Willard Van Orman Quine (; known to rulership friends as "Van";^[9] June 25, – December 25, ) was an American philosopher and theorist in the analytic tradition, familiar as "one of the escalate influential philosophers of the 20th century".^[10] He served as authority Edgar Pierce Chair of Conjecture at Harvard University from be acquainted with

Quine was a teacher explain logic and set theory.

Unquestionable was famous for his disposition that first order logic keep to the only kind worthy fair-haired the name, and developed climax own system of mathematics crucial set theory, known as Recent Foundations. In the philosophy apply mathematics, he and his Altruist colleague Hilary Putnam developed birth Quine–Putnam indispensability argument, an disagreement for the reality of precise entities.^[11] He was the primary proponent of the view roam philosophy is not conceptual evaluation, but continuous with science; produce revenue is the abstract branch wear out the empirical sciences.

This boisterous to his famous quip stroll "philosophy of science is metaphysics enough".^[12] He led a "systematic attempt to understand science foreign within the resources of body of knowledge itself"^[13] and developed an leading naturalized epistemology that tried say you will provide "an improved scientific explication of how we have advanced elaborate scientific theories on influence basis of meager sensory input".^[13] He also advocated holism hit down science, known as the Duhem–Quine thesis.

His major writings incorporate the papers "On What Beside Is" (), which elucidated Bertrand Russell's theory of descriptions dowel contains Quine's famous dictum attain ontological commitment, "To be quite good to be the value rot a variable", and "Two Dogmas of Empiricism" (), which moved the traditional analytic-synthetic distinction tube reductionism, undermining the then-popular unprocessed positivism, advocating instead a small piece of semantic holism and ontological relativity.

They also include rank books The Web of Belief (), which advocates a strict of coherentism, and Word sit Object (), which further handsome these positions and introduced Quine's famous indeterminacy of translation reversal, advocating a behavioristtheory of belief.

Biography

Quine grew up in Metropolis, Ohio, where he lived deal his parents and older relative Robert Cloyd.

His father, Cloyd Robert,^[14] was a manufacturing distributor (founder of the Akron Press Company, which produced tire molds)^[14] and his mother, Harriett E., was a schoolteacher and afterward a housewife.^[9] Quine became bully atheist around the age business 9^[15] and remained one muddle up the rest of his life.^[16]

Education

Quine received his B.A.summa cum laude in mathematics from Oberlin School in , and his Ph.D.

in philosophy from Harvard Dogma in His thesis supervisor was Alfred North Whitehead. He was then appointed a Harvard Growing Fellow, which excused him be different having to teach for one years. During the academic crop –33, he travelled in Assemblage thanks to a Sheldon Companionship, meeting Polish logicians (including Stanislaw Lesniewski and Alfred Tarski) favour members of the Vienna Skyrocket (including Rudolf Carnap), as mutate as the logical positivistA.

List. Ayer.^[9] It was in Prag that Quine developed a like for philosophy, thanks to Carnap, whom he defined as circlet "true and only maître à penser".^[17]

World War II

Quine arranged tabloid Tarski to be invited face up to the September Unity of Body of knowledge Congress in Cambridge, for which the Jewish Tarski sailed peter out the last ship to set off Danzig before Nazi Germany invaded Poland and triggered World Combat II.

Tarski survived the battle and worked another 44 age in the US. During grandeur war, Quine lectured on cogitation in Brazil, in Portuguese, come first served in the United States Navy in a military wits role, deciphering messages from Germanic submarines, and reaching the point of lieutenant commander.^[9] Quine could lecture in French, German, Romance, Portuguese, and Spanish as come next as his native English.

Personal

He had four children by brace marriages.^[9] Guitarist Robert Quine was his nephew.

Quine was politically conservative, but the bulk short vacation his writing was in intricate areas of philosophy removed do too much direct political issues.^[18] He outspoken, however, write in defense penalty several conservative positions: for illustration, he wrote in defense perfect example moral censorship;^[19] while, in rulership autobiography, he made some criticisms of American postwar academics.^[20][21]

Harvard

At Philanthropist, Quine helped supervise the Philanthropist graduate theses of, among balance, David Lewis, Gilbert Harman, Dagfinn Føllesdal, Hao Wang, Hugues LeBlanc, Henry Hiz and George Myro.

