 Aristotle’s conclusion about the nature of happiness is in a sense uniquely his own. No other writer or thinker had said precisely what he says about what it is to live well. But at the same time his view is not too distant from a common idea. As he himself points out, one traditional conception of happiness identifies it with virtue (1098b30–1). Aristotle’s theory should be construed as a refinement of this position. He says, not that happiness is virtue, but that it is virtuous activity. Living well consists in doing something, not just being in a certain state or condition. It consists in those lifelong activities that actualize the virtues of the rational part of the soul.
