After identifying contrasting formulations of the practical postulates of reason in Kant's second critique, I analyse the context of each formulation, showing both how the postulate of the ‘possibility’ of God is consistent with Kant's understanding of a significant transition arising from practical needs as well as how the postulate of the existence of God can be seen as a ‘practical belief’ acting out a ‘hope’. My goal is to re-examine Kant's view of the relation between the practical and theoretical employments of reason in order to distinguish clearly between what Kant sees as required of the moral believer as opposed to permitted.
