The most generally acknowledged mode of apprehending God or argument for his existence, is the Moral. The argument has various forms, of which the more commonly accepted and influential, in its main principles, is that of Kant. Kant emphatically rejected the traditional arguments for the existence of God — the Ontological, Cosmological, and Teleological — as inadequate and invalid. More generally, he rejected or greatly subordinated the theoretical reason in the sphere of religion, and gave primacy to the practical or moral reason. He went far in teaching that the sphere of science and the sphere of religion are separate and independent of each other.
