ABSTRACT
One of the major arguments for the rationality of religious belief in contemporary systematic theology is based on Kant's postulate of the existence of God. The Kantian argument relies heavily on certain assumptions about the unconditionality of human morality. In this article, I assess the impact of a ‘natural history of human morality’ provided by Tomasello on Kant's argument for the existence of God. I argue that Tomasello's account of human morality and his view on the evolution of religion strengthen the appeal of Kant's postulates by providing empirical support for a Kantian understanding of morality and religion. At the same time, both Kant and Tomasello have a blind spot in that they assume a connection between religion and morality which is too close. The existential dimension of religious faith is neglected by both thinkers, and there is more research needed on the evolution of religion, which focuses on its existentialist deep structure.
