 Although Kant enumerates three postulates, freedom, God, and immortality, their etiologies differ. In contrast to the latter two, the postulate of freedom is more directly tied to the fact of reason, taken as a necessary condition for the bindingness of the moral law upon us. By contrast, the postulates of God and Immortality are rooted in the highest good. As such, we will here only be concerned with the latter two “religious” postulates.
