Kant is a pivotal thinker in Adorno's intellectual world. Yet although he wrote monographs on Hegel, Husserl and Kierkegaard, the closest he came to an extended discussion of Kant are two lecture courses, one concentrating on the Critique of Pure Reason, and the other on the Critique of Practical Reason. This volume by Adorno comprises his lectures on the former. Adorno attempts to make Kant's thought comprehensible to students by focusing on what he regards as problematic aspects of Kant's philosophy. Adorno examines his dualism and what he calls the Kantian block: the contradictions arising from Kant's resistance to the idealism that his successors, Fichte, Schelling and Hegel, saw as the inevitable outcome of his ideas. But these lectures also provide an accessible introduction to and rationale for Adorno's own philosophy as expounded in Negative Dialectics and his other major writings. Adorno's view of Kant forms an integral part of his own philosophy, since he argues that the way out of the Kantian contradictions is to show the necessity of the dialectical thinking that Kant himself spurned.
