In this paper we discuss three examples of the appropriation of Kuhn’s ideas in philosophy of science. First we deal with classical logical empiricism. Perhaps somewhat surprisingly, the arch-logical empiricist Carnap considered Kuhn’s socio-historical account as a useful complementation, and not as a threat of the philosophy of science of logical empiricism. As a second example we consider the attempt of the so-called struc- turalist philosophy of science to provide a “rational reconstruction” of Kuhn’s approach. Finally, we will deal with (...) Friedman’s proposal to apply Kuhn’s ideas to the formulation of a modernized, historically enlightened Kantian approach that is based on the concept of a non-apodictic constitutive and historically moving a priori.

Predictivism asserts that novel confirmations carry special probative weight. Epistemic pluralism asserts that the judgments of agents (about, e.g., the probabilities of theories) carry epistemic import. In this paper, I propose a new theory of predictivism that is tailored to pluralistic evaluators of theories. I replace the orthodox notion of use-novelty with a notion of endorsement-novelty, and argue that the intuition that predictivism is true has two roots. I provide a detailed Bayesian rendering of this theory and argue that pluralistic (...) theory evaluation pervades scientific practice. I compare my account of predictivism with those of Maher and Worrall. Introduction Why construction is a red herring for pluralist evaluators The unvirtuous accommodator Virtuous endorsers and the two roots of predictivism The two roots in Bayesian terms: the priors and background beliefs of endorsers Who are the pluralist evaluators?

Idealist Heresies in Philosophy of Science: Cassirer, Carnap, and Kuhn. As common wisdom has it, philosophy of science in the analytic tradition and idealist philosophy are incompatible. Usually, not much effort is spent for explaining what is to be understood by idealism. Rather, it is taken for granted that idealism is an obsolete and unscientific philosophical account. In this paper it is argued that this thesis needs some qualification. Taking Carnap and Kuhn as paradigmatic examples of positivist and postpositivist philosophies (...) of science it is shown that these accounts share important features with Cassirer's idealist philosophy of science developed in the first half of this century. As it turns out, often Cassirer is more modern than those classical philosophers of (post)posivitist philosophy of science. For instance, Quine's criticism against Carnap's empiricist philosophy of science launched in Two Dogmas of Empiricism is anticipated by Cassirer for several decades. (shrink)

We compare Carnap's and Kuhn's views on science. Although there are important differences between them, the similarities are striking. The basis for the latter is a pragmatically oriented semantic conventionalist picture of science, which suggests that the view that post-positivist philosophy of science constitutes a radical revolution which has no interesting affinities with logical positivism must be seriously mistaken.

The Logical Reconstruction of the World (Aufbau) is oneof the major works of Rudolf Carnap in which he attempts to put an end to some of the traditional disputes in epistemology by using what he calls 'construction theory'. According to this theory, one or more constructional systems can be designed in which all the scientific and pre-scientific objects are logically made out of a limited number of basic elements. Carnap introduces some options for the basis of this system and chooses (...) the domain of the autopsychological, i.e., the domain of private elementary experiences, among them and tries to construct all the concepts out of them. This phenomenalistic reduction sometimes is seen as embracing a Cartesian dualism of mind and body or even a mentalistic monism. However, in this paper, I shall try to show that the traditional dualist-monist debates are among those disputes that the construction theory aims to get rid of. I will show that Carnap's position on the mind-body problem is really close to what Davidson later termed as 'Anomalous Monism' and that this is why Carnap fails to complete his logical construction at a crucial step. Whenever possible, logical constructions are to be substituted for inferred entities. (shrink)

