Thomas Kuhn

According to falsificationism, a theory is scientific if it can be incompatible with some empirically testable statements. This epistemological approach has been criticized because, in practice, it is impossible to decide when a particular fact should be considered incompatible with a theory. These criticisms, however, neglect the fact that the Popperian sense of falsification is a “logical sense.” Thus, the Popperian criterion of falsifiability only requires that, assuming certain auxiliary hypotheses, the theory in question be logically incompatible with some empirically (...) testable statements. This paper presents a reassessment of these criticisms, justifying that the criterion of falsifiability is unrenounceable insofar as our best theories should aspire to satisfy it. (shrink)

Pendant un demi-siècle, la méthode appropriée en philosophie des sciences dans la tradition continentale était l'étude historique ; dans la tradition anglosaxonne, l'analyse logique. Ce clivage au sein du discours philosophique s'est grandement estompé de nos jours. D'une part, Kuhn a défendu la pertinence philosophique de l'histoire des sciences. D'autre part, Vuillemin et Gilles-Gaston Granger ont promu l'étude de la philosophie analytique et l'emploi de ses techniques logiques. Le rapprochement des deux traditions a pris encore une nouvelle tournure dans les (...) derniers textes de Feyerabend et dans les travaux de Ian Hacking. Celui-ci associe délibérément les instruments historiques de l'école française avec les procédés logiques de l'école nordaméricaine. Quelle est la signification de ce rapprochement ? Quels problèmes fait-il surgir ? Quelles directions de recherche ouvre-t-il ? Telles sont les questions que nous aborderons par le biais d'une étude comparée de certains développements récents de la philosophie des sciences en France et en Amérique du Nord. For over half a century the continental tradition favored a historical method in philosophy of science, while the Anglo-American tradition promoted a logical method. In recent years this contrast has tended to lessen. On the one hand, there has been a growing interest since the 1970s in France for the analytic tradition, due to the pioneering studies of Vuillemin and Gilles-Gaston Granger. On the other hand, Kuhn has brought out the philosophical relevance of history of science. This tendency takes a new turn in Feyerabend's final texts as well as in the works of Ian Hacking. The latter deliberately combines the historical instruments of the French school with the logical techniques of the North-American school. How to understand this evolution ? What directions of research does it open up ? I address these questions by way of a comparative study of some recent developments in philosophy of science both in France and North America. (shrink)

Philosophers have long tried to understand scientific change in terms of a dynamics of revision within ‘theoretical frameworks,’ ‘disciplinary matrices,’ ‘scientific paradigms’ or ‘conceptual schemes.’ No-one, however, has made clear precisely how one might model such a conceptual scheme, nor what form change dynamics within such a structure could be expected to take. In this paper we take some first steps in applying network theory to the issue, modeling conceptual schemes as simple networks and the dynamics of change as cascades (...) on those networks. The results allow a new understanding of two traditional approaches—Popper and Kuhn—as well as introducing the intriguing prospect of viewing scientific change using the metaphor of selforganizing criticality.

I will present a comparative analysis between Thomas Kuhn's The Copernican Revolution published in 1957 and The Structure of Scientific Revolutions published in 1962, ir order to identify divergences in the views contained in each work. I shall set forth a comparative analysis of the historiographical assumptions employed by Kuhn in each of his books. I will explore some proposals which have pointed out several discontinuities between both books, as I introduce some tools to widen this interpretative trend. I will (...) argue that although Kuhn’s work in 1957 contains some concerns and problems which anticipate his later stances, these anticipations coexist with historiographical formulations and premises which are incompatible with the core of SSR. Therefore, I will assert that Kuhn adopts different historiographical frameworks in CR and in SSR. Finally, I will conclude that these differences are expressions of Kuhn's adoption of a more externalist view in the former, and a more internalist frame in the latter. (shrink)

Changes of theories are major events in science. Two main types of questions may be asked about them: i) how do scientists choose new theories?, and ii) how is consensus formed? Generally, philosophers do not distinguish these two questions. Kuhn, on the contrary, offers very different answers to each of these questions. Theory-choice, on the one hand, is explained through the application of epistemic criteria, such as accuracy and consistency; nonetheless, because these values do not prescribe a single choice, consensus (...) formation, on the other hand, is explained through a series of socio-epistemic mechanisms, namely: scientific pedagogy, diffusion and production of knowledge within the community, and restructuring of the scientific field. These mechanisms are the basis of Kuhn’s social epistemology, in that they are not restricted to sociology nor epistemology, encompassing both social interactions and epistemic evaluations of theories. Keywords: Thomas Kuhn, consensus formation, social epistemology. (shrink)

The paper takes off from the suggestion of Jouni-Matti Kuukkanen that Kuhn’s account of science may be understood in coherentist terms. There are coherentist themes in Kuhn’s philosophy of science. But one crucial element is lacking. Kuhn does not deny the existence of basic beliefs which have a non-doxastic source of justification. Nor does he assert that epistemic justification only derives from inferential relationships between non-basic beliefs. Despite this, the coherentist interpretation is promising and I develop it further in this (...) paper. I raise the question of whether Kuhn’s account of science can deal with the input objection to coherentism. I argue that the role played by problems in Kuhn’s theory of science ensures that there is input from the external world into scientists’ belief-systems. I follow Hoyningen-Huene in pointing to the causal role played by the external world in determining perceptual states. I next turn to the question of whether Kuhn’s rejection of foundationalism implies coherentism. I argue that Kuhn’s rejection of the one-to-one relation between object and experience is compatible with a foundationalist account of justification. Nor does Kuhn’s rejection of the given entail the same coherentist implications as Sellars’ critique of the myth of the given. (shrink)

This is a book review of Brad Wray (ed.) Interpreting Kuhn: Critical Essays.

