntary control over whether I do or do not believe that the tree has leaves on it when I see a tree with leaves on it just before me in b r o a d d a y l i g h t with m y eyes w o r k i n g p e r f e c t l y ? "
100
His answer is that "it is perfectly
clear that in this situation I h a v e no p o w e r at all to refrain from that belief." In other situations, one would not h a v e it in one's p o w e r to come to believe. But suppose that I h a v e a motive of a roughly L o c k i a n sort. S u p p o s e that I am firmly persuaded that if I a m not entitled to believe some proposition, I ought to give up believing it - then and there; and that I believe, in addition, that I am not entitled to this belief. C o u l d I then give it up? M i g h t it be that the reason w e cannot retract assent from an immediate perceptual belief in the sort of case Alston envisages is that w e lack an a d e q u a t e motive? Alston does
not
consider this possibility. It seems clear to me, however, that even if I had this persuasion and this belief, I would not be able to withhold belief from the proposition in question in the situation envisaged. A n d so, correspondingly, for cases of coming to believe. W e must not d r a w the conclusion that everyone in the sort of situation envisaged will ineluclably
believe that there is a leafy tree
before him or her. If for some reason one believes falsely that one is looking at a painting of a tree rather than at a tree, then, though one is in fact seeing a leafy tree, one will not believe that the tree before one has leaves on it. W h e t h e r or not the perceptual experience of seeing a tree produces in one the belief that there is a tree before one depends, a m o n g other things, on the beliefs one brings to the situation. B u t in the case envisaged, w h a t one comes to believe depends on one's sensory experience plus one's other beliefs; it does not depend on whether one decides to believe, or on whether one decides or does not decide to withhold belief. W h e n I see a tree while believing that I a m looking at a painting, I do not decide not to believe that I a m seeing a tree. T h e disposition to believe that there is a tree before me is simply not

activated. T h o u g h the requisite sensory experience is present, the belief that I a m looking at a painting functions to inhibit
the
activation of the disposition. L e t us take a m o m e n t to consider an e x a m p l e of the sort w h i c h occupied so m u c h of Locke's attention: Believing w h a t someone says on his or her sayso. S u p p o s e a m a n tells me that he has just seen a c a r accident on the corner a block a w a y .
U s u a l l y those w h o h a v e
discussed belief and the will would put the following question to this situation: Is it then in m y p o w e r to believe at will and also in m y p o w e r to not believe at will? B u t w e must divide the question. F o r w e h a v e seen that someone might hold that it is not in our p o w e r to believe at will, though it is in our p o w e r to refrain from believing. L e t it be noticed that w e do sometimes say, " I decided not to believe h i m . " ( T h o u g h w e also say, " I decided to believe him.") It seems to me clear that if I do believe him, that will never be because I decided to do so; and if I don't, that will never be because I decided not to. It is true that a good deal of deciding typically goes into such a situation; and perhaps it is this w h i c h leads us in ordinary speech to speak of deciding not to believe someone. I can decide to attend closely to the facial expressions of the reporter, to his agitation or lack thereof, to the fact that I heard nothing though I w a s outdoors a block a w a y , to the fact that e v e r y b o d y in view seems to be going about their ordinary business in their o r d i n a r y w a y , and so on. A l l this and more I c a n , by act of will, take note of. It m a y be that after initially believing the person and then doing such things I no longer believe him. But then \ find myself not believing him. I don't decide not to believe him. A n d now in general: I think it is as decisively clear as a n y t h i n g ever is in philosophy that when w e find ourselves believing something, w e cannot by act of will give up that belief; nor, when w e find ourselves not believing something, can w e b y act of will begin believing. S u c h actions are simply not within our p o w e r . Perhaps it will help to take note of two sorts of mental acts w h i c h are (in good measure) under the direct control of the will and w h i c h are so closely related to believing as to be easily confused with it. T h e r e is, for one thing, the phenomenon of admitting or not admitting that one believes or does not believe -
admitting to others, but
perhaps more importantly, to oneself. Often w e h u m a n beings find the phenomenon
of believing such-and-such, or of not believing
such-and-such, painful. S o w e determine not to a c k n o w l e d g e our situation -- not to a d m i t that w e do believe or not a d m i t that w e do not

believe. W h e n someone else assumes that w e believe, w e passionately repudiate the assumption. W e go out of our w a y to avoid acting and speaking as believers w o u l d normally act and speak. W h e n the belief comes to mind, w e immediately think of something else. A n d so forth. T h e w a y s of the heart are devious. V e r y m u c h - though perhaps not all - of w h a t goes into not admitting one's belief or disbelief is under the direct control of the will. Believing must also be distinguished from w h a t one might call accepting. P a r a d i g m a t i c examples of w h a t I h a v e in mind by accepting , o c c u r in religious revival meetings. T h e evangelist urges those in the audience w h o h a v e not "accepted J e s u s " to come forward and make their decision. S o m e do come forward; they speak of h a v i n g decided to accept J e s u s . A striking feature of conversion literature is that though the l a n g u a g e is sometimes that of being o v e r w h e l m e d , of resisting but then no longer being able to resist, at other times it is that of deciding. I suggest that these two w a y s of speaking fit two closely related, yet distinct phenomena: believing versus accepting. O n e finds oneself believing; one decides to accept. Deciding to accept some proposition consists, roughly, of deciding to say " Y e s " to that proposition and then as m u c h as possible letting that Y e s - s a y i n g play the role in one's emotional, motivational, and intellectual life that believing it w o u l d play. D e c i d i n g to accept is, if you will, deciding to e n g a g e in, and to let oneself be engaged in, a certain role - the role of believer. T h e r e need be nothing insincere or deceptive in such role-playing; a n y such connotation
w h i c h the
phrase "role-playing" carries must be discarded. M y o w n experience is that often it is difficult, and sometimes impossible, for me to determine whether m y stance t o w a r d a certain proposition is that of accepting or that of believing. T h e phenomenon I h a v e been calling accepting is different from that to w h i c h some philosophers h a v e called attention as important in science, and w h i c h is best called accepting-as.
A scientist might accept a
certain theory as a w o r k i n g hypothesis. Similarly, a general might accept the guess of one of his lieutenants concerning the enemy's d e p l o y m e n t offerees as h a v i n g the least calamitous consequences if it proves mistaken. In cases of accepting-as,
the phenomenon of p l a y i n g
the role of believer, w h i c h I h a v e identified with accepting, m a y be missing. T h e researcher might believe that the hypothesis is false and yet accept it as a w o r k i n g hypothesis - to see w h e r e it goes. Believing versus admitting one's belief. Believing versus accepting.

A c c e p t i n g versus accepting-as. T h e s e are subtle distinctions within a fascinating terrain. A whole field for investigation opens u p before us. But this is not the occasion to step into it. M y aim is not to explore the p h e n o m e n a but only to make the necessary distinctions. S o m e of w h a t goes into not admitting that one believes such-and-such is within one's direct v o l u n t a r y control. S o too accepting is within one's direct voluntary control, as is accepting-as. B u t believing
and
withholding are not. A n y rule or principle or method which presupposes that they are must be rejected as presupposing something false. But
w h a t about
Alston's category of long-range
control
over
propositional attitudes? Surely w e c a n often take steps designed to bring it about that w e shall wind up with some propositional attitude toward some proposition. T h a t is to say, some specific propositional attitude t o w a r d some specific proposition. I can read the encyclopedia with
the
aim of coming
to believe
some
proposition
or other
concerning the land area of Pakistan. O r , if I already h a v e a particular proposition
on
the matter in mind,
I can read
the
encyclopedia with the aim of taking up some propositional attitude or other toward that proposition — belief, disbelief, withholding. B u t given a specific proposition and a specific attitude, I c a n sometimes also take steps to bring it about that I h a v e that attitude toward that proposition. S o m e t h i n g said by Pascal is frequently cited in the literature as an example: If one wants to believe C a t h o l i c d o g m a but finds oneself not doing so, one thing which has a c h a n c e of securing one's desire is attendance at C a t h o l i c mass. O t h e r strategies might work as well -
for e x a m p l e , reading C a t h o l i c polemics against
O r t h o d o x y , Protestantism, other religions, and atheism, while not reading w h a t the other side has to say in response. But I agree with Alston's assessment of all this: T h e results are too unpredictable to g r o u n d obligations to believe, reject, and withhold. T h e reason one can h a v e an obligation to turn on the light, even though that is not within one's basic control, is that there is a stable and well-known causal connection between flipping the switch and the light going on. In this matter of taking steps to bring about a specific propositional attitude t o w a r d a specific proposition, there are rarely if ever such stable and wellknown causal connections.
In
Alston's words: It is very dubious that we have reliable long-range control over any of our beliefs, even in the most favorable cases, such as beliefs about religious and philosophical matters and about personal relationships. Sometimes people
The Vision:
Lei Reason be Tour Guide in Believing
115
succeed in getting themselves to believe (disbelieve) something. B u t I doubt that the success rate is substantial. T o my knowledge there are no statistics on this, but I would be very much surprised if attempts of this sort bore fruit in more than a very small proportion of the cases . . . T h u s a long-range control thesis does not provide much grounding for deontologism, even for the sorts of propositions people do sometimes try to get themselves to believe or disbelieve. M u c h less is there any such g r o u n d i n g for those propositions with respect to which people don't normally even try to manipulate their attitudes. 101
T h i s leaves us, lastly, with the c a t e g o r y of indirect v o l u n t a r y control over assent. U n d o u b t e d l y w e do often h a v e such control. T h o u g h I now h a v e no belief whatsoever as to the land area of Pakistan, it is within my p o w e r by act of will to do things w h i c h will result in m y h a v i n g a belief on the matter. A n d perhaps sometimes I ought to. T h u s an ethic of belief w h i c h assumes indirect v o l u n t a r y control over believing and withholding and nothing more will, so far forth, be acceptable; and only those ethics w h i c h assume such control and nothing more will be acceptable. W i t h this m a p in hand, let us consider whether w e h u m a n beings do in fact h a v e the powers of will necessary for a p p l y i n g Locke's principle of proportionality. Pretty clearly L o c k e ascribed to the will powers w h i c h , in the light of the foregoing, it does not have. His overall view seems to h a v e been that though deciding to believe is a rare event - in his first Letter Concerning
Toleration
he said that "to believe
this or that to be true does not depend upon our will" - nonetheless one can decide not to believe some proposition just so long as one does not j u d g e it to h a v e a rather high probability on w h a t one judges to be satisfactory evidence. T h a t view, in the light of the foregoing, is untenable. B u t our concern here is not to appraise the tenability of Locke's o w n expressed views as to the powers of the will, but rather, to appraise the tenability of his proposed doxastic practice in the light of the foregoing conclusions concerning h u m a n nature. A n d it is much less obvious that Locke's proposed practice presupposes powers of the will over belief w h i c h it does not h a v e than that he himself in the course of his discussion ascribed such powers to the will. Suppose that one has m a d e a suitably serious attempt to apply the principles of evidence and appraisal in a given case; and that the result is that one now believes that one has a satisfactory body of evidence concerning P, and that the probability of P on that evidence is high — say, -g. It w a s clearly Locke's view that one would then just ',;!••

find oneself believing P; no act of will is involved. I t w a s also his v i e w that if one doesn't believe the evidence is satisfactory, or if one doesn't believe that one has discerned the probability of the proposition on one's evidence, then one can resist w h a t e v e r inclinations one might h a v e to believe or disbelieve P. Perhaps now and then one can even, in such cases, decide to believe P. B u t these are cases in w h i c h one j u d g e s that one's attempt to a p p l y one of the earlier principles in
the
sequence of evidence, appraisal, and proportionality has not proved successful. A n d one is to m o v e on to a later principle only if one's serious attempt
to implement
the earlier principles has proved
successful, in one's j u d g m e n t . Incidentally, one point L o c k e leaves obscure is w h a t obligations w e have, if any, concerning belief for those cases of m a x i m a l concernment where we haven't yet, in our j u d g m e n t , successfully applied the first two principles. If it was his view that, in cases of m a x i m a l concernment, w e are to suspend
belief
until
such
time
as w e j u d g e
ourselves
successfully to h a v e applied the principles, then our discussion a b o v e leads us to d o u b t that this is possible. B u t his proposal does not require him to say this. B a c k , then, to our example: S u p p o s e one finds oneself believing P, in the situation described. W h a t , then, about the principle of propor tionality; how does it enter the picture? A p p a r e n t l y it was Locke's view that though belief is compelled in such a situation, some particular degree of firmness of belief is not compelled. F o r if that were also compelled, w e would need no third principle; everything that one could do would already h a v e been done b y a p p l y i n g the first two principles of evidence and appraisal. B u t this view is most implausible. T h e firmness with w h i c h w e believe things is no more under the direct control of the will than believing is. In particular: if, in the case described, I believe that Pis highly probable on satisfactory evidence, I shall also find myself believing P with considerable
firmness.
C o u l d L o c k e h a v e conceded this point and revised his proposal accordingly? Y e s , he could h a v e . T h e proposal w o u l d then be that in cases of m a x i m a l concernment w e are obligated to a p p l y the two principles of evidence and appraisal. Locke's proposal is not rendered incoherent b y removing from it the principle of proportionality. Y e t I j u d g e that L o c k e would be acutely u n h a p p y to remove it; in his various statements
of his
proposal
it is often
the
principle
of
proportionality w h i c h occupies the center of attention. O n e of his reasons for thinking the principle important w a s his conviction that

Let Reason be Tour Guide in Believing
117
social tranquility will be promoted if w e all follow the principle of proportionality; people will then no longer fight to the death for propositions whose probability is well short of m a x i m a l . S o far, then, w e h a v e found no decisive conflict between Locke's proposal, on
the one
hand, and the facts, on the other
hand,
concerning belief and the will. B u t now consider a case of the sort w h i c h fills the pages of H u m e and R e i d : a case of a belief being formed in one immediately and ineluctably in a situation in w h i c h evidence, of the sort L o c k e allows, for the truth of the proposition is weak. Suppose that in good daylight and with m y eyes working properly I see a leafy tree before me, and find myself believing immediately that there is a leafy tree before me. T h a t is to say, suppose that some process of belief-formation other than the process of believing on the basis of other beliefs produces this belief in me. S u p p o s e further that this case is, and
that
I j u d g e it to be,
a matter of m a x i m a l
concernment to me. A n d suppose lastly that on the evidence of the totality of facts which (on Locke's view) I directly "perceive" this proposition has low probability
and that I j u d g e it to h a v e low
probability. H u m e and R e i d relentlessly a r g u e that, as a matter of fact, the proposition that there is a leafy tree before me will h a v e very low probability on that evidence; I j u d g e them to be right about that. L o c k e tells us two things about this situation: that w e will, in such a case, just find ourselves disbelieving P; and that w e ought to disbelieve it with considerable
firmness.
B u t surely he is mistaken on
both
counts; H u m e and R e i d are right. O u r j u d g m e n t , that arguments from facts of direct awareness to the existence of external objects are weak arguments, has no effect whatsoever on the formation
of
immediate perceptual beliefs; such beliefs are formed in us ineluctably. A n d since w e cannot disbelieve them with a n y firmness whatsoever, it is not the case that w e ought to. But notice: W e h a v e still not turned u p a n y point at w h i c h Locke's proposal decisively conflicts with the facts concerning belief and the will.
It turns out that on this issue, L o c k e emerges triumphant
-
provided he surrenders the principle of proportionality! W h a t w e h a v e found instead is that L o c k e was mistaken in an assumption he m a d e about the dispositions
w h i c h form our beliefs. H e assumed that
one will ineluctably believe or disbelieve a proposition according as one judges it p r o b a b l e or i m p r o b a b l e on w h a t one j u d g e s to be satisfactory evidence consisting of facts of w h i c h one is directly a w a r e . It w a s the great merit of H u m e and R e i d , in the generation following
n8

L o c k e , to h a v e discerned that L o c k e was mistaken about this, to h a v e argued the point with power, and to h a v e pursued the implications of its acknowledgment. O u r perceptual beliefs, our inductive beliefs, our m e m o r y beliefs h a v e at best low probability on the facts of w h i c h w e are (on Locke's view) directly a w a r e . Discerning that serves neither to dislodge those beliefs from our mind nor to place us in a situation w h e r e w e can by direct act of will dislodge them. E v e n when w e h a v e the time, our nature often prevents us from doing that which L o c k e praises as doing our epistemic best.

I remarked at the beginning of my exposition that the genesis of the Essay
was a resolution L o c k e formed after perplexities arose in a
discussion a m o n g some friends and himself "about the principles of morality and revealed religion." H a v i n g described the doxastic practice he recommends, L o c k e did not neglect to go back and indicate how it applied in these two areas; it w a s these areas w h i c h L o c k e a l w a y s regarded as properly of the greatest "concernment''''
for
every h u m a n being. S o let us consider these two applications. A n d let us begin with Locke's discussion of revealed religion; w h a t he says about the application of the proposed practice to this is both the presupposition of, and more a m p l e than, w h a t he says about its application to morality influential.'

In the first edition of the Essay,
L o c k e devoted one rather long
chapter to the topic of faith and reason. H o w e v e r , so vexed w a s he by the enthusiasts - people claiming private revelations from G o d without (to his mind) h a v i n g a n y good evidence thereof - that in the fourth edition he inserted an entire chapter devoted to these people w h o "flattered themselves with a persuasion of an immediate intercourse with the Deity, and frequent communications from the Divine Spirit" ( i v , x i x , 5 ) . T o the beliefs of these people, that they had received private revelations from G o d , L o c k e issued w h a t might be called the evidenlialist
challenge.

obligated to try our best to get in touch with reality on these matters. A c c o r d i n g l y , unless these people proportion the firmness of their belief
to

satisfactory evidence,
they
are
acting
irresponsibly. Since L o c k e w a s convinced that the enthusiasts were not doing this, his evidentialist challenge became an objection.
H e had written his Letter Concerning
Toleration;
evidentialist though he
viewed enthusiasm as a social d a n g e r , he would not r e c o m m e n d the forcible suppression of such people. Instead he preached that they were violating their doxastic obligations.
Sometimes, of course,
inducing guilt feelings in people, or social disapproval in their neighbors, is as effective in suppressing their behavior as d r a g g i n g them before the law. T h e doxastic practice L o c k e w a s proposing could serve as effectively as an instrument of social p o w e r as those practices he w a s opposing! Locke's attack on the enthusiasts provides a good entrance into his reflections on faith and reason. H e did not d e n y - indeed he affirmed that G o d can and sometimes still does "enlighten men's minds in the apprehending of certain truths, or excite them to good actions by the immediate influence and assistance of the H o l y Spirit" ( i v , x i x , i 6 ) . ; " G o d . . . cannot be denied to be able to enlighten the understanding by a ray darted into the mind immediately from the fountain of lights" ( i v , x i x , 5 ) . B u t L o c k e w a s confident that in the case of the enthusiasts it w a s not G o d ' s enlightenment that accounted for their convictions but a disordered psyche, a " w a r m e d or overweening b r a i n " ( i v , x i x , 7 ) . T h e people susceptible to enthusiasm are those "in w h o m melancholy has mixed with devotion," along with
those
"whose conceit of themselves has raised them into an opinion of a greater familiarity with G o d , and a nearer admittance to his favor, than is afforded to others" ( i v , x i x , 5 ) . " T h e i r minds being
thus
prepared, w h a t e v e r groundless opinion comes to settle itself strongly upon their fancies, is an illumination from the Spirit of G o d , and presently of divine authority: and whatsoever odd action they find in themselves a strong inclination to do, that impulse is concluded to be a call or direction from heaven, and must be o b e y e d " ( i v , x i x , 6 ) . S o L o c k e charged the enthusiasts with irresponsibility. I f o n e is to believe responsibly that G o d revealed so-and-so on such-and-such an occasion, one's believing must be in accord with the "dictates of R e a s o n . " But is it clear that the enthusiasts w e r e violating Locke's principles? D i d not their religious experience supply them with the evidence required? L o c k e thought not. F o r when w e interpret their metaphors, w e see that to the question w h y they believe that G o d has spoken to

life
them, their answer is just that they believe it strongly. " I f they say they k n o w it to be true, because it is a revelation from G o d , the reason is good: but then it will be d e m a n d e d , how they know it to be a revelation from G o d . I f they say b y the light it brings with it, which shines bright in their minds, and they cannot resist; I beseech them to consider, whether this be a n y more than w h a t w e h a v e taken notice of already, viz., that it is a revelation because they strongly believe it to be true. F o r all the light they speak of is but a strong,
though
ungrounded persuasion of their minds that it is a truth" (iv,xix, 1 1 ) . In short, "their confidence is mere presumption: and this light, they are so dazzled with, is nothing, but an ignis fatuus
that leads them
continually round in this circle. It is a revelation, because they firmly believe it, and they believe it, because it is a revelation" ( i v , x i x , t o ) . Locke's analysis will leave even those believers sympathetic to his a p p r o a c h uneasy at a certain point. Is not G o d ' s p o w e r and freedom such that G o d might well reveal something to some person without providing to that person satisfactory evidence on w h i c h it is probable that G o d has revealed that? M i g h t G o d not simply effect in a person the firm conviction that G o d has revealed such-and-such to the person? But if w e agree that G o d could and might do this, and also agree with L o c k e that his proposed practice ought to be applied to all such cases, w e are then in the curious position of admitting that G o d m a y reveal something in the absence of a certain kind of evidence that G o d has done so, while yet resolving never in the absence of such evidence to believe that G o d has done so. Docs not following Locke's practice put us in risk of sometimes not believing w h a t G o d has revealed? T r u e , there is, in general, nothing paradoxical about a thesis w h i c h implies that there are states of affairs of a sort such that it is both causally possible that they occur and not causally possible that one be in a situation where one is permitted to believe that they occur. But
the case before
us seems special: W h y would
G o d reveal
something to us if G o d did not w a n t us to believe that G o d revealed it? A n d if G o d wants us to believe, are w e not at least permitted to believe? L o c k e never explicitly considers the matter. H e just
assumes
without a r g u m e n t that G o d would not reveal in an evidential void. " G o d , when he makes the prophet, does not u n m a k e the m a n , " says Locke:
He leaves all his faculties in their natural state, to enable him to j u d g e of his inspirations, whether they be of divine original or no. W h e n he illuminates

the mind with supernatural light, he does not extinguish that which is natural. If he would have us assent to the truth of any proposition, he either evidences that truth by the usual methods of natural reason, or else makes it known to be a truth, which he would have us assent to, by his authority, and convinces us that it is from him, by some marks which reason cannot be mistaken in. Reason must be our last judge and guide in everything. I do not mean, that we must consult reason, and examine whether a proposition revealed from God can be made out by natural principles, and if it cannot, that then we may reject it: but consult it we must, and by it examine, whether it be a revelation from God or not. ( i v , x i x , i 4 ) 103
L o c k e is confident that G o d will p l a y by the rules of evidence. T h e creating G r o u n d of our existence m a y indeed break through the crust of that existence to reveal things to us. B u t w e must insist that if It w a n t s us to believe that It has done so, It provide us with satisfactory evidence. L o c k e adds that our d e m a n d i n g of G o d that G o d authenticate God's revelation is something that G o d demands of us. L o c k e regards it as God's
will
that w e govern our assent
by the principle
of
proportionality in accord with the verdicts of R e a s o n . P r e s u m a b l y , then, G o d will oblige us, by offering us evidence that G o d has revealed so-and-so when G o d has. A n y revelation of G o d u n a c c o m panied by evidence would be idle chatter on G o d ' s part, to w h i c h G o d does not require us to p a y attention. But w h y does L o c k e think a n y t h i n g at all has to be done about the enthusiasts? W h y not leave them alone, on the ground that religion is a matter of individual taste? Because the enthusiasts weren't leaving others alone. Civil w a r had been r a g i n g in E n g l a n d . E n g l a n d had been torn apart by religious strife; and in this strife, the enthusiasts 1 0 3
Leibniz was both more subtle and more traditional in his understanding of the relation between faith and Reason. Commenting on Locke's view, he says that " I f you take faith to be only what rests on rational grounds for belie), and separate it from the inward grace which immediately endows the mind with faith, everything you say, sir, is beyond dispute. F o r it must be acknowledged that many judgments are more evident than the ones which depend on these rational grounds. Some people have advanced further towards the latter than others have; and indeed plenty of people, far from having weighed up such reasons, have never known them and consequently do not even have what could count as grounds for probability. But the inward grace of the Holy Spirit makes up for this immediately and supernaturally, and it is this that creates what theologians strictly call 'divine faith.' G o d , it is true, never bestows this faith unless what he is making one believe is grounded in reason otherwise he would subvert our capacity to recognize truth, and open the door to enthusiasm - but it is not necessary that all w h o possess this divine faith should know those reasons, and still less that they should have them perpetually before their eyes. Otherwise none of the unsophisticated or of the feeble-minded - now at least - would have the true faith, and the most enlightened people might not have it when they most needed it, since no one can always remember his reasons for believing" (New Essays, p. 4 9 7 ) .

were participants. Enthusiasm is socially pernicious; that's w h y something has to be done about it. Convictions such as those the enthusiasts display have as their "constant concomitant" the arbitrary exercise of "an authority of dictating to others, and a forwardness to prescribe to their opinion." Dogmatism in religion has authoritarianism in society as its c o m p a n i o n . " H o w almost can it be otherwise," says L o c k e , "but that he should be r e a d y to impose on others' belief w h o has already imposed
on his o w n ? W h o c a n reasonably expect
arguments and conviction from him in dealing with others whose understanding is not accustomed to them in his dealing with himself" ( i v , x i x , 2 ) ? W e h a v e already c o m e across Locke's claim that failing to apply the Lockian practice, when one ought to, amounts to "imposing" on oneself; his claim now is that the person w h o imposes on himself is likely to impose on others as well. T o this it m a y be added that to act as the enthusiasts act is to violate one's dignity as a h u m a n being, and to do so in that very domain of life which ought especially to manifest our dignity - namely, in religion. " T o this c r y i n g up of faith in opposition to reason, w e m a y , I think, in good measure, ascribe those absurdities that fill almost all the religions w h i c h possess and divide mankind . . . religion, which should most distinguish us from beasts, and ought most peculiarly to elevate us as rational creatures a b o v e brutes, is that where in men often appear most irrational, and more senseless than beasts themselves" (iv,xviii, i t ) . And
the enthusiasts arc failing in their duty. F a i t h , says L o c k e , "is
nothing but a firm assent of the mind: which if it be regulated, as is our duty, cannot
be afforded
to a n y t h i n g but upon
good
reason"
( i v , x v i i , 2 4 ) . A n d to the objection that no one c a n follow the L o c k i a n practice for all of his beliefs, L o c k e replies, as w e h a v e seen, that everyone can and ought to do so for religious belief: "everyone has a concern in a future life, which he is bound to look after. T h i s engages his thoughts in religion; and here it mightily lies upon him
to
understand and reason right" (Conduct, §8; Works 1 1 , 3 4 2 ) . E v e r y b o d y in E n g l a n d has the time it takes on S u n d a y s and holidays
(Conduct,§8;
Works 1 1 , 3 4 2 ) ! For
L o c k e , the decisive consideration establishing that faith is
belief (opinion) rather than knowledge is that faith lacks the kind or g r o u n d of certitude requisite for knowledge. In his S e c o n d Letter to E d w a r d Stillingfleet, Bishop of Worcester, L o c k e says that
"the
certainty of faith, if y o u r lordship thinks fit to call it so, has nothing to

do with the certainty of knowledge. A n d to talk of the certainty of faith, seems all one to m e as to talk of the knowledge of believing - a w a y of speaking not easy to me to understand . . . F a i t h stands by itself, and upon grounds of its own; nor c a n be removed from them, and placed on those of knowledge. T h e i r grounds are so fa.£ from being the same, or h a v i n g a n y t h i n g c o m m o n , that w h e n it is brought to certainty, faith is destroyed; it is knowledge then, and faith no longer" (Works
111,146).
L o c k e is willing to speak of the "assurance of faith"; he regards the N e w T e s t a m e n t as calling for that (in, 2 7 4 - 5 ) . B u t the assurance of faith, he insists, is to be distinguished from knowledge: " W i t h w h a t assurance soever of believing, I assent to a n y article of faith, so that I steadfastly venture m y all upon it, it is still but believing. B r i n g it to certainty, and it ceases to be faith" (in, 1 4 6 - 7 ) . M o r e specifically, the "assurance" of faith, as L o c k e understands it, is the steadiness of faith; an assured faith m a y be as steady and u n w a v e r i n g as knowledge: "the full assurance of their faith as steadily determines their assent to the e m b r a c i n g of that truth, as if they actually knew it" (m, 2 8 1 ) . " | T ] h i s assurance of faith m a y a p p r o a c h v e r y near to certainty, and not come short ofit in a sure and steady influence on the m i n d " (in, 2 7 6 ) . W h a t L o c k e denies, however, is that faith either can or should be held with the firmness which characterizes or accompanies k n o w l e d g e .

In his Fourth Letter for Toleration, Locke finds felicitious phrases for the two aspects of faith that he is distinguishing, namely "firm persuasion" and "full assurance." He furthermore suggests that the firmness of a person's belief will have behavioral manifestations: " M e n act by the strength of their persuasion, though they do not always place their persuasion and assent on that side on which, in reality, the strength of truth lies" (Works v , 5 6 4 ) . All of this raises an interesting question when combined with w h a t he says about martyrdom: " N o r is

T h e assumption underlying these points is that faith, in its very nature, is something different from knowledge. T h o u g h its assurance c a n and ought to be as high as that of (the beliefs which a c c o m p a n y or constitute) knowledge, and though its firmness m a y a p p r o a c h that of (those beliefs w h i c h a c c o m p a n y or constitute) knowledge, yet faith is not knowledge. L o c k e stands in that long line of Christian reflection w h i c h regards faith as a species of believing
on the basis of
revelation.
Specifically, faith is believing something on ( w h a t one takes to be) God's
revelation
of it.
And
this
is

different
from
the"perception" w h i c h L o c k e (officially) identifies with knowledge; "a definition of knowledge, w h i c h [is] one act of the mind, [does] not at all concern faith, w h i c h [is] another act of the mind quite distinct from it" (Second Letter to Stillingfleet; Works 1 1 1 , 2 8 2 ) .

did not regard the holding of theistic beliefs in
general as a matter of faith. A three-fold distinction must be m a d e in h o w h u m a n beings hold beliefs about G o d . Sometimes they hold them as mere matters of opinion, on the basis of tradition or whatever. Sometimes they hold them as that special form of opinion w h i c h is faith.
A n d sometimes they know them - demonstratively, however, not
intuitively ( i v , i i i , 2 i ; i v , x ) .

T o establish and implement this last
there among the many absurd religions of the world, almost any one that does not lind votaries to lay down their lives for it: and if that be not firm persuasion and full assurance that is stronger than the love of life, and has force enough to make a man throw himself into the arms of death, it is hard to know what is firm persuasion and full assurance . . . The persuasion they have of the truth of their own religion, is visibly strong enough to make them venture themselves" (ibid., 5 6 3 - 4 ) . W a s it Locke's view that it is inappropriate to hold one's faith with so much firmness (confidence) thai one is willing to give one's life for it? Consider this passage: " I know not what greater pledge a man can give of a full persuasion of the truth of anything, than his venturing his soul upon it, as he does, who sincerely embraces any religion and receives it for true. But to what degree soever of assurance his faith may rise, it [faith?] still comes short of knowledge" (Third Letter for Toleration; Works v, 1 4 5 ) . In his own w a y , then, Locke follows the practice developing in his time of distinguishing between natural religion and revealed religion. W e must not suppose, however, that on his view, one must first come to a natural knowledge of G o d and then come to faith. In his Second Letter to Stillingfleet he says, for example: " I f your lordship means, that to suppose a divine revelation, it is necessary to know, that there is simply an intelligent being; this also I deny. For to suppose a divine revelation, it is not necessary that a man should know that there is such an intelligent being in the world: I say, know, i.e. from things that he does know, demonstratively deduce the proof of such a being: it is enough for the receiving divine revelation, to believe, that there is such a being, without having by demonstration attained to the knowledge that there is a G o d . . . if nobody can believe the Bible to be of divine

• conviction, L o c k e offers a version of the cosmological a r g u m e n t , concluding thus: "from the consideration of ourselves, and w h a t w e infallibly find in our o w n constitution, our R e a s o n leads us to the knowledge of this certain and evident truth, that there is an eternal, most powerful, and most knowing being; w h i c h , whether a n y one will please to call God, it matters not. T h e thing is evident, and from this idea duly considered, will easily be deduced all those other attributes, w h i c h w e ought to ascribe to this eternal being" ( i v , x , 6 ) . " T h e thing is evident," says L o c k e . I n another passage he says that " 'Tis as certain, that there is a G o d , as that the opposite angles, m a d e by the intersection of two straight lines, are equal" (i,iv, 1 6 ) , adding that " T h e r e was never a n y rational creature, that set himself sincerely to examine the truth of these propositions, that could fail to assent to them" (i,iv, 1 6 ) . L o c k e readily acknowledged that not all h u m a n beings h a v e set themselves sincerely to examine the a r g u m e n t in question. Y e t he found the suggestion implausible that a whole people might fail to h a v e knowledge of G o d ' s existence: "the visible marks of extraordinary wisdom and power, a p p e a r so plainly in all the works of the creation, that a rational creature, w h o will but seriously reflect on them, cannot miss the discovery of a Deity . . . it seems stranger to me, that a whole nation of men should be a n y w h e r e found so brutish, as to w a n t the notion of a G o d ; than they should be without a n y notion of numbers, or fire" (i,iv,q). O n c e again, then: F a i t h is a species of belief, not a species of F a i t h is the correlate of revelation. F a i t h consists of knowledge. believing things on the ground that they h a v e been revealed by G o d , rather than knowing them on the g r o u n d of some demonstration (the assumption being that it cannot be demonstrated that G o d has revealed 107
revelation, but he that clearly comprehends the whole deduction, and sees the evidence of the demonstration, wherein the existence of an intelligent being . . . is scientifically proved; there are, I fear, but few Christians among illiterate people, to look no farther" (Works 111,290-1). "" In his Second Vindication of the Reasonableness of Christianity, Locke says that " T o prevent this calumny, I, in more places than one, distinguished between faith, in a strict sense, as it is a bare assent to any proposition, and that which is called evangelical faith, in a larger sense of the word; which comprehends under it something more than a bare simple assent." T h e n , after citing some passages from Reasonableness, he adds: " B y these, and more, the like passages in my book, my meaning is so evident, that nobody, but an unmasker, would have said, that when I spoke of believing, as a bare speculative assent to any proposition, as true, I affirmed that was all that was required of a Christian for justification: though that in the strict sense of the word, is all that is done in believing." W h a t is needed for justification is "not a bare idle speculation, a bare notional persuasion of any truth whatsoever, floating in our brains; but an active principle of life, a faith working by love and obedience" (Works v i , 2 8 6 ) .

so-and-so). L e t us be clear that it is not the proposition that God has revealed P w h i c h is the object of> faith (unless one believes it to have been revealed that P has been revealed - see i v , x v i i i , 6 ) . R a t h e r it is P itself, the proposition one believes to h a v e been revealed by G o d , that is the object of faith. O n the other hand, one cannot identify faith by picking out propositions of a certain sort and then saying that faith is simply the a c c e p t a n c e of those propositions; for the very
same
proposition m a y be both known and taken on faith. (Not, however, simultaneously b y the same person. A person cannot simultaneously k n o w something and believe it on the basis of revelation; awareness will overwhelm f a i t h .

