In Nicomachean Ethics X.7–8, Aristotle defends a striking view about the good for human beings. According to Aristotle, the single happiest way of life is organized around philosophical contemplation. According to the narrowness worry, however, Aristotle's contemplative ideal is unduly Procrustean, restrictive, inflexible, and oblivious of human diversity. In this paper, I argue that Aristotle has resources for responding to the narrowness worry, and that his contemplative ideal can take due account of human diversity.

It has been many years since the Classical notion of an objective, determinate account of the human good, applicable to all people, has played the central role in most moral theories. One contribution to this decline has been the Kantian belief that one cannot say what happiness is. Kant thinks that happiness is a purely empirical concept and is therefore dependent on contingent, unpredictable objects and states of affairs.

There is a certain conventional interpretation of Aristotle's argument, in Metaphysics Λ.7, for the identification of the first unmoved mover as God, according to which that argument has the following outline.

In I 7 Aristotle lays down criteria for what is to count as human happiness. Happiness for man is self-sufficient , complete without qualification , peculiar to humans , excellent , and best and most complete . Many interpreters agree that in X 6–8 Aristotle uses these along with other criteria to disqualify the life of amusement and rank one happy life above another.
