 In part III, Rawls turns to the question of how individuals acquire a desire to act justly, and to do so for the right reasons, when they have lived under and benefited from just institutions (1999a, 399). Rawls’s account is indebted to Aristotle’s views in several ways. First, Rawls holds, as Aristotle did, that if proper institutions are in place, then the attitudes and behaviors associated with the desire to act justly will emerge naturally, as a result of psychological tendencies persons experience in ordinary life. For, other things being equal, it is part of human psychology to enjoy most the exercise of one’s realized powers (see Rawls’s discussion of what he calls the Aristotelian Principle), to enjoy the realization of others’ powers (see his discussion of the “companion effect” to the Aristotelian principle), and to form ties of attachment and friendship to persons and institutions who promote one’s good. Second, and again like Aristotle, Rawls argues that if citizens are fortunate to live in a community that provides the basic goods they need for realizing their powers and that offers them opportunities to develop and use their abilities in shared activities with others, then they will develop a stable sense of their own value that is based on their own accomplishments and their status as equal citizens, rather than on a position more advantaged relative to others. With a stable sense of their own value and a reasonable hope of achieving their aims, citizens will want to act justly for the right reasons. They will not be prone to rancor, jealousy, and hostile envy, “one of the vices of hating mankind” (1999a, 466).
