Kant, History, and the Idea of Moral Development

I examine the consistency of Kant's notion of moral progress as found in his philosophy of history. To many commentators, Kant's very idea of moral development has seemed inconsistent with basic tenets of his critical philosophy. This idea has seemed incompatible with his claims that the moral law is unconditionally and universally valid, that moral agency is noumenal and atemporal, and that all humans are equally free. Against these charges, I argue not only that Kant's notion of moral development is consistent, but also that the assumption of the possibility of moral progress is indispensible for Kant's moral theory.
