The Polish logicians' propositional calculi, which consist in a distinct synthesis of the Fregean and Boolean approaches to logic, influenced W. V. Quine's early work in formal logic. This early formal work of Quine's, in turn, can be shown to serve as one of the sources of his holistic conception of natural language.

In this paper, I shall consider the challenge that Quine posed in 1947 to the advocates of quantified modal logic to provide an explanation, or interpretation, of modal notions that is intuitively clear, allows “quantifying in”, and does not presuppose, mysterious, intensional entities. The modal concepts that Quine and his contemporaries, e.g. Carnap and Ruth Barcan Marcus, were primarily concerned with in the 1940’s were the notions of (broadly) logical, or analytical, necessity and possibility, rather than the metaphysical modalities that (...) have since become popular, largely due to the influence of Kripke. In the 1950’s modal logicians responded to Quine’s challenge by providing quantified modal logic with model-theoretic semantics of various types. In doing so they also, explicitly or implicitly addressed Quine’s interpretation problem. Here I shall consider the approaches developed by Carnap in the late 1940’s, and by Kanger, Hintikka, Montague, and Kripke in the 1950’s, and discuss to what extent these approaches were successful in meeting Quine’s doubts about the intelligibility of quantified modal logic.

Quine’s thesis of translational indeterminacy stands as one of the most central, surprising, and influential results of analytic philosophy in the twentieth century. The suggestion that the meaning of linguistic terms and sentences, as shown in the situation of radical translation, is systematically indeterminate and undetermined by actual speech practice, has for decades engendered thought and reflection on the nature and basis of linguistic meaning. And even beyond this surprising moral itself, Quine’s theoretical use of the radical translation scenario has (...) been wholly or partly responsible for a wide variety of theoretical programs in analytic philosophy since the middle of the last century, including Davidsonian semantics, Dummett’s consideration of the form and shape of knowledge about meaning, Rorty’s celebration of “philosophy without foundations,” and, more recently, Brandom’s pragmatist project of analyzing the roots of meaning and normativity in intersubjective and socially regulated speech behavior. On many retellings of the history of the analytic tradition, the suggestion that the philosophical analysis of language and meaning depends on reflection about the structure of intersubjective linguistic practice marks a general sea change in the methodological self-conception of analytic philosophy, away from the brands of metaphysical, epistemological, or purely syntactic analyses that had characterized its earlier projects, and toward the more concrete, pragmatic, and empirically influenced reflective practice that philosophers inherit today.

This paper concerns the debate on the nature of Rudolf Carnap'sproject in his 1928 book The Logical Structure of the Worldor Aufbau. Michael Friedman and Alan Richardson haveinitiated much of this debate. They claim that the Aufbauis best understood as a work that is firmly grounded inneo-Kantian philosophy. They have made these claims in oppositionto Quine and Goodman's ``received view'' of the Aufbau. Thereceived view sees the Aufbau as an attempt to carry out indetail Russell's external world program. I argue (...) that both sidesof this debate have made errors in their interpretation ofRussell. These errors have led these interpreters to misunderstandthe connection between Russell's project and Carnap's project.Russell in fact exerted a crucial influence on Carnap in the1920s. This influence is complicated, however, due to the factthat Russell and Carnap disagreed on many philosophical issues. Iconclude that interpretations of the Aufbau that ignoreRussell's influence are incomplete. (shrink)

In this paper I will show why Carnap’s and Quine’s sympathy for the extensionality thesis can be considered equivalent to their concern with clear logical criteria for the manipulation—that is, identification and permutation—of empirical linguistic terms and also why Carnap renounced to the extensionality thesis in the late 1930s. Quine’s inclination to see extensionality as an avoidance of semantic confusion triggered his profound admiration for Carnap’s early works, which are very much of an extensionalist nature. But Quine realizes, as early (...) as the 1930s, that Carnap does not have the same resistance to admitting intensional objects. Already in the Aufbau (1928), Carnap’s phenomenalist and structuralist approach to knowledge, and his pragmatic approach to language systems, leads to the conclusion that the self-psyche and others’ psyche are not something, in principle, inaccessible to knowledge, and, therefore, that intensional—including intentional—objects could, in principle, be scientific objects. In addition to the historical development of semantics—which influenced Carnap—there are two fundamental reasons for Carnap’s increasing tolerance of intensional terminology and analysis in the philosophy of language. In the first place, Carnap thinks it possible to maintain a discourse on intensions without this leading to an ontological commitment to abstract intensional entities. Second, the behaviourist criteria for the identification of intensions that he offered demonstrates that he believed it possible to meet clear identification criteria for intensions. I will show why Carnap disagrees on these two points, in his semantic period, with Quine. (shrink)

This chapter contains sections titled: Introduction Carnap's Logical Positivism Quine's Naturalism The External/Internal Distinction and the Analytic/Synthetic Distinction The Indeterminacy of Translation Quine's Conception of Philosophy I: Metaphysics Quine's Conception of Philosophy II: Ontology Quine's Influence References.

