Altruism/Rawls: the fully developed (perfect) altruism has a peculiarity: the altruist can only fulfil his desires if someone else has an independent desire. For example, suppose everyone decides to do the same. Then nothing happens. Since a system of justice could never emerge, it is necessary to assume that at least two people have individual interests that can come into conflict. The theory of justice as fairness addresses this by demanding a mutual lack of interest in this point.
Rawls: Impartiality, as demanded by moral judgments, can be achieved by other means.
