Websln's Satenth Nat Collegiatc Dictionary
Philosophy has its own rechnical vocabulary_ probably more than any other academic field-and philosophers often use ordinary words in special wap. yet dictionaries of philosophy have tended to concentrate on historical obscura, and to ignore many terms in wide conremponrry use. In vain will one look in most other philosophy dictionaries for such terms as ,rigid designator', .veii of ignorance','Godel's proof , or .prisoner's dilemma'. Moreover, other philosophy dictionaries tend toward long definitions that can too easily tempt the student into treating them as a substitute for actually reading philosophy. In this dictionary, Robert Martin works from very different premises. The central aim is to provide a comprehensive and uptdare guide to philosophicnl terms. Definitions are brief, clear and user-friendly. Notes on usage, spelling and pronunciation are included, and there are brief entries on hundreds of the best-known philosophers. Throughout, Martin writes in a style ar once informal and authoritative, enlightening and entertaining, making difficult conceprs intettigible withour distorting them. The Philosopher's Dictionary is an essential reference work for everyone who reads or writes philosophy. Practising philosophers will consult it ofren; students will rely on it for quick reference; anyone interested in philosophy will find ir as interesring ro browse through as it is invaluable for reference.

About This Dictionary PnrlosopHERs H A v E T H E r R o w N t e c h n i c ar lp cabulary-perhaps mor€ of it than in any other academic field-and often use ordinary words in special ways. Thus this dictionary. I have tried to locate terrns in here where you'd likely look for them first, but there is a great deal of cross-reference,in case you look somewhere else. Alphabetization ignores spaces and punctuation. Phrases are defined in entries alphabetized according to the real order of the words: for example, there is an entry defining'general will'among the G's, cross-referencedunder'will, general' among the W's. Contrasting or very closely related terns are defined together: thus'analytic' and'synthetic' are both defined in the entry for 'analytic / synthetic', to which the entry for 'synthetic' will refer you. Slashes are used to separate such related terms. Before the modern era, people were formally referred to often by their lirst names. So, for example, the entry for 'Thomas Aquinas' is alphabetized under the T's (though cross-referenced under the A's). I have often grven philose phers' full names when they are commonly referred to only by a shorter narne. Parentheses tell you what to leave out when mentioning them. For example, J(ohn) L(angshaw) Austin is almost always called J. L. Austin, and we talk of Auguste Comte, not (Isidore) Auguste (Marie Frangois) Comte. Some definitions use words I define elsewhere; where it might be helpful for you to look up these words, they are in sMALL cAptTAIs. For brevity I ignore obvious grammatical variations (for example, 'coNsIsrEtIT' in one definition refers the reader to the entry under 'consistency'). When a term inside a definition is defined elsewhere, but not under its own heading, the entry in which it is defined is noted in
a'See ...'comment. I note related terms which it might be helpful for you to consult in a 'See also ...,comment. I have given spelling variations, warnings about common misspellings, usage directions, and pronunciations, where useful in square brackets.When it would be uncommon, or pretentious, or very diflicult for English speakersro use the original pronunciation of words or names that come from other languages,I have given the best acceptable English (mis)pronunciation. (I ignore the French 'r' and nasalized vowels, for example; but pronounce them if you can.) There is a Greek or l,atin name associatedwith almosr every philosophical concept talked about before 1600, and there is a non-English word for many concepts associated with non-English-speakingphilosophers. I have included non-English words when they are likely to be found unrranslated in English philosophical writing. The non-English terms are in italics,though most of them have been naturalized into working philosophical English and need nor be underlined or italicized in your writing. Some Greek and Latin words have a line over a vowel (example: 'agape');this mark is optional in English writing. To keep this book short enough to be handy, I have kept definitions brief and basic.There is much more to be said! A useful (but cumbersome) reference work, far longer and more detailed than this, is The Enqclopedia of Philosophy (New York: Macmillan, 1967). And, of course, there's no substitute for reading philosophical works themselves. I hope that you'll find this book friendly, informal, and helpful. My aim has been to give definitions that can be understood by people who don't already know what the defined term means. (Surprisingly, other philosophical dictionaries don't seem to have been written with this in mind!) I have tried to include all thc basicphilosophical words, and to be even-handed; but this book must reflect my own philosophical biases and training. If you find unhelpful definitions, or important words left out, or implicit philosophical bias, please write me at the Philosophy Department, Dalhousie University, Halifax, Nova Scoria, Canada B3H