Quine famously holds that "philosophy is continuous with natural science". In order to find out what exactly the point of this claim is, I take up one of his preferred phrases and trace it through his writings, i.e., the phrase "Science itself teaches that …". Unlike Wittgenstein, Quine did not take much interest in determining what might be distinctive of philosophical investigations, or of the philosophical part of scientific investigations. I find this indifference regrettable, and I take a fresh look (...) at Quine's metaphilosophy, trying to defuse his avowed naturalism by illustrating how little influence his naturalistic rhetoric has on the way he actually does philosophy. (shrink)

This article examines what I take to be some of the wrong turns and false dilemmas that analytic philosophy has run into since Quine's well-known attack on the two 'last dogmas' of old-style Logical Empiricism. In particular it traces the consequences of Quine's argument for a thoroughly naturalized epistemology, one that would view philosophy of science as 'all the philosophy we need', and that defines 'philosophy of science' in narrowly physicalist terms. I contend that this amounts to a (...) third residual dogma of empiricism and that its effect has been chiefly to restrict the range of post-Quinean debate by setting an agenda which preemptively excludes all interest in the wider (i.e., critical and normative) dimensions of philosophic enquiry. Its influence can be seen in various responses to Quine, among them those of Donald Davidson and Richard Rorty, both of whom adopt a similar, reductively physicalist approach to issues of meaning, knowledge and truth. Where Davidson takes issue with other Quinean doctrines such as framework-relativism and radical meaning-variance, Rorty pushes those doctrines right through to a wholesale relativist (or 'textualist') position according to which interpretation is completely unconstrained by the mere fact of a causal 'correspondence' between beliefs and reality. What they both share — and what thus lays Davidson open to a revisionist reading in Rorty's favoured style — is this Quine-derived notion that beliefs can be explained in terms of a reflex stimulus-response psychology that finds no room for normative issues of epistemological warrant or justification. For it will then seem plausible for Rorty to claim that any 'beliefs' acquired by such a rudimentary mechanism are compatible with pretty much any higher-level theory or description that one cares to place upon them. My article goes on to criticize Rorty's most extreme statement of the case — in his essay 'Texts and Lumps' — and (more constructively) to suggest some ways forward from this post-empiricist predicament.

Ranging from Joseph Bellamy to Hilary Putnam, and from early New England Divinity Schools to contemporary university philosophy departments, historian Bruce Kuklick recounts the story of the growth of philosophical thinking in the United States. Readers will explore the thought of early American philosphers such as Jonathan Edwards and John Witherspoon and will see how the political ideas of Benjamin Franklin, Thomas Paine and Thomas Jefferson influenced philosophy in colonial America. Kuklick discusses The Transcendental Club (members Henry David Thoreau, Ralph (...) Waldo Emerson) and describes the rise of pragmatism centered on Metaphysical Club of Cambridge (and members William James, Oliver Wendell Holmes, and Charles Peirce). He examines the profound impact Darwinism had on American philosophy and looks at Idealists such as the Kantian Josiah Royce and the Hegelian John Dewey. The book shows how, in the twentieth century, the Nazi conquest of Europe unleashed a flood of European intellectuals onto these shores, including such major thinkers as Theodore Adorno, Erich Fromm, Rudolph Carnap, and Alfred Tarski. Finally, Kuklick examines the contributions of such contemporary philosophers as Sidney Hook and Willard Quine and such books as John Rawl's A Theory of Justice and Herbert Marcuse's One Dimensional Man. Kuklick pulls no punches in portraying the state of American philosophy today and its contested role in the intellectual life of the nation and the world. The range of philosophical thought in our nation's history has been great, from Edwards's Religious Affections to Kuhn's The Structure of Scientific Revolutions, and Bruce Kuklick has captured it all in a book that blends intricate details with sweeping vision.

This book provides an in-depth examination of C.I. Lewis's conceptual pragmatism and its influence on Quine's developing views in epistemology. The author shows how Quine's engagement with problems presented by Lewis, such as analyticity and the empirical given, contribute to the development of his conception of naturalized epistemology.

