The masterpiece of the father of modern philosophy A seminal text of modern philosophy, Immanuel Kant's Critique of Pure Reason (1781) made history by bringing together two opposing schools of thought: rationalism, which grounds all our knowledge in reason, and empiricism, which traces all our knowledge to experience. Published here in a lucid reworking of Max Müller's classic translation, the Critique is a profound investigation into the nature of human reason, establishing its truth, falsities, illusions, and reality.
