Quine s Professional Published and Unpublished Essays

Early in his career, the notation of his writings on logic was often idiosyncratic. His later writings nearly always employed the now-dated notation of Principia mathematica. Set against all this are the simplicity of his preferred method (as exposited in his Methods of Logic ) for determining the satisfiability of quantified formulas, the richness of his philosophical and linguistic insights, and the fine prose in which he expressed them. Most of quine's original work in formal logic from 1960 onwards was on variants of his predicate functor logic, one of several ways that have been proposed for doing logic without quantifiers. For a comprehensive treatment of predicate functor logic and its history, see quine (1976). For an introduction, see chpt. 45 of his Methods of Logic.

Quine wrote this book in 6 weeks as an ad hoc solution to his teaching needs. The four editions of this book resulted from a more advanced undergraduate course in logic remote quine taught from the end of World War ii until his 1978 retirement. A concise and witty undergraduate treatment of a number of quinian themes, such as the prevalence of use-mention confusions, the dubiousness of quantified modal logic, and the non-logical character of higher-order logic. Mathematical Logic is based on quine's graduate teaching during the 1930s and '40s. It shows that much of what Principia mathematica took more than 1000 pages to say can be said in 250 pages. The proofs are concise, even cryptic. The last chapter, on Gödel's incompleteness theorem and Tarski's indefinability theorem, along with the article quine (1946 became a launching point for raymond Smullyan 's later lucid exposition of these and related results. Quine's work in logic gradually became dated in some respects. Techniques he did not teach and discuss include analytic tableaux, recursive functions, and model theory. His treatment of metalogic left something to be desired. For example, mathematical Logic does not include any proofs of soundness and completeness.

Lejewski then goes on to offer a description of free logic, which he claims accommodates an answer to the problem. Lejewski also points out that free logic additionally can handle the problem shredder of the empty set for statements like xFxxFxdisplaystyle forall x,Fxrightarrow exists x,. Quine had considered the problem of the empty set unrealistic, which left Lejewski unsatisfied. 22 Logic edit over the course of his career, quine published numerous technical and expository papers on formal logic, some of which are reprinted in his Selected Logic Papers and in The ways of Paradox. Quine confined logic to classical bivalent first-order logic, hence to truth and falsity under any (nonempty) universe of discourse. Hence the following were not logic for quine: quine wrote three undergraduate texts on formal logic: Elementary logic. While teaching an introductory course in 1940, quine discovered that extant texts for philosophy students did not do justice to quantification theory or first-order predicate logic.

Certainly when we said that Pegasus was a mythological winged horse we make sense, and moreover we speak the truth! If we speak the truth, this must be truth about something. So we cannot be speaking of nothing. Quine resists the temptation to year say that non-referring terms are meaningless for reasons made clear above. Instead he tells us that we must first determine whether our terms refer or not before we know the proper way to understand them. However, czesław Lejewski criticizes this belief for reducing the matter to empirical discovery when it seems we should have a formal distinction between referring and non-referring terms or elements of our domain. Lejewski writes further, This state of affairs does not seem to be very satisfactory. The idea that some of our rules of inference should depend on empirical information, which may not be forthcoming, is so foreign to the character of logical inquiry that a thorough re-examination of the two inferences existential generalization and universal instantiation may prove worth our.

Thus, while it is possible to verify or falsify whole theories, it is not possible to verify or falsify individual statements. Almost any particular statement can be saved, given sufficiently radical modifications of the containing theory. For quine, scientific thought forms a coherent web in which any part could be altered in the light of empirical evidence, and in which no empirical evidence could force the revision of a given part. Quine's writings have led to the wide acceptance of instrumentalism in the philosophy of science. Existence and its contrary edit The problem of non-referring names is an old puzzle in philosophy, which quine captured when he wrote, a curious thing about the ontological problem is its simplicity. It can be put into three anglo-saxon monosyllables: 'What is there?' It can be answered, moreover, in a word—'everything'—and everyone will accept this answer as true. 21 More directly, the controversy goes, how can we talk about Pegasus? To what does the word 'pegasus' refer? If our answer is, 'something then we seem to believe in mystical entities; if our answer is, 'nothing then we seem to talk about nothing and what sense can be made of this?

