Last time I introduced the idea of supererogatory acts, those that are good beyond what duty and obligation require. The nature of supererogatory acts is sometimes referred to with the noun form supererogation. David Heyd’s Stanford Encyclopedia article makes a good introduction to the idea of supererogation. It also, I think, tells us what analytical moral philosophy gets wrong about the idea – specifically, when it claims that “the class of actions beyond duty is relatively small…”

Says who? Say contemporary ethicists, according to Heyd. But to my mind this does a lot to illustrate what is wrong with their way of thinking. The claim that relatively few actions go beyond the requirements of duty would certainly be true for Peter Singer and most utilitarians and consequentialists, who subject us to an effectively never-ending stream of demands in which little could be supererogatory short of altruistic suicide. Likewise, while I think it would not be hard to allow great room for supererogatory acts in a neo-Kantian position, as Heyd notes this was not Kant’s own view: there were perfect and imperfect duties, but the latter were duties all the same.

But this, I would argue, is one of the many things both utilitarians and Kantians get wrong – and therefore the majority of analytical ethicists, since most major analytical ethics descends from one or both of these sources. Continue reading →
