Gideon Rosen: Quine and the Revival of Metaphysics: Quine's critique of Carnap's positivism and Quine's alternative account of scientific and philosophical methodology set the stage for the revival of metaphysics in the 1970s and 80s. The key ingredients in this transition were (a) Quine's insistence that theory choice in the sciences is governed by holistic, pragmatic considerations, (b) his claim that the sciences nonetheless give us reason to believe in the items they posit, and (c) his insistence that theory choice (...) in philosophy is continuous with scientific theory choice in all respects. The chapter presents Quine's account of theory choice and highlights the respects in which post‐Quinean metaphysics owes its methodological self‐conception to Quine's work. (shrink)

In comparing his conception of empiricism with that of other like-minded philosophers at the end of his 'Two Dogmas of Empiricism,' W. V. Quine famously emphasized the broader scope of his pragmatist commitment in these terms:Carnap, Lewis, and others take a pragmatic stand on the question of choosing between language forms, scientific frameworks; but their pragmatism leaves off at the imagined boundary between the analytic and the synthetic. In repudiating such a boundary I espouse a more thorough pragmatism.Such remarks have (...) resulted in Quine's work being associated with the American pragmatist tradition, where he is viewed as either continuing or reviving some of the main themes and issues representative of..

Dagfinn Føllesdal: “Developments in Quine's Behaviorism”: Quine insisted throughout his life that he was a behaviorist. He began briefly as an “ontological behaviorist,” that is, he held that there is nothing mental. However, very early he switched to evidential behaviorism: the view that behavior provides the only evidence we have for the mental and its properties. Ultimately, Quine's behaviorism springs from his empiricism. All knowledge about the world around us and about other people reaches us through our senses: “Behaviorism, as (...) far as I'm concerned, is only an intersubjective empiricism.” Quine applied this to language and communication. His acute problem awareness led him from the discussion of stimuli in Word and Object to a much more refined behaviorism in his latest works, in which full‐fledged perception and the individuation of the world into objects play a crucial role.

This paper develops a new version of instrumentalism, in light of progress in the realism debate in recent decades, and thereby defends the view that instrumentalism remains a viable philosophical position on science. The key idea is that talk of unobservable objects should be taken literally only when those objects are assigned properties (or described in terms of analogies involving things) with which we are experientially (or otherwise) acquainted. This is derivative from the instrumentalist tradition in so far as the (...) distinction between unobservable and observable is taken to have significance with respect to meaning. (shrink)

In retrospecting "Two Dogmas" I find myself overshooting by twenty years. I think back to college days, 61 years agao. I majored in mathematics and was doing my honors reading in mathematical logic, a subject that had not yet penetrated the Oberlin curriculum. My new love, in the platonic sense, was Whitehead and Russell's Principia Mathematica.

Modern empiricism has been conditioned in large part by two dogmas. One is a belief in some fundamental cleavage between truths which are analytic, or grounded in meanings independently of matters of fact, and truth which are synthetic, or grounded in fact. The other dogma is reductionism: the belief that each meaningful statement is equivalent to some logical construct upon terms which refer to immediate experience. Both dogmas, I shall argue, are ill founded. One effect of abandoning them is, as (...) we shall see, a blurring of the supposed boundary between speculative metaphysics and natural science. Another effect is a shift toward pragmatism. (shrink)

My view of science involves both relativistic and absolutistic strains. I shall try to sort them out.

Quine's areas of interest are panoramic, as this lively book amply demonstrates.

Naturalism holds that there is no higher access to truth than empirically testable hypotheses. Still it does not repudiate untestable hypotheses. They fill out interstices of theory and lead to further hypotheses that are testable.A hypothesis is tested by deducing, from it and a background of accepted theory, some observation categorical that does not follow from the background alone. This categorical, a generalized conditional compounded of two observation sentences, admits in turn of a primitive experimental test.The observation sentences themselves, like (...) ape cries and bird calls, are in holophrastic association with ranges of neural intake. Denotation of determinate objects figures neither in this association nor in deducing the categorical from the scientific hypotheses. Hence the indeterminacy of reference; ontology is purely auxiliary to the structure of theory. Truth, however, is seen still as transcendent at least in this sense: we say of a superseded scientific theory not that it ceased to be true, but that it is found to have been false. (shrink)

