In this article, I examine two aspects of the transition from Kant to Fichte: systematicity and the primacy of practical reason. It is commonly agreed that Kant saw the critical exercise as an occasion to renew, rather than supress, the possibility of a positive metaphysics; however, most scholars now consider the “system” he sketched to be the sole heritage of Schulmetaphysik. However, I take literally Kant’s demand for a system that expects from the “practical” a new and absolute “foundation,” rather than a system that must be completed. Here, Fichte’s perspective gives us the common thread.
