Groundwork of the Metaphysics of Morals

What is faith? Is it only what we feel with the soul—intuitively—but cannot prove? Or can belief in a higher essence be grounded in knowledge?

The classic of philosophical thought, the great Immanuel Kant, took on the most difficult task: to prove through logical reasoning that God exists. Without a rational creative principle, the philosopher argues, nature could not have such a perfect arrangement. He doesn’t just prove—it invites the reader to reflect. And more than two hundred fifty years later, Kant’s work still doesn’t stop sparking interest.
