Eudaimonia

Eudaimonia is constituted, according to Aristotle, not by honor, or wealth, or power, but by rational activity in accordance with excellence. Such activity manifests the virtues of character, including courage, honesty, pride, friendliness, and wittiness; the intellectual virtues, such as rationality in judgment; and it also includes non-sacrificial (i.e., mutually beneficial) friendships and scientific knowledge (knowledge of things that are fundamental and/or unchanging is the best).
