Discussing the transcendental dialectic, Kant explains that based on pure categories, understanding produces a priori synthetic judgments, though it fails to bring about unity and connection among them. Therefore, reason contributes to understanding, so that, on one hand, it fosters unity among the dispersed judgments of understanding by establishing three series of categorical, hypothetical and disjunctive syllogisms and, on the other hand, it bestows the maximum unity and extension on the judgments and conditional knowledge of understanding by allowing three ideas of reason, that is soul, world and God at the end of the three syllogisms. God or the ideal of pure reason is considered one of the a priori ideas of the pure reason which comes at the end of the series of the disjunctive syllogisms of reason as a transcendental concept and the ultimate unconditional condition. In this way Kant shows how things are logically constituted in mind. He believes that, as "the sum- total of all realities" or "the sum of all possibilities," the ideal of pure reason is the transcendental material and the precondition for determination of all things. In fact human mind is so wired as to produce everything, it first considers the concept of the ideal of the pure reason that is "the sum- total of all realities or possibilities" as the conceptual constitutive material and then carves out the share of every single concept from this undetermined material by adding negative limitations and negations. The present article seeks to elaborate on the way things are organized in mind, using the a priori concept of ideal of the pure reason.
