Nobody who's stood between a toddler and the last cookie should still harbor a belief in the inherent virtue of mankind. An afternoon at the playground is apt to make one toss out the idealist Rousseau ("man is a compassionate and sensible being") in favor of the more realistic Hobbes ("all mankind [is in] a perpetual and restless desire for power"). As a father of four sons, I've signed on to Mr. Sowell's summation of a parent's duty: "Each new generation born is in effect an invasion of civilization by little barbarians, who must be civilized before it is too late."
