Incommensurability between successive scientific theories—the impossibility of empirical evidence dictating the choice between them—was Thomas Kuhn's most controversial proposal. Toward defending it, he directed much effort over his last 30 years into formulating precise conditions under which two theories would be undeniably incommensurable with one another. His first step, in the late 1960s, was to argue that incommensurability must result when two theories involve incompatible taxonomies. The problem he then struggled with, never obtaining a solution that he found entirely satisfactory, (...) was how to extend this initial line of thought to sciences like physics in which taxonomy is not so transparently dominant as it is, for example, in chemistry. This paper reconsiders incommensurability in the light of examples in which evidence historically did and did not carry over continuously from old laws and theories to new ones. The transition from ray to wave optics early in the nineteenth century, we argue, is especially informative in this regard. The evidence for the theory of polarization within ray optics did not carry over to wave optics, so that this transition can be regarded as a prototypical case of discontinuity of evidence, and hence of incommensurability in the way Kuhn wanted. Yet the evidence for classic geometric optics did carry over to wave optics, notwithstanding the fundamental conceptual readjustment that Fresnel's wave theory required. (shrink)

What is it to be scientific? Is there such a thing as scientific method? And if so, how might such methods be justified? Robert Nola and Howard Sankey seek to provide answers to these fundamental questions in their exploration of the major recent theories of scientific method. Although for many scientists their understanding of method is something they just pick up in the course of being trained, Nola and Sankey argue that it is possible to be explicit about what this (...) tacit understanding of method is, rather than leave it as some unfathomable mystery. They robustly defend the idea that there is such a thing as scientific method and show how this might be legitimated. This book begins with the question of what methodology might mean and explores the notions of values, rules and principles, before investigating how methodologists have sought to show that our scientific methods are rational. Part 2 of this book sets out some principles of inductive method and examines its alternatives including abduction, IBE, and hypothetico-deductivism. Part 3 introduces probabilistic modes of reasoning, particularly Bayesianism in its various guises, and shows how it is able to give an account of many of the values and rules of method. Part 4 considers the ideas of philosophers who have proposed distinctive theories of method such as Popper, Lakatos, Kuhn and Feyerabend and Part 5 continues this theme by considering philosophers who have proposed naturalised theories of method such as Quine, Laudan and Rescher. This book offers readers a comprehensive introduction to the idea of scientific method and a wide-ranging discussion of how historians of science, philosophers of science and scientists have grappled with the question over the last fifty years.

In the light of two unpublished letters from Carnap to Kuhn, this essay examines the relationship between Kuhn's The Structure of Scientific Revolutions and Carnap's philosophical views. Contrary to the common wisdom that Kuhn's book refuted logical empiricism, it argues that Carnap's views of revolutionary scientific change are rather similar to those detailed by Kuhn. This serves both to explain Carnap's appreciation of The Structure of Scientific Revolutions and to suggest that logical empiricism, insofar as that program rested on Carnap's (...) shoulders, was not substantially upstaged by Kuhn's book.

Thomas Kuhn's _The Structure of Scientific Revolutions_ is one of the best known and most influential books of the twentieth century. Whether they adore or revile him, critics and fans alike have tended to agree on one thing: Kuhn's ideas were revolutionary. But were they? Steve Fuller argues that Kuhn actually held a profoundly conservative view of science and how one ought to study its history. Early on, Kuhn came under the influence of Harvard President James Bryant Conant, who had (...) developed an educational program intended to help deflect Cold War unease over science's uncertain future by focusing on its illustrious past. Fuller argues that this rhetoric made its way into _Structure,_ which Fuller sees as preserving and reinforcing the old view that science really is just a steady accumulation of truths about the world. Fuller suggests that Kuhn, deliberately or not, shared the tendency in Western culture to conceal possible negative effects of new knowledge from the general public. Because it insists on a difference between a history of science for scientists and one suited to historians, Fuller charges that _Structure_ created the awkward divide that has led directly to the "Science Wars" and has stifled much innovative research. In conclusion, Fuller offers a way forward that rejects Kuhn's fixation on paradigms in favor of a conception of science as a social movement designed to empower society's traditionally disenfranchised elements. Certain to be controversial, _Thomas Kuhn_ must be read by anyone who has adopted, challenged, or otherwise engaged with _The Structure of Scientific Revolutions._ "Structure will never look quite the same again after Fuller. In that sense, he has achieved one of the main aims of his ambitious and impressively executed project."—Jon Turney, _Times Higher Education Supplement_ "Philosophies like Kuhn's narrow the possible futures of inquiry by politically methodizing and taming them. More republican philosophies will leave the future open. Mr. Fuller has amply succeeded in his program of distinguishing the one from the other."—William R. Everdell, _Washington Times_. (shrink)

