Sex and Culture

In 'Sex and Culture', J.D.

Unwin examines the relationship between a civilization’s success and the sexuality of its people.

He studied 80 primitive tribes and 6 known civilizations over 5,000 years of history and found a positive correlation between cultural achievement and the amount of sexual restraint observed.

Unwin argues that societies which impose strict prenuptial and postnuptial sexual restraints tend to achieve higher levels of cultural development, while those that become more sexually liberal experience a decline in their cultural energy and eventual downfall.

He categorizes societies into four cultural conditions: zoistic, manistic, deistic, and rationalistic, based on their spiritual and social practices.

Unwin also emphasizes the importance of legal equality between men and women and the need for absolute monogamy to maintain a high level of cultural achievement.