Quine was one of the foremost philosophers of the Twentieth century. In this outstanding overview of Quine's philosophy, Peter Hylton shows why Quine is so important and how his philosophical naturalism has been so influential within analytic philosophy. Beginning with an overview of Quine's philosophical background in logic and mathematics and the role of Rudolf Carnap's influence on Quine's thought, he goes on to discuss Quine's famous analytic-synthetic distinction and his arguments concerning the nature of (...) the a priori. He also discusses Quine's philosophy of language and epistemology, his celebrated theory of the indeterminacy of translation and his broader views of ontology and modality. This book is essential reading for anyone interested in Quine, twentieth century philosophy and the philosophy of language. (shrink)

Quine’s references to his “pragmatism” have often been seen as indicating a possible link to the American pragmatism of Peirce, James, and Dewey. In Quine, Conceptual Pragmatism, and the Analytic-Synthetic Distinction, I argue that the influence of pragmatism on Quine’s philosophy is more accurately traced to C.I. Lewis’s conceptual pragmatism. Quine’s epistemology shares many affinities with Lewis’s view, which depicts knowledge as a conceptual system pragmatically revised in light of future experience. This claim is defended through an examination of (...) several key episodes in Quine’s philosophical development, including his graduate work for Lewis, critical transition in the 1940s, midcentury criticisms of analyticity, and later turn to naturalized epistemology. This historical account highlights an underappreciated element of the epistemological background to Quine’s criticism of the analytic–synthetic distinction. It is further argued that Lewis’s view provides the central epistemological framework for understanding the form and content of Quine’s later naturalized epistemology. (shrink)

Quine is one of the most influential of contemporary philosophers, whose work has ranged broadly across a great number of topics and issues in a career spanning some fifty years. In this collection a group of distinguished philosophers offer a sustained critical evaluation of the full range of Quine's writings. Amongst the topics addressed are interpretation, epistemology, ontology, modality, and mathematical truth. This collection will certainly influence all future discussion of Quine. The contributors include: George Boolos, H-N. Castaneda, (...) Donald Davidson, Umberto Eco, Dagfinn Follesdal, James Higginbotham, Charles Parsons, Hilary Putnam, Barry Stroud, and Bas van Fraassen. However, Quine is given the last word, responding to the essays in the final contribution. (shrink)

_Real Essentialism_ presents a comprehensive defence of neo-Aristotelian essentialism. Do objects have essences? Must they be the kinds of things they are in spite of the changes they undergo? Can we know what things are really like – can we define and classify reality? Many, if not most, philosophers doubt this, influenced by centuries of empiricism, and by the anti-essentialism of Wittgenstein, Quine, Popper, and other thinkers. _Real Essentialism_ reinvigorates the tradition of realist, essentialist metaphysics, defending the reality and knowability (...) of essence, the possibility of objective, immutable definition, and its relevance to contemporary scientific and metaphysical issues such as whether essence transcends physics and chemistry, the essence of life, the nature of biological species, and the nature of the person.

The Duhem-Quine Thesis is the claim that it is impossible to test a scientific hypothesis in isolation because any empirical test requires assuming the truth of one or more auxiliary hypotheses. This is taken by many philosophers, and is assumed here, to support the further thesis that theory choice is underdetermined by empirical evidence. This inquiry is focused strictly on the axiological commitments engendered in solutions to underdetermination, specifically those of Pierre Duhem and W. V. Quine. Duhem resolves underdetermination by (...) appealing to a cluster of virtues called 'good sense', and it has recently been argued by Stump (Stud Hist Philos Biol Biomed Sei, 18(1):149-159,2007) that good sense is a form of virtue epistemology. This paper considers whether Quine, who's philosophy is heavily influenced by the very thesis that led Duhem to the virtues, is also led to a virtue epistemology in the face of underdetermination. Various sources of Quinian epistemic normativity are considered, and it is argued that, in conjunction with other normative commitments, Quine's sectarian solution to underdetermination amounts to a skills based virtue epistemology. The paper also sketches formal features of the novel form of virtue epistemology common to Duhem and Quine that challenges the adequacy of epistemic value truth-monism and blocks any imperialist naturalization of virtue epistemology, as the epistemic virtues are essential to the success of the sciences themselves.

Quine e Tarski sul nominalismo - Quine and Tarski were kindred philosophical spirits. They rejected the analytic/synthetic distinction and shared a strong distaste for modal notions. Moreover, they both had nominalistic leanings. In this article I trace the nominalistic engagement of these two giants of contemporary analytic philosophy. Using recently discovered material from the Quine archive at Harvard, I begin by describing Quine’s engagement with nominalism up to 1940. I then summarize the impact of the 1940-1941 discussions on nominalism between (...) Carnap, Quine and Tarski and mention their influence on Goodman. The third part of the article deals with Quine’s allegiance to nominalism and his subsequent reluctant acceptance of Platonism. The fourth part focuses on Tarski’s defence of nominalism in Amersfoort in 1953. In the conclusion, Quine’s and Tarski’s approaches to nominalism are compared with some contemporary nominalistic programs. (shrink)

The relationship between Rawls’s theory of justice and Quine’s philosophy constitute an almost entirely new topic of discussion. The analysis undertaken in this article aims to show that some fundamental epistemological traits of Rawls’s theory of justice may be causally explained by referring to Quine’s influence on him. Rawls’s assumptions, methods of theory-building and evaluation criteria are addressed and a close nexus between the methods of ethics and natural science is made explicit. In the light of the historical and (...) epistemological analysis presented in this article it may be argued that Rawls’s theory of justice as fairness satisfies scientific requirements of evidence and objectivity within the sphere of ethics to the extent it is constructed and justified in accordance to Quine’s epistemology.

