Thomas Laqueur’s important book, Making Sex: Body and Gender from the Greeks to Freud (1990), is almost twenty-five years old, and his governing narrative, that the late eighteenth century saw a shift from a “one-sex” to a “two-sex” body in Western society, has gained broad acceptance among modern historians and scholars in literary and cultural studies. “Rethinking the ‘One-Sex’ Body” brings together this new research to ask if Laqueur is wrong, and, if so, how he’s wrong and what difference it makes.
