 Despite these challenges, philosophers are still searching for links between duties to self and supererogation. Muñoz (2021), for example, tries to revive Kagan’s argument, arguing that a waivable duty to oneself is a prerogative: it can be cited in defense of one’s actions, but since it can be waived at will, it isn’t a “binding” reason to comply. On this view, duties to self help to unify the two main concepts in deontological ethics: restrictions, which make it wrong to harm non-consenting others even for the greater good, and prerogatives, which permit us not to self-harm. Restrictions come from what we owe to others, and prerogatives come from what we owe to ourselves.