This paper is about the remarkable explosion in the literature on thought experiments since the 1980s. It enters uncharted territory. The year 1986 is of particular interest: James R. Brown presents his Platonism about thought experiments for the first time in Dubrovnik, and in Pittsburgh John D. Norton shares his empiricist approach with participants in what was probably the 20th century’s very first major conference on thought experiments. It was the time when philosophy of science had taken a pluralistic turn, (...) and the paper develops the notion that this is a key factor in the outburst of discussions about thought experiments in the 1980s.

Taking a cue from remarks Thomas Kuhn makes in 1990 about the historical turn in philosophy of science, I examine the history of history and philosophy of science within parts of the British philosophical context in the 1950s and early 1960s. During this time, ordinary language philosophy's influence was at its peak. I argue that the ordinary language philosophers' methodological recommendation to analyze actual linguistic practice influences several prominent criticisms of the deductive-nomological model of scientific explanation and that these criticisms (...) relate to the historical turn in philosophy of science. To show these connections, I primarily examine the work of Stephen Toulmin, who taught at Oxford from 1949 to 1954, and Michael Scriven, who completed a dissertation on explanation under Gilbert Ryle and R.B. Braithwaite in 1956. I also consider Mary Hesse's appeal to an ordinary language-influenced account of meaning in her account of the role of models and analogies in scientific reasoning, and W.H. Watson's Wittgensteinian philosophy of science, an early influence on Toulmin. I think there are two upshots to my historical sketch. First, it fills out details of the move away from logical positivism to more historical- and practice-focused philosophies of science. Second, questions about linguistic meaning and the proper targets and aims of philosophical analysis are part and parcel of the historical turn, as well as its reception. Looking at the philosophical background during which so-called linguistic philosophers also had a hand in bringing these questions to prominence helps us understand why. (shrink)

This book addresses how our revisionary practices account for relations between texts and how they are read. It offers an overarching philosophy of revision concerning works of fiction, fact, and faith, revealing unexpected insights about the philosophy of language, the metaphysics of fact and fiction, and the history and philosophy of science and religion. It will be of interest to a wide range of scholars and advanced students working in philosophy of language, metaphysics, philosophy of literature, literary theory and criticism, (...) and history and philosophy of science and religion.

The Quest for Physical Theory (QPT) comprises the eight Lowell lectures that Kuhn gave on Tuesdays and Fridays in March 1951 in the Lecture Hall of the Boston Library. He was 28 years old at the time, a member of the Harvard Society of Fellows, a recent Harvard PhD in Physics (1949), and an instructor in the general-education course on science set up by James Conant, Harvard’s President. Kuhn seized the opportunity of the Lowell Lectures to present his new, and (...) ground-breaking at the time, take on science which was shaped by Kuhn’s forays in psychology, philosophy, history, and logic. It is obvious from reading the lectures that Kuhn was very confident of his views and was aiming to jolt the public with his revisionary account. To a complacent audience, accustomed to the standard, textbook picture of science, he hurled the provocative claims that there are no pure facts, that prejudice plays a decisive role in scientific practice, that the then-current history of science fabricated mythologies about past science, that perception is not passive, and that the overthrow of a theory does not add to previous knowledge. All these claims more than foreshadow the basic elements of Kuhn’s model in The Structure of Scientific Revolutions (SSR). It is not just that the lectures speak to the emergence of Kuhn’s ideas that were later refined, as George Reisch, the editor of QPT, says in his introductory essay. The lectures show that Kuhn had conceived his model, almost in its entirety, very early on, which means that the much-debated influence exercised on him by later works, such as Toulmin’s, Hanson’s, or Polanyi’s in the 1950s, was secondary to the exploratory readings of his youth. These later influences must have solidified his early conception. (shrink)

Scientists often diverge widely when choosing between research programs. This can seem to be rooted in disagreements about which of several theories, competing to address shared questions or phenomena, is currently the most epistemically or explanatorily valuable—i.e. most successful. But many such cases are actually more directly rooted in differing judgments of pursuit-worthiness, concerning which theory will be best down the line, or which addresses the most significant data or questions. Using case studies from 16th-century astronomy and 20th-century geology and (...) biology, I argue that divergent theory choice is thus often driven by considerations of scientific process, even where direct epistemic or explanatory evaluation of its final products appears more relevant. Broadly following Kuhn’s analysis of theoretical virtues, I suggest that widely shared criteria for pursuit-worthiness function as imprecise, mutually-conflicting values. However, even Kuhn and others sensitive to pragmatic dimensions of theory ‘acceptance’, including the virtue of fruitfulness, still commonly understate the role of pursuit-worthiness—especially by exaggerating the impact of more present-oriented virtues, or failing to stress how ‘competing’ theories excel at addressing different questions or data. This framework clarifies the nature of the choice and competition involved in theory choice, and the role of alternative theoretical virtues. (shrink)

