 While Kant holds that morality’s foundation is independent of religion, the two are more closely connected for him than they are for Hume. Compared with Hume, Kant is far less antagonistic to religion, and he consistently tries to preserve a place for religious belief within the strictures of his moral philosophy. Indeed, this is an important aspect of his approach to morality. Kant’s “moral theism” is one of his most significant contributions to the philosophy of religion and the question of religion’s relation to morality. Moral theism is belief in God founded on morality. By belief (or faith) [Glaube], Kant means something different from knowledge [Wissen] (A 822/B 850; WOT 8:140–41). Believing and knowing both involve holding something to be true. When one knows something, one holds it to be true on grounds that are “subjectively and objectively” sufficient, whereas when one believes something, one holds it to be true on grounds that are subjectively but not objectively sufficient (A 822/B 850). Here, Kant takes objective sufficiency to imply valid theoretical grounds, such as evidence or theoretical argument; he takes subjective sufficiency, by contrast, to imply valid practical grounds. Thus, belief entails having valid practical reasons for holding something to be true, while lacking valid theoretical reasons for doing so. Indeed, when it comes to belief in God, Kant does not think that knowledge is possible (CPJ 5:471–72).
