Abstract

The phenomenon of moral supererogation—action that goes beyond what moral duty requires—is familiar. In this paper, I argue that the concept of supererogation is applicable beyond the moral domain. After an introductory section 1, I outline in section 2 what I take to be the structure of moral supererogation, explaining how it comes to be an authentic normative category. In section 3, I show that there are structurally similar phenomena in other normative domains—those of prudence, etiquette, and the epistemic—and give examples of acts of supererogation of each of these types.
