-Aristotle maintained that every human action is based on achieving a good as an end. There are different "levels" or "tiers" or good, and the ultimate highest good is happiness.
-Asking why we do the things we do helps us determine our final end (overall good).
-To be an ultimate end, an act must be self-sufficient and final, “that which is always desirable in itself and never for the sake of something else” (Nicomachean Ethics, 1097a30-34), and it must be attainable by man.
-Happiness depends on acquiring a moral character, where one displays the virtues of courage, generosity, justice, friendship, and citizenship in one’s life. Virtuous acts must be done genuinely.