Two questions should be considered when assessing the Kantian dimensions of Kuhn’s thought. First, was Kuhn himself a Kantian? Second, did Kuhn have an influence on later Kantians and neo-Kantians? Kuhn mentioned Kant as an inspiration, and his focus on explanatory frameworks and on the conditions of knowledge appear Kantian. But Kuhn’s emphasis on learning; on activities of symbolization; on paradigms as practical, not just theoretical; and on the social and community aspects of scientific research as constitutive of scientific reasoning, (...) are all outside the Kantian perspective. Kuhn’s admiration for Kant is tempered by his desire to understand the processes of learning, of initiation into a scientific community, of experimentation using instruments, and of persuasion, drawing on the work of familiar influences, including Piaget, Koyré, and Wittgenstein, and less familiar ones, including Langer, Demos, and Frank. Both Kuhn and Kant were interested in the question: what is the status of science, and what is the role of the scientist in its development and justification? But Kuhn presents science in a much more messy, historically contingent, and socially charged way than Kant does. The paper’s conclusion evaluates Kuhn’s reception among researchers including Richardson and Friedman, assessing the prospects for future work. (shrink)

In The Structure of Scientific Revolutions, Thomas Kuhn resorts to concepts from several disciplines in order to describe the general patterns of scientific development. This blend of disciplines can be explained in part by Kuhn's intellectual path, from physics to history and then to philosophy of science; but it also points to a deeper methodological problem, which is the question of what is the real unity of analysis in his model of science. The primary intention of this article is, thus, (...) to give a solution to this difficulty. The answer, I believe, rests on identifying three fundamental units present in Kuhn's theory of scientific development. They are, respectively, the individual, responsible for producing evidence, spreading information, and choosing theories; the community, a set of scientists investigating a series of phenomena; and the groups, individuals with similar behavior but with looser institutional or social ties — a usually neglected category in Kuhnian literature, but equally fundamental for the final outcome of scientific debates. After investigating these categories in detail, I propose a way of integrating them into a general model for explaining the resolution of scientific controversies. Finally, I try to resolve the apparent conflict among disciplinary vocabularies by offering an account of the function of sociological, psychological, and epistemological concepts for describing controversies, and some of the methodologies appropriate for each of these tasks. (shrink)

In his mature works, Kuhn abandons the concept of a paradigm and becomes more interested in the analysis of the conceptual structure of scientific theories. These changes are interpreted as resulting from a ‘linguistic turn’ that Kuhn underwent sometimes around the 1980s. Much of the philosophical discussions about Kuhn’s post-‘linguistic turn’ philosophy revolves around his views on taxonomic concepts. Apart from taxonomy, however, the mature Kuhn introduces other concepts, such as conceptual networks and lexicons. This article distinguishes these three concepts (...) and shows that adopting each one of them has different impacts on Kuhn’s model of science. After distinguishing and assessing the concepts of taxonomy, network, and lexicon, it will be argued that the latter not only fits the Kuhnian model of science better, but it also helps capture the wide sense of Kuhn’s early concept of a paradigm. (shrink)

In the past few years, social epistemologists have developed several formal models of the social organisation of science. While their robustness and representational adequacy has been analysed at length, the function of these models has begun to be discussed in more general terms only recently. In this article, I will interpret many of the current formal models of the scientific community as representing the latest development of what I will call the ‘Kuhnian project’. These models share with Kuhn a number (...) of questions about the relation between individuals and communities. At the same time, they also inherit some of Kuhn’s problematic characterisations of the scientific community. In particular, current models of the social organisation of science represent the scientific community as essentially value-free. This may put into question both their representational adequacy and their normative ambitions. In the end, it will be shown that the discussion on the formal models of the scientific community may contribute in fruitful ways to the ongoing debates on value judgements in science. (shrink)

Scientific progress is one of the topics that has always been considered in the philosophy of science and various accounts have been presented as regards the occurrence of progress. One of the most important challenges in progress is the radical changes in scientific theories, i.e. scientific revolutions. Kuhn considers these revolutions to be discontinuities in the history of science. Although he acknowledges progress in the normal science period by referring to the puzzle solving, he fails to explain the progress in (...) scientific revolutions by proposing the incommensurability of paradigms. In contrast, Bhaskar by describing the stratified world, considers science as a continuous process with the aim of achieving causal mechanisms and structures, discovers and describes new and deeper layers. He explains progress on this basis and believes that science has the potentiality of both change and progress. The present essay discusses the progress theories offered by Bhaskar and Kuhn. Also we compare the epistemological and ontological aspects of these perspectives in order to investigate Khun's inability to explain progress during the revolution in the light of Bhaskar's views. (shrink)

