For more than three decades, the women's movement and its scholars have exhaustively studied women's complex history, roles, and struggles. In Manhood in America: A Cultural History, Fourth Edition, author Michael Kimmel argues that it is time for men to rediscover their own evolution. Drawing on a myriad of sources, he demonstrates that American men have been eternally frustrated by their efforts to keep up with constantly changing standards. Kimmel contends that men must follow the lead of the women's movement; it is only by mining their past for its best qualities and worst excesses that men will free themselves from the constraints of the masculine ideal.
