ABSTRACT
Kant's exposure of the illusions of rational psychology is both brilliant and profound. It is philosophical criticism of the highest order. Yet it must be confessed that the development of the thought in the text is often dark and involved; and much of its obscurity is due to a certain incompleteness in the exposure, an inadequate consideration of a matter of central importance. I begin by noting, crudely and briefly, (I) the nature of the doctrine to be attacked, (z) the main line of Kant's attack upon it, and (3) the diagnosis which Kant offers of the sources of the illusion. Then I proceed to explain and elaborate and, where necessary, to criticize and to supplement, Kant's doctrine.
