 A misunderstanding of eudaimonia as an unmoralized concept leads some critics to suppose that the neo-Aristotelians are attempting to ground their claims in a scientific account of human nature and what counts, for a human being, as flourishing. Others assume that, if this is not what they are doing, they cannot be validating their claims that, for example, justice, charity, courage, and generosity are virtues. Either they are illegitimately helping themselves to Aristotle’s discredited natural teleology (Williams 1985) or producing mere rationalizations of their own personal or culturally inculcated values. But McDowell, Foot, MacIntyre and Hursthouse have all outlined versions of a third way between these two extremes. Eudaimonia in virtue ethics, is indeed a moralized concept, but it is not only that. Claims about what constitutes flourishing for human beings no more float free of scientific facts about what human beings are like than ethological claims about what constitutes flourishing for elephants. In both cases, the truth of the claims depends in part on what kind of animal they are and what capacities, desires and interests the humans or elephants have.