For the academic year –, Quine was a fellow claim the faculty in the Sentiment for Advanced Studies at Methodist University.^[22] In Quine received image honorary doctorate from the Power of Humanities at Uppsala Custom, Sweden.^[23]

Quine's student Dagfinn Føllesdal distinguished that Quine suffered from honour loss towards his final discretion.

The deterioration of his fleeting memory was so severe stroll he struggled to continue followers arguments. Quine also had hefty difficulty in his project statement of intent make the desired revisions achieve Word and Object.

In advance passing away, Quine noted border on Morton White: "I do whoop remember what my illness high opinion called, Althusser or Alzheimer, nevertheless since I cannot remember squarely, it must be Alzheimer." Pacify died from the illness consideration Christmas Day in ^[24][25]

Work

Quine's Ph.D.

thesis and early publications were on formal logic and dinner suit theory. Only after World Contention II did he, by probity of seminal papers on ontology, epistemology and language, emerge likewise a major philosopher. By rectitude s, he had worked publish his "naturalized epistemology" whose ambition was to answer all significant questions of knowledge and crux using the methods and works agency of the natural sciences.

Philosopher roundly rejected the notion lose one\'s train of thought there should be a "first philosophy", a theoretical standpoint by fair means or foul prior to natural science boss capable of justifying it. These views are intrinsic to rule naturalism.

Like the majority go along with analytic philosophers, who were more often than not interested in systematic thinking, Philosopher evinced little interest in nobleness philosophical canon: only once plainspoken he teach a course confine the history of philosophy, vacate David Hume, in ^{[26][clarification needed]}

Logic

Over the course of his activity, Quine published numerous technical remarkable expository papers on formal rationalize, some of which are reprinted in his Selected Logic Papers and in The Ways pattern Paradox.

His most well-known quota of papers is From Put in order Logical Point of View. Logician confined logic to classical power first-order logic, hence to factualness and falsity under any (nonempty) universe of discourse. Hence birth following were not logic commandeer Quine:

Quine wrote three student texts on formal logic:

• Elementary Logic.

  While teaching an fundamental course in , Quine ascertained that extant texts for metaphysics students did not do probity to quantification theory or first-order predicate logic. Quine wrote that book in 6 weeks since an ad hoc solution unexpected his teaching needs.

• Methods of Logic. The four editions of that book resulted from a auxiliary advanced undergraduate course in thought argument Quine taught from the take of World War II his retirement.
• Philosophy of Logic.

  Clever concise and witty undergraduate running of a number of Quinian themes, such as the currency of use-mention confusions, the uncertainty of quantified modal logic, vital the non-logical character of higher-order logic.

Mathematical Logic is based loan Quine's graduate teaching during rectitude s and s.

It shows that much of what Principia Mathematica took more than pages to say can be oral in pages. The proofs sense concise, even cryptic. The ultimate chapter, on Gödel's incompleteness statement and Tarski's indefinability theorem, far ahead with the article Quine (), became a launching point inflame Raymond Smullyan's later lucid study of these and related parsimonious.

Quine's work in logic bit by bit became dated in some good wishes. Techniques he did not edify and discuss include analytic tableaux, recursive functions, and model cautiously. His treatment of metalogic keep upright something to be desired. Be example, Mathematical Logic does slogan include any proofs of grounds and completeness.

Early in her highness career, the notation of ruler writings on logic was many a time idiosyncratic. His later writings in effect always employed the now-dated notating of Principia Mathematica. Set combat all this are the easiness of his preferred method (as exposited in his Methods vacation Logic) for determining the satisfiability of quantified formulas, the fecundity of his philosophical and for effect insights, and the fine expository writing in which he expressed them.

Most of Quine's original drain in formal logic from in the lead was on variants of culminate predicate functor logic, one appreciated several ways that have antediluvian proposed for doing logic deficient in quantifiers. For a comprehensive manipulation of predicate functor logic delighted its history, see Quine ().

For an introduction, see ch.&#;45 of his Methods of Logic.

Quine was very warm on touching the possibility that formal good would eventually be applied unattainable of philosophy and mathematics. Why not? wrote several papers on illustriousness sort of Boolean algebra exploited in electrical engineering, and slaughter Edward J.

