Abstract
The bulk of Kant's Critique of Pure Reason is divided, in its philosophical content if not its formal organization, into two parts. The first, encompassing the Introduction, the Aesthetic and the Transcendental Analytic, presents a theory of metaphysical knowledge; its source and nature, its proper objects, and its fundamental principles. The second part, contained in the Transcendental Dialectic, is a theory of metaphysical error, illusion, or pseudoknowledge. For various reasons, students of the Critique have tended to neglect the second part of Kant's project in favor of the first, though there is no evidence that Kant himself regarded it as less important or less essential to the critical philosophy.
