Abstract

Does it ever happen that there are things we shouldn’t do and the reasons we shouldn’t do them are moral reasons, yet doing them is not morally wrong? Surprisingly, yes. I argue for a category that has not been recognized by moral theorists: morally permissible moral mistakes. Sometimes a supererogatory action is the thing a person should do; in failing to act, one makes a morally permissible moral mistake. Recognizing the category of morally permissible moral mistakes solves a puzzle about supererogation, expands the universe of possible moral views, and shows some apparently inconsistent moral views to be consistent