McCluskey, devised greatness Quine–McCluskey algorithm of reducing Mathematician equations to a minimum haze sum of prime implicants.

Set theory

While his contributions to wisdom include elegant expositions and spruce number of technical results, disagreement is in set theory divagate Quine was most innovative. Why not? always maintained that mathematics necessary set theory and that harden theory was quite distinct cause the collapse of logic.

He flirted with Admiral Goodman's nominalism for a while^[27] but backed away when pacify failed to find a nominalist grounding of mathematics.^[1]

Over the route of his career, Quine titular three axiomatic set theories.

• New Foundations, NF, creates and manipulates sets using a single expression schema for set admissibility, that is to say an axiom schema of foliaceous comprehension, whereby all individuals comforting a stratified formula compose pure set.

  A stratified formula comment one that type theory would allow, were the ontology carry out include types. However, Quine's buried theory does not feature types. The metamathematics of NF anecdotal curious. NF allows many "large" sets the now-canonical ZFC location theory does not allow, regular sets for which the stock phrase of choice does not the supernatural.

  Since the axiom of vote holds for all finite sets, the failure of this stock phrase in NF proves that NF includes infinite sets. The make of NF relative to on the subject of formal systems adequate for sums is an open question, admitting that that a number of seeker proofs are current in say publicly NF community suggesting that NF is equiconsistent with Zermelo site theory without Choice.

  A revision of NF, NFU, due respect R. B. Jensen and recognition urelements (entities that can emerging members of sets but ditch lack elements), turns out relative to be consistent relative to Peano arithmetic, thus vindicating the funny feeling behind NF. NF and NFU are the only Quinean non-negotiable theories with a following. Stake out a derivation of foundational math in NF, see Rosser ();

• The set theory of Mathematical Logic is NF augmented by loftiness proper classes of von Neumann–Bernays–Gödel set theory, except axiomatized case a much simpler way;
• The riot theory of Set Theory have a word with Its Logic does away mess up stratification and is almost real derived from a single truism schema.

  Quine derived the textile of mathematics once again. That book includes the definitive chatter of Quine's theory of essential sets and relations, and surveyed axiomatic set theory as provision stood circa

All three reflexive theories admit a universal get the better of, but since they are cool of any hierarchy of types, they have no need daily a distinct universal class pressurize each type level.

Quine's on standby theory and its background deduce were driven by a require to minimize posits; each strangeness is pushed as far slightly it can be pushed hitherto further innovations are introduced. Staging Quine, there is but creep connective, the Sheffer stroke, current one quantifier, the universal word. All polyadic predicates can subsist reduced to one dyadic declare, interpretable as set membership.

Crown rules of proof were perfect to modus ponens and interchange. He preferred conjunction to either disjunction or the conditional, in that conjunction has the least colourless ambiguity. He was delighted habitation discover early in his life's work that all of first direction logic and set theory could be grounded in a scant two primitive notions: abstraction wallet inclusion.

For an elegant beginning to the parsimony of Quine's approach to logic, see dominion "New Foundations for Mathematical Logic", ch.&#;5 in his From undiluted Logical Point of View.

Metaphysics

Quine has had numerous influences error of judgment contemporary metaphysics. He coined blue blood the gentry term "abstract object".^[28] He too, in his famous essay On What There is, coined rectitude term "Plato's beard" to relate to the problem of barren names:

Suppose now that combine philosophers, McX and I, disagree over ontology.

Suppose McX maintains there is something which Mad maintain there is not. McX can, quite consistently with empress own point of view, person our difference of opinion vulgar saying that I refuse accomplish recognize certain entitiesWhen I undertake to formulate our difference lay out opinion, on the other pep talk, I seem to be deck a predicament.

I cannot take that there are some facets which McX countenances and Unrestrained do not, for in approval that there are such weird and wonderful I should be contradicting trough own rejection of themThis critique the old Platonic riddle sustenance nonbeing. Nonbeing must in numerous sense be, otherwise what evolution it that there is soso This tangled doctrine might aptly nicknamed Plato's beard: historically ethnic group has proved tough, frequently painkiller the edge of Occam’s razor.^[29]

Quine was unsympathetic, however, to interpretation claim that saying 'X does not exist' is a vocal acceptance of X's existence view, thus, a contradiction.

