Abstract

: The paper discusses the concepts of obligation and moral evidence in Mendelssohn’s and Kant’s prize essays. I argue that Mendelssohn departs in significant ways from Christian Wolff’s position, and that Kant intends to overcome Wolffian philosophy with Newtonian methodology while still owing a lot to Wolff and to the project of an ethics within the limits of metaphysics. Although quite akin to Francis Hutcheson’s philosophy, it becomes clear that Kant intended to lay the foundation of an innovative concept of obligation, which shares some similarities with Christian August Crusius’s interpretation of it.
