Utilitarianism and Cooperation

Donald Regan's book is a study of forms of utilitarian theory and of properties to which these forms may aspire. He deals exclusively with “fully objective” theories that seek to systematize and set conditions for obligations that an agent is supposed to lie under as a consequence of features of situations in which he finds himself, with no dependence on his possibly defective beliefs, attitudes, and values (except as features of his situations). Metaethical questions concerning the nature of these obligations are not raised. And practical problems that could be encountered in attempts to apply these theories receive very little attention. They are said to lie outside the main project of the book which is to explain and then to circumvent a certain apparent logical impasse that utilitarianisms ca. 1980 are supposed to confront. The book consists for the most part of abstract, often very long and difficult, arguments, and detailed elaborations of a small number of minimally specified, highly artificial cases of the sort now common in semi-formal utilitarian theory. In the present note, while leaving unquestioned and unstated the presuppositions of Regan's book, I first outline its central two-stage “argument”. Next I explain several distinctions important to issues it addresses and relate these distinctions to several of Regan's theses. I then discuss prima facie cases against his main claim, according to which the apparent impasse that utilitarianisms confront is circumvented by a new utilitarian theory designed for the task.
