Abstract

This essay, one of the last that Frankena wrote, provides a scrupulously detailed exploration of the various possible meanings of one of Sidgwick's most famous footnotes in the Methods Long intrigued by what Sidgwick had in mind when he said that he would explain how it came about that for moderns it is not tautologous to claim that one's own good is one's only reasonable ultimate end, Frankena uses this note as a point of departure for a penetrating review of Sidgwick's insights and ambiguities on the differences between ancient and modern ethics.
