Often translated as "happiness" or "flourishing," eudaimonia refers not to a feeling but to a life well-lived, the actualization of human potential through virtuous activity over a complete lifetime.

Aristotle begins with a claim that seems obvious but has profound implications: every action and pursuit aims at some good. We exercise to be healthy, we work to earn money, we earn money to buy things we need. But this immediately raises a question: is there some ultimate good that we pursue for its own sake, not as a means to something else? If not, then our desires form an infinite regress: we always want something for the sake of something else, and nothing is ultimately worth pursuing. This would make practical deliberation impossible.
Aristotle argues there must be such an ultimate end, and everyone agrees on what to call it: _eudaimonia_. This Greek term is notoriously difficult to translate. "Happiness" is the most common rendering, but it can be misleading. Modern English speakers tend to think of happiness as a subjective feeling, a pleasant emotional state. You can be happy watching television or eating ice cream. Aristotle's _eudaimonia_ is something different: objective and comprehensive, the condition of living well and doing well. It is the kind of flourishing that comes from actualizing your potential as a human being over a complete lifetime.
To see the difference, imagine someone who feels cheerful and satisfied but lives a life of shallow pleasures and wasted potential. In modern terms, we might say they're happy. Aristotle would say they lack _eudaimonia_. Conversely, consider someone facing great difficulties with courage and integrity, pursuing worthy goals, and maintaining meaningful relationships. Even if they experience less moment-to-moment pleasure, Aristotle would recognize them as flourishing in the deepest sense.
The crucial question, then, is what _eudaimonia_ actually consists in. Here Aristotle makes his most distinctive move.
