Immanuel Kant

1724-1804 CEPhilosopher

German philosopher who critiqued reason, unified rationalism and empiricism, and grounded morality in duty.

Overview

Immanuel Kant (1724-1804) was a German philosopher who synthesized rationalism and empiricism into a definitive framework for Western thought. Living his entire life in Königsberg, he maintained a legendary schedule while producing revolutionary works. His masterpiece, *The Critique of Pure Reason*, argued that the mind actively structures experience through space, time, and categories rather than passively receiving data.

This 'Copernican revolution' limited knowledge to phenomena, or things as we perceive them, rather than 'things-in-themselves.' In ethics, Kant’s *Groundwork* proposed the Categorical Imperative, the principle that one should act only on maxims that could be universal laws and treat humanity as an end rather than a means.

His work grounded morality in autonomous duty and reason rather than consequences. Kant’s critical project remains a foundational pillar for modern epistemology, metaphysics, and political theory, defining the bounds of human understanding and the requirements of moral agency.