)
W e must distinguish two types of revelation. In original revelation an impression "is m a d e immediately by G o d , on the mind of" the person (iv,xviii,3).
109
Traditional
revelation, b y contrast, occurs when someone
communicates to another w h a t has been originally revealed to himself or herself or someone else. Faith, in response to this latter type of revelation, consists of accepting, as revealed by G o d , w h a t that person communicates as h a v i n g been (originally) revealed to s o m e o n e . '

W e can know intuitively that w h a t e v e r G o d reveals is true; w e can "perceive" it. " W h a t e v e r G o d hath revealed is certainly true; no d o u b t can be m a d e of it" ( i v , x v i i i , i o ) . L o c k e never considers the possibility that G o d might offer to us for our belief things w h i c h , though strictly speaking not true, nonetheless serve to guide us well on the paths of life. H e just takes it as necessarily true that if G o d reveals 1
P, then P is t r u e . " B u t that G o d did in fact reveal something on some '"" "But however it he called light and seeing; I suppose, it is at most but belief, and assurance: and the proposition taken for a revelation is not such, as they know, to be true, but take to be true. For where a proposition is known to be true, revelation is needless: and it is hard to conceive how there can be a revelation to any one of what he knows already. If therefore it be a proposition which they are persuaded but do not know, to be true, whatever they may call it, it is not seeing, but believing. F'or there are two ways, whereby truth comes into the mind, wholly distinct, so that one is not the other. W h a t I see I know to be so by the evidence of the thing itself: what I believe I take to be so upon the testimony of another" (Essay i v , x i x , i o ) . 1 0 8

In his paraphrases of St. Paul's epistles, Locke several times over says that Paul, for example, was a recipient of original revelation - Works v n , 3 0 - 1 , 3 4 , 4 3 2 . t h e "impression" of which Locke speaks in explaining original revelation is presumably the belief. But if the belief is produced immediately in one by G o d , then, so it would seem, one is not accepting it on the ground that it has been revealed by G o d . T h u s it appears that Locke's definition of "faith," when combined with his account of original revelation, yields the result that the believer's response to original revelation is not a case of faith.
" ' In A n Answer to R e m a r k s upon an Essay concerning H u m a n Understanding, Locke angrily remarks that "anyone who appears among Christians, m a y be well ashamed of his name, when he raises such a doubt as this, viz. whether an infinitely powerful and wise being be veracious or no; unless falsehood be in such reputation with this gentleman, that he concludes lying to be no mark of weakness and folly" (Works 1 1 1 , 1 8 7 ) .

P can never be something known. S p e a k i n g of
Christianity, L o c k e says to one of his opponents that if you mean, in speaking of faith as knowledge, that the true religion may be known with the certainty of knowledge properly so called; I ask you farther, whether that true religion be to be known by the light of nature, or needed a divine revelation to discover it? If you say, as I suppose you will, the latter; then I ask whether the making out of that to be a divine revelation, depends not upon particular matters of fact, whereof you were no eye-witness but were done many ages before you were born? and if so, by what principles of science they can be known to any man now living." (A Third Letter for Toleration; Works v , 4 2 4 ) 1 1 2
It is because w e c a n never know that God has revealed P that our acceptance of P itself, on the ground that it has been revealed by G o d , is never knowledge (or the accompaniment of knowledge). "Whatsoever truth w e come to the clear discovery of, from the knowledge and contemplation of our o w n ideas, will a l w a y s be certainer for us, than those w h i c h are conveyed to us by traditional revelation. F o r the knowledge, w e have, that this revelation c a m e at first from G o d , can never be so sure, as the knowledge w e have from the clear and distinct perception of the agreement, or disagreement of our own ideas" 3

parent who gives the child advice which, though not "strictly speaking true," is nonetheless helpful, is not lying*. T h e passage continues: "we neither think that G o d requires, nor has given us faculties capable of knowing in this world several of those truths, which arc to be believed to salvation." In this passage, Locke speaks of the knowledge that G o d revealed something, as he does in two other passages in Essay iv,xviii,4~5: "our assurance can be no greater, than our knowledge is, that it is a revelation from G o d . " "Since the whole strength of the certainty depends upon our knowledge, that G o d revealed it . . ." Possibly these are just slips of the pen. I think it more likely, however, that they are to be read in the light of this comment in one of the letters to Stillingfleet: " I think it is possible to be certain upon the testimony of G o d . . . where I know that it is the testimony of G o d ; because in such a case, that testimony is capable not only to make me believe, but, i l l consider it right, to make me know the things to be so; and so I may be certain. For the veracity of God is as capable of making mc know a proposition to be true, as any other w a y of proof can be; and therefore I do not in such a case barely believe, but know such a proposition to be true, and attain certainty" (Works 1 1 1 , 2 8 1 ) . 1 think that we are to read this passage as if it continued thus: However, though anyone who knows that something is the testimony of God knows also that it is true, one can never know that something is the testimony of God.

revealed by G o d , w e must appraise the probability on satisfactory evidence of the proposition that God has revealed P. O n l y if this is more p r o b a b l e than not on such evidence are w e entitled to believe P itself— unless, of course, w e h a v e independent reason for accepting P. L o c k e makes clear that he is not insisting that w e need independent evidence in favor of P — in favor of the content of the purported revelation - to be justified in accepting it. Q u i t e to the contrary: T h e very genius of revelation is that, by this means, G o d can present to us for our belief things w h i c h the unaided use of our faculties has not entitled us to believe. W h a t is required is not satisfactory independent evidence in favor of P, but satisfactory evidence in favor of the proposition that God has revealed
P.
It should not be overlooked, however, that on Locke's view a good deal of the content of revelation lies within the reach of our unaided natural faculties. In The Reasonableness
of Christianity
he tries to show
that this is the case for Christian revelation, not only for w h a t it teaches us concerning our moral duties, but even for w h a t it teaches us concerning w h a t is required for salvation. T h e book, says L o c k e , was addressed mainly to d e i s t s ,
114
"designed . . . chiefly for those w h o were
not yet thoroughly, or firmly, Christians, proposing to work on those, w h o either wholly disbelieved, or doubted of the truth of the Christian religion" ( A V i n d i c a t i o n of the Reasonableness; Works v i , i 6 4 ) . His goal in writing it was to "convince . . . men of the mission of J e s u s Christ, make them . . . see the truth, simplicity, and reasonableness, of w h a t he himself taught, and required to be believed by his followers." If this were accomplished, one "need not d o u b t . . . such converts will not lay b y the scriptures, but b y a constant reading and study of them get all the light they can from this divine revelation, and nourish themselves up in the words of faith" (vi, The

Locke stales in the Reasonableness, and emphasizes repeatedly in the several Vindications, that he is discussing what Jesus (and the N e w Testament writers) teach as necessary for being a Christian; he is not discussing what Christians ought to believe. A s to the latter: they ought to believe whatever they, on reflection, believe that G o d has revealed. " T h o u g h all divine revelation requires the obedience of faith, yet every truth of inspired scriptures is not one of those that by the law of faith is required to be explicitly believed to justification . . . Those are fundamentals which it is not enough not to disbelieve; everyone is required actually to assent to them. But any other proposition contained in the Scripture, which G o d has not thus made a necessary part of the law of faith (without an actual assent to which, he will not allow anyone to be a believer) a man may be ignorant of without hazarding his Works v i , i 5 6 ) . Cf., in the various salvation by a delect in his faith" (Reasonableness; Vindications, Works vt, i 7 6 , 2 2 7 - 3 6 , 3 0 6 - 7 , 3 2 0 - 1 , 3 5 5 - 7 , 4 0 7 - 8 .

He holds, in fact, that they are infallible: "All that is contained in the inspired writings, is all of divine authority, must all be allowed for such, and received for divine and infallible truth, by every subject of Christ's kingdom, i.e. every Christian" ( W o r k s , v i , ^ 6 ) . F o r infallibility, see also ibid., 3 1 3 ; and Essay m , i x , 2 3 . A s suggested by the passage just quoted, it was because Locke viewed the Scripture writers as inspired by God that he viewed their writings as infallibly true. It is much less clear what he regarded as the connection between inspiration and revelation. It appears to me, however, that he regarded the content of any writing inspired by G o d as revealed by G o d . T h u s he seems to have regarded the N e w Testament throughout as the inspiredly infallible record of original revelation (i.e., revelation to the writer), with some of this inspiredly infallible record being, in turn, a report of traditional revelation (i.e., a report of revelation to someone other than the writer, e.g., to Jesus). Locke seems to assume that Christians do, or should, agree with him on this. A n d thus he draws the conclusion that Christians are obligated to believe all the claims of the N e w Testament writers - or rather, everything that they on reflection believe those writers to have claimed. T o do otherwise would be to dishonor G o d : " . . . the inspired writings of the holy scriptures. E v e r y part of it is [God's] word, and ought, every part of it, to be believed by every christian m a n " (Works v i , 3 5 1 ) . T h e N e w Testament is all "of divine authority, one part as much as another. A n d , in this sense, all the divine truths in the inspired writings are fundamental, and necessary to be believed" (vt, 3 4 9 ) . " A n d thus all the scripture of the N e w 'testament, given by divine inspiration, is matter of faith, and necessary to be believed by all Christians, to whom it is proposed" (vi, 3 2 1 ) . A s to its being the obligation of Christians to believe all that they, on serious reflection, believe that the N e w Testament writers claimed, rather than all that they did in fact claim, see especially A Second Vindication, in Works vi, 3 9 0 - 3 , where Locke's example of the general point is this: W h a t e v e r a Christian on serious reflection takes to be the import of Christ's words, "this is my body" and "this is my blood," that is what he ought to believe.

I f a n y proposition (self-evidently) contradicts something of which one j u d g e s oneself to h a v e intuitive
(or demonstrative)
knowledge, one must reject the proposal that G o d has revealed that proposition. "Since no evidence of our faculties b y w h i c h w e receive such revelations can exceed, if equal, the certainty of our intuitive knowledge, we can never receive for a truth a n y t h i n g that is directly contrary to our clear and distinct knowledge . . . no proposition can be received for divine revelation, or obtain the assent due to all such, if it be contradictory to our clear intuitive knowledge, because this would be to subvert the principles and foundations
of all
knowledge,
evidence, and assent whatsoever" ( i v , x v i i i , 5 ) . W h a t , then, about the case in which, though the content of the purported revelation does not contradict w h a t one judges oneself to know, nonetheless it is improbable on evidence w h i c h one judges to be satisfactory? M o r e specifically, suppose that one judges the proposition that God has revealed P to be probable on satisfactory evidence, whereas '"'
This is the content: G o d , "by the light of reason, revealed to all mankind, who would make use ol that light, that he was good and merciful. T h e same spark of the divine nature and knowledge in man, which making him a man, showed him the law he was under, as a man; showed him also the w a y of atoning the merciful, kind, compassionate A u t h o r and Father of him and his being, when he had transgressed that law. He that made use of this candle of the Lord, so far as to lind what was his duly, could not miss to find also the w a y to reconciliation and forgiveness, when he had failed of his duty . . . T h e law is the eternal, immutable standard of right. A n d a part of that law is, that a man should forgive, not only his children, bul his enemies, upon their repentance, asking pardon, and amendment. A n d therefore he could not doubt that the author of this law, and G o d of patience and consolation, w h o is rich in mercy, would forgive his frail offspring, if they acknowledged their faults, disapproved the iniquity of their transgressions, begged his pardon, and resolved in earnest, for the future, to conform their actions to this rule, which they owned to be just and right. T h i s w a y of reconciliation, this hope of atonement, the light of nature revealed to them: and the revelation of the gospel, having said nothing to the contrary" (Reasonableness; Works vi, 1 3 3 ) . T h e "new covenant" simply adds to this "old covenant": "These two, faith and repentance, i.e. believing Jesus to be the Messiah, and a good life, are the indispensable conditions of the new covenant" (ibid., 1 0 5 ) .

one j u d g e s P itself to be i m p r o b a b l e on satisfactory independent evidence. Is one then somehow to w e i g h u p the probability of the proposition that God has revealed P against the improbability of P itself, and go with the stronger (remembering that to determine the former, one must consider both the evidence for the proposition that one is confronted with an occurrence of revelation, and the evidence for the proposition that one is correctly interpreting the content of that purported occurrence)? T h o u g h L o c k e is far from lucid on this matter, I think his a n s w e r is Y e s - as indeed, in his system, it should h a v e been. H e says that "since G o d in giving us the light of R e a s o n has not thereby tied u p his o w n hands from affording us, when he thinks fit, the light of revelation in a n y of those matters, wherein our natural faculties are able to give a probable determination, revelation, where G o d has been pleased to give it, must carry it, against the probable conjectures of R e a s o n " (iv,xviii,8; cf. i v , x v i i i , g ) . T h e r e is one more connection between content and presentation: O n e is not to believe P with a firmness in excess of that with which one In the case of faith, "our is entitled to believe that God has revealed P. assent can be rationally no higher than the evidence of its being a revelation, and that this is the m e a n i n g of the expressions it is delivered in. I f the evidence of its being a revelation, or that this is its true sense be only on p r o b a b l e proofs, our assent can reach no higher than an assurance or diffidence, arising from the more, or less a p p a r e n t probability of the proofs" (iv,xvi, 1 4 ) . 119

A n d w h a t , finally, is L o c k e willing to accept as evidence for the occurrence of revelation? T h e inner experience of the enthusiasts will not do. W h a t will? L o c k e gives the matter l a m e n t a b l y short shrift; nonetheless, his answer is clear: miracles. 1 1 9
A n d that, says Locke, is sufficient for salvation: "though bare belief always includes some degrees of uncertainly, yet it does not therefore necessarily include any degree of wavering; the evidently strong probability may as steadily determine the man to assent to the truth, or make him take the proposition for true, and act accordingly, as knowledge makes them see or be certain that it is true. A n d he that doth so, as to truths revealed in the scripture, will show his faith by his works; and has, for aught I can see, all the faith necessary to a Christian, and required to salvation" (Second R e p l y to the Bishop of Worcester; Works 111,299).

A n d as for biblical revelation, Locke insisted that there is no special "biblical hermencutic." He says to Stillingfleet that he reads "the holy scripture with a full assurance, that all it delivers is true: and though this be a submission to the writings of those inspired authors, which I neither have nor can have, for those of any other men; yet I use the same w a y to interpret to myself the sense of that book, thai I do of any other" (Works 1 1 1 , 3 4 1 ) . In the Preface to his paraphrases of the epistles of St. Paul, Locke spells out his interpretative principles. A very helpful discussion of the role of Locke's thought in the origins of modern biblical criticism is H . G . Reventlow, The Authority of the Bible and the Rise of the Modern World (Philadelphia, Fortress Press, 1 9 8 5 ) .

W e see the holy men of old, w h o h a d revelation from G o d , had something else besides that internal light of assurance in their o w n minds, to testify to them, that it was from G o d . T h e y were not left to their own persuasions alone, that those persuasions were from G o d ; but had outward signs to convince them of the author of those revelations. A n d when they were to convince others, they had a power given them to justify the truth of their commission from heaven; and by visible signs to assert the divine authority of the message they were sent with.

i n v a r i a b l y he takes it as obvious that
the miracle reported confirms that the person performing the miracle, or in one w a y or another the subject of the miracle, is the recipient of divine revelation. F o r example, " T h e evidence of our Savior's mission from heaven is so great, in the multitude of miracles he did before all sorts of people, that w h a t he delivered cannot but be received as the oracles of G o d , and unquestionable verity; for the miracles he did were so ordered by the divine providence and wisdom, that they never were, nor could be, denied by a n y of the enemies or opposers of Christianity" (Reasonableness;

vi,i35).
T h i s view, traditional though it be, that miracles are evidence for divine revelation, bristles with problems. T o mention just one: H o w m u c h of w h a t a person believes has been divinely revealed to him is confirmed as h a v i n g been divinely revealed to him by the miraculous sign of which he is the recipient? C o r r e s p o n d i n g l y , how m u c h of w h a t a person claims to h a v e been divinely revealed to him is confirmed as having been divinely revealed to him by his performance of a miracle? T o these problems, L o c k e never addressed himself. Neither did he address with care the question H u m e raised: U n d e r w h a t circumstances, if a n y , are w e permitted to accept testimony to the effect
that a miracle has occurred? H e remarks that
"the
credibility and attestation of the report is all that is of moment, when miracles done by others in other places are the a r g u m e n t prevails"
( T h i r d L e t t e r for Toleration;

it is

Locke's discussion of the nature of miracles, which does not here concern us, is to be found in his posthumously published " A Discourse of Miracles." A p p a r e n t l y he believed that the occurrence of miracles continued into, at least, the early church; see his T h i r d Letter for Toleration; Works v,448ff.

that these writings w e r e inspired by God. A n d that evidence will itself h a v e to consist of miracles performed b y these writers. T h u s L o c k e speaks of "an undoubted testimony that miracles w e r e done b y the first publishers of [the g o s p e l ] " (v, 4 4 3 ) ; and he says not only that the gospel is still a c c o m p a n i e d by this testimony, but that this is all that most readers of it h a v e ever had: "all those, w h o were not eye-witnesses of miracles done in their presence, it is plain had no other miracles than w e have; that is, upon report; and it is p r o b a b l e not so m a n y , nor so well attested as w e h a v e " ( v , 4 4 3 ) . Is L o c k e suggesting that it is probable, on extra-biblical
evidence,
that those w h o wrote the biblical books worked miracles; and is he suggesting that w e are to believe on this basis, and with a certain tempered level of confidence,
that they were inspired, and hence
infallible? I think not. Instead his thought appears to be that the relevant evidence for the inspired status of their writings is offered by the biblical writers in their books; in their books they report the miraculous evidence w h i c h confirms that they were recipients of revelation. O f course, that invites the question whether, say, Moses w a s the author of those books w h i c h report revelations received by Moses along with their miraculous confirmations - as indeed it invites the question
whether, if these books were written by Moses, he
correctly reported his experience. L o c k e , in one passage, himself recognizes the relevance of these questions:
the history of the deluge is conveyed to us by writings, which had their original from revelation: and yet nobody, I think, will say, he has as certain and clear a knowledge of the flood, as Noah that saw it; or that he himself would have had, had he then been alive, and seen it. For he has no greater an assurance than that of his senses, that it is writ in the book supposed writ by Moses inspired: But he has not so great an assurance, that Moses writ that book, as if he had seen Moses write it. So that the assurance of its being a revelation, is less still than the assurance of his senses. (iv,xviii,4) O n e final point: L o c k e mentions one circumstance in w h i c h it is, if not exactly permissible, nonetheless harmless, to believe that G o d has revealed something to one, even though one lacks the evidence of miracles; namely, the circumstance of the content of the purported personal revelation already h a v i n g been revealed in Scripture. I n that circumstance, one can be assured that, w h e t h e r or not one has received a revelation, the content of the purported revelation belongs to w h a t G o d has revealed (iv,xix, 1 6 ) !

Morality
Locke's presentation of his thoughts on moral obligation is considerably more scattered than that of his thoughts on "revealed" and " n a t u r a l " religion. Nonetheless, the structure of his thought is relatively c l e a r . A n d as to the importance of the topic, he never w a v e r e d : "since our faculties are not fitted to penetrate into the internal fabric and real essences of bodies; but yet plainly discover to us the being of a G o d , and the knowledge of ourselves, enough to lead us into a full and clear discovery of our duty, and great concernment, it will become us, as rational creatures, to employ those faculties w e h a v e about w h a t they are most adapted to, and follow the direction of nature, where it seems to point us out the w a y . F o r 'tis rational to conclude, that our proper employment lies in those enquiries, and in that sort of knowledge, which is most suited to our natural capacities, and carries in it our greatest interest, i.e., the condition of our eternal estate. H e n c e I think I m a y conclude, that morality is the proper science, and business of mankind in general; ( w h o are both concerned, and fitted to search out their (iv,xii,ii). Summum Bonum)" 123
" A m o n g s t the simple ideas, which w e receive both from sensation and reflection, pain and pleasure are two very considerable ones," says L o c k e ( n , x x , i ) . H e goes on to say that things "are good or evil, only in reference to pleasure or pain. T h a t we call good, w h i c h is apt to cause or increase pleasure, or diminish pain in us; or else to procure, or preserve us the possession of a n y other good, or absence of any evil. A n d on the contrary, we n a m e that evil, w h i c h is apt to produce or increase a n y pain or diminish a n y pleasure in us; or else to procure us any evil, or deprive us of any good" ( n , x x , 2 ) . Locke's subsequent discussion makes clear that the words " p a i n " and "pleasure" are misleading as names for the phenomena he has in mind. H e is taking note of the fundamental fact that m u c h of our experience is "phenomenologically valorized" - some of w h a t w e experience, w e like; some, we dislike. T h a t this is different from the pleasure/pain contrast is easily seen by observing, for example, that persons sometimes like pain. L o c k e himself says that " B y pleasure and pain . . . I m

he
is better thought of as standing in the long classical tradition of eudaimonism.
H e himself, on a n u m b e r of occasions, uses "happiness"
to express w h a t he has in m i n d .
1 2 4
H a v i n g given his account of good and evil, L o c k e then takes note of w h a t he calls "uneasiness": the state of lacking something that one believes would be pleasant, when
that state itself is unpleasant
( n , x x , 6 ) . T h i s , he says, is the same as desire
(n,xxi,3i).
1 2 5
uneasiness, or desire, is w h a t causes the passions ( I I , X X , 3 - I 8 )
And and
determines the will (n,xxi,2o,- 3 9 ) - though, as L o c k e sees clearly, one may
desire something without choosing it, even when free to do so
(n,xxi.4o,46ff.). T h o u g h the concepts of good and evil enter into Locke's analysis of moral obligation, nonetheless the concept of moral obligation is under stood by him as fundamentally different from that of good. O b l i g a t i o n is w h a t is required by divine law. A law in general is a certain sort of rule for v o l u n t a r y action (n,xxviii,4 5 ) ; specifically, a rule for voluntary action is a l a w if someone w h o wills that the rule be followed and has the right to c o m m a n d that it be followed attaches sanctions and

In ii,xxviii,ia, Locke considers the objection that he is forgetting his own concept of a law when he says that social customs m a y have the status of law. His reply is interesting: " I f anyone shall imagine, that I have forgot my own notion of a law, when I make the law, whereby men j u d g e of virtue and vice to be nothing else, but the consent of private men, who have not authority enough to make a law: Especially wanting that, which is so necessary, and essential to a law, a power to enforce it: I think, I may say, that he, who imagines commendation and disgrace, not to be strong motives on men to accomodate themselves to the opinions and rules of those, with whom they converse seems little skilled in the nature, or history of mankind: the greatest part whereof he shall find to govern themselves chiefly, if not solely, by the law of fashion." W h a t then follows is an impressive discussion of the force of social approval and disapproval. 1 2 6

T h u s " w h a t d u t y is, cannot be understood without a law; nor a l a w be known, or supposed without a l a w m a k e r , or without r e w a r d and punishment" (i,iii, 1 2 ) . Specifically, d u t y is w h a t is required b y divine law. Locke's theory of moral obligation is a divine c o m m a n d theory though it is i m p o r t a n t to add that the c o m m a n d s are those of a necessarily loving G o d whose goal is the happiness of all his h u m a n creatures.
128
" T h a t G o d has given a rule w h e r e b y men should govern
themselves, I think there is n o b o d y so brutish as to d e n y , " says L o c k e . " H e has a right to do it, w e are his creatures: H e has goodness and wisdom to direct our actions to that which is best: and he has p o w e r to enforce it by r e w a r d s and punishments,
of infinite
weight
and
duration, in another life: for nobody can take us out of his hands. T h i s is the only true touchstone of moral rectitude" (u,xxviii,8). T h e sanctions attached to divine law are of course goods and evils, "pleasures" and "pains." A n d since divine law is the determinant of moral obligation, w e can call those goods and evils, moral goods and moral evils - without, however, identifying moral good with obligation.
129
" [ D i v i n e l a w ] is the only true touchstone of moral rectitude; and by c o m p a r i n g them to this law, it is, that men j u d g e of the
most
considerable moral good or evil of their actions; that is, whether as duties, or sins, they are like to procure them happiness, or misery, from the hands of the A l m i g h t y " (n,xxviii,8). "Morally
good and evil then, is only
the conformity or disagreement of our voluntary actions to some law, w h e r e b y good or evil is d r a w n on us, from the will and p o w e r of the l a w m a k e r ; w h i c h good and evil, pleasure or pain, attending our observance, or breach of the l a w , by the decree of the l a w m a k e r , is that w e call reward

Kor a contemporary analogue, developed with a much more sophisticated attention to the nature of meaning than one iinds in Locke, see Robert M .

" " T h a t which has very much confounded men about the will and its determinations has been the confounding of the notion of moral rectitude and giving it the name of moral good. T h e pleasure that a man takes in any action or expects as a consequence of it is indeed a good in itself able and proper to move the will, but the moral rectitude of it considered barely in itself is not good or evil nor in any w a y moves the will but as pleasure and pain either accompanies the action itself or is looked on to be a consequence of it. W h i c h is evident from the punishments and rewards which G o d has annexed to moral rectitude or pravity as proper motives by the will which would be needless if moral rectitude were itself good and moral pravity evil."

B u t though the prospect of securing happiness or avoiding unhappiness is a l w a y s w h a t motivates us, it remains the case that w h a t determines our obligations is divine law, not utility: "if the source and origin of all this law is the care and preservation of oneself, virtue would seem to be not so m u c h man's duty as his convenience, nor will a n y t h i n g be good except w h a t is useful to him; and the observance of this law would be not so m u c h our duty a n d obligation, to w h i c h w e are bound by nature, as a privilege and an a d v a n t a g e , to w h i c h w e are led by e x p e d i e n c y . "
130
It seems clear that a law is a determinant of obligation only if the person laying d o w n the law has the right to c o m m a n d obedience of those to w h o m
the l a w applies; otherwise
the issuance
of
the
c o m m a n d is simply an exercise of power. In his early (unpublished) work Essays on the Law of Nature,
L o c k e repeatedly and emphatically
acknowledges the point; and argues that G o d has such a right. T o understand w h e n c e some "bond of law takes its origin," says L o c k e , "we must understand that no one can oblige or bind us to do anything, unless he has right and p o w e r over us; and indeed, when he c o m m a n d s w h a t he wishes should be done and w h a t should not be done, he only makes use of his right. H e n c e that bond derives from the lordship and c o m m a n d which a n y superior has over us and our actions, and in so far as w e are subject to another w e are so far under an obligation. But that bond constrains us to discharge our liability, and the liability is twofold: First, a liability to p a y dutiful obedience . . . S e c o n d l y , a liability to punishment, w h i c h arises from a failure to p a y dutiful o b e d i e n c e . "
131
T h a t G o d , in particular, has the right to
lay d o w n c o m m a n d s for our actions follows, says L o c k e , from the fact that w e are G o d ' s creatures. In the Essays
L o c k e states the point
brutally: "for w h o will deny that the clay is subject to the potter's will, and that a piece of pottery can be shattered by the same hand by which it has been formed?" (p. 1 5 5 ) . In the Second Treatise of Government he states it somewhat more delicately: "men being all the workmanship of one omnipotent, and infinitely wise maker; all the servants of one sovereign master, sent into the world by his order, and about his business; they are his property, whose w o r k m a n s h i p they are, m a d e to

T h e right to which L o c k e is here appealing appears to be the right to dispose of one's property as one wishes; w e are G o d ' s property. B u t h o w , in Locke's system, are w e to understand the status of such a right? Earlier in the Essays
L o c k e had remarked that "right is
g r o u n d e d in the fact that w e h a v e the free use of a thing, whereas l a w is w h a t enjoins or forbids the doing of a thing" (p. 1 1 1 ) . O n this understanding, for one to h a v e a right to d o so-and-so is for the relevant laws of obligation to permit one to do so-and-so. B u t obviously G o d ' s right to c o m m a n d obedience of us cannot be understood as consisting in G o d ' s being permitted to do so by the laws of obligation, if the
laws of obligation
are just G o d ' s laws. L o c k e offers
alternative analysis, h o w e v e r ;
132
no
and I fail to see w h a t alternative
analysis he could offer. T h e r e is, here, a deep fissure in Locke's theory. It is important to realize that the very same rule for action which occurs in divine law might also o c c u r in civil and social law; when that is the case, and the question is raised w h y the rule should be followed, one might reply by appealing to a n y one of the statuses that it has all of t h e m .
133
or to
F u r t h e r m o r e , people m a y disagree on the status of some
rule for action; one person m a y think it belongs to divine law; another, only to civil or social law. T o deny that a rule for action has the status of divine law is tantamount, on Locke's view, to denying that it specifies a 1
moral obligation; '"
those w h o deny that there are any divine laws
1:12
Sec, lor example, iv,xiii,3, where Locke just asserts lhal whoever has "the idea of an intelligent, hut frail and weak heing, made by and depending on another, who is eternal, omnipotent, perfectly wise and good, will as certainly know that man is to honour, fear and obey C o d , as that the sun shines when he sees it. f o r if he hath but the ideas of two such beings in his mind, and will turn his thoughts that w a y , and consider them, he will as certainly find that the inferior, finite, and dependent, is under an obligation to obey the supreme and infinite, as he is certain to find, that three, (bur, and seven, are less than fifteen, if he will consider, and compute those numbers." Perhaps so! But there is no w a y in which Locke can account for the fact here "perceived."
1 3 3
A n d it is because, if a rule for action is a law, there is always something (of one or the other of three sorts) which accounts for its being a law, that " 1 think, there cannot any one moral rule be proposed whereof a man may not justly demand a reason . . . should that most unshaken rule of morality, and foundation of all social virtue, That one should do as he would be done unto, be proposed to one, who never heard it before, but yet is of capacity to understand its meaning; might he not without any absurdity ask a reason why? A n d were not he that proposed it, bound to make out the truth and reasonableness of it to him? S o that the truth of all these moral rules, plainly depends upon some other antecedent to them, and from which they must be deduced" (i,iii,4). Locke regards this as a reason for concluding that moral laws are not innate in us. Cf. Essay i,iii,6: "the true ground of morality; which can only be the will and law of a G o d , who sees men in the dark, has in his hand rewards and punishments, and power enough to call to account the proudest offender."

That men should keep their compacts, is certainly a great and undeniable rule in morality: But yet, if a Christian, who has the view of happiness and misery in another life, be asked why a man must keep his word, he will give this as a reason: Because God, who has the power of eternal life and death, requires it of us. But if an Hobbist be asked why; he will answer: Because the public requires it, and the Leviathan will punish you, if you do not. And if one of the old heathen philosophers had been asked, he would have answered: Because it was dishonest, below the dignity of a man, and opposite to virtue, the highest perfection of human nature, to do otherwise. Hence naturally flows the great variety of opinions, concerning moral rules, which are to be found amongst men, according to the different sorts of happiness, they have a prospect of, or propose to themselves . . . But yet I think it must be allowed, that several moral rules may receive, from mankind, a very general approbation, without either knowing, or admitting the true ground of morality; which can only be the will and law of a God. (i,iii,5 and 6 ) 1 3 5
T h a t there are civil and social laws is obvious. L o c k e took it as scarcely less obvious that there is divine law - "that l a w w h i c h G o d has set to the actions of men, whether promulgated to them b y the light of nature, or the voice of revelation" ( n , x x v i i i , 8 ) . Both reason and revelation tell us that w e h a v e obligations to G o d . A n d as to how, from the other side, w e come to believe that some rule for action is an obligation, i.e., that it is something G o d requires of us, Locke's answer is that w e come to believe this in m a n y w a y s : by believing our teachers on their sayso, by accepting revelation, and so on: I doubt not, but without being written on their hearts, many men, may, by the same way that they come to the knowledge of other things come to assent to several moral rules, and be convinced of their obligation. Others also may come to be of the same mind, from their education, company, and customs of their country; which, persuasion however got, will serve to set conscience on work, which is nothing else, but our own opinion or judgment of the moral rectitude or pravity of our own actions.

T h e interesting question, though, is whether w e can know — k n o w in Locke's strict sense of " k n o w " - that some rule for action is a moral obligation. C a n w e know, about some rule for action, that it is a l a w of G o d for us? Locke's a n s w e r is Y e s : W e can, in principle, arrive at a knowledge of m a n y , if not all, of our moral obligations. W e do not, indeed, come into the world knowing them; w h a t is innate in us is not the knowledge of moral obligations but the c a p a c i t y for c o m i n g to know moral obligations: " [ T ] h e goodness of G o d . . . hath furnished m a n with those faculties, w h i c h will serve for the sufficient discovery of all things requisite to the end of such a being" (i,iv, 1 2 ) . T h e faculties required include our c a p a c i t y for demonstration; moral obligations cannot be known intuitively. T h e y are not self-evident. " [ M j o r a l principles require reasoning and discourse and some exercise of the mind, to discover the certainty of their truth. T h e y lie not open as natural characters ingraven on the mind . . . these moral rules are c a p a b l e of demonstration: and therefore it is our o w n faults, if w e come not to a certain knowledge of them" ( i , i i i , i ) . 1;i6
L o c k e consistently used the expression " l a w of nature" to mean a l a w of moral obligation which can in principle be known by R e a s o n . A c c o r d i n g l y , summarizing his discussion of how authentic knowledge of moral obligation is attainable, he says that " T h e r e is a great deal of difference between an innate law, and a l a w of nature; between something imprinted on our minds in their very original, and something that w e being ignorant of m a y attain to the knowlege of, by the use and due application of our natural faculties. A n d I think they equally forsake the truth, w h o running into the contrary extremes, either affirm an innate law, or deny that there is a law, knowable by the light of nature; i.e., without the help of positive revelation" (i,iii, 1 3 ) . T o say that something is a law of nature, meaning by "law of nature" w h a t L o c k e means by it, is not to imply that e v e r y b o d y , or indeed, anybody, knows it to be a law of obligation. Locke's repeated references in the Second Treatise to laws of nature do not carry the implication that laws of nature are, by a consensus gentium, k n o w n to be laws of obligation. It is true that G o d ' s laws for our lives, to be genuine laws for us, must be promulgated - m a d e available to us b y R e a s o n or revelation. B u t w e m a y correctly believe of some rule for action that it is Cf. a passage already cited in another context: "Another reason that makes me doubt of any innate practical principles, is, that 1 think, there cannot any one moral rule be proposed, whereof a man m a y not justly demand a reason: which would be perfectly ridiculous and absurd if they were innate, or so much as self-evident" (i,iii,4; my italics).

T h e existence of G o d , says L o c k e , "is so m a n y w a y s manifest, and the obedience w e o w e him, so congruous to the light of R e a s o n , that a great part of m a n k i n d give testimony to the l a w of nature: B u t yet I think it must be allowed, that several moral rules, m a y receive, from mankind, a v e r y general a p p r o b a t i o n , without either k n o w i n g , or admitting the true g r o u n d of morality; w h i c h can only be the will and l a w of a G o d , w h o sees men in the dark, has in his h a n d rewards and punishments, and p o w e r enough to call to account the proudest offender" (i,iii,6). T h o u g h he never doubted that some if not all moral obligations can in principle be demonstrated, and thereby known, L o c k e readily conceded that almost nothing had yet been done on this project; few of the requisite demonstrations had yet been offered. Possibly it is just "too hard a task for unassisted reason to establish morality, in all its parts, upon its true foundations, with a clear and convincing light" (Reasonableness; Works v i , 1 3 9 ) . O r perhaps the reason that "the knowledge of morality, by mere natural light . . . has but a slow progress" is not to be found in the fact that it is beyond the unaided ability of h u m a n beings to accomplish it as a whole, but is rather "to be found in men's necessities, passions, vices, and mistaken interests, which turn their thoughts another w a y . . . the designing leaders, as well as the following herd, find it not to their purpose to employ m u c h of their meditations this w a y " (vi, 1 4 0 ) . W h a t e v e r "the cause, it is plain in fact that h u m a n reason, unassisted, failed men in its great and proper business of morality. It never, from unquestionable principles, b y clear deductions, m a d e out an entire b o d y of the law of nature'''' (vi,i4o). 1 : 1 7
K
" O n e of the points Locke makes in his discussion of these issues in Reasonableness is that sometimes one's abilities arc such that one is able to construct a proof by following suggestions, but not able to construct that proof without having those suggestions. S o too, one m a y be able to follow a proof, without having been able, even with hints and suggestions, to construct it oneself. Either w a y , one is able, solely by the use of reason, to come to know the conclusion, namely, by following the demonstration; even though one is not able, without suggestions, or even with suggestions, to construct the proof oneself It was Locke's view that Scripture provides us with suggestions for how to construct a scientia of morality; he speculates that without those suggestions, it might have been impossible. W h e n Locke defines a "law of nature" as an obligation which can in principle be known by unaided Reason, I suspect that he does not have in mind anything at all about the conditions for discovering the relevant demonstrations; he means only to say that there exist (whether any human being has ever been aware of them or not) arguments for those laws of obligation which human beings are capable of "perceiving" to be demonstrative.

eventually, h o w e v e r , he g a v e up and suppressed w h a t he had written, remarking, in a letter to his y o u n g friend W i l l i a m M o l y n e u x , that " I thought I saw that morality might be demonstratively m a d e out; yet whether I am able so to make it out, is another q u e s t i o n .

