In his recent book,The Evolution of Modern Metaphysics, Adrian W. Moore takes Kant to play a crucial role in the evolution of modern philosophy; yet, for him, Kant’s metaphysics is ultimately and profoundly unsatisfactory. In this article, I examine several of Moore’s objections and provide replies. My claim is that Moore’s reading points to fundamental issues, yet these are not issues of Kant’s transcendental idealism, but of the traditional idealism his view has often been taken to represent.
