Abstract

In Moral Failure, Lisa Tessman argues against two principles of moral theory, that ought implies can and that normative theory must be action-guiding. Although Tessman provides a trenchant account of how we are thrust into the misfortune of moral failure, often by our very efforts to act morally, and although she shows, through a discussion well-informed by the latest theorizing in ethics, neuroethics, and psychology, how much more moral theory can do than provide action-guiding principles, I argue that the two theses of moral theory that she disputes remain indispensable for ethical theory.