This
passage has sometimes been interpreted as expressing uncertainty as to whether a scientia of morality with a n y significant amplitude really is possible. I think that reading it within the context of the letter as a whole makes clear that that is not h o w it should be interpreted; nor does a n y other passage in L o c k e , of which I a m a w a r e , w a r r a n t the conclusion that he had serious doubts on the matter. In the letter, he is simply expressing the doubt that he himself has the intellectual powers necessary for the task. I m m e d i a t e l y after the sentence quoted he says that " E v e r y o n e could not h a v e demonstrated w h a t M r . N e w t o n ' s book hath shown to be demonstrable." W e can glean, from various sources, evidence of Locke's intimations as to how the demonstration would h a v e to go. S t a r t i n g from intuitive knowledge of one's o w n existence, coupled perhaps with sensitive knowledge of the existence of material objects (and other persons?), it would proceed to offer a proof of the existence of a C r e a t o r of these entities. Proofs concerning the nature of G o d would then be offered, from which the conclusion would be d r a w n that G o d issues rules for the action of G o d ' s rational c r e a t u r e s ,
139
and that they h a v e the
obligation to obey those rules. F r o m the nature of G o d w e would then infer that these c o m m a n d s are for the happiness of G o d ' s c r e a t u r e s . '™

This Sovereign L a w M a k e r w h o has set rules and bounds to the actions of men is god their maker whose existence we have already proved. T h e next thing then to show is that there are certain rules, certain dictates which it is his will all men should conform their actions to, and that this will of his is sufficiently promulgated and made known to all mankind." T h e divine law, "in its true notion, is not so much the limitation as the direction of a free and intelligent agent to his proper interest, and prescribes no farther than is for the general good of those under that law" (Second Treatise, §57; Works i v , 3 7 o ) .

141
and w e w o u l d attempt,
rather early, to derive the principle that one should do as he would be done unto, since it is "the most unshaken rule of morality, and foundation of all social virtue" ( i , i i , 4 ) .
142
In short, a "rational ethics" would be
constructed by reflecting on w h a t a good G o d , w h o cares about the happiness of each of G o d ' s h u m a n creatures, would ask of them. In a striking anticipation of K a n t ' s opposition to utilitarian ethics, L o c k e holds that it will turn out that there are some duties such that it is impossible to be a h u m a n being and not h a v e those duties. In the Essays on the Law of Nature he remarks that " h u m a n nature must needs be c h a n g e d before this law can be either altered or annulled . . . this law does not depend on an unstable a n d c h a n g e a b l e will, but on the eternal order of things . . . A n d this is not because nature or G o d (as I should say more correctly) could not h a v e created m a n differently. R a t h e r , the cause is that, since m a n has been m a d e such as he is, equipped with reason and his other faculties and destined for this mode of life, there necessarily result from his inborn constitution some definite duties for him, which cannot be other than they are. In fact it seems to me to follow just as necessarily from the nature of m a n that, if he is a m a n , he is bound to love and worship G o d and also to fulfil other things a p p r o p r i a t e to the rational nature, as it follows from the nature of a triangle that, if it is a triangle, its three angles are equal to two right angles . . . natural law stands and falls together with the nature of m a n as it is at present" ( 1 9 9 2 0 1 ) .

Cf. O i l m a n ' s summary of the main elements of Locke's thought here: " I n Locke's theory, then, the will of C o d is the form of the law of nature; it makes the directives of morality to be laws binding mankind. H u m a n nature provides the necessary terminative element in the law of nature, for what G o d wills men to do is somehow incorporated in the w a y he has m a d e them. Locke's theory of moral obligation m a y be summed up thus: God's will is necessary and sufficient to place men under an obligation; the facts of human nature arc necessary and sufficient to delimit the obligations men are placed under" [Locke's Moral Philosophy, p. 4 2 ) . Various commentators (e.g., fully, in "Governing Conduct") argue that Locke was a voluntarist in his moral theory. I do not doubt that Locke thought G o d could have created human beings whose happiness was achieved somewhat differently from how ours is achieved - though Locke was impressed by the variety of the w a y s in which actual h u m a n beings do find their happiness (see esp. n , x x i , 5 4 - 5 , 6 5 ) . Nonetheless, it is clear that L o c k e thought it to be necessarily true that the rules for action which G o d lays down as laws to h u m a n beings are laws which promote human happiness. (He does not, with any consistency, state the goal any more precisely than that.) H e says that "the duties of [the divine] law, arising from the constitution of [ G o d ' s ] very nature, are of eternal obligation; nor can it be taken a w a y or dispensed with without changing the nature of things" [Reasonableness; Works vt, 1 1 2 ) ; and "that G o d himself cannot choose what is not good; the freedom of the almighty hinders not his being determined by w h a t is best" (n,xxi,49).

Rationality

In three different places in Book i v of the Essay, L o c k e speaks of his vision of a scientia of moral obligation. O n e of those can serve as a sketch of the picture I h a v e d r a w n : T h e idea of a supreme being, infinite in power, goodness, and wisdom, whose workmanship we are, and on whom we depend; and the idea of ourselves, as understanding, rational beings, being such as are clear in us, would, I suppose, if duly considered, and pursued, afford such foundations of our duty and rules of action, as might place morality amongst the sciences capable of demonstration: wherein I doubt not, but from self-evident propositions, by necessary consequences, as incontestable as those in mathematics, the measures of right and wrong might be made out. (iv,iii, 18) T h e other two passages, however, give a v e r y different impression of how the scientia of moral obligation would be structured. O n e of them goes like this: This gave me the confidence to advance that conjecture . . . that morality is capable of demonstration, as well as mathematics. For the ideas that ethics are conversant about, being all real essences, and such as I imagine have a discoverable connexion and agreement one with another; so far as we can find their habitudes and relations, so far we shall be possessed of certain, real, and general truths: and I doubt not, but if a right method were taken, a great part of morality might be made out with that clearness, that could leave, to a considering man, no more reason to doubt, than he could have to doubt of the truth of propositions in mathematics, which have been demonstrated to him. (iv,xii,8)"" A s examples of propositions w h i c h will o c c u r in this projected scientia, L o c k e cites Where there is no property, there is no injustice, and No government allows absolute liberty (iv,iii, 1 8 ; perhaps, in i v , i v , 8 , he intends Murder deserves death as another e x a m p l e ) . This alternative description of the project of a scientia of moral obligation is obviously very different from the previous description. R a t h e r than constructing a long proof, m o v i n g from one's own existence, to G o d ' s existence, to G o d ' s nature, to our nature, to w h a t yields us happiness, thence to rules of obligation, one simply offers necessary, analytic and synthetic, truths pertaining to moral concepts - constructing demonstrations of those necessary truths w h e n e v e r one does not intuitively "perceive" them to be true. T h e analogue to pure 1 4 3
Cf. iv,iv,7: "moral knowledge is as capable of real certainty, as mathematics. For certainty being but the perception of the agreement, or disagreement of our ideas; and demonstration nothing but the perception of such agreement, by the intervention of other ideas, or mediums, our moral ideas, as well as mathematical, being archetypes themselves, and so adequate, and complete ideas, all the agreement, or disagreement, which we shall find in them, will produce real knowledge, as well as in mathematical figures."

mathematics, as L o c k e understood that, is obvious. After all, says L o c k e , moral concepts are like m a t h e m a t i c a l ones in being "mixed modes"; being such, they are "combinations of several ideas, that the mind of man has arbitrarily put together, without reference to a n y archetypes . . . A c c o r d i n g l y , since the precise signification of the names of mixed modes, or w h i c h is all one, the real essence of each species, is to be known, they being not of nature's, but man's making, it is a great negligence and perverseness, to discourse of moral things with uncertainty and obscurity" ( m , x i , i 5 ) . I know of no place in w h i c h L o c k e explains the discrepency between these two w a y s of describing the project of a scientia
of
morality; so we are left to speculate. M y speculation is that L o c k e saw two different projects in the region: call them the theis tic project and the archetypal project.
T h e archetypal project is entirely hypothetical: I f
there were a situation in w h i c h there was no property, that would be a situation in w h i c h there was no injustice; if there were a situation of absolute liberty, that would be a situation in w h i c h there was no government; if some killing constituted m u r d e r , that killing would merit the death penalty. E x t r e m e l y interesting things might turn u p in this project, just as extremely interesting things turn up in pure mathematics. B u t from the a r c h e t y p a l project w e do not learn w h a t are in fact our moral obligations - that is, w h a t G o d does in fact require of us. T o learn that where there is no property, there is no injustice is not to learn w h a t G o d requires and forbids of us with respect to property - nor, indeed, is it to learn whether there is a n y property. T o learn that m u r d e r deserves death is not to learn w h a t sort of penalty G o d requires for killing a fellow h u m a n being
nor is it
to learn whether there h a v e ever been a n y killings which are murders. T h e full picture, then, is that the archetypal project is not only of interest in its o w n right but an indispensable ancillary to the more comprehensive theistic project. V a r i o u s abstract relations a m o n g moral concepts are m a p p e d out in the archetypal project; in the theistic project, those concepts are used and their inter-relationships appealed to in the course of establishing our obligations. A n d to show that some action is obligatory is perforce to m a k e clear a motivation for performing i t .

145
H e offered another excuse as well:
T h e existence of the Christian revelation has taken a w a y the urgency. R e s p o n d i n g to W i l l i a m M o l y n e u x ' request that he write a treatise on morals, L o c k e said that " D i d the world w a n t a rule, I confess there could be no w o r k so necessary, nor so c o m m e n d a b l e . B u t the Gospel contains so perfect a b o d y of ethics, that reason m a y be excused from that inquiry, since she m a y find man's d u t y clearer and easier in revelation than in herself."
146
A n y o n e w h o wishes his rules to pass for
authentic laws must show that either he builds his doctrine upon principles of reason, self-evident in themselves, and that he deduces all the parts of it from thence, by clear and evident demonstration; or must show his commission from heaven, that he comes with authority from God to deliver his will and commands to the world. In the former way nobody that I know before our Saviour's time, ever did or went about to give us a morality. It is true, there is a law of nature; but who is there that ever did, or undertook to give it us all entire, as a law; no more nor no less than what was contained in, and had the obligation of, that law? Whoever made out all the parts of it, put them together, and showed the world their obligation? Where was there any such code, that mankind might have recourse to as their unerring rule, before our Saviour's time? If there was not, it is plain there was need of one to give us such a morality; such a law, which might be the sure guide of those who had a desire to go right; and, if they had a mind, need not mistake their duty; but might be certain when they had performed, when failed, in it. Such a law of morality Jesus Christ hath given in the New Testament; but by the latter of these ways, by revelation, we have from him a full and sufficient rule for our direction, and conformable to that of reason. But the truth and obligation of its precepts have their force, and are put past doubt to us, by the evidence of his mission. (Reasonableness; Works vi, 1 4 2 - 3 ) Christian

C o l m a n , ibid., pp. 1 6 9 70, remarks, correctly, I think, that " T h e r e are in fact two parts to Locke's envisaged demonstration of morality. T h e first concerns the existence of a moral law which imposes an obligation on all mankind. C a r r y i n g this through involves a proof of God's existence (sketched in the fourth book of the Essays and set out in detail at iv,x in the Essay), a proof that He does intend us to conform our actions to a law, and an analysis of the concept of obligation. Given the existence of the law, the second part of the demonstration is to make out its content, or determine beyond doubt the correct measures of right and wrong. Locke would consider the first of these parts to have been substantially completed in the Essay. It was this second to which his friend William Molyneux and others urged Locke to turn his hand."

"" A central thesis in C . B. MaePherson's interpretation of Locke's political theory (The Political Theory of Possessive Individualism [Oxford, Oxford University Press, paperback, 1 9 6 4 ] ) is that "Locke assumed in his own society a class differential in rationality which left the labouring class incapable of a fully rational life, i.e. incapable of ordering their lives by the law of nature or reason" (p. 2 3 2 ) . M a c P h e r s o n goes on to argue that Locke assumed a differential of natural rights corresponding to this differential of rationality. In support of his claim that Locke assumed a differential of rationality between the laboring class and the leisured property class, MacPherson cites those passages in which Locke says that the members of the laboring class barely have time to "raise their thoughts above" the demands of subsistence. M a c P h e r s o n then interprets the point of passages in Reasonableness, such as the one I have just quoted in the text above, as "that without supernatural sanctions the labouring class is incapable of following a rationalist ethic. H e only wants the sanctions made clearer. T h e simple articles he recommends are not moral rules, they are articles of faith. T h e y are to be believed. Belief in them is all that is necessary, for such belief converts

It goes without saying that few people h a v e found Locke's proposal for a true science of ethics plausible. His application to morality of the practice he proposed has in that w a y experienced a fate strikingly different from his application to revealed religion of the practice. T h o u g h in this latter area, too, w h a t w e h a v e from Locke's h a n d is more project than accomplishment,
nonetheless his

model for the relation of faith and reason has proved enormously compelling a m o n g the intelligentsia of the modern W e s t .

A t the v e r y heart of Locke's model of the responsible believer was a preachment, an exhortation: W e ought so to discipline ourselves that, for those propositions of suflicient "concernment" to us, w e take R e a s o n as our guide. T h e " w e " here is E v e r y m a n : everyone w h o has the moral rules of the Gospel into binding commands . . . T h e greatest part of mankind, Locke concludes, cannot be left to the guidance ofthe law of nature or law of reason; they are not capable of d r a w i n g rules of conduct from it" (p. 2 2 5 ) . T h i s is a deep, albeit subtle, misinterpretation of Locke. T h e fact that Scripture attaches divine sanctions to the law of G o d is nothing peculiar to Scripture. Locke's view is that a rulr for action is a law specifying obligations jusl in case il is God's will for our lives and has divine sanctions attached. Such a law may be either a law of nature, or promulgated in Scripture, or believed on probabilistic evidence, or handed down by tradition, or all of these. Il is a law of nature if it can be demonstrated by "unaided" Reason. Further, Locke thinks that even the best philosophers have come far short of developing a complete science of morality by unaided Reason, let alone developing one which is widely intelligible and convincing. Scripture in its completeness and its persuasiveness is superior to what anyone has been able to achieve. T h u s Scripture is not just advantageous for the laboring class; it is advantageous for all human beings. Further, believing Scripture is itself to be done in accord with the dictates of Reason. But lastly, what about Locke's supposed assumption of a differential rationality and dilfcrential set of natural rights? Locke did indeed think that if one has no access to the moral law, one has no obligations and fewer natural rights; he thought that infants and small children and " m a d " persons were in that position. But there are carious modes of access to that law: demonstration, entitled belief which makes no appeal to Scripture, entitled belief which does make appeal to Scripture, riach of these makes use of Reason in its own w a y . A n d Locke thought that one or the other mode was available "even" to the members of the laboring class. W h a t they do not have time for is the following out of complicated demonstrations, and the pursuit of "natural philosophy." Further, nobody whatsoever has the time to conduct his or her understanding aright with respect to more than a fraction of his or her beliefs. In short, one cannot arrive at the conclusion that Locke regarded members of the laboring class as having fewer natural rights from the premises that M a c P h c r s o n appeals to. Infants and mad persons do; it's not at all clear that those w h o have to spend almost all their time working do. Perhaps I should add that I lind Locke's smug and arrogant attitude toward the laboring class thoroughly offensive. M y point has been that MacPherson's attempt to show that Locke grounds that attitude in his overall system fails.

the answer: People did not conduct their understandings in the right w a y - not in science, not in religion, not in politics, not in ethics, not even in practical affairs. In the opening of the small book w h i c h L o c k e published as a supplement to his Essay and which he called The Conduct of the Understanding,
he classifies under three headings the
principal "miscarriages that men are guilty of in reference to their R e a s o n " (§3; Works 1 1 , 3 2 5 ) . T o these three he shortly (§6) adds a fourth.
149
O n e of the c o m m o n miscarriages is shortsightedness.
W e tend to
"see but one side of the matter: our views are not extended to all that has a connection with it" (§3; 1 1 , 3 2 6 ) . " T h e faculty of reasoning seldom or never deceives those w h o trust to it, its consequences from w h a t it builds on are evident and certain, but that which it oftenest, if not only, misleads us in, is, that the principles from which w e conclude, the grounds upon w h i c h w e bottom our reasoning, are but a part; something is left out w h i c h should go into the reckoning to make it just and e x a c t " (§3; 1 1 , 3 2 6 - 7 ) .
In some people
this
shortsightedness is like a disease. " T h e y canton out to themselves a little Goshen in the intellectual world, where light shines, and, as they conclude, d a y blesses them; but the rest of that vast e x p a n s u m they give up to night and darkness, and so avoid coming near it" (§3;
u.327)-
A second miscarriage in the use of Reason is permitting passion
to
play a role in the conduct of one's understanding. W e h a v e met this miscarriage earlier, in our discussion of the wounds of the mind: Instead of cultivating "indifference" to everything but truth in the conduct of their understandings, people allow passions to play their distorting role. T h e y "put passion in the place of R e a s o n , and . . . neither use their o w n , nor hearken to other people's, R e a s o n a n y Later in the book, after discussing tile importance of practice and habituation, Locke introduces and discusses a rather long list of vices which hinder the ability and inclination to apply the practice which he is recommending - tossing in here and there mention of somevirtues necessary to the practice. " T h e r e are, he says, "several weaknesses and defects in the understanding, either from the natural temper of the mind, or ill habits taken up, which hinder it in its progress to knowledge. O f these there are as m a n y , possibly, to be found, if the mind were thoroughly studied, as there are diseases of the body, each whereof clogs and disables the understanding to some degree, and therefore deserves to be looked after and cured. I shall set down some few to excite men, especially those who make knowledge their business, to look into themselves and observe whether they do not indulge some weaknesses . . . in the management of their intellectual faculty, which is prejudicial to them in the search of truth (Conduct, § 1 2 ; Works 1 1 , 3 4 9 ) . 11

farther than it suits their humor, interest, or p a r t y " (§3; 1 1 , 3 2 6 ) . A third miscarriage is also familiar: O u r education leads us to take as unquestionably true certain principles,
and to j u d g e the truth of
other things by reference to these - this in spite of the fact that they "are not self-evident, and very often not so m u c h as true" (§6; 1 1 , 3 3 3 ) • But
the first miscarriage w h i c h L o c k e cites is the one w h i c h has
been a constant presence throughout our discussion: the influence of tradition,
especially in the form of partisanship. I t is the miscarriage
"of those w h o seldom reason at all, but do and think according to the e x a m p l e of others, whether parents, neighbors, ministers, or w h o else they are pleased to h a v e an implicit faith in, for the saving of themselves the pains and trouble of thinking and examining for themselves" (§3; 1 1 , 3 2 6 ) . Earlier I called attention to the fact that between the medievals and Locke something happened which has proved of fateful significance for us in the modern West, and by now for the rest of the world: W h e r e a s tradition had once been regarded and treated as a repository of wisdom, L o c k e u n w a v e r i n g l y saw it as a source of error and vice. The
Essay
and the Conduct are an unrelenting attack on tradition.
T r a d i t i o n is u p against the wall. W o r d s are all too often the enemy of good philosophy (m,x; i v , i i i , 3 o ) . T r a d i t i o n is a l w a y s the enemy of doing our best. T o do our best, w e must liberate ourselves from the grip of unexamined tradition and allegiance to unquestioned authority, coolly assessing the tenability of every tradition and authority from outside all traditions and authorities. T h e counterpart to Locke's attack on tradition w a s his celebration of the sovereign individual who,
freed from distorting passion and principle, sits in j u d g m e n t on
tradition, "inquiring directly into the nature of the thing itself, without minding the opinions of others" (Conduct, § 3 5 ; Works 1 1 , 3 8 2 ) . In Locke's epistemological thought, as well as his political thought, the sovereign individual occupies center stage. W e would m a k e greater progress, he says, in the discovery of rational and contemplative knowledge, if we sought it in the fountain, in the consideration of things themselves; and made use rather of our own thoughts, than other men's to find it. For, I think, we may as rationally hope to see with other men's eyes, as to know by other men's understandings. So much as we ourselves consider and comprehend of truth and reason, so much we possess of real and true knowledge. The floating of other men's opinions in our brains makes us not one jot the more knowing,

though they h a p p e n to be true. W h a t in them was science, is in us but opiniatrety, whilst w e give up our assent only to reverend names, and do not, as they did, employ our own R e a s o n to understand those truths, which gave them reputation. (i,iv,23) L o c k e uses this same point to defend the thesis w h i c h he propounds in the Conduct that "there is no part wherein the understanding needs a more careful and w a r y conduct than in the use of books" (§24; 1 1 , 3 6 4 ) . Books, after all, are a m o n g the principal bearers of tradition. "Books and reading are looked upon to be the great helps of the understanding and instruments of k n o w l e d g e " (§24; 1 1 , 3 6 4 ) . T h e y may well be that. B u t if the reader believes w h a t the writer says on the writer's untested sayso, he will a l w a y s believe it in a w a y inferior to that of the writer. I f the writer knew, the reader merely believes. If the writer's belief was supported by strong evidence, that of the reader is supported by rather w e a k evidence. T h e mistake here is, that it is usually supposed that by reading, the author's knowledge is transferred into the reader's understanding; and so it is, but not by bare reading, but by reading and understanding what he writ. W h e r e b y I mean not barely comprehending what is affirmed or denied in each proposition . . . but to see and follow the train of his reasonings, observe the strength and clearness of their connection, and e x a m i n e upon what they bottom . . . K n o w i n g is seeing; and if it be so, it is madness to persuade ourselves that we do so by another man's eyes . . . Until we ourselves see it with our own eyes, and perceive it by our own understandings, we are as much in the dark, and as void of knowledge as before, let us believe any learned author as much as we will. Euclid and Archimedes are allowed to be knowing, and to have demonstrated what they say: and yet whoever shall read over their writings without perceiving the connection of their proofs, and seeing what they show, though he m a y understand all their words, yet he is not the more knowing. H e m a y believe, indeed, but does not know what they say. (Conduct, §24; 11,365; see also §§20, 24) L o c k e was not under the illusion, however, that his writings would by

accomplish
the goal of reforming how his
fellow
countrymen and w o m e n conducted their understandings; neither did he think that a bevy of similarly hortatory books would accomplish this goal. S u c h books can present rules for the direction of the mind, a c c o m p a n i e d by defenses of the rules and exhortations to follow the rules, along with advice concerning their application. B u t " N o b o d y is m a d e anything by hearing of rules, or laying them up in his m e m o r y . . . and you m a y as well hope to make a good painter or musician,

Would you have a man write or paint, dance or fence well, or perform any other manual operation dexterously and with ease, let him have never so much vigor and activity, suppleness and address, naturally, yet nobody expects this from him unless he has been used to it, and has employed time and pains in fashioning and forming his hand or outward parts to these motions. Just so it is in the mind: would you have a man reason well, you must use him to it betimes; exercise his mind in observing the connection of ideas, and following them in train. . . . we are born to be, if we please, rational creatures, but it is use and exercise only that makes us so. (Conduct, §6; 11,337) And
how do w e gain the practice required for the right conduct of
the understanding? B y education.
Referring to the four miscarriages
that w e h a v e noted L o c k e says that " T h e s e are the c o m m o n and most general miscarriages w h i c h I think men should avoid or rectify in a right conduct of their understandings, and should be particularly taken care of in education. T h e business whereof,
in respect of
knowledge, is not, as I think, to perfect a learner in all or any one of the sciences, but to give his mind that freedom, that disposition, and those habits that m a y enable him to attain any part of knowledge he shall a p p l y himself to, or stand in need of, in the future course of his life" (Conduct, § 1 2 ; 1 1 , 3 4 8 ) . I observed, in our discussion of Locke's wounds of the mind, that his recommendations for the cure of such w o u n d s seemed curiously bland compared
to their seriousness.
T h e r e is nothing
in
L o c k e like
Descartes's T h e r a p y of D o u b t . B u t now at last it becomes clear that we were looking in the w r o n g place. W e were expecting L o c k e to urge on us some therapeutic regimen. T h e r e is, indeed, a bit of that. But mainly the counterpart in L o c k e to Descartes's T h e r a p y of D o u b t is not a similar regimen for curing the mind's wounds, but an educational p r o g r a m inculcating the habits required for rightly conducting the understanding. Locke's Thoughts on Education
should be seen as the
counterpart to those passages in Descartes where Descartes outlines,

proposed therapeutic medicine, L o c k e , preventative. T h e new educational practice is to be aimed at children, since adults w h o h a v e been mis-educated are usually too set in their w a y s for much to be done about them - another reason, perhaps, w h y L o c k e says so little, when discussing
the w o u n d s of the
mind,
concerning the cure for the wounds. M u c h better to prevent the wounds than try to cure them: the reason why they do not make use of better and surer principles, is because they cannot: But this inability proceeds not from want of natural parts . . . but for want of use and exercise. Few men are from their youth accustomed to strict reasoning, and to trace the dependence of any truth in a long train of consequences to its remote principles, and to observe its connection; and he that by frequent practice has not been used to this employment of his understanding, it is no more wonder that he should not, when he is grown into years, be able to bring his mind to it, than that he should not be on a sudden able to grave or design, dance on the ropes, or write a good hand, who has never practised either of them . . . What then! can grown men never be improved or enlarged in their understandings? I say not so; but this I think 1 may say, that it will not be done without industry and application, which will require more time and pains than grown men, settled in their course of life, will allow to it, and therefore very seldom is done. (Conduct, §6; ".335) J u s t as education in the right conduct of the understanding will focus especially on children, so, conversely, the education of children will focus mainly on such education. O t h e r habits must be acquired than those necessary for rightly conducting the understanding. B u t these latter arc fundamental: " D u e care being had to keep the body in strength and vigor, so that it m a y be able to obey and execute the orders of the mind; the next and principal business is, to set the mind right, that on all occasions it m a y be disposed to consent to nothing, but w h a t m a y be suitable to the dignity and excellency of a rational creature" (Some Thoughts, 3 1 ; Works v t n , 2 6 - 7 ) .

I h a v e contended that Locke's philosophy w a s , by inner intent a n d by mode of presentation, a public philosophy, calling people release themselves
from the grip of tradition and passion,
to
from
inculcated principles and shortsightedness, urging on them a p r o g r a m of self-mastery, and more importantly, of child education. T h o u g h he does not often emphasize the point, L o c k e realizes that this p u b l i c philosophy implies a social vision. A d e q u a t e inquiry w h i c h is at all extensive requires leisure; and within the space of leisure, it requires peace, humanity, and friendship.
W h a t , then, about those poor wretches,
of w h o m L o c k e spoke so smugly and coolly, whose entire lives must be spent in m a n u a l d r u d g e r y ? A r e they not to enjoy the social Utopia of peace, h u m a n i t y , and friendship? L o c k e thought that even they h a d sufficient time, on S u n d a y s and holidays, to reflect on elementary matters of morality and religion; so p r e s u m a b l y for them those d a y s are to be d a y s of peace, h u m a n i t y , and friendship. The point is that for all of us there are clearings in the thicket of our practical duties where w e can concern ourselves with truth alone. F o r some, those clearings are c r a m p e d ; for certain leisured members of society, they are expansive. B u t whether large or small, for life in those clearings peace, h u m a n i t y , and friendship are required: Since therefore it is unavoidable to the greatest part of men, if not all, to have several opinions, without certain and indubitable proofs of their truth; and it carries too great an imputation of ignorance, lightness, or folly, for men to quit and renounce their former tenets, presently upon the offer of an argument, which they cannot immediately answer, and show the insufficiency of it: it would, me thinks become all men to maintain peace, and the common offices of humanity, and friendship, in the diversity of opinions, since we cannot reasonably expect, that any one should readily and obsequiously quit his own opinion, and embrace ours with a blind resignation to an authority, which the understanding of man acknowledges not. For however it may often mistake, it can own no other guide but Reason, nor blindly submit to the will and dictates of another. (iv,xvi,4) 151
O u r expectations must be modest, h o w e v e r , even for a society w h i c h supports a sizeable g r o u p of leisured persons and creates the social conditions 1 5 1
necessary for satisfactory inquiry and reflection.

ancient and medieval ideal of insight by R e a s o n into the essences of things must be renounced; "our faculties are not fitted to penetrate into the internal fabric and real essences of bodies." Instead
of
affording us insight into the reality surrounding us, R e a s o n mainly offers us the guidance of probability for our m a k i n g and doing in the midst of that reality. I think I m a y conclude, says L o c k e ,
"that
morality is the proper science, and business of mankind in general; ( w h o are both concerned, and fitted to search out their Bonum,)."
Summum
T h a t is w h a t holds for h u m a n i t y in general. A n d as for
leisured people:
"several arts, conversant about several parts of
nature, are the lot and private talent of particular men, for the c o m m o n use of h u m a n e life, and their own particular subsistence in this w o r l d . " It is to the " c o m m o n use of h u m a n e life," and Y e s , to the admiration of nature's C r e a t o r , that the new natural
philosophy
makes its principal contribution. " I readily agree" says L o c k e , that "the contemplation of [ G o d ' s ] works gives us occasion to admire, revere, and glorify their author: and if rightly directed, m a y be of greater benefit
to mankind,
than
the monuments
of e x e m p l a r y
c h a r i t y . " " A l l that I would s a y , " he adds, "is, that we should not be too forwardly possessed with the opinion, or expectation of knowledge, where it is not to be h a d " (iv,xii, 1 1 - 1 2 ) . O u r study of nature is not for the sake of contemplation. O u r study of nature is in the service of our praxis and our poiesis, of our doing and our making; its results seldom reach beyond probability. I close by noting a feature of Locke's writing which has perplexed a good m a n y of his readers. Several times over w e h a v e noted Locke's conviction, shared by the R o y a l Society g r o u p in general, that words as w e receive them are the enemy of good philosophy. "Students, being lost in the great wood of w o r d s , " do not know where they are. O n l y if w e put words aside and set before our mind's eye the very ideas themselves can we avoid "that perplexity, puddering, and confusion, which has so much
hindered
men's
progress in other
parts of
knowledge" (iv,iii,3o). W h a t is worst in words, if understanding is our goal, is figurative speech. F i g u r a t i v e speech has its place in discourse meant to give "pleasure and delight"; it is out of place, and worse than out of place obstructive — in discourse meant to inform or instruct:
Since wit and fancy finds easier entertainment in the world, than dry truth and real knowledge, figurative speeches, and allusion in language, will

hardly be admitted, as an imperfection or abuse of it. I confess, in discourses, where we seek rather pleasure and delight, than information and improvement, such ornaments as are borrowed from them, can scarce pass for faults. But yet, if we would speak of things as they are, we must allow, that all the art of rhetoric, besides order and clearness, all the artificial and figurative application of words eloquence hath invented, are for nothing else but to insinuate wrong ideas, move the passions, and thereby mislead the judgment; and so indeed are perfect cheat: and therefore however laudable or allowable oratory may render them in harangues and popular addresses, they are certainly, in all discourses that pretend to inform or instruct, wholly to be avoided. (m,x,34) It is ironic that the rhetorical p o w e r of this h a r a n g u e by L o c k e against figurative speech should in good measure depend on its vivid metaphors: "dry truth," "insinuate w r o n g ideas," "move the passions," "perfect cheat." A n d in general, the persuasive p o w e r of Locke's writing depends heavily on his extraordinary gift for metaphor: "the white tablet of the m i n d , " "the state of nature," "the candle of the L o r d , " "cantoning a little Goshen for themselves in the intellectual w o r l d . " H o w are w e to explain the dissonance: harangues against m e t a p h o r by one of the greatest creators of m e t a p h o r in the English philosophical tradition? W a s L o c k e oblivious to the fact that he was using metaphors? H o w , then, to explain such extraordinary oblivi ousness? W a s his goal in writing to give pleasure and delight rather than inform and instruct? A n answer, of sorts, is to be found in Conduct of the Understanding,
§32:
T h o u g h philosophers must bring themselves to the point where they think without metaphor, they m a y nonetheless speak metaphorically: But it is one thing to think right, and another thing to know the right way to lay our thoughts before others with advantage and clearness, be they right or wrong. Well-chosen similes, metaphors, and allegories, with method and order, do this the best of anything, because being taken from objects already known, and familiar to the understanding, they are conceived as fast as spoken; and the correspondence being concluded, the thing they are brought to explain and eludicate is thought to be understood too. Thus fancy [i.e., imagination] passes for knowledge, and what is prettily said is mistaken for solid. I say not this to decry metaphor, or with design to take away that ornament of speech; my business here is not with rhetoricians and orators, but with philosophers and lovers of truth; to whom I would beg leave to give this one rule whereby to try whether, in the application of their thoughts to anything for the improvement of their knowledge, they do in truth comprehend the matter before them really such as it is in itself. The way to discover this is to observe whether, in the laying it before themselves or
i 8 5
Rationality

others, they make use only of borrowed representations, and ideas foreign to the things, which are applied to it by w a y of accommodation, as bearing some proportion or imagined likeness to the subject under consideration. Figured and metaphorical expressions do well to illustrate more abstruse and unfamiliar ideas which the mind is not yet thoroughly accustomed to; but then they must be made use of to illustrate ideas that we already have, not to paint to us those which we yet have not. Such borrowed and allusive ideas m a y follow real and solid truth, to set it off w h e n found; but must by no means be set in its place, and taken for it. If all our search has yet reached no farther than simile and metaphor, we m a y assure ourselves we rather fancy than know, and have not yet penetrated into the inside and reality of the thing. (11,378) Locke's i m a g e of his o w n work, which he wishes us to share, is that first there w a s the non-pictorial thought, then there was the pictorial writing. T h e truth is that the thought itself is pictorial and metaphoric. T h e mind, says L o c k e , "perceives" agreements and disagreements a m o n g its ideas, those agreements and disagreements
themselves
being "luminous." T h e s e metaphors of perception and luminosity are deeper than a n y others in L o c k e . I h a v e m a d e no attempt in m y discussion to eliminate them. F o r the pictures are not decorative features of Locke's presentation of his thought but an indispensable feature of the thought itself. L o c k e thought in pictures and metaphors. W e all do. It w a s one of his gifts to h a v e done his thinking in pictures which proved fruitful for himself and compelling for others.

