Kant's Critique of Pure Reason (1781) is the central text of modern philosophy. It brings together the two opposing schools of philosophy: rationalism, which grounds all our knowledge in reason, and empiricism, which traces all our knowledge to experience. The Critique is a profound and challenging investigation into the nature of human reason, establishing its truths and its falsities, its illusions and its reality. Reason, argues Kant, is the seat of all concepts, including God, freedom and immortality, and must therefore precede and surpass human experience. Marcus Weigelt's lucid re-working of Max Muller's classic translation makes the critique accessible to a new generation of readers. His informative introduction places the work in context and elucidates Kant's main arguments. This edition also contains a bibliography and explanatory notes.
