Abstract

KANT IS, TO BORROW ONE OF HIS OWN METAPHORS, the keystone of the modern defense of religion. This defense turns on the contention that religion is not to be understood in terms of its own metaphysical claims--the most notable being that God exists--for this claim, as well as the obvious counterclaim, cannot be demonstrated. The existence of God is an antinomy--a claim that theoretical reason can neither prove nor disprove. Religion, however, can be, indeed must be defended, because of the claims that a completely dispassionate, even irreligious, reason must make consequent to an analysis of morality. If we understand the nature of duty, conscience, and the moral law, and the end or good to which the moral law obligates us, we will conclude, Kant argues, that we must accept the existence of God as a postulate of practical reason. Kant's defense of religion rests on a strategy that aims to prove the limits of theoretical reason and the necessity of assuming the primacy of practical reason.
