Undergraduate students of philosophy are often told that Immanuel Kant is famous for teaching that 'ought implies can', and furthermore that this principle implies that it makes no sense to tell someone that they ought to do something if they do not have the ability to execute the action in question. Kant's views on the reciprocality of obligation and moral freedom, it is reasonable to attribute to Kant the view that ought implies moral freedom. Hud Hudson believes that there are many positive virtues of the methodological reading of Kant. Moreover, he is convinced that the two-worlds reading of Kant is problematic. Salient portions of Kant's philosophy appear to deny what PAP and a normal understanding of the principle of 'ought implies can' entails, namely that morally free agents necessarily have it in their power to actualise alternative possibilities, and specifically the possibility that consists in the actualisation of what an obligation entails.
