Kant's Copernican analogy: beyond the non-specific reading

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. My contention is that something much more specific, systematic is at issue, which contrary to received understanding makes Kant's analogy in fact particularly apt.