Citation needed quine finds the notion of such a space problematic, arguing that there is no distinction between those truths which are universally and confidently believed and those which are necessarily true. Confirmation holism and ontological relativity edit The central theses underlying the indeterminacy of translation and other extensions of quine's work are ontological relativity and the related doctrine of confirmation holism. The premise of confirmation holism is that all theories (and the propositions derived from them) are under-determined by empirical data (data, sensory-data, evidence although some theories are not justifiable, failing to fit with the data or being unworkably complex, there are many equally justifiable alternatives. While the Greeks' assumption that (unobservable) Homeric gods exist is false, and our supposition of (unobservable) electromagnetic waves is true, both are to be justified solely by their ability to explain our observations. Quine concluded his " Two dogmas of Empiricism " as follows: As an empiricist I continue to think of the conceptual scheme of science as a tool, ultimately, for predicting future experience in the light of past experience. Physical objects are conceptually imported into the situation as convenient intermediaries not by definition in terms of experience, but simply as irreducible posits comparable, epistemologically, to the gods of Homer.


For my part I do, qua lay physicist, believe in physical objects and not in Homer's gods; and I consider it a scientific error to believe otherwise. But in point of epistemological footing, the physical objects and the gods differ only in degree and not in kind. Both sorts of entities enter our conceptions only as cultural posits. Quine's ontological relativism (evident in the passage above) led him to agree with pierre duhem that for any collection of empirical evidence, there would always be many theories able to account for. However, duhem's holism is much more restricted and limited than quine's. For Duhem, underdetermination applies only to physics or possibly to natural science, while for quine it applies to all of human knowledge.

Although quine is not normally associated with verificationism, some philosophers believe the tenet is not incompatible with his general philosophy of language, citing his Harvard colleague. Skinner and his analysis of language in Verbal Behavior. 20 like other Analytic philosophers before him, quine accepted the definition of "analytic" as "true in virtue of meaning alone". Unlike them, however, he concluded that ultimately the definition was circular. In other words, quine accepted that analytic statements are those that are true by definition, then argued that the notion of truth by definition was unsatisfactory. This criticism of Kant's epistemology was similar to that of the 18th century writer Johann Gottfried Herder, as both individuals found fault in the kantian system for not sufficiently accounting for the dependence of reasoning on language.

Quine's chief objection to analyticity is with the notion of synonymy (sameness of meaning a sentence being analytic, just in case it substitutes a synonym for one "black" in a proposition like "All black things are black" (or any other logical truth ). The objection to synonymy hinges upon the problem of collateral information. We intuitively feel that there is a distinction between "All unmarried men are bachelors" and "There have been black dogs but a competent English speaker will assent to both sentences under all conditions since such speakers also have access to collateral information bearing on the. Quine maintains that there is no distinction between universally known collateral information and conceptual or analytic truths. Another approach to quine's objection to analyticity and synonymy emerges from the modal notion of logical possibility. A traditional Wittgensteinian view of meaning held that each meaningful sentence was associated with a region in the space of possible worlds.

Thesis and early publications were on formal logic and set theory. Only after World War ii did he, by virtue of seminal papers on ontology, epistemology and language, emerge as a major philosopher. By the 1960s, he had worked out his "naturalized epistemology" whose aim was to answer all substantive questions of knowledge and meaning using the methods and tools of the natural sciences. Quine roundly rejected the notion that there summary should be a "first philosophy a theoretical standpoint somehow prior to natural science and capable of justifying. These views are intrinsic to his naturalism. Quine could lecture in French, Spanish, portuguese and German, as well as his native english. Like the logical positivists, quine evinced little interest in the philosophical canon: only once did he teach a course in the history of philosophy, on Hume. Clarification needed rejection of the analyticsynthetic distinction edit see also: Two dogmas of Empiricism In the 1930s and '40s, discussions with Rudolf Carnap, nelson goodman and Alfred Tarski, among others, led quine to doubt the tenability of the distinction between "analytic" statements—those true simply.

He also developed an influential naturalized epistemology that tried to provide "an improved scientific explanation of how we have developed elaborate scientific theories on the basis of meager sensory input." 8 he is also important in real philosophy of science for his "systematic attempt to understand.
