Alexander George has put forward a novel interpretation of the Quine-Carnap debate over analyticity. George argues that Carnap's claim that there exists an analytic-synthetic distinction was held by Carnap to be empty of empirical consequences. As a result, Carnap understood his position to be empirically indistinguishable from Quine's. Although George defends his interpretation only briefly, I show that it withstands further examination and ought to be accepted. The consequences of accepting it undermine a (...) common understanding of Quine's criticism of Carnap, and I argue that it is difficult to find a perspective from which Quine can criticize Carnap in a non-question-begging way.

With metaphysical philosophy gaining prominence in the aftermath of the Quine-Carnap debate, not only has it become assumed that the Quinean critique leaves ontological pluralism behind as an untenable approach, but also that the same is true of deflationism more generally. Building on Quine’s criticisms against the analytic-synthetic distinction and the notion of quantifier variance, contemporary metaphysicians like van Inwagen and Sider continue to argue for the untenability of deflationary approaches to metaontology. In this paper I (...) will argue that Quine’s criticisms do not provide sufficient grounds for revitalizing metaphysics, as the aforementioned metaphysicians conceive them as doing, and that they also don’t eliminate all hope for Carnapian pluralism. Furthermore, Carnap’s initial position may even yield the most promising route for the pluralistically inclined. Moreover, pluralism is often conceived as being equivalent with the narrower notion of quantifier variance, often associated with Hirsch and Putnam. As this notion often is attributed not only to Carnap and other pluralists, but also is taken to be an essential feature of deflationism, explicating how their merits in fact don’t necessarily coincide with those of quantifier variance will clarify matters. I will conclude by noting how neither pluralism nor deflationism is committed to quantifier variance, and thus how arguments against the latter don’t entail a refutation of the former. (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)

In the middle of the twentieth century a dispute erupted between the chief architect of Logical Empiricism, Rudolf Carnap, and Logical Empiricism’s chief reformer, Willard van Orman Quine -- who was attempting to save what he took to be its main insights by recasting them in a more acceptable form. Though both eschewed metaphysics of the traditional apriori sort, and both were intent on making the investigation of science the center of philosophy, they disagreed about how to do (...) so. Part of the disagreement involved the nature of ontological disputes. The central documents in the debate are: (i) Quine’s 1948 article, “On What There Is,” which tells us how to discern ontological.. (shrink)

On a widespread reading, the Carnap-Quine debate about ontology concerns the objectivity and non-triviality of ontological claims. I argue that this view mischaracterizes Carnap’s aims in “Empiricism, Semantics, and Ontology” : Carnap’s fundamental goal is to free up decisions about scientific language from constraints deriving from ontological doctrine. The contention, based on his internal/external distinction, that ontological claims are either meaningless or trivial was Carnap’s means to achieving this more fundamental goal. Setting the record (...) straight on this point brings out three important and often overlooked features of Carnap’s views on ontology. First, the target of Carnap’s critique in ESO is not Quine’s mature views on ontology, as laid out in “On What There Is”. Rather, Carnap is responding to arguments for nominalism that were given by Tarski, Goodman, and Quine in the 1940s. Second, a more general rejection of conservatism in theory choice is essential to Carnap’s aims and is implicit in his fundamental views on language. Third, even if it turns out to be tenable, the i/e distinction is not adequate for Carnap’s aim in ESO. Drawing on his basic conception of scientific language, I will suggest an alternative approach on his behalf. (shrink)

Pour concilier son empirisme avec le fait que les « vérités » logiques et mathématiques semblent indépendantes de ce qui est le cas dans le monde, Carnap repris à son compte, en l’élaborant soigneusement, la thèse développée par Wittgenstein dans son Tractatus, selon laquelle les énoncés logiques et mathématiques ne disent rien du monde : ils sont « analytiques ». Son disciple et ami, Quine, en vint à récuser la notion d’analyticité et le partage entre énoncés analytiques et (...) énoncés synthétiques. Il s’ensuivit, entre les deux hommes, un débat philosophique exemplaire par sa rigueur et son honnêteté intellectuelle. Cet article tente de restituer les grandes lignes de ce débat et d’en dégager les ressorts. (shrink)