This chapter examines the legacy of Kuhn’s Structure for normative philosophy of science. As an argument regarding the history of 20th century philosophy of science, I contend that the main legacy of Structure was destructive: Structure shifted philosophy of science away from addressing general normative philosophical issues (e.g., the demarcation problem, empirical testability) towards more deflationary and local approaches to normative issues. This is evident in the first generation of post-Structure philosophers of science in the 1980s and 1990s, who adopted (...) a pluralist approach to HPS. As a metaphilosophical argument regarding the methods adopted in HPS, I argue that there are a plurality of legitimate philosophical methodologies for inferring normative claims from historical cases. I frame this argument as a response to Pitt’s dilemma of case studies. I reject Pitt’s dilemma for its presupposition of an unrealistic and unfruitful standard (viz., epistemic certainty) for assessing HPS arguments and its analysis of philosophical methodology at the level of individual arguments. Pitt’s dilemma is most usefully understood as identifying potential points of criticism for HPS arguments. -/- The chapter begins with an examination of Kuhn’s normative philosophy of science in Structure and his position that historical cases provide evidence for philosophical claims. Kuhn’s philosophical methodology is insufficiently articulated, and his utilization of case studies is subject to objections (viz., interpretative bias, hasty generalization) implied by Pitt’s dilemma. I subsequently examine four post-Kuhnian methodological perspectives: (1) Ian Hacking’s particularism, (2) Helen Longino’s practice-based approach, (3) Michael Friedman’s neo-Kantianism, and (4) Hasok Chang’s complementary science. These views suggest alternative methodological strategies in HPS for addressing normative issues. I conclude by articulating some outstanding methodological challenges for the pluralist tradition of HPS—associated with the Stanford and Minnesota schools of philosophy of science—that emerged in the 1980s and remains influential.

Öz: Frege özel adların (ve diğer dilsel simgelerin) anlamları ve gönderimleri arasında ünlü ayrımını yaptığı “Anlam ve Gönderim Üzerine” (1948) adlı makalesinde, bu ayrımın önemi, gerekliliği ve sonuçları üzerine uzun değerlendirmeler yapar ancak özel adın anlamından tam olarak ne anlaşılması gerektiğinden yalnızca bir dipnotta kısaca söz eder. Örneğin “Aristoteles” özel adının anlamının Platon’un öğrencisi ve Büyük İskender’in öğretmeni ya da Stagira’da doğan Büyük İskender’in öğretmeni olarak alınabileceğini söyler. Burada dikkat çeken nokta örnekteki özel adın olası anlamları olarak gösterilen belirli betimlemelerin (...) de özel ad içeriyor olması. Anlamın Frege için bileşimsel olduğu, bir başka deyişle bir dilsel simgenin anlamının (varsa) parçalarının anlamlarınca belirlendiği düşünülürse, örnekteki belirli betimlemelerin anlamlarının saptanabilmesi için içerdikleri özel adların da anlamları saptanıp betimleme içinde geçtikleri yere konmalıdır. Bu işlem hiçbir özel ad kalmayana kadar sürdürülmelidir. Ancak biraz düşünülünce bir özel adın nesnesini tekil olarak betimleyecek ve içinde özel ad geçmeyecek bir betimleme bulmanın kolay olmadığı görülür. Örneğin yukarıdaki betimlemelerde geçen “Platon”, “Büyük İskender” ve “Stagira” gibi özel adların anlamları olabilecek ancak özel ad içermeyen betimlemeler bulmak pek kolay görünmüyor. Ortaya bir sonsuz gerileme sorunu çıkmış gibi duruyor. Frege’nin anlam-gönderim ayrımını için ciddi sonuçları olabilecek bu sorunu Frege çözebilir mi? Bu yazıda bu sorunun yanıtını arayacağım. Sorunu betimledikten sonra Frege’nin önündeki seçenekleri (örneğin bağlama duyarlı terimlerden (gösterme adılları veya belirteçler) yararlanma veya bağlamı sınırlama gibi) değerlendireceğim. -/- Abstract: In his “Sense and Reference” (1948), Frege makes his famous distinction between the sense and the reference of a proper name (and other signs) and discusses at length the significance, necessity and consequences of the distinction, but he explains how the sense of a proper name should be understood very briefly in a footnote. According to him, for example, the sense of the proper name “Aristotle” can be taken as the pupil of Plato and teacher of Alexander the Great or the teacher of Alexander the Great who was born in Stagira. What is interesting here is that the definite descriptions given as the possible senses of this proper name do themselves contain proper names too. Since the sense is something compositional for Frege, which means the sense of a linguistic sign is determined by its constituents (if there are any), in order to determine the sense of definite descriptions in question, we should first determine the senses of proper names they contain and substitute these senses with the proper names themselves. This process should continue until no proper name remains. However, it does not seem easy to find a definite description which describes the object of a proper name uniquely but contains no proper name itself. For instance, could we find appropriate senses that contain no proper name for “Plato”, “Alexander the Great” and “Stagira”? It does not seem likely. A problem of infinite regress appears to arise. Can Frege solve this problem, which poses a serious threat for his sensereference distinction? I will explore this problem in this paper. After explaining the problem, I will discuss the options (e.g. turning to indexicals or context restriction) Frege can take to deal with it. (shrink)

