Book excerpt: Passion and Power brings together some of the most recent and innovative writings on the history of sexuality and explores the experiences, ideas, and conflicts that have shaped the emergence of modern sexual identities. Arguing that sexuality is not an unchanging biological reality or a universal natural force, the essays in this volume discuss sexuality as an integral part of the history of human experience. Articles on sexual assault, homosexuality, birth control, venereal disease, sexual repression, pornography, and the AIDS epidemic examine the ways that sexuality has become a core element of modern social identity in the nineteenth- and twentieth-century United States.It is only in recent years that historians have begun to examine the social construction of sexuality. This is the first anthology that addresses this issue from a radical historical perspective, examining sexuality as a field of contention in itself and as part of other struggles rooted in divisions of gender, class, and race.
