Abstract
Philosophical and popular ethics tend to focus on the question "What ought I to do?" Is there, in addition to the ethics of action, an ethics of fantasy? Are there fantasies one ought not to have? Of course there are fantasies with horrific content. Does it follow that there is something wrong with a person who has such fantasies or that they ought to make efforts to suppress them or to otherwise change themselves? Do the problems such fantasies raise depend on their links to desire and action? Masturbation fantasies are considered as well as fantasies that may emerge during sex with others, fantasies that include actual others, and fantasies that get embodied in pornography. Psychoanalytic and legal aspects of the issues are emphasized. 2012 APA, all rights reserved)