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)

Robert Sinclair: Quine on Evidence: Quine's influential “Epistemology Naturalized” is typically read as arguing for the replacement of the “normative” project of traditional epistemology with a psychological description of the causal processes involved in belief acquisition. Recent commentators have rejected this view, arguing that rather than eliminate normative concerns, Quine's proposal seeks to locate them within his scientific conception of epistemology. This chapter examines this debate concerning the normative credentials of Quine's naturalized account of knowledge (...) and its consequences for understanding the role of justification and evidence within his epistemology. It explains how Quine's appeal to psychology should be seen as addressing normative concerns over the evidential connections between theory and observation and further indicates how he addresses issues involving evidence and justification. It concludes by considering some later changes in Quine's epistemology that may be seen as challenging his attempt to address the evidential support of science. (shrink)

Rudolf Carnap and W. V. O Quine have long been seen as key figures of analytic philosophy who are opposed to each other, due in no small part to their famed debate over the analytic/synthetic distinction. This volume of new essays assembles for the first time a number of scholars of the history of analytic philosophy who see Carnap and Quine as figures largely sympathetic to each other in their philosophical views. The essays acknowledge the (...) differences which exist, but through their emphasis on Carnap and Quine's shared assumption about how philosophy should be done-that philosophy should be complementary to and continuous with the natural and mathematical sciences-our understanding of how they diverge is also deepened. This volume reshapes our understanding not only of Carnap and Quine, but of the history of analytic philosophy generally. (shrink)

Carnap's ideal of explication has become a key concept in analytic philosophy and the basis of a method of analysis which may be considered as an alternative to various forms of naturalism, including Quine's conception of a naturalized epistemology.

W. V. Quine’s first philosophical monograph, Word and Object, is widely recognized as one of the most influential books of twentieth century philosophy. Notes, letters, and draft manuscripts at the Quine Archives, however, reveal that Quine was already working on a philosophical book in the early 1940s; a project entitled Sign and Object. In this paper, I examine these and other unpublished documents and show that Sign and Object sheds new light on the evolution of Quine’s (...) ideas. Where “Two Dogmas of Empiricism” is usually considered to be a turning point in Quine’s development, this paper redefines the place of ‘Two Dogmas’ in his oeuvre. Not only does Quine’s book project reveal that his views were already fairly naturalistic in the early 1940s ; Sign and Object also unearths the steps Quine had to take in maturing his perspective; steps that will be traced in the second half of this paper.

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)

A new direction in philosophy Between 1920 and 1940 logical empiricism reset the direction of philosophy of science and much of the rest of Anglo-American philosophy. It began as a relatively organized movement centered on the Vienna Circle, and like-minded philosophers elsewhere, especially in Berlin. As Europe drifted into the Nazi era, several important figures, especially Carnap and Neurath, also found common ground in their liberal politics and radical social agenda. Together, the logical empiricists set out to reform traditional (...) philosophy with a new set of doctrines more firmly grounded in logic and science. Criticism and decline Because of Nazi persecution, most of the European adherents of logical empiricism moved to the United States in the late 1930s. During the 1940s, many of their most cherished tenets became targets of criticism from outsiders as well as from within their own ranks. Philosophers of science in the late 1950s and 1960s rejected logical empiricism and, starting in the 1970s, presented such alternative programs such as scientific realism with evolutionary epistemology. A resurgence of interest During the early 1980s, philosophers and historians of philosophy began to study logical empiricism as an important movement. Unlike their predecessors in the 1960s-for whom the debate over logical empiricism now seems to have been largely motivated by professional politics-these philosopher no longer have to take positions for or against logical empiricism. The result has been a more balanced view of that movement, its achievements, its failures, and its influence. Hard-to-find core writings now available This collection makes available a selection of the most influential and representative writings of the logical empiricists, important contemporary criticisms of their doctrines, their responses, as well as the recent reappraisals.