'the Some philosophers think that something called abso lute' exists, basic to the EXrLANATIoNof other things; but perhaps this is only a RETFICATIoN. HEGELidentified the absolute spirit with God, and thought that it manifests itself in developmentsin the world (saeHrsroRrcAt-NTATERTAUSM/ mEeltst*,t).Other philosophers associatedwith this term are ScHELLING and gReoLgy.Sometimes capitalized: 'the Absolute';'Absolute Spirit'. obsolute spo(eondlime The view that space and time exist independently of the objects and eventsin them.

people do (act morality); others thir* that what'r baric to moral theory is the peneonwho acts (rcnNr morality). KANT argued that good actions were those done by people with the right sort of motives, so his ethical theory is a variety of agent morality; the tmureRrANs thought that the basic kind of ethical thought evaluates actions, whatever the motives or moral worth of the people who do them, so their ethics is a variety of act morality. oclion A human action is distinguished from just any bodily movement, usually on the basis that an action must be intended. Thus your accidentally spilling your coffee is not an action; neither is the motion of your tongue while you drink your coffee, because you do not think about that motion, or intend that it be the way it is. ('Act' is used in the same way.) oction-of-o-dishnce The effect that one thing can have on anorher that it is not touching and to which it is not connected by something in-between. Gravitation is an example. Some philosophers and scientists-e.g., LErBNrz-thought that this was impossible. One way they tried to explain gravitation is to suppose that bodies that gravitationally attract each other are connected by some intervening invisible thing that fills the space between them, and transfers the gravitational force. oclionfteory The branch of philosophy that considersquestions about ACTIoN.Examples of these are: What differentiates an action from other movements?Can there be actions that are refrainingp from acting? Where does an action end and its consequences begin? Moral questions (about, for example, ACTS/ oMISSIONS) and the questions of rnnE wrLL and responsibility are sometimes included in action theory. ocliveeulhonosio SeeEUTHANAsTA, ACTTVE / pAssrvE.

ocls/ ommissionrAn act is doing something, by contrast with an omission (or refraining), which is merely failing to do something. some philosophers think that there catt be a morar difference between these even when they have the same outcome.

The distinction arose during the first few decades of the twentieth century when English philosophers (including RUssELL and MooRE) revolted against the dominant HEGEUAN school. ,A,nalyticphilosophers were so-called because they thought that a major part of philosophy is the exeLysls of coNcEprs. Becauseof their frequent emphasis on language, this school is sometimes called 'linguistic philosophy' or 'linguistic analysis'. Impressed by the methods of science, they tended to think that philosophers had no business making substantive claims that are not VERIFIABLE. Nowadays both the analytic and the continental traditions include such a broad variety of approaches that these distinctions aren't very precise. These names tend mostly to be used as derogatory epithets for the competition. Contemporary

analytic philosophen-roughly speaking-are those who have been influenced by EMptRIcIsM,rRAGMATIsM, and LocrcAL POSITIVISM, though few contemporary analytic philoso phers accept all the basic tenets or methodologies of any of these positions. onolylit/ synthrtk These words were introduced by KANT, referring to the difference between two kinds of luocnunNr. Iknt called a judgement analytic when the "pnEDlcATEwas contained in the subject"; thus, for example, the judgement that all bachelors are unm^rried is analytic because the subject ('bachelors') "contains" the predicate ('unmarried'). This possibly makes the notion the same as that of coxcnpMost philosophers think that this distinction is TUALTRUTH. better made in terms of sentences: a sentence is analytic when the meaning of the subject of that sentence contains 'unmarried' is part of the the meaning of the predicate: 'bachelor'. In other words, an analytic sendefinition of tenc€ is one that is true merely because of the meanings of 'It's snowing or it's not snowing' is true merely the words. 'or' and 'not', so because of the meaning of the words perhaps we should count this as analytic too. But since the relevant words in this case are "logical" words, this sentence is more particularly known as a LocIcALTRUTH.A synthetic truth is a sentencethat is true, but not merely becauseof the 'Pigs don't fly' is true partiall1 bemeaning of the words. 'pigs' meant causeof the meaning of the words, of course:if 'woodpeckers', then that sentence would be false. But since 'pig' tells us nothing about flying, this the definition of not is true merely because of the meaning of the sentence words. One can speak also about analytically false sen'There exists a married bachelor'.