Although Łukasiewicz and Quine do not share many common views, they agreed on one important point in the 1950s: they both denied the distinction between empirical and a priori sciences. This agreement might be surprising as this denial was rather controversial at that time. This paper focuses on Quine’s and Łukasiewicz’s denials of the distinction between empirical and a priori sciences, and proposes three possible answers to the question of why both formulated the same conclusion at a similar time. Firstly, (...) it discusses Quine’s possible influence on Łukasiewicz as Łukasiewicz agreed with Quine’s criticism of modality at that time. Secondly, it considers the possibility that Quine was affected by Łukasiewicz via his debates with Łukasiewicz’s student, Tarski. Lastly, it takes into account the possibility that both philosophers were inspired by an external source, namely the rise of quantum mechanics. (shrink)

Most commentators have overlooked the impact of Russell on Quine, focusing instead on the influence of Carnap. In what follows, I will argue that the early Quine’s engagement with Russell’s logicism was a crucial stage in the development of his philosophy. More specifically, we can see Quine’s naturalism as developing out of a certain strand of Russell’s thought concerning scientific philosophy. In addition to giving us a better sense of the origins of Quine’s philosophy, this reading also shows how (...) his early work, focusing mostly on technical areas of logic, is deeply related to his later and more famous philosophical views. In particular, his reworking of Principia Mathematica can be understood as the technical working-out of his view that the purpose of philosophy is the clarification our conceptual scheme. (shrink)

Robert Sinclair’s *Quine, Conceptual Pragmatism, and the Analytic-Synthetic Distinction* persuasively argues that Quine’s epistemology was deeply influenced by C. I. Lewis’s pragmatism. Sinclair’s account raises the question why Quine himself frequently downplayed Lewis’s influence. Looking back, Quine has always said that Rudolf Carnap was his “greatest teacher” and that his 1933 meeting with the German philosopher was his “first experience of sustained intellectual engagement with anyone of an older generation” (1970, 41; 1985, 97-8, my emphasis). Quine’s autobiographies contain only (...) a handful of biographical references to Lewis and he regularly soft-pedaled the latter’s influence in private correspondence. In this note, I discuss some archival evidence that helps us better understand Quine’s reluctance to acknowledge Lewis’s influence. I contextualize the relation between Lewis and Quine and argue that the latter viewed his teacher as a retrograde force in modern epistemology, impeding the more rigorous approach that Carnap had been developing in Europe. Next, I briefly discuss Lewis’s contribution to the development of scientific philosophy in the United States and argue that Quine underestimated his teacher’s role in this process. In doing so, I hope to show that Quine’s zealous commitment to Carnap’s approach negatively affected his assessment of Lewis’s influence, thereby supplementing Sinclair’s praiseworthy reconstruction with an explanation of why Quine himself underestimated Lewis’s role.

As a survey included in an issue devoted to W.V. Quine this article contains a list of sixteen distinctively Quinean theses and a brief discussion of the influence of several of them on contemporary philosophy.

Many who explicitly reject some of his more controversial doctrines may not have worked out the (...) interconnections of theses on the list and so can still be said to do philosophy in the manner of, or "after," Quine.

Quine’s classical classic interpretation succinctly characterized characterizes Carnap’s Aufbau as an attempt “to account for the external world as a logical construct of sense-data....” Consequently, “Russell” was characterized as the most important influence on the Aufbau. Those times have passed. Formulating a comprehensive and balanced interpretation of the Aufbau has turned out to be a difficult task and one that must take into account several disjointed sources. My thesis is that the core of the Aufbau rested on a problem (...) that had haunted German philosophy since the end of the 19th century. In terms fashionable at the time, this problem may be expressed as the polarity between Leben and Geist that characterized German philosophy during the years of the Weimar Republic. At that time, many philosophers, including Cassirer, Rickert and Vaihinger, were engaged in overcoming this polarity. As I will show, Carnap’s Aufbau joined the ranks of these projects. This suggests that Lebensphilosophie and Rickert’s System der Philosophie exerted a strong influence on Carnap’s projects, an influence that is particularly conspicuous in his unpublished manuscript Vom Chaos zur Wirklichkeit. Carnap himself asserted that this manuscript could be considered “the germ of the constitution theory” of the Aufbau. Reading Chaos also reveals another strong but neglected influence on the Aufbau, namely a specific version of neutral monism put forward by the philosopher and psychologist Theodor Ziehen before World War I. Ziehen’s work contributed much to the invention of the constitutional method of quasi-analysis. -/-. (shrink)

