Religion Within the Boundaries of Mere Reason

“Kant asks what remains of Christianity when it is read by reason alone. He finds in human nature a 'radical evil' — a propensity to put self-love above the moral law — that can be overcome only by a revolution of the heart; reads the Son of God as the ideal of moral perfection in our reason; describes the church as an 'ethical commonwealth' on the way to a pure religion of reason; and condemns as 'counterfeit service' every attempt to please God by anything except a good life.”
