How St. Augustine Invented Sex

One day in 370 C.E., a sixteen-year-old boy and his father went to the public baths together in the provincial city of Thagaste, in what is now Algeria. At some point during their visit, the father may have glimpsed that the boy had an involuntary erection, or simply remarked on his recently sprouted pubic hair. Hardly a world-historical event, but the boy was named Augustine, and he went on to shape Christian theology for both Roman Catholics and Protestants, to explore the hidden recesses of the inner life, and to bequeath to all of us the conviction that there is something fundamentally damaged about the entire human species. There has probably been no more important Western thinker in the past fifteen hundred years.
