Abstract
ant in Critique of Judgment tries to introduce aesthetical judgment as a product of reflective judgment, and he, in the First Critique, separates it from the cognitive judgments of understanding, but in the Second Critique, from the ethical judgments of reason. Because the Third Critique must fill the gap between those two, and thus enable communication between two realms of philosophy, it has to establish a relation between faculties of understanding, reason, and imagination in an aesthetical and a teleological reflective. This paper, introducing the general principles governing on aesthetical reflective judgment and the free play of imagination and understanding for abstraction of pure and final form of objects, wants to justify the relation between imagination and reason in the beauty of art and its two parts, i.e., the mechanical arts, and fine art (genius).
