Can a boy be “trapped” in a girl’s body? Can modern medicine “reassign” sex? Is our sex “assigned” to us in the first place? What is the most loving response to a person experiencing a conflicted sense of gender? What should our law say on matters of “gender identity”?

When Harry Became Sally provides thoughtful answers to questions arising from our transgender moment. Drawing on the best insights from biology, psychology, and philosophy, Ryan Anderson offers a nuanced view of human embodiment, a balanced approach to public policy on gender identity, and a sober assessment of the human costs of getting human nature wrong.