But in philosophical usage, an argument is one 'premises';singular 'premise' or or more statements(called 'premiss') advanced in order to support another statement (the conclusion). Thus philosophers need not get angry when they argue. Premises actually support a conclusion only when there is the appropriate sort of logical connection between the premises and the conclusion. In pnoucTM arguments, the conclusion must be true given the truth of the premises; in an tNoucrlvE argument, the truth of the premirer maLes the conclusion more probable. Any deduc' tive aqgument in which the premises really do have the appropriarc logical connection with the conclusion is called a'lralid'argumenq in invalid algumenm, this connection is lacking. A valid argument may, however, fail to support its conclusion because one or more of its premises is false-for example:

ofirhm/tlnim/ognortidsm Atheism is the view that God does not exist. People who have never given a thought to the 'atheists'-the word is matter aren't called used only for pcople who believe there isn't any God. Atheists sometimes (but not always) in addition think that religious practice is foolish, or that the morality fiostered by religion is wrong. Because atheism has been, at times, so unpopular, atheistic philosophers have sometimes disguised their views. LUanother cRETIUSand Huur were probably atheists. RUSSELL, famous atheist, was open about it (and got into trouble). Not every religion includes the belief in God-Buddhism, for example, is sometimes said to be an atheistic religion. Atheism is contrasted with its opposite, theism, the view that God does exist, and also with agnosticism, the view that there isn't any good reason to believe either that God exists 'atheism','theist', or that He doesn't.

A sceptical and frequently anti.intellectual dctOnslruCliOnhm movement which seeks to interpret texts and the positions held in them by "deconstructing" them - showing the hidden presuppositions, prejudices, motives, and political aims behind them. de dido/ dera (Latin: "about what's sud" / "about a thing") Usually a distinction concerning belief. A de re belief is a belief considered with respect to the actual thing that it's about. Thus, if someone mistakenly thinks that the moving thing in the sky he's looking at is a satellite, whereas it's actually a meteor, then he has the de re belief that a meteor is moving in the sky-more clearly: about that meteor, he believes it's moving in the sky above him. But he has the de dicto belief that a satellite is moving in the sky'above him. ['day DIK-tow','day ray'f deducfion / inductionl. In an outdated way of speaking, deduction is reasoning from the general to the particular, and induction is reasoning from the particular to the general. 2. Nowadays, this distinction between kinds of reasoning is made as follows: correct ("valid") deductive reasoning is are reasoning of the sort that if the premises (saaARGUMENT) true, the conclusion must be true; whereascorrect inductive reasoning supPorts the conclusion by showing only that it's more probably rue.

An indefinite description, by contrast, can apply to any one of a 'a number of thingp: tall man'. A famous controversy involving definite descriptions concerns whether or not statements containing them have ExTSTENTIAL IMpoRT: that is, whether a sentencewhose subject is a definite description that refers to nothing is therefore false. Consider the sentence 'The present king of France is bald'; does the fact that there is no present king of France make the sentencefalse? On Russntt.'saccount of the definite description it does. srRAwsoN,however, argues that the existence of the present king of France is merely pRESUpposEo by this sentence, as the statement 'Fred has stopped beating his wife' presupposes that Fred had been beating her. If what the statement presupposesis not true, then the statement itself is neither true nor false. definilionA procedure for giving the meaning of a word or phrase. There are various kinds of definition, including: L. Vnbal dcfinition: using other words, giving synonymous words or phrases.

There is some debate about how (and whether) this view can be JUSTTFTED l. The view that at least some events are not fully caused is called 'indeterminism'. Determinism is usually a IRESUIrOSTTION of science; KANT thought it was NECESSARY; but quantum physics saysthat it is false.

thc two sentences'It's raining'and'It's snowing'. Two sentences connected in this way are called'disjuncts'. It is often thought that there are two sorts of disjunction ambiguously expressedby'or' in English. (1) The exclusivedisjunction is true when one of the disjuncts is true and the other false, and false otherwise (when both are true, or when both are false). (2) The inclusive disjunction is true when one or both of the disjuncts are true, and false only when both of the disjuncts are false. Suppose, then, that both snow and rain 'It's snowing or it's are coming down at once. Is the sentence 'or' raining' true? If this is taken to be inclusive, it's true; if exclusive, it's false.

