Return to Kant, Immanuel

The arch-advocate of “duty” is Immanuel Kant; he went so much farther than other theorists that they seem innocently benevolent by comparison. “Duty,” he holds, is the only standard of virtue; but virtue is not its own reward: if a reward is involved, it is no longer virtue. The only moral motivation, he holds, is devotion to duty for duty’s sake; only an action motivated exclusively by such devotion is a moral action (i.e., an action performed without any concern for “inclination” [desire] or self-interest).

“It is a duty to preserve one’s life, and moreover everyone has a direct inclination to do so. But for that reason the often anxious care which most men take of it has no intrinsic worth, and the maxim of doing so has no moral import. They preserve their lives according to duty, but not from duty. But if adversities and hopeless sorrow completely take away the relish for life, if an unfortunate man, strong in soul, is indignant rather than despondent or dejected over his fate and wishes for death, and yet preserves his life without loving it and from neither inclination nor fear but from duty—then his maxim has a moral import” (Immanuel Kant, Foundations of the Metaphysics of Morals, ed. R. P. Wolff, New York, Bobbs-Merrill, 1969, pp. 16–17).