W. V. Quine is one of the most eminent philosophers alive today. Now in his mid-eighties he has produced a sharp, sprightly book that encapsulates the whole of his philosophical enterprise, including his thinking on all the key components of his epistemological stance--especially the value of logic and mathematics. New readers of Quine may have to go slowly, fathoming for themselves the richness that past readers already know lies between these elegant lines. For the faithful there is much to ponder. (...) In this short book, based on lectures delivered in Spain in 1990, Quine begins by locating his work historically. He provides a lightning tour of the history of philosophy (particularly the history of epistemology), beginning with Plato and culminating in an appreciative sketch of Carnap's philosophical ambitions and achievements. This leads, in the second chapter, to an introduction to Quine's attempt to naturalize epistemology, which emphasizes his continuities with Carnap rather than the differences between them. The next chapters develop the naturalistic story of the development of science to take account of how our conceptual apparatus is enhanced so that we can view the world as containing re-identifiable objects. Having explained the role of observation sentences in providing a checkpoint for assessing scientific theories, and having despaired of constructing an empirical criterion to determine which sentences are meaningful, Quine in the remaining chapters takes up a variety of important issues about knowledge. He concludes with an extended treatment of his views about reference and meaning and his attitudes toward psychological and modal notions. The presentation is distinctive, and the many small refinements of detail and formulation will fascinate all who know Quine's philosophy. (shrink)

When we think of scientific realism, there seem to be to ways to conceive of what it is about. The first is to see it as a view about scientific theories; the second is to see it as a view about the world. Some philosophers, most typically from Australia, think that the second way is the correct way. Scientific realism, they argue, is a metaphysical thesis: it asserts the reality of some types of entity, most typically, unobservable entities. I agree (...) that scientific realism has a metaphysical dimension, but I have insisted that it has other dimensions too. In my (1999), I took scientific realism to consist of three theses (or stances). (shrink)

Recent literature on Bohm's alternative to mainstream quantum mechanics may create the misleading impression that, except for perfunctory dismissals, the theory was ignored by the physics community in the years immediately following its proposal. As a matter of fact, Einstein, Pauli, and Heisenberg all published criticisms of Bohm's theory, explaining their reasons for not accepting the theory. These criticisms will be discussed and evaluated in this article.

In place of earlier instrumentalist and phenomenalist interpretations of science both Quine and Sellars have developed highly influential realist positions centering around the doctrine that accepting a theory as explanatory and irreducible rationally entails accepting the entities posited by the theory. A growing reaction against this realism is partially based on perceived inadequacies in the doctrines of Quine and Sellars, but even more on reconstructions of scientific explanations which do not involve such ontic commitments. Three types of anti-realistic positions are (...) considered and criticized. Hesse's neo-Duhemian position couples a statistical theory of inference to a downgrading of purely theoretical statements. Sneed uses the method of axiomatrization through set-theoretic predicates to supply a reconstruction of Kuhn's account of scientific development. Here Ramsey-reduction sentences serve to eliminate purely theoretical terms. The longest section deals with van Fraassen's semantic model based on a state-space representation of scientific theories and the use of this model in interpreting quantum mechanics. It is argued that the model is valuable, but that the anti-realist interpretation accorded it is not justified and entails serious inconsistencies. (shrink)

Despite the renown of ‘On Denoting’, much criticism has ignored or misconstrued Russell's treatment of scope, particularly in intensional, but also in extensional contexts. This has been rectified by more recent commentators, yet it remains largely unnoticed that the examples Russell gives of scope distinctions are questionable or inconsistent with his own philosophy. Nevertheless, Russell is right: scope does matter in intensional contexts. In Principia Mathematica, Russell proves a metatheorem to the effect that the scope of a single occurrence of (...) a description in an extensional context does not matter, provided existence and uniqueness conditions are satisfied. But attempts to eliminate descriptions in more complicated cases may produce an analysis with more occurrences of descriptions than featured in the analysand. Taking alternation and negation to be primitive (as in the first edition of Principia), this can be resolved, although the proof is non-trivial. Taking the Sheffer stroke to be primitive (as proposed by Russell in the second edition), with bad choices of scope the analysis fails to terminate. (shrink)

