Mankind’s moral sense is not a strong beacon light, radiating outward to illuminate in sharp outline all that it touches. It is, rather, a small candle flame, casting vague and multiple shadows, flickering and sputtering in the strong winds of power and passion, greed and ideology. But brought close to the heart and cupped in one’s hands, it dispels the darkness and warms the soul.
--James Q. Wilson, The Moral Sense
