Summary

German philosopher — author of the Critique of Pure Reason, Groundwork of the Metaphysics of Morals, and Critique of Judgment — who created the Copernican Revolution in philosophy (that mind structures experience rather than simply receiving it) — whose categorical imperative is the most influential deontological ethics.

Core Contribution

Creates the categorical imperative and the transcendental idealism — Kant's argument (that we should act only according to maxims we could universalize as laws for all rational beings) is the most rigorous deontological ethical framework; his transcendental idealism (that space and time are forms of intuition not features of things-in-themselves) restructured metaphysics.

Key Spikes & Highlights

  • Was so punctual that the people of Königsberg reportedly set their clocks by his daily walk — at the same hour, along the same route; his life combined maximum intellectual ambition with maximum personal regularity; the person who restructured Western philosophy lived in the most conventionally ordered way imaginable
  • Woke from 'dogmatic slumber' by reading Hume — his account of how Hume's problem of causation forced him to rethink the foundations of knowledge is the most famous intellectual conversion in the history of philosophy, producing the three Critiques that define modern philosophy's agenda
