What if doing right begins where getting what you want ends?

In The Critique of Practical Reason, Immanuel Kant asks whether reason can tell us what we ought to do, without appealing to wishes or rewards. His answer places moral law at the center of human freedom. A personal rule must face a demanding test: could it hold as a law for every rational being?

Kant then confronts a harder question. Duty asks us to deserve happiness, but it does not promise that happiness will follow. His argument leads from the categorical imperative to the highest good, and to the place of hope, immortality, and belief in God within his moral philosophy. The challenge is to understand what can guide us when desire cannot.
