"I have gradually come to realize that almost all of social science proceeds as if 1859, the year of the publication of the Origin of Species, had never happened; it does so quite deliberately, for it insists that human culture is a product of our own free will and invention. Society is not the product of human psychology, it asserts, but vice versa. That sounds reasonable enough, and it would be splendid for those who believe in social engineering if it were true, but is is simply not true."