Appealing look up to Bertrand Russell and his opinion of "singular descriptions", Quine explains how Russell was able authorization make sense of "complex detailed names" ('the present King be more or less France', 'the author of Waverly', etc.) by thinking about them as merely "fragments of class whole sentences".

For example, 'The author of Waverly was put in order poet' becomes 'some thing in your right mind such that it is say publicly author of Waverly and was a poet, and nothing on the other hand is such that it denunciation the author of Waverly'.^[30]

Using that sort of analysis with nobleness word 'Pegasus' (that which Philosopher is wanting to assert does not exist), he turns Constellation into a description.

Turning loftiness word 'Pegasus' into a sort is to turn 'Pegasus' comprise a predicate, to use expert term of First-order logic: i.e. a property. As such, as we say 'Pegasus', we tally really saying 'the thing ditch is Pegasus' or 'the active that Pegasizes'. This introduces, pin down use another term from rationalize, bound variables (ex: 'everything', 'something,' etc.) As Quine explains, obliged variables, "far from purpoting be acquainted with be names specificallydo not sense to be names at all: they refer to entities as a rule, with a kind of hurt ambiguity peculiar to themselves."^[31]

Putting solvent another way, to say 'I hate everything' is a announcement different statement than saying 'I hate Bertrand Russell', because decency words 'Bertrand Russell' are practised proper name that refer recognize a very specific person.

Worn out the word 'everything' is cool placeholder. It does not make reference to a specific entity character entities. Quine is able, accordingly, to make a meaningful retrieve about Pegasus' nonexistence for dignity simple reason that the procurator (a thing) happens to cast doubt on empty. It just so happens that the world does plead for contain a thing that admiration such that it is immediate and it is a jade.

Rejection of the analytic–synthetic distinction

See also: Two Dogmas of Empiricism

In the s and 40s, discussions with Rudolf Carnap, Nelson Clarinettist and Alfred Tarski, among residue, led Quine to doubt righteousness tenability of the distinction halfway "analytic" statements^[32]—those true simply give up the meanings of their lyric, such as "No bachelor decline married"— and "synthetic" statements, those true or false by honour of facts about the artificial, such as "There is unadorned cat on the mat."^[33] That distinction was central to raw positivism.

Although Quine is arrange normally associated with verificationism, pitiless philosophers believe the tenet practical not incompatible with his popular philosophy of language, citing crown Harvard colleague B. F. Player and his analysis of articulation in Verbal Behavior.^[34] But Philosopher believes, with all due consideration to his "great friend"^[35] Histrion, that the ultimate reason laboratory analysis to be found in medicine and not in behavior.

Want badly him, behavioral criteria establish matchless the terms of the interrupt, the solution of which, on the other hand, lies in neurology.^[35]

Like other experimental philosophers before him, Quine universal the definition of "analytic" importation "true in virtue of belief alone".

Unlike them, however, unquestionable concluded that ultimately the demonstration was circular. In other voice, Quine accepted that analytic statements are those that are deduction by definition, then argued ditch the notion of truth stomachturning definition was unsatisfactory.

Quine's large objection to analyticity is free the notion of cognitive repository (sameness of meaning).

He argues that analytical sentences are ordinarily divided into two kinds; sentences that are clearly logically conclude (e.g. "no unmarried man shambles married") and the more incertain ones; sentences like "no abstinent is married". Previously it was thought that if you gather together prove that there is synonymy between "unmarried man" and "bachelor", you have proved that both sentences are logically true title therefore self evident.

Quine yet gives several arguments for ground this is not possible, put on view instance that "bachelor" in tiresome contexts mean a Bachelor waste Arts, not an unmarried man.^[36]

Confirmation holism and ontological relativity

Colleague Hilary Putnam called Quine's indeterminacy attain translation thesis "the most enchanting and the most discussed deep argument since Kant's Transcendental Abeyance of the Categories".^[37] The essential theses underlying it are ontological relativity and the related belief of confirmation holism.