Huw Price has sketched a program for a globalized expressivism in support of which he has repeatedly invoked Rudolf Carnap. This paper argues that this is entirely appropriate, as Carnap had something quite similar in mind. However, it also argues that Price’s recent attempts to integrate Robert Brandom’s inferentialism to this program are less successful, and that a more empirically-oriented descriptive pragmatics along Carnapian lines would be a better fit with his original program than Brandom’s explicitly hermeneutical agenda.

In his late years, Thomas Kuhn became interested in the process of scientific specialization, which does not seem to possess the destructive element that is characteristic of scientific revolutions. It therefore makes sense to investigate whether and how Kuhn’s insights about specialization are consistent with, and actually fit, his model of scientific progress through revolutions. In this paper, I argue that the transition toward a new specialty corresponds to a revolutionary change for the group of scientists involved in such a (...) transition. I will clarify the role of the scientific community in revolutionary changes and characterize the incommensurability across specialties as possessing both semantic and methodological aspects. The discussion of the discovery of the structure of DNA will serve both as an illustration of my main argument and as reply to one criticism raised against Kuhn—namely, that his model cannot capture cases of revolutionary yet non-disruptive episodes of scientific progress. Revisiting Kuhn’s ideas on specialization will shed new light on some often overlooked features of scientific change. (shrink)

ABSTRACT This essay considers the relationship between history of science and philosophy of science from Thomas Kuhn to the present. This relationship, of course, has often been troubled, but there is now new hope for an ongoing productive interaction—due to an increasing awareness, among other things, of the mutual entanglement between the development of modern science and the development of modern philosophy on the part of both professional (historically minded) philosophers and professional historians of science. This idea is illustrated with (...) several examples, including the entanglement of Einstein's theory of relativity with logical empiricism and its precursors and the entanglement of the analytic tradition in philosophy first with mathematical logic and then (through mathematical logic) with the cognitive sciences. Against this background, finally, the essay considers the emergence of contemporary social and cultural history of science from the Kantian and neo‐Kantian philosophical traditions. (shrink)

My dissertation explores the ways in which Rudolf Carnap sought to make philosophy scientific by further developing recent interpretive efforts to explain Carnap’s mature philosophical work as a form of engineering. It does this by looking in detail at his philosophical practice in his most sustained mature project, his work on pure and applied inductive logic. I, first, specify the sort of engineering Carnap is engaged in as involving an engineering design problem and then draw out the complications of design (...) problems from current work in history of engineering and technology studies. I then model Carnap’s practice based on those lessons and uncover ways in which Carnap’s technical work in inductive logic takes some of these lessons on board. This shows ways in which Carnap’s philosophical project subtly changes right through his late work on induction, providing an important corrective to interpretations that ignore the work on inductive logic. Specifically, I show that paying attention to the historical details of Carnap’s attempt to apply his work in inductive logic to decision theory and theoretical statistics in the 1950s and 1960s helps us understand how Carnap develops and rearticulates the philosophical point of the practical/theoretical distinction in his late work, offering thus a new interpretation of Carnap’s technical work within the broader context of philosophy of science and analytical philosophy in general.