Abstract At the time of The Logical Syntax of Language (Syntax), Quine was, in his own words, a disciple of Carnap’s who read this work page by page as it issued from Ina Carnap’s typewriter. The present paper will show that there were serious problems with how Syntax dealt with ontological claims. These problems were especially pronounced when Carnap attempted to deal with higher order quantification. Carnap, at the time, viewed all talk of reference as being part of the misleading (...) material mode of speech, and as such dismissed, rather than addressed, ontological problems. Central to the analysis in the present paper is the concept of an explication, which was seen by both Carnap and Quine as being of great philosophical importance. It will be shown that the concept of explication played a significant role in how each formulated their mature position on ontology. Both these final positions on ontology can also be seen as a evolving in reaction to Carnap’s flawed handling of ontological matters at the time of Syntax. Carnap, influenced by Tarski’s work on semantics, comes to believe that the concept of reference can be given an acceptable explication, and that by doing so we can see reference to abstract objects as unobjectionable. As a result, Carnap develops a position very different from the one presented in Syntax. Quine strongly rejected the instrumentalism of Syntax, and sought to give an explication of ontological questions that was language independent. This paper closes with a discussion of each’s understanding of the other’s position. (shrink)

I argue that the real puzzle about Richard Rorty’s intellectual development is not why he gave up on ‘analytic’ philosophy-he had never been much committed to that research agenda, even before it became moribund-but why, beginning with Philosophy and the Mirror of Nature (PMN), he gave up on the central concerns of philosophy going back to antiquity. In addition to Rorty’s published works, I draw on biographical information about Rorty’s undergraduate and graduate education to support this assessment, and contrast his (...) rejection of philosophy with Nietzsche’s. Many contemporary philosophers influenced by Quine’s attack on the analytic-synthetic distinction and Sellars’ attack on ‘the Myth of the Given’ (the two argumentative linchpins of PMN) did not abandon philosophical questions about truth, knowledge, and mind, they just concluded those questions needed to be naturalized, to be answered in conjunction with the empirical sciences. Why didn’t Rorty go this route? The paper concludes with some interesting anecdotes about Rorty that invite speculative explanations. (shrink)

Twenty-first century critics frequently misread Quinean ontological commitment as a toothless doctrine of anti-metaphysical pragmatism. Janssen-Lauret's historical investigations reveal that they misinterpret the influence of Quine's naturalism. His naturalistic view of philosophy as continuous with science informs a much more interesting conception of ontological commitments as generated by indispensable explanatory roles. But Janssen-Lauret uncovers a previously undetected weakness in Quine's meta-ontology. Careful examination of his debate with another naturalistic nominalist, Ruth Barcan Marcus, reveals that his holism leaves (...) him blind to her acquaintance-based ontological commitment via proper names. Janssen-Lauret examines some crucial misunderstandings between Barcan Marcus and Quine, centring on their wildly different interpretations of proper names, quantification and identity, and argues that these are motivated by their diametrically opposed positions on epistemology.

A response to Graham Stevens’s response to Lugg, ‘Russell as a Precursor of Quine’ (Bertrand Russell Society Quarterly, nos. 128-129, pp. 9-21). Stevens challenges the argument of this paper that from 1912, if not earlier, Russell was “a naturalistically-minded epistemologist in the Quinean mould”. He maintains that to the contrary “Russell cannot be accurately characterized as an empiricist” and “Russell’s greatest influence on Quine’s naturalistic project did not stem from his epistemology but from his semantics”. In the present note (...) it is argued Stevens overlooks that Russell is in the empiricist camp as well as the naturalist camp and the empiricist elements of Russell’s philosophy are secondary to his naturalism.

I want to analyse the Quine-Carnap discussion on analyticity with regard to logical, mathematical and set-theoretical statements. In recent years, the renewed interest in Carnap’s work has shed a new light on the analytic-synthetic debate. If one fully appreciates Carnap’s conventionalism, one sees that there was not a metaphysical debate on whether there is an analytic-synthetic distinction, but rather a controversy on the expedience of drawing such a distinction. However, on this view, there can be no longer a single analytic-synthetic (...) distinction, because several kinds of statements could be regarded as analytic (L-determinate). L-equivalence between extra-logical linguistic predicates has already been heavily debated. The recent consensus states that Quine’s rejection of this analytic-synthetic is pragmatically grounded in his linguistic behaviorism. However, Carnap’s logical frameworks also contain other kinds of statements, and it is worthwhile to compare both Quine and Carnap’s grounds for considering these statements as analytic or not analytic. First, I will discuss logical statements. I will argue that Quine draws a very sharp distinction between first order logic and set theory, which should be regarded as a (pragmatic) analytic-synthetic distinction (as Quine admits in an interview, see Theoria, 40, 1994, p. 199). In fact, Quine’s major worry is whether identity statements are analytic. Second, I will discuss mathematical statements. In Carnap’s Foundations of Logic and Mathematics, it is clear that mathematical statements are analytic. For Quine, all mathematical statements are reducible to set-theoretical statements. Third, I discuss the analyticity of set-theoretical statements. For Quine, the membership predicate should be regarded as an interpreted extra-logical predicate. Quine’s work in set theory and his later philosophy of set theory naturally lead to the view that set-theoretical statements cannot be analytic. A major complication for the Quine-Carnap comparison is that Carnap has no elaborate reflections on set theory, while the influence of set theory on Quine’s views can hardly be underestimated. I conclude with some lessons for the contemporary debate on analyticity. (shrink)

