Critics often accuse Kant and Kantians of rigorism: of advocating highly general exceptionless principles of duty that strictly prohibit action kinds like lying or breaking promises. In this article, I draw on arguments from the generalism-particularism debate to show that the way in which Kantians usually understand universality prevents them from solving this problem and leaves them stuck in a trilemma. I then argue that they should abandon this common conception—the “strict conception,” on which universal principles don’t permit any exceptions—in (...) favor of a “relaxed conception,” on which universal principles do permit certain exceptions, namely principled exceptions.
