Immanuel Kant
1724–1804 · German philosopher of the Critique of Pure Reason and the categorical imperative.
Immanuel Kant was born in Königsberg, in East Prussia, the son of a harness maker, and was raised in a devout Pietist Lutheran household. He studied at the university there and worked for years as a private tutor and lecturer before becoming professor of logic and metaphysics in 1770. He never traveled far from his home city, and his daily walks were said to be so regular that neighbors set their clocks by them. Reading David Hume, he said, woke him from his dogmatic slumber. In the Critique of Pure Reason, published in 1781, he argued that the mind does not simply receive the world but shapes experience through built-in forms such as space, time and cause, and that reason cannot prove things beyond all possible experience. In his moral philosophy he taught the categorical imperative: act only on a rule you could will to be a law for everyone, and treat people always as ends, never merely as means. He also wrote on science, religion, beauty, history and lasting peace among nations. He died in Königsberg in 1804.
