 In the ancient world, courage, moderation, justice and piety were leading instances of moral virtue. A virtue is a settled disposition to act in a certain way; justice, for instance, is the settled disposition to act, let’s say, so that each one receives their due. This settled disposition consists in a practical knowledge about how to bring it about, in each situation, that each receives their due. It also includes a strong positive attitude toward bringing it about that each receives their due. Just people, then, are not ones who occasionally act justly, or even who regularly act justly but do so out of some other motive; rather they are people who reliably act that way because they place a positive, high intrinsic value on rendering to each their due and they are good at it. Courage is a settled disposition that allows one to act reliably to pursue right ends in fearful situations, because one values so acting intrinsically. Moderation is the virtue that deals similarly with one’s appetites and emotions.
