The article argues that Polanyi was a likely source of influence on the theory of science that Kuhn developed in his The Structure of Scientific Revolutions. The striking similarity between Kuhn’s idea ofincommuensurability and Polanyi’s rendering of scientific controversy in Personal Knowledge is featured here, and is used to expose a tension between Polanyi's notions of scientific controversy and unfolding truth.

Michael Polanyi’s work has often been conflated with that of Thomas Kuhn. This article shows that although Polanyi and Kuhn both conceded the similarities in some aspects of their accounts of science, both were critical of the other’s position. The key to a correct understanding of the tensions between the authors and their views is to recognize the clash of worldviews within which their philosophies of science were constructed.

After the publication of The structure of scientific revolutions, Kuhn attempted to fend off accusations of extremism by explaining that his allegedly “relativist” theory is little more than the mundane analytical apparatus common to most historians. The appearance of radicalism is due to the novelty of applying this machinery to the history of science. This defence fails, but it provides an important clue. The claim of this paper is that Kuhn inadvertently allowed features of his procedure and experience as an (...) historian to pass over into his general account of science. Kuhn’s familiar claims, that science is directed in part by extra-scientific influences; that the history of science is divided by revolutionary breaks into periods that cannot be easily compared; that there is no ahistorical standard of rationality by which past episodes may be judged; and that science cannot be shown to be heading towards the Truth—these now appear as methodological commitments rather than historico–philosophical theses.Author Keywords: Kuhn; Koyré; Butterfield; Historicism; Revolution.

This essay is a study of Polanyi’s career as scientist and philosopher from the point of view of the history of science, starting with the first step in his academic career helped by an intervention of Albert Einstein. Polanyi’s ideas are better understood if placed against the background of then-fashionable philosophical movements, including logical positivism, and his disagreement with Bukharin in 1935. The essay studies the sources and ambitions of Polanyi’s notion of the tacit dimension, his attitude to evolution and (...) “emergence,” and his contribution to the search for the origins of Einstein’s Relativity Theory. His success in the last of these is shown to be an exemplar of Polanyi’s own philosophy. (shrink)
