El año 1962 vio la introducción, por parte de Kuhn y Feyerabend, de la tesis de la inconmensurabilidad de las teorías científicas . Desde entonces, la tesis ha sido debatida ampliamente y ha atraído muchos críticos. Su influencia aún es considerable, particularmente en las áreas de la historia y la filosofía de la ciencia interesadas en el cambio y la elección de teorías. Esta influencia se debe, en gran medida, a la inmensa popularidad de la obra maestra de Kuhn, La (...) Estructura de las revoluciones científicas, la cual asegura que la idea de la inconmensurabilidad continúe alcanzando un público amplio. Sin embargo, no es tan ampliamente apreciado que la versión de Kuhn de la inconmensurabilidad ha ido sufriendo, con el tiempo, un proceso continuo de revisión y clarificación. Como resultado de esto, la versión de la tesis por la que Kuhn es mejor conocido difiere notablemente de la versión que él asume en el presente. En este artículo presento un estudio del proceso de cambio, caracterizando las etapas principales por las que transcurre el concepto kuhniano de inconmensurabilidad. (shrink)

The history of developmental biology is interwoven with debates as to whether mechanistic explanations of development are possible or whether alternative explanatory principles or even vital forces need to be assumed. In particular, the demonstrated ability of embryonic cells to tune their developmental fate precisely to their relative position and the overall size of the embryo was once thought to be inexplicable in mechanistic terms. Taking a causal perspective, this Element examines to what extent and how developmental biology, having turned (...) molecular about four decades ago, has been able to meet the vitalist challenge. It focuses not only on the nature of explanations but also on the usefulness of causal knowledge – including the knowledge of classical experimental embryology – for further scientific discovery. It also shows how this causal perspective allows us to understand the nature and significance of some key concepts, including organizer, signal and morphogen.

Thomas Kuhn, dans la Structure des révolutions scientifiques, décrit les révolutions scientifiques comme des changements dans la vision scientifique du monde. Or, ce changement de vision du monde semble trouver une partie de ses racines dans la psychologie des formes. La Gestaltpsychologie a permis de remettre en cause certaines conceptions classiques de la psychologie issues de l’empirisme du xviiie siècle et par là même de penser les changements de perception non comme des changements d’interprétation, mais comme des renversements d’une structure (...) à une autre. Ces changements visuels de forme sont particulièrement bien exemplifiés dans les figures ambiguës sur lesquelles Kuhn s’appuie pour analyser le passage d’un paradigme à autre, bien que les gestaltistes, comme Köhler, aient rejeté l’hypothèse selon laquelle il serait possible de « voir » directement une signification. Reste à savoir si ces Gestalt-switches ne concernent pas davantage les historiens des sciences que les scientifiques eux-mêmes. (shrink)

Kuhn's alleged taxonomic interpretation of incommensurability is grounded on an ill defined notion of untranslatability and is hence radically incomplete. To supplement it, I reconstruct Kuhn's taxonomic interpretation on the basis of a logical-semantic theory of taxonomy, a semantic theory of truth-value, and a truth-value conditional theory of cross-language communication. According to the reconstruction, two scientific languages are incommensurable when core sentences of one language, which have truth values when considered within its own context, lack truth values when considered within (...) the context of the other due to the unmatchable taxonomic structures underlying them. So constructed, Kuhn's mature interpretation of incommensurability does not depend upon the notion of truth-preserving translatability, but rather depends on the notion of truth-value-status-preserving cross-language communication. The reconstruction makes Kuhn's notion of incommensurability a well grounded, tenable and integrated notion.Author Keywords: Incommensurability; Thomas Kuhn; Taxonomic structures; Lexicons; Truth-value; Untranslatability; Cross-language communication.

SummaryIn the 1940s a controversy developed between John H. Northrop (Nobel Laureate, 1946) and Max Delbrück (Nobel Laureate, 1969) on the formation of bacteriophage. From the historiography of molecular biology there emerges a picture of an obstinate Northrop who repudiated the ‘correct’ insights revealed by the experiments of Delbrück. The established reputation of Northrop confronts one with the question of why Delbrück's epoch-making experiments were not convincing for Northrop. It will be argued that this was a consequence of local incommensurability (...) between Northrop's physiological/chemical research style and Delbrück's bacteriological/genetic research style. The analysis of this controversy reveals the elements that made up these two research styles. (shrink)

In this article, Thomas Kuhn’s theory of incommensurable paradigms learned through exemplars is discussed as a theory of acculturation akin to those of cultural anthropology. Yet his hermeneutic approach results in a classic problem, referred to here as the paradox of objective relativism. A solution, at least for observers of contemporary cultures, is drawn from Kuhn’s own writings: a fieldwork method of “going native.” It is argued that Kuhn’s views are as important a corrective for anthropologists studying native systems of (...) knowledge as they have been for philosophers and sociologists of science. The epistemological and disciplinary implications of such a methodology are discussed. (shrink)

