Against those commentators who consider Kant’s explicit reference to Copernicus’s heliocentric reversal either grossly misleading or simply irrelevant to the revolution in philosophy carried out in the Critique of Pure Reason, it is argued in this paper that Kant’s transcendental idealist inversion of the familiar standpoint of realism and sound common sense fully justifies the talk of a ‘Copernican revolution,’ even if Kant himself never used the expression. It is not just the dominant ‘moving spectator’ motif (or transcendental turn) of the Preface that has to do with Copernicus; both the immediately following ‘crucial experiment’ motif (on the distinction between appearances and things in themselves) and the ‘critical’ motif (regarding self-knowledge and the possibility of synthetic a priori judgments) confirm the aptness of the Copernican analogy. Still, some commentators have stretched the analogy too far; the final section of the paper attempts to determine just how far it may reasonably be said to go.