Tarski has exerted enormous influence not only on the development of mathematical logic, but on twentieth-century philosophy and philosophical analysis. This influence has been twofold, with the two components pulling in a sense in opposite directions. A comparison with the influence of the Vienna Circle provides an instructive vantage point in viewing Tarski’s influence. On the one hand, Tarski has provided powerful tools for logical analysis in philosophy. His first and most important contribution was to show (...) that — and how — the crucial semantical concept of truth can be defined for various formal languages. They include the most central types of language used and studied by twentieth century logicians and philosophers. The subsequent work by Tarski and his school in creating contemporary model theory in its narrow sense as a branch of technical logic has likewise enriched tremendously the conceptual arsenal of philosophers. The extent and depth of Tarski’s influence is in fact easily underestimated. In comparison, Carnap’s well-known books in logical syntax and logical semantics did not in the same way contribute to the logical techniques that philosophers might find useful. A large part of Tarski’s influence lies in facilitating a switch of emphasis from purely syntactical to model-theoretical, semantical methods. It was Gödel’s and Tarski’s early work that forced logicians and philosophers for the first time to take seriously the distinction between semantical and syntactical concepts and methods. The general theoretical implications of the distinction were not realized at once. In the light of hindsight, it is for instance quite striking that Tarski still in his classical monograph repeatedly assimilates to each other the task of defining truth for some part of mathematics or logic and axiomatizing its truths in a sense that involves explicit syntactical rules of inference. It was nevertheless Tarski more than anyone else who began to develop and exploit systematically model-theoretical concepts in logical theory. In comparison, Gödel never developed systematically the model-theoretical aspects of logic. Others, for instance Quine, stubbornly remained within the syntactical tradition. Carnap, who did switch his attention from the syntactical to a semantical approach, was not powerful enough a logician to create a sufficiently rich store of model-theoretical techniques and ideas to be equally helpful in philosophical analysis. In contrast, several major developments in analytic philosophy have had their starting points in Tarski’s ideas. Well-known cases in point are Davidson’s truth-conditional semantics and the possible worlds semantics developed by Tarski’s favorite former student Richard Montague. (shrink)

Poincaré’s conventionalism has thoroughly transformed both the philosophy of science and the philosophy of mathematics. In the former it gave rise to new insights into the complexities of scientific method, in the latter to a new account of the nature of (so-called) necessary truth. Not only proponents of conventionalism, such as the logical positivists, were influenced by Poincaré, but also outspoken critics of conventionalism, such as Quine, Putnam, and (as I will argue) Wittgenstein, were deeply inspired by conventionalist ideas. Indeed, (...) during the twentieth century, most philosophers of science and mathematics engaged in dialogue with conventionalism. As is often the case with complex ideas, there is no consensus about the meaning of conventionalism in general and Poincaré’s original version of it in particular. Nonetheless, notions such as underdetermination (of theory), empirical equivalence (of incompatible theories), implicit definition, holism, and conceptual relativity, all of which can be linked to Poincaré’s writings, have become central to philosophy. In tracing the flow of Poincaré’s ideas through the philosophical space of the twentieth century, this article emphasizes not only the stimulus provided by his actual views but also the effects of misreading and unjustified appropriation.

An odd dissensus between confident metaphysicians and neopragmatist antimetaphysicians pervades early twenty-first century analytic philosophy. Each faction is convinced their side has won the day, but both are mistaken about the philosophical legacy of the twentieth century. More historical awareness is needed to overcome the current dissensus. Lewis and his possible-world system are lionised by metaphysicians; Quine’s pragmatist scruples about heavy-duty metaphysics inspire antimetaphysicians. But Lewis developed his system under the influence of his teacher Quine, inheriting from him his (...) empiricism, his physicalism, his metaontology, and, I will show in this paper, also his Humeanism. Using published as well as never-before-seen unpublished sources, I will make apparent that both heavy-duty metaphysicians and neopragmatist antimetaphysicians are wrong about the roles Quine and Lewis played in the development of twentieth-century philosophy. The two are much more alike than is commonly supposed, and Quine much more instrumental to the pedigree of current metaphysics. (shrink)

