A long-awaited reissue of Immanuel Kant’s celebrated work. Immanuel Kant is the founder of German classical philosophy and one of the central thinkers of the Enlightenment. In «The Proof of the Existence of God», the great philosopher critiques five arguments for God’s existence by Thomas Aquinas and formulates his own, a sixth—one that, until now, no one has been able to logically refute. The collection also includes «Religion within the Limits of Reason Alone». From Kant’s point of view, God is the highest Being—a moral and ethical postulate—and religion is the recognition and fulfillment by a person of moral duties as God’s commandments.
