Der vorliegende Band vereinigt die Akten des internationalen Schleiermacher-Kongresses 2021 und nimmt den Philosophen, Theologen, Pädagogen und Übersetzer Friedrich Schleiermacher (1768–1834) als Kommunikationstheoretiker in den Blick. Ob als Universitätslehrer, Kanzelredner, als politischer Reformer, Publizist, Salongänger oder Briefeschreiber – Schleiermacher war selbst ein begnadeter Kommunikator und im Begriff der Kommunikation bündeln sich wie in einem Brennglas viele zentrale Aspekte seines Denkens. Seine Philosophie, Theologie und philologische Praxis zeichnen sich durch ihre emphatische Prozesshaftigkeit jenseits starrer Systeme aus. Sich in Sprache manifestierendes Wissen, (...) moralisches Handeln, religiöses Erleben und der Entwurf gemeinschaftlicher Institutionen sind im beständigen Werden und nur im Austausch der miteinander streitenden, sich liebenden und hassenden, Ideen und Sinn entwerfenden und um Gemeinschaft und Individualität ringenden Menschen wirklich. Die Beiträge dieses Bandes gehen Schleiermachers Werk ebenso wie seiner gesellschaftlichen, kirchlichen und philologischen Praxis vor dem Hintergrund ihrer ideengeschichtlichen Verflechtung nach und aktualisieren sein Denken in Auseinandersetzung mit unterschiedlichen Positionen der Gegenwart.

In diesem Aufsatz, werde ich die Frage des Naturalismus in Plessners Philosophie des organischen Lebens und seiner amerikanischen Rezeption, in besonders die philosophischen-biologischen Schriften von Marjorie Grene, untersuchen. Die amerikanische Philosophin Grene war die Hauptvertreterin Plessners im Englischen Sprachraum in 20sten Jahrhundert, die Plessners anthropologischen Argumentation in ihren Schriften zur Philosophie der Biologie aufgenommen und verwendet hat. Grene kritisierte in ihren frühen Schriften Heidegger, Sartre, und die Existenzphilosophie, die das menschliche Dasein von der Natur radikal absondert und die negative Affekte (...) wie Angst hervorhebt, in Vergleich mit Plessners weiterem Blick der Leibhaften, Sinnlichen, Tierischen Entwicklung des menschlichen Lebens. Die menschliche Existenz kann nicht dualistisch, wo „keine Brücke über den Abgrund zwischen Mensch und Tier führt,“ sondern nur biologisch-lebensphilosophisch oder ökologisch verstanden werden. Plessner und Grene setzen sich mit dem Reduktionismus des modernen Naturalismus auseinander und zeigen, wie das Natürliche weiter und ergänzt gedacht werden muss, weil der Naturalismus keine ausreichenden Begriffe für die Auslegung der Erscheinungen und Ausdrucksformen des organischen Lebens besitzt. Die Unterscheidung zwischen der "zentrischen Positionalität" des Tiers und der "exzentrischen Positionalität" des menschlichen Tiers ermöglicht eine holistisch aber differenzierte Beschreibung der Natur und Kultur, insbesondere die natürlichen Künstlichkeit, die der Kultur und das des gesellschaftlichen Lebens. Diese sind Grundlage für die geschichtliche und soziale Bildung, Aufbau, und Strukturierung der natürlichen Spontaneität, Produktivität, und Expressivität des Lebens und ermöglichen die dezentrierte, utopische, und persönliche Individuation der einzelnen Menschen im Lebenszusammenhang, was wichtige soziologische und auch ethische und politische Konsequenzen für Plessner und Grene hat: Der Mensch ist ein natürliches biologisches Individuum, das durchaus fähig ist, eine verantwortliche Person zu werden , und zwar durch die umfassende Beteiligung an (oder als ein einzigartiger Ausdruck) einer Kultur.

Alex Orenstein: “Inscrutability Scrutinized”: This is a reply to Quine's comments on an earlier paper. In his comments on that earlier paper Quine acknowledged that distinguishing the inscrutability of reference from the indeterminacy of meaning might be preferable to other of his ways of referring to this distinction. He also agreed that inscrutability of reference is a strong claim, a “thesis”, proven as per model theory. His examples of inscrutability are examined and supplemented with other examples. By contrast, indeterminacy of (...) meaning is merely a “conjecture,” a product of Quine's distinctive behaviorist approach. It is made clear that Quine's distinctive ‘stimulus meaning’ is a non‐decomposable idiom. Stimulus meaning is no more a species of meaning than toy horse is a species of horse. I exploit a view he introduced elsewhere when discussing choosing between intuitionist and classical logic. Quine's ersatz conception of meaning and its byproducts should be regarded along similar lines as the intuitionism versus classical logic debate: not as “denying a doctrine but as changing the subject.”.

