ABSTRACT
Immanuel Kant calls some object of pure thought an Idea of Pure Reason, or a Transcendental Idea, in that it is a rational unity or product Reason supplies out of itself, no object ever being found to correspond to it in the world of sense. The Ideas of pure reason is the rational conception of the soul as the absolute unity of the thinking self, and in the division of the Dialectic Kant is mainly concerned with the Idea or unconditioned unity. In Rational Psychology, an attempt is made not only to think of the unity of self independent of what it unites, but as itself constituting an object of knowledge. All the assertions of Rational Psychology are so many paralogisms, arising from an illegitimate application of the category of substance to the consciousness.