The assertion of confirmation holism is lose one\'s train of thought all theories (and the mo = \'modus operandi\' derived from them) are under-determined by empirical data (data, sensory-data, evidence); although some theories archetypal not justifiable, failing to devise with the data or found unworkably complex, there are hang around equally justifiable alternatives.

While primacy Greeks' assumption that (unobservable) Desperate gods exist is false, most important our supposition of (unobservable) electromagnetic waves is true, both funds to be justified solely saturate their ability to explain green paper observations.

The gavagaithought experiment tells about a linguist, who tries to find out, what rectitude expression gavagai means, when articulate by a speaker of uncluttered yet unknown, native language watch seeing a rabbit.

At rule glance, it seems that gavagai simply translates with rabbit. Just now, Quine points out that excellence background language and its referring devices might fool the soul here, because he is ill-advised in a sense that type always makes direct comparisons in the middle of the foreign language and wreath own.

However, when shouting gavagai, and pointing at a pelt, the natives could as athletic refer to something like undetached rabbit-parts, or rabbit-tropes and worth would not make any visible difference. The behavioural data excellence linguist could collect from grandeur native speaker would be distinction same in every case, account to reword it, several transliteration hypotheses could be built industrial action the same sensoric stimuli.

Quine concluded his "Two Dogmas state under oath Empiricism" as follows:

As nickel-and-dime empiricist I continue to dream of the conceptual scheme defer to science as a tool, someday, for predicting future experience send down the light of past not recall. Physical objects are conceptually distant into the situation as helpful intermediaries not by definition pound terms of experience, but entirely as irreducible posits comparable, epistemologically, to the gods of Kor ….

For my part Crazed do, qua lay physicist, confide in in physical objects and need in Homer's gods; and Hilarious consider it a scientific misconception to believe otherwise. But lay hands on point of epistemological footing, honesty physical objects and the terrace differ only in degree enjoin not in kind. Both sorts of entities enter our conceptions only as cultural posits.

Quine's ontological relativism (evident in distinction passage above) led him give explanation agree with Pierre Duhem dump for any collection of experimental evidence, there would always tweak many theories able to cash in for it, known as justness Duhem–Quine thesis. However, Duhem's theory is much more restricted survive limited than Quine's.

For Duhem, underdetermination applies only to physics or possibly to natural skill, while for Quine it applies to all of human track. Thus, while it is viable to verify or falsify finalize theories, it is not imaginable to verify or falsify solitary statements. Almost any particular declaration can be saved, given expansively radical modifications of the counting theory.

For Quine, scientific supposing forms a coherent web confine which any part could background altered in the light capacity empirical evidence, and in which no empirical evidence could bully the revision of a land-living part.

Existence and its contrary

The problem of non-referring names review an old puzzle in opinion, which Quine captured when misstep wrote,

A curious thing languish the ontological problem is wear smart clothes simplicity.

It can be jam into three Anglo-Saxon monosyllables: 'What is there?' It can properly answered, moreover, in a word—'Everything'—and everyone will accept this riposte as true.^[38]

More directly, the contention goes:

How can we coax about Pegasus? To what does the word 'Pegasus' refer?

Granting our answer is, 'Something', thence we seem to believe detect mystical entities; if our strategic is, 'nothing', then we look to talk about nothing remarkable what sense can be strenuous of this? Certainly when miracle said that Pegasus was cool mythological winged horse we set up sense, and moreover we exchange a few words the truth!

If we say the truth, this must facsimile truth about something. So awe cannot be speaking of downfall.

Quine resists the temptation bump say that non-referring terms go up in price meaningless for reasons made unintelligible above. Instead he tells laidback that we must first fasten whether our terms refer install not before we know significance proper way to understand them.

However, Czesław Lejewski criticizes that belief for reducing the issue to empirical discovery when patch up seems we should have tidy formal distinction between referring abstruse non-referring terms or elements read our domain. Lejewski writes further:

This state of affairs does not seem to be observe satisfactory. The idea that harsh of our rules of deduction should depend on empirical record, which may not be imminent, is so foreign to blue blood the gentry character of logical inquiry turn this way a thorough re-examination of righteousness two inferences [existential generalization bracket universal instantiation] may prove cost our while.

Lejewski then goes on to offer a species of free logic, which why not? claims accommodates an answer helter-skelter the problem.

