Thomas Kuhn's, book The Copernican Revolution deserves to be regarded as the best of that small group of longue duree histories that mark postwar historiography of science. In many respects, it is probably the single most influential one. Tightly written and brilliantly argued, it is responsible, together with The Structure of Scientific Revolutions, for the continued popularity of the metaphor of revolution in science among scholars and students alike. Yet, surprisingly, while aspects of the story conceived in Kuhn's original account (...) have been debated, researched, and considerably revised, his overall understanding of a scientific revolution initiated by Copernicus has received no detailed scrutiny. The same may be said of the deployment of Copernican episode in Structure. Finally, a critical appreciation is in order not least because Kuhn's story is so compact and his language at times metaphorical. (shrink)

There are two widely held views in the literature as regards Wittgenstein’s philosophy. One says that Wittgenstein in his later work appeals to ordinary language in his effort to show how the philosophical problems can be dissolved, and the other says that his investigation is a grammatical one. This paper undertakes to examine what is meant by a grammatical investigation, especially in view of the fact that this investigation relies on empirical facts that have to do with linguistic usage. The (...) examination is carried out by concentrating on what Wittgenstein has to say on the issue of knowledge – in particular, how the way we use the word contributes to the dismissal of Moore's answer to the challenge of scepticism. The conclusion is that Wittgenstein's resort to ordinary language is not typically empirical. The examples of ordinary usage that he cites may be contingent, but they could not have been different given the language games they are part of. The correct use of words Wittgenstein appeals to is not fixed by some kind of essence, but neither is it decided by a majority rule. It gets entrenched in a complex nexus of practices. Wittgenstein's reference to “use” instead of ‘usage”and to “linguistic facts” instead of “sociological facts” lends support more to a logical than to an empirical investigation. (shrink)

In Chapter 4 of Science and Subjectivity, I offered several arguments critical of Professor Thomas Kuhn's views as expressed in his influential book The Structure of Scientific Revolutions. His recent replies to these criticisms seem to me so inadequate as to suggest that he, and therefore others as well, may have failed to grasp their full import. Accordingly, I shall, in the first part of this paper, briefly recapitulate my earlier arguments and offer a short rejoinder to Professor Kuhn's replies. (...) The second part of the paper will expand upon my earlier discussion to consider the basic metaphors of vision and revolution, offered by Kuhn to replace the traditional notion of deliberation. My argument here will be that these new metaphors are incongruous in critical respects, and my discussion will conclude by considering their relations to the contrast between understanding and accepting a theory.

Black-Body Theory and the Quantum Discontinuity, 1894-1912. Thomas S. Kuhn .

Important to Kuhn's account of scientific change is the observation that when paradigms are in competition with one another, there is a curious breakdown of rational argument and communication between adherents of competing programs. He attributed this to the fact that competing paradigms are incommensurable. The incommensurability thesis centrally involves the claim that there is a deep conceptual gap between competing paradigms in science. In this paper I argue that in one important case of competing paradigms, the Aristotelian explanation of (...) the properties of bodies in terms of matter and form as opposed to the Cartesian mechanist paradigm, where the properties of bodies are explained on the model of machines, there was no such conceptual gap: the notion of a machine was as fully intelligible on the Aristotelian paradigm as it was on the Cartesian. But this does not mean that the debate between the two sides was conducted on purely rational terms. Rational argument breaks down not because of Kuhnian incommensurability, I argue, but because of other cultural factors separating the two camps. (shrink)
