 Theories of well-being—and hence of “happiness” in the well-being sense—come in three basic flavors, according to the best-known taxonomy (Parfit 1984): hedonism, desire theories, and objective list theories. Whereas hedonists identify well-being roughly with experiences of pleasure, desire theorists equate it with the satisfaction of one’s desires—actually getting what you want, versus merely having certain experiences. Both hedonism and desire theories are in some sense subjectivist, since they ground well-being in the individual’s subjective states. Objective list theorists, by contrast, think some things benefit us independently of our attitudes or feelings: there are objective prudential goods. Aristotelians are the best-known example: they take well-being (eudaimonia) to consist in a life of virtuous activity—or more broadly, the fulfillment of our human capacities. A passive but contented couch potato may be getting what he wants, and he may enjoy it. But he would not, on Aristotelian and other objective list theories, count as doing well, or leading a happy life.