During the past few decades, a radical shift has occurred in how philosophers conceive of the relation between science and philosophy. A great number of analytic philosophers have adopted what is commonly called a ‘naturalistic’ approach, arguing that their inquiries ought to be in some sense continuous with science. Where early analytic philosophers often relied on a sharp distinction between science and philosophy—the former an empirical discipline concerned with fact, the latter an a priori discipline concerned with meaning—philosophers today largely (...) follow Willard Van Orman Quine (1908-2000) in his seminal rejection of this distinction. -/- This book offers a comprehensive study of Quine’s naturalism. Building on Quine’s published corpus as well as thousands of unpublished letters, notes, lectures, papers, proposals, and annotations from the Quine archives, this book aims to reconstruct both the nature (chapters 2-4) and the development (chapter 5-7) of his naturalism. As such, this book aims to contribute to the rapidly developing historiography of analytic philosophy, and to provide a better, historically informed, understanding of what is philosophically at stake in the contemporary naturalistic turn.

Analytic philosophy is once again in a methodological frame of mind. Nowhere is this more evident than in metaphysics, whose practitioners and historians are actively reflecting on the nature of ontological questions, the status of their answers, and the relevance of contributions both from other areas within philosophy and beyond. Such reflections are hardly new: the debate between Willard van Orman Quine and Rudolf Carnap about how to understand and resolve ontological questions is widely seen as a (...) turning point in twentieth-century analytic philosophy. And indeed, this volume is occasioned by the fact that the deflationary approach to metaphysics advocated by Carnap in that debate is once again attracting considerable interest and support. Eleven original essays by many of today's leading voices in metametaphysics aim to deepen our understanding of Carnap's contributions to metaontology and to explore how this legacy might be mined for insights into the contemporary debate.

Quine’s ‘Two Dogmas of Empiricism’ is generally seen as overturning Carnap’s epistemological picture of mathematics and the sciences. However, I wish to stress how this paper grew out of arguments not having anything to do with large-scale epistemological concerns, but ones originally presented against quantified modal logic. Quine thought he could demonstrate the impossibility of adding anything like ordinary quantification to modal logic, but Barcan Marcus did exactly this. In fact, as I will argue, ‘Two Dogmas ...’ (...) can be seen as growing out of a 1947 paper of Quine’s where Barcan Marcus is the explicit target. Later, in certain exchanges with Quine, Barcan Marcus puts forward and defends a consistent and interesting position on matters of ontology and the philosophy of language. This chapter will examine Barcan Marcus’s role in both the debate over analyticity and the debate on (meta-)ontology. (shrink)

Contemporary analytic philosophy is dominated by metaphilosophical naturalism, the view that philosophy ought to be continuous with science. This naturalistic turn is for a significant part due to the work of W. V. Quine. Yet, the development and the reception of Quine’s naturalism have never been systematically studied. In this paper, I examine Quine’s evolving naturalism as well as the reception of his views. Scrutinizing a large set of unpublished notes, correspondence, drafts, papers, and lectures as well (...) as published responses to Quine’s work, I show how both internal tensions and external criticisms forced him to continuously develop, rebrand, and refine his metaphilosophy before he explicitly decided to label his view ‘naturalism’ in the late 1960s.

This article sketches out the key features of the debate on the analytic-synthetic distinction between phenomenology and logical empiricism, which took place in the early part of the twentieth century. On the one side, the author reconstructs the debate itself from an historical angle; on the other, he gives a theoretical account of the different positions and arguments. In particular, he has three main aims: a) to clarify how, according to Husserl, the analyticsynthetic opposition is to be understood (...) as the form-matter opposition; b) to show how this position has been misunderstood by neo-empiricist philosophers, in particular by Schlick in his paper against the theory of the factual a priori; c) to point out that Husserlian theory anticipates some relevant features in the matter of analyticity (i.e. the distinction between logical analytic and extra-logical analytic truths) which will be made fully explicit only by Carnap and Quine, philosophers of the following generation.

