It is sometimes thought that it is part of the notion of morality that moral norms are backed up by sanctions of some special sort. This view is sometimes explicitly argued for, as by T. L. S. Sprigge, and sometimes appears in the background of discussions that are centered around other issues, as in Narveson's The Libertarian Idea. The aim of this paper is to show that difficulties in attempts to analyze the notion of morality by appealing to moral sanctions go much deeper than is usually realized.
