I argue that recent virtue theories (including those of Hursthouse, Slote, and Swanton) face important initial difficulties in accommodating the supererogatory. In particular, I consider several potential characterizations of the supererogatory modeled upon these familiar virtue theories (and their accounts of rightness) and argue that they fail to provide an adequate account of supererogation. In the second half of the paper I sketch an alternative virtue-based characterization of supererogation, one that is grounded in the attitudes of virtuous ideal observers, and that avoids the concerns raised in the first part of the paper.Discussion of the supererogatory in the last half-century has been sparked in large part by J. O. Urmson's 1958 article, ''Saints and Heroes''. 1 Urmson argues that there is a class of actions-the supererogatory-that cannot be adequately accounted for by traditional divisions of actions into the obligatory, the forbidden, and the permissible. He has us consider the actions of a doctor who chooses to travel to a plague-ridden city in order to help combat the crisis, and ease the suffering of those trapped there. It seems too much to demand that all people (or even all doctors) perform such actions-we would not blame other doctors who do not make such extreme sacrifices, and do not take such extreme risks to their own well-being.