Whereas there is much discussion about Thomas Kuhn’s notion of methodological incommensurability and many have seen his ideas as an attempt to allow for rational disagreement in science, so far no serious analysis of how exactly Kuhn aims to account for rational disagreement has been proposed. This paper provides the first in-depth analysis of Kuhn’s account of rational disagreement in science—an account that can be seen as the most prominent attempt to allow for rational disagreement in science. Three things will (...) be shown: First, we find not one, but two accounts of rational disagreements in science in Kuhn’s writings: one stemming from methodological incommensurability and one stemming from Kuhn-underdetermination, which are not only fundamentally different—the first purports to explain how disagreeing scientists can nevertheless be rational, while the second attempts to show how rational scientists can nevertheless disagree—but appear to be incompatible with each other. Second, I will assess both accounts. Kuhn’s account from methodological incommensurability is not convincing since it cannot explain rational disagreement in science. Whereas, on the other hand, Kuhn’s account from Kuhn-underdetermination allows for rational disagreement, his argument why we should accept it is not convincing. Third, I present a tentative sketch of an alternative to Kuhn’s account that emphasizes the fallibility of epistemic justification in order to show that Kuhn’s argument founders. In sum, the paper shows that focusing not on the muchly debated consequences of methodological incommensurability, but on Kuhn’s treatment of rational disagreement gives new insight into the adequate interpretation of his thought as well as the cogency of his ideas.

Since 1962 Kuhn's concept of incommensurability has undergone a process of transformation. His current account of incommensurability has little in common with his original account of it. Originally, incommensurability was a relation of methodological, observational and conceptual disparity between paradigms. Later Kuhn restricted the notion to the semantical sphere and assimilated it to the indeterminacy of translation. Recently he has developed an account of it as localized translation failure between subsets of terms employed by theories.

Mucho se ha escrito para analizar y dar sentido a dos términos que vienen intrínsecamente unidos, el nacionalismo y la nación. La principal consecuencia positiva de esto ha sido un vasto debate teórico sobre el nacionalismo y la nación que indudablemente los enriquece. La principal consecuencia negativa, por su parte, es que el desarrollo del propio debate, y cómo se ha ido formando, ha recibido poca atención. El objetivo de este artículo es exponer cómo este debate se ha sido desarrollado (...) alrededor de los cuatros paradigmas clásicos del nacionalismo. Para ello, se aplica el esquema kuhniano para saber cuándo, cómo, y por qué se articularon estos paradigmas clásicos en torno a estos dos términos. Con esto se pretende profundizar en la explicación histórica de Moreno Almendral (2015), pero desde la filosofía de la ciencia, desarrollando una visión mucho más detallada del debate en torno al nacionalismo y la nación.

Thomas Kuhn is mostly known for his contributions to the philosophy of science. However, it was chiefly to investigations in philosophy of language that he dedicated the last part of his career. The aim of this paper is to present a systematic view of Kuhn’s main ideas on this subject. I start by describing his theory of concept, in particular what he says about kind terms. Such terms, acquired in blocks that form contrast sets or “taxonomies,” are learned through ostensible (...) definitions. Next, I analyze Kuhn’s concepts of “meaning” and “truth.” Finally, I discuss a second type of kinds terms, not fully investigated by him, which is learned together with scientific laws. Resumo Thomas Kuhn é conhecido principalmente por suas contribuições para a filosofia da ciência. No entanto, foi em grande medida à filosofia da linguagem que ele dedicou a última parte de sua carreira. O objetivo deste artigo é apresentar uma visão sistemática das principais ideias de Kuhn sobre esse assunto. Começo descrevendo sua teoria do conceito, em particular o que ele diz sobre termos para espécie. Tais termos, aprendidos em blocos que formam conjuntos de contraste ou “taxonomias”, são aprendidos através de definições ostensivas. Em seguida, analiso as concepções de Kuhn de “significado” e “verdade”. Finalmente, discuto um segundo tipo de termo para espécies, não totalmente investigado por ele, que é aprendido junto com as leis científicas. (shrink)

This paper argues that Ludwik Fleck’s concepts of thought collectives and proto-ideas are surprisingly topical to tackle some conceptual challenges in analyzing contemporary innovation. The objective of this paper is twofold: First, it strives to establish Ludwik Fleck as an important classic on the map of innovation analysis. A systematic comparison with Thomas Kuhn’s work on paradigms, a concept highly influential in various branches of innovation studies, suggests a number of pronounced yet under-researched advantages of a Fleckian perspective in the (...) context of technological change and innovation. Secondly, the paper links these advantages to some recent changes in the organization of innovation. Due to the rising pervasiveness of Information and Communication Technologies (ICTs), configurational innovation has become commonplace that cuts across the boundaries of established trajectories of knowledge generation. Fleck’s graded understanding of the closedness of thought collectives and his weak notion of incommensurability provide powerful metaphors to grasp the peculiarities of configurational innovation.

