Book excerpt: Supererogation is the category of moral actions which go beyond the call of duty. This collection of articles is the first of its kind to cover the broad spectrum of issues related to supererogation. It provides an up-to-date status of the discussion on the main issues, alternative analyses, and controversies regarding central cases of supererogation. The work explores a broad range of philosophical problems and challenges our presuppositions about the basis of ethical theories. Beyond the challenges of supererogation to deontological and utilitarian views, this book presents the latest developments in the way virtue ethics approaches supererogation. It also discusses the issue of whether there is a negative analogue to the supererogatory: the suberogatory. The Handbook consists also of the first systematic discussion of supererogation from the point of view of five religions as well as a feminist analysis of the concept. The book is an essential read for philosophy scholars interested in moral philosophy.