This article critically assesses the empirical research that leads Quine, in his posthumously published work, to abandon his empiricist principle that humans do not have any innate concepts, or knowledge. It is the same empirical research that Penelope Maddy capitalizes on to develop her own contributions to naturalized epistemology, and it has been pioneered by developmental psychologist Elisabeth Spelke. Spelke employs the method of habituation and preferential looking to argue that human infants have innate concepts, and that they have some (...) knowledge about what can and cannot happen to physical objects. Taking into account empirical studies as well as methodological considerations, this article examines whether this research can support these strong philosophical conclusions drawn from it, finding that it likely cannot provide such support.

As analytic philosophy is becoming increasingly aware of and interested in its own history, the study of that field is broadening to include, not just its earliest beginnings, but also the mid-twentieth century. One of the towering figures of this epoch is W.V. Quine (1908-2000), champion of naturalism in philosophy of science, pioneer of mathematical logic, trying to unite an austerely physicalist theory of the world with the truths of mathematics, psychology, and linguistics. Quine's posthumous papers, notes, and drafts revealing (...) the development of his views in the forties have recently begun to be published, as well as careful philosophical studies of, for instance, the evolution of his key doctrine that mathematical and logical truth are continuous with, not divorced from, the truths of natural science. But one central text has remained unexplored: Quine's Portuguese-language book on logic, his 'farewell for now' to the discipline as he embarked on an assignment in the Navy in WWII. Anglophone philosophers have neglected this book because they could not read it. Jointly with colleagues, I have completed the first full English translation of this book. In this accompanying paper I draw out the main philosophical contributions Quine made in the book, placing them in their historical context and relating them to Quine's overall philosophical development during the period. Besides significant developments in the evolution of Quine's views on meaning and analyticity, I argue, this book is also driven by Quine's indebtedness to Russell and Whitehead, Tarski, and Frege, and contains crucial developments in his thinking on philosophy of logic and ontology. This includes early versions of some arguments from 'On What There Is', four-dimensionalism, and virtual set theory. (shrink)

While Quine’s linguistic behaviorism is well-known, his Kant Lectures contain one of his most detailed discussions of behaviorism in psychology and the philosophy of mind. Quine clarifies the nature of his psychological commitments by arguing for a modest view that is against ‘excessively restrictive’ variants of behaviorism while maintaining ‘a good measure of behaviorist discipline…to keep [our mental] terms under control’. In this paper, I use Quine’s Kant Lectures to reconstruct his position. I distinguish three types of behaviorism in psychology (...) and the philosophy of mind: ontological behaviorism, logical behaviorism, and epistemological behaviorism. I then consider Quine’s perspective on each of these views and argue that he does not fully accept any of them. By combining these perspectives we arrive at Quine’s surprisingly subtle view about behaviorism in psychology. (shrink)

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.

In 1902 there arrived in Jena a letter from Russell laying out a proof that shattered Frege’s confidence in logicism, which is widely taken to be the doctrine according to which every truth of arithmetic is re-expressible without relevant loss as a provable truth about a purely logical object. Frege was persuaded that Russell had exposed a pathology in logicism, which faced him with the task of examining its symptoms, diagnosing its cause, assessing its seriousness, arriving at a treatment option, (...) and making an estimate of future prospects. The symptom was the contradiction that had crept into naïve set theory in the form of the set that provably is and is not its own member. The diagnosis was that it is caused by Basic Law V of the Grundgesetze (Frege, In: Grundgesetze der Arithmetik: Begrifsschriftlich abgeleitet, Jena: Herman Pohle, 1893/1903. Translated into English as Basic Laws of Arithmetic, also edited by Philip A. Ebert and Marcus Rossberg, with Crispin Wright, Oxford: Oxford University Press, 2013). Triage answers the question, “How bad is it?” The answer was that the contradiction irreparably destroys the logicist project. The treatment option was nil. The disease was untreatable. In due course, the prognosis turned out to be that a scaled-down Fregean logic could have an honourable life as a theory inference for various domains of mathematical discourse, but not for domains containing the logical objects required for logicism. Since there aren’t such objects, there aren’t such domains. On the face of it, Frege’s logicist collapse is astonishing. Why wouldn’t he have repaired the fault in Law V and gone back to the business of bringing logicism to an assured realization? In the course of our reflections, we will have nice occasion to consider the good it might have done Frege to have booked some time with Aristotle had he been able to. By the time we’re finished, we’ll have cause to think that in the end the Russell might well have begged the question against Frege. (shrink)