Thomas Kuhn had little to say about scientific change in biological science, and biologists are ambivalent about how applicable his framework is for their disciplines. We apply Kuhn’s account of paradigm change to evolutionary microbiology, where key Darwinian tenets are being challenged by two decades of findings from molecular phylogenetics. The chief culprit is lateral gene transfer, which undermines the role of vertical descent and the representation of evolutionary history as a tree of life. To assess Kuhn’s relevance to this (...) controversy, we add a social analysis of the scientists involved to the historical and philosophical debates. We conclude that while Kuhn’s account may capture aspects of the pattern of an episode of scientific change, he has little to say about how the process of generating new understandings is occurring in evolutionary microbiology. Once Kuhn’s application is limited to that of an initial investigative probe into how scientific problem-solving occurs, his disciplinary scope becomes broader. (shrink)

The purpose of this article is to show that the customary understanding of epistemic progress as a kind of belief change is incomplete and that conceptual change has to be acknowledged as a crucial driving force in epistemic progress. The author’s argument for the epistemological relevance of conceptual change proceeds as follows. First, he develops an account of conceptual change that clearly distinguishes conceptual change from belief change. He then takes a closer look at two kinds of conceptual change that (...) are of special interest from an epistemological point of view. He calls them “disclosing” conceptual change and “revisionary” conceptual change. He then shows that the idea of epistemic value that demarcates the realm of epistemological inquiry applies to concepts and conceptual change. (shrink)

This paper draws a connection between recentdevelopments in naturalized philosophyof science and the Buchanan research programin economics. Economic approaches innaturalized philosophy of science canbe combined to form an economic philosophy ofscience. After giving an overview of someof these approaches, I lay out the fundamentalsof the Buchanan research program. I arguethat its main elements are a theory of interactionsand a normative foundation in consensus whichhelp to answer some important criticismsof economic philosophy of science.

Up to the introduction of the term and concept of incommensurability by T. S. Kuhn and P. K. Feyerabend in the early 1960s, scientific texts were supposed to pose no problem as regards their translation, unlike literature, which was thought very difficult to translate. After the introduction of the term, translation of scientific language became equally problematic because, due to conceptual and perceptual incommensurability, there was no common observation basis to ground linguistic equivalences between languages of incommensurable paradigms. This article (...) highlights the presuppositions that link incommensurability to dramatic consequences (impossibility of communication, translation, and comparative evaluation of paradigms) and tries to sketch an alternative way of understanding incommensurability and translation drawing on Kuhn’s work. From this perspective, translation is not an all-or-nothing affair for either science or literature and becomes a problem to be solved for each particular set of circumstances. (shrink)

The paper deals with the interrelations between the philosophy, sociology and historiography of science in Thomas Kuhn’s theory of scientific development. First, the historiography of science provides the basis for both the philosophy and sociology of science in the sense that the fundamental questions of both disciplines depend on the principles of the form of historiography employed. Second, the fusion of the sociology and philosophy of science, as advocated by Kuhn, is discussed. This fusion consists essentially in a replacement of (...) methodological rules by cognitive values that influence the decisions of scientific communities. As a consequence, the question of the rationality of theory choice arises, both with respect to the actual decisions and to the possible justification of cognitive values and their change. (shrink)

The paper discusses some aspects of the relationship between Feyerabend and Kuhn. First, some biographical remarks concerning their connections are made. Second, four characteristics of Feyerabend and Kuhn's concept of incommensurability are discussed. Third, Feyerabend's general criticism of Kuhn's Structure of Scientific Revolutions is reconstructed. Forth and more specifically, Feyerabend's criticism of Kuhn's evaluation of normal science is critically investigated. Finally, Feyerabend's re-evaluation of Kuhn's philosophy towards the end of his life is presented.

In this paper, we analyze the debate between the Modern Synthesis and the Extended Evolutionary Synthesis in light of the concept of incommensurability developed by Thomas Kuhn. In order to do so, first we briefly present both the Modern Synthesis and the Extended Evolutionary Synthesis. Then, we clarify the meaning and interpretations of incommensurability throughout Kuhn’s works, concluding that the version of this concept deployed in The Structure of Scientific Revolutions is the best suited to the analysis of scientific disputes. (...) After discussing incommensurability in Kuhn’s works, we address the question of whether the Modern Synthesis and the Extended Evolutionary Synthesis can be considered semantically, methodologically, and ontologically incommensurable, concluding that they can. Finally, we discuss three problems that arise from such a conclusion: firstly, what are the consequences of incommensurability; secondly, which mode of scientific change better explains this current dispute in evolutionary biology; and thirdly, whether rational theory comparison is possible given incommensurability. We suggest that the main consequence of incommensurability is profound disagreement, that the kind of scientific change that better explains the current dispute between the MS and the EES may be scientific specialization, and that incommensurability does not preclude rational theory comparison.