doublccffod The doctrine of double effect holds that, although it is always wrong to use a bad means to a good end (saauNo / MEANs),one may act to bring about a good result when also knowingly bringing about bad results, under the following conditions: (l) The bad result is not caused by the good result-both are caused by the action (thus 'double effect'); (2) there's no way of getting the good result without the bad; (3) the good result is so good that it's worth accepting the bad one. For example, a dentist is allowed to drill, and thus cause some pain (the bad result) for the sake of dental improvements (the good result), since these conditions hold-most notably (l): the pain doesn't cause the improvement-both are results of the drilling. This principle is associated with Catholic morality, and has been applied most frequently in contexts of medical ethics. It is disputed by some philosophers, who sometimes argue that the distinction between double effect and bad means / good end is artificial and not morally relevant. doubt fio doubt something can mean either to be uncertain or undecided about it, or to believe that it is false. When philosophical scnrrtcs present arguments for doubting ordinarily acceptedstatements,they may attempt to show that one should be uncertain or undecided about them, or should actually think they are false.

By contrast, a tree that in fact is thirty-three merers high could still be a tree if it weren't thirty-three meters high; thus this characteristic is accidental. (Note that'accident' and'accidental' don't have their ordinary meanings in this philosophical use.) Some philosophers think that the essence/ accident distinction does not concern the real characteristics of something, but is only a consequence of the words we apply to them: being a plant is said to be an essential characteristic of a tree only becauseit's part of the definition of 'tree'.

For example, some ethical naturaliststhink that'the right act'means 'the act that produces the most happiness'.Ethical supernaturalism is the view that ethical properties really are properties having to do with the supernatural or divine: for example, the view that calling an action good is the same as saying that it conforms to the will of God. Nonnaturalists deny that ethical words are equivalent in meaning to words that name the natural (or supernatural) world, though good things may as a matter of fact share some physical properties. They claim that ethical properties are basic properties on their own, not really properties in some other realm. The Open Question Argument, due to G. E. MooRE, argues against ethical naturalism by claiming that one might find that something had any natural property you might name, but still find it an open question (that is, a question not yet settled) whether that thing had an ethical property. Moore thought that any reasoning which based on the false assumption that ethical propertieswere actuallynarural properties committed what he called the "naturalistic fallacy."

Political freedom is what people have insofar as they are unrestricted by laws,or insofar as they haveRIGHTS. What constitutespolitical freedom, and to what extent it is a good thing, is a central concern of political philosophy. 3. A variable is free when it is unbound (seesyMBoLSoF qUANTIHEDLoGIC). problemSince public goods can be enjoyed even by free-rider those who do not participate in payrng fcr them, it seems rational firr each person to avoid contributing to a public good (if possible) but to free-ride on the contributions of others. But if everyone did this, the public good would not be provided. This is a general problem in social philosophy which has the fiorm of the pRrsoNER's DILEMMA. freewill Free will (or rnnnnorral) is the supposed human characteristicthat our decisionsand actions are sometimesentirely (or at least partially) "up to us'-not forced or DETERMINEDby anything internal or external to us. \4b can then either do or not do x-we have alternatives. It seems that only if we have free will can we be ntspoNstsLnficr what we do. But if determinism is true, then everything must be the way it is given its previous cAUSES, including all our actions and decisions: because these causesare themselvesdetermined by still earlier causes,ultimately whatever we decide or do is determined by events that happened a long time ago, and that are not up to us. Thus, it seemsthat determinism is incompatible with free will. There are three main responsesto this apparent problem: (l) Hard determinists accept determinism, so deny free will. (2) LIBERTARTANs accept free will, so deny determinism, at least for some human events(seecoNrRn{AUsAL rnnEoou). Both libertari anism and hard determinism are incompatibilist (seecorvr97

(3) Soft Determinists are compatiblists, in that they attack the reasoning above, and argue that otrr actions might be determined, but also free in some sense-that a determined action might nevertheless be up to the doe4, and one that the doer is morally responsible ficr-when ids determined but not compelled (saecourulsloN). troge, Gottlob (184&1925) German logician and philosopher of language, the founder of modern mathematical logic.

