Abstract

Morality is fundamentally impartial. No one can be simply excluded from moral consideration without justification in terms of a morally relevant distinction. I claim that moral impartiality justifies establishing the presumption in favor of duties to oneself. I vindicate this claim against the challenge that there must be a morally relevant self-other distinction which explains the commonsense moral asymmetry. I show that the asymmetry can be explained instead by the presupposition of consent. I end by responding to the objection that the consent-based explanation of the asymmetry condemns potential duties to oneself as practically uninteresting.
