 At the first stage of moral development, on the assumption that family institutions are just, children come to love their parents as a result of their parents’ demonstrating clearly that their children are enjoyed and valued. At the second stage, on the assumption that cooperative associations are fairly arranged and known to be so, members of reasonably successful cooperative associations (Rawls’s “social unions”) come to enjoy and value their cooperative partners. This happens when members do their parts responsibly, each contributing to a mutually recognized goal, and where all participants display appropriate abilities. Under these conditions, participants come to enjoy their own participation, to enjoy the display of others’ skills and abilities, and to form ties of friendship and trust with their cooperative partners. Because the activities are complementary, individuals can see themselves in what others do. In this way, individuals’ sense of what they are doing is worthwhile. Their self-love, to use Aristotelian language, becomes a group achievement.