For Kuhn, there are a number of values which provide scientists with a shared basis for theory-choice. These values include accuracy, breadth, consistency, simplicity and fruitfulness. Each of these values may be interpreted in different ways. Moreover, there may be conflict between the values in application to specific theories. In this short paper, Kuhn's idea of scientific values is extended to the value of academic freedom. The value of academic freedom may be interpreted in a number of different ways. Moreover, (...) there are other values which play a role in the functioning of our academic institutions. As with the possible conflict between scientific values, there may be conflict among the academic values. (shrink)

The analytical notions of ‘thought style’, ‘paradigm’, ‘episteme’ and ‘style of reasoning’ are some of the most popular frameworks in the history and philosophy of science. Although their proponents, Ludwik Fleck, Thomas Kuhn, Michel Foucault, and Ian Hacking, are all part of the same philosophical tradition that closely connects history and philosophy, the extent to which they share similar assumptions and objectives is still under debate. In the first part of the paper, I shall argue that, despite the fact that (...) these four thinkers disagree on certain assumptions, their frameworks have the same explanatory goal – to understand how objectivity is possible. I shall present this goal as a necessary element of a common project -- that of historicising Kant's a priori. In the second part of the paper, I shall make an instrumental use of the insights of these four thinkers to form a new model for studying objectivity. I shall also propose a layered diagram that allows the differences between the frameworks to be mapped, while acknowledging their similarities. This diagram will show that the frameworks of style of reasoning and episteme illuminate conditions of possibility that lie at a deeper level than those considered by thought styles and paradigm.

While classical neo-positivists reject any role for traditionally understood values in science, Kuhn identifies five specific values as criteria for assessing a scientific theory; this approach has been further developed by several other authors. This paper focuses on Helen Longino, who presents a significant contemporary critique of Kuhn’s concept. The most controversial aspect of Longino’s position is arguably her claim that the criterion of empirical adequacy is the least defensible basis for assessing theories. The de-emphasizing of the importance of external (...) consistency as a value and the introduction of socio-political considerations into the processes of an assessment of scientific theories are also considered problematic issues. I provide arguments against Longino’s conception, identify some of its problems, and argue for refusal of her approach. (shrink)

The Structure of Scientific Revolution is the famous work by Thomas Kuhn which challenged traditional understanding of science and philosophy of science. His research activities are wide-ranging; central to his notion of incommensurability are the ideas of meaning variance and lexicon, and the impossibility of translation of terms across different theories. It is closely related to the linguistic analysis of scientific language. The schematic nature of Kuhn’s work and his ongoing clarification of its key concepts fostered additional problems of understanding, (...) interpretation, and attribution. This paper analyses the notion of scientific language in the context of incommensurability with special reference to the theory of meaning. Linguistic experts have not attempted to incorporate Kuhn’s incommensurability to address the issues related to epistemology. This Paper shows how Kuhn’s theory of incommensurability can be applied to linguistics to overcome the problems that arise due to similar lexical terms. It argues that Kuhn’s epistemological analysis of incommensurability, particularly the challenge of understanding the process of symbolization in scientific theories, when applied to linguistics can revolutionize the discipline itself which fills the existing knowledge gap. (shrink)

Scientific specialties are the key unit of analysis in Kuhn’s theory of scientific change. Kuhn believed that scientific specialties, in their normal phases, are characterized by theoretical monism. This is what makes scientists so efficient in realizing their epistemic goals. Recent work in the philosophy of scientific practice raises questions about the extent to which there is or needs to be consensus in science, thus challenging a key dimension of Kuhn’s view. Hasok Chang has been a leader in this project, (...) focusing attention on the benefits of pluralism. I argue that Chang and other pluralists are overcorrecting. I argue that a variety of types of pluralism can be reconciled with theoretical monism, and that theoretical monism serves significant functions, aiding scientists in the effective pursuit of their epistemic goals. Thus, I aim to set limits to pluralism. I argue that Kuhn’s theoretical monism not only has room for the sort of pluralism that Chang and others aims to defend, I also show that it presupposes such forms of pluralism. (shrink)

This Introduction provides a rationale for a collection of new paper on Thomas Kuhn. Scholarship on Kuhn has changed dramatically in the last 20 years for numerous reasons. First, scholars studying Kuhn no longer focus narrowly on Structure of Scientific Revolutions. Scholars have been giving careful consideration to Kuhn’s later work. Second, many scholars have been drawing on the vast unpublished resources at the Thomas S. Kuhn Archive at MIT. Third, with the 50th anniversary of the publication of Structure in (...) 2012, there were quite a number of conferences held which led to the publication of a number of volumes reflecting on Kuhn’s impact in philosophy and history of science. These three developments have contributed significantly to our collective understanding of Kuhn and his theories of scientific change and scientific knowledge. Though Kuhn’s position in the philosophy of science can be difficult to gauge, by objective measures Kuhn’s impact is undeniable. Kuhn’s influence outside philosophy of science is also astounding, especially in the social sciences. So it is beyond dispute that Kuhn has had a profound and wide-ranging impact on scholarship.