Similarly to other accounts of disease, Christopher Boorse’s Biostatistical Theory (BST) is generally presented and considered as conceptual analysis, that is, as making claims about the meaning of currently used concepts. But conceptual analysis has been convincingly critiqued as relying on problematic assumptions about the existence, meaning, and use of concepts. Because of these problems, accounts of disease and health should be evaluated not as claims about current meaning, I argue, but instead as proposals about how to define and use (...) these terms in the future, a methodology suggested by Quine and Carnap. I begin this article by describing problems with conceptual analysis and advantages of “philosophical explication,” my favored approach. I then describe two attacks on the BST that also question the entire project of defining “disease.” Finally, I defend the BST as a philosophical explication by showing how it could define useful terms for medical science and ethics.

How do we come to know metaphysical truths? How does metaphysical inquiry work? Are metaphysical debates substantial? These are the questions which characterize metametaphysics. This book, the first systematic student introduction dedicated to metametaphysics, discusses the nature of metaphysics - its methodology, epistemology, ontology and our access to metaphysical knowledge. It provides students with a firm grounding in the basics of metametaphysics, covering a broad range of topics in metaontology such as existence, quantification, ontological commitment and ontological realism. Contemporary views (...) are discussed along with those of Quine, Carnap and Meinong. Going beyond the metaontological debate, thorough treatment is given to novel topics in metametaphysics, including grounding, ontological dependence, fundamentality, modal epistemology, intuitions, thought experiments and the relationship between metaphysics and science. The book will be an essential resource for those studying advanced metaphysics, philosophical methodology, metametaphysics, epistemology and the philosophy of science. (shrink)

Following W.V. Quine’s lead, many metaphysicians consider ontology to be concerned primarily with existential questions of the form, “What is there?”. Moreover, if the position advanced by Rudolf Carnap, in his seminal essay, “Empiricism, Semantics, and Ontology ”, is correct, then many of these existential ontological questions ought to be classified as either trivially answerable or as “pseudo-questions”. One may justifiably wonder, however, whether the Quinean and Carnapian perspective on ontology really does justice to many of the most (...) central concerns of this discipline. This chapter argues, by considering a particular ontological dispute between two different kinds of trope theorists, that some of the most interesting and important debates which properly belong to the study of being, whether we call it “metaphysics” or “ ontology ”, do not concern existential questions at all; rather, such disputes in some cases focus on non-existential disagreements over questions of fundamentality.

Nosso artigo irá avaliar a contribuição de uma teoria intensional para projetos de filosofia da ciência. Esperamos explorar o conceito de intensão, que fez parte da polêmica semântica do século XX, para discutir a natureza dos enunciados da ciência e suas diferenças de profundidade. Optamos por dar a seguinte forma à argumentação: almejamos apresentar indícios para a plausibilidade da tese de que as intensões contribuem para marcar diferenças de conteúdo preditivo das proposições. Argumentaremos que essas diferenças falham em ser avaliadas (...) extensionalmente. Sugerimos explorar a diferença entre intensões carnapianas (Carnap 1891-1970) e millianas (Stuart Mill 1806-1873). A linha de contraste será traçada a partir dos problemas para os quais os autores elaboraram seu conceito: as primeiras para ampliar o universo extensional da interpretação com casos possíveis mapeados por um modelo (as quais chamaremos de extensionalidade estendida), e as segundas para resolver problemas de profundidade teórica, entendidos como questões de projeção e predição. A sequência do artigo avalia o desafio de Quine à concepção carnapiana de intensão, e explora a seguinte opção: a de que uma versão profunda (milliana) do conceito de intensão e analiticidade não seria alvo da crítica de Quine. Passamos, por fim, por um exame de possíveis alinhamentos e alianças com o racionalismo crítico recente (David Miller, J. Watkins), para concluir que o universo da filosofia da ciência está aberto a discutir a contribuição de uma noção não-extensional de significação. (shrink)