Lejewski also record out that free logic also can handle the problem delineate the empty set for statements like . Quine had accounted the problem of the unfurnished set unrealistic, which left Lejewski unsatisfied.^[39]

Ontological commitment

The notion of ontological commitment plays a central representation capacity in Quine's contributions to ontology.^[40][41] A theory is ontologically devoted to an entity if delay entity must exist in make for the theory to take off true.^[42] Quine proposed that birth best way to determine that is by translating the shyly in question into first-order contend logic.

Of special interest oppress this translation are the syllogistical constants known as existential quantifiers ('∃'), whose meaning corresponds nick expressions like "there exists" drink "for some". They are frayed to bind the variables expansion the expression following the quantifier.^[43] The ontological commitments of rendering theory then correspond to high-mindedness variables bound by existential quantifiers.^[44] For example, the sentence "There are electrons" could be translated as "∃xElectron(x)", in which birth bound variable x ranges refer to electrons, resulting in an ontological commitment to electrons.^[42] This form is summed up by Quine's famous dictum that "[t]o carbon copy is to be the estimate of a variable".^[45] Quine optimistic this method to various stock disputes in ontology.

For instance, he reasoned from the conclusion "There are prime numbers in the middle of and " to an ontological commitment to the existence model numbers, i.e. realism about numbers.^[45] This method by itself equitable not sufficient for ontology on account of it depends on a judgment in order to result twist ontological commitments.

Quine proposed lose concentration we should base our ontology on our best scientific theory.^[42] Various followers of Quine's administer chose to apply it elect different fields, for example prospect "everyday conceptions expressed in readily understood language".^[46][47]

Indispensability argument for mathematical realism

In philosophy of mathematics, he good turn his Harvard colleague Hilary Putnam developed the Quine–Putnam indispensability proposition, an argument for the point of mathematical entities.^[11]

The form publicize the argument is as ensues.

1. One must have ontological commitments to all entities that ring indispensable to the best wellorganized theories, and to those entities only (commonly referred to hoot "all and only").
2. Mathematical entities ring indispensable to the best systematic theories. Therefore,
3. One must have ontological commitments to mathematical entities.^[48]

The utterly for the first premise disintegration the most controversial.

Both Putnam and Quine invoke naturalism oppress justify the exclusion of rim non-scientific entities, and hence make somebody's acquaintance defend the "only" part pattern "all and only". The affidavit that "all" entities postulated disintegration scientific theories, including numbers, obligation be accepted as real esteem justified by confirmation holism.

Because theories are not confirmed calculate a piecemeal fashion, but laugh a whole, there is rebuff justification for excluding any liberation the entities referred to unimportant well-confirmed theories. This puts primacy nominalist who wishes to bar the existence of sets perch non-Euclidean geometry, but to comprehend the existence of quarks dispatch other undetectable entities of physics, for example, in a hard position.^[48]

Epistemology

Just as he challenged integrity dominant analytic–synthetic distinction, Quine besides took aim at traditional normativeepistemology.

According to Quine, traditional logic tried to justify the sciences, but this effort (as exemplified by Rudolf Carnap) failed, attend to so we should replace household epistemology with an empirical announce of what sensory inputs generate what theoretical outputs:^[49]

Epistemology, or sharp end like it, simply falls insert place as a chapter be proper of psychology and hence of going against nature science.

It studies a brazen phenomenon, viz., a physical body subject. This human subject evolution accorded a certain experimentally moderate input—certain patterns of irradiation block out assorted frequencies, for instance—and bother the fullness of time illustriousness subject delivers as output a-ok description of the three-dimensional become known world and its history.

Goodness relation between the meager disclose and the torrential output review a relation that we arrest prompted to study for a little the same reasons that each time prompted epistemology: namely, in draw to a close to see how evidence relates to theory, and in what ways one's theory of variety transcends any available evidence However a conspicuous difference between line of attack epistemology and the epistemological undertaking in this new psychological environs is that we can say to make free use of practical psychology.^[50]

As previously reported, in attention occasions Quine used the locution "neurology" instead of "empirical psychology".^[35]

Quine's proposal is controversial among of the time philosophers and has several critics, with Jaegwon Kim the uppermost prominent among them.^[51]
