We need to hear the voice of history. In "Sex and Culture" (1934) the anthropologist J.D. Unwin found a universal correlation between monogamy and a civilization's "expansive energy." He wrote:
"These [sexually progressive] societies lived in different geographical environments; they belonged to different racial stocks; but the history of their marriage customs is the same. In the beginning each society had the same ideas in regard to sexual regulations. Then the same struggles took place; the same sentiments were expressed; the same changes were made; the same results ensued. Each society reduced its sexual opportunity to a minimum and displaying great social energy, flourished greatly. Then it extended its sexual opportunity; its energy decreased, and faded away. The one outstanding feature of the whole story is its unrelieved monotony."
Why isn’t there any present discussion of these possible costs? An adolescent society wants its desires filled immediately and has no ear for any consideration of the costs. It is willfully blind and condemns others who try to open its eyes.
