Kant’s religious ethics: the ineluctable link between morality and theism

Kant’s religious ethics is grounded in a practical philosophy where ‘God’ is subordinated to moral principles. To accomplish this goal, Kant dismantled the onto-theological groundwork of religion and the conventional method of attaching morality to God, as if morality was a consequence of religious belief. In this essay, I will show how Kant replaces the metaphysics of being with the metaphysics of morality. More importantly, I will show how Kant’s thesis of moral theism argues that the practical philosophy does not end with the categorical imperative, but that Kant also thinks morality inevitably leads to religious belief.