Functionalists tend to be token (scarypn / rorpll) MATERIALISTS, becausethey think that a particular internal state described functionally would be a particular physical state of the person's brain, though each type of mental state need not correspond to a type of physical state (see,by analogy, the can-openerexample, in FUNCTIoNAL KIND). funclionolkindn functional kind is a categorization in terms of what things can do-what their cause-andeffect relations with the world are-and not in terms of what they are made of, or how they are constructed. 'Can opener', fior example, names a functional kind, becausea can opener is anything whose operations result in a can being opened; this kind admits a wide variety of different physical kinds of things (compare an old-fashioned lever-tool, the can opener you turn, the electric can opener).

implicofion / infusnto l. Implication is a logical relation that holds between two statements when the second follows pn' from the first. The first is then said to'imply'the DUCTIvELY second. This relation is sometimes called'implication'' Be careful not to confuse'implication' with'inferencei: the first is a relation between statements,but the second is something people do, when they reason from one statement to another (which the first statementimplies). A rule of inference is an acceptableprocedure for reasoning from one set of statementsof a Particular form to another statement' 2' Sometimes a sentence'implies'what it doesn't literally state. For example, if I said "Fred is now not robbing banks," I imply that at one time he was robbing banks. This sort of implicature is sometimescalled'conversational'or'contextual' implicature, to disting uish it from'logical' implicature' 3. For a different sort of use' sd' (See also PRESUPPOSITIoN') 'material implication' and 'strict implication', in coNDITIONAL.

Does this show that the theory is wrong? A second way innocence and guilt enter into a philosophical argument is in the theory of the "just war." Many people are willing to allow that going to war under some circumstancesis morally justified; but in every war innocent people are hurt and killed. Does this show that it's acceptableto harm innocent people? Or that there's some'Justwar" theory? thing wrong with 'in fact' or 'in practice'.

Intentionality is problematic becausethe items we think about do nor seem to be identical to things in the external world. Thus if you think Santa Claus lives at the north pole, your thought is about Santa-it has Santa as its intentional object-even though (bad news) there is no Santa.

A standard objection to this commonsenseposition is that it's hard to see how this sort of causal interaction could take place, since the mental and the physical work according to their own laws: how could an electrical impulse in a (physical) nerve cell causea non-physicalpain in a mind? Perhaps this even violates the law of conservation of energy.

LocKE are associated with intuitionism about certain kinds of knowledge. Ethical intuitionism is the position that ethical truths are intuited. MooRE, for example, held that there is a special sort of facility for intuiting ethical truths. Nowadays, ethical theorists mostly doubt this, but many rely on what they call ethical intuitions (i.e., ethical reactions not based on theory or reasoning) as data to coNFIRMethical theories anyway.Intuitionism in mathematics has a rather special meaning: it holds that any sort of mathematical entity exists only if it is possible to give a coNSTRUcrIvE pnoor of it.

Ethical knowledge can be derived merely from the a priori form any ethical ASsERTtoNmust have: it must be UNIvERSALIZABLE-thatis, rationally applicable to everl'one. Kant argued that this is equivalent to saying that the basic ethical truth was that everyone must be thought of as an end, never merely as a means (seeaLsoCATEGORICAL/IlypoTHETICALIMPERATIVE).Kant's ethical theory has become a major consideration in contemporary ethics. korno In Hinduism and Buddhism, harma is the sum of the results of one's actions, and is supposed to determine one's destiny, both in this life and in future RETNCARNATIoNS.

motoriolimThe ordinary meaning of this term is the desire for consumer goods, comfcrt, and money, rather than for more "spiritual" goods. But as a philosophical term, it means something quite different: it is the philosophical position that all that exists is physical.LUcRETrus and Honnrs are rwo of the many philosophers associatedwith this position. Materialists about mind sometimes argue that apparently non-physical things like the soul or mind or thoughts are actually material things (saeloENrrry rHEoRy).Central-state materialists identify mental eventswith physical eventscen'tral in the body (i.e.,in the nervoussystem).Some materialists, however, think that categorizing things as mental is altogether a mistake (like believing in ghosts), and that mental eventsdo not exist and this sort of talk ought to be eliminated as scienceprogresses.They are called 'eliminative materialists'.The terms'materialism' and'physicalism' are usually used as synonyms,though 'physicalism'sometimes means the position that everything is explainable by physics.For the distinction between type and token materialism, sceTypEl ToKEN.See also DIALEcTtcAL MATERTALISM, HISTORICAL MATERI ALISM/IDEALISM.

