As Socrates famously noted, there is no more important question than how we ought to live. The answer to this question depends on how the reasons that we have for living in various different ways combine and compete. To illustrate, suppose that I've just received a substantial raise. What should I do with the extra money? I have most moral reason to donate it to effective charities but most self-interested reason to spend it on luxuries for myself. So, whether I (...) should live my life as I have most moral reason to live it or as I have most self-interested reason to live it depends on how these and other sorts of reasons combine and compete to determine what I have most reason to do, all things considered. This Element seeks to figure out how different sorts of reasons combine and compete to determine how we ought to live. (shrink)

The problem of supererogation has attracted significant attention from contemporary moral philosophers. In this paper, we show that this problem was outlined in different terms in the work of the 11th century Persian philosopher Abū Alī Miskawayh. As well as identifying this problem, Miskawayh also developed a unique solution cashed out in terms of virtue ethics that has not yet been considered in the contemporary literature. We will argue that this solution, which is in its general form independent of virtue (...) ethics, provides a plausible explanation of what makes some acts supererogatory and faces two important advantages over the most popular response to the problem of supererogation, The Sacrifice View. Unlike The Sacrifice View, The Cautionary Account can class acts of benevolence that advance the agent's own interests as supererogatory and easily explain why certain acts of sacrifice are neither permissible nor praiseworthy.