Hume seems to have discarded with final causes and teleology. However, his invocation of a pre-established harmony between the course of nature and the succession of our ideas suggests otherwise. This paper takes Hume’s general strategy of shifting to the external perspective into account, and argues that the seemingly internal property of force and vivacity are, in fact, functional-teleological properties. Force and vivacity bears many explanatory burdens: It explains the difference between imagination and memory, between conception and belief, and it (...) establishes causal necessity. What kind of property is this supposed to be? We can answer this question by taking into account Hume’s explanation of the way in which this very property is communicated in the cases of ideas of memory and belief, and of the function it performs in these cases. It will be argued that force and vivacity is not an intrinsic, phenomenal property of ideas. It is a relational and historical property. A major objective of the paper is the application of this interpretation from the case of ideas to the case of impression. What kind of history could transfer force and vivacity to impressions? Answer: natural history. By a careful examination of passages concerning innate capacities, passions, and animal instincts, we can make sense of the tenet that impressions have force and vivacity because of our natural history. It will be suggested that Hume’s philosophy of mind is fit to integrate Darwinian Design as an explanatory corner-stone. Hume, so scheint, ist ein scharfer Kritiker von Finalursachen und Teleologie. Seine häufig als ironisch missverstandene Berufung auf eine Art „prästabilierter Harmonie“ zwischen Naturverläufen und Ideenabfolgen verweist jedoch auf eine andere Lesart. Der folgende Essay behauptet, indem er Humes explanatorische Strategie betont, etwa im Falle seiner berühmten Lösung der skeptischen Zweifele zur Kausalität zu einer externen Perspektive zu wechseln, dass es sich bei der scheinbar geistinternen Eigenschaft „Kraft und Lebendigkeit“ tatsächlich um eine teleologisch- historische Eigenschaft handelt. Kraft und Lebendigkeit leisten in Humes Philosophie des Geistes eine große Erklärungsarbeit: Sie erklären den Unterscheid zwischen Vorstellung und Erinnerung, zwischen Vorstellung und Überzeugung, und sie stellen die wesentliche Zutat der kausalen Notwendigkeit dar. Doch um welche Art Eigenschaft handelt es sich? Diese Frage kannmit Blick auf Humes Ausführung darüber beantwortet werden, wie diese Eigenschaft auf Ideen der Erinnerung und auf Überzeugungsideen übertragen wird, und v.a. mit Blick auf die Funktion, die diese Eigenschaft übernimmt. Es soll gezeigt werden, dass es sich bei Kraft und Lebendigkeit um keine intrinsische, phänomenale Eigenschaft von Ideen handelt, sondern um eine relationale, historische Eigenschaft. Ein wichtiges Ziel des Essays besteht darin, diese Deutung von Ideen auf Eindrücke zu übertragen. Inwiefern kann es sich bei der Kraft und Lebendigkeit von Eindrücken umeine relationale und historische Eigenschaft handeln? Die Antwort findet sich in der Naturgeschichte, wie mit Verweis auf Humes Ausführungen zu angeborenen Fähigkeiten, Leidenschaften und tierlichen Instinkten gezeigt werden kann. Die Stoßrichtung des Essays besagt, dass Humes Philosophie des Geistes durchaus mit einer Darwinschen Auffassung des Geistes zusammengeführt werden kann. (shrink)

in april 1933, two bright young Ph.D.s were elected to the Harvard Society of Fellows: the psychologist B. F. Skinner and the philosopher/logician W. V. Quine. Both men would become among the most influential scholars of their time; Skinner leads the "Top 100 Most Eminent Psychologists of the 20th Century," whereas philosophers have selected Quine as the most important Anglophone philosopher after the Second World War.1 At the height of their fame, Skinner and Quine became "Edgar Pierce twins"; the latter (...) obtaining the endowed chair at Harvard's department of philosophy, the former taking up the position at Harvard's psychology department.2Besides these biographical parallels, there also...

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.

