 Most of the Greek moralists think that, if we are rational, we aim at living well (eu zên) or happiness (eudaimonia). Living well or happiness is our ultimate end in that a conception of happiness serves to organize our various subordinate ends, by indicating the relative importance of our ends and by indicating how they should fit together into some rational overall scheme. So the Stoics identify happiness with “living coherently” (homologoumenôs zên), and Aristotle says that happiness is “perfect” or “complete” (teleios) and something distinctively human. When we are living well, our life is worthy of imitation and praise. For, according to the Greek moralists, that we are happy says something about us and about what we have achieved, not simply about the fortunate circumstances in which we find ourselves. So they argue that happiness cannot consist simply in “external goods” or “goods of fortune,” for these goods are external to our own choosing and deciding. Whatever happiness is, it must take account of the fact that a happy life is one lived by rational agents who act and who are not simply victims of their circumstances.
