This title presents the evolving differences between women and men. In a sweeping synthesis of American history, Mary Ryan demonstrates how the meaning of male and female has evolved, changed, and varied over a span of 500 years and across major social and ethnic boundaries. She traces how, at select moments of history, perceptions of sex difference were translated into complex and mutable patterns for differentiating women and men. How those distinctions were drawn and redrawn, Ryan shows, affected the course of American history more generally. Ryan's bold analysis raises the possibility that perhaps, if understood in their variety and mutability, the differences of sex might lose the sting of inequality.