In this lively look at current debates in American philosophy, leading philosophers talk candidly about the changing character of their discipline. In the spirit of Emerson's _The American Scholar_, this book explores the identity of the American philosopher. Through informal conversations, the participants discuss the rise of post-analytic philosophy in America and its relations to European thought and to the American pragmatist tradition. They comment on their own intellectual development as well as each others' work, charting the course of American (...) philosophy over the past few decades. Giovanna Borradori, in her substantial introduction, explains the history of the analytic movement in America and the home-grown reaction against it. In the late nineteenth and early twentieth centuries, American philosophy was a socially engaged interdisciplinary enterprise. In transcendentalism and pragmatism, then the dominant currents in American thought, philosophy was connected to history, psychology, and public issues. But in the 1930s, the imported European movement of logical positivism redefined philosophical discourse in terms of mathematical logic and theory of language. Under the influence of this analytic view, American philosophy became a professionalized discipline, divorced from public debate and intellectual history and antagonistic to the other, more humanistic tradition of continental thought. _The American Philosopher_ explores the opposition between analytic and continental thought and shows how recent American work has begun to bridge the gap between the two traditions. Through a reexamination of pragmatism, and through an attempt to understand philosophy in a more hermeneutical way, the participants narrow the distance between America's distinctly scientific philosophy and Europe's more literary approach. Moving beyond classical analytic philosophy, the participants confront each other on a number of topics. The logico-linguistic orientations of Quine and Davidson come up against the more discursive, interdisciplinary agendas of Rorty, Putnam, and Cavell. Nozick's theory of pluralist anarchism goes face-to-face with the aesthetic neo-foundationalism of Danto. And Kuhn's hypothesis of paradigm shifts is measured against MacIntyre's ethics of "virtues." Borradori's conversations offer an unconventional portrait of the way philosophers think about their work; scholars and students will not be its only beneficiaries, so will everyone who wonders about the current state of American philosophy.

Poincaré’s conventionalism has thoroughly transformed both the philosophy of science and the philosophy of mathematics. Not only proponents of conventionalism, such as the logical positivists, were influenced by Poincaré, but also outspoken critics of conventionalism, such as Quine and Putnam, were inspired by his daring position. Indeed, during the twentieth century, most philosophers of mathematics and of science engaged in dialogue with conventionalism. As is often the case with such complex clusters of ideas, there is no consensus about the meaning (...) of conventionalism in general, and Poincaré’s original version of it, in particular. Nonetheless, notions such as the under-determination, empirical equivalence, implicit definition, holism and conceptual relativity, all of which can be linked to Poincare's writings have become central to philosophy. This essay explores the impact of some of these notions on twentieth century philosophy of science. In addition to inspiration based on Poincare's actual views, it emphasizes directions based on misreading and unjustified appropriations of Poincaré. (shrink)

The revival of the philosophy of mathematics in the 60s following its post-1931 slump left us with two conflicting positions on arithmetic’s ontological relationship to set theory. W.V. Quine’s view, presented in 'Word and Object' (1960), was that numbers are sets. The opposing view was advanced in another milestone of twentieth-century philosophy of mathematics, Paul Benacerraf’s 'What Numbers Could Not Be' (1965): one of the things numbers could not be, it explained, was sets; the other thing numbers could not be, (...) even more dramatically, was objects. Curiously, although Benacerraf’s article appeared in the heyday of Quine’s influence, it declined to engage the Quinean position squarely, even seemed to think it was not its business to do so. Despite that, in my experience, most philosophers believe that Benacerraf’s article put paid to the reductionist view that numbers are sets (though perhaps not the view that numbers are objects). My chapter will attempt to overturn this orthodoxy. (shrink)

In this lively look at current debates in American philosophy, leading philosophers talk candidly about the changing character of their discipline. In the spirit of Emerson's The American Scholar , this book explores the identity of the American philosopher. Through informal conversations, the participants discuss the rise of post-analytic philosophy in America and its relations to European thought and to the American pragmatist tradition. They comment on their own intellectual development as well as each others' work, charting the course of (...) American philosophy over the past few decades. Giovanna Borradori, in her substantial introduction, explains the history of the analytic movement in America and the home-grown reaction against it. In the late nineteenth and early twentieth centuries, American philosophy was a socially engaged interdisciplinary enterprise. In transcendentalism and pragmatism, then the dominant currents in American thought, philosophy was connected to history, psychology, and public issues. But in the 1930s, the imported European movement of logical positivism redefined philosophical discourse in terms of mathematical logic and theory of language. Under the influence of this analytic view, American philosophy became a professionalized discipline, divorced from public debate and intellectual history and antagonistic to the other, more humanistic tradition of continental thought. The American Philosopher explores the opposition between analytic and continental thought and shows how recent American work has begun to bridge the gap between the two traditions. Through a reexamination of pragmatism, and through an attempt to understand philosophy in a more hermeneutical way, the participants narrow the distance between America's distinctly scientific philosophy and Europe's more literary approach. Moving beyond classical analytic philosophy, the participants confront each other on a number of topics. The logico-linguistic orientations of Quine and Davidson come up against the more discursive, interdisciplinary agendas of Rorty, Putnam, and Cavell. Nozick's theory of pluralist anarchism goes face-to-face with the aesthetic neo-foundationalism of Danto. And Kuhn's hypothesis of paradigm shifts is measured against MacIntyre's ethics of "virtues." Borradori's conversations offer an unconventional portrait of the way philosophers think about their work scholars and students will not be its only beneficiaries, so will everyone who wonders about the current state of American philosophy.

