Immanuel Kant, born April 22, 1724, in Königsberg, then part of Prussia, is one of the most influential philosophers in the history of Western philosophy. His comprehensive and systematic work in epistemology (the theory of knowledge), ethics, and aesthetics greatly influenced all subsequent philosophy, especially the various schools of Kantianism and idealism. Kant's endeavor to set out to the limits of metaphysics and understanding led to what is often considered his greatest work, 'The Critique of Pure Reason' (1781/1787), establishing his reputation as a foremost thinker. His 'The Critique of Practical Reason' (1788) is central in his moral philosophy, whilst 'The Critique of Judgment' (1790), the third of his seminal triad, delves into aesthetics and teleology. It bridges the gap between the natural world and the moral world, providing a comprehensive framework for his aesthetic theory, notably his analyses of beauty and the sublime. Kant's critical style of philosophy was aimed at solving what he perceived as shortcomings of past doctrines, setting the stage for many philosophical debates that would follow. He passed away on February 12, 1804, in Königsberg, where he had lived all his life, but his writings continue to resonate and shape philosophical discussion today.
