Summary |
Thomas Samuel Kuhn (1922-1996) was a historian and philosopher of science whose extremely popular book, The Structure of Scientific Revolutions, has had a profound and enduring impact on the philosophy of science. In Structure, Kuhn proposed a model of scientific theory change according to which science advances by revolutionary displacement of the theoretical structures he called "paradigms". Kuhn's account of such scientific revolutions was controversial because it appeared to suggest that such theoretical change cannot be made on a rational basis due to the incommensurability of alternative paradigms. It also contains a challenge to the scientific realist view that scientific progress constitutes a continual progression toward the truth about the world. Kuhn continued to develop his ideas in later publications in a way which led to a moderation of his views about theory choice, though he retained his anti-realist view. He later claimed that science is governed by a set of epistemic values that provide the rationale for theory choice, though these values do not constitute an algorithm for theory choice. He also developed a refined view of the incommensurability thesis, according to which there is a translation failure between a narrow group of interdefined terms within competing theories, but this untranslatability does not prevent mutual understanding between advocates of rival theories. Kuhn is best known for his model of scientific theory change and some of the controversial philosophical ideas associated with this model. But he was also the author of several major works in the history of physics. |
