"With his attractive picture of human flourishing, Aristotle offers lasting refuge against the seas of moral relativism. Taking us on a tour of the museum of the virtues — from courage and moderation, through liberality, magnificence, greatness of soul, ambition, and gentleness, to the social virtues of friendliness, truthfulness, and wit — and displaying each of their portraits as a mean between two corresponding vices, ­Aristotle gives us direct and immediate experience in seeing the humanly beautiful. Anyone who cannot see that courage is more beautiful than cowardice or rashness, or that liberality is more beautiful than miserliness or prodigality, suffers, one might say, from the moral equivalent of color-blindness."
