In the Critique of Pure Reason , Immanuel Kant laid out a framework upon which the whole of modern philosophy is based. This Penguin Classics edition is translated from the German and edited with an introduction by Marcus Weigelt, based on the translation by Max Muller. Kant's Critique of Pure Reason . It presents a profound and challenging investigation into the nature of human reason, its knowledge and illusions. Reason, Kant argues, is the seat of certain concepts that precede experience and make it possible, but we are not therefore entitled to draw conclusions about the natural world from these concepts. The Critique 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. Kant's transcendental idealism indicates a third way that goes far beyond these alternatives. 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.
