Idealizm transcendentalny w perspektywie Kantowskiego pojęcia realności

The main aim of this paper is to try to answer the question of the nature of Kantian project of the transcendental philosophy. Is it, in real, as Kant by himself says, that his philosophy, as the critic of the pure theoretical reason presupposes, is merely the preparation the ground under the metaphysics, and merely asks the question of the possibility of metaphysics at all, or rather Kant's system of the theoretical philosophy called by Kant as formal or transcendental idealism can be classified as one of the main ontological systems: ontological realism or idealism, in the classical sense. I think the crucial notion, which can help to solve this problem, is the notion of reality used by Kant in several meanings and contexts which I am going to examine in this article.
