Aristotle's Virtue

 In the Nicomachean Ethics, Aristotle defined a virtue as a balance point between a deficiency and an excess of a trait.[The point of greatest virtue lies not in the exact middle, but at a golden mean sometimes closer to one extreme than the other. For example, courage is the mean between cowardice and foolhardiness, confidence the mean between self-deprecation and vanity, and generosity the mean between miserliness and extravagance. To find the golden mean requires common-sense smarts, not necessarily high intelligence. In Aristotle's sense, virtue is excellence at being human, a skill that helps a person survive, thrive, form meaningful relationships, and find happiness. Learning virtue is usually difficult at first, but becomes easier with practice over time until it becomes a habit.
