Kant's theory of justice continues to exert a powerful influence on contemporary discussions of justice and equality. Modern theorists disagree, however, regarding the implications of Kant's theory for the state's responsibility for public welfare. A traditional interpretation holds that Kant's political theory simply constitutes an account of the constraints which reason places on the state's authority to regulate external action. Alexander Kaufman argues that this traditional interpretation succeeds neither as a faithful reading of Kant's texts nor as a plausible, philosophically sound reconstruction of a 'Kantian' political theory. Rather he argues that Kant's political theory articulates a positive conception of the state's role. In particular, Kantian justice requires that each member of society must be guaranteed the opportunity to realize his or her purposive capacities. In order to secure this guarantee, Kantian justice requires interventions to ensure equality of capabilities.
