Conspicuously absent from most discussions of the abortion issue are considerations of third-party interests, especially those of the father. A survey of the literature reveals an implicit assumption by most writers that the issue is to be viewed as a two-party conflict-the rights of the fetus versus the rights of the mother-and that an adequate analysis of the balance of these rights is sufficient to determine the conditions under which abortion is morally permissible. I shall argue, however, that in some cases it would be morally impermissible for a woman to have an abortion because it would be a wrongful harm to the father and a violation of his autonomy. Moreover, I shall argue for this on principles that I believe require a strong stand on women's rights.
