82:2.1

The story of the evolution of marriage is simply the history of sex control through the pressure of social, religious, and civil restrictions. Nature hardly recognizes individuals; it takes no cognizance of so-called morals; it is only and exclusively interested in the reproduction of the species. Nature compellingly insists on reproduction but indifferently leaves the consequential problems to be solved by society, thus creating an ever-present and major problem for evolutionary mankind. This social conflict consists in the unending war between basic instincts and evolving ethics.
