Based on Transcendental Idealism, Reflecting on the Rejection of Kant's Transcendental Metaphysics

A priori concepts، according to Kant، are used just for the objective or the experienced phenomenon، and applying them for the others (non-empirical or as Kant calls it the “noumena”، the “things-in-themselves،” or (elsewhere) the “transcendental objects”) are not valid. Unlike Kant، in Newtonian physics، they can be used both for experienced and non- experienced phenomenon. Comparing with what was developed by Nicolas Copernicus in Cosmology in the 16th century، Kant calls his viewpoint as a “Copernican Revolution” that happened in the philosophy. In the framework of Critical philosophy، Kant tries to explain and defend from his epistemological revolution. Here، firstly، I will argue that، Kant''s premises of judgment (assuming their correctness) do not entail the transcendental Idealism، and secondly، Kant''s Copernican revolution is not a perspective in the frame of critical philosophy but it is a kind of transcendental metaphysics.
