Comments on Gabriele Gava, Kant’s Critique of Pure Reason and the Method of Metaphysics

Abstract

I raise three objections for Gava’s thesis that the primary task of the Critique of Pure Reason is to develop a doctrine of method for metaphysics, understood as an account of the special kind of unity that a body of cognitions must exhibit to count as a science. First, I argue that this thesis has difficulty accommodating Kant’s concern with explaining the possibility of synthetic a priori judgements. This concern is motivated by a question that is prior to the issue of scientific unity. Second, I argue that the context of the passage in which Kant calls the Critique a treatise on method makes clear that the remark concerns the Copernican Turn. This suggests that the method treated in the book is the procedure required by the Copernican Turn. Third, I dispute Gava’s claim that the idea that confers unity on metaphysics is the cosmopolitan concept of philosophy.