Quine's argument for a naturalized epistemology is routinely perceived as an argument from despair: traditional epistemology must be abandoned because all attempts to deduce our scientific theories from sense experience have failed. In this paper, I will show that this picture is historically inaccurate and that Quine's argument against first philosophy is considerably stronger and subtler than the standard conception suggests. For Quine, the first philosopher's quest for foundations is inherently incoherent; the very idea of a self-sufficient sense datum language (...) is a mistake, there is no science-independent perspective from which to validate science. I will argue that a great deal of the confusion surrounding Quine's argument is prompted by certain phrases in his seminal ‘Epistemology Naturalized’. Scrutinizing Quine's work both before and after the latter paper provides a better key to understanding his remarkable views about the epistemological relation between theory and evidence. (shrink)

Quine is routinely perceived as saving metaphysics from Carnapian positivism. Where Carnap rejects metaphysical existence claims as meaningless, Quine is taken to restore their intelligibility by dismantling the former’s internal–external distinction. The problem with this picture, however, is that it does not sit well with the fact that Quine, on many occasions, has argued that metaphysical existence claims ought to be dismissed. Setting aside the hypothesis that Quine’s metaphysical position is incoherent, one has to conclude that his views on metaphysics (...) are subtler than is often presupposed; both the received view that Quine saved metaphysics and the opposite view that Carnap and Quine are on the same anti-metaphysical team seem too one-sided if we take seriously Quine’s own pronouncements on the issue. In this paper, I offer a detailed reconstruction of Quine’s perspective on metaphysical existence claims. Scrutinizing his published work as well as unpublished papers, letters, and notebooks, I show how Quine is able to both blur the boundary between scientific sense and metaphysical nonsense and to argue that we cannot ask what reality is really like in a distinctively philosophical way. I argue that although Quine’s position is much closer to Carnap’s than the received view suggests, it still differs in two crucial respects. (shrink)

Quine's holistic empiricist account of scientific inquiry can be characterized by three constitutive principles: *noncontradiction*, *universal revisability* and *pragmatic ordering*. We show that these constitutive principles cannot be regarded as statements within a holistic empiricist's scientific theory of the world. This claim is a corollary of our refutation of Katz's [1998, 2002] argument that holistic empiricism suffers from what he calls the Revisability Paradox. According to Katz, Quine's empiricism is incoherent because its constitutive principles cannot themselves be rationally revised. Using (...) Gärdenfors and Makinson's logic of belief revision based on epistemic entrenchment, we argue that Katz wrongly assumes that the constitutive principles are *statements* within a holistic empiricist's theory of the world. Instead, we show that constitutive principles are best seen as *properties* of a holistic empiricist's theory of scientific inquiry and we submit that, without Katz's mistaken assumption, the paradox cannot be formulated. We argue that our perspective on the status of constitutive principles is perfectly in line with Quinean orthodoxy. In conclusion, we compare our findings with van Fraassen's [2002] argument that we should think of empiricism as a stance, rather than as a doctrine. (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..

Given W.V. Quine’s and Donald Davidson’s extensive agreement about much of the philosophy of language and mind, and the obvious methodological parallels between Quine’s radical translation and Davidson’s radical interpretation, many—including Quine and Davidson—are puzzled by their occasional disagreements. I argue for the importance of attending to these disagreements, not just because doing so deepens our understanding of these influential thinkers, but because they are in fact the shadows thrown from two distinct conceptions of philosophical inquiry: Quine’s “naturalism” and what (...) I call Davidson’s “humanism.” The clash between Quine and Davidson thus provides valuable insight into the history of analytic naturalism and its malcontents. (shrink)

A. W. Carus champions Rudolf Carnap’s ideal of explication as a model for liberal political deliberation. Constructing a linguistic framework for discussing social problems, he argues, promotes the resolution of our disputes. To flesh out and assess this proposal, I examine debate about the social institutions of marriage and adoption. Against Carus, I argue that not all citizens would accept the pragmatic principles underlying Carnap’s ideal. Nevertheless, explication may facilitate inquiry in the social sciences and be used to create models (...) that help us to understand past disputes. This latter application reveals explication’s potential for refining the social histories that inform contemporary political discourse. (shrink)

