Kantian Imperative — Duty

"Act only on a rule you would want all to follow"

Immanuel Kant · 18세기

💡 TL;DR

Kantian Imperative — Duty — "Act only on a rule you would want all to follow". Kant's categorical imperative lifted the Golden Rule one level.

📜 Origin

Kant of Königsberg never left his city. He walked the same route at the same hour, so neighbors set their clocks by him. Yet on his small desk, the history of human thought turned. He asked — what is morality? Good consequences? Divine command? No. Only one test: "Can I will that the rule of my action become a universal law?" If not, the action is not moral.

💡 Meaning

Kant's categorical imperative lifted the Golden Rule one level. Not "be kind to others" but "act so that the rule of your kindness could be a universal law." Morality is neither consequence nor emotion but form — the form that holds for all.

🌏 Eastern Classic Cross-link

Analects: "Do not impose on others what you do not want." 2,300 years before Kant. Confucius's Golden Rule says "see others as yourself"; Kant adds, "verify the universality." Both climbed the same mountain; Kant sharpened the formal view from its summit.

Compressed into One Hanja

"義" = 羊 (sheep) + 我 (I) — "a sheep above my head," the sacrificial posture. 義 is: follow the right even at cost to self. Kant's duty wears the same posture — whatever the outcome, if the form is right, act.

🌐 Modern Application

The universality principle of modern rule of law, patient autonomy in medical ethics, declarations of human rights, and the universal standard behind civil-disobedience movements.

⚠️ Caveat

The danger of "rule absolutism" — even Kant agonized over what to do when a lie could save a life.