Recent Carnap scholarship suggests that the received view of the Carnap-Quine analyticity debate is importantly mistaken. It has been suggested that Carnap’s analyticity distinction is immune from Quine’s criticisms. This is either because Quine did not understand Carnap’s use of analytic-ity, or because Quine did not appreciate that, rather than dispelling dog-mas, he was merely offering an alternate framework for philosophy. It has also been suggested that ultimately nothing of substance turns (...) on this dis-pute. I am sympathetic to these reassessments and their rejection of the re-ceived view, but argue that they fail to pay proper attention to Carnap’s metaphysical deflationism. For it is there that Quine’s arguments ultimately make contact with Carnap, undermining his metaphysical deflationism. Moreover, the viability of deflationism is directly related to the viability of Carnap’s view of philosophy as methodologically distinct from science. Hence, Quine’s criticisms make contact with the deepest aspects of Carnap’s views. (shrink)

This is a useful collection of readings for a senior undergraduate or junior-level graduate course on universals. The selections are short, but generally self-contained, and thus accessible to readers unfamiliar with the literature. Most of the great contributors to the debate, from Plato to the early Russell, Husserl, and Heidegger, are well represented, with a good sampling of the medieval discussion in pieces from Abelard, St. Thomas, Duns Scotus, and Ockham. Postwar twentieth-century contributors include Quine, Carnap, Strawson, (...) and David Pears; and the text ends with a helpful bibliography of books and articles for further inquiry. (shrink)

"This book is valuable as expounding in full a theory of meaning that has its roots in the work of Frege and has been of the widest influence....

The book is marked by a genial tolerance. Carnap sees himself as proposing conventions rather than asserting truths. However he provides plenty (...) of matter for argument."-Anthony Quinton, Hibbert Journal. (shrink)

ABSTRACT Analytic philosophy in the mid-twentieth century underwent a major change of direction when a prior consensus in favour of extensionalism and descriptivism made way for approaches using direct reference, the necessity of identity, and modal logic. All three were first defended, in the analytic tradition, by one woman, Ruth Barcan Marcus. But analytic philosophers now tend to credit them to Kripke, or Kripke and Carnap. I argue that seeing Barcan Marcus in her historical context – one dominated by (...) extensionalism and descriptivism – allows us to see how revolutionary she was, in her work and influence on others. I focus on her debate with Quine, who found himself retreating to softened, and more viable, versions of his anti-modal arguments as a result. I make the case that Barcan's formal logic was philosophically well-motivated, connected to her views on reference, and well-matched to her overall views on ontology. Her nominalism led her to reject posits which could not be directly observed and named, such as possibilia. She conceived of modal calculi as facilitating counterfactual discourse about actual existents. I conclude that her contributions ought to be recognized as the first of their kind. Barcan Marcus must be awarded a central place in the canon of analytic philosophy. (shrink)

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)

W. V. Quine is commonly read as holding that there are no analytic truths and no a priori truths. I argue that this is a misreading. Quine’s view is that no sentence is determinately analytic or determinately a priori. I show that my reading is better supported by Quine’s arguments and general remarks about meaning and analyticity. I then briefly reexamine the debate between Quine and Carnap about analyticity, and show that the nature of (...) their disagreement is different than what it is usually thought to be. (shrink)

