Men followed the words,—such words as "a priori ideas," "forms of perception and thought existing in consciousness independently of experience," "fundamental conceptions of the pure understanding," &c., — and asked whether Plato's Ideas, which were also original conceptions, and besides this were supposed to be reminiscences of a perception before life of the truly real things, were in some way the same as Kant's forms of perception and thought, which lie a priori in our consciousness. On account of some slight resemblance in the expression of these two entirely different doctrines, the Kantian doctrine of the forms which limit the knowledge of the individual to the phenomenon, and the Platonic doctrine [pg 226] of Ideas, the knowledge of which these very forms expressly deny, these so far diametrically opposed doctrines were carefully compared, and men deliberated and disputed as to whether they were identical, found at last that they were not the same, and concluded that Plato's doctrine of Ideas and Kant's "Critique of Reason" had nothing in common. But enough of this.[45]
