Now happiness above all else appears to be absolutely final in this sense, since we always choose it for its own sake and never as a means to something else; whereas honor, pleasure, intelligence, and excellence in its various forms, we choose indeed for their own sakes (since we should be glad to have each of them although no extraneous advantage resulted from it), but we also choose them for the sake of happiness, in the belief that they will be a means to our securing it. But no one chooses happiness for the sake of honor, pleasure, etc., nor as a means to anything whatever other than itself.

The same conclusion also appears to follow from a consideration of the self-sufficiency of happiness—for it is felt that the final good must be a thing sufficient in itself. The term self-sufficient, however, we employ with reference not to oneself alone, living a life of isolation, but also to one’s parents and children and wife, and one’s friends and fellow citizens in general, since man is by nature a social being.Lit. a political thing. Aristot. Pol. 1253a 2 adds ζῷον, a political animal.
