For Aristotle, human beings are end-setting creatures. We seek things for ourselves that we believe are good, and some of these things we pursue for their own sake, while others we pursue for the sake of other things. He appeals to this distinction in the quote above, and it’s the same distinction we’ve seen Plato draw earlier in this course between ends and means.
Philosophers often refer to goods that we regard as ends as “intrinsically valuable” and goods that we regard as means as “instrumentally valuable.” Aristotle recognizes also that the goods in our lives that we regard as ends are tied to certain roles that we identify with or pursuits that we characteristically engage in. As he notes at the very beginning of the Nicomachean Ethics, the health of one’s patient is the end of the doctor, a ship is the end of the shipbuilder, victory is the end of the general, and wealth is the end of household management. What any given human being regards as intrinsically valuable will therefore depend on these roles we occupy.
No matter what roles we occupy, however, there is one end that every human being considers of ultimate intrinsic value according to Aristotle—what he calls our “final end” and “unconditionally complete” (NE I.7, 1097b)—and this is one’s own happiness. By “happiness,” Aristotle is not referring to a life filled with short-term pleasures, but a life of long-term fulfillment: a meaningful life. This is what the Greeks termed eudaimonia, a state of flourishing and being happy rather than merely feeling happy.