Hume's attack: why implementing Locke's practice is not always doing one's best
A s I proceeded d o w n the path of trying to discern w h a t Locke was getting at in his discussion concerning the g o v e r n a n c e of belief and to uncover his motives for trying to get at it, I h a v e offered, at various points, w h a t is perhaps more a "rational reconstruction" than an interpretation, strictly speaking. W h e n doing so, I h a v e often brought twentieth-century discussions of the same issues into the conversation. A n d every now and then I h a v e stopped to ask w h e t h e r some claim or assumption that L o c k e m a d e was true, often bringing contemporary discussions into the conversation at those points as well. Often, indeed, it was contemporary discussions which suggested the question. I h a v e considered, for e x a m p l e , whether w e h u m a n beings do in fact possess the powers of immediate awareness and of will w h i c h Locke's proposed method, or practice, presupposes. M y conclusion was that, on these matters, Locke's proposal holds u p better than a typical, late-twentieth-century, philosopher would initially h a v e supposed. H o w e v e r , m y central goal on this occasion is not so much to critique as to understand this central part of the culture of modernity. T h u s I h a v e said almost nothing, and will say nothing more, about Locke's overarching strategy of trying to cope with fractured tradition by escaping from all untested tradition and going to "the things themselves." I believe that such escape is impossible. B u t m a n y others have argued this point in recent years; on this occasion I will not add to w h a t they h a v e said. Before w e leave our g r a p p l i n g with L o c k e ' s thought I do wish, though, to appraise w h a t he says on one, absolutely central, issue. L o c k e claimed that trying one's best to get in touch with reality on some matter, and then
responding appropriately to the
results
thereof, requires trying to a p p l y his principles of evidence, appraisal, and proportionality. I wish to ask whether he w a s right about even the first step in his three-step procedure; along the w a y , some r
59

considerations will arise pertaining to the other steps as well. It w a s H u m e w h o first saw the issues here with clarity, and w h o argued with great power that for m a n y facts of several different sorts, Locke's method does not give us our best access. H u m e went for the j u g u l a r ; T h o m a s R e i d joined him for the kill. S o I propose considering the most fully developed of H u m e ' s arguments on this score: his a r g u m e n t that while inductive inference, even at its best, is not a case of applying Locke's principles, it nonetheless provides us with our best access to a wide range of facts to w h i c h Locke's method, as it turns out, gives us no access at all. I shall then a d d to H u m e ' s a r g u m e n t some comments of m y o w n . T o the fourth edition of his Essay L o c k e added a chapter w h i c h he called " O f the Association of I d e a s . " H e h a d noticed that not only persons of too m u c h self-love, but "men of fair minds, and not given up to the overweening of self-flattery," also frequently display a w o u n d i n g of the mind. In " m a n y cases one with a m a z e m e n t hears the arguings, and is astonished at the obstinacy of a w o r t h y m a n , w h o yields not to the evidence of Reason, though laid before him as clear as d a y l i g h t " ( u , x x x i i i , 2 ) . T h i s m a y rightly be called "by so harsh a n a m e as madness, when it is considered, that opposition to R e a s o n deserves that n a m e " (n,xxxiii,4). L o c k e observes that the particular w o u n d he has in mind can rightly be ascribed to education and prejudice. B u t he has come to believe, he says, that to say this is not to get to "the bottom of the disease, nor [to show] distinctly enough w h e n c e it rises, or wherein it lies" ( u , x x x i i i , 3 ) . T h e cause is that ideas acquire a connection in the mind quite other than their intrinsic agreement and disagreement.
T h e y become
associated
by custom: "ideas
that
in
themselves are not at all of kin, come to be so united in some men's minds, that 'tis v e r y hard to separate them, they a l w a y s keep in c o m p a n y , and
the one
no sooner at a n y time comes into

Locke's description of the injurious effects of custom on the mind rises to eloquence: T h a t which thus captivates their Reasons, and leads men of sincerity blindfold from common sense, will, when e x a m i n e d , be found to be what we are speaking of: some independent ideas, of no alliance to one another, are by education, custom, and the constant din of their party, so coupled in their minds, that they always a p p e a r there together, and they can no more

separate them in their thoughts, than if they were but one idea, and they operate as if they were so. This . . . is the foundation of the greatest, I had almost said, of all the errors in the world; or if it does not reach so far, it is at least the most dangerous one, since so far as it obtains, it hinders men from seeing and examining . . . This . . . confusion of two different ideas, which a customary connexion of them in their minds hath to them made in effect but one, fills their heads with false views, and their reasonings with false consequences. (n,xxxiii, 1 8 ; cf. Conduct, § 4 1 ) Confusing the association of ideas produced b y custom with the agreement and disagreement that they possess intrinsically is "a weakness to which all men are so liable," "a taint which so universally infects m a n k i n d , " and so m u c h sets "us a w r y in our actions, as well moral as natural, passions,
reasonings and notions
themselves"
(n,xxxiii,8) that extremely great care must be taken "in its prevention and c u r e " (n,xxxiii,4). W h a t H u m e showed in his frontal attack on the L o c k i a n vision w a s that the association of ideas, which L o c k e says w e must do our best to set off to the side as w e try to conduct our understanding aright, lies at the v e r y foundation of our practice of induction; and that this, in turn, is indispensable to h u m a n , and indeed animal, existence. H u m a n life rests at bottom not on R e a s o n in particular, nor insight in general, but on the association of ideas b y habit. H u m e h a d no substantial disagreements with L o c k e on the nature of knowledge and science (i.e., scientia).
T o see this, w e must begin with
an item of terminology. L o c k e grouped together all mental objects as ideas. H u m e called them all, instead, perceptions. B u t H u m e then went on to distinguish, a m o n g perceptions, those w h i c h he called impressions and those which he called ideas. W e shall not go w r o n g if we think of H u m e ' s ideas as our present-day concepts. F e w of us would n o w a d a y s accept H u m e ' s theory of concepts (taking his theory of ideas to be his theory of concepts). B u t w h a t w e would cite as examples of concepts are pretty m u c h w h a t H u m e cites as examples of ideas. N o w for the L o c k i a n i s m . T h e r e arc, says H u m e , various types of relations holding a m o n g ideas. " T h e s e relations m a y be divided into two classes: into such as depend entirely on the ideas, w h i c h w e c o m p a r e together, and such as m a y be changed without a n y c h a n g e in the ideas" ( T 6 9 ) . 1

necessarily; some, only contingently. T h o s e of the former sort "can be the objects of knowledge and certainty" ( T 7 0 ) . " A l l certainty arises," says H u m e , "from the comparison of ideas, and from the discovery of such relations as are unalterable, so long as the ideas continue the same" (T
7 9 ) . W h e n w e do h a v e knowledge of the
necessary relations a m o n g our ideas, it is because of the workings of "intuition" and "demonstration" ( 7 " 7 0 ) . H u m e thinks that necessary relations a m o n g ideas are all of one or the other of four fundamental types. A n d these four, he says, "are the foundation of science" ( T 7 3 ) . His view in the Treatise
is that only
algebra and arithmetic can "be esteemed a perfect and infallible science" ( 7 " 7 1 ) . H e explicitly argues that geometry does not qualify. C l e a r l y it is applied
geometry on w h i c h he has his eye. Perhaps he
himself eventually realized this; for in the later Enquiry Human
Understanding
Concerning
he cites geometry along with algebra and
arithmetic as a "science." It is worth quoting w h a t he says there: All the objects of human reason or enquiry may naturally be divided into two kinds, to wit, Relations of Ideas, and Mailers of Fact. O f the first kind are the sciences of Geometry, Algebra, and Arithmetic; and in short, every affirmation which is either intuitively or demonstratively certain. That the square of the hypotenuse is equal to the squares of the two sides, is a proposition which expresses a relation between these figures. That three times five is equal to the half of thirty, expresses a relation between these numbers. Propositions of this kind are discoverable by the mere operation of thought, without dependence on what is anywhere existent in the universe. Though there never were a circle or triangle in nature, the truths demonstrated by Euclid would for ever retain their certainty and evidence. (E 25) H u m e had little interest, h o w e v e r , in knowledge - less even than L o c k e . H a v i n g said that "all the objects of h u m a n reason or enquiry" are either (necessary) relations of ideas or (contingent) matters of fact, he rushes quickly from relations of ideas to matters of fact. A n d then, in turn, he quickly remarks that it is "a subject w o r t h y of curiosity, to enquire w h a t is the matter of that evidence w h i c h assures us of a n y real existence and matter of fact, beyond the present testimony of our senses, or the records of our m e m o r y " (E 2 5 ) . W h a t H u m e had in mind by "the present testimony of our senses" is, I think, w h a t in other passages he calls "impressions of sensation and reflection"; thus w h a t he proposes inquiring into is "the nature of that evidence w h i c h assures us of a n y real existence a n d matter of fact" beyond present and remembered subjective experience.

It is characteristic of h u m a n beings and animals, says H u m e , that upon perceiving an event of one type they believe that an event of some other type has occurred or is occurring or will occur. N o such belief-dispositions

the
particular belief-dispositions produced depending on the p a r t i c u l a r experience activating that basic-disposition. In short, the presence in us of inductive belief dispositions is the consequence of learning, not of being innately e n d o w e d with such dispositions. W h a t sort of experience activates that innate disposition to form these belief-dispositions? O n l y one sort, says H u m e : the experience of a correlation of spatio-temporally contiguous events. T o put it roughly: It is one's experience of a regular correlation, between spatio-temporally contiguous events of type A and of type B , w h i c h produces in one the disposition, upon perceiving an event of type A , to believe that there is or w a s or will be also an event of type B . All belief of matter of fact or real existence is derived merely from some object, present to the memory or senses, and a customary conjunction between that and some other object. O r in other words; having found in many instances, that any two kinds of objects - flame and heat, snow and cold - have always been conjoined together; if flame or snow be presented anew to the senses, the mind is carried by custom to expect heat or cold, and to believe that such a quality does exist, and will discover itself upon a nearer approach. This belief is the necessary result of placing the mind in such circumstances. It is an operation of the soul, when we are so situated, as unavoidable as to feel the passion of love, when we receive benefits, or hatred, when we meet with injuries. (E 4 6 ) 2
T h o u g h in general the correlation between A - t y p e events and B - t y p e events must h a v e been experienced a n u m b e r of times before the belief-disposition is produced, H u m e grants that in certain cases just one such experience is sufficient. F u r t h e r m o r e , he thinks that in general the more often a correlation has been experienced, 2
the
Cf. 87: "'Tis therefore by E X P E R I E N C E only, that we can infer the existence of one object from that of another. T h e nature of experience is this. W e remember to have had frequent instances of the existence of one species of objects; and also remember, that the individuals of another species of objects have always attended them, and have existence in a regular order of contiguity and succession with regard to them. Thus we remember to have seen that species of object we call flame, and to have felt that species of sensation we call heat. W e likewise call to mind their constant conjunction in all past instances."

stronger is "the impulse or tendency to the transition" ( T 1 3 0 ) ; and in turn, the stronger that impulse, the more firmly is the belief held when the belief-disposition is triggered ~ u p to, no doubt, some m a x i m a l firmness for such beliefs ( T 1 3 0 - 1 ) . W h a t happens if the correlation experienced is fairly
regular but not invariant? T h e n the belief-
disposition will be weaker, and the belief produced will be less firm, than they would h a v e been if the experienced correlation had been invariant. R o u g h l y speaking, the further from invariant the experienced correlation, the weaker the disposition and the less firm the belief. I f one has over and over experienced that nineteen out of every twenty ships which sail from a h a r b o r eventually return, then upon seeing another ship sail out of the h a r b o r , one will be quite strongly inclined to believe quite firmly that it will return ( 7 " 1 3 4 6 ° . ) . T h o u g h H u m e introduces various refinements into this general picture (cf. especially his discussion of "the probability of chances" and of "unphilosophical p r o b a b i l i t y " ) , a review of the psychological literature produced since his d a y would, of course, lead one to introduce m a n y more. Certain matters H u m e leaves obscure; for e x a m p l e , the role of belief in the formation of these belief-dispositions, and in their activation once
they h a v e been
formed. H u m e recognizes
that beliefs
are
sometimes components in the activating experience; but he offers no general theory on the matter, and does not speak consistently. O t h e r crucial matters simply escape his attention
for e x a m p l e , the fact that
an indefinite n u m b e r of distinct inductions are compatible with a n y given set of experiences. W h a t determines, then, which belief-disposition will get formed? A n d when various dispositions h a v e been formed, w h a t determines w h i c h will get activated on a given occasion? I think it can be said, however, that introducing into H u m e ' s account the necessary refinements, clarifications, and elaborations will not diminish the p o w e r of his attack on Locke's system. W e all do engage in the practice of induction. O n e c a n concede that point, without agreeing with H u m e that every disposition to believe the occurrence of some event w h i c h is activated b y experiencing the occurrence of another is produced in us by the observation of some regularity. O n e can hold that some such belief-dispositions are produced by something else in experience, even that some are innate. Neither need one accept H u m e ' s description of the nature of belief and the m a n n e r of its formation. It will be sufficient to grant that w e do engage in the practice of induction - that upon perceiving one event w e believe the occurrence of another even when w e discern no logically/ontologically

attack
necessary relation between the two, and that sometimes the mechanisms for such belief-formation work as H u m e suggests. W h a t is it that H u m e wishes to say about this practice of induction? T h e conventional interpretation has been that he wishes to say that the beliefs produced b y the practice lack "justification"; and that, derivatively, the practice itself lacks "justification." I a n H a c k i n g , for e x a m p l e , in The Emergence
of Probability,
describes H u m e as holding
that " O u r expectations are formed by custom and habit, but lack 3
justification." A n d again, "expectation about the future is unjustified." Though
H a c k i n g is certainly
one
of our
most
clear-eyed
4
and
perceptive historians, he is not, indeed, a "professional" historian of modern philosophy. B u t m a n y "professional" historians h a v e spoken the same w a y . R i c h a r d Popkin, for example, says that it w a s H u m e ' s view of ordinary matter-of-fact beliefs that they dire groundless, h a v e no ground, are unfounded,
lack justification,
h a v e no
foundation.
5
W h a t is it that H a c k i n g , Popkin, and others h a v e had in mind when they h a v e said that, on H u m e ' s view, beliefs formed b y the practice of induction lack justification? T h a t is by no means clear. O n e course to take here would be to bring more interpreters into the discussion and then to explore various possibilities as to w h a t they might mean. B u t I see no w a y of interpreting w h a t might be meant which does not conflict with one or more of four fundamental facts about H u m e ' s thought. S o rather than considering various possibilities as to w h a t H u m e ' s interpreters might mean by "justification," let us take note of these fundamental facts. First, H u m e held that once an inductive belief-disposition has been produced in us, then, if the event w h i c h activates that disposition occurs, the corresponding belief follows automatically, without the working of volition. A n d not only are inductive beliefs not formed by the will; w e cannot by acts of will prevent their formation if the belief-disposition
has been formed and the activating event occurs.
All w e can do by act of will to get rid of the belief is c h a n g e the regularities in o u r experience. S e c o n d l y , H u m e points to a continuum of degrees of "evidence," offers his o w n d e m a r c a t i o n of different g a m u t s on the continuum, and places probabilities
and (causal)
proofs on the positive end of the continuum.
T h i r d l y , H u m e speaks of just inferences - that is, in c o n t e m p o r a r y :

inferences. " T h e only connexion or relation of
objects, w h i c h can lead us beyond the immediate impressions of our m e m o r y and senses, is that of cause and effect; and that because 'tis the only one, on which w e can found a just inference from one object to another" (T 8 9 ) . A n d again, " I shall allow, if you please, that the one proposition m a y justly be inferred from the other; I know, in fact, that it a l w a y s is inferred" (E 3 4 ) . It should also be noted that after reviewing various "kinds of probability," i.e., various manifestations of our practice of induction, H u m e says that these "are received by philosophers, and allowed to be reasonable foundations of belief and opinion" ( X 1 4 3 ) .
6
A n d fourthly, H u m e says that the practice of induction "informs us of existences and objects, w h i c h w e do not see or feel" (T
74; my
italics). E l a b o r a t i n g this point, he says in another place that " H e r e , then, is a kind of pre-established h a r m o n y between the course of nature and the succession of our ideas; and though the powers and forces, by which the former is governed, be wholly unknown to us; yet our thoughts and conceptions h a v e still, w e find, gone on in the same train with the other works of nature. C u s t o m is that principle, by w h i c h this correspondence has been effected; so necessary to the subsistence of our species, and the regulation of our conduct, in every circumstance and occurrence of h u m a n life" (E 5 4 - 5 ) . ' In short, H u m e regards m a n y of the beliefs practice of induction
as h a v i n g a certain
produced by our
(positive)
degree
of
"evidence," and m a n y of our inductive inferences as just and reasonable. A n d he thinks that m u c h of the time our inductive practice m a p s or mirrors w h a t transpires in nature itself. N o w w h a t e v e r m a y be meant in saying of H u m e that on his view our inductive practice and the 6
7
I take H u m e to be hinting, in these passages, at an account of justifiedly held belief quite different from anything Locke would have affirmed. T h e clearest expressions of this account that H u m e ever gives in his published works and they are quite unclear - are to be found in Book 1, Part IV, Section iv \ Of the modern philosophy] of the Treatise, and here and there in the Dialogues concerning Natural Religion, where he speaks of the "irregular inference." W h a t is clear, in spite of the unt larily, is that il is a "proper functioning" account. In calling it this, 1 mean both to allude to the fact that it is an immediate predecessor of Reid's account, and to indicate that Alvin Planlinga's "proper functioning" theory of warrant is the most recent, and far and a w a y the most sophisticated, manifestation of a line of thought adumbrated by Hume. See Plantinga, Warrant and Proper Function (Oxford, Oxford University Press, 1 9 9 3 ) . O n the surface reading of this passage, H u m e believed that natural objects possessed causal powers. A recent defense of the thesis that the surface reading is the correct reading is G a l e n Strawson, The Secret Connexion: Causation, Realism, and David Hume (Oxford, Clarendon Press, 1 9 8 9 ) . A vigorous defense of the "Old H u m e " against this " N e w H u m e " is Kenneth P. Winkler, " T h e N e w H u m e , " in the Philosophical Review 1 0 0 , 4 (October 1 9 9 1 ) .

beliefs produced thereby are unjustified, it is to say, at a m i n i m u m , that on his view there is something intrinsically w r o n g or deficient about that practice and about those beliefs. B u t in the light of the passages cited, I think w e must conclude that H u m e did not believe that unless, of course, one regards a belief's h a v i n g a degree of "evidence" less than the highest as a deficiency in it. W h a t , then, did H u m e wish to say about this practice and the beliefs it produces? Pretty clearly he had two closely connected main points in mind. H e insisted that the practice of induction is not a manifestation
of R e a s o n
but of that very different
dynamic
of
belief-formation which L o c k e called custom and w h i c h he w a r n e d us so firmly
against. A n d secondly, H u m e contended
that the L o c k i a n
practice gives us access to those facts to which induction gives us access only if w e make use of a premise which is the product not of R e a s o n or a n y other faculty of insight, but of habit or custom. In H u m e ' s rhetoric one senses nostalgia for Locke's vision; he wishes it were true. But in fact H u m e has broken with the L o c k i a n vision in a fundamental w a y .
8
Locke's principle of proportionality said that we ought to proportion the level of confidence w e place in a proposition to its probability on our evidence concerning it, w h e n that evidence attains the level of being satisfactory. T h e evidence
is to consist
of things that
we
intuitively or demonstratively "perceive" to be true; and it is R e a s o n , says L o c k e , w h i c h informs us as to the probability of a proposition on a body of evidence. H u m e posed a simple but profound question to this L o c k i a n vision: How
are w e to tell when the evidence is satisfactory - i.e., when it is a
reliable indicator of the truth or falsehood of the proposition? L e t us grant that it is R e a s o n which tells us w h a t degree of probability a proposition has on a given b o d y of evidence. W h a t tells us whether that evidence is satisfactory? H u m e argued, decisively in my j u d g m e n t , that within the L o c k i a n vision no acceptable answer to this question is 8
thus I hold thai H u m e is a skeptic concerning inductive inference, his particular form of skepticism consisting in his affirmation of the two theses concerning the limits of Reason formulated in the text above. A similar interpretation of H u m e as skeptic is developed in a (thus far) unpublished paper by Kenneth I'. Winkler, "Hume's Skepticism." There has been a great flowering of discussions of Hume's skepticism in recent years. T o cite only a few: Annette Baier, A Progress of Sentiments ( C a m b r i d g e , H a r v a r d University Press, 1 9 9 1 ) ; T . B e a u c h a m p and A .

available. In particular, R e a s o n is not c a p a b l e of telling us when beliefs concerning present and remembered experience satisfactory evidence for some proposition concerning
constitute
(contingent)
facts w h i c h w e h a v e not experienced and are not experiencing. R e a s o n , H u m e assumes, is our faculty for apprehending necessary relations a m o n g propositions
(and a p p a r e n t l y for apprehending
necessary truths in general). L o c k e held essentially the same view. O f course, L o c k e also held that R e a s o n is our faculty for a p p r e h e n d i n g the probability of a proposition on a b o d y of evidence; but he regarded that relationship as a species of necessary relation. H u m e expresses no disagreement. S o suppose I hear a certain noise and infer that a motor vehicle is going by on the street in front of m y house. C a n I arrive at that conclusion, from that experience, by R e a s o n ? Certainly there is no necessary relation between that noise and a motor vehicle's going by, says H u m e . It is not a necessary property of this noise that it is m a d e by a motor vehicle going by, or that it is an accompaniment
of that.
The noise could
h a v e been
made
by
something else; indeed, it is logically/ontologically possible that it was not caused by a n y t h i n g at all. In short, there is here no "relation of ideas" susceptible of being intuited or demonstrated. 'Tis easy to observe, that in tracing this relation, the inference we draw from cause to effect, is not derived merely from a survey of these particular objects, and from such a penetration into their essences as may discover the dependence of the one upon the other. There is no object, which implies the existence of any other if we consider these objects in themselves, and never look beyond the ideas which we form of them. Such an inference would amount to knowledge, and would imply the absolute contradiction and impossibility of conceiving any thing different. ( T 8 6 - 7 ) W h a t , then, accounts for m y inference, if I do not, by R e a s o n , penetrate into the essence of this noise so as to be able to discern that it must h a v e been m a d e (or at least a c c o m p a n i e d ) by a motor vehicle going b y ? W e l l , remember w h a t w e h a v e already seen about the workings of our practice of induction: I t is because I h a v e often experienced a noise of this sort being m a d e by a motor vehicle going by that I now infer, upon hearing this particular noise, that a motor vehicle is going by. Perhaps, then, these present and remembered facts function for me as evidence; and perhaps m y R e a s o n tells me that this evidence logically supports the conclusion that p r o b a b l y a motor vehicle is going by. Perhaps, in turn, it is m y R e a s o n telling m e this that produces in me the belief that a motor vehicle is going b y .

W h a t , on this construal, would the a r g u m e n t look like? S o m e t h i n g like this: 1 . I h a v e noted in the past an invariant correlation between noises of a certain sort and a motor vehicle going by; 2 . T h e noise I a m presently hearing is of that sort; C . H e n c e it is highly probable that a motor vehicle is going by. B u t the a r g u m e n t as it stands is obviously not deductively valid, says H u m e ; the premises do not entail the conclusion. Since the correlations I h a p p e n to h a v e noticed m a y not be representative of reality in general, there is nothing impossible about the premises being true and the conclusion false. R e a s o n , w h i c h , to say it once again, is our faculty for a p p r e h e n d i n g necessary truths, does not enable us to conclude, just from these premises, that the conclusion is true. As to past experience, it can be allowed to give direct and certain information of those precise objects only, and that precise period of time, which fell under its cognizance: but w h y this experience should be extended to future times, and to other objects, which, for aught we know, m a y be only in a p p e a r a n c e similar; this is the main question on which I would insist. T h e bread, which I formerly eat, nourished me; that is, a body of such sensible qualities was, at that time, endued with such secret powers: but does it follow, that other bread must also nourish me at another time, and that like sensible qualities must always be attended with like secret powers? The consequence seems nowise necessary. A t least, it must be acknowledged that there is here a consequence d r a w n by the mind; that there is a certain step taken; a process of thought, and an inference, which wants to be explained . . . When a m a n says, I havefound, in all past instances, such sensible qualities conjoined with such secret powers: A n d when he says, Similar sensible qualities will always be conjoined with similar secret powers, he is not guilty of a tautology, nor are these propositions in any respect the same. Y o u say that the one proposition is an inference from the other. But you must confess that the inference is not intuitive; neither is it demonstrative: O f what nature is it then? (E 3 3 - 7 ) It is not difficult to see w h a t sort of premise must be added to the a r g u m e n t as it stands to make it deductively valid. I f w e a d d a premise to the effect that m y sample was and is representative, and thus, reliable - was representative of frequencies in reality up to this time, and, assuming the uniformity of the past with the present on these matters, remains representative — then w e h a v e a valid a r g u m e n t . H u m e , focusing on the latter of these two points, puts it like this: " I f reason determined us, it would proceed upon that principle, that instances, of which we have had no experience, must resemble those, of which we
John
Locke and the ethics of belief
have had experience, and that the course of nature continues always uniformly the same (T 8 9 ) . T h e entire a r g u m e n t would then look like this: 1 *.
I h a v e noted in the past an invariant correlation between noises of a certain sort and a motor vehicle going by.
2*.

representative.
O u r project, to repeat, is to discover whether I a m or can be "determined by reason to make the transition" (7" 8 8 ) from hearing this noise to the conclusion that it is v e r y p r o b a b l e that a motor vehicle is going by. R e a s o n now tells me that the a r g u m e n t proposed is valid. A n d I know premise ( 1 * ) b y w a y of m e m o r y of past experience,
and premise
( 3 * ) by w a y of awareness of
present
experience (plus comparison with remembered experience). S o the question focuses on the cpistemological status of ( 2 * ) . Certainly this is not a necessary truth, knowable by intuition or demonstration.
H u m e docs not focus on the fact that it is not
necessary that my sample have been representative. H e focuses instead on the fact that there is no necessity about present and future nature being uniform with nature of the past - w h i c h implies, of course, no necessity
about such
nature being
uniform with already
observed
nature. " W e can at least conceive a c h a n g e in the course of nature; which sufficiently
proves, that such a c h a n g e is not
absolutely
impossible" ( T 8 9 ) .
M a y I not clearly and distinctly conceive that a body, falling from the clouds, and which, in all other respects, resembles snow, has yet the taste of salt or feeling of fire? Is (here any more intelligible proposition than to affirm, that all the trees will flourish in December and J a n u a r y , and decay in M a y and June? N o w w h a t e v e r is intelligible, and can be distinctly conceived, implies no contradiction, and can never be proved false by any demonstrative argument or abstract reasoning a priori. (E 3 5 )
B u t obviously premise ( 2 * ) is also not a simple report of present or remembered experience. Perhaps, then, it is itself a contingent truth inferred from remembered or past experience. B u t if so, then the v e r y questions w e h a v e posed concerning ( 1 ) now arise concerning ( 2 * ) .

H u m e ' s conclusion is that our actual practice of induction is not an exercise of R e a s o n , nor can the beliefs w h i c h the practice produces in us be arrived at by arguments w h i c h R e a s o n tells us are valid and whose premises are the deliverances of Reason, memory, and awareness. A l w a y s w e shall h a v e to a d d a premise which is the product not of R e a s o n , m e m o r y , or awareness but of sheer habit, mere custom. " R e a s o n can never show us the connexion of one object with another, though aided by experience, and the observation of their constant conjunction in all past instances" (7" 9 2 ) . " W h e n w e pass from the impression of one [object] to the idea or belief of another, w e are not determined by reason, but by custom or a principle of association"
(T97)-

M a n y readers of H u m e find something deeply counter-intuitive in his a r g u m e n t . A s w e a c c u m u l a t e more and more experience of nature and nature continues to prove uniform in its observed workings, does not Reason tell us that w e a r c more and more entitled to believe that nature throughout is uniform with respect to such workings, present 11
Cf. 3 7 f>: " F o r all inferences from experience suppose, as their foundation, that the future will resemble the past, and that similar powers will be conjoined with similar sensible qualities. If there be any suspicion that the course of nature may change, and that the past may be no rule for the future, all experience becomes useless, and can give rise to no inlcrcncc or conclusion. It is impossible, therefore, that any arguments from experience can prove this resemblance of the past to the future; since all these arguments arc founded on the supposition of that resemblance." By saying that the belief arises "without any new reasoning or conclusion," H u m e means that it "arises immediately." " O f this I can be certain," he says, "because I never am conscious of any such operation, and find nothing in the subject, on which it can be founded" (r 1 0 2 ) . T h e claim that custom is a mode of bclicf-fbrmatioti which operates immediately is then used by H u m e as an argument for his claim that as a matter of fact, the practice of induction is not an exercise of Reason: " T h e custom operates before we have time for reflexion. The objects seem so inseparable, that we interpose not a moment's delay in passing from the one to the other. But as this transition proceeds from experience, and not from any primate connexion betwixt the ideas, we must necessarily acknowledge, that experience may produce a belief and a judgment of causes and effects by a secret operation, and without being once thought of. This removes all pretext, if there yet remains any, for asserting that the mind is convinced by reasoning of that principle, that instances of which we have no experience, must necessarily resemble those, of which we have. For we here find, that the understanding or imagination can draw inferences from past experience, without reflecting on it; much more without forming any principle concerning it, or reasoning upon that principle" ( T 1 0 4 ) . He does not wish to deny, however, says H u m e , that "in other associations of objects, which arc more rare and unusual, [the mind] may assist the custom and transition of ideas by this reflexion. N a y we find in some cases, that the reflexion produces the belief without the custom; or more properly speaking, that the reflexion produces the custom in an oblique and artificial manner."

and future nature uniform with past, and distant nature uniform with local? W h a t might H u m e say, in addition to w h a t he has already said, to get us to share his intuition on this matter? Perhaps something like this: W e can, of course, discover that a larger later sample correlations, call it Beta,
of
exhibits the same invariance (or relative
frequency) that our earlier smaller sample, call it Alpha,
exhibited.
A c c o r d i n g l y , if I later m a k e an inference to non-sampled events, I do not h a v e to be content with a d d i n g the premise that
relative
frequencies in sample Alpha are representative of relative frequencies in reality. I can instead add the premise that frequencies in sample Beta - a later and larger sample - are representative of frequencies in reality. B u t how do I know that that is true?

prove that frequencies in Beta are representative of frequencies in reality in general? O f course, I can collect a yet larger sample, I m a y discover that frequencies

were representative
of

B y the very nature of the case, when I infer to the existence of some event beyond m y sample, but on the basis of m y sample, I must suppose that relative frequencies in the sample were and are representative of relative frequencies in reality without h a v i n g confirmed that they a r c . W e can confirm that one sample is representative of another sample. W h a t w e cannot do is confirm that our sample is representative of reality
without h a v i n g
sampled all the reality on the matter, in which case w e no longer make an inductive inference beyond our sample but just report remembered and present experience. Unless, of course, it was the case, and w e somehow knew it was the case, that there are insufficient unsampled cases to render our sample unrepresentative under even the worst scenario. But perhaps this w a y of looking at the matter is still too quick to be persuasive. S o let us arrive at H u m e ' s point b y looking a bit more deeply into probability and Locke's use thereof. A n d since H u m e casts the argument in terms of relative frequencies and the determination of objective statistical probabilities, let us do so as well. Begin by distinguishing concerning

presidential election had been a matter of such concernment to me that I w a s required to try to do m y best to get at the fact of the matter, w h i c h in this case is the (statistical) probability of the matter. A n d suppose that the only relevant thing I knew about Paul w a s that he w a s a registered M i c h i g a n voter. O n Locke's view, the first step in doing m y best in this case consists of forming a sample
which
constitutes satisfactory evidence as to Paul's preference. S o suppose I take a sample of registered M i c h i g a n voters, a sample w h i c h is reliable in its amplitude and representativeness
as to candidate-
preference in this population; and suppose that, in this sample, 5 5 percent prefer Clinton and 4 5 percent prefer Bush. Consider then the following propositions: 1 . T h e relative frequency, in this sample of registered M i c h i g a n voters, of those w h o prefer Clinton is - 5 5 . 2 . T h e probability on the evidence specified in ( 1 ) , that in r a n d o m l y selecting a m e m b e r of the sample one will select one w h o prefers Clinton, is - 5 5 . 3 . T h e probability on the evidence specified in ( 1 ) , that in r a n d o m l y selecting a member of the wider population of registered M i c h i g a n voters one will select one w h o prefers Clinton, is 5 5 . 4. E a c h m e m b e r of the sample is such that the probability on the evidence specified in ( 1 ) , that that m e m b e r prefers Clinton, is - 5 5 . 5 . E a c h m e m b e r of the wider population of registered M i c h i g a n voters is such that the probability on the evidence specified in ( 1 ) , that that m e m b e r prefers Clinton, is - 5 5 . 6. T h e objective statistical probability that, in r a n d o m l y selecting a member of the sample, one will select one w h o prefers Clinton, is - 5 5 . 7. T h e relative frequency in the wider population of those w h o prefer Clinton is - 5 5 . 8. T h e objective statistical probability, that in r a n d o m l y selecting a m e m b e r of the wider population one will select one w h o prefers Clinton, is - 5 5 . 9. E a c h m e m b e r of the wider population is such that the objective statistical probability that that m e m b e r prefers Clinton is 5 5 . 1 0 . T h e objective statistical probability that Paul prefers Clinton is • 5 5 (Paul being a m e m b e r of that wider population of registered M i c h i g a n voters). 11.
Paul prefers Clinton.
W e can agree that ( 1 ) entails (2) through ( 5 ) . I n d e e d , even if this

sample were not sufficient in amplitude and representativeness, as I h a v e specified that it is, ( i ) would still entail (2) through ( 5 ) . I f a sample of registered M i c h i g a n voters yielded the relative frequency specified in ( 1 ) , then the c h a n c e on that evidence of selecting someone w h o prefers Clinton, in r a n d o m l y picking someone either from the sample or from the wider population, would be - 5 5 . But the evidence might be very skimpy or skewed; and if one knew or believed it w a s , one would be well advised not to do m u c h with ( 3 ) and ( 5 ) . Starting with (6) w e m o v e beyond claims as to w h a t is probable on this evidence to claims concerning objective statistical probability. In (6), however, w e h a v e not yet moved outside the circle of evidence, with the consequence that (6) is also entailed by ( 1 ) . Indeed, even if the sample were not reliable in its amplitude and representativeness, (6) would still be true for a sample which displayed the relative frequencies cited in ( 1 ) . But when with (7) w c do m o v e outside the circle of evidence, things are different. I f the sample is representative
that is to say, if the
relative frequencies in the sample m a t c h those in the population then, but only then, will (7) and (8) also be true. C o r r e s p o n d i n g l y m o v e from logic to epistemology
to
only if one is entitled to believe that
one's sample is representative is one entitled to believe (7) or (8) on the basis of one's sample. I h a v e argued that L o c k e saw this point; hence his insistence that, before a n y t h i n g else, one make sure that one's evidence is satisfactory. W h e n we come to (9) and ( 1 0 ) , yet a different consideration enters the picture. Propositions (9) and ( 1 0 ) are also statements of objective statistical probability. But whereas (8) speaks of the c h a n c e of picking out a Clinton-preferrer in r a n d o m l y selecting someone from the population of registered M i c h i g a n voters, (9) and ( 1 0 ) speak of the probability, for a given person, 0/ that person
preferring Clinton.
Proposition ( 1 0 ) actually picks out such a person, namely Paul, the person of concern in all this. Proposition (9) does not do that; instead it generalizes. It says that for a n y person you pick out from a m o n g registered M i c h i g a n voters, be it Paul or w h o e v e r , the probability that that person prefers Clinton is - 5 5 . But suppose that Paul
or anyone else from a m o n g the registered
M i c h i g a n voters - is a worker for the Bush c a m p a i g n in L a n s i n g . T h e proportion of Clinton-preferrers among workers for the Bush c a m p a i g n in L a n s i n g w a s surely very low - say, 1 0 percent. O n the other h a n d , Paul m a y h a v e been one of those workers for the Bush c a m p a i g n w h o

b e c a m e disillusioned with Bush - w e are to suppose that the poll w e are imagining took place just before the election.
T h e relative
frequency of Clinton-preferrers a m o n g registered M i c h i g a n voters w h o were workers for the Bush c a m p a i g n in L a n s i n g but b e c a m e disillusioned would no d o u b t h a v e been higher than 1 0 percent but still lower than 5 5 percent. T h e likelihood of Paul's preferring Clinton can be determined only by reference to the relative frequency of Clinton-preferrers in the intersection of all groupings to which Paul belongs w h i c h are relevant to his presidential preference. O n l y if one's sample is satisfactory in relevance (with respect to Paul) as well as satisfactory in representativeness will it be the case that ( 1 0 ) is true if ( 1 ) is. A n d correspondingly, one would be entitled to believe ( 1 0 ) only if one knew or was entitled to believe that one's sample was thus satisfactory, plus knowing or believing with entitlement that the evidence was sufficiently ample. T h e sample which I h a v e invited us to imagine is not good evidence for (9) and ( 1 0 ) . T o be entitled to believe either (9) or ( 1 0 ) , one needs to know m u c h more. I have

point.
The point
has
destructive consequences for his position which he either overlooked or ignored, as I shall shortly point out. B u t his insistence that w e must look for evidence both pro and con should, I think, be seen as an a d u m b r a t i o n of the point." A t other points, L o c k e w a s less perceptive. First, he not only insisted that one's level of confidence in a proposition be proportioned to its probability on satisfactory evidence; he insisted, so far as I can tell, that if the probability on such evidence is a b o v e - 5 , then one should believe the proposition - or perhaps he just assumed that if one's level of confidence is a b o v e - 5 , then one will
believe. E i t h e r
w a y , surely this is not correct. I f the proposition that Paul prefers Clinton is just slightly more probable than not on some evidence, one would not automatically believe that proposition, nor do I see any reason to think that one should try to bring it about that one would believe it. T h e r e might be circumstances in w h i c h the best thing to do w o u l d be to bet on it; but that doesn't require believing it. One's level of confidence will and should be higher than that before one believes. Secondly, L o c k e was mistaken as to the w a y in which inductive " A useful discussion of many of the points rehearsed above is to be found on pp. 9 4 - l o g of L .

