Immanuel Kant

About this figure

Immanuel Kant (1724-1804) was a German philosopher who spent virtually his entire life in the East Prussian city of Konigsberg, where he rose from modest origins to become one of the most systematically influential thinkers in the history of philosophy. Kant studied and later taught at the University of Konigsberg, eventually holding the chair of logic and metaphysics there, and he was known for the disciplined regularity of his daily habits, though the popular story that Konigsberg residents set their clocks by his afternoon walks is difficult to verify and may be embellished.

After decades of relatively conventional academic work, Kant published the Critique of Pure Reason in 1781, revising it substantially for a second edition in 1787. The book attempted to determine the scope and limits of human reason, arguing that the mind actively structures experience through inbuilt forms of intuition, such as space and time, and categories of understanding, so that knowledge arises from the interaction of these structures with sensory data rather than from experience or reason alone. The Critique of Pure Reason was followed by the Critique of Practical Reason, on ethics, and the Critique of Judgment, on aesthetics and teleology, together forming the core of what is generally called Kant's critical philosophy. His ethical writings, including the Groundwork of the Metaphysics of Morals, introduced the concept of the categorical imperative as a test of moral duty.

Kant never married and never traveled far from Konigsberg, but his university lectures and correspondence connected him to the broader intellectual currents of his time. He died in Konigsberg in 1804.
