This is a book by the famous German philosopher in which he seeks to determine the limits and scope of metaphysics, the basic message being that when philosophers thought they were describing the actual nature of things, they were wrong and this critique is felt to be the central text of modern philosopy. It presents a profound and challenging investigation into the nature of human reason , its knowledge and its illusions. Often called “Kant’s First Critique” it is a dense read and not for the faint-hearted despite its importance for modern philosophy.