Thomas Kuhn was never a player in the contemporary realism/anti-realism debates, the debate that gained momentum around 1980 or so, with the publication of Bas van Fraassen’s Scientific Image and Larry Laudan’s “Confutation of Convergent Realism”. But I argue that Kuhn had a significant influence on these debates. Kuhn played a significant role in focusing philosophers’ attention on a different issue than the focus of the realism/anti-realism debate of the 1950s and 1960s. Instead of focusing on the meaning of theoretical (...) terms, philosophers of science turned their attention to the problems raised by changes of theory. The particular shape of the contemporary debate thus owes something to the publication of Structure of Scientific Revolutions. (shrink)

Thomas Kuhn’s The Structure of Scientific Revolutions offers an insightful and engaging theory of science that speaks to scholars across many disciplines. Though initially widely misunderstood, it had a profound impact on the way intellectuals and educated laypeople thought about science. K. Brad Wray traces the influences on Kuhn as he wrote Structure, including his ‘Aristotle epiphany’, his interactions, and his studies of the history of chemistry. Wray then considers the impact of Structure on the social sciences, on the history (...) of science, and on the philosophy of science, where the problem of theory change has set the terms of contemporary realism/anti-realism debates. He examines Kuhn’s frustrations with the Strong Programme sociologists’ appropriations of his views, and debunks several popular claims about what influenced Kuhn as he wrote Structure. His book is a rich and comprehensive assessment of one of the most influential works in the modern sciences. (shrink)

One of the main purposes of science is to explain natural phenomena by increasing our understanding of the physical world and to make predictions about the future based on these explanations. In this context, scientific theories can be defined as large-scale explanations of phenomena. In the historical process, scientists have made various choices among the theories they encounter at the point of solving the problems related to their fields of study. This process, which can be called ‘theory choice’, is one (...) of the most debated issues in the field of philosophy of science in the twentieth century, because this discussion is a very comprehensive problem because it includes important issues such as the use of logical arguments and the determination of the scientific method. At the point of solving this problem, members of the Vienna Circle and Karl Popper think that an objective criterion can be determined by which scientists can apply for theory choice. While the Vienna Circle emphasizes that the best-confirmed theory should be chosen among competing theories, Popper states that competing theories or theories should be tested ruthlessly with appropriate methods, and that successful or corroborated theories should be selected as a result of these tests. Contrary to these views Kuhn states that there are some non-obligatory subjective elements that scientists should follow at the point of theory choice. Accordingly, in this study, the problem of how scientists make their choices among competing theories will be discussed by highlighting Kuhn’s arguments regarding the subjective nature of theory selection.

Bilime ve onun bilgisine akademik, politik, ekonomik ve kamusal alanlar olmak üzere birçok alanda diğer bilgi iddialarına kıyasla daha fazla güven duyulmaktadır. Bilime duyulan bu güvenin temelinde büyük ölçüde bilimsel süreçlerin ve yöntemlerin nesnel bir şekilde yürütülmesi ve bu nesnel sürecin bir ürünü olarak bilimsel bilginin tarafsız bilim insanları tarafından ortaya konulduğu düşüncesi yatmaktadır. Bu bakımdan toplum tarafından bilimin tartışılmaz statüsünün ve bilimsel bilgiye verilen değerin belirleyicisi olarak nesnellik özelliği ön plana çıkmaktadır. Bilhassa doğa bilimleri söz konusu olduğunda bilimsel yöntemin (...) olgulara ve dış dünyaya ilişkin nesnel bilgiler sağladığı düşünülmektedir. Bu bakımdan doğa bilimleri, bilimde nesnelliğin paradigmatik örnekleri olarak kabul görmektedir. Beşeri ve sosyal bilimler alanında ise doğa bilimlerine kıyasla nesnellik algısı düşük olmasına rağmen, yöntemlerinin bilimsel yöntemle çalışılmaya uygun olmasından dolayı en azından ilke olarak nesnel olduğu değerlendirilmektedir. Bilimin değerler alanından ziyade olgu alanına ilişkin çalışmalar yürütmesi, bilim insanlarının değerler, anlamlar ve ideallerinden de kendisini izole ederek bilimsel nesnelliği temin edilebileceği konusunda genel bir kavrayışa yol açmaktadır. Bu görüşün önde gelen düşünürü Karl Popper’dır. Popper bilimsel nesnelliğin, olgusal içerikli önermelerin – protokol önermeleri – öznelerarası sınanabilir olması ile temin edilebileceğini ve böylece bilim insanlarının çalışmalarında kültür, değer ve inanç gibi öznel kanılarının bilimsel bilginin temellendirilmesi ve sınanması noktasında kullanılamayacağını ifade etmiştir. Ancak bilimin doğasına yönelik bir soruşturma bilimsel bilginin düşünüldüğü kadar nesnel bir sürece sahip olmadığını, bilim faaliyetini gerçekleştiren bilim insanlarının kişisel çıkarlarının, değerlerinin ve içinde yaşamış oldukları kültürel faktörlerin bilimsel bilginin elde edilmesi sürecinde etkili olabileceğini ortaya koymaktadır. Bu bakımdan bilimin doğasını doğru bir şekilde anlayabilmenin yolu bilimlerde nesnellik ölçütünün sosyolojik ve kültürel unsurlarla yakından ilişkili olduğunu bilmekten geçmektedir. Thomas Kuhn bilimsel değerlendirmelerde değer yargılarının ve kültürel unsurların kaçınılmaz olduğu düşüncesindedir. Kuhn, Popper’ın aksine sosyolojik etmen ve değerleri de işin içerisine katarak bir bilimsel nesnellik değerlendirmesi yapmaktadır. Bu doğrultuda, o bilimde fazlasıyla öznel unsurları vurguladığı eleştirilerine imkân vermeyecek şekilde bilim insanlarının takip etmesi gereken ve tavsiye niteliğinde olan belirli değerler neticesinde bilimsel nesnelliğin ve rasyonalitenin sağlanabileceğini ifade etmektedir. Bu kapsamda çalışmada, bilimin en bilinen özelliği olarak göze çarpan nesnellik kavramı ve düşüncesine yönelik kavramsal bir belirlemenin ardından kültür ve değer gibi sosyolojik unsurların bilimsel objektifliğin ayrılmaz bir parçası olduğu argümanı, Popper ve Kuhn’un çalışmaları göz önünde bulundurularak serimlenecektir.