Rudolf Carnap and W. V. Quine, two of the twentieth century's most important philosophers, corresponded at length—and over a long period of time—on matters personal, professional, and philosophical. Their friendship encompassed issues and disagreements that go to the heart of contemporary philosophic discussions. Carnap was a founder and leader of the logical positivist school. The younger Quine began as his staunch admirer but diverged from him increasingly over questions in the analysis of meaning and the justification (...) of belief. That they remained close, relishing their differences through years of correspondence, shows their stature both as thinkers and as friends. The letters are presented here, in full, for the first time. The substantial introduction by Richard Creath offers a lively overview of Carnap's and Quine's careers and backgrounds, allowing the nonspecialist to see their writings in historical and intellectual perspective. Creath also provides a judicious analysis of the philosophical divide between them, showing how deep the issues cut into the discipline, and how to a large extent they remain unresolved. (shrink)

Inspired by Rudolf Carnap's Der Logische Aufbau Der Welt, David J. Chalmers argues that the world can be constructed from a few basic elements. He develops a scrutability thesis saying that all truths about the world can be derived from basic truths and ideal reasoning. This thesis leads to many philosophical consequences: a broadly Fregean approach to meaning, an internalist approach to the contents of thought, and a reply to W. V. Quine's arguments against the analytic and the (...) a priori. Chalmers also uses scrutability to analyze the unity of science, to defend a conceptual approach to metaphysics, and to mount a structuralist response to skepticism. Based on the 2010 John Locke lectures, Constructing the World opens up debate on central philosophical issues involving language, consciousness, knowledge, and reality.

In this dissertation, I explore the work of Donald Davidson, reveal an inconsistency in it, and resolve that inconsistency in a way that complements a debate in philosophy of science. In Part One, I explicate Davidson's extensional account of meaning; though not defending Davidson from all objections, I nonetheless present his seemingly disparate views as a coherent whole. In Part Two, I explicate Davidson's views on the dualism between conceptual schemes and empirical content, isolating four seemingly different arguments that (...) Davidson makes against the dualism; I demonstrate that, though the arguments fail, each is ultimately meant to rely on his account of meaning. ;In Part Three, I show that Davidson's extensional account of meaning gives rise to the analytic-synthetic distinction, while simultaneously needing to reject it. I then propose a resolution to Davidson's dilemma. Rather than treating interpretation of meaning as continuous with the holistic enterprise of science, as Quine treats translation, one should treat it as conceptually prior to science, as Kant treats epistemology. Nonetheless I recognize four reasons why Davidson himself would reject doing so. I therefore propose a view called 'transcendental semantics', based on Davidson's, that accepts my resolution. Further, transcendental semantics, like Kant's own transcendental idealism, posits a single conceptual scheme; nonetheless Kant's is concerned with Newtonian physics, transcendental semantics' with interpretation. ;Finally, in Part Four, I show how positing such a scheme allows transcendental semantics to complement a promising neo-Carnapian account of theory confirmation in science proposed by Michael Friedman. Scientists are first and foremost interpreters, a fact that allows transcendental semantics to help Friedman establish the possibility of rational continuity through scientific revolutions. In fact, transcendental semantics, by complementing Friedman's project, reunites two of Carnap's own concerns, philosophy of language and philosophy of science. I conclude that philosophy of language without philosophy of science is empty , while philosophy of science without philosophy of language is blind. (shrink)

Quine's well-known ‘Two Dogmas of Empiricism’ (1951) plays a key role in the debate about the analytic-synthetic distinction. Taking to task the ideas of Carnap in particular, Quine shows that logical positivism works with a concept of scientific rationality that is based dogmatically on, among other things, the opposition analytic-synthetic.

Carnap's mature philosophy of science is an attempt to dissolve the scientific realism debate altogether as a philosophical pseudo-question. His argument depends upon a logico-semantic thesis regarding the structure of a scientific theory, and more importantly, a meta-ontological thesis regarding the explication of existence claims. The latter commits Carnap to a distinction between the analytic and the synthetic, which was allegedly refuted by Quine. The contemporary philosophy of science has therefore sought to distance itself from logico-semantic (...) considerations, and has pursued the scientific realism debate as an essentially epistemological thesis. I show however that one of the most prominent positions in this recent debate—van Fraassen's constructive empiricism—not only ends up in very close proximity to Carnap's attempted dissolution, but even provides the resources for extending and refining his programme. Rather than a historical footnote, Carnap's mature philosophy of science offers a live-option in the current debate. (shrink)

