This short book of essays by Edward Carpenter is a look at gender roles at the start of the 20th century, and his prescient vision of how those roles might evolve. In the past century many of his then-utopian predictions have come to pass, such as rational sexual education, greater equality for women, recognition of a spectrum of sexual identities, widespread acceptance of trial and open relationships, and the amelioration of the stifling nature of traditional marriage. He occasionally draws on some dubious science, tainted by 19th century prudery and attitudes about women. However, for the most part, he scores some very good points which are still relevant.