Locke and the ethics of belief
evidence entitles one to some level of confidence in a proposition. A s L o c k e saw it, once one has collected evidence w h i c h is of a quality sufficient to bring it over the threshold level of reliability, one is then finished
with considerations of quality. O n e then concerns oneself
exclusively with the determination of relative frequencies in this satisfactory evidence. But surely this is not correct. Consider proposition ( 7 ) , that the relative frequency in the wider population of those w h o prefer Clinton is - 5 5 . O n the evidence, this has a probability of i-o; nothing could be more probable on that evidence. L o c k e instructs us then to believe this proposition with m a x i m a l firmness. But surely that would be a very stupid thing to do, because the evidence is not good enough for that. A n o t h e r e x a m p l e to make the same point: Suppose that in some run of A s which one samples, it turns out that all of them are Bs; the relative frequency of Bs a m o n g A s is 1 o. In m a n y cases it would be sheer folly to believe with m a x i m a l confidence that the probability that the next A will be a B is i-o. Y e t that is w h a t Locke's rule instructs one to do. O n l y if it was somehow a p p r o p r i a t e to h a v e m a x i m a l confidence that the sample is representative would that level of confidence in that proposition be a p p r o p r i a t e . O r imagine two samples of registered M i c h i g a n voters, S and S * , both of which are a b o v e the threshold level of reliability, but with S * much more a m p l e than S . I f it is correct to think of us as h a v i n g obligations to proportion levels of confidence, surely this difference is relevant to determining the entitled levels. Suppose, to be specific, that both S and S * show that 5 5 percent prefer Clinton, but that S is of 2 0 0 voters whereas S * is of 2 0 , 0 0 0 . Surely the latter entitles me to believe both (7) and (8) with more confidence than the former entitles me, that is, to believe with more confidence both that the relative frequency in the wider population
of those w h o prefer
Clinton is 5 5 percent, and that the probability is - 5 5 that in r a n d o m l y selecting a m e m b e r of the wider population, I shall select someone w h o prefers Clinton. S o too, if my concern is Paul's preference and I h a v e two samples,
both of w h i c h meet

I n short, w e are not finished with considerations of quality of evidence once w e h a v e determined
that the quality is over the
threshold of reliability. T h e rule that our level of confidence in a
Hume's
attack
177
proposition is to be proportioned to its probability on satisfactory evidence gives radically mistaken advice. S o quality of evidence remains relevant. B u t reflection on phenomenon
the
of quality of evidence makes it clear that inductive
inference is far from fitting into Locke's vision in the w a y he thought it did. Locke's aim w a s to g r o u n d our beliefs on insight. A proposition might h a v e a high probability on fully reliable evidence and yet be false; thus the practice is not a g u a r a n t e e of truth. Ideally, though, the possibility of error will be confined to that point. I n our exposition of L o c k e w e found him conceding that it cannot be confined to that point; our attempts to identify episodes of direct awareness are also fallible. B u t now it is clear that insight is lacking at crucial junctures in the process as well. It's not just that our attempts to identify episodes of insight are fallible; at crucial junctures w e couldn't possibly h a v e insight. I f one arrives at the point w h e r e one "sees" w h a t are the relative frequencies in one's sample, then one is also in a position to "see" that (2) through (6) are true. But when one steps outside the circle of evidence, one goes beyond insight
u n a v o i d a b l y so. If one's sample is
representative, then (7) and (8) will be true if ( 1 ) is. F u r t h e r m o r e , if one knows (or believes with entitlement) that ( 1 ) is true, and also knows (or enlilledly
believes)
that the sample is representative,
then one is also in a
position to know (or believe with entitlement) (7) and ( 8 ) . But if one doesn't
know (or believe with entitlement)
that one's sample is
representative, one has no ground whatsoever for believing (7) or ( 8 ) . A n d now to c o m e back to H u m e : H u m e ' s central point was that one can never "see" that one's sample is representative. E v e n if polling studies show that samples of this sort h a v e a l w a y s , in the cases studied, been representative, that falls short of enabling one to "see" that this sample is representative. T h e point about relevance is also relevant here. Sometimes
some
scientific
(or homespun)
theory
assures one that in cases of the sort one is dealing with, no other factors are relevant than the ones of w h i c h one has already taken account. But often no such theory is available; and even when it is, w e once again run into the problem of our inability to "see" that nature is uniform. T h e theory itself will simply h a v e assumed that it is. T h a t all the factors w h i c h are relevant in this case have been taken into account is something one can never just "see." B u t only if they h a v e all been taken into account will it be the case that if ( 1 ) is true, (9) and ( 1 0 ) will be so also. A n d in the absence of knowing (or believing with
1 8 7
John
Locke and the ethics of
belief
entitlement) that they h a v e been, one is not entitled to m o v e , from one's knowledge (or entitled belief) of ( i ) , to (9) and ( 1 0 ) . W e c a n put the point like this: Induction cannot be grounded in direct awareness. I f w e confined ourselves to direct awareness, w e would never make inductive inferences. B u t , as L o c k e himself saw, w e h u m a n beings cannot live without m a k i n g such inferences. O u r situation consigns us to going out beyond w h a t direct awareness tells us has a probability of so-and-so on some b o d y of evidence. I f R e a s o n be understood as a faculty of direct awareness, our situation consigns us to going out beyond the reach of Reason. It w a s T h o m a s Reid's contribution to e x p a n d and systematize Hume's a r g u m e n t . N o philosopher in Reid's d a y succeeded
in showing
that
the existence
nor in ours - has
of material objects is
probable on evidence consisting exclusively of items of direct awareness which w e can see to be satisfactory as evidence. T h e use of Locke's practice, if w e require that we see that the evidence is satisfactory, will thus leave us with no beliefs about such objects. Y e t w e h u m a n beings have a very good mode of access to a great m a n y such facts: w e call it perception. S o too, one's m e m o r y puts one in touch with a large body of facts which Locke's method, when insight into the satisfactoriness of the evidence is required, is i n c a p a b l e of reaching. It has even been argued in recent years
cogently, in my judgment - that w e might
well have faculties and practices which give us better access to certain 12
facts about (iod than does the Lockian p r a c t i c e . T h e basic point is the same in all these cases: W e h u m a n beings are endowed with a variety of processes for immediate belief-formation
which give us more
reliable access to facts of various sorts than does the L o c k i a n evidentialist practice with its base consisting exclusively of beliefs evoked by episodes of direct awareness. A n d as to mediate
beliefs,
recent discussions in philosophy of science suggest that there are bodies of facts to which modes of mediate belief-formation other than that which L o c k e proposes are our best modes of access. I think one can see w h y L o c k e thought it self-evidently true that the best w a y to get in touch with those facts of w h i c h one cannot h a v e direct awareness is to start with facts of w h i c h one does h a v e direct awareness and then either construct deductive proofs or, where that proves impossible, follow the principles of evidence, appraisal, and 1 2

proportionality. W h a t could be a better w a y , more reliable and powerful, than this? Y e t L o c k e w a s mistaken, and surprisingly so: F o r v e r y m a n y facts, w e h a v e better modes of access than this - better both in the sense of less often putting us out of touch with reality and in the sense of more often putting us in touch with reality. But can w e be certain of this, someone is sure to ask. I f it is certainty w e insist on, w e are lost indeed. F o r w e can be mistaken even in our attempt to pick out acts of direct awareness - even in our attempt to pick out cases of certainty!

Locke's originality
I
HOW DESCARTES'S
PROJECT
DIFFERED
J o h n L o c k e , after distinguishing sharply between knowledge, on the one h a n d , and belief (opinion, assent) on the other, proceeded to offer a general ethic for the g o v e r n a n c e of our belief. "Reason must be our last j u d g e and guide in everything," he said ( i v , x i x , i 4 ) . O r more illuminatingly: Assent, "if it be regulated, as is our duty, cannot be afforded to anything, but upon good reason . . . F o r he governs his assent right, and places it as he should, w h o in any case or matter whatsoever, believes or disbelieves, according as reason directs him" ( i v , x v i i , 2 4 ) . W e have seen that it is to all and only matters of m a x i m a l "concernment" that these ringing affirmations were meant to apply. T h a t there is a general ethic of belief, and that in this ethic Reason has a central role
once these convictions had been clearly formulated
and persuasively propounded by L o c k e , they b e c a m e prominent in the mentality of modernity. In that mentality, Locke's view as to the content of that ethic, and the proper role of R e a s o n therein, b e c a m e classic: F o r a n y proposition of m a x i m a l "concernment" w h i c h is not intuitively
or demonstratively
known
to
be true, Reason
is
to
determine the probability of the proposition on satisfactory evidence, and
we
are to place a level
of confidence
in
the
proposition
proportioned to w h a t R e a s o n tells us is that probability. M y thesis that L o c k e w a s the first great philosopher to propound this vision will strike m a n y readers as perversely implausible. Is it not just a v a r i a n t on Descartes's vision? W a s not Descartes's M e t h o d the direct ancestor of Locke's proposed practice? W a s not Descartes's Rulesfor
the Direction of the Mind the direct ancestor of Locke's Conduct of
the Understanding?
I propose now to consider this issue of priority; and
then, in the light of our analysis of Descartes's contribution, pinpoint more precisely than I h a v e thus far the character of Locke's originality. 180
How Descartes's
Project
Differed
181
T o prevent misunderstandings let me say emphatically here at the beginning, before w e set out, that of course there are important similarities between Descartes's M e t h o d and Locke's proposed practice. But neither Descartes's M e t h o d nor Locke's practice was a free-standing entity; the M e t h o d was part of a project, the practice, part of a proposal. A n d m y contention will be that when w e take Descartes's project
of "contemplation
of the truth," along with the rules he
proposed for that, and c o m p a r e those, in the one direction, with the medieval project of scientia,
and in the other direction, with Locke's
proposal for a reformation in our w a y of conducting our understandings, it then becomes clear that Descartes's project is m u c h more the continuation of the medieval project of scientia than the anticipation of Locke's proposal for governing the understanding. It should at once be added, however, that when w e consider the
propaedeutic
Descartes recommends for those w h o wish to engage in that traditional project of scientia,
and the results at which he himself arrived w h e n
pursuing the project, w e catch sight of distinctly modern features. A s to the results, L o c k e was speaking not only for himself but for others as well when he remarked, about Descartes, that " I must a l w a y s acknowledge to that justly-admired gentleman the great obligation of m y first deliverance from the unintelligible w a y of talking of the philosophy in use in the schools in his time" (First Letter to the Bishop of Worcester; Works 1 1 1 , 4 8 ) . Descartes is a bridge between an old world d y i n g and a new world aborning. T h e central point is this: Descartes never offered any general proposals for the g o v e r n a n c e of belief (opinion). Descartes w a s , of course, fully as a w a r e as L o c k e of the cultural crisis at the founding of modernity - namely the anxiety of h a v i n g to govern our belief in general, and settle our moral and religious quandaries in particular, when our once-unified tradition has fragmented into partisan quarrels. But the solution he proposed to that crisis - in so far as he did propose a solution - was that scienlia
be practiced on better grounds, with
better preparation, and more expansively, than was currently being done. E d m u n d Husserl, w h o also supposed that a cultural crisis of roughly that sort could be met by the more resolute pursuit of
scientia,
is our preeminent c o n t e m p o r a r y Cartesian. Descartes did indeed h a v e a "provisional moral code" for guiding his life so that he could w o r k productively in the "contemplation of the truth." B u t he never proposed this code for e v e r y b o d y ; and he never suggested that the code w a s based on "the deliverances of R e a s o n . " His true hope w a s
Locke's

B u t the M e t h o d was not for the g o v e r n a n c e of opinion but for the construction of scientia. Descartes took over intact the traditional medieval tripartite scheme of knowledge, faith, and opinion, offering no substantial innovation in how these are to be understood. His attention fell almost entirely on that species of knowledge which is scientia.
His project was to work at that.
Locke, by contrast, discarded the tripartite scheme by treating faith as a species of belief (opinion). T h e n , convinced that scientia could never come to much, he paid it little attention. H e offered no method for its construction. Instead he recommended the systematic pursuit by men of leisure of the new project which he called "natural philosophy." But natural philosophy, in his view, yields belief, not knowledge. It is not a form of scientia. Descartes entitled his Discourse, "Discourse on the method of rightly conducting
his reason
(saenliae)."

1 1 , 1 2 ) . A n d in his late unpublished dialogue, The
Search for the Truth,
Descartes has his spokesman in the dialogue,
E u d o x u s , say at one point: " I confess that it would be dangerous for someone w h o does not know a ford to venture across it without a guide, and m a n y h a v e lost their lives in doing so. B u t you h a v e nothing
to fear if y o u follow
me. Indeed, just such fears h a v e
prevented most men of letters from acquiring a b o d y of knowledge w h i c h w a s firm and certain enough to deserve the n a m e 'science' (scientia)"
( C S M 1 1 , 4 0 8 ) . I suggest that Descartes, throughout his
career, had his eye on the construction of scientia. His M e t h o d w a s a method for the construction of that and that alone. W i t h a qualification to be mentioned later, Descartes took scientia to be w h a t the high medievals (and Aristotle) took it to be - and w h a t L o c k e still took it to be. T h e fundamental criterion is certitude: W h a t is truly scientia will h a v e certitude. " N o act of awareness (cognilio) that can be rendered doubtful seems fit to be called knowledge
(scientia)"
says Descartes in his reply to the second set of objections to the Meditations
(CSM
1 1 , 1 0 3 ) . In his discussion of R u l e T w o in Rules for
the
Direction of the Mind he says that "all knowledge (scientia) is certain and evident cognition" ( C S M 1 , 1 0 ) . A n d in his discussion of R u l e Threehe speaks of w h a t is desired as "so evident and certain as to be beyond dispute," "a knowledge of things with no means of being mistaken" (CSM
1 , 1 4 ) . T h r o u g h o u t his career, Descartes felt tension between
the ideal of scientia, on the one hand, and the actual science which he developed, on the other; sometimes he argued that the actual science really did fit the ideal, and sometimes he conceded that it did not and proposed an adaptation of the ideal. B u t he never surrendered the ideal; Descartes, on this issue, was a c o n s e r v a t i v e .

Descartes appears, throughout his career, to have thought of the (metaphysically)
certain as h a v i n g two marks. It is incorrigible: "no

A n d it is indubitable.
A
mode
of
apprehending a proposition is indubitable just in case a person, when apprehending the proposition in that mode, could never h a v e a good enough reason for doubting it - that is, could never believe another proposition in such a w a y that one then had a good reason for 2

(Shortly I shall
call this rational indubitability, to distinguish it from psychological indubitability.) Scientia is to be built up from apprehensions w h i c h are incorrigible and indubitable.

I see no evidence that he ever
changed his mind on this; the only c h a n g e is that in his later writings he speaks of "the natural light" rather than of intuition.
Both
intuition and deduction are thought of as apprehension, apprehension of propositions. T h e w o r d intueri itself suggests apprehension. W h a t is it that characterizes those modes of apprehension
of
propositions in which intuition and deduction are at work -- thus, those modes fit to lay at the foundation of scientia? Indubitability and incorrigibility, of course. B u t is there anything phenomenological or quasi-phcnomenological

The point on which my account of Descartes's (onccpl of metaphysical certainty differs most decisively from Curlcy's is that Curlcy's is entirely "internal," including 110 such objective phenomenon as incorrigibility. Il seems to me that the evidence is in favor of Descartes's having wanted to include that; and my conclusion, that that is pari of ihe concept, will be crucial lo my subsequent argument. For the rest, the main issue between me and (lurley in the accounts w c oiler is w h c t h e r ^ W enough reason for is ultimately reducible to psychologically compelling reason for. Is the appearance of normativity in the phrase "good reason" no more than an appearance? Curley's own view is that the supposition that it is no more than that is "a kind of naturalistic fallacy"; yet he concludes that that is how Descartes was thinking. I'm quite sure (hat Descartes did believe thai what constitutes^W reasons for us does depend, at bottom, on what the belief-forming faculties that G o d gave us compel us to believe. But my guess is that he would want to add to this something about properly functioning capacities, or about the capacities of a properly formed adult. T h a t would be where the normativity comes in. Accordingly, I shall stick with the phrase "good reason" and not follow C u r l c y in using only the notion of assent-compulsion in explicating Descartes's concept of metaphysical certainty. H a r r y Frankfurt's book, Demons, Dreamers, and Madmen, remains in my judgment much the best book on Descartes. From amidst the vast literature on Descartes, I shall pay it the particular honor of expressing agreement and disagreement. O n pp. 1 y^lf. of his book, Frankfurt suggests that Descartes in speaking of clear and distinct perception was not trying to pick out a certain phenomenology; rather, the concept of clear and distinct perception, says Frankfurt, just is the concept of entertaining a proposition in a w a y such that it is indubitable for one. T h o u g h this suggestion has some attractive features, it seems to me that certain texts are decisively against it. F'or example, when Descartes explains what he has in mind by clear and distinct perception in Principles 1 : 4 3 - 6 , he uses very phenomenological language. Here is

attentive mind, w h i c h is so easy and distinct that there can be no room for doubt about w h a t w e are understanding. Alternatively, and this comes to the same thing, intuition is the indubitable conception of a clear and attentive mind which proceeds solely from the light of reason" ( C S M 1 , 1 4 ) . A s examples of propositions
w h i c h can be
intuited, Descartes says that "everyone can mentally intuit that he exists, that he is thinking, that a triangle is bounded by just three lines, and a sphere by a single surface, and the like." A n d for those w h o grant that there are such perceptions but doubt that a scientia built u p from them will come to very m u c h , Descartes adds: "Perceptions such as these are more numerous than most people realize, disdaining as they do to turn their minds to such simple matters" ( C S M 1 , 1 4 ) . Descartes's explanation of deduction in the Rules is parasitic on that of intuition: The self-evidence and certainty of intuition is required not only for apprehending single propositions, but also for any train of reasoning whatever. T a k e for example the inference that 2 plus 2 equals 3 plus 1; not only must we intuitively perceive that 2 plus 2 make 4, and that 3 plus 1 make 4, but also that the original proposition follows necessarily from the other two. T h e r e m a y be some doubt here about our reason for suggesting another mode of knowing in addition to intuition, viz., deduction, by which we mean the inference of something as following necessarily from some other propositions which are known with certainty. But this distinction had to be made, since very m a n y facts which are not self-evident are known with certainty, provided they are inferred from true and known principles through a continuous and uninterrupted movement of thought in which each individual proposition is clearly intuited . . . Hence we are distinguishing mental intuition from certain deduction on the grounds that we are a w a r e of a movement or a sort of sequence in the latter but not in the former, and also because immediate self-evidence is not required for deduction, as it is for intuition; deduction in a sense gets its certainty from memory. It follows that those propositions which are immediately inferred from first principles can be said to be known in one respect through intuition, and in another through deduction. But the first principles themselves are known only through intuition, and the remote conclusions only through deduction. ( C S M 1 , 1 4 - 1 5 ) W h a t Descartes called the M e t h o d , from the time of the
Discourse
o n w a r d s , consists then of rules for constructing scientia, that is to say, one example: " I call a perception 'clear' when it is present and accessible to the attentive mind" ( C S M i, 2 0 7 ) . Further, it seems to me that regarding the concepts as identical renders unintelligible the "so . . . that" of Rule O n e in the Discourse: "to include nothing more in m y judgment than w h a t presented itself to my mind so clearly and so distinctly that I had no occasion to doubt it" ( C S M 1 , 1 2 0 ) .
Locke's
originality
rules for arriving at a b o d y of propositions each of which has been intuited, or deduced from w h a t has been intuited. A typical medieval would p r o b a b l y h a v e found the second rule, the rule of analysis, a bit strange; but then, it's a good question h o w m u c h attention Descartes himself paid to R u l e s T w o through F o u r .
5
R u l e O n e , on the other
h a n d , follows from the very concept of scientia:
"never to accept
a n y t h i n g as true if I did not h a v e evident knowledge of its truth: that is, carefully to avoid precipitate conclusions and preconceptions, and to include nothing more in m y judgements than w h a t presented itself to m y mind so clearly and so distinctly that I had no occasion to doubt it" ( C S M i , i 2 o ) . The
6
faculty of intuition is at work in the clear and distinct
apprehension of propositions - so w e h a v e found Descartes insisting. But
are there not degrees of this, someone might ask - degrees of
clarity and distinctness of apprehension? Perhaps so, says Descartes. But
then w e can add this: A law pertaining to the working of the
h u m a n mind is that when our attention to a proposition attains a certain high degree of clarity and distinctness, then it is simply impossible to refrain from believing it. O v e r and over Descartes affirms this law: " m y nature is such that so long as I perceive something very clearly and distinctly I cannot but believe it to be true" ( C S M 1 1 , 4 8 ) . " A l l of us h a v e been so moulded b y nature that whenever we perceive something clearly, w e spontaneously give our assent to il and are quite unable to doubt its truth" ( C S M 1 , 2 0 7 ) . ' '' See Garlx'r, Descartes' Metaphysical Physic*, chap. a. '' T h e higli mcdicvals would have said dial scientia proper consists only of propositions deduced from propositions intuited, and does not include those intuited. T h o u g h in one place Descartes acknowledges this usage (Second Set of Replies; C S M 11,100), he himself does not, with any consistency, follow il. S o I have chosen to speak as if Descartes would also include, wilhin scientia, propositions inluiled. In his views (or assumptions) as to the sorts of propositions which are evident to one, Descartes differed from a high medieval like Aquinas. T h e y agreed that necessarily true propositions which arc self-cvidcnl/jcr .v* may be evident to a person; but Aquinas' category of "propositions evident to the senses" would be vigorously disputed by Descartes. O n the other hand, Descartes included among what is evident 10 a person various propositions concerning that person's stales of consciousness; to ihe best of my knowledge, A q u i n a s never takes note of these - though if he had, he surely would have agreed with Descartes that they too are evident to the person. 7
O n e of the most interesting affirmations of the L a w of Assent occurs in Descartes's reply to the Second .Set of Objections to the Meditations ( C S M 1 1 , 1 0 4 ) : "some of these perceptions are so transparently clear and at the same time so simple that we cannot ever think of them without believing them to be true. T h e fact that I exist so long as I am thinking, or that what is done cannot be undone, are examples of truths in respect of which we manifestly possess this kind of certainty. For we cannot doubt them unless we think of them; but we cannot think of them without at the same time believing they are true, as was supposed. Hence w e cannot doubt them without at the same time believing they are true; that is, w e can never doubt them."

W h e n this l a w - let us call it the Law of Assent - when this l a w of the mind comes into operation, then our faculty of intuition is at work. T h e r e is, though, something profoundly implausible about the L a w of Assent w h i c h , so far as I know, Descartes never notices - and w h i c h almost all his commentators overlook
as well. T a k e

proposition which is self-evident to me. Descartes would describe the phenomenon
of a proposition's
being self-evident
to me as m y
apprehending it so clearly and distinctly that I cannot refrain from believing it. N o w let me consider the negation of that proposition. W h a t reason could there possibly be for supposing that I don't also apprehend this proposition
with full clarity and distinctness?
I
apprehend it so clearly and distinctly that I find myself compelled to 8
disbelieve it. T h u s the law in the region, if there is one, is not the law that w h e n e v e r w e apprehend something with a certain high degree of clarity and distinctness, w e are compelled to believe it, but rather that whenever w e thus apprehend it, we are compelled
to believe or
compelled to disbelieve it. In all that follows, so far as I can tell, Descartes could have m a d e the points he wants to make just as well if he had e m b r a c e d this alternative law of assent. ( T h a t is not true for all of his thought.)
H e r e , however, I shall not undertake to i m p r o v e on
Descartes; I shall expound his a r g u m e n t as he himself does, in terms of the L a w of A s s e n t .

R e p e a t e d l y Descartes makes clear that in scientia there is no room for appeal to tradition or authority. In this, too, he is at one with the medievals; as he is in w h a t he sees as the point, the benefit, of the pursuit of scientia: " h u m a n beings, whose most important part is the mind, should devote their main efforts to the search for wisdom, w h i c h is the true food of the m i n d " (Preface to the F r e n c h edition of The CSM
Principles:
1 , 1 8 0 ) . Descartes's innovations begin when he reflects on the
" T h e r e conies to light here a deep difference between Locke and Descartes. Locke thinks in terms of "seeing" a proposition to be true; that consists, on bis view, of "perceiving" that fact which makes the proposition true. Descartes does not think in terms of seeing a proposition to be true. Instead he thinks in terms just of'seeing" or "intuiting" propositions; and his claim is that, if one "intuits" a proposition with a certain high degree of clarity and distinctness, then one is compelled to believe it. From the very beginning, then, the question looms: C a n I be assured that if I am compelled to believe some proposition, it is true? T h e notion of having direct awareness of certain of the facts of reality is simply not part of Descartes's thought. T h u s I disagree with A a r o n , John Locke (Oxford, Clarendon Press, 1 9 7 1 ) , who says that "Locke's intuitionism on the subjective side is identical with that of Descartes" (p. 'z'Zi). 9
T h e response I have often been offered to the point I make in the paragraph above, and typically offered by those commentators w h o notice the difficulty, is that Descartes is working with the notion of clearly and distinctly apprehending that proposition P is true, rather than clearly and distinctly apprehending proposition P. But if that were the case, the demon would be helpless in the face of our clear and distinct apprehensions.

scholastic
conviction that the best preparation is to sift through the textual tradition dialectically. W e must not, indeed, exaggerate the degree of consensus on this; already from the time of the via moderna, a good m a n y scholastics denied that this is the best w a y to prepare oneself for engaging in, say, physics. Nonetheless, nobody proposed, for scientia in general, that the reading of texts be abolished as a p r e p a r a t o r y discipline.
H o w e v e r , Descartes's reflections
had led
him to
the
conviction that w e do not a p p r o a c h the enterprise of distinguishing the certain from the uncertain - an enterprise which lies at the very foundation of the practice of scientia - with open minds. Quite to the contrary, we approach it with prejudgments, acquired from experience and social interchange, as to w h a t we arc certain of. These prejudgments are in good
measure mistaken; and they inhibit our ability
to
distinguish reliably the certain from the uncertain. S o how do we free ourselves from these mistaken praejudicia,
so as to be able to construct a
scientia of pure intuition and deduction
a body of certitude? It was
Descartes's answer to this question that m a d e the practice of scientia in his hands, in spite of all its continuities in concept and method with the mcdicvals, nonetheless something new. A l r e a d y in the early Rules Descartes says that " W e ought to read the writings of the ancients, for it is of great a d v a n t a g e to be able to make use of the labours of so m a n y men . . . B u t at the same time there is a considerable d a n g e r that if we study these works too closely traces of their errors will infect us and cling to us against our will and despite our precautions" ( C S M I , I 3 ) . In the late Principles
he says that "Since
we began life as infants, and m a d e various j u d g m e n t s concerning the things that can be perceived by the senses before w e had the full use of our reason, there are m a n y preconceived opinions (praejudicia)
that
keep us from knowledge of the truth" (i,i; C S M 1 , 1 9 3 ) . S o as w e prepare to engage in scientia,
w e need to be cured of the disease of
mistaken preconceptions as to the locus of certitude. In his reply to Gassendi's objections to the Meditations,
Descartes emphasized the
difficulty of the cure: 1 0
Also, I should add, in his recommendation that w e follow the rule of analysis as we attempt to arrive at propositions on which intuition can go to work.

You say that you approve of my project for freeing my mind from preconceived opinions (praejudicia); and indeed no one can pretend that such a project should not be approved of. But you would have preferred me to have carried it out by making a "simple and brief statement" - that is, only in a perfunctory fashion. Is it really so easy to free ourselves from all the errors which we have soaked up since our infancy? Can we really be too careful in carrying out a project which everyone agrees should be performed? (CSM 11,241-2) T h e cure Descartes recommends is the T h e r a p y of D o u b t , to which I referred in the last section of C h a p t e r
1 . H e r e is one of his
well-known recommendations of it: In order to philosophize seriously and search out the truth about all the things that are capable of being known, we must first of all lay aside all our preconceived opinions, or at least we must take the greatest care not to put our trust in any ol the opinions accepted by us in the past until we have first scrutinized them afresh and confirmed their truth. Next, we must give our attention in an orderly way to the notions that we have within us, and we must judge to be true all and only those whose truth we clearly and distinctly recognize when we attend to them in this way. (Principles1,75; C S M 1,221) T h e l a n g u a g e Descartes uses in this passage suggests that the T h e r a p y of D o u b t is not the M e t h o d , but rather a therapeutic discipline to be undertaken before one can use the M e t h o d satisfactorily." (Cf. C S M 1 1 , 2 7 0 , last p a r a g r a p h ; and C S M 1 1 , 3 2 4 . ) In other passages Descartes speaks as if the T h e r a p y and the M e t h o d were identical (see especially C S M 1 1 , 4 0 7 ) . I j u d g e that a coherent interpretation requires that we treat them as distinct. T h e most decisive consideration is this: I f w e are
apprehending, say, certain mathematical propositions clearly
and distinctly, the M e t h o d tells us that w e are allowed to accept them, whereas (as w e shall see) the T h e r a p y instructs us to doubt them. The
history of Descartes-interpretation makes it a b u n d a n t l y clear
that Descartes invites being interpreted as holding that the goal of the Therapy is to free the mind from almost all assent
to v a c u u m it of
almost all belief. I f there were not that history, based on
that
a m b i g u i t y , I could at this point halt m y discussion of Descartes and move on. T h a t will not be possible. I shall have to argue that emptying the mind of almost all assent is not at all w h a t Descartes " T h o u g h 1 do not entirely agree with his understanding of the character and role of intellectual therapy in Descartes's thought, someone who has seen the importance of its role, especially in the Meditations, is Mike Marlics, "Doubt, Reason, and Cartesian T h e r a p y , " in Michael Hooker (ed.), Descartes: Critical and Interpretive Essays (Baltimore, J o h n s Hopkins Press, 1 9 7 8 ) , pp. 8 9 - 1 1 3 .
Locke's

thinks necessary for practicing scientia
successfully; it is not
an
e n d e a v o r he ever recommended - if for no other reason than that he thought it had no c h a n c e whatsoever of succeeding. Indeed, I j u d g e the traditional interpretation to be so entrenched that I shall h a v e to go further yet and sketch the outlines, at least, of an alternative interpretation of w h a t Descartes understood the goal of the T h e r a p y to be. T h e r e is a hermeneutical issue w h i c h is unavoidable at this point. It would be easy to cite passages in which Descartes speaks about doubt with words whose "plain sense" does not fit m y interpretation of w h a t he has in mind by doubt. It is from that "plain sense" that others have developed their different understandings of Cartesian doubt. S o w h a t leads me to violate that "plain sense"? T w o considerations. I do not see how the "plain sense" interpretation can be fitted into an overall interpretation of Descartes which makes sense of his total project; and I propose that w e prefer an interpretation which does make sense of his total project to one which does not. Secondly, and m u c h more importantly,
I think
that w e ought
to follow
Descartes's
own
guidelines as to the interpretation of such passages. In his letters, and especially in his replies to the objections to the Meditations, repeatedly calls attention
Descartes
to certain general indications
he
has
planted in the text as to the nature of his project; he insists that these indications be treated as guidelines in interpreting his text. It turns out that following those guidelines often requires that we not go by the "plain sense of the text." Descartes regularly accuses his critics of ignoring the guidelines and
though he would not put it this w a y
of
going instead by the "plain sense." I propose that w e do follow Descartes's guidelines for the interpretation of his o w n texts; I think that il would be perverse not to do so, unless w e have some indication that the stated guidelines are self-serving or deceptive. O f course the trouble arises from the fact that though Descartes wishes his texts to be interpreted in a c c o r d a n c e with his guidelines, he himself seems to h a v e composed a good deal of them without h a v i n g those guidelines clearly in mind. I f he had composed all of them with the guidelines clearly in mind, the "plain sense" interpretation would not
so
regularly be in tension with the interpretation which follows the guidelines, forcing us to decide which is to be preferred.

freeing ourselves from these opinions is to make the effort, once in the course of our life, to doubt everything w h i c h w e find to contain even the smallest suspicion of uncertainty." T h e n , a d d i n g w h a t a l r e a d y his original readers thought to be overkill, he says: "Indeed, it will even prove useful, once w e h a v e doubted these things, to consider them as false, so that our discovery of w h a t is most certain and easy to know may
be all the clearer" ( C S M 1 , 1 9 3 ) . H e goes on to say that, as the
first step in the T h e r a p y of D o u b t , "our initial doubts will be about the existence of the objects of sense-perception and imagination. T h e first reason for such doubt is that from time to time w e h a v e c a u g h t out the senses when they were in error, and it is prudent never to place too m u c h trust in those w h o have deceived us even once. T h e second reason is that in our sleep w e regularly seem to h a v e

perception of, or to imagine, countless things which do not exist a n y w h e r e ; and if our doubts are on the scale just outlined, there seem to be no marks by means of w h i c h w e can with certainty distinguish being asleep from being a w a k e " ( C S M 1 , 1 9 3 - 4 ) . Yet,
in the Synopsis to the Meditations
Descartes says, about the
arguments offered in the Sixth Meditation for "the existence
of
material things," that "the great benefit of these arguments is not, in my
view, that they prove w h a t they establish
namely that there
really is a world, and that h u m a n beings have bodies and so on
since
no sane person has ever seriously doubted these things" ( C S M
11,11).
In his reply to Gassendi's objections to the Meditations
he repeats the
point: " H e n c e I point out in one passage that no sane person ever seriously doubts such things" ( C S M 1 1 , 2 4 3 ) . H e r e , then, is the question which every interpretation of Descartes must face rather than avoid: Descartes says that as the first step in the T h e r a p y of D o u b t , the therapy w e must undertake so as to become able to a p p l y the M e t h o d satisfactorily in the construction of scientia, we are to doubt the testimony of our senses that there is a material world. H e makes clear that he views himself as h a v i n g done this. Y e t he also asserts emphatically that no sane person has ever seriously doubted these things; obviously he takes himself to be a sane person. W h a t are w e to make of this? I submit that unless w e attribute the most appalling confusion to Descartes, w e must interpret him as h a v i n g two different things in mind by "doubt." W e can get at the same issue from a somewhat different angle. T o engage in the T h e r a p y of D o u b t , let us remind ourselves, "is to make the effort, once in the course of our life, to doubt everything w h i c h w e

find to contain even the smallest suspicion of uncertainty." I t consists of "rejecting everything in w h i c h I could discover the least occasion for doubt; for it is certain that principles w h i c h it was impossible to reject in this w a y , when one attentively considered them, are the clearest and most evident that the h u m a n mind can k n o w " ( C S M 1,183). B Meditations,
u
t
in his replies to the S e c o n d Set of Objections to the Descartes says that " I should like you to r e m e m b e r here
that, in matters w h i c h m a y be e m b r a c e d by the will, I m a d e a v e r y careful distinction between the conduct of life and the contemplation of the truth. A s far as the conduct of life is concerned, I a m very far from thinking that w e should assent only to w h a t is clearly perceived. O n the contrary, I do not think that w e should a l w a y s wait even for probable truths" ( C S M 1 1 , 1 0 6 ) . B u t of course w e cannot divide up propositions into two disjunct sets, those w h i c h in the conduct of life we decide whether or not to accept, and those w h i c h in the practice of scientia w e decide whether or not to accept. T h e very propositions which for the conduct of life w e must believe, for the contemplation of the truth, w e must doubt. Neither is it the case that doubting and not doubting such propositions can be performed sequentially; since while a person is engaged in the contemplation of truth, he or she is also engaged in the conduct of life. W h i l e doubting that there is a n y t h i n g solid, as part of his or her contemplation of truth, a person must believe that he or she is seated on something solid. The c o n d u c t of life is not something one leaves behind as one contemplates the truth. T h e conduct of life embraces one's contemplation of the truth. Perhaps if w e try to recover w h a t Descartes's experience would have been as he prepared to use the M e t h o d , w e can discern w h a t he has in mind. T o get going, he must sort out the certain from the uncertain. S o he asks himself: T h e s e beliefs of mine, based
on
perception and to the effect that there is this and that material object do these beliefs h a v e the requisite status of certitude? H e has reason to think that they do not. T h o u g h up to this time he m a y h a v e taken them as certain, that would h a v e been a false praejudicium;

shows that they are not indubitable. B u t d r a w i n g this conclusion does not remove these beliefs from Descartes's mind. H e still has them.

