Abstract
The paper investigates some principles of transcendental realism and their role in the third antinomy of the Critique of Pure Reason. We try to show that things and representations, as well as distinctive types of faculties, are differently confl ated according to diff erent ways in which space and time are said independent of our sensibility. We try to explain the diff erent claims of partisans of thesis and antithesis in the third antinomy based on these different ways in which things and representations, and cognitive principles, collapse.