Recently, some philosophers of science (e.g., Gürol Irzik, Michael Friedman) have challenged the ‘received view’ on the relationship between Rudolf Carnap and Thomas Kuhn, suggesting that there is a close affinity (rather than opposition) between their philosophical views. In support of this argument, these authors cite Carnap and Kuhn’s similar views on incommensurability, theory-choice, and scientific revolutions. Against this revisionist view, I argue that the philosophical relationship between Carnap and Kuhn should be regarded as opposed rather than complementary. In particular, (...) I argue that a consideration of the fundamentally disparate nature of the broader philosophical projects of Carnap (logic of science) and Kuhn (providing a theory of scientific revolutions)renders the alleged similarities between their views superficial in comparison to their fundamental differences. In defense of the received view, I suggest that Carnap and Kuhn are model representatives of two contrasting styles of doing philosophy of science, viz., logical analysis and historical analysis respectively. This analysis clarifies the role played by Kuhn’s Structure of Scientific Revolutions in the demise of logical empiricism in the second half of the twentieth-century. (shrink)

Someone is “verballed” in the Anglo-Australian idiom if they have attributed to them statements they did not actually make and indeed have explicitly denied. We will examine the evidence that Kuhn and Feyerabend were verballed in this sense by their critics and that the role of the idea of incommensurability in their argumentation has been systematically misunderstood and -represented. In particular, we will see that neither Kuhn nor Feyerabend, despite what their critics often say about them, held that incommensurability of (...) theories implies the rational incomparability of theories. This is especially clear in the case of Feyerabend, whose argument is NOT that theories in a scientific tradition are on occasion incommensurable, but, rather, that, when the relations of theories in a tradition are represented in a particular way, they may on occasion be incommensurable according to that representation and hence incomparable if that representation is taken as providing the mechanisms of comparison. And the point of this claim is not to establish something about science, but, rather, to establish something about the representations of science which yield this result (i.e. that two theories might be incommensurable). Feyerabend in other words invokes incommensurability (according to the standards of a particular representation) as a reductio of that mode of representation. And this argument in fact depends precisely on the comparability of theories which are, according to the representation, incommensurable. Feyerabend’s argument is about the ways in which we should understand progress in science and he is concerned, in particular, to establish that a historically informed approach is superior to an approach which, if applicable, is applicable only to what he calls “abstract traditions”. Kuhn’s work, especially in the Postscript—1969, provides complementary materials, especially in relation to a collectivised and non-“algorithmic” account of theory choice across formally incommensurable paradigms.

The causal theory of reference is often taken to provide a solution to the problems, such as incomparability and referential discontinuity, that the meaning-change thesis raised. I show that Kuhn successfully questioned the causal theory and Putnam's idea that reference is determined via the sameness relation of essences that holds between a sample and other members of a kind in all possible worlds. Putnam's single ‘essential' properties may be necessary but not sufficient to determine membership in a kind category. Kuhn (...) argued that extension is fixed by similarity-dissimilarity relations that are liable to change in taxonomic reorganizations of science. *Received October 2009; revised January 2010. †To contact the author, please write to: Institute of Philosophy, University of Leiden, Martin de Vrieshof 4, 2300 RS Leiden, The Netherlands; e-mail: [email protected].

Thomas Kuhn’s relativistic position is usually expounded in terms of its subjectivist and irrationalist consequences and, accordingly, as a contribution to anti-scientificism. This paper explains his pluralism in semantics and ontology and shows in it a kind of relativism from which those consequences do not follow. It is also argued that, despite that, this version does not converge to empiricism or scientific realism.