In his “Wissenschaftslogik: The Role of Logic in the Philosophy of Science,” Michael Friedman argues that Carnap’s philosophy of science “is fundamentally anti-metaphysical—he aims to use the tools of mathematical logic to dissolve rather [than] solve traditional philosophical problems—and it is precisely this point that is missed by his logically-minded contemporaries such as Hempel and Quine”. In this paper, I take issue with this claim, arguing that Quine, too, is a part of this anti-metaphysical tradition. I begin in section I (...) with Russell’s account of scientific philosophy, focusing on its critique of metaphysics and its reliance on logical constructions. I then argue that each of Carnap and Quine take up this call to scientific philosophizing but that they both find Russell’s account of logic wanting. In section II, I first provide an account of Carnap’s critique of metaphysics and its reliance on developments in logic. This is followed by a discussion of his appeal to the analytic/synthetic distinction so as to improve upon Russell’s account of logic. Section III follows this same structure but focuses on Quine. In the end, though, Quine turns not to the analytic/synthetic distinction but to holism to provide an account of logic suitable to scientific philosophy. Carnap had claimed to be “more Russellian than Russell,” and in this final move by Quine I argue that he is “being more Carnapian than Carnap.” I conclude by showing how, contrary to Friedman’s view, Quine’s rejection of the analytic/synthetic distinction does not yield a return to the kind metaphysics that he, Carnap, and Russell all objected to. (shrink)

W. V. O. Quine’s assault on the analytic/synthetic distinction is one of the most celebrated events in the history of twentieth century philosophy. This paper shines a light on Quine’s own understanding of the history of this distinction. More specifically, this paper argues, contrary to what seems to be the received view, that Quine explicitly recognized a kindred subversive spirit in David Hume.

This paper investigates the relation between Carnap and Quine’s views on analyticity on the one hand, and their views on philosophical analysis or explication on the other. I argue that the stance each takes on what constitutes a successful explication largely dictates the view they take on analyticity. I show that although acknowledged by neither party (in fact Quine frequently expressed his agreement with Carnap on this subject) their views on explication are substantially different. I argue that this difference not (...) only explains their differences on the question of analyticity, but points to a Quinean way to answer a challenge that Quine posed to Carnap. The answer to this challenge leads to a Quinean view of analyticity such that arithmetical truths are analytic, according to Quine’s own remarks, and set theory is at least defensibly analytic. (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. (shrink)

As against the view represented here by Peter Hacker and John Canfield, I urge that the philosophies of Quine and Wittgenstein can be reconciled. Both replace the orthodox view of language as resting on reference: Quine with the notion of linguistic disposition, Wittgenstein with the notions of grammar and forms of life. I argue that Wittgenstein's insistence, in the rule-following discussion, that at bottom these are matters of practice, of ‘what we do’, is not only compatible in a rough sort (...) of way with Quine's outlook, but is very close to Quine's naturalistic view of language. And I argue that the likely objections to this can on the one hand be explained away as Quine's having been interested in a very narrow slice of language in comparison with Wittgenstein, and on the other by a failure to take into account later developments in Quine’s views. (shrink)

Quine’s naturalism has no room for a point of view outside science from which one might criticize science, or a transcendental point of view from which one could ask questions about the adequacy of science with respect to reality (‘as it is in itself ’). Adrian Moore sniffs out some genuine tensions in this, arguing in effect that Quine is forced by his own views to admit those sorts of questions as legitimate. I venture that Quine, even if he would (...) grant that the posing of such questions is an inevitable feature of reason in some sense, would take such curiosity to be strictly speaking a mistake, something like that of thinking there must be a single truth-predicate for all levels of Tarski’s hierarchy. (shrink)

Central elements of W. V. Quine’s epistemology are widely and deeply misunderstood, including the following. He held from first to last that our evidence consists of the stimulations of our sense organs, and of our observations, and of our sensory experiences; meeting the interpretive challenge this poses is a sine qua non of understanding his epistemology. He counted both “This is blue” and “This looks blue” as observation sentences. He took introspective reports to have a high degree of certainty. He (...) endorsed outright Hume’s “skeptical” argument concerning induction. His naturalized epistemology is simply naturalistic, or scientific, epistemology stripped of the project of rational reconstruction, and is thoroughly normative. Quine was unconditionally a scientific philosopher who took our theories to be answerable ultimately to our perceptual experiences (sensations)—and conditionally an empiricist, empiricism being a scientific theory that has no competitors worthy of the name. I attempt to make all of this clear, and conclude by offering a concise formulation of his epistemology. (shrink)

