For three decades, Alan Soble has supplied the authoritative roadmap for students and faculty who study the subject of sex. In this new fifth edition of The Philosophy of Sex, Soble and co-editor Nicholas Power have collected thirty contemporary essays that explore philosophically, conceptually, and theologically the nature, social meanings, and morality of contemporary sexual phenomena. Contributors address myriad topics, including cybersex and the Internet, masturbation, contraception, sexual perversion, gay and lesbian sexuality, same-sex marriage, casual sex and promiscuity, pedophilia, rape and date rape, sexual use and objectification, sexual relationships between teachers and students, pornography, and prostitution. NEW to this edition: Each of the thirty essays is preceded by an informative introduction written by the two editors and each essay is followed by a set of provocative study questions developed by the editors to stimulate critical thinking about sexuality. Contributing authors, some of whom were commissioned for this new edition, include Martha Nussbaum, Thomas Nagel, Alan Goldman, John Finnis, Sallie Tisdale, Jerome Neu, Robin West, Louise Collins, Alan Wertheimer, Greta Christina, John Corvino, Cheshire Calhoun, Raja Halwani, Yolanda Estes, and others. The editors provide a comprehensive bibliography of over 700 philosophical and general readings in sexuality. Intended in part as a textbook for use in university courses in the philosophy of sex, gender, and ethics, the book is also a valuable resource for researchers in sexuality and a reader-friendly introduction to puzzles about sexuality for anyone who enjoys exploring this ubiquitous human experience.
