This article criticizes the attempts by Bas van Fraassen and Michael Friedman to address the challenge to rationality posed by the Kuhnian analysis of scientific revolutions. In the paper, I argue that van Fraassen's solution, which invokes a Sartrean theory of emotions to account for radical change, does not amount to justifying rationally the advancement of science but, rather, despite his protestations to the contrary, is an explanation of how change is effected. Friedman's approach, which appeals to philosophical developments at (...) a meta-theoretical level, does not really address the problem of rationality as posed by Kuhn's work. Instead of showing how, despite revolutions, scientific development is, indeed, rational, he gives a transcendental account of rational scientific progress. (shrink)

Both Kuhn and Cavell acknowledge their indebtedness to each other in their respective books of the 60s. Cavell in (Must We Mean What We Say (1969)) and Kuhn in (The Structure of Scientific Revolutions 1962). They were together at Berkeley where they had both moved in 1956 as assistant professors after their first encounter at the Society of Fellows at Harvard (Kuhn 2000d, p. 197). In Berkeley, Cavell and Kuhn discovered a mutual understanding and an intellectual affinity. They had regular (...) conversations which Cavell describes as "extremely important" (Conant 1989, p. 40; cf. Cavell 1979, p. xix). Cavell says that he felt he wanted to assure Kuhn that "philosophy did not have standing answers to the questions [Kuhn] .. (shrink)

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)

This paper discusses conceptual relativism. The main focus is on the contrasting ideas of Wittgenstein and Davidson, with Quine, Kuhn, Feyerabend and Hacker in supporting roles. I distinguish conceptual from alethic and ontological relativism, defend a distinction between conceptual scheme and empirical content, and reject the Davidsonian argument against the possibility of alternative conceptual schemes: there can be conceptual diversity without failure of translation, and failure of translation is not necessarily incompatible with recognizing a practice as linguistic. Conceptual relativism may (...) be untenable, but not for the hermeneutic reasons espoused by Davidson. (shrink)