“Bilimsel Devrimlerin Yapısı” adlı kitabıyla Thomas Kuhn'un bilim felsefesi çalışmalarında yeni bir çığır açtığı bilinmektedir (Öztürk, 2012: 171). Bu çalışma, Kuhn’un “Bilimsel Devrimlerin Yapısı (The Structure of Scientific Revolutions)” adlı eseri başta olmak üzere, bu eser üzerine yapılan çeşitli çalışmalar referans alınarak sunulmaktadır. Tüm bu çalışmalarda bilimin ilerleme tarzının ele alındığı, fakat bilimin ilerleme tarzı hakkında farklı sıralamaların yer aldığı görülmektedir. Bu çalışmanın amacı, bilimin ilerleme tarzı hakkında daha önce ele alınanlardan farklı bir sıralama sunmaktır. Ulaşılan bu farklı sıralama ile (...) Kuhn’un anlaşılır kılınması mümkün olabilecektir. Çalışmanın amacı doğrultusunda, bilimin ilerleme tarzı hakkında farklı bir sıralama sunarak beş aşamalı bir sıralama ortaya konulacak olup, literatüre de bir katkı sağlanmaktadır. Sıralamaya ilişkin aşamalar, olağan bilim öncesi dönem (paradigma öncesi), olağan bilim dönemi (paradigma ve bilmece), bunalım dönemi (bilimsel kuramların ortaya çıkması), bilimsel devrim dönemi (olağanüstü araştırma ve olağanüstü bilim) ve bilimsel devrim sonrası dönem (yeni paradigma ve yeni olağan bilim) olarak ayrı ayrı ve detaylı bir şekilde incelenmektedir.

In recent years, the full text of papers are increasingly available electronically which opens up the possibility of quantitatively investigating citation contexts in more detail. In this study, we introduce a new form of citation analysis, which we call citation concept analysis (CCA). CCA is intended to reveal the cognitive impact certain concepts—published in a highly-cited landmark publication—have on the citing authors. It counts the number of times the concepts are mentioned (cited) in the citation context of citing publications. We (...) demonstrate the method using three classical highly cited books: (1) The structure of scientific revolutions by Thomas S. Kuhn, (2) The logic of scientific discovery—Logik der Forschung: Zur Erkenntnistheorie der modernen Naturwissenschaft in German—, and (3) Conjectures and refutations: the growth of scientific knowledge by Karl R. Popper. It is not surprising—as our results show—that Kuhn’s “paradigm” concept seems to have had a significant impact. What is surprising is that our results indicate a much larger impact of the concept “paradigm” than Kuhn’s other concepts, e.g., “scientific revolution”. The paradigm concept accounts for about 40% of the concept-related citations to Kuhn’s work, and its impact is resilient across all disciplines and over time. With respect to Popper, “falsification” is the most used concept derived from his books. Falsification is the cornerstone of Popper’s critical rationalism. (shrink)

