Abstract

Supererogatory actions must go beyond duty not only by being optional, but also by being good to do. Understanding the evaluative condition that supererogatory actions must meet is vital in order to understand the very concept of supererogation. I argue for two key features of the goodness of supererogatory actions: firstly, that they are comparative, and secondly, that they are relative. Specifically, I argue that an action meets the evaluative condition of supererogation if and only if it is (i) better than some permissible alternative and (ii) better than (or at least as good as) all permissible alternatives that are (a) as costly or (b) less costly; where the sense in which it is better is relative to a particular beneficiary. Seeing why this is so reveals the complexity of our notion of the supererogatory and captures our intuitions on core and complex cases. Furthermore, it makes room for supererogation’s mirror: the suberogatory.