I suggest that it is exactly this d o u b t w h i c h figures in the T h e r a p y . Cartesian d o u b t is indeed suspension of assent. B u t to " d o u b t " P, as part of the T h e r a p y of D o u b t , is not to suspend one's belief that P but rather to suspend one's belief that one's mode of a p p r e h e n d i n g P is satisfactory for scientia. It is to suspend one's belief (if one h a d it) that P is certain for one. Cartesian d o u b t is second-order doubt: m c t a - d o u b t . It is not doubting those beliefs that play a role in the conduct of life, nor is it doubting those beliefs that play a role in the practice
of
religion.
Neither is it suspending a n y second-order beliefs one might h a v e about the satisfactoriness of those beliefs for the conduct of life or for the practice of religion. Nonetheless, it does involve Cartesianly
doubting
all the believings that o c c u r in the conduct of life and in the practice of religion - doubting that they are satisfactory for scientia,
doubting
that they are the product of intuition a n d / o r deduction. T o say it again: " D o u b t i n g " a proposition, when e n g a g i n g in the T h e r a p y , is not withholding assent from it but withholding assent from the proposition that one's mode of entertaining it has the epistemic status needed for scientia: certainty, marked by indubitability and incorrigi bility. Descartes never gives up his belief that there is an external world; neither, contrary to the great majority of his interpreters, does he think that he or a n y o n e else should give it up. In fact he thinks that not h a v i n g that belief is a mark of insanity. T h e "greatest benefit" of "such extensive d o u b t , " says Descartes, "lies in freeing us from all our preconceived opinions (praejudicia),
and providing the easiest route by
which the mind m a y be led a w a y from the senses" (Synopsis of the Meditations; C S M 1 1 , 9 ) . T h i s is not to say, of course, that Descartes thinks that the beliefs w e presently h a v e are all O K . Quite to the contrary; he thinks that they are
riddled with error. B u t the task of dislodging those erroneous
beliefs is not assigned to the T h e r a p y of D o u b t . T h e task of dislodging into a tabula rasa, and the skepticism to which he commits himself is innocuously thin and undisruptive. Indeed it is inappropriate to describe it as skepticism at all. Consider the example of a mathematician who is, let us say, attempting to construct a system of arithmetic. If he has so far failed or neglected to establish that '2 + 2 — 4' is a theorem of his system, he will quite properly refuse to assume in his inquiry that the equation is true. T h i s is hardly a case of skepticism, and it would be inane to argue, as it has been argued occasionally against Descartes, that the mathematician's refusal is insincere or that his project is absurd because it is psychologically impossible for him to cease believing that 2 + 2 = 4. The mathematician continues, of course, to 'believe' the equation, but he does not accord it a place in the system he is developing because it has not yet passed the tests for inclusion. Within the context of his theoretical work in arithmetic, then, he docs not yet 'believe' that 2 + 2 = 4. W'hen he undertook his work he 'overthrew' all such beliefs in the limited sense that he decided not to take their theoretical credentials for granted" (Demons, Dreamers, and Madmen, pp. 1 6 - 1 7 ) .

our mistaken scientific beliefs falls to the construction of a new and better science; the task of dislodging our mistaken
philosophical
beliefs falls to the construction of a new and better philosophy; and so on. In the Sixth M e d i t a t i o n , Descartes gives detailed
arguments
against our present understanding of the nature of the external world and in favor of an alternative understanding. B u t let us not live with the illusion that the T h e r a p y is easy and pleasant, says Descartes. It is in fact "an arduous undertaking, and a kind of laziness brings me back to normal life. I a m like a prisoner w h o is enjoying an i m a g i n a r y freedom while asleep; as he begins to suspect that he is asleep, he dreads being woken up, and goes along with the pleasant illusion as long as he can. In the same w a y , I happily slide back into my old opinions and dread being shaken out of them, for fear that my peaceful sleep m a y be followed by hard l a b o u r when I wake, and that I shall h a v e to toil not in the light, but amid the inextricable darkness of the problems I have now raised" (First Meditation; C S M 1 1 , 1 5 ) . Descartes hints, in that last clause, that the T h e r a p y is not only arduous but menacing in prospect. H e opens his Second Meditation on this theme of menace: " S o serious are the doubts into w h i c h I h a v e been thrown as a result of yesterday's meditation that I can neither put them out of m y mind nor see a n y w a y of resolving them. It feels as if I have fallen unexpectedly into a deep whirlpool w h i c h tumbles me around so that I can neither stand on the bottom nor swim up to the top" (Second Meditation; C S M 1 1 , 1 6 ) . P r o b a b l y no one likes to h a v e one's praejudicia,
concerning w h a t is
and isn't certain for one, disturbed; the T h e r a p y of D o u b t will a l w a y s be unpleasant. W h a t makes it menacing, though, is the radically skeptical grounds for doubt that occurred to Descartes. W e are to look around to see whether we can discover any grounds for doubting the certainty of one and another of our beliefs
or rather, of whole types
of belief. A p p a r e n t l y around 1 6 2 8 , after he had composed a good deal of the Rules and before he h a d composed the Discourse,
a truly radical
and menacing ground for doubt occurred to Descartes - perhaps suggested b y the currents of skepticism flowing in F r a n c e at that time. 1 3

M i g h t it be the case that w e are so constituted or influenced
I accept E . M . Curlcy's argumentation on this point, in the second chapter of his Descartes against the Skeptics (Cambridge, Mass., H a r v a r d University Press, 1 9 7 8 ) . It appears that what contributed to Descartes's new line of thought was not just the emergence of his conviction that it was possible for the phenomenology of self-evidence to be evoked by our "intuition" of falsehoods, but the emergence of his conviction that there are no limits on God's omnipotence: W h a t e v e r is false, G o d could have made true, and whatever is

that the experience of a proposition's being self-evident to us, as that w a s traditionally characterized, is in fact (sometimes) evoked b y our "intuition" of falsehoods rather than of truths? W i t h just one crucial c h a n g e in the traditional characterization of that experience: T h e experience of self-evidence was often described as i n c l u d i n g j ^ t seeing that the proposition in question is true. T h a t has to go, to be replaced by the phenomenology of seeming to see that it is true. F o r if one actually sees that it's true, then it is true. I h a v e suggested
that in his understanding of scientia
and its
method, as well as in his insistence on the importance of practicing scientia, Descartes w a s perpetuating a long tradition. His innovations are located in the g r a n d expectations he h a d for the scope of
scientia,
and in the proposals he m a d e for how w e are to prepare ourselves for engaging in scientia. W h a t led to the latter innovations was Descartes's conviction that w e bring with us, to the practice of scientia,
inhibiting
and falsepraejudicia concerning w h a t is and isn't certain for us, due in part, as it turns out, to o u r failure to imagine the truly radical possibilities. L e t it be seen clearly that Descartes's conviction is not that the propositional contents of those believings of ours which w e , in a d v a n c e of practicing scientia, believe to be certain, are false.
Though
he did think that a good deal of w h a t is read in texts is false - the vision of a textual tradition whose deep content is an articulated unity was no longer alive in him
he regarded the beliefs that w e bring with us
from experience (and religion) as in great measure true. T h e false and debilitating praejudicia from which w e must be liberated arc second-order beliefs about the certainty of our believings. T h o u g h Descartes was c a r r y i n g on project of scientia,
the medieval
Aristotelian
n o b o d y in the medieval tradition had suggested
a n y t h i n g like Descartes's T h e r a p y of D o u b t as the appropriate preparation for e n g a g i n g in the project. Nonetheless,
the
points
Descartes has raised are not ones that a person in that tradition could dismiss out of h a n d . E v e n if one believes (as Descartes did not) that the textual tradition presents an articulate unified b o d y of truth, it must be conceded that in great measure it does not present that truth in the mode of knowledge but in the mode of opinion, and usually without a n y clear demarcation of the one from the other; accordingly, immersing oneself in those texts is indeed likely to inculcate in one true, G o d could have made false. But though this conviction is usually in the wings when Descartes sets forth his radical ground for doubt, it is not really essential to it; the evil genius might be doing its devilish work even though G o d was not thus omnipotent.

mistaken convictions as to w h a t one is certain of. A n d as to the status of "intuition": T h e possibility that the phenomenology of self-evidence be evoked b y falsehoods is something that has to be considered. W a s Descartes of the view that his contemporaries were peculiarly prone to those false inhibiting praejudicia?
W e l l , in Part I of the
Discourse he certainly makes clear his conviction that scientia in his day was in a state of severe crisis; and the wanderings he describes in that same part, as well as his o w n subsequent controversies, immersed him in the religious turmoil of E u r o p e . Nonetheless, T h e r a p y is meant to cure is a human disease.

B u t the disease is present in a n y o n e w h o has sensory experience and reads books; and it works its debilitating effects on a n y o n e w h o sets about trying to practice scientia. L e t me summarize the central points I h a v e been making: T h e M e t h o d does not tell us to dissent from everything which is not the result of intuition and deduction. W e cannot do that, says Descartes, nor should w e try. The M e t h o d is rather a method for the acquisition of apprehensions w h i c h are purely the p r o d u c t of intuition
and
deduction; it is a method for the building up of true scientia. B u t since mistaken prejudgments, as to which of one's apprehensions are certain for one, will get in the w a y of satisfactory practice of the M e t h o d , the T h e r a p y of D o u b t is to be undertaken so as to clear a w a y those confusions.

T h i s certainly fits with what Descartes says near the end of the First Meditation, as he is bringing the process of doubting to its conclusion : "I . . . am finally compelled to admit that there is not one of my former beliefs about which a doubt may not properly be raised; and this is not a flippant or ill-considered conclusion, but is based on powerful and well thought-out reasons" ( C S M

I f one were to h a v e a good reason for Cartesianly d o u b t i n g propositions thus a p p r e h e n d e d , it would h a v e to be a reason for refraining from believing that such apprehensions are incorrigible.
For
we are now past the point of dubitability. I f one apprehends a proposition clearly and distinctly, then one's situation couldn't be that of h a v i n g good reason to refrain from believing it. " W h a t e v e r is revealed to me b y the natural l i g h t . . . cannot in a n y w a y be open to doubt. T h i s is because there cannot be another faculty both as trustworthy as the natural light and also c a p a b l e of showing me that such things are not true" (Meditations

O f course, Descartes is assuming here that by the natural light w e can never intuit or demonstrate both a proposition and its contradictory. I f that could happen, then one could be in a situation where one both apprehended a proposition clearly and distinctly and had good reason to refrain from believing it (not, of course, to believe its c o n t r a d i c t o r y ) . Still, this question arises: M i g h t an apprehension w h i c h is rationally indubitable nonetheless be an apprehension of a proposition which is false? T h e scenario of the evil genius is designed to show that this could be, so far as one can tell at this point. (Descartes offers other, less arresting, scenarios for the same possibility.) I f it is logically possible that there be such an evil genius, then it is logically possible that the rationally indubitable be false. A n d as long as w e don't find it indubitable that such an evil genius is logically impossible, just so long is it also not
rationally indubitable
for us that
the
rationally
indubitable is incorrigible. A n d so, of course, not rationally indubitable that the rationally indubitable is certain. J u s t as w e are to imagine the demon as altering nothing in the p h e n o m e n a of rational dubitability/indubitability, so also w e are to imagine him as altering nothing in the p h e n o m e n a of psychological dubitability/indubitability. T h e L a w of Assent continues to operate. T h u s it is that Descartes exclaims in the T h i r d Meditation: "when I turn to the things themselves w h i c h I think I perceive very clearly, I a m so convinced by them that I spontaneously declare: let w h o e v e r c a n do so deceive me, he will never bring it about that I a m nothing,

so long as I continue to think I a m something; or make it true at some future time that I h a v e never existed, since it is not true that I exist; or bring it about that two and three added together are more or less than five, or a n y t h i n g of this kind in which I see a manifest contradiction" ( C S M 11,25). W h e t h e r or not the Meditations
are unclear as to how far Descartes
wishes to press the question of incorrigibility, Principles
1,5 is entirely
clear on the matter: H e wishes to press it for clear and distinct apprehensions w h i c h compel belief - thus for those apprehensions w h i c h are rationally and psychologically indubitable. H e wishes to press it, in short, for all apprehensions and believings. T h e fact that m y attention to a proposition is so clear and distinct that I cannot refrain from believing it and can h a v e no good reason for doubting it while
thus a p p r e h e n d i n g
it is a p p a r e n t l y compatible
with
the
falsehood of the proposition thus apprehended. W e can imagine a scenario a c c o r d i n g to which this is how things would be. H e n c e w e should
at this point
in our reflections
Cartesianly doubt
such
apprehensions; i.e., refrain from believing that those apprehensions are certain, refrain from believing that they are satisfactory for the construction of scientia. F o r certainly, remember, requires incorrigibility as well as indubitability. O u r doubt will also apply to other matters which we previously regarded as most certain even the demonstrations of mathematics and even the principles which we hitherto considered to be self-evident. O n e reason for this is that we have sometimes seen people make mistakes in such matters, and accept as most certain and self-evident things which seemed false to us. Secondly, and most importantly, we have been told that there is an omnipotent G o d w h o created us. N o w we do not know whether he m a y h a v e wished to make us beings of the sort w h o are a l w a y s deceived even in those matters which seem to us supremely evident; for such constant deception seems no less a possibility than the occasional deception which, as we have noticed on previous occasions, does occur. W e may of course suppose that our existence derives not from a supremely powerful G o d but either from ourselves or from some other source; but in that case, the less powerful we make the author of our coming into being, the more likely it will be that w e are so imperfect as to be deceived all the time. ( C S M 1, 1 9 4 ) ' 5
It is passages such as this which persuade me that Descartes's concept of certainty cannot be explicated entirely in terms of indubitability; incorrigibility is also necessary for certainty. For neither here nor anywhere else does Descartes suggest that he has reason to refrain from believing that clear and distinct apprehensions are indubitable; w h a t he suggests is that, at this stage in his reflections, he has reason to refrain from believing that they are incorrigible but hence, reason to refrain from believing that they are certain.

Descartes rightly says that the second possibility raised is more i m p o r t a n t than the first. W e do indeed make mistakes in w h a t w e take to be self-evident. B u t someone might insist that such mistakes can a l w a y s be explained as the result of our failure to take a c c u r a t e note of the
presence or absence
of the
phenomenology
of clarity and
distinctness. T h e second possibility is the truly serious one: S o far as one can tell at this point, it seems quite possible that there be something in our constitution, or some outside agent, bringing it about that w e experience the phenomenology
of intuition
and
deduction with respect to false propositions. But now the T h e r a p y of D o u b t , introduced as preparation for e n g a g i n g in the M e t h o d satisfactorily, threatens the M e t h o d itself—or strictly, the assumptions underlying the M e t h o d . F o r T h e M e t h o d tells us that if w e are a p p r e h e n d i n g a proposition so clearly and distinctly
that w e
cannot
refrain from
believing it,
and
more
importantly, so clearly and distinctly that w e couldn't h a v e a good reason for doubting it while thus apprehending it has psychological,
if our apprehension
but more importantly, rational indubitability - then it
can be regarded as satisfactory for scientia. T h e n our apprehension is to be taken as certain. B u t now w e h a v e discovered that we, at this point in our reflections, h a v e good reason to refrain from believing that this is correct. F o r even though such apprehensions be indubitable in both senses, w e h a v e good reason to refrain from believing that they are also incorrigible.
But if not incorrigible, then not certain. T h u s at
this point in the a r g u m e n t w e h a v e good reason to refrain from believing that following T h e M e t h o d will yield
scientia.
A n d if w e h a v e good reason to d o u b t that the M e t h o d yields scientia, then it doesn't yield scientia.
This shows, of course, h o w Descartes
understands the nature of scientia
shows that he is attaching a
qualification to the traditional Aristotelian medieval understanding ol scientia. N o t h i n g has been said to show that indubitability does not coincide with incorrigibility. F o r all w e know at this point,
a
systematic pursuit of indubitability might in fact yield believings w h i c h are a l w a y s true
hence fully certain. B u t we would still not
h a v e scientia. " T h e fact that an atheist can be 'clearly a w a r e that the 3 angles of a triangle are equal to 2 right angles' is something I do not dispute. But I maintain that this awareness (cognitio) of his is not true knowledge (scientia),
since no act of awareness (cognitio) that c a n be

A n d even if it be the case that all clearly and

" T h a t is w h a t Descartes proceeds to try to do
to remove
this doubt. H o w can that be done? Well, as w e all know, Descartes proposes to do so by a r g u i n g for the existence of an all-powerful, all-knowing, all-good G o d , and then inferring that G o d would see to it that w h a t e v e r w e apprehend clearly and distinctly is true. But all that w e can make use of in this a r g u m e n t is phenomena that the evil genius would not c h a n g e
if there were an evil genius. T h e evil genius would
not c h a n g e any of the facts about dubitability and indubitability. T h e L a w of Assent would still be operative: W e still find
ourselves
compelled to believe propositions w h i c h w e apprehend with a certain high degree of clarity and distinctness. A n d w e still find that no w a y of apprehending propositions

Cf. Descartes's tetter to Regius of M a y Q4, 1 6 4 0 . Distinguishing scientia from conviction, he says: " I distinguish the two as follows: there is conviction when there remains some reason which might lead us to doubt, but knowledge [scientia] is conviction based on a reason so strong that it can never be shaken by any stronger reason" ( C S M 1 1 1 , 1 4 7 ) .

the course of the argument: that the cause of an idea has at least as much formal
reality as the idea has objective reality. L e t us, for convenience' sake,
call this proposition P. I dare say that most of us do not find P compelling even when w e do clearly and distinctly apprehend it; but that, for our purposes, is neither here nor there. T h e question I must ask myself, as I contemplate whether or not to set P d o w n as part of the a r g u m e n t , is whether I find myself compelled to believe P w h e n I grasp it well. I f I do, then I set it d o w n . Suppose that I a m like Descartes and do find myself compelled to believe this; accordingly, I set it d o w n . B u t now somebody whispers in m y ear: " D o you find yourself compelled
to believe
this other proposition,
that if you
apprehend P so clearly and distinctly that you cannot doubt it, then P is true?" M y answer to this question, at this stage of the a r g u m e n t , is N o . B u t the fact that m y answer is N o , at this stage of the argument, is irrelevant. I suggest, in short, that Descartes's strategy for " r e m o v i n g the doubt" is to construct an argument which satisfies these two conditions: (1)
It has for its conclusion that a n y proposition apprehended so clearly and distinctly as to be rationally (and psychologically) indubitable is necessarily also true, i.e., incorrigible; and
(2) Its premises, and the proposition that the premises entail the conclusion, are apprehended so clearly and distinctly as to be rationally (and psychologically) indubitable. O n c e Descartes has freed us from d o u b t i n g the general thesis, that a n y proposition
apprehended so clearly and distinctly as to be
rationally and psychologically indubitable is true, then he has also freed us from doubting, concerning some particular proposition P w h i c h is apprehended so clearly and distinctly that it cannot be doubted, that P is true. S u p p o s i n g that an a r g u m e n t w h i c h satisfies these conditions can be found, its import remains to be clarified. B u t counter to the charges which have haunted Descartes's Meditations ever since their publication, there is nothing circular or question-begging either in the a r g u m e n t proper or in Descartes's strategy as a whole. W h e n one clearly and distinctly focuses on the a r g u m e n t presented, the conclusion
that
clarity and distinctness of apprehension insures truth of the proposition apprehended is both rationally and psychologically
indubitable:
Descartes claims to h a v e given an a r g u m e n t of that sort. His failure lies simply in the fact that his a r g u m e n t is not of that sort. It is not indubitable; it is not compelling; it does not satisfy the

condition a b o v e . A l m o s t no one has thought that it does, other than Descartes himself. Previously I sketched a scenario according to w h i c h w e could h a v e the phenomenology of clarity and distinctness (and compelled assent) with respect to falsehoods. It w a s the scenario of the powerful demon. U n d e r the scenario, w e are still compelled to believe propositions when w e apprehend them clearly and distinctly. B u t the scenario enabled us to doubt, both in general and for specific cases, w h e t h e r there is a n y necessary connection between indubitability and truth. Now,

able to believe that scenario, or a n y other similar scenario; w e find ourselves compelled to believe that such scenarios are impossible. W e cannot believe that there can be such a demon and

C a n one now once again refrain from accepting its conclusion

not if one remembers that

Neither can one now d o u b t the truth of particular propositions which one remembers having demonstrated clearly and distinctly: " E v e n if I am no longer attending to the arguments which led me to j u d g e that this is true, as long as I r e m e m b e r that I clearly and distinctly perceived it, there are no counter-arguments which can be a d d u c e d to make me doubt it, but on the c o n t r a r y I h a v e true and certain knowledge of it. A n d I h a v e knowledge not just of this matter, but of all matters which I r e m e m b e r ever h a v i n g demonstrated, in geometry, and so on. F o r w h a t objections can now be raised?"

Cf. R e p l y to the Second Set of Objections to the Meditations, G S M 11,104: "But we forget the arguments in question and later remember simply the conclusions which were deduced from them. T h e question will now arise as to whether we possess the same firm and immutable conviction concerning these conclusions, when we simply recollect that they were previously deduced from quite evident principles (our ability to call them 'conclusions' presupposes such a recollection). M y reply is that the required certainty is indeed possessed by those whose knowledge of G o d enables them to understand that the intellectual faculty which he g a v e them cannot but tend towards the truth."

I h a v e emphasized Descartes's introduction of the T h e r a p y of D o u b t as a strategy for getting rid of the mistaken praejudicia
that
hinder us in the practice of scientia. Pretty clearly, though, Descartes saw the T h e r a p y , w h e n combined with the Meditations
a r g u m e n t , as
serving another purpose as well; namely, the polemical purpose of beating the skeptic at his o w n g a m e . Descartes regards himself as h a v i n g brought his readers to the point w h e r e they can no longer doubt, either rationally or psychologically, the things that the skeptic says are questionable. M o r e than that, the Meditations

following on the radical practice of the Discipline, plays the constructive role of making it indubitable that the M e t h o d is satisfactory for the construction of scientia. foundations of scientia.
It is meant, in that w a y , to "establish" the ( O f course, the Meditations
a r g u m e n t itself is
meant to satisfy, formally, at least the first rule of the M e t h o d . ) It m a y be added that, in turn, Descartes saw the M e t h o d not only as the best strategy for building up scientia, but also as yielding a "critique" of those of our assent-forming faculties other than intuition and deduction. W e discover, for e x a m p l e , that perception informs us about reality only to a limited extent. W e must b e w a r e , though, of conceding to Descartes's a r g u m e n t more significance than it actually has. In the course of the early stages of the a r g u m e n t in the Meditations,
which culminates in the affirmation
of the principle that the phenomenology of clarity and distinctness (and of compulsion to believe) is a g u a r a n t e e of truth, Descartes observes that the cogilo ergo sum is impervious to the wiles of the evil genius. It is impossible that one should be compelled to believe this when it is false. The indubitable is here incorrigible. S u p p o s e that "there is a deceiver of supreme power and cunning w h o is deliberately and constantly deceiving me. In that case I too undoubtedly exist, if he is deceiving me; and let him deceive me as m u c h as he c a n , he will never bring it about that I am nothing so long as I think that I am something" ( C S M 1 1 , 1 7 ) .

T o get to (B) from ( A ) w e need a principle of elimination: Compelled-P Therefore, P. But Descartes's a r g u m e n t does nothing to entitle us to this principle.

T h u s you and I w a n t to say that Descartes's a r g u m e n t , if successful, would do no more than display "a d e m a n d of thought." O f all the commentators on Descartes, Frankfurt is the one w h o has seen most clearly this " K a n t i a n " import of the a r g u m e n t . Descartes's a r g u m e n t , he says, is an attempt to show that there are no good reasons for believing that reason is unreliable that the mistrust of reason is not supported by reason and that it is accordingly irrational. . . The point of Descartes's validation of reason is that if reason is properly employed - that is, if we give assent only to what we clearly and distinctly perceive — we are not led to doubt that reason is reliable. We are led, on the contrary, to assent to the propositions that God exists and that He guarantees the reliability of reason . . . no proposition entailing the unreliability of reason can be clearly and distinctly perceived.' 9
W h a t must be noted, however, is that y o u r and m y conviction that (B) does not follow from ( A ) , and that ( C ) is compatible with ( A ) , reflects the fact that we d o not find the a r g u m e n t compelling; correspondingly, our conviction that the a r g u m e n t , if successful, would merely display a " d e m a n d of thought," reflects the fact that you and I do not find the a r g u m e n t compelling. W e find ourselves entirely c a p a b l e , with the a r g u m e n t before us, of doubting
its
conclusion. B y contrast, if w e did find the a r g u m e n t compelling, w e would not believe that ( C ) is compatible with ( A ) . 1 8

S o w e must not expect to find Descartes conceding
that his
a r g u m e n t is nothing but a d e m a n d of thought. H e w a s , indeed, looking for a d e m a n d of thought; that is w h a t he needed at this point in the a r g u m e n t . B u t h a v i n g , in his j u d g m e n t , found it, he naturally enough does not believe that it is merely a d e m a n d of thought. Nonetheless, there is a fascinating passage in the S e c o n d Set of Replies in w h i c h , amidst a lot of bluster, Descartes is quite clearly giving expression to some unease over the import of the argument: as soon as we think that we correctly perceive something, we are spontaneously convinced that it is true. Now if this conviction is so firm that it is impossible for us ever to have any reason for doubting what we are convinced of, then there are no further questions for us to ask: we have everything that we could reasonably want. What is it to us that someone may make out that the perception whose truth we are so firmly convinced of may appear false to God or an angel, so that it is, absolutely speaking, false? W h y should this alleged "absolute falsity" bother us, since we neither believe in it nor have even the smallest suspicion of it? . . . It is . . . no objection for someone to make out that such truths might appear false to God or to an angel. For the evident clarity of our perceptions does not allow us to listen to anyone who makes up this kind of story. ( C S M 1 1 , 1 0 3 - 4 ) M y contention throughout has been that Descartes's main concern was scientia,
or as he tends to call it in his later writings, "the
contemplation
of the truth." T h e M e t h o d is a method
for the
construction ofscientia. A n d w h a t I h a v e called the T h e r a p y of D o u b t is, first of all, a therapy lo be undertaken so that w e can practice the M e t h o d satisfactorily. W h e r e a s the center of Locke's concern was to give us rules for the regulation of opinio, Descartes, for opinio, gives us nothing more than a few limited, bland, and thoroughly conventional pieces of advice. It would a p p e a r , however, that this interpretation is in flagrant conflict with w h a t Descartes says in the Fourth Meditation. F o r there, in the context of inquiring how error in h u m a n belie! is compatible with the existence of an omnipotent, omniscient, benevolent G o d , he says that " I f . . . I simply refrain from m a k i n g a j u d g m e n t in cases where
I do
not
perceive
the
truth with sufficient
clarity and
distinctness, then it is clear that I a m b e h a v i n g correctly and a v o i d i n g error. B u t if in such cases I either affirm or deny, then I a m not using m y free will correctly" ( C S M 1 1 , 4 1 ) . H e adds: " F o r it is surely no imperfection in G o d that he has given me the freedom to assent or not to assent in those cases where he did not endow m y intellect w i t h a
Locke's

originality
clear and distinct perception; but it is undoubtedly an imperfection in me to misuse that freedom and m a k e j u d g e m e n t s about matters w h i c h I do not fully understand" ( C S M 1 1 , 4 2 ) . Descartes gives no indication here that these claims are restricted to scientia. H e appears to be claiming, in general, that if one assents to some proposition w h i c h one has not perceived with full clarity and distinctness, then one is misusing the faculties G o d has given one. But
if this w e r e in fact the right interpretation, Descartes would
regard himself and every other sane person as violating this fundamental h u m a n obligation. F o r , as w e h a v e seen, he thinks that every sane person believes various existential propositions about material bodies, even though these are not apprehended clearly and distinctly. S o I think that the proper interpretation requires that w e take with full seriousness the explanations and disclaimers that Descartes makes in his reply to the S e c o n d Set of Objections to the Meditations.
I have
already quoted part of the passage. L e t me now quote the whole of it: I should like you to remember here that, in matters which may be embraced by the will, 1 made a very careful distinction between the conduct of life and the contemplation of the truth. As far as the conduct of life is concerned, I am very far from thinking that we should assent only to what is clearly perceived. On the contrary, I do not think that we should always wait even for probable truths; from lime to time we will have to choose one of many alternatives about which we have no knowledge, and once we have made our choice, so long as no reasons against it can be produced, we must stick to it as firmly as if il had been chosen for transparently clear reasons. I explained this on p. 26 of the Discourse on the Method. For when we are dealing solely with the contemplation of the truth, surely no one has ever denied that we should refrain from giving assent to matters which we do not perceive with sufficient distinctness. Now in my Meditations I was dealing with the contemplation of the truth; the whole enterprise shows this to be the case, as well as my express declaration at the end of the First Meditation where 1 said that I could not possibly go too far in my distrustful attitude, since the task in hand involved not action but merely the acquisition of knowledge. ( C S M 1 1 , 1 0 6 ; see also Fourth Set of Replies; C S M 1 1 , 1 7 2 , and Fifth Set of Replies; C S M 11,243) W e should assent to P as satisfactory for scientia only if it is clearly and distinctly apprehended. B u t w h a t , you ask, about our actual assent to P? Believing that P is satisfactory for scientia is different from believing (assenting
to) P. F u r t h e r , it sometimes
turns out that the very
proposition, assent to w h i c h is indispensable for the conduct of life, is not apprehended in such a w a y that I a m entitled to inscribe it in the book of science. D o I then, or do I not, actually assent to P? Descartes

says Y e s . (See, for example, C S M I I , I O 6 . ) Nonetheless, his observations on the matter are seldom
more
than incidental.
T h a t , on
my
interpretation, is no accident. Descartes is simply not m u c h interested in rules for regulating our actual assent to most propositions. H e is interested in acquiring a systematic and productive body of propositions each of which w e know to h a v e been either intuited or deduced from w h a t is intuited. O b v i o u s l y such propositions, w h e n found, will be assented to. B u t there are m a n y other belief-forming faculties than intuition and deduction. S o m e of these others lead us to assent to propositions w h i c h later w e intuit or deduce; some lead us to assent to propositions which w e never do and never can intuit or deduce. In all of that, Descartes had no fundamental interest. T h e r e is another theme
in the F o u r t h M e d i t a t i o n on
whose
compatibility with m y interpretation w e must reflect, the theme of the radical freedom of the will. A key component in m y overall interpretation has been m y claim that Descartes embraces w h a t I have called the L a w of Assent: If one clearly and distinctly apprehends a proposition, it is psychologically impossible to withhold one's assent from it; "our mind is of such a nature that it cannot help assenting to w h a t it clearly c o n c e i v e s . "
20
Is this not incompatible with Descartes's
claim that the will is no more limited in its freedom in h u m a n beings than in G o d ? F o r Descartes held, after all, that for a n y proposition whatsoever, G o d can make it either true or false. In a well-known passage from the Principles
of Philosophy,
Descartes
says that "we possess only two modes of thinking: the perception of the intellect
and the operation of the will"; and he asserted
-
implausibly in m y view - that assenting to a proposition is a species of willing: All the modes of thinking that we experience within ourselves can be brought under two general headings: perception, or the operation of the intellect, and volition, or the operation of the will. Sensory perception, imagination and pure understanding are simply various modes of perception; desire, aversion, assertion, denial and doubt are various modes of willing. (1,32; C S M 1,204) Descartes then held that in every case of belief, both the intellect and the will are involved. W e a p p r e h e n d the proposition with more or less clarity and distinctness; that is a mode of intellect. A n d w e assent to the proposition; that is a mode of volition. " M a k i n g a j u d g m e n t , " he says, "requires not only the intellect but also the will." Letter to Regius, M a y 2 4 , 1 6 4 0 , in K e n n y , Descartes: Philosophical
Letters, p. 7 3 .

In order to make a judgement, the intellect is of course required since, in the case of something which we do not in any way perceive, there is no judgment we can make. But the will is also required so that, once something is perceived in some manner, our assent may then be given. Now a judgement - some kind of judgement at least - can be made without the need for a complete and exhaustive perception of the thing in question; for we can assent to many things which we know only in a very obscure and confused manner. (Principles 1,34; C S M 1,204) C o n c e r n i n g these two fundamental modes of mind, Descartes held that though the h u m a n intellect is limited, in the sense that for every h u m a n being there are m a n y propositions w h i c h are simply beyond the scope of his or her consideration or the p o w e r of his or her grasp, the will is not similarly limited. " I cannot complain," he says, "that the will or freedom of choice which I received from G o d is not sufficiently extensive or perfect, since I know by experience that it is not restricted in any w a y " (Fourth Meditation; C S M 1 1 , 3 9 ) . T h e n he goes on to say: It is only the will, or freedom of choice which I experience within me to be so great that the idea of any greater faculty is beyond my grasp; so much so that it is above all in virtue of the will that I understand myself to bear in some way the image and likeness of God. For although God's will is incomparably greater than mine, both in virtue of the knowledge and power that accompany it and make it more firm and efficacious, and also in virtue of its object, in that it ranges over a greater number of items, nevertheless it does not seem any greater than mine when considered as will in the essential and strict sense. This is because the will simply consists in our ability to do or not do something (that is, to affirm or deny, to pursue or avoid), (fourth Meditation; C S M 11,40) W h a t is it that Descartes is saying here? Perhaps something like this: Suppose
that w e grant that
the object of intentions
and
undertakings is a l w a y s to bring it about that a certain proposition be made true. Intending to get my letter to the box before the m a i l m a n comes amounts to intending to bring about the truth of the proposition that I get my letter to the box before the m a i l m a n comes. N o w , Descartes believes that G o d has entertained and grasped vastly more propositions than any of us has. T h u s there are m a n y more propositions which can be the object of intentions and undertakings on G o d ' s part than on ours. T h e p o w e r of will is i n c o m p a r a b l y greater in G o d than in us "in virtue of its object, in that it ranges over a greater n u m b e r of items." S o also, there are m a n y propositions whose truth G o d knows how to bring a b o u t and has the p o w e r to bring about, but for w h i c h

w e lack either the one or the other, either the knowledge or the power. T h e p o w e r of will is i n c o m p a r a b l y greater in G o d than in us also "in virtue of the knowledge and power that a c c o m p a n y it and make it more firm and efficacious." T h u s G o d can successfully undertake m a n y things that w e cannot. I n these w a y s , G o d ' s will is undeniably, and i n c o m p a r a b l y , more powerful than ours, says Descartes. But these differences do not speak to w h a t the will is "in the essential and strict sense." T h e y speak to differences in knowledge and to differences in p o w e r of implementation. B y contrast, willing
as such involves neither
of these but consists simply in undertaking something;
the will
"consists in our ability to do or not do something." I m m e d i a t e l y , however, Descartes adds a crucial qualification, or explanation, to this last point; an explanation w h i c h makes clear that, for him, freedom of the will consists not of the liberty of indifference but in the liberty of spontaneity. T h i s is w h a t he adds: or rather, the will consists simply in the fact that when the intellect puts something forward for affirmation or denial or for pursuit or avoidance, our inclinations are such that we do not feel we are determined by any external force. In order to be free there is no need for me to be inclined both ways; on the contrary, the more I incline in one direction - either because I clearly understand that reasons of truth and goodness point that w a y , or because of a divinely produced disposition of my inmost thoughts - the freer is my choice. Neither divine grace nor natural knowledge ever diminishes freedom; on the contrary, they increase and strengthen it. But the indifference I feel when there is no reason pushing me in one direction rather than another is the lowest g r a d e of freedom; it is evidence not of any perfection of freedom, but rather of a defect in knowledge or a kind of negation. F o r if I always saw clearly what was true and good, I should never have to deliberate about the right j u d g e m e n t or choice; in that case, although I should be wholly free, it would be impossible for me ever to be in a state of indifference. (Fourth Meditation; C S M 11,40) Descartes's thought appears to be this: If there are sufficient causal conditions for the occurrence of some undertaking, but those sufficient causal conditions include no "external force," then the undertaking is free even though the person could not h a v e chosen otherwise. T h e application to the matter at h a n d of this understanding of freedom is this: Descartes's claim, that w e are all so constituted as to be compelled to assent to propositions that w e clearly and distinctly a p p r e h e n d , is not seen by him as incompatible with his claim that free will is involved in all cases of assent. F o r the compulsion is internal:
Locke's

during these past few days I have been asking whether anything in the world exists, and I have realized that from the very fact of my raising this question it follows quite evidently that I exist. I could not but j u d g e that something which I understood so clearly was true; but this was not because I was compelled so to j u d g e by any external force, but because a great light in the intellect was followed by a great inclination in the will, and thus the spontaneity and freedom of my belief was all the greater in proportion to my lack of indifference. (Fourth Meditation; C S M 1 1 , 4 1 ) 2 1
T h e r e is one exception w h i c h Descartes himself introduced into the M e t h o d - an exception which he seems to h a v e regarded as minor in scope of application but major in import. R e p e a t e d l y Descartes emphasizes that not only is the M e t h o d not meant for the conduct of life; it is also not meant for religious faith: "when I asserted that 'we should assent only to w h a t w e clearly know' this w a s a l w a y s subject to the exception of 'matters w h i c h belong to faith and the conduct of life'" ( C S M 1 1 , 1 7 2 ) . W h e n it comes to faith, the rule is that w e are to accept w h a t is revealed by G o d : "if G o d happens to reveal to us something about himself or others which is beyond the natural reach of our mind
such as the mystery of the Incarnation or of the T r i n i t y
we will not refuse to believe it, despite the fact that w e do not clearly understand it" (Principles Our
1,25; C S M 1 , 2 0 1 ) .
natural perceptual faculties produce in us apprehensions of,
and assentings to, various propositions which we h a v e neither intuited nor
demonstrated. T h a t is quite acceptable, says Descartes. W h a t
must be kept in mind, however, is that none of those apprehensions are good enough for scientia; any praejudicia
we m a y have that these beliefs
are certain must be overcome by the T h e r a p y of D o u b t . F o r the most part, the same is true of religious faith. F a i t h simply involves a different apprehension and belief-forming process from the workings of those faculties of intuition and deduction which yield scientia.
W h a t that
process might be, Descartes tries briefly to explain in his reply to the A hit later Descartes adds: "this indifference does not merely apply to cases where the intellect is wholly ignorant, but extends in general to every case where the intellect docs not h a v e sufficiently clear knowledge at the time when the will deliberates" ( C S M 1 1 , 4 1 ) . C o m p a r e Principles 1,39: "the freedom which we experienced within us was nonetheless so great as to enable us to abstain from believing whatever was not quite certain or fully examined" ( C S M 1,206). A n d also from the Fourth Meditation: " F o r although probable conjectures may pull me in one direction, the mere knowledge that they are simply conjectures, and not certain and indubitable reasons, is itself quite enough to push my assent the other w a y . M y experience in the last few days confirms this: the mere fact that I found that all my previous beliefs were in some sense open to doubt was enough to turn my absolutely confident belief in their truth into the supposition thai they were wholly false" ( C S M 11,41).

