Homosexuality: A Philosophical Inquiry is a 1988 book by the philosopher Michael Ruse, in which the author discusses different theories of homosexuality, evaluates the moral status of homosexual behavior, and argues in favor of gay rights. The book received both positive and negative reviews. Some reviewers praised it for Ruse's comprehensive treatment of his subject, careful discussion of theories about homosexuality, and use of philosophy to support gay rights. However, Ruse's treatment of psychoanalysis, sociobiology, and social constructionism, and his use of historical evidence to discuss homosexuality in past societies, were criticized. Commentators noted that some of Ruse's comments about homosexuality could be considered insensitive, and also suggested that Ruse's arguments and conclusions about the subject were influenced by his personal reaction to the AIDS epidemic.
