Immanuel Kant (1724–1804) was a German philosopher whose work profoundly influenced modern philosophy. Born in Königsberg (now Kaliningrad, Russia), Kant developed a comprehensive philosophical system that sought to reconcile the rationalism of Descartes and Leibniz with the empiricism of Locke and Hume. His critical philosophy, especially in *The Critique of Pure Reason*, established the framework for modern metaphysics and epistemology, focusing on the limits and structures of human cognition. Kant’s theories on moral philosophy (*The Critique of Practical Reason*), aesthetics (*The Critique of Judgment*), and political theory remain central to contemporary philosophical discourse.