( C S M 1 1 , 2 0 5 ) . It is indeed a
process rather than a faculty or mechanism. It consists of G o d directly p r o d u c i n g in us the firm conviction, concerning some proposition P, that G o d has revealed it; given our intuition that G o d cannot lie, that produces in us the belief that P . But
2 2
to limit the scope of the M e t h o d to the practice of scientia is
different from contending that, in the practice of scientia, there m a y be certain cases in w h i c h w e are to employ some other rule than the M e t h o d . B u t that is exactly w h a t Descartes contends. Specifically, if some item of the faith is intuited as contradicting some proposition which is entertained with the phenomenology of clarity and distinctness, and
compelled belief, w e should - or perhaps just shall - prefer the
item of faith. W e should or shall conclude that at this point the phenomenology of clarity and distinctness, and compelled belief, is deceptive, that there is a fluke in the workings of our faculties. W e find ourselves with the belief that G o d has revealed P; but w e apprehend clearly and distinctly, and a r e compelled to believe, both not-P, and that not-P contradicts P. In such a situation, our conviction that G o d has revealed P, plus our standing conviction that G o d cannot lie, should (or will) win out over our intuitions, leading us to believe P. H e n c e " a b o v e all else w e must impress on our m e m o r y the overriding rule that w h a t e v e r G o d has revealed to us must be accepted as more certain than a n y t h i n g else. A n d although the light of reason m a y , with the utmost clarity and evidence, a p p e a r to suggest something different, w e must still put o u r entire faith in divine authority rather than in our own j u d g m e n t " (Principles
1,76; C S M 1 , 2 2 1 ) .
A s I h a v e already suggested, the interpretation of Descartes w h i c h I h a v e presented is unconventional at several points; if that were not 2 2
" N o w although it is commonly said that faith concerns matters which arc obscure, this refers solely to the thing or subject-matter to which our faith relates; it does not imply that the formal reason which leads us to assent to matters of faith is obscure. O n the contrary, this formal reason consists in a certain inner light which comes from G o d , and when we arc supernaturally illumined by it we are confident that what is put forward for us to believe has been revealed by G o d himself. A n d it is quite impossible for him to lie; this is more certain than any natural light, and is often even more evident because of the fight of grace" (Reply to the Second Set of Objections to the Meditations; C S M 1 1 , 1 0 5 ) . Cf. Descartes's letter to Hyperaspistes of August 1 6 4 1 : "In the reply to the Second Objections I said 'enlightened by God, we trust that w h a t is proposed for our belief has been revealed by him': but there I was speaking not of human scientific knowledge, but of faith. A n d I did not assert that by the light of grace we clearly know the very mysteries of faith - though I would not deny that this too may happen — but only that we trust that they are to be believed. N o one w h o really has the Catholic faith can doubt or be surprised that it is most evident that w h a t G o d has revealed is to be believed and that the light of grace is to be preferred to the light of nature."

so, it could, for the purpose of illuminating the relation of Descartes to L o c k e , h a v e been very m u c h a b b r e v i a t e d . Nonetheless, I h a v e not tried to defend it against alternatives but h a v e contented myself with referring to supporting texts and pointing to its overall coherence. In conclusion, though, I wish to consider the alternative interpretation offered by B e r n a r d Williams on the central point of the nature of Cartesian d o u b t .
23
I choose W i l l i a m s as a good representative of a
fairly standard line of interpretation. O n m y interpretation, to Cartesianly doubt some proposition P is not to suspend one's assent to P but rather to suspend one's assent to the proposition that one's mode of apprehending P is satisfactory for the inclusion of P in scientia. T h u s I contend that, to understand Descartes, w e must distinguish between those passages in which b y "doubting" P he means no longer assenting
to P, and those in w h i c h
by
"doubting" P he means Cartesianly doubting P. Williams interprets Descartes as uniformly meaning the same thing by " d o u b t "
namely,
d o u b l i n g P is suspending one's assent to P. H e says that "the method of doubting everything until one reaches, if one c a n , something that cannot be doubted, is presented as a strategy, as a systematic w a y of achieving something which is Descartes' aim: this is to discover the truth"
(p. 3 5 ) . A n d then he continues: "the strategy is to aim for
certainty by rejecting the doubtful. T o reject the doubtful here means, of course, to suspend j u d g m e n t about it, or at most to treat it as false for the purposes of the a r g u m e n t " (p. 3 6 ) . Williams is fully a w a r e , however, of Descartes's L a w of Assent: I f w e clearly and distinctly a p p r e h e n d a proposition, w e cannot refrain from believing it. H e is also a w a r e of the passages in which Descartes insists that no sane person has ever "seriously d o u b t e d " that "there really is a world, and that h u m a n beings h a v e bodies and so on." S o how does Williams fit all this together, given that, in w h a t I h a v e called the Therapy of D o u b t , w e are to doubt that there really is a world and w e are to doubt propositions that w e clearly and distinctly apprehend? Williams' solution is to distinguish between two different modes of h a v i n g propositions in mind: I f w e h a v e a proposition clearly and distinctly in mind, w e cannot suspend assent to it, whereas if w e do not h a v e that same proposition thus in mind, w e can (provided a good enough reason is offered to us). A n d this is, indeed, an authentically

Cartesian point. T h i s is w h a t W i l l i a m s says: Descartes says in the Second Replies of the things about which we can be perfectly certain, "we cannot think of them without believing them to be true," and he there claims that we cannot doubt them without thinking of them. From those premisses it follows, as he correctly points out, that we cannot doubt them. Yet it seems that there is something which counts as doubting even those propositions, so it must be possible for such a proposition to be sufficiently "before the mind" for one to entertain a doubt about it, but not be so clearly in view that one's belief in it is activated. This is not a very deep or difficult problem. All that is required is some way of referring to or indicating a proposition or idea of this kind without bringing it clearly to mind. A standard way of doing that will lie in deploying a word or sentence which expresses that idea or proposition, without, however, concentrating closely on what that word or sentence expresses. One can, granted this, entertain a doubt about an irresistible proposition, but only by not thinking about it clearly. 24
N o w , in the first place, Williams does not formulate his distinction so that it applies directly to Descartes's a r g u m e n t . Descartes, r e m e m b e r , "doubts" all propositions about a physical world w h i c h w e take to h a v e been acquired by w a y of our senses, and does so with two b r o a d questions: W h y trust that which has even once deceived one? A n d , h o w does one know that one w a s not d r e a m i n g instead of sensing? T h i s w a y of dealing with the beliefs w e acquired by w a y of w h a t w e took to be perception is scarcely "deploying a w o r d or sentence w h i c h expresses that idea or proposition, without, however, concentrating closely on w h a t that w o r d or sentence expresses." But no matter. T h e crucial issue is this: Williams interprets Descartes as saying that by the T h e r a p y of D o u b t w e bring ourselves to the
point
where w e
really don't
believe
a n y of the
things
"doubted"; a state w h i c h , for m a n y propositions, c a n only
be
achieved, he says, by not h a v i n g the doubted proposition clearly in mind. O n W i l l i a m s ' interpretation, the mind is (almost entirely) emptied of assent b y the d o u b t Descartes recommends - v a c u u m e d clean. O n m y interpretation, b y contrast, the mind remains v e r y full, since Cartesianly doubting a proposition does not consist of w i t h d r a w i n g assent from that proposition. W h a t is to be said for m y interpretation on this point and against the W i l l i a m s style of interpretation? W e l l , there is, for one thing, the 2 4

inherent implausibility of anyone's really believing that by those broad swipes that Descartes uses, one can bring oneself to the point of believing almost nothing. T h e situation does not c h a n g e if one
dwells
on those broad swipes, as Descartes says w e should (Second Set of Replies, C S M n, 9 4 ; see also First M e d i t a t i o n , C S M 1 1 , 1 5 ) . W h a t the meditating which Descartes recommends might h a v e a c h a n c e of accomplishing - so it seems to me - is that for w h i c h Descartes on m y interpretation proposed it: freeing us u p from our praejudicia
as to
w h a t w e are certain of. Secondly, and more importantly, there is Descartes's insistence that practicing his T h e r a p y of D o u b t does nothing to disturb the beliefs
presupposed
in
the conduct of our lives.
In particular,
e v e r y b o d y a l w a y s believes that he or she has a body. W i l l i a m s interprets Descartes as meaning that one can switch in and out of believing that one has a body. T h a t is not w h a t Descartes says. But thirdly, and most importantly. T h e Williams style of interpre tation renders Descartes's strategy in the Meditations
fundamentally
confused. L e t us suppose, for the sake of the a r g u m e n t , that doubting P is a l w a y s to be understood as refraining from assenting to P. Descartes offers reasons for doubting P. A n d if I h a v e a good reason for doubting P, then obviously I a m not entitled to go ahead and believe P until that reason has been answered. N o w , it turns out that even when we h a v e not excluded the possibility of the demon, there are a few propositions of which w e can be certain that if they are apprehended clearly and distinctly, they are true. Indeed, we can be certain that if they are apprehended at all, they are true. T h e s e propositions of the cogito-sort can be seen without further ado to be not only indubitable but incorrigible. B u t most of the propositions which Descartes uses in the a r g u m e n t stretching from the Second to the F o u r t h Meditation are not of that sort. A b o u t them
Descartes
instructs us, on the Williams interpretation, to doubt them, no longer to believe them. H e n c e they are not available to us for use in a n y a r g u m e n t . W i l l i a m s replies: Y e s ; but when w e apprehend
them
clearly and distinctly, w e cannot refrain from believing them. B u t this is beside the point. I f one has good reason not to assent to P but finds that in certain circumstances one cannot avoid doing so, then surely the right thing to do is to avoid those circumstances as m u c h as possible, rather than getting oneself into those circumstances and concluding that in those circumstances one is entitled to assent to P. T h e problem is an old one in Descartes interpretation. Commentators

h a v e seen that the d o u b t w h i c h Descartes urges is almost totally comprehensive in its scope; only a few beliefs of the cogito-sort
escape.
B u t they h a v e also seen that w e need to h a v e more than such beliefs left over, after w e h a v e followed the instructions to doubt, if w e are to construct the Meditations
a r g u m e n t . T h u s a dilemma: E i t h e r one
grants the radical scope of the d o u b t that Descartes urges, and finds oneself without enough entitled assentings left over to construct the argument; or one reserves enough assentings for the construction of the argument, and limits the scope of the doubt Descartes recommends. T h e W i l l i a m s style of interpretation is an attempt to escape this dilemma; it says that one can both follow the radical instructions for d o u b t and h a v e sufficient propositions left over for the argument: In following the instructions, one thinks of propositions unclearly and indistinctly but yet sufficiently to d o u b t them; in constructing the a r g u m e n t , one thinks of them clearly and distinctly. B u t that proposal just overlooks the fact that the radical d o u b t leaves one without title to use, in the a r g u m e n t , the propositions one w a s instructed to doubt. O n e doesn't receive that title until the end of the a r g u m e n t , when the reason for the radical d o u b t has been answered and the instruction lifted. O n e can only escape the d i l e m m a by distinguishing doubling P from Cartesianly enough
doubting
P. Cartesian d o u b t leaves us with more than
propositions
to construct the argument; since, for most
propositions, it never enjoins us to give up our assent to them - only to give u p our assent to the proposition that our mode of believing them is certain. But let us look at the central piece of textual evidence w h i c h W i l l i a m s offers for his interpretation. F o u n d in the Seventh Set of Replies, it goes as follows: " S o long as w e attend to a truth w h i c h w e perceive very clearly, w e cannot d o u b t it. B u t when, as often happens, w e are not attending to a n y truth in this w a y , then even though w e r e m e m b e r that w e h a v e previously perceived m a n y things very clearly, nonetheless there will be nothing w h i c h w e m a y not justly d o u b t so long as w e do not know that w h a t e v e r w e clearly perceive is true" ( C S M 1 1 , 3 0 9 ) . It m a y be noticed that this passage is not explicitly incompatible with m y interpretation. O n m y interpretation, Descartes in the first sentence is saying that when w e clearly and distinctly attend to a proposition, w e cannot refrain from believing it. I n the second he says that so long as w e do not know that the phenomenology of clarity and
2l6
Locke's
originality
distinctness guarantees truth, there is no belief-state at all about w h i c h w e cannot d o u b t that it has the highest epistemic status certitude. B u t though the passage does not explicitly contradict m y interpretation, nonetheless the point it seems to be m a k i n g is the W i l l i a m s point. Let us consider the context in w h i c h the passage occurs. In the preceding p a r a g r a p h , Descartes is making exactly the point on which I h a v e grounded m y interpretation; namely, that his "metaphysical" doubt does not c h a n g e and is not meant to c h a n g e a n y t h i n g in practical life. In the passage he expressed his a n n o y a n c e that F a t h e r Bourdin would h a v e thought otherwise: I said at the end of the First Meditation that we may doubt all those things which we have not yet perceived with sufficient clarity, since our doubt is based on "powerful and well thought-out reasons." But I said this because at that point I was dealing merely with the kind of extreme doubt which, as I frequently stressed, is metaphysical and exaggerated and in no way to be transferred to practical life. It was doubt of this type to which I was referring when I said that everything that could give rise to the slightest suspicion should be regarded as a sound reason for doubt. But my friendly and ingenuous critic here puts forward as an example of the things that I said we could doubt "for powerful reasons" the question of whether there is an earth, or whether I have a body, and so on; the effect is that the reader, if he knows nothing of my "metaphysical" doubt and refers the doubt to practical life, may think that I am not of sound mind. ( C S M 1 1 , 3 0 8 - 9 ) W h a t then follows is the passage which Williams cites, and which I quoted a b o v e . T h e passage then continues as Ibllows: From the fact that at one point I said that there was nothing that we might not doubt namely in the First Meditation, in which I was supposing that I was not attending to anything that I clearly perceived - he draws the conclusion that I am unable to know anything certain, even in the following Meditations.This is to suggest that the reasons which may from time to time give us cause to doubt something are not legitimate or sound unless they prove that the same thing must be permanently in doubt. ( C S M 11,309) In the entire passage, then, Descartes makes these three points: (1)
" M e t a p h y s i c a l " or e x a g g e r a t e d doubt is not meant to c h a n g e a n y t h i n g at all in practical life.
(2) O n e c a n emerge from metaphysical
doubt.

(3) W e m a n a g e to metaphysically doubt those propositions whose clear apprehension compels assent by recalling the fact that w e h a v e h a d the experience of clear apprehension, and then taking note of the fact that w e do not find ourselves compelled to believe that this coincides with incorrigibility. T h u s the passage as a whole is not just logically compatible with m y interpretation, but supports it: " m e t a p h y s i c a l " doubt does not alter those beliefs w h i c h are presupposed in practical life. Still, w h y does Descartes d r a w the contrast between attending "to a truth which w e perceive v e r y clearly" and remembering "that w e h a v e previously perceived
many
things
very
clearly"?
W e l l , on
my
interpretation, Cartesian (metaphysical) doubt does indeed involve a shift of focus. O n the one h a n d , there is the phenomenon of one's assent being compelled by one's clear and distinct apprehension of such a proposition as 2 + 2 = 4. O n the other hand, to e n g a g e in Cartesian doubt of that belief is to raise a question
about one's mode
of
apprehension of it, a question which requires recollection. It is to raise this question:
W a s one's
assent-compelling,
clear
and
distinct
apprehension of this proposition a guarantee of its truth? But of course one means this question generally: In general, is our assent-compelling, clear and distinct apprehension of propositions a g u a r a n t e e of their truth? T h o u g h I d o not contend that Descartes's w a y of pointing to this c h a n g e of focus is entirely lucid, it is also not entirely
infelicitous.
Cartesian doubt does involve the c h a n g e of focus to w h i c h Descartes here points: O n e remembers that one has had clear and distinct, assentcompelling apprehensions and then asks whether those are incorrigible. W h y doesn't
Descartes make the point more lucidly? I h a v e
contended that Descartes operates with a distinction between two types of doubt, and that recognizing this is fundamental to interpreting his thought. But when he tries to explain the distinction, he almost a l w a y s says that metaphysical doubt is an extreme, exaggerated, kind of doubt - that its scope is m u c h w i d e r than ordinary doubt. Y e t when someone d r a w s w h a t would seem to be the obvious implication, that in metaphysical d o u b t w e w i t h d r a w assent from all, or almost all, the things that we customarily assent to, even from the existence of a world, Descartes a l w a y s emphatically insists that that is not his meaning. It is true, of course, that w e are to Cartesianly doubt m a n y more propositions than w e are to ordinarily doubt. B u t to cite that as the difference is misleadingly off-target.
Locke's
2 18
originality
I suggest that w h a t w e witness in Descartes's writings is the struggle to get clear on w h a t exactly the project w a s to w h i c h he h a d committed
himself.
H e w a s , in
this respect,
like all
the great
philosophers. I n m y discussion I h a v e obliterated most signs of the struggle, instead offering, as it w e r e , a "rational reconstruction" of the Cartesian project. A n d then secondly, and more specifically, I suggest that at the heart of, or near the heart of, Descartes's struggle, was the struggle to get clear on the distinction between certainty as a (high) degree of truth-likelihood
and certainty as extremely firm assent.
T h e distinction w a s m a d e later in the century by the R o y a l Society g r o u p in E n g l a n d ; though even by them, not with sure-handedness. Descartes, though groping for the distinction, was even less far along the road of m a k i n g it with clarity than they were; there are passages in w h i c h one can see him shifting back and forth between the two senses. I f this speculation is correct, then pretty m u c h everything falls into place. M e t a p h y s i c a l l y doubting P is not suspending one's assent to P but w o n d e r i n g whether one's mode of believing P has the epistemic status of certainty - or more than w o n d e r i n g , h a v i n g reasons w h i c h lead one to suspend for the time being one's belief on the matter. U s u a l l y , however, one's assent to P continues throughout the process of Cartesianly doubting whether the truth-likelihood
of one's mode of
assent to P is that of certainty.

by the time w e are instructed to pair off mental states or actions with the parts of the line and w h a t they symbolize, the evaluation has become fully explicit: "take, as corresponding to the four sections, these four states of mind: intelligence

is highest; doxa, in its two forms, is lowest. F o r episteme
occurs when we are in touch with w h a t is fully real: with the realm of the necessary, eternal, i m m u t a b l e . Plato postulated the presence in us h u m a n beings of a faculty which puts us in touch with necessity: the faculty of Reason.

Happiness is to be found in quietude, ataraxia,
"an untroubled and
tranquil condition of soul," as Sextus E m p i r i c u s described i t .
25
One
feature of experience that especially perturbs people and prevents them from attaining quietude is "the contradictions in things," and doubts as to w h i c h alternative w e ought to accept (i.vi). Dogmatists, as Sextus calls them, are those w h o try to attain quietude by resolving these contradictions and settling these doubts. Skeptics regard that as futile. T h e y try instead to achieve quietude by suspension of j u d g m e n t , this being that "state of mental rest o w i n g to w h i c h w e neither deny nor affirm a n y thing" (i.iv).

appearances. " T h o s e w h o say that 'the Sceptics abolish appearances,' or phenomena, seem to me," says Sextus, "to be u n a c q u a i n t e d with the statements of our School. F o r , as w e said a b o v e , w e do not overthrow the affective sense-impressions w h i c h induce our assent involuntarily; and these impressions are 'the a p p e a r a n c e s ' " (i.x). " N o one, I suppose, disputes that the underlying object has this or that a p p e a r a n c e ; the point in dispute is whether the object is in reality such as it appears to be" (i.xi). Beliefs about how things a p p e a r to us are ineliminable,
but also certain; quietude is not threatened b y
them. But for every proposition that comes one's w a y concerning w h a t lies beyond a p p e a r a n c e , the goal is to neither believe nor disbelieve: suspend judgment. Plato has been turned on his head. I f there is a n y t h i n g stable and certain in our mental life, it is our knowledge of h o w things a p p e a r to be, says the skeptic. W h a t is important, however, if w e wish to attain quietude, is not to dwell on w h a t w e are certain of but to regulate all the rest of our mental life - Platonic pistis, dianoia, and episteme are all lumped
together
as uncertain. T o regulate it with the goal
of
eliminating falsehood from our beliefs would be, however, to suffer anxiety, unease, lack of quietude. T h e elimination
of belief, and
disbelief, is the goal. T h e ancient skeptic proposed governing assent with the goal of eliminating assent to all propositions but those recording a p p e a r a n c e . It w a s the Platonic-Aristotelian option w h i c h a b o v e all shaped the Christian M i d d l e A g e s , sometimes in Stoicized form.

and this A q u i n a s never doubts - such opinions "cannot be
totally false but must be at least partly true" (p. 1 0 8 ) . A q u i n a s speaks of the opinions of the wise as probable.
S o in answer
to our question, " T o which opinions should w e attend?" he would be willing to say, " A t t e n d to those which are p r o b a b l e . " But w h a t does he mean in calling such opinions " p r o b a b l e " ? A s B y r n e describes A q u i n a s ' thought and speech, saying of some proposition .that it is " p r o b a b l e " "refers to the authority of those w h o accept the given opinion; and from this point of view 'probability' suggests
approbation
with regard to the proposition accepted and probity with regard to the authorities w h o accept it" (p. 1 8 8 ) . I
think
there is another,
inherently
more
plausible, w a y
of
construing the T h o m i s t i c texts 011 this matter. B y r n e takes the meaning of " p r o b a b l e " in A q u i n a s to be: opinion held by persons of probity. G i v e n this understanding of " p r o b a b l e , " one then justifies attending to such opinions by a d d i n g the premise that such opinions "cannot be totally false but must be at least partly t r u e . "
27
Perhaps, though, the
core meaning of the w o r d " p r o b a b l e " for A q u i n a s (strictly, of its L a t i n counterpart probabilis),
w a s likely to be true at least in part. I f so,
then it did not belong to the meaning of the w o r d " p r o b a b l e , " but was instead a substantive thesis of A q u i n a s , that the opinions of "persons of probity" are likely to be at least partly true. O n e a d v a n t a g e of interpreting A q u i n a s ' usage in this latter w a y is that it preserves his contrast between w h a t is probable
for a person and w h a t is certain, a
contrast blurred by Byrne's construal. 2 1

N o large issues h a n g on this disagreement over the meaning for A q u i n a s of "probable"; the substance of A q u i n a s ' thought can be expressed either w a y . L e t me, though, use m y o w n interpretation rather than Byrne's. O n this interpretation, w h a t has c h a n g e d when w e get to L o c k e is not the meaning of "probable"; both A q u i n a s and L o c k e think of the p r o b a b l e as that w h i c h is likely to be true, or likely to be true at least in part. W h a t has c h a n g e d is the criterion that w e are to use for determining w h a t is probable. A q u i n a s w a s of the view that w e are to go to the best opinions of the best persons; L o c k e , to the evidence of "the things themselves." But the opinions even of the wise are normally only in part true: witness the fact that even such opinions conflict. A p p e a l i n g to the opinions of the wise does not deliver us from the conflict of opinions because, in general, such an appeal does not reveal to us which parts of their opinions are true. S o , h a v i n g begun with probable opinions collected from the wise persons in our intellectual inheritance, w h a t do w e do next? W e e n g a g e in dialectical

in argumentation - which is, be it " O n e must go deeper than mere
authority. T h e means of going deeper is dialectic" (Byrne, p. 1 4 0 ) . T h e goal of dialectic is to discover, without leaving the realm of opinion, what there is of truth in the various opinions of the wise. O n e does so by trying to discern w h a t is to be said in favor of each of the conflicting opinions. Likewise one d r a w s out the consequences of each opinion and tries to discern w h a t is to be said against it in the light of these consequences. A n d through it all one makes distinctions. T h e goal is to arrive at a sort of synthesis in which one incorporates w h a t e v e r there w a s of truth in the conflicting opinions with w h i c h one w a s dealing.
Dialectical disputation . . . takes as its very point of departure the question that is raised by opposite opinions. Each of the opposed opinions consti tutes one side of the dispute, and the disputation itself consists in the presentation and consideration of the arguments in favor of either side. The arguments thus presented in favor of one side or the other are "probable" . . . that is, probable inasmuch as they draw their conclusions from premisses which are probable. T h e propositions which serve as premisses are, in their turn, probable on the basis of widespread acceptance, or acceptance by some particular authority (whether an individual or a group), or, especially, acceptance by the opposition. In a certain sense, then, the whole purpose of the disputation is to build up the authoritative
224
Locke's
originality
probability of one side or the other - or, what is even more desirable, of both sides. Indeed, this very concern for the strength of opposite claims is, as it were, the essence of dialectical disputation. For, the purpose of disputation as such is not the determination of truth; this is the function of demonstration, which, if possible, follows upon the preparatory consideration of dialectic. T h e purpose of disputation is rather to present as well as humanly possible the reasons for adhering to either of the two opposite opinions. For . . . it is presupposed that no opinion can be totally devoid of truth, especially if it is in some way probable . . . Thus, disputational procedure implies a kind of dialectic even in the Hegelian sense. For, it is out of the very opposition of the opposing views that a new and more adequate statement of the truth - a synthesis, if you will - is sought. And from this point of view each particular opinion is but a stage in the growth of men's knowledge - not taken by itself but precisely insofar as it is opposed to another opinion. T o this extent, dialectical disputation implies intolerance of differing opinions. For, this very difference of opinion is itself an indication that there is a higher truth to be attained which will incorporate the relative merits of these lesser, more partial statements of truth. (Byrne, pp. 1 4 1 - 2 , 1 6 6 )
A q u i n a s saw clearly that dialectical reasoning remains within the sphere of opinion. T h e d r a w i n g of deductive inferences from opinion yields opinion. Y e t , sometimes e n g a g i n g in dialectical reasoning puts us within sight of something else; namely, the possibility of demonstration. T h i s is the true goal of dialectical reasoning, in the sense that this is w h a t one a l w a y s hopes for - to see h o w to get beyond the opinions of h u m a n beings to the nature of things. B y "demonstration one transcends the opinionative, the merely probable, and attains a certitude founded upon the necessary, that is, upon w h a t cannot be other than it is" (Byrne, p. 1 8 6 ) . Conversely, it w a s A q u i n a s ' view that "in this vale of tears," w h e r e "truth m a y be determined only by w a y of demonstration . . . one can arrive at demonstration only by w a y of the preparatory clash of opposing opinions" (pp. 1 6 5 6 ) . T h e contrast with Descartes and L o c k e could not be sharper. W h a t most impressed Descartes and L o c k e about the opinions of their fellow h u m a n beings was not that those of the wise contain a great deal of truth, but that, in general, they are riddled with error, with the consequence that our being reared in such a "climate of opinion" plants in us all sorts of harmful praejudicia.

T h e full originality of Locke's vision c a n now be spied. In L o c k e there is almost no echo of the long contemplative tradition. T r u e knowledge, and hence true scientia, comes to v e r y little. A n d in a n y case, w h a t is k n o w n is not some realm of higher reality. It is simply the mind and its modifications. L o c k e w a s no more concerned than were the ancient skeptics to rise a b o v e doxa. Doxa is satisfactory for our life in the world; it is our G o d - g i v e n lot. B u t w e must regulate doxa. N o t 2 8
Contrast what Descartes says in his letter of August 1 6 3 8 to Hogclande: "I do not mean that one should neglect other people's discoveries when one encounters useful ones; but I do not think one should spend the greater part of one's time in collecting them. If a man were capable of finding the foundations of the sciences, he would be wrong to waste his life in finding scraps of knowledge hidden in the corners of libraries; and if he was no good for anything else but that, he would not be capable of choosing and ordering what he found" (in K e n n y , Descartes: Philosophical letters, p. 60).
2 9
In my discussion of A q u i n a s , as indeed in my discussion of Descartes, I have sharply distinguished the practice of scientia from the preliminary exercises that must be undertaken if we arc to engage successfully in that practice. Alasdair M a c l n t y r c , in the discussion of A q u i n a s in his recent work Whose Justice? Which Rationality? (Notre D a m e , University of Notre D a m e Press, 1 9 8 8 ) , obliterates the distinction. His own evident resistance to thinking of Reason as a faculty which yields insight, plus his equally evident admiration for A q u i n a s , lead him to see in A q u i n a s only dialectic, not scientia. M a c l n t y r c imagines someone objecting to his account in the following words: Surely "rational justification, according to both Aristotle and A q u i n a s , is a matter of deducibility from first principles, in the case of derived assertions, and of the self-evidentness as necessary truths of these same first principles. S o that your account of the rational justification of Aquinas' overall view is quite inconsistent with A q u i n a s ' own account of rational justification" (pp. 1 7 2 - 3 ) . M a c l n t y r e ' s answer to the objection goes as follows: "Rational justification within a perfected science is indeed a matter of demonstrating how derivative truths (bllow from the first truths of that particular science, in some types of case supplemented by additional premises; and the justification of the principles of a subordinate science by some higher-order enquiry will be similarly demonstrative. First principles themselves will be dialectically justifiable; their evidentness consists in their recognizability, in the light of such dialectic, as concerning w h a t is the case per se, w h a t attributes, for example, belong to the essential nature of what constitutes the fundamental subject matter of the science in question" (p. 1 7 3 ) . But this is to confuse scientia itself with the dialectical preparation for engaging in scientia. W h a t gives a first principle of a science its status of being certain for someone is simply that the person "sees" it to be true. T h e r e is no getting around Aquinas' repetitive references to insight. T h e fact that a principle is certain for someone, that someone "sees" it to be true, does not imply that it will hold up in every dialectical dispute; it implies only that if it does not hold up in some such argument, someone in the argument has somewhere made a mistake. N o r , conversely, does the fact that some thesis holds up in all dialectical arguments imply that it is certain for anyone. Scientia for A q u i n a s is not what survives the dialectical sifting of tradition but w h a t transcends all such sifting. A q u i n a s is no Hegelian born out of season. Byrne's summary, though flamboyant, is accurate: " T h o m a s suffers incurably from an epistemic nostalgia for the beatific vision, wherein man's cognitiona) limitations will be filled up with the plenitude of divine omniscience. A n y knowledge short of this, however solid in itself, is by comparison but a feeble preparation for the perfection that lies beyond. For, it is then that the opiniative, the probable, the conjectural, even that which is believed on faith, will give w a y to certain and total vision" (Probability and Opinion, p. 2 3 9 ) .

regulate it with the skeptic's goal of eliminating doxa so as to attain quietude; regulate it rather with the goal of eliminating falsehood. T h e w a y to do this is not to a p p r o p r i a t e our intellectual tradition in dialectical fashion. T r a d i t i o n , after all, is filled with error, since h u m a n beings h a v e for the most part not conducted their understand ings aright. W h e n some matter of high "concernment" is before us, opinion is to be regulated b y collecting satisfactory evidence for the proposition in question; and then believing it on the evidence and with a firmness proportioned to w h a t R e a s o n tells us is the probability of the proposition on that evidence. T h i s view, shared by Locke's R o y a l Society cohorts, but first given its articulate formulation by him, w a s historically novel, and extraordinarily persuasive. It b e c a m e a prominent component in the mentality of Western modernity. O f course, as I h a v e repeatedly emphasized, there were also continuities. L o c k e continued to hold that w e h u m a n beings h a v e direct insight into some of the facts of reality, R e a s o n being one of the faculties yielding such insight. This conviction w a s fundamental to his vision. O u r opinions are to be grounded on and governed by insight. The lure of certitude has not ceased to beckon. A n d secondly, L o c k e continued
the long eudaemonistic tradition; our goal as h u m a n
beings is happiness. T h e ultimate reason for pursuing truth and seeking to avoid error is happiness. R e g u l a t e d opinion will yield i m p r o v e m e n t in our living conditions, especially when it takes the form of the new natural philosophy; and it will acquaint us with the w a y s of obedience to G o d . S u c h obedience yields happiness. O n e does not, indeed, find L o c k e joining the ancient H e b r e w songwriters in praise of the inherent delight of obeying the T o r a h of J a h w e h . R a t h e r , G o d has instituted G o d ' s law for our c o m m u n a l happiness in this life, and will reward our obedience to that law with happiness in the next, no matter w h a t it m a y be that w e with our o w n particular c h a r a c t e r find happiness in: even if " w e suppose [ h u m a n ] relishes as different there as they are here, yet the m a n n a in heaven will suit every one's palate" ( u , x x i , 6 5 ) . T h e road to true happiness is the road w h i c h leads to a society whose members obey the law of G o d as they singly enjoy political liberty and jointly struggle to master nature. R e g u l a t e d opinion is indispensable to such happiness.
CHAPTER 4
Locke and the making of modern philosophy
L o c k e intended his epistemology as a solution to the crisis of the fracturing of the moral and religious tradition of E u r o p e at the beginnings of modernity. T h a t w a s not his only intent; but it w a s prominent. F u r t h e r m o r e , L o c k e , so I h a v e suggested, w a s the first of those w h o m w e now n u m b e r a m o n g the great philosophers of early modernity to address himself to this crisis, certainly the first to offer the sort of proposal that he did. H e described a new doxastic practice; and he argued that w e are all obligated to a p p l y this practice in all cases of m a x i m a l concernment - in particular, to matters of religion and morality. O n its negative side, the practice represents the radical rejection of unverified tradition. O n its positive side, the practice resembles
the
method
which
Descartes
and
his
high
medieval
forebears had recommended for the practice of scientia - with this important revision, that probabilistic inferences be allowed in addition to deductive. T h e s e conclusions, along with others which h a v e turned u p in the course of our discussion, invite a telling of the story of early modern philosophy quite different from that w h i c h has become traditional. I propose in this last chapter to point out where and w h y the main traditional story must be discarded, to indicate some of the outlines of an alternative, more accurate story, and to show how L o c k e fits into this alternative story. M y story will remain radically incomplete, however; and that in two w a y s . I shall speak only about Descartes, L o c k e , and H u m e ; I shall say nothing at all about the place of such other undeniably great and influential early modern philosophers as B a c o n , M a l e b r a n c h e , Spinoza, Leibniz, Hobbes, and Berkeley. A n d my story will concentrate only on the epistemological aspect of early modern philosophy. In that respect it wears a regrettably conventional a p p e a r a n c e . " R e g r e t tably," I say; for m y o w n conviction is that ethical and social-political 227
John
228
Locke and the ethics of
belief
reflections occupied a far more prominent place in early modern philosophy than the traditional account acknowledges. Locke's place in m y story is prominent; but I shall not claim that L o c k e should be regarded as the father of early modern philosophy, or that he w a s the first truly modern philosopher, or that he w a s the first great modern philosopher, or a n y t h i n g else of the sort. I regard all such single-parent claims as misguided, for reasons that will become clear shortly. T h e full story of early modern philosophy requires the w e a v i n g together of a n u m b e r of distinct story lines. T h e most familiar story about the development w e now call "early modern philosophy" is the rationalist/empiricist/synthesist
story.
S o m e time before that story emerged, T h o m a s R e i d told a story about his predecessors under the rubric of " T h e W a y of I d e a s . " I shall not address myself directly to either of those stories; instead I shall address myself to Hegel's story, and to a certain v a r i a n t thereon. F o r not only has
Hegel's
story
proved
enormously
influential;
the
familiar
rationalist/empiricist/synthesist story should p r o b a b l y be seen as a (somewhat superficial) facet of Hegel's story. Hegel asked w h a t no one before him had asked: W h a t makes recent philosophy modern, rather than merely recent? O f course, the M i d d l e A g e s had already used the contrast between via moderna anliqua,
and via
a p p l y i n g it to music and philosophy, for example. B u t Hegel
had something different in mind. T h e society of recent times, Hegel believed,
w a s in its foundations
different from the society
that
preceded it. Its Spirit, its Geisl, was different. Between the society of recent times and that w h i c h preceded it - not ancient, of course, but medieval
there was a fundamental breach, m a k i n g present society not
just present but modern. T h e culture of this new society both expressed w h a t was new in this society and contributed to its formation. A n d philosophy is part of this new, distinctly modern, culture. H e n c e , modern philosophy. " T h e principle of the modern world is freedom of subjectivity," says Hegel, "the principle that all the essential factors present in the intellectual whole are now coming into their right in the course of their development."

