“Knowledge about bodies does not stand passively by, awaiting discovery by an objective and dispassionate Science. Beyond measurable facts, knowledge about bodies is something we create. We go looking for it, and we fashion it in ways that respond to cultural needs and aims. We create the idea of binary genders because it marks something we want to track and control about bodies' appearance and behavior. We create gender identity disorders because we want to control sex [...] We create the knowledge of sexual orientation and study it exhaustively because we want to know and control the individual's capacity to contribute to reproduction. There is no bright-line separation here between knowledge and politics. Knowledge marches to the beat of power. Specific kinds of knowledge about bodies enable us to exercise specific kinds of power over them. Such knowledge is not 'disinterested'.”
