Aristotle, Kant and Rawls on Moral Motivation in a Just Society

John Rawls considers his Theory of Justice to be in the Kantian tradition. Generally there seems to be agreement among Rawls' critics that at least with respect to the procedural formulation of the principles of justice, it is difficult to call Rawls' position Kantian. In this article I will argue that Rawls' Kantianism is best understood as providing a motive source for acting upon known just standards of conduct. In this regard Rawls can be read as synthesizing aspects of Aristotle's Nicomachean Ethics and Kant's moral reasoning to provide the rationale to explain why an individual who knows what is morally correct conduct in a given situation, makes such knowledge the source of his action. Demonstrating the Aristotelean roots of Rawls' Kantianism with respect to the problem of motivation for just conduct helps one understand how Kant's moral theory can be viewed in Rawls' words not as a “morality of austere command but … [as] … an ethic of mutual respect and self esteem†(1971, p. 251). Secondly, this view of Kant provides the basis for understanding the anti-corporatist aspect of Rawls' political theory that my reading of Rawls makes necessary.