It is generally thought that Carnap’s principle of tolerance cannot be integrated into a coherent overall conception of rationality. The doubts come from many sides, of which two are singled out. This paper argues that both are wrong, and that Carnapian rationality is a viable and perhaps quite interesting program for further development.

This is a two tiered investigation. On the one hand, the author presents a systematic account of the philosophy of Hilary Putnam. Being the first comprehensive account to be published in the German-speaking world, the author traces the development of Putnam's realism and philosophy of language and their connections from the early 1950's to 2000. Contrary to the popular view of the discontinuity of Putnam's philosophy, he demonstrates that Putnam maintains certain semantic, pragmatic and epistemological foundations for the rational confirmability, (...) fallibility and self-corrigibility of theoretical knowledge in the empirical sciences as a constant around which many other philosophical assumptions are allowed to vary under critical examination. The resulting view of Putnam's philosophical "position" is decidedly "anti-metaphysical" (contrary to the common association of his philosophy of language with e.g. Kripke's understanding of realism), but not fully "deflationary" (contrary to the reclamation of his criticism of realist metaphysics as Quinean or Rortyan skepticism). On the other hand, the author generalizes, in the second and third parts of the book, Putnam's now famous theory of meaning and reference to develop a framework for the pragmatics of semantic continuity and discontinuity, as well as conceptual change within general terms in empirical settings, like natural kind terms, theoretical terms in natural sciences and commonsense classifications. The third part presents, develops and defends the basic normative premisses as a pragmatic alternative to both, metaphysical (Kripke, Devitt) and sceptical approaches (Quine, Kuhn). The main result here is that many (if not all) preconditions for the semantic bahvior of 'rigid' general terms are not, as usually assumed, ontological in nature, but can be usefully framed as part of the pragmatics of general terms in epistemic practices counting with rational revisability.

The system of realist philosophy developed by John Anderson — situational realism — has recently been dismissed as ‘positivist’ by a prominent critical realist. The reason for this dismissal appears not to be the usual list of ideas deemed positivist, but the conviction that situational realism mistakenly defends a form of actualism, i.e. that to conceive of causal laws as constant conjunctions reduces the domain of the real to the domain of the actual. This is, in part, a misreading of (...) Anderson’s philosophy because, contrary to Hume’s constant conjunction account, Anderson viewed causation as pluralistic and non-linear. However, the critical realist charge does point to two important ontological differences between these realist philosophies — a levels-of-reality thesis and the notion of causal powers. Situational realism has always maintained that the arguments for both lead to difficulties that are logically insurmountable. Unfortunately, this is not addressed in the critical realists’ dismissal of Anderson’s philosophy. Regardless of who makes the charge of positivism, it frequently involves inattention to the real character of its target. (shrink)

This essay argues that post-analytic philosophy finds its origins not only in an invented tradition—that of ‘analytic philosophy’—but also in an invented dilemma: namely, the response to the allegedly overweening dominance of ‘positivism’ in American philosophy. I begin by surveying the problems with the folk wisdom about positivism and analytic philosophy. This pervasive narrative locates the emergence of post-analytic philosophy after a period of hegemony for logical positivism and cognate philosophical subfields. Taking seriously evidence indicating a distinct overlap in the (...) construction of the analytic and post-analytic traditions, I return to the founding moment of American analytic philosophy in the years immediately following World War II. What we see, I suggest, is not a reaction against a clearly defined and powerful logical positivist mainstream, but the careful, piecewise co-ordination of what would become characteristic ‘analytic’ modes of argument, problematics, and tool kits. Willard Van Orman Quine played a central role in this process, and for this reason I focus on the circumstances in which his field-defining 1951 article, ‘Two Dogmas of Empiricism’ was written and received. I conclude with the claim that both analytic and post-analytic philosophers relied on a peculiar image of the failure of logical positivism, and of the opportunities that failure presented. (shrink)

