In Sex and Culture (1934), Unwin studied 80 primitive tribes and 6 known civilizations through 5,000 years of history and claimed there was a positive correlation between the cultural achievement of a people and the sexual restraint they observe.[1] Aldous Huxley described Sex and Culture as "a work of the highest importance".[2]
According to Unwin, after a nation becomes prosperous it becomes increasingly liberal with regard to sexual morality and as a result loses its cohesion, its impetus and its purpose. The effect, says the author, is irrevocable.[3] Unwin also claimed that legal equality between women and men was a necessary prerequisite to absolute monogamy.[4]
