A volume of studies of utilitarianism considered both as a theory of personal morality and a theory of public choice. All but two of the papers have been commissioned especially for the volume, and between them they represent not only a wide range of arguments for and against utilitarianism but also a first-class selection of the most interesting and influential work in this very active area. There is also a substantial introduction by the two editors. The volume will constitute an important stimulus and point of reference for a wide range of philosophers, economists and social theorists.