"In this principle all externality or authority is

[truth] that freedom - the peculiar possession of spirit - is acknowledged, that spirit is i n w a r d l y at home with itself [in sich bei sich ist] and has 2
this consciousness within it." J t i r g e n H a b e r m a s , in his discussion of Hegel's concept of modernity, suggests that "the term 'subjectivity' carried primarily four connotations [for H e g e l ] : (a) individualism:
in
the modern world, singularity particularized without limit can m a k e good its pretensions;
(b) the right to criticism:
the principle of the
modern world requires that w h a t a n y o n e is to recognize shall reveal itself to him as something entitled to recognition; (c) autonomy of action: our responsibility for w h a t w e do is a characteristic of modern times; (d) finally, idealistic philosophy
itself: Hegel considers it the work of
modern times that philosophy grasps the self-conscious (or self-knowing) Idea."
3
A s to origins: It was Hegel's conviction that this principle of subjectivity, w h i c h constitutes
"the greatness of our time," w a s
introduced into history by the Protestant Reformation: W e have already remarked upon the first manifestations of this principle, the principle of our own h u m a n thought, our own knowing, its activity, its right, its trust in itself. It is the principle of finding satisfaction in our own activity, reason, imagination, and so forth, of taking pleasure in our products and our work and deeming it permissible and justifiable to do so, indeed, regarding our own work as something in which we m a y and should essentially invest our interest. . . This validation of the subjective d o m a i n now needed a higher - indeed, the highest - confirmation in order to be completely legitimated and to become even the absolute duty. T o attain to this level it had to be grasped in its purest shape. T h e highest confirmation of this principle is the religious confirmation, when this principle of our own spirituality and our o w n autonomy is recognized in our relation with G o d and to G o d . . . 2

This, then, is the great principle of [the R e f o r m a t i o n ] , that all externality disappears at the point of the absolute relationship to G o d . All selfestrangement, with its consequent dependence and servitude . . . disappears. This principle of subjectivity became a moment of religion itself and thereby attained to its absolute recognition . . . T h e principle of the Reformation . . . was the moment of spirit's being-withinself, of its being free, its coming to itself. T h a t is just w h a t freedom means: to relate oneself to oneself, in the determinate content. 4
T h i s interpretation of the Reformation, so it seems to me, is a tangle of insight and error. But rather than entering that beckoning side path, let me go on to observe that it follows from Hegel's interpretation o f modernity that w h a t makes philosophy
modern, as indeed w h a t
makes any cultural development modern, is that its theme is subjectivity; Hegel interprets modern culture as the culture of Protestantism. A n d though he regarded F r a n c i s B a c o n and J a c o b Boehme as important preparatory figures, "It is with Descartes that the philosophy of the modern period, o r abstract thinking, properly begins."
5
Now we come lor the first time to what is properly the philosophy of the modern world . . . Here, we may say, we are at home and, like the sailor after a long voyage, we can at last shout " L a n d h o . " Descartes made a fresh start in every respect. T h e thinking or philosophizing, the thought and the formation of reason in modern times, begins with him. T h e principle in this new era is thinking, the thinking that proceeds from itself. W e have exhibited this inwardness above all with respect to Christianity; it is preeminently the Protestant principle. T h e universal principle now is to hold fast to inwardness as such, to set dead externality and sheer authority aside and to look upon it as something not to be allowed. In accordance with this principle of inwardness it is now thinking, thinking on its own account, that is the purest pinnacle of this inwardness, the inmost core of inwardness - thinking is what now establishes itself on its own account. This period begins with Descartes. What is deemed valid or what has to be acknowledged is thinking freely on its own account, and this can happen only through my thinking freely within myself; only iti this w a y can it be authenticated for me. This means equally that this thinking is a universal occupation or principle for the world in general and for individuals. H u m a n beings must acknowledge and scrutinize in their own thoughts whatever is said to be normative, whatever in the world is said to be authoritative; what is to rank as established must h a v e authenticated itself by means of thought. 6

freedom of subjectivity. T h e preceding discussion then compels the conclusion that, whereas L o c k e was certainly a modern philosopher, Descartes was not yet one. F o r Descartes understood the project to which he devoted his endeavors, the project of scientia, as a project for the intellectual elite, not as "a universal occupation or principle for the world in general
and
for individuals." It w a s L o c k e ,
not
Descartes, w h o insisted that all h u m a n beings whatsoever, provided just that they be sane adults, "must a c k n o w l e d g e and scrutinize in their own thoughts w h a t e v e r is said to be normative, w h a t e v e r in the world is said to be authoritative." It was L o c k e w h o insisted that, with
respect
to
anything
of m a x i m a l
concernment
to
anyone
whatsoever, " w h a t is to rank as established must h a v e authenticated itself by means of thought." It will be said that this is going by the letter of Hegel's analysis rather than the spirit. L e t it be conceded that Hegel was mistaken in attributing to Descartes the sort of universaJism that he does
-
because, let it be conceded, Hegel failed to discern that Descartes's lifelong project was to renew and practice scientia. Nonetheless, there is a momentous
difference between
Cartesian w a y of carrying
the medieval
out this c o m m o n
w a y and
the
project: W h e r e a s the
medievals regarded a dialectical appropriation of the textual tradition as the best preparation for the practice of scientia, Descartes argued that the best preparation requires closing one's books and engaging instead in the Therapy of D o u b t . In this difference, there is point to Hegel's comments. T h e r e is indeed this difference between Descartes and the medievals; the difference is important, and was seen as important by Descartes's contemporaries and successors. Descartes's closing of the books is something distinctly modern. Nonetheless, it is worth noting that in Descartes's reason for rejecting the dialectical appropriation of the textual tradition as preparation for the practice of scientia, there was nothing specific to modernity. T o practice scientia, one has to be able to discriminate between those propositions which are immediately certain for one and those w h i c h are not. W h a t impressed Descartes was that experience and reading fill us with mistaken praejudicia
as to
w h a t w e are certain of; and that even when we do reflect on the matter, w e pull back from the consideration of the truly radical possibilities. A c c o r d i n g l y , before doing anything else w e must liberate ourselves from these praejudicia
and these hesitations; Descartes w a s
persuaded that the best w a y to do so was to engage in his T h e r a p y of
2
3

D o u b t , and to do so in truly radical fashion. I submit that, in principle, a medieval philosopher could h a v e said exactly the same thing. N o "principle of subjectivity" w a s coming to expression in this reason. Neither w a s there a n y a c k n o w l e d g m e n t of the development I h a v e emphasized: the fracturing of the moral and religious tradition and the emergence of raging conflicts over biblical interpretation. T h e issue is simply this: W h e n reading texts which are not specimens of scientia, one is likely to a c q u i r e mistaken praejudicia
which inhibit
one's ability to discriminate the certain from the uncertain. Does that d a n g e r outweigh
the likely benefit of h a v i n g one's
imagination
stimulated into discerning new w a y s of a d v a n c i n g scientia? Descartes emphatically thought that it did. T h e mcdicvals thought that it did not. Therein lies the difference. But doesn't the core of Hegel's claim still remain intact, his claim that Descartes was the first to construct a philosophy in which freedom of subjectivity is central? T h e r e is room for doubt. O b v i o u s l y subjectivity occupies an important place in the overall a r g u m e n t and pattern of" thought of the Meditations;
and contrary to those w h o

it seems to me that Descartes believed all of it, and saw the arguments developed there as constituting an important link in his comprehensive project. Nonetheless, the suggestion that subjectivity was the organizing center of Descartes's philosophy goes much too far; in Descartes's work as a whole it occupies only a subsidiary, albeit important, place. Descartes's project, to say it once again, was the renewal and expansive practice of scientia, not the development of a philosophy of subjectivity. A n d as to content of his execution of that project, it was especially "first philosophy" and "natural philosophy" which occupied his attention. His largest and most mature book was Principles Philosophy.
T h e Meditations,
of
which are, of course, the locus classicus for
the Hegelian interpretation, were presented as meditations on first philosophy,
that is, on metaphysics - though in fact they are more than
that. It is w e w h o find Descartes's S e c o n d M e d i t a t i o n the most important, fascinating, and suggestive thing he ever wrote. T h e r e is no evidence that Descartes regarded it thus. O n l y when w e come to L o c k e does the self o c c u p y center stage. Locke

modern, L o c k e proves to be the first great modern philosopher, not Descartes
though w h a t pushed the principle of freedom of subjectivity
to center stage in Locke's thought was not his Protestantism but his unwillingness simply to appeal to the texts, even the biblical texts, when at a standstill in answering questions about morality and revealed religion. In Charles T a y l o r ' s book on Hegel, titled simply Hegel, and in his later book, The Sources of the Self, one finds an interpretation of early modern philosophy w h i c h is both a variation on, and an elaboration of, Hegel's account: a variation, in that T a y l o r offers a different account of the origins of the centrality of subjectivity in modern philosophy, an elaboration, in that T a y l o r articulates in his o w n w a y 7
Hegel's notion oi freedom of subjectivity. T h o u g h it is the elaboration I mainly w a n t to consider, w e must begin with a w o r d about T a y l o r ' s alternative view as to origins. R a t h e r than adopting Hegel's thesis that the main source of modernity was the religious legitimation by Protestantism of freedom of subjectivity, T a y l o r adopts M a x W e b e r ' s alternative account of the origin of modernity - or at least, one important strand of that account. It w a s W e b e r ' s conviction that the essence of modernization is to be located
in two related
phenomena.
First, in
the emergence
of
differentiated spheres; specifically, in the emergence of the differentiated social spheres of economy and state, along with household, and in the emergence of the differentiated cultural spheres of science, art, and law and ethics. Secondly, in the spread of rationalized thought and action within these spheres. T h e fundamental d y n a m i c of our modern, capitalist economies is rationalization, W e b e r thought, just as the fundamental d y n a m i c of our modern, bureaucratic states is rational ization; so too, rationalization is w h a t accounts for the fundamental character of modern science, oriented as it is t o w a r d prediction, grounded as it is in sensory experience, intertwined as it is with technology. N o t only does the d y n a m i c of rationalization account for w h a t takes place within these differentiated social and cultural spheres; it accounts as well, W e b e r thought, for their emergence. His a r g u m e n t comes in three parts, only two of w h i c h are explicitly developed in his published work, and only the first of w h i c h is mentioned directly by Taylor. 7

Locke and the ethics of
belief
W e b e r regarded it as characteristic of "primitive" religions for the participants in those religions to think of the world as filled with magical and sacred powers — to think of the world as enchanted. A condition of the emergence of modern society and culture is the disappearance of such a view; modernity presupposes the disenchant ment, the Enlzauberung
(literally, de-magicalizing) of the w o r l d . T h e
world for a modern person is an inherently meaningless, indifferent terrain for action. T h e displacement of "primitive" religions by the world religions was the first large step along the road to this disenchantment; that step, by now far back in the mists of history, already represented the d y n a m i c of rationalization at work. F o r religions are attempts to find meaning in h u m a n existence; but the meanings proposed by the "primitive" religions a l w a y s found themselves without a satisfyingly "rational" account of suffering and injustice. T h e emergence of the world religions by no means represented the completion of disenchantment, however; the process continues to work
itself out
within
these religions,
the
d y n a m i c still
being
rationalization as the response to questions of theodicy. T h o u g h W e b e r apparently believed
that the d y n a m i c of
rationalization
operating within each world religion, as a sort of "internal logic," would eventually lead each of them to a d o p t a fully disenchanted view of the world, he clearly regarded the d y n a m i c as operating most powerfully in religions exhibiting that particular configuration of attitudes and convictions which one finds in J u d a i s m , Christianity, and
(presumably) Islam.
World
religions can be distinguished
along three
dimensions.
S o m e , the theocentric, sharply separate the divine from the world; others, the cosmocentric, locate the divine within the world. S o m e , the world-affirming, see the world as basically good; others, the world-rejecting, see the world as basically bad. A n d some proclaim the active, "ascetic" life as the road to salvation, whereas others proclaim the contemplative, "mystical" life as being that. W e b e r speculated that the pressures of rationalization toward a disenchanted view of the world would be felt most powerfully in religions w h i c h are theocentric, world-rejecting, and ascetic; he interpreted J u d a i s m and Christianity as exactly such religions. In J u d a i s m and Christianity there w a s , he thought, a powerful critique of actions performed simply out of habit or affect, and a powerful pressure toward the formation of a generalized ethic of principle - the corollary of w h i c h ,
Locke and the making of modern
philosophy
235
he thought, is that the world itself is viewed as devoid of meaning, spread before the agent simply as the objective terrain in and on w h i c h action obedient to G o d is to be performed. W e b e r regarded the lifestyle of the monks as the finest e x a m p l e in medieval times of this religious type; they were the virtuosi of the d a y . T h e i r lifestyle w a s the most methodical, that is, the most
rationalized.
A disenchanted view of the world is no more, however, than a necessary condition of the emergence of modernity. A n d w h a t especially intrigued W e b e r w a s this question: H o w could our capitalist economy, with its inherently "unbrotherly" modes of operation, h a v e emerged from the cradle of a religion whose ethic, though coupled with an increasingly disenchanted view of the world, w a s nonetheless an ethic of "brotherliness"? W h a t convictions were available for legitimating capitalist entrepreneurialism? W e all know W e b e r ' s answer: It w a s the English Puritans in particular, and the Calvinists in general, w h o first exhibited formation
the fully methodical, fully rationalized character-
of "inner-worldly
asceticism"
requisite
for
capitalist
entrepreneurship; and they legitimated their actions by extruding the ethic of brotherliness from the economic sphere and putting in its place "the Protestant ethic," as W e b e r called it, a c c o r d i n g to w h i c h the believer's capitalist entrepreneurship is legitimated by its being the calling (vocalio) given him by G o d , with success therein being a sign of his belonging to the c o m p a n y of G o d ' s elect.
8
T h e r e remains a crucial part of W e b e r ' s a r g u m e n t which was never fleshed out by him. T o act and think as w e do within our rationalized social and cultural spheres requires that w e view and treat the world as disenchanted; W e b e r offered an account of how that c a m e about. T o act and think as w e do in our capitalist economy requires that one 8
I disagree at this point with the otherwise superb reconstruction of Weber's thought b y j i i r g e n Habermas in The 7 heory of Communicative Action: Vol. I, Reason and the Rationalization of Society, tr. T . M c C a r t h y (Boston, Beacon Press, 1 9 8 4 ) , pp. 1 4 3 - 2 7 1 . H a b e r m a s interprets W e b e r as holding that the Puritans embodied the rationalized ethic of conviction belonging to the Christian worldview in their economic activity, thus transposing rationalization from the cultural into the social sphere. Weber's thought was decisively different. The rationalized ethic of conviction which is properly part of the Christian worldview is an ethic of "brotherliness." W h a t operates in the economic sphere is something quite other than "brotherliness." Hence the tensions between the two which W e b e r so emphatically emphasizes in his famous chapter "Religious Rejections of the World and their Directions." This interpretation confronted W e b e r with his famous puzzle: W h y would Christians ever have regarded such "unbrotherly" action as legitimate? His solution was to attribute to the Puritans, presumably in addition to their convictional ethic of "brotherliness," that very different ethic, if "ethic" it can properly be called, which he calls "the Protestant ethic," according to which G o d wants the elect to practice their "vocations" according to the laws of the relevant social sphere, whether or not such action is "brotherly."

the differentiation of these spheres? T o that question, W e b e r g a v e no answer. W e know enough about his style of thought, however, to know that if he had given an answer, the d y n a m i c of rationalization would h a v e figured prominently therein! T a y l o r accepts at least the disenchantment component in W e b e r ' s picture of the origins of modernity. R a t h e r than focusing on the modern economy, however, as W e b e r does, he focuses on the new science.
A n d rather than
emphasizing
the
tension a m o n g
the
differentiated spheres and the absence of m e a n i n g from all of them, as W e b e r does, he emphasizes that modern science depicts for us "a vision of things as devoid of intrinsic meaning, of the world as the locus of contingent correlations to be traced by observation, conforming to no a priori pattern." " I h a v e spoken of this vision of the world as 'disenchanted' using W e b e r ' s term," he says. H e goes on to suggest an alternative w o r d , the w o r d "objectified," "to cover this denial to the world of inherent meaning . . . T h e point of using this term is to mark the fact that for the modern view categories of meaning and purpose apply exclusively to the thought and actions of s u b j e c t s . "
10
T a y l o r goes beyond W e b e r in suggesting that an essential corollary to this modern picture of an objectified world is a new notion of the self as a self-defining
subject; "a disenchanted world is correlative to a
" T h e r e is one passage in Weber's chapter on "Religious Rejections of the World and their Directions" which contains a revealing hint, however: "an especially important fraction of all cases of prophetic and redemptory religions have lived not only in an acute but in a permanent state of tension in relation to the world and its o r d e r s . . . The more the religions have been true religions of salvation, the greater has this tension been . . . T h e tension has also been the greater, the more rational in principle the ethic has been, and the more il has been oriented lo inward sacred values as means of salvation . . . Indeed, the further the rationalization and sublimation of the external and internal possession o f - in the widest sense -- 'things worldly' has progressed, the stronger has the tension on the part of religion become, f o r the rationalization and the conscious sublimation of man's relations to the various spheres of values, externa] and internal, as well as religious and secular, have then pressed towards making conscious the internal and lawful autonomy of the individual spheres; thereby letting them drift into those tensions which remain hidden to the originally naive relation with the external world." H . H . Gcrth and C . W . Mills (eds. and trs.), From Max Weber: Essays in Sociology ( N e w Y o r k , Oxford University Press, 1 9 5 8 ) , p. 3 2 8 . The picture which comes through is the neo-Kantian picture, according to which there just are those "individual spheres" in the nature of things, with their "internal and lawful aulonomy," rationalization being the d y n a m i c which reveals those spheres and sets thought and action within them free from external domination, so that life within each can develop according to the "internal logic" of that sphere. 1 0

N o w the shift that occurs in the seventeenth-century revolution is, inter alia, a shift to the modern notion of the self [as a self-defining s u b j e c t ] . " T a y l o r goes on to suggest "that one of the powerful attractions of this austere vision [of the world not as a locus of meaning, but rather of contingent, de facto correlations], long before it 'paid off' in technology . . . lies in the fact that the winning through to a self-defining identity w a s a c c o m p a n i e d by a sense of exhilaration and p o w e r , that the subject need no longer define his perfection or vice, his equilibrium or disharmony, in relation to an external order. W i t h the forging of this modern subjectivity there comes a new notion of freedom, and a newly central role attributed to freedom, which seems to h a v e proved itself definitive and irrevers ible."

underlies
in the c h a p t e r "Locke's Punctual Self" from his
recent book The Sources of the Self, he elaborates w h a t he sees as Locke's contribution to the emergence of this modern notion of the self as self-defining subject, along the w a y explaining in more detail w h a t he has in mind by "self-defining." L e t me first state the core of his interpretation, using his o w n terminology; and then explain in more detail some of its parts, and offer m y critique. L o c k e , says T a y l o r , urged that w e h u m a n beings "objectify" and "disengage" ourselves from the actualities of self and world to such an extent as to take up w h a t m a y be described as the stance of a " p u n c t u a l " self. H e urged this both in the domain of action and in the domain of knowledge and belief, the point of the exercise being to gain mastery over one's self. Pervasive in L o c k e is the theme of control. In so far as one gains such control over one's self, one liberates oneself from the "objectified" actualities of self and w o r l d . T h u s correlative to the theme of control is that of freedom.
In urging all this, L o c k e
worked, says T a y l o r , with a "procedural" understanding of rationality. A s to w h a t led L o c k e to such views, T a y l o r emphasizes two things:

T a y l o r is right to insist on the importance in L o c k e of the theme of self-mastery, and of its corollary, freedom; as he is right to insist on the importance of the theme of the self-discipline required by self-mastery and liberation.

Nevertheless, it is indubitable that governance

is a central theme in
Locke's epistemology. F o r the rest, however, T a y l o r ' s interpretation severely distorts Locke's thought,
the distortion
in great measure caused by the
all-too-characteristic, near-total neglect of Book iv of the Essay. L e t us begin
with T a y l o r ' s claim
that the tradition
before L o c k e
and
Descartes operated with a "substantive" view of rationality, whereas they operated
with
a "procedural." ( T a y l o r
adds that
almost
everyone after Descartes and Locke has followed them in adopting the procedural understanding of rationality, so that this, in his view, is one of the hallmarks of modern thought.) By the substantive view of rationality T a y l o r means the view that reason is a faculty for apprehending an objective order which includes norms for conviction and action. O n this view, the extent to which a person is rational is determined by the "substance" of his or her convictions. In so far as those convictions are out of accord (do not correspond) with the objective order, that person's reason has not been at work. T h a t person was and is not rational. A s one would surmise, Plato is T a y l o r ' s favorite e x a m p l e of someone w h o held this substantive view of rationality - though he attributes it to the ancients in general. T o see the good is to love it, Plato thought, and w h o e v e r loves it will e m b o d y it in his or her life; accordingly, not only does the substance of a person's convictions indicate to w h a t extent he or she is rational, but the substance of a person's actions do so as well. L e t me allow T a y l o r to state in his own words w h a t he has in mind by the "substantive" view of rationality:
1 4

Locke and the making of modern philosophy
239
R e a s o n is the capacity to see and understand . . . S o to be ruled by reason is to be ruled by the correct vision or understanding. T h e correct vision or understanding of ourselves is one which grasps the natural order . . . So reason can be understood as the perception of the natural or right order, and to be ruled by reason is to be ruled by a vision of this order. Plato offers what we can call a substantive conception of reason. Rationality is tied to the perception of order; and so to realize our capacity for reason is to see the order as it is. T h e correct vision is criterial. T h e r e is no w a y one could be ruled by reason and be mistaken or wrong about the order of reality. It makes no sense for Plato to imagine a perfectly rational person who would nevertheless have quite erroneous views about the order of things or the morally g o o d . ' O n c e reason is substantively defined, once a correct vision of the order is criterial to rationality, then our becoming rational ought not most perspicuously to be described as something that takes place in us, but rather better as our connecting up to the larger order in which we are placed. R e a s o n is our capacity to see being, illuminated reality. J u s t as the eye cannot exercise its function of seeing unless there is reality there and it is properly illuminated, so reason cannot realize its function until we are turned towards real being, illuminated by the G o o d . T h a t is w h y reason has to be understood substantively, and w h y the vision of the true order is criterial for rationality."' 5
W h a t , by contrast, is procedural rationality? T a y l o r ' s best description occurs in the context of his discussion of Descartes's
mechanistic
picture of the world and his b o d y / m i n d dualism. T h e s e , says T a y l o r , cannot "but result in a very different
notion of the
self-mastery
w r o u g h t by reason. This cannot mean w h a t it meant for Plato, that one's soul is ordered by the G o o d which presides over the cosmic order w h i c h one attends to and loves. F o r there is no such order . . . T h e Cartesian option is to see rationality, or the p o w e r of thought, as a capacity
we have
to construct orders which
meet
the
standards
d e m a n d e d by knowledge, or understanding, or certainty . . . I f w e follow this line, then the self-mastery of reason now must consist in this c a p a c i t y being the controlling element in our lives, and not the senses; self-mastery consists in our lives being shaped by the orders that our reasoning capacity constructs according to the appropriate standards."
17
" W h a t w e are called on to do is not to become contemplators of order, but rather to construct a picture of things following the canons of rational thinking . . . Rationality is a b o v e all a property of the process of thinking, not of the substantive content of t h o u g h t . "

If one were going to place m u c h weight on this distinction between substantive and procedural rationality, one would h a v e to clarify and 15

articulate it a good deal more than T a y l o r does. B u t even without such development I think w e can see clearly enough w h a t T a y l o r has in mind to enable us also to see that it is simply not true that L o c k e and Descartes adopted a procedural view of rationality. In the first place, the project of constructing something w h i c h one's reason tells one satisfies certain standards that one has set for oneselfthe phenomenon of one's reason telling one this seems to be w h a t T a y l o r means by " p r o c e d u r a l " rationality - w a s far from absent in the tradition. T a y l o r neglects it; but surely the traditional project of scientia w a s exactly such a project. T h e tradition by no means thought that reason had only to do with contemplation,
not at all with
construction. P r o b a b l y one should interpret Plato's remarks in Book vi of the Republic
as advice concerning how one is to attain to a vision
of the good rather than advice as to how one is to construct
scientia.
But by the time w e get to Aristotle the project of constructing scientia is clearly in view. W h a t must be added, though, is that the tradition would not be h a p p y with T a y l o r ' s sharp contrast between construction and contemplation.
By constructing scientia
one contemplates
the
order of necessity. O n the other hand, there is no hope whatsoever of understanding L o c k e unless one realizes that reason for him is as m u c h a faculty of apprehension as it was for the ancients, and that w h a t reason apprehends is by no means just that some belief or action satisfies some standard one has e m b r a c e d . Reason is that faculty w h e r e b y w e apprehend necessities in general. O v e r and over, as w e h a v e seen, L o c k e uses the word "perceive" to describe w h a t reason does. A n d he a d a m a n t l y refuses to admit that reason can go w r o n g
or even that a m o n g our
faculties there is any which can accurately mimic the phenomenology of reason. H e n c e it is as true for L o c k e as it was for Plato that failure to apprehend some item in the realm of necessity
whether or not that
failure is a c c o m p a n i e d by the beliej that one has apprehended some such item
is a failure of reason, of rationality. T h e content,
the
"substance," of one's thought is a mark of the degree of one's rationality. O f course, L o c k e was far from being a Platonist. Part of the difference lies in disagreement over the ontological status of that w h i c h reason apprehends. F o r Plato, w h a t one apprehends b y reason is mind-independent ideal. F o r L o c k e , w h a t one apprehends by reason is one's mind and its modifications, including its ideas. W i t h an eye on the ontological status of that w h i c h reason apprehends, one might say that Locke's picture of the self is that of the "claustrophobic" self.
Locke and the making of modern
philosophy
241
F u r t h e r m o r e , L o c k e h a d a different understanding of the nature of norms. C o u n t e r to T a y l o r ' s interpretation, L o c k e clearly held that norms are a m o n g w h a t reason apprehends. Locke's concept of a l a w of nature w a s that of a moral obligation apprehensible by reason. B u t L o c k e did not share Plato's conviction that the realm of necessity includes eternal, self-exemplifying virtues, and that all persons are of such a nature that for them to know these self-exemplifying virtues is to love and seek to imitate them. A s to the former point, morality is grounded in the c o m m a n d s of G o d . A s to the latter, L o c k e w a s Augustinian: O n e might by reason apprehend a law of nature without trying to obey it; between apprehension and intention comes will. T h e s e observations suggest that T a y l o r ' s substantive/procedural distinction lumps together a n u m b e r of distinct issues in such a w a y as to m a k e the disjunction
non-exhaustive.
L o c k e holds neither
a
substantive nor a procedural view of reason. Plato and L o c k e share the conviction that reason is a faculty of apprehension; they share w h a t might be called an apprehensive view of reason. T h e y disagree on w h a t it is that reason apprehends and w h a t w e are to do with its apprehensions. W h e n T a y l o r speaks of "substantive" reason, he has in mind the complex view that reason is a faculty for a p p r e h e n d i n g an objective order of necessity incorporating p a r a d i g m s for belief and action. I f w e are to understand w h a t divides L o c k e from Plato, the issue must be divided. T h e d e c a y of the conviction that we h u m a n beings have in us a faculty for apprehending necessary truths occurs after L o c k e ; from Plato to L o c k e , almost everyone in the Western philosophical tradition shared this conviction. W i t h o u t such a p p r e hension, said L o c k e , w e would be w a n d e r i n g in darkness. Locke's innovation
(shared
with
his associates
in
the R o y a l
Society) is to be located in his view as to w h a t w e are to do with reason's deliverances. H e r e too, though, w e must step carefully. Locke's innovation was not in his insistence that w e should use reason's deliverances constructively - procedurally, if you will. A l l those w h o had recommended scientia had said the same. Locke's innovation lies in what
it was he thought
guidance. Scientia,
w e should
construct under
reason's
of course; L o c k e never rejected the project of
scientia. But he went on to suggest that when w e are obligated to do our best in the g o v e r n a n c e of beliefs,
then too w e are to listen to the
voice of R e a s o n . O f course, one's listening to the voice of R e a s o n and a p p l y i n g w h a t one hears it saying, in accord with the principle of

Locke and the ethics of belief
proportionality, might result in one's believing something false - since w h a t is highly probable, and thus permissible to believe, might nonetheless be false. T h u s w h a t T a y l o r notes comes about: the "substance" (content)
of one's beliefs is not a l w a y s by itself an
indicator of the extent to w h i c h one has been rational. T h e other main part of T a y l o r ' s interpretation is the claim that L o c k e w a s more radical than a n y o n e before him in the recommended scope of objectification, disengagement, and control - that L o c k e w a s as radical as a n y o n e could possibly be. " T h e subject of disengagement and rational control," says T a y l o r , "has become a familiar modern figure
. . . T h e key to this figure is that it gains control through
disengagement. Disengagement is a l w a y s correlative of an 'objectifi cation' . . . Objectifying a given domain involves depriving it of its normative force for u s . "
19
O n Locke's view, according to T a y l o r , "we
are to wrest the control of our thinking and outlook a w a y from passion or custom or authority and assume responsibility for it ourselves. Locke's theory generates and also reflects an ideal of independence and self-responsibility, a notion of reason as free from established customs and locally d o m i n a n t a u t h o r i t y . "
20
" T h e disen
gagement both from the activities of thought and from our unreflecting desires and tastes allows us to see ourselves as objects of far-reaching reformation."
21
Indeed, so radical is Locke's proposal as to the proper
scope of objectification, disengagement, and control that only a self which is a mere "point" could act thus: " T h e subject w h o can take this kind of radical stance of disengagement to himself or herself with a view to remaking, is w h a t I w a n t to call the 'punctual' self. T o take this stance is to identify oneself with the p o w e r to objectify and remake, and by this act to distance oneself from all the particular features which are objects of potential c h a n g e . W h a t w e are essentially is none of the latter, but w h a t finds itself c a p a b l e of fixing them and working on them. T h i s is w h a t the i m a g e of the point is meant to convey."
22
Is it true that L o c k e r e c o m m e n d e d that w e each engage in so radical a critique and control of self as to assume that one is nothing but the p o w e r to engage in such radical critique and control? Certainly not. T a y l o r correctly observes that to engage in critique and control of everything about the self presupposes aligning oneself "against a n y view w h i c h sees us as naturally tending to or attuned to

the truth, whether it be of the ancient variety, that w e are q u a rational beings constitutionally disposed to recognize the rational order of things; or of the modern variety, that w e h a v e innate ideas, or an innate tendency to unfold our thought t o w a r d the t r u t h . "

It
requires that "Instead of being swept along to error b y the o r d i n a r y bent of our experience, w e stand back from it, w i t h d r a w from it, reconstrue it objectively, and then learn to d r a w defensible conclusions from i t . "
24
B u t L o c k e does not deny, in this sense, the presence of an
innate bent toward the truth in us. H e affirms in us the presence of R e a s o n . A n d never does he propose a critique of Reason; R e a s o n cannot go w r o n g . In turn, R e a s o n is for L o c k e just one of the faculties yielding insight. T h e r e is no significant difference between L o c k e and Plato on the presence in us of an innate bent t o w a r d the truth, or on w h e r e in us that bent is to be located. O r if there is a difference, L o c k e is not more radical, but less radical, than Plato. F o r Locke acknowledges insight into various contingent facts, whereas (perhaps) Plato did not. A n d as to the issue raised by T a y l o r of Locke's denial of innate ideas: L o c k e makes clear that though he denies innate ideas, he affirms innate powers.
T h e workings of our innate powers, coupled with the
i m p a c t of reality on us, account, he thought, for all our ideas. I f one wants to find in the seventeenth century a truly radical proposal for objectification, disengagement, and control, one w o u l d be well advised to look into the Calvinist movement. It w a s the Calvinists w h o insisted that w e are "fallen" in all dimensions of our existence
including our R e a s o n . W e are, in this sense, "totally
d e p r a v e d . " T h e y insisted, accordingly, that for g u i d a n c e in reform of self and world w e must look outside ourselves, to the W o r d of G o d . O f course, they did not insist that everything in all our thoughts and actions, cultural products and social constructions, is b a d . T h e y did not, in this sense, believe that "there is no health in us." R a t h e r , they held that only the W o r d of G o d provides us with a reliable criterion for sorting through w h a t is good and b a d . H e r e , then, there is a truly radical disengagement. But these same Calvinists would h a v e firmly rejected T a y l o r ' s conclusion that they were presupposing a purely punctual self. F o r they w o u l d h a v e insisted that those dimensions of one's person w h i c h one subjects to critique nevertheless belong to one's self. S o m u c h , indeed, do they belong to one's self that one confesses before G o d all that is sinful in

the self.
T h e self they presupposed w a s not a punctual self but a self naked before the eyes of G o d . T a y l o r ' s claim, that fundamental to modern philosophy is the notion of the self-defining
subject as the corollary of W e b e r ' s
disenchanted w o r l d , and that Descartes and L o c k e represent the initial development of this idea, cannot be sustained. T h e notion of the subject as self-defining comes after Descartes and after L o c k e . A n d to repeat a point m a d e earlier: N o t even is it the case that the self is central in Descartes's thought; in Locke's thought, Yes, in Descartes's, No. F u n d a m e n t a l to W e b e r ' s interpretation of modernity is taking societies as one's basic entities, and then distinguishing within a given society various spheres of that society
various social spheres, and
various cultural spheres. M y o w n preference is for w h a t has come to be called the "world-system" interpretation, according to w h i c h w e discard society as our unit of analysis and work instead with economies, states, nations, and religious groupings as our units of analysis. W h a t characterizes the social world of modernity is the emergence of economies which do not coincide with, but o v e r l a p , distinct states; indeed, that there is in general a striking lack of coincidence a m o n g economies, states, nations, and religious groupings in the modern world. A r e a s of the world displaying deep economic linkages are nonetheless under the sovereignty of different states; and within these states there are distinct nationalities and distinct religions. Conversely, members of the same nation find themselves under the sovereignty of distinct states, as do members of the same religion. Part of w h a t makes modern philosophy modern is that it deals with philosophical questions raised by this new social order. Locke's letters concerning toleration addressed questions raised by the emergence in E n g l a n d of distinct religious groupings within a single polity; his treatises concerning civil government addressed fundamental questions raised by the new e c o n o m y and the new state. F u r t h e r m o r e , the placing of the self, and in particular, of the volitional self, on the a g e n d a of modern philosophy is to be seen as a natural response to the centrality of volition in this new social order. T h e g r a d u a l loss of ascriptivism in capitalist economies means that the social roles one

Locke and the ethics of belief
the list. T h e R e f o r m a t i o n did not represent a w o r k i n g out of the logic of the situation, but a c a t a c l y s m . Locke's epistemology w a s addressed to that cataclysm. T h a t is w h a t makes it modern. T h e r e is more to modernity
than fractured moral and
religious
traditions;
other
philosophers h a v e addressed themselves to other phases of modernity. O t h e r things m a k e them modern. B u t this - along with his treatment of religious toleration and of civil authority - is w h a t makes L o c k e modern. A
final
word: Locke's proposal will not do. O u r problems with
traditions remain, however. T r a d i t i o n s are still a source of benightedness, chicanery, hostility, and oppression. A n d our moral, religious, and even theoretical traditions are even more fractured today than they were in Locke's d a y . In this situation, examining our traditions remains for m a n y of us a deep obligation, and for all of us together, a desperate need. B u t w e shall h a v e to a c k n o w l e d g e w h a t the thinkers of the Enlightenment would h a v e found appallingly unpalatable; namely, that examination of tradition can take place only in the context of unexamined tradition, and that in our examination, our convictions as to the facts are schooled by our traditions. T h e thinkers of the E n l i g h t e n m e n t hoped to bring about a rational consensus in place of fractured tradition. T h a t hope has failed. In m y j u d g m e n t it was bound to fail; it could not succeed. Y e t we must live together. It is to politics and not to epistemology that w e shall h a v e to look for an answer as to how to do that. "Liberal"
politics
has
fallen
on
bad d a y s recently.
But to
its
animating vision of a society in which persons of diverse traditions live together in justice and friendship, conversing with each other and slowly altering their traditions in response to their conversation - to that, there is no viable alternative.
