The starting point is the extensive research of J.D. Unwin, who, in an attempt to verify the Freudian claim that civilization is a byproduct of repressed sexuality, studied 80 different societies. His findings surprised many scholars - primarily himself - because all 80 showed a direct link between monogamy and the "expansion energy" of civilization. To put it another way: the greater a society's sexual abstinence was, the more it expanded and its standard of living improved. However, when social sexual deviancy and attacks on single-partner lifestyles began to occur, societies collapsed. In the 80 cases studied, this pattern was confirmed 80 times. Joseph Unwin (1895-1936), an anthropologist and one of Britain's most prominent scholars in the pre-World War II period, was a professor at Oxford and Cambridge Universities, and in 1934, two years before his death, published his magnum opus, which delights in its depth and, above all, amazes because of the many facts predicted by the author that plague Western societies today. This is an interesting study of the culture of exposure, expressed in the clearly visible sexualization of modern life, especially in its public and media manifestations. The author places the subject of sex and gender against the broad background of the social changes that have taken place and are still taking place in the societies of developed capitalist countries.
