How does Kant argue in support of transcendental idealism in the “Transcendental Aesthetic” and how is this related to the passage BXVI of the preface to the second edition of the Critique (the “Copernican Turn”)? In the Preface to the second edition of The Critique of Pure Reason Immanuel Kant observes that, “If after many preliminaries and preparations are made, a science gets stuck as soon as it approaches its end, or if in order to reach this end it must often go back and set out on a new path…then we may be sure that such study merely groping about, that it is still far from having entered upon a course of science… ”(Bvii-Bviii). He is referring here to the study of metaphysics. Kant underlines his belief that the study of this subject so far has not been conclusive or productive in explaining how knowledge is given to us because of the approach taken by his contemporaries. In the Critique Kant introduces his doctrine of transcendental idealism in an attempt to solve what he believes to be this great problem in the study of metaphysics. Kant’s doctrine was inspired by the revolutionary work of scientist Nicolas Copernicus. In an attempt to understand celestial motion Copernicus decided that if he could not come up with an explanation by the traditional methods, he would turn the science on its head. So, instead of having the celestial body revolving around the earth, he decided that the earth would revolve and the stars would be left as they were. Kant applies this “Copernican Revolution/Turn” to the study of metaphysics, by looking at the subject from a completely different angle in his doctrine of transcendental idealism in the Critique. Transcendental idealism is concerned with the distinction between appearances and things in themselves. Kant believes we cannot have knowledge of things as they are in themselves, only of how they appear to us.