Thirty years after the publication of Thomas Kuhn’s The Structure of Scientific Revolutions, sharp disagreement persists concerning the implications of Kuhn’s "historicist" challenge to empiricism. I discuss the historicist movement over the past thirty years, and the extent to which the discourse between two branches of the historical school has been influenced by tacit assumptions shared with Rudolf Carnap’s empiricism. I begin with an examination of Carnap’s logicism --his logic of science-- and his 1960 correspondence with Kuhn. I focus on (...) problems in the analysis applied to the unit of metascientific study or appraisal, arguing for a reassessment of historicist treatment of the internal/external distinction and historiographic meta-methodology. The critique of objectivism and relativism that eventuates from this re-assessment is a double-edged blade, undercutting both objectivist and relativist treatments of cognitive evaluation and scientific change. I use it to cut across an otherwise diverse group of historicist-influenced writers, including Imre Lakatos, Larry Laudan, H. M. Collins, Stephen Stich. I. Introduction.. (shrink)

In this article, I discuss Gadamer's hermeneutic account of understanding as an alternative to Kuhn's incommensurability thesis. After a brief account of Kuhn's aesthetic account and arguments against it, I argue that the linguistic account faces a paradox that results from Kuhn's objectivist account of understanding, and his lack of historical reflexivity. The statement 'Languages are incommensurable' is not a unique view of language, and is thus subject to contest by incommensurable readings. Resolving the paradox requires an account of incommensurability (...) that is self-referentially consistent, open-ended, and historically reflexive whereby we recognize that our very interest in incommensurability is historically conditioned. By meeting these conditions, Gadamer's account of historical understanding offers a middle ground between two extremes: on the one side is the claim that understanding involves becoming a native of an incommensurable language, and on the other side is the rejection of the prospect of understanding a contextually removed language altogether. Gadamer is discussed as a mediator between Kuhn's epistemic and historical projects, and thus paves the way for a new hermeneutics of science. The notions of traditional horizon, historically effected consciousness, the universality of interpretation, alienation, dialogical openness, and the fusion of horizons are also discussed. (shrink)

Some think that issues to do with scientific method are last century's stale debate; Popper was an advocate of methodology, but Kuhn, Feyerabend, and others are alleged to have brought the debate about its status to an end. The papers in this volume show that issues in methodology are still very much alive. Some of the papers reinvestigate issues in the debate over methodology, while others set out new ways in which the debate has developed in the last decade. The (...) book will be of interest to philosophers and scientists alike in the reassessment it provides of earlier debates about method and current directions of research. (shrink)

A popular rejoinder to the potential threat that incommensurability might pose to scientific realism has been the referential response: despite meaning variance, there can be referential continuity, which is sufficient for rational theory choice. This response has been charged with meta-incommensurability, according to which it begs the question by assuming realist metaphysics. However, realists take it to be a rhetorical device that hinders productive discussion. By reconstructing the debate, this paper aims to demonstrate two things. First, there are unexpected commonalities (...) between realists and non-realists, meaning that the charge of meta-incommensurability is more or less exaggerated. Second, meta-incommensurability, which is to be found in the ways to make sense of referential overlap at the token level, still plays a role in the realism debate. (shrink)

According to the received translational interpretation of incommensurability, incommensurability is viewed as untranslatability due to radical variance of meaning or reference of the terms in two competing scientific languages. The author argues that the translational approach to incommensurability does not effectively clarify the concept of incommensurability. Since it cannot provide us with tenable, integrated concept of incommensurability, it should be rejected.

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.

According to G. E. Moore, moral expertise requires abilities of several kinds: the ability to factor judgments of right and wrong into (a) judgments of good and bad and (b) judgments of cause and effect, (2) the ability to use intuition to make the requisite judgments of good and bad, and (3) the ability to use empirical investigation to make the requisite judgments of cause and effect. Moore’s conception of moral expertise is thus extremely demanding, but he supplements it with (...) some very simple practical guidance. (shrink)

This Ph.D. thesis provides a pilosophical account of the structure of the evolutionary synthesis of the 1930s and 40s. The first, more historical part analyses how classical genetics came to be integrated into evolutionary thinking, highlighting in particular the importance of chromosomal mapping of Drosophila strains collected in the wild by Dobzansky, but also the work of Goldschmidt, Sumners, Timofeeff-Ressovsky and others. The second, more philosophical part attempts to answer the question wherein the unity of the synthesis consisted. I argue (...) that it exemplifies a weak of form of explanatory unification. (shrink)
