The purpose of this paper is to make sense of the immediate philosophical aftermath of Kant's Inaugural Dissertation. I will try to show what Kant himself took to be the problems left unsettled in the dissertation, and how he tried to deal with them. At the end of the paper, I will briefly sketch how he may have proceeded after the famous letter to Marcus Herz of 1772, and what path he would have had to take to recognize the need for a transcendental deduction.
