Kant’s “Critique of Practical Reason,” published in 1788, is the second of his three major critiques. While the first critique focuses on knowledge, this work explores how humans should act. It is a cornerstone of ethical philosophy, introducing the idea that morality is grounded in reason rather than emotion or consequences.
Kant believed that true moral actions come from a sense of duty, not from personal desires or expected outcomes. This idea contrasts sharply with other ethical theories like utilitarianism, which focuses on maximizing happiness.

Kant’s philosophy revolves around several core ideas that define ethical reasoning. Understanding these concepts is essential for interpreting the entire work.
Kant argues that the only intrinsically good thing is the good will. Actions are morally right not because of their results, but because of the intention behind them.
Moral actions are those performed out of duty, not inclination. For example, helping someone because it is right—not because you feel like it—is a moral act.
Autonomy means self-governance. Humans are morally responsible because they can create and follow moral laws using reason.
| Term | Meaning | Example |
|---|---|---|
| Duty | Acting according to moral law | Helping others even when inconvenient |
| Inclination | Acting based on feelings | Helping because you like someone |
