Abstract
This article takes up the challenge that the motto “Do What is Right Though the World Should Perish” invites for an answer to Kant's arguments in defense of the motto. His argumentation is discussed, as well as the underlying assumptions concerning the role of Providence, the rejection of moral conflict, and the prudential risks associated with abandoning moral absolutism. The first two are rejected, the third seen as only partially tenable. Finally, the question is taken up what to do about moral prohibitions in a world in which they can quite literally prevent or bring about universal perishing