In other words, Y can't be without X. Thus the fact that something is a pig is not necessaryfor that thing to be an animal, for something can be an animal but not a pig.

It is difficult to know, howevel how much of this is due to Plato, and how much to Socrates. Plato's best-known doctrine is the theory of the "forms" or "ideas": these are the general or perfect versions of characteristics we ordinarily encounter (seePLATONIC FoRMS).To understand ordinary experience, Plato argued, we must first have understanding of these forms, and this must be INNATE,not given by experience.

[usually'PRY-ma Fr\Y-sha'or '-shee'] primcly/secondory /leiliuy quolitiesLocKE (and others) argued that some characteristics we perceive are really, as perceived,in external objects(the primary qualities),whereas others (the secondaryqualities) don't exist as perceivedin the real world, but are just powers of external objects to produce ideas in us which don't resemble what's out there. For example, the dimensions of something are really objective characteristicsof it, but its colour is not really out there; we atffibute colours to things just because of sensations causedin us by some other real (primary) characteristics.In addition, sometimes tertiary qualities are distinguished.

probobiliry Something is probable when it is neither impossible nor definite, but likely to some degree. Probability is a measureof how probable something is: when this is given a number, it's usually on a scale from 0 (impossible) to I (definite). To say that something is probable may be to say that it has a probability of more than .5, thus, becausethe probability of a fair die coming up six is about . l7 ( I / 6), we wouldn't say that it's probable it will come up 6. There has been philosophical controversyabout what it really means to say that an event has a certain probability.

Must punishment be unpleasant?If so, then a judge who sentencedsomeone to not-unpleasantcorrective therapy wouldn't be punishing. Must punishment be given in response to a previous bad act? But this would mean that a jail sentence given to an innocent person, either by mistake or to set an example for future wrongdoers, wouldn't count as punishment. A continuing philosophical problem is the attempt to justify the existenceof punishment, either in the casesof legal, stateimposed punishment, or in personal instances,as when a parent punishes a child.

A civil right is a right that is (or ought to be) guaranteed and enfiorced by Sovernment. (Nobody thinks that government ought to enfcrce all our rights.

sellfulfillingbelief A belief that makesitself true, or tends to. For example, the belief that other people think you're strange will often make you act strangely,and will as a result make people think you are strange. On a positive note, the belief that you will do well in an exam will sometimes be self-fulfilling, if as a result of this belief you go irrto the exam relaxed and confident, and thus do well. The belief that you have a belief is self-fulfilling (having that belief makes it true). Also called'self-fulfilling prophecy'.

symboh of quontifior logic Predicates (or predicare-lerters) srand for properties (seeeuAt-rry / ATTRTBUTE / pRopERTy):ficr example, suppose 'B' stands for the property of being bald. Constants stand for particular tNotvtouALS.If ,f' stands for Fred, 'Bf' stands for the sentence,'Fred is bald'. Variables stand for any individual thing. They are said to be ,bound' by quantifiers. The two quantifiers are rhe universal quantifier ('all') and the existentialquantifier ('some',i.e., 'at least one'), sometimes symbolizedby 'V' and 'l', respectively. Thus in '(fx)(Bx)', 'x' is a variable bound by the universal quantifieq and the sentencemeans 'Everything is bald'. '(3x)(Bx)' means 'Something is bald'. An alternativeway to symbolize that universal sentenceis '(x)(Bx)'. '(Bx)' all by itself is not a meaningful sentence-it's called an 'open' sentence, because it lacks a quantifier, so the variable is unbound (also called'free'). The equalssign (=) symbolizes identity: 'a = b' means'a is identical with b'. The iota-operator 'r' (sometimes upside-down) symbolizes the DEFINTTE DEscRJprroN, so '(tx)(Bx)= f' means'The one and only thirig thing that is bald is Fred'. '(y!x)' (sometimesread 'E shriek x') means 'There exists exactly one rhing'; so '(y!x)(Bx)' is the false statement that there exists exactly one bald thing. symbols of ssnfsntiol logit ttre symbols used to stand for logical TRLTTH ruNCTIONALconnections between sentencesin snNTENTIALLoclc.

