The aim of Kant on one hand is to explain that it is impossible not to perceive objects as an independent existing reality. On the other hand, to prove that, their independent existence is unreal, because, everything that is perceptive can’t without that a subject. At the same time proceeding from the formal conditions of perception, Kant defends even the idea that phenomena exist independently, they posses reality and are not ghosts, because every phenomenon has empiric reality. Due to this we see a sharp difference between the independent existence of object and the existence of phenomena out of us. The existence of phenomena out of subject is the basis of the possibility for the perception of the object by the subject, which is preconditioned by space as an a priori form of perception.