During the academic year 1940-1941, several giants of analytic philosophy congregated at Harvard, holding regular private meetings, with Carnap, Tarski, and Quine. Carnap, Tarski, and Quine at Harvard allows the reader to act as a fly on the wall for their conversations. Carnap took detailed notes during his year at Harvard. This book includes both a German transcription of these shorthand notes and an English translation in the appendix section. Carnap’s notes cover a wide (...) range of topics, but surprisingly, the most prominent question is: If the number of physical items in the universe is finite, what form should scientific discourse take? This question is closely connected to an abiding philosophical problem: What is the relationship between the logico-mathematical realm and the material realm? Carnap, Tarski, and Quine’s attempts to answer this question involve issues central to philosophy today.This book focuses on three such issues: nominalism, the unity of science, and analyticity. In short, the book reconstructs the lines of argument represented in these Harvard discussions, discusses their historical significance (especially Quine’s break from Carnap), and relates them when possible to contemporary treatments of these issues.

In this paper I return to the mid-20th-century debate between Quine and Carnap on the status of metaphysics questions with an eye toward advancing contemporary debates about whether naturalists can coherently undertake substantive metaphysical inquiry. Following Huw Price, I take the debate between Quine and Carnap to hinge, in part, on whether human inquiry is functionally unified. However, unlike Price, I suggest that this question is not best understood as a question about the function(s) (...) of descriptive discourse. This goes along with rejecting a “linguistic conception” of the starting point of metaphysical inquiry, which, although shared by Quine and Carnap, Price gives us no good reason to think is mandatory for naturalists. I sketch two reasons naturalists have to reject a particular manifestation of this linguistic conception in Quine’s work—his criterion of ontological commitment. Finally, I show how these reasons can help us identify the grains of truth in some recent critiques of “mainstream metaphysics of mind.”. (shrink)

In recent years philosophers have been interested in the methodology of metaphysics. Most of these developments are related to formal work in logic or physics, often against the backdrop of the Carnap-Quine debate on ontology. Drawing on Quine’s later work, I argue that a psychological or cognitive perspective on metaphysical topics may be a valuable addition to contemporary metametaphysics. The method is illustrated by means of cognitive studies of the notions “identity,” “vagueness,” and “object” and is (...) compared to other extant metametaphysical positions. (shrink)

W. V. Quine assumed that in _Empiricism, Semantics, and Ontology Rudolf Carnap was attempting to dodge commitment to abstract entities--without either renouncing quantification over them or demonstrating their dispensability--by wielding the analytic/synthetic distinction against ontological issues. Quine's interpretation of Carnap's intent--and his criticism of it--is widely endorsed. But Carnap objected, I argue, not to abstract entities, but to his critics' suggestion that empiricism implies nominalism. Quine's and Carnap's views are therefore more akin than (...) Quine ever suspected. Unfortunately, Quine's misinterpretation of Carnap's position has led to a misunderstanding of the implications of Quine's own naturalistic turn for contemporary ontology.

The aim of the paper is to show that W. V. O. Quine's animadversions against modal logic did not get the same attention that is considered to be the case nowadays. The community of logicians focused solely on the technical aspects of C. I. Lewis’ systems and did not take Quine's arguments and remarks seriously—or at least seriously enough to respond. In order to assess Quine's place in the history, however, his relation to Carnap is considered (...) since their notorious break was about the status of extensionality and modal logic. Since much of the works about the history of analytic philosophy is centered on the relationship of Quine and Carnap, their break about modality deserves much more attention—it also sheds some light on why should anyone wonder about Quine's early arguments against modal logic. The paper ends with some further considerations regarding the early formation of modal logic and hitherto unconsidered problematic issues. (shrink)
