The relationship between Kant and Rawls is apparently an obvious one; Rawls himself acknowledges the Kantian foundations of his approach to questions of justice and political right, and identifies the precise points at which his theory departs from that of Kant. This essay attempts to show that when one examines those points of departure carefully, they turn out to point not merely away from Kant, but directly and inexorably toward the account of political right given by Rousseau in The Social Contract. The essay argues that it is impossible to fully understand Rawls' theoretical project until one sees the (unstable) position it occupies between the Kantian and Rousseauian accounts of political right. Moreover, it argues that the theoretical project undertaken by Rawls, that of revising the Kantian conception of autonomy in an attempt to show how it could be coherently “expressed” politically, was actually undertaken and “completed” by Rousseau — though with ironic, and unsettling, results.