Recent scholarship indicates that Quine’s “Truth by Convention” does not present the radical critiques of analytic truth found fifteen years later in “Two Dogmas of Empiricism.” This prompts a historical question: what caused Quine’s radicalization? I argue that two crucial components of Quine’s development can be traced to the academic year 1940–1941, when he, Russell, Carnap, Tarski, Hempel, and Goodman were all at Harvard together. First, during those meetings, Quine recognizes that Carnap has abandoned the extensional, syntactic approach to philosophical (...) analysis, an approach espoused in Carnap’s 1934 Logical Syntax of Language, and which Quine endorsed his entire career. Second, Tarski presents Quine with a philosophically well-motivated reason to think that an apparently analytic discipline, arithmetic, could be synthetic; this reflects one of the central assertions found in “Two Dogmas” but not in “Truth by Convention.” I use this account of Quine’s development to resolve a dispute between Creath and Mancosu concerning the timeline for Quine’s evolving critiques of analyticity. (shrink)

The pluralist sheds the more traditional ideas of truth and ontology. This is dangerous, because it threatens instability of the theory. To lend stability to his philosophy, the pluralist trades truth and ontology for rigour and other ‘fixtures’. Fixtures are the steady goal posts. They are the parts of a theory that stay fixed across a pair of theories, and allow us to make translations and comparisons. They can ultimately be moved, but we tend to keep them fixed temporarily. Apart (...) from considering rigour of proof as a fixture, I discuss fixed models, invariant notions and fixed information about objects across theories. There are other fixtures, but it is enough to start with these. (shrink)

W. V. Quine thinks logical truth can be defined in purely extensional terms, as follows: a logical truth is a true sentence that exemplifies a logical form all of whose instances are true. P. F. Strawson objects that one cannot say what it is for a particular use of a sentence to exemplify a logical form without appealing to intensional notions, and hence that Quine's efforts to define logical truth in purely extensional terms cannot succeed. Quine's reply to this criticism (...) is confused in ways that have not yet been noticed in the literature. This may seem to favour Strawson's side of the debate. In fact, however, a proper analysis of the difficulties that Quine's reply faces suggests a new way to clarify and defend the view that logical truth can be defined in purely extensional terms. (shrink)

In this article, I analyze Quine’s conception of science, which is a radical defence of extensionalism on the grounds that first‐order logic is the most adequate logic for science. I examine some criticisms addressed to it, which show the role of modalities and probabilities in science and argue that Quine’s treatment of probability minimizes the intensional character of scientific language and methods by considering that probability is extensionalizable. But this extensionalizing leads to untenable results in some cases and is not (...) consistent with the fact that Quine himself admits confirmation which includes probability. Quine’s extensionalism does not account for this fact and then seems unrealistic, even if science ought to be extensional in so far as it is descriptive and mathematically expressible. (shrink)

In this thesis, I elaborate and defend Donald Davidson's account of knowing one's own mental states that exhibit first-person authority. To that end, I place Davidson's account among others in the philosophical landscape concerning self-knowledge. Next, I examine his response to philosophical challenges that arise from mental content externalism and self-deception. Finally, I draw some insights froms Davidson's account to the broader aims of epsitemology.

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.

Disagreement over what exists is so fundamental that it tends to hinder or even to block dialogue among disputants. The various controversies between believers and atheists, or realists and nominalists, are only two kinds of examples. Interested in contributing to the intelligibility of the debate on ontology, in 1939 Willard van Orman Quine began a series of works which introduces the notion of ontological commitment and proposes an allegedly objective criterion to identify the exact conditions under which a theoretical discourse (...) signals an assumption of existence. I intend to present the concept of ontological commitment and the Quinean criterion, to expose and evaluate some of the many criticisms to which the criterion has subject and to situate it in the context of Quine’s philosophy. As a product of such analyses, I hope to contribute to the discussion on the application and relevance of the notion of ontological commitment. (shrink)

This paper (in Finnish) concerns the ontological status of categories of entities. I argue that categories are not be considered as further entities. Rather, it is suffcient for entities belonging to the same category that they are in exactly the same formal ontological relations and have the same general category features.

The textbook-like history of analytic philosophy is a history of myths, re-ceived views and dogmas. Though mainly the last few years have witnessed a huge amount of historical work that aimed to reconsider our narratives of the history of ana-lytic philosophy there is still a lot to do. The present study is meant to present such a micro story which is still quite untouched by historians. According to the received view Kripke has defeated all the arguments of Quine against quantified (...) modal logic and thus it became a respectful tool for philosophers. If we accept the historical interpreta-tion of the network between Quine, Kripke and modal logic, which is to be presented here, we have to conclude that Quine’s real philosophical animadversions against the modalities are still on the table: though Kripke has provided some important (formal-logical) answers, Quine’s animadversions are still viable and worthy of further consideration.