Under the influence of Quine’s famous manifesto, many philosophers have thought that logical theories are scientific theories that can be ‘adopted’ and tested as scientific theories. Here we argue that this idea is untenable. We discuss it with special reference to Putnam’s proposal to ‘adopt’ a particular non-classical logic to solve the foundational problems of quantum mechanics in his famous paper ‘Is Logic Empirical?’ (1968), which we argue was not really coherent.

W.V.O.Quine’s doctrine of referential inscrutability (RI) is the thesis that, first, linguistic reference must always be determined relative to an interpretation of the discourse and, second, that the empirical evidence always underdetermines our choice of interpretation--at least in principle. Although this thesis is a central result of Quine’s theory of language, it was long unclear just how much force RI actually carried. At best, Quine’s discussions provided localized examples of RI (e.g., ‘gavagai’), supplemented merely by arguments for the (in principle) (...) constructability of more general referentially divergent manuals. In defense of Quine, Gerald Massey provides a method for generating large-scale referentially divergent manuals for a complex language. I argue that, while Massey’s rival manuals do meet Quine’s translational criteria, they are demonstrably inferior to their commonsensical “homophonic” competitor. This result provides a clear indication of seminal deficiencies in Quine’s behaviorial approach to the theory of language. Next I argue that Quine’s acceptance of standard assumptions about the nature of perception strongly influences the shape of his semantical theory. Finally, I suggest how an alternative to the standard account of perception might provide grounds for a more adequate understanding of language. (shrink)

Guided by key insights of the four great philosophers mentioned in the title, here, in review of and expanding on our earlier work (Burchard, 2005, 2011), we present an exposition of the role played by language, & in the broader sense, λογοζ, the Logos, in how the CNS, the brain, is running the human being. Evolution by neural Darwinism has been forcing the linguistic nature of mind, enabling it to overcome & exploit the cognitive gap between an animal and its (...) world by recognizing environmental structures. Our work was greatly influenced by Heidegger’s lecture notes on metaphysics (Heidegger, 1935). We found agreement with recent progress in neuroscience, but also mathematical foundations of language theory, equating Logos with the mathematical concept of structure. The mystery of perception across the gap is analyzed as radiation and molecules impinging on sensory neurons that carry linguistic information about gross environmental structures, and only remotely about the physical reality of elementary particles. The most important logical brain function is Ego or Self, guiding the workings of the brain as a logos machine. Ego or Self operates from neurons in frontopolar cortex with global receptive fields. The logos machine can function only by availing itself of global context, its internally stored noumenal cosmos NK, and the categorical-conceptual apparatus CCA, updated continually through the neural default mode network (Raichle, 2005). In the Transcendental Deduction, Immanuel Kant discovered that Ego or Self is responsible for conscious control in perception relying on concepts & categories for a fitting percept to be incorporated intoNK. The entire CNS runs as a “movie-in-the-brain” (Parvizi & Damasio, 2001), at peak speed processing simultaneously in a series of cortical centers a stack of up to twelve frames in gamma rhythm of 25 ms intervals. We equate global context, or NK, with our human world, Heidegger’s Dasein being-in-the-world, and are able to demonstrate that the great philosopher in EM parallels neuro-science concerning the human mind.

This paper discusses the impact of East Asian philosophical ideas on the origins and development of martial arts. The article argues that the ideas of Daoist philosophy were developed into ‘soft styles’ or ‘internal schools’ that are based on the doctrine of ‘wuwei’ (action through non-action, effortless action) which follows the path of Yin. These styles are in opposition to ‘external’ or ‘hard styles’ of martial arts that follow the path of Yang. Daoist philosophy of ‘ziran’ (naturalness, spontaneity) influenced ‘animal’ (...) or ‘imitation styles’ and the paradigm of natural, unplanned, and unforced combat movements. The influence of Buddhism on martial arts is found in techniques of mental tranquillity training for the extreme conditions of combat. The work also shows the significance of Confucianism for the formation of a code of honor for warriors, which includes the ethics of duty and respect. (shrink)

A compact, coherent introduction to the study of rational belief, this text provides points of entry to such areas of philosophy as theory of knowledge, methodology of science, and philosophy of language. The book is accessible to all undergraduates and presupposes no philosophical training.
