Louis Pasteur’s defeat of belief in spontaneous generation has been a classical rationalist example of how the experimental approach of modern science can reveal superstition. Farley and Geison told a counter-story of how Pasteur’s success was due to political and ideological support rather than superior experimental science. They claimed that Pasteur violated proper norms of scientific method, and that the French Academy of Science did not see this, or did not want to. Farley and Geison argued that Pouchet’s experiments were (...) as valid as those of Pasteur. In this paper I argue that the core of the scientific debate was not general theories for or against spontaneous generation but the outcome of specific experiments. It was on the conduct of these experiments that the Academy made judgements favorable to Pasteur. Claude Bernard was a colleague of Pasteur, supportive and sometimes critical. I argue that Bernard’s fact-oriented methodology of “experimental medicine” is a better guide to explaining the controversy than the hypothetic-deductive view of scientific method typical of logical empiricism.

This essay examines the relationship between Philipp Frank and James Bryant Conant in light of two issues that engaged leading American intellectuals in the mid-twentieth century: the place of metaphysics in higher education and the responsibilities of intellectuals as educators to defend democracy against the rise of totalitarianism. It suggests that Frank’s relationship to pragmatism was nourished by his professional and intellectual relationships to Conant and that each of their contributions to our understanding of science is inseparable from their efforts (...) to engage their fellow intellectuals as well as the public about these pressing issues of their day.

Thomas Kuhn's philosophy of science, which he developed by focusing on physics, was later applied by other authors to virtually all areas or disciplines of culture. What interests me here, however, is the movement in the opposite direction: the role that one of these disciplines, history of art, played in the conception of Kuhn'stheoryof science.In a 1969 article, his only published text concerning science and art, Kuhn makes a brief and intriguing observation about The Structure of Scientific Revolutions. He says (...) the book was a belated product of his discovery of the parallels between science and art. This is a retrospective assertion about Structure, as well as that of the... (shrink)

Moti Mizrahi has argued that Thomas Kuhn does not have a good argument for the incommensurability of successive scientific paradigms. With Rouse, Andersen, and others, I defend a view on which Kuhn primarily was trying to explain scientific practice in Structure. Kuhn, like Hilary Putnam, incorporated sociological and psychological methods into his history of science. On Kuhn’s account, the education and initiation of scientists into a research tradition is a key element in scientific training and in his explanation of incommensurability (...) between research paradigms. The first part of this paper will explain and defend my reading of Kuhn. The second part will probe the extent to which Kuhn’s account can be supported, and the extent to which it rests on shaky premises. That investigation will center on Moti Mizrahi’s project, which aims to transform the Kuhnian account of science and of its history. While I do defend a modified kind of incommensurability, I agree that the strongest version of Kuhn’s account is steadfastly local and focused on the practice of science. (shrink)