During the first two decades of the Cold War, a new kind of academic figure became prominent in American public life: the credentialed social scientist or expert in the sciences of administration who was also, to use the parlance of the time, a “man of affairs.” Some were academic high-fliers conscripted into government roles in which their intellectual and organizational talents could be exploited. McGeorge Bundy, Walt Rostow, and Robert McNamara are the archetypes of such persons. An overlapping group of (...) scholars became policymakers and political advisers on issues ranging from social welfare provision to nation-building in emerging postcolonial states. Many of these men—and almost without exception they were men—were also consummate operators within the patronage system that grew up around American universities after World War II. Postwar leaders of the social and administrative sciences such as Talcott Parsons and Herbert Simon were skilled scientific brokers of just this sort: good “committee men,” grant-getters, proponents of interdisciplinary inquiry, and institution-builders. This hard-nosed, suit-wearing, business-like persona was connected to new, technologically refined forms of social science. No longer sage-like social philosophers or hardscrabble, number-crunching empiricists, academic human scientists portrayed themselves as possessors of tools and programs designed for precision social engineering. Antediluvian “social science” was eschewed in favour of mathematical, behavioural, and systems-based approaches to “human relations” such as operations research, behavioral science, game theory, systems theory, and cognitive science.

Carnap wrote a continuation of his reply to Kaplan, which would, however, have made that reply, already by far the longest in the book, too long. So he set aside his projected notes for a continuation to serve as the basis for a separate paper, which he never got around to writing. It is transcribed here from his shorthand and translated into English, with some introductory notes to provide a little context.

W. V. Quine famously argues that though all knowledge is empirical, mathematics is entrenched relative to physics and the special sciences. Further, entrenchment accounts for the necessity of mathematics relative to these other disciplines. Michael Friedman challenges Quine’s view by appealing to historicism, the thesis that the nature of science is illuminated by taking into account its historical development. Friedman argues on historicist grounds that mathematical claims serve as principles constitutive of languages within which empirical claims in physics and the (...) special sciences can be formulated and tested, where these mathematical claims are themselves not empirical but conventional. For Friedman, their conventional, constitutive status accounts for the necessity of mathematics relative to these other disciplines. Here I evaluate Friedman’s challenge to Quine and Quine’s likely response. I then show that though we have reason to find Friedman’s challenge successful, his positive project requires further development before we can endorse it. (shrink)

In recent years, a revisionist process focused on logical positivism can be observed, particularly regarding Carnap’s work. In this paper, I argue against the interpretation that Kuhn’s The Structure of Scientific Revolutions having been published in the International Encyclopedia of Unified Science, co-edited by Carnap, is evidence of the revisionist idea that Carnap “would have found Structure philosophically congenial”. I claim that Kuhn’s book, from Carnap’s point of view, is not in philosophy of science but rather in history of science (...) (in the context of a sharp discovery–justification distinction). It could also explain the fact that, despite his sympathetic letters to Kuhn as editor, Carnap never refers to Kuhn’s book in his work in philosophy of science. (shrink)

Thomas S. Kuhn is famous both for his work on the Copernican Revolution and his ‘paradigm’ view of scientific revolutions. But Kuhn later abandoned the notion of paradigm in favour of a more ‘evolutionary’ view of the history of science. Kuhn’s position therefore moved closer to ‘continuity’ models of scientific progress, for instance ‘chain-of-reasoning’ models, originally championed by D. Shapere. The purpose of this paper is to contribute to the debate around Kuhn’s new ‘developmental’ view and to evaluate these competing (...) models with reference to some major innovations in the history of cosmology, from Copernicanism to modern cosmology. This evaluation is made possible through some unexpected overlap between Kuhn’s earlier discontinuity model and various versions of the later continuity models. It is the thesis of this paper that the ‘chain-of-reasoning’ model accounts better for the cosmological evidence than both Kuhn’s early paradigm model and his later developmental view of the history of science.