W. V. Quine describes himself as a “robust realist” about physical objects in the external world. This realism about objects is due to Quine's naturalism. On the other hand, Quine's naturalistic epistemology involves a conception of objects as posits that we introduce in our theories about the world. This conception of objects can be seen as anti-realist rather than realist. In this article, I discuss the questions whether there is a tension between Quine's realism and his epistemological conception of objects, (...) and how Quine's conception of objects should be understood if he is also to be regarded as a realist. I also address the question whether Quine should be placed on the realist or the anti-realist side of the current realism debate. I argue that Quine's conception of objects as posits is a general account of the nature of objects, and that this account does not conflict with Quine's realism as long as this realism is properly understood. I also argue that Quine cannot be placed on either side of the contemporary realism debate, since his realism is not metaphysical realism and his conception of objects is not an anti-realist doctrine according to which objects would be less than real.

Gary Ebbs: Quine's Naturalistic Explication of Carnap's Logic of Science: If one studies Quine's epistemology without appreciating its deep connections to Carnap's logic of science, one can easily get the impression that unlike Carnap, Quine aims to preserve and clarify the traditional empiricist idea that our best theories of nature are justified by, or based on, our sensory evidence, and are for that reason likely to be true. Quine writes, for instance, that [The] human subject is accorded a certain experimentally (...) controlled input—certain patterns of irradiation in assorted frequencies, for instance—and in the fullness of time the subject delivers as output a description of the three‐dimensional external world and its history. The relation between the meager input and the torrential output is a relation that we are prompted to study for somewhat the same reasons that always prompted epistemology; namely, in order to see how evidence relates to theory, and in what ways one's theory of nature transcends any available evidence. Commenting on this and similar passages in Quine, Barry Stroud writes: … the question Quine poses in terms of the “underdetermination” of the “torrential output” by the “meager input” makes essential use of a notion of epistemic priority. It is because the “information” we get at “input” does not uniquely determine the truth of what we assert as “output” that we must explain how we get from the one to the other. I argue that despite its superficial plausibility, this interpretation of Quine is mistaken: following Carnap, yet also radically transforming his views, Quine takes our best current theory as our ultimate arbiter of truth. The goal of Quine's naturalistic account of the relationship between theory and evidence is not to show that our best theories of nature are justified by our sensory evidence, but to show that we can describe science from within science itself in a way that mirrors and thereby clarifies his doctrinal principle that we can only judge truth from the standpoint of our best current theory.

Structural realism is considered by many realists and antirealists alike as the most defensible form of scientific realism. There are now many forms of structural realism and an extensive literature about them. There are interesting connections with debates in metaphysics, philosophy of physics and philosophy of mathematics. This entry is intended to be a comprehensive survey of the field.

The realist programme has degenerated by now to the point where it is quite beyond salvage. A token of this degeneration is that there are altogether too many realisms. It is as though by splitting into a confusing array of types and kinds, realism has hoped that some one variety might yet escape extinct. I shall survey the debate, and some of these realisms, below. Here I would just point out the obvious; that in so far as the successes of (...) science mount while realism continues to decline we must conclude that scientific success lends no support to realism. Since it is unlikely to support anti-realism, we have some reason to suspect that the philosophical debate over realism does not concern issues that can be settled by developments in the sciences, no matter how successful science may be. Further, since that success grounds a culture of acceptance for science and its entities, we have reason to believe that the existence of those entities is also not actually the issue that concerns realism. Afortiori, it is not the issue that concerns anti-realism either; nor, I might add, is anti-realism the winner in the philosophical debate that realism has lost. (shrink)

SummaryStarting with Descartes, epistemology has been almost entirely based on first person knowledge. We must begin, according to the usual story, with what is most certain: knowledge of our own sensations and thoughts. In one way or another we then progress, if we can, to knowledge of an objective external world. There is then the final, tenuous, step to knowledge of other minds.In this paper I argue for a total revision of this picture. All propositional thought, whether positive or skeptical, (...) whether of the inner or of the outer, requires possession of the concept of objective truth, and this concept is accessible only to those creatures in communication with others. Third person knowledge – knowledge of other minds – is thus conceptually basic. But such knowledge is impossible without knowledge of a shared world of objects in a shared time and space. Thus the acquisition of knowledge is not based on a progression from the subjective to the objective; it emerges holistically, and is interpersonal from the start. (shrink)
