"I believe-and human psychologists, particularly psychoanalysts should test this-that present-day civilized man suffers from insufficient discharge of his aggressive drive. It is more than probable that the evil effects of the human aggressive drives, explained by Sigmund Freud as the results of a special death wish, simply derive from the fact that in prehistoric times intra-specific selection bred into man a measure of aggression drive for which in the social order today he finds no adequate outlet."

We normally think of history as one catastrophe after another, war followed by war, outrage by outrage - almost as if history were nothing more than all the narratives of human pain, assembled in sequence. And surely this is, often enough, an adequate description. But history is also the narratives of grace, the recountings of those blessed and inexplicable moments when someone did something for someone else, saved a life, bestowed a gift, gave something beyond what was required by circumstance.