Sayingthat a relation is 'commurative' is the sameas sayingit's 'symmetric'. sympofiy / ompothy / benevolence These three rerms are often used synonymously,but sometimesthere is a subtle difference: Sympathy is the act of taking on the same feeling another person has, or of feeling as they would feel.

All three of these are sometimes thought to provide a foundation for ethics, as opposed to mere self-interest. sympathy / empathy 'synchronic' synchronic/diochronic means ,ar the same time'; 'diachronic' 'at means different times'.

Pragmatictheory of truth: Something is true when it is useful to believe(everything considered,and in the long run). This doesn't mean that anything you'd like to believe is therefore true: usefulnessis understoodin terms of allowingus to make successfulpredictions, and in general to function well in life. Redund,ancy theoryof truth:'It's true that it's raining' means 'Us raining'. That's all there is to say about no more than 'true'; truth is not a mystery.(There are genuine questions, however,about how we find things out.) Snnantic theory of truth: Truth is a property of certain sentences.Which ones, in general? To give an account of what it is, in a particular language, to be true, one should (in theory) give a list of conditions, one for eachsentencein that language, which obtain IF AND oNLYIF (seeucoNolrIoNAL) that sentenceis true. Thus, part of the list for English (written 'Snow is white' is true if and only in English) would contain: if snow is white. e truth-function is a TNCTIoN whose argutrulh-functionoliry ments and values are Truc and Fabe. Thus, a sentence con'and' is a structed out of two sentencesconnected with truth-function when its truth or falsity depends systematically on the truth or falsity of the comPonent sentences,and on nothing else (it's true whenever both components are true, false otherwise). When a sentence of this sort is a 'and' is said to be used truth-functionally. truth-function, But'and' sometimes isn't used truth-functionally, as when it's used to mean 'and then'.

A truth of reason is a truth that can be discovered by the operations of puREREASoN alone, that is, which does not rely on sense€xperience. Thus this is synonymous with 'a priori truth'.

In elections with many voters, the odds are extremely small that your vote will make any difference to who wins, so even if you care very much who wins, there's no point in voting. This is true also of every other potential voter.So it seemsto follow that there's no point in anyone's voting. 2. Suppose there are three people (call them 1, 2, and 3) who disagree about the relativevalue of three actions (call them A, B, and C): P e r s oI np r e f e rAst o B ,o n dB f o C . P e r s o2np r e f e rBst o [ , o n dI t o A . P e r s o3np r e f e rCst o A , o n dA t o B . Suppose they agree to decide on what to do by voting on these actions two at a time. First they vote on A and B: 1 and 3 vote firr A. Next they vote on B and C: I and 2 vote firr B. Last they vote on C and A: 2 and 3 vote for C. Each "pairwise" decision has a majority favourablevote; yet this clearly does not decide matters.This example showsthe surprising result that in certain caseseven a majority vote of a group does not give a clear answer about what to do. This is also known as the 'Condorcet paradox', named ficr the Marquis de coNooRcnr who wrote about it. It has been generalized by Kenneth Arrow (b. f921) into the central problem of socteL cHoICE THEoRY.Arrow's Theorem shows that there is no rule for social choice that satisfies certain apparently minimal conditions fior rationality and DEMocRAcY.

It seems that a statement with this characteristic might nevertheless be false, but some philosophers of science think that warranted assertibility is really all that we mean by 'truth' in science;this is a kind of scientific antirealism (seeREALTSM / ANTTREALTSM), wox0x0mpl0See"aett OFwAx" EXAMPLE.

Greek philosophel Zenoof [leo (5th century B.C.) PRE-socRArtc student of reRunNIDEs,best known ficr his PARADoxES, which seemed to disprove the existenceof motion. ZenoiporodoxImagine a tortoise in a race with speedsterAchil' les, with the tortoise starting closer to the goal line. When Achilles has reached the point at which the tortoise started, the tortoise has gone a little further; when Achilles reaches this further point, the tortoise has advanced again; and so on. The ABsuRDconclusion is that Achilles will never pass the tortoise. zENo oF ELEA,who produced this PARADox, concluded that this shows there is no such thing as motion; but there are other waysof dealing with the paradox.
