 Only a brief discussion of these points of coincidence is possible here. Consider, first, sections 72–75 of A Theory of Justice, where Rawls outlines what he calls the three stages of moral development, governed by three psychological laws. These laws explain how individuals come to have new, non-derivative, final ends as they acquire ties of love, friendship, affection, and trust. As Aristotle recognized, these ties are caused to occur in individuals as they come to recognize others’ evident intention to act for their good, and to enjoy what they and others can do.