Picking up on John Forrester’s disclosure that he felt ‘haunted’ by the suspicion that Thomas Kuhn’s interests had become his own, this essay complexifies our understanding of both of their legacies by presenting two sites for that haunting. The first is located by engaging Forrester’s argument that the connection between Kuhn and psychoanalysis was direct. However, recent archival discoveries suggest that that is incorrect. Instead, Kuhn’s influence in this regard was Jean Piaget. And it is Piaget’s thinking that was influenced (...) directly by psychoanalysis. Psychoanalysis then haunts Kuhn’s thinking through Piaget, and thus Piaget haunts Forrester through Kuhn. To better understand this second site of the haunting—which is ultimately the more important one, given the intent of this special issue—Piaget’s early psychoanalytic ideas are uncovered through their interaction with his early biology and subsequent turn to philosophy. But several layers of conflicting contemporary misunderstandings are first excavated. The method of hauntology is also developed, taking advantage of its origins as a critical response to the psychoanalytic discourse. As a result of adopting this approach, a larger than usual number of primary sources have been unearthed and presented as evidence. Where those influences have continued to have an impact, but their sources forgotten, they have thus been returned. They can then all be considered together in deriving new perspectives of Forrester’s cases/Kuhn’s exemplars/Piaget’s stages. (shrink)

Recent work in the history of philosophy of science details the Kantianism of philosophers often thought opposed to one another, e.g., Hans Reichenbach, C.I. Lewis, Rudolf Carnap, and Thomas Kuhn. Historians of philosophy of science in the last two decades have been particularly interested in the Kantianism of Reichenbach, Carnap, and Kuhn, and more recently, of Lewis. While recent historical work focuses on recovering the threatened-to-be-forgotten Kantian themes of early twentieth-century philosophy of science, we should not elide the differences between (...) the Kantian strands running throughout this work. In this paper, I disentangle a few of these strands in the work of Reichenbach and Lewis focusing especially on their theories of relativized, constitutive a priori principles in empirical knowledge. In particular, I highlight three related differences between Reichenbach and Lewis concerning their motivations in analyzing scientific knowledge and scientific practice, their differing conceptions of constitutivity, and their relativization of constitutive a priori principles. In light of these differences, I argue Lewis’s Kantianism is more similar to Kuhn’s Kantianism than Reichenbach’s, and so might be of more contemporary relevance to social and practice-based approaches to the philosophy of science.

This study investigates Thomas Kuhn’s philosophy that had broad influence in philosophy of science by his book The Structure of Scientific Revolutions, and the contributions of his philosophy to Turkish philosophical literature. Kuhnian part of the picture of science debates brings to light considering the works done in Turkey upon the philosophy of Kuhn. In the first part of the thesis, T. Kuhn's life and works are mentioned. The second part focuses on Kuhn's philosophy of science and the concept of (...) paradigm.

According to Kuhn’s account of the nature of scientific paradigms, how one experiences the world varies drastically from one context to another depending on the accepted paradigm of the context in question. In other words, one’s pre-existing conceptual structure concerning the world not only acts as an epistemological framework for its possible understanding, but also fundamentally affects the phenomenological observations of the world as something; this latter function of the conceptual structure motivates the view that mature scientific paradigms/theories and the (...) data of scientific observation/experimentation are essentially two sides of the same coin. What is interesting, then, is that even between different historical eras that generally regarded the world in clearly incompatible ways, albeit still informed by paradigms, Kuhn still attributes scientific knowledge to each. To make sense of this, the explanatory resources of epistemological contextualism are used to specify potentially one way in which epistemic standards for knowledge must change between different historical eras for one to justifiably claim scientific knowledge within these different contexts. As we shall see, the argument for Kuhn’s account of paradigm being contextualist in character is apparently best made through the notion of doubt-driven context-shifts as actualising change in the form of P between different contexts in which “S knows that P” is asserted. As such, this paper first explores Kuhn’s account of scientific knowledge and paradigms before considering how the account can be considered contextualist in nature. Moreover, other context-concerned systems, such as Traditional, and Subject-Sensitive Invariantism, are briefly investigated to substantiate claims of what cannot be accurately ascribed to Kuhn’s epistemology.

The concept of “paradigm” became widely known with Thomas Kuhn’s book The Structure of Scientific Revolutions. From there on, paradigms started being employed in the most diverse fields and situations. Curiously, though, the popularity of the term went hand in hand with an enormous vagueness in its application: numerous meanings were attributed to this concept and different things were claimed to be paradigms. The main reason for the lack of agreement regarding the notion and the use of paradigm was the (...) absence of a detailed description and analysis of a concrete paradigm in Kuhn’s book—especially, one coupled with a discussion that could contrast paradigms to other epistemic objects, such as “theories.” The aim of this article is to fill this gap. First, I briefly examine the notion of paradigm, stressing its core meaning as that of “exemplar.” Next, I analyze a specific case in economics, indicating the features that make it a paradigm: (i) the fact that it is an example not reducible to an axiomatizable theory, and (ii) that this example is constitutive of normal science.

