Disjunctive duties and supererogatory sets of actions

Abstract

James Urmson famously claimed that all ethical theories which only operate with the three deontic categories of the required, the optional, and the forbidden were ‘totally inadequate to the facts of morality’ because they fail to recognise a fourth category of actions, which we can call the supererogatory. Supererogatory actions should be seen as ‘meritorious non-duty’, as something which is good but in no sense required. A number of examples can be provided to make the existence of such a realm outside duty plausible: the soldier throwing herself on a live hand grenade to save her companions, the torture victim who forgives her tormentors even though they do not regret, or the doctor who voluntarily travels to a war zone to treat the wounded.
