 What should go on the list (Moore 2000)? It is important that every good should be included. As Aristotle put it: ‘We take what is self-sufficient to be that which on its own makes life worthy of choice and lacking in nothing. We think happiness to be such, and indeed the thing most of all worth choosing, not counted as just one thing among others’ (Nicomachean Ethics, 1097b, tr. Crisp). In other words, if you claim that well-being consists only in friendship and pleasure, I can show your list to be unsatisfactory if I can demonstrate that knowledge is also something that makes people better off.