La Revolución Científica del siglo XVII ha ocupado un lugar central en la historiografía de la ciencia de este siglo. Mitificada en diversos sentidos hasta el siglo XIX, fue negada por parte de P. Duhem, que retrotrae sus principales méritos a la Edad Media cristiana, y afirmada y teorizada por la moderna historiografía de la ciencia que nace con A. Koyré. Esa historiografía rupturista que exige la contextualización de la ciencia en la cultura del momento se desarrolló considerablemente hasta la (...) década de los sesenta, en la que toma conciencia de su importancia teórica tanto en el trabajo de historiador como sobre todo en la filosofía de la ciencia de T. S. Kuhn. El modelo historiográfico desarrollado de Koyré a Kuhn se gestó en buena parte al hilo de las grandes polémicas sobre “continuidad” y “ruptura” por una parte, e “internalismo” y “externalismo” por otra parte. En ambos casos la Revolución científica del siglo XVII ha sido objeto central de reflexión, y el lugar y el papel del Renacimiento en esta Revolución ha sido tema de amplias discusiones que, en definitiva, tienen que ver con la naturaleza de la ciencia. Pero en las últimas décadas el modelo historiográfico desarrollado de Koyré a Kuhn ha sido desafiado por los sociólogos de la ciencia que han reestructurado el debate internalismo-externalismo. Esos desarrollos constituyen el objeto de estudio de este trabajo. Antonio Beltrán Marí enseña Historia de la Ciencia en la Universidad de Barcelona. Se ha ocupado de problemas de filosofía de la ciencia, publicando artículos sobre Popper y Kuhn especialmente. Pero su trabajo se centra sobre todo en la historia de la ciencia y en especial en la Revolución Científica del siglo XVII. Es autor del libro Galileo.

This book presents a critical analysis of the semantic incommensurability thesis of Thomas Kuhn and Paul Feyerabend. In putting forward the thesis of incommensurability, Kuhn and Feyerabend drew attention to complex issues concerning the phenomenon of conceptual change in science. They raised serious problems about the semantic and logical relations between the content of theories which deploy unlike systems of concepts. Yet few of the more extreme claims associated with incommensurability stand scrutiny. The argument of this book is as follows. (...) The terms of theories with different concepts diverge semantically and the vocabularies of such theories may not be fully intertranslatable. Given the possibility of referential overlap between the terms of conceptually divergent theories, it does not follow that the content of such theories is incomparable. Nor, given the distinction between understanding a language and translation from one language into another, does it follow that the proponents of mutually untranslatable theories are unable to communicate. Neither is it the case that the shift between conceptually divergent theories involves a discontinuous transition between theories which have no common reference or that refer to distinct worlds of their own making. The semantic differences resulting from conceptual variance may be embraced within a thoroughly realist framework on which they are construed as diverse linguistic relations to a fixed and independent reality. -/- The book, which was originally published in 1994, has now been re-issued in the Routledge Revivals series. -/- .

How does science work? Does it tell us what the world is "really" like? What makes it different from other ways of understanding the universe? In Theory and Reality , Peter Godfrey-Smith addresses these questions by taking the reader on a grand tour of one hundred years of debate about science. The result is a completely accessible introduction to the main themes of the philosophy of science. Intended for undergraduates and general readers with no prior background in philosophy, Theory and (...) Reality covers logical positivism the problems of induction and confirmation Karl Popper's theory of science Thomas Kuhn and "scientific revolutions" the views of Imre Lakatos, Larry Laudan, and Paul Feyerabend and challenges to the field from sociology of science, feminism, and science studies. The book then looks in more detail at some specific problems and theories, including scientific realism, the theory-ladeness of observation, scientific explanation, and Bayesianism. Finally, Godfrey-Smith defends a form of philosophical naturalism as the best way to solve the main problems in the field. Throughout the text he points out connections between philosophical debates and wider discussions about science in recent decades, such as the infamous "science wars." Examples and asides engage the beginning student a glossary of terms explains key concepts and suggestions for further reading are included at the end of each chapter. However, this is a textbook that doesn't feel like a textbook because it captures the historical drama of changes in how science has been conceived over the last one hundred years. Like no other text in this field, Theory and Reality combines a survey of recent history of the philosophy of science with current key debates in language that any beginning scholar or critical reader can follow.
