Abstract

Relying on a sexual encounter that he had once while in graduate school, Soble explores in this essay two important and under-explored ideas in sexual ethics. The first is whether there are sexual duties to others (including, even especially, to strangers), and what the source of such duties might be. He provides good reasons, rooted in both religious and secular thought, for believing that such duties exist. The second is whether there are supererogatory sexual actions—sexual actions that go beyond the demands of duty—and what conditions an act needs to satisfy in order to be supererogatory. Soble uses the sexual encounter that opens the essay to test our intuitions about these two ideas and his own arguments, and to underscore the complications involved in attempting to find secure answers as to whether some sexual acts are dutiful, done from duty, or supererogatory. (This is a revised version of the essay in the 7th edition of The Philosophy of Sex.)
