Abstract

Immanuel Kant’s major book on his legal and political philosophy, the Doctrine of Right, appears in 1797. Therefore, many scholars have argued that Kant’s entire legal philosophy has only been developed in the late 1790s and that it is for the most part independent from his critical writings on moral philosophy dating in the 1780s. This article, however, tries to proof the contrary by analyzing the1784 lecture notes Moral-Mrongovius II given by Christoph Coelestin Mrongovius, who attended Kant’s lecture on moral philosophy at that time. Those lecture notes not only proof that Kant’s concept of right has already been worked out in 1784. Even more: Moral-Mrongovius II indicates that Kant considered his legal philosophy as an integral part of his overall critical moral philosophy.
