Immanuel Kant

1724 – 1804 · Königsberg · Enlightenment

The punctual professor who synthesized empiricism and rationalism: we know appearances structured by our own minds — and morality begins with duty.

Core ideas

  • The mind actively structures experience; we know things as they appear
  • Act only on maxims you could will as universal law
  • Treat humanity, in yourself and others, always as an end

Historical context

Never traveled far from Königsberg, yet reordered the world of ideas — writing quietly through the era of revolution his ethics quietly endorsed.
