Abstract
Citing Kant, the author defines an idea of reason as a concept of the unconditioned totality of the conditions of the conditioned. A theoretical idea is valid if it conforms to the real; but a practical idea can be justified only by an appeal to the unconditioned obligation to realize it. Having introduced these terms and theses, the author examines the ontological and cosmological arguments as attempts to prove the reality of the ideas. He then argues that the apparent contradiction between the idea of the good and moral failure is overcome by cosmic punishment, forgiveness, and redemption.
