Immanuel Kant (1724-1804) was a German philosopher who is considered one of the most important figures in Western philosophy. His work, particularly his Critique of Pure Reason, had a profound impact on various fields such as epistemology, metaphysics, ethics, and aesthetics. Kant’s philosophy aimed to reconcile rationalism and empiricism, and he introduced the concept of transcendental idealism. He also developed the moral theory of deontological ethics, which emphasizes the importance of duty and moral obligations. Kant’s ideas continue to be influential and widely studied in philosophy today.