Relativism in the philosophy of science is widely associated with the work of Thomas Kuhn and Paul Feyerabend. Kuhn and Feyerabend espoused views about conceptual change and variation of scientific method that have apparent relativistic implications. Both held that scientific theories or paradigms may be incommensurable due to semantic variation. Two ways that truth may be relative because of semantic incommensurability will be distinguished. Davidson’s criticism of the idea of an untranslatable language will be discussed, as well as a response (...) to incommensurability based on the causal theory of reference of Kripke and Putnam. A form of relativism with respect to epistemic rationality may also be derived from the claims of Kuhn and Feyerabend about methodological variation. Kuhn’s initial suggestions about paradigm-dependent standards and absence of extra-paradigmatic standards give rise to a view on which rationality is relative to paradigm. Kuhn’s later view that there is a stable set of shared scientific values is less prone to relativistic interpretation. Feyerabend’s claim that “anything goes” suggests an extreme form of relativism, but should be understood instead as the view that all rules of method may be violated in some circumstances. The latter brings Feyerabend’s view into line with Kuhn’s later view. (shrink)

Alexander Bird indicates that the significance of Thomas Kuhn in the history of philosophy of science is somehow paradoxical. On the one hand, Kuhn was one of the most influential and important philosophers of science in the second half of the twentieth century. On the other hand, nowadays there is little distinctively Kuhn’s legacy in the sense that most of Kuhn’s work has no longer any philosophical significance. Bird argues that the explanation of the paradox of Kuhn’s legacy is that (...) Kuhn took a direction opposite to that of the mainstream of the philosophy of science in his later academic career. This paper aims to provide a new way to understand and develop Kuhn’s legacy by revisiting the development of Kuhn’s philosophy of science in 1970s and proposing a new account of exemplar. Firstly, I propose my diagnosis of Kuhn’s “wrong turning” by identifying Kuhn’s two novel contributions: the introduction of paradigm and the proposal of the incommensurability thesis. Secondly, I argue that Kuhn made a conceptual/terminological turn from paradigm to theory, which undermined Kuhn’s novel contributions. Thirdly, I propose a new articulation of exemplar and propose an exemplar-based approach to analysing the history of science. Finally, I show how the exemplar-based approach can be applied to analyse the history of science by my case study of the early development of genetics. (shrink)

Following the publication of Thomas Kuhn’s Structure of Scientific Revolutions the term paradigm became ubiquitous. It is now commonplace in academic writing across the disciplines. Though much has been written about Kuhn’s use of the term and its impact on other fields, there has not yet been a systematic study of how frequently Kuhn used the term in Structure. My aim in this paper is to provide such an analysis. I aim to answer the following questions: (1) How many times (...) does Kuhn actually use the term in the book?; (2) What is the most number of times that he uses the term on a single page?; and (3) Is the term used evenly throughout the book or is it mentioned more often in some chapters than in others?

In his account of scientific revolutions, Thomas Kuhn suggests that after a revolutionary change of theory, it is as if scientists are working in a different world. In this paper, we aim to show that the notion of world change is insightful. We contrast the reporting of the discovery of neon in 1898 with the discovery of hafnium in 1923. The one discovery was made when elements were identified by their atomic weight; the other discovery was made after scientists came (...) to classify elements by their atomic number. By considering two instances of the reporting of the discovery of a new chemical element 25 years apart, we argue that it becomes clear how chemists can be said to have been responding to different worlds as a result of the change in the concept of a chemical element. They saw, did, and reported different things as they conducted their research on the new chemical elements. (shrink)

In Part I of “Of Miracles,” Hume argues that belief in miracle-testimony is never justified. While Hume’s argument has been widely criticized and defended along a number of different veins, including its import on scientific inquiry, this paper takes a novel approach by comparing Hume’s argument with Thomas Kuhn’s account of scientific anomalies. This paper makes two arguments: first that certain types of scientific anomalies—those that conflict with the corresponding paradigm theory—are analogous to miracles in the relevant ways. Note, importantly, (...) that the argument applies only to the first definition of ‘miracle’ that Hume offers Second, it argues that we are sometimes rationally justified in believing testimony for scientific anomalies, because there have been several cases of scientists accepting such anomalies and—assuming certain criteria are met—we are rationally justified in believing these scientists. If both arguments are successful, then it is possible to be rationally justified in believing miracle-testimony, though the extent of justification depends on various criteria and comes in degrees. After examining a few objections, the paper concludes by contextualizing this argument in relation to Part II of Hume’s essay and in relation to broader apologetic concerns. In short, it is vital to recognize that this paper’s focus is Hume’s first account of ‘miracle,’ rather than his argument against miracle-testimony more broadly, but the argument could be coupled with other arguments against Hume’s broader attack on miracle-testimony.

According to a widespread view, Thomas Kuhn’s model of scientific development would relegate rationality to a second plane, openly flirting with irrationalist positions. The intent of this article is to clarify this aspect of his thinking and refute this common interpretation. I begin by analysing the nature of values in Kuhn’s model and how they are connected to rationality. For Kuhn, a theory is chosen rationally when: i) the evaluation is based on values characteristic of science; ii) a theory is (...) considered better the more it manifests these values; and iii) the scientist chooses the best-evaluated theory. The second part of this article deals with the thesis of the variability of values. According to Kuhn, the examples through which epistemic values are presented vary for each person, and for this reason individuals interpret these criteria differently. Consequently, two scientists, using the same values, can come to a rational disagreement over which theory to choose. Finally, I point out the limitations of this notion of rationality for the explanation of consensus formation, and the corresponding demand for a sociological theory that reconnects individual rationality with convergence of opinions.
