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.

Perhaps the most remarkable feature of Aristotle's teaching concerns the goals of ethical conduct. Unlike the moralists, Aristotle does not say that morality is a thing of absolute worth or that the virtuous person acts in order to adhere to a moral rule or universalizable maxim. And unlike the utilitarians, he does not say morality is good because it contributes to civic peace or to private gain and reputation. Instead, Aristotle says over and over again that the ethically excellent human being acts for the sake of the noble, for the sake of the beautiful. The human being of fine character seeks to display his own fineness in word and in deed, to show the harmony of his soul in action and the rightness of his choice in the doing of graceful and gracious deeds. The beauty of his action has less to do with the cause that his action will serve or the additional benefits that will accrue to himself or another — though there usually will be such benefits. It has, rather, everything to do with showing forth in action the beautiful soul at work, exactly as a fine dancer dances for the sake of dancing finely. As the ballerina both exploits and resists the downward pull of gravity to rise freely and gracefully above it, so the person of ethical virtue exploits and elevates the necessities of our embodied existence to act freely and gracefully above them. Fine conduct is the beautiful and intrinsically fulfilling being-at-work of the harmonious or excellent soul.

Even the modern word "concept" means "a grasping together," implying that the mind itself, in its act of knowing, functions like the intervening hand (in contrast to its ancient counterpart, “idea,” “that which can be beheld,” which implies that the mind functions like the receiving eye). And modern science rejects, as meaningless or useless, questions that cannot be answered by the application of method. Science becomes not the representation and demonstration of truth, but an art: the art of finding the truth—or, rather, that portion of truth that lends itself to be artfully found.
