Abstract

References to Kant’s so-called Copernicanism or Copernican turn are often put in very general terms. It is commonly thought that Kant makes the Copernican analogy solely in order to point out the fact as such of a paradigm shift in philosophy. This is too historical an interpretation of the analogy. It leaves unexplained both Kant’s and Copernicus’ reasons for advancing their respective hypotheses, which brought about major changes in the conceptual schemes of philosophy and astronomy. In this article, I consider whether (1) Kant actually speaks of an analogy with Copernicus here and (2) he indeed herewith refers to the Copernican revolution, more in particular the postulation of the heliocentric universe. In this context, I explain that there is a greater systematic relation between Kant and Copernicus than heretofore believed, which contrary to received understanding makes Kant’s analogy in fact particularly apt.
