In the Transcendental Analytic Kant will argue that all conscious representations, including sense perceptions, must have both sensible and intellectual aspects. But his theory of judgment prevents him from proceeding in this manner. Critique of Pure Reason (German: Kritik der reinen Vernunft 1781 second edition 1787) is a book by the German philosopher Immanuel Kant, in which the author seeks to determine the limits and scope of metaphysics. Unfortunately this leaves the impression that Kant's arguments are based on premises concerning the a priori data of sensibility.

To accomplish this task, he must isolate the sensibility from the intellect, and then, within sensibility, separate a posteriori from a priori elements. Kant says at A22/B36 that the Transcendental Aesthetic will examine the sensibility, to determine whether it contributes a priori knowledge to experience. Although Kant does not identify his targets, thinkers such as Descartes, Locke, Berkeley, Newton, and Leibniz held opposing theories of both the ontological status of space and time, and our knowledge of them. These conclusions are based on profound arguments concerning the nature of space and time cognition. The main part of CPR is difficult to digest. He gives a good introduction to the problem and his solution. In Immanuel Kant's Critique of Pure Reason is a reconstruction of the then predominant school of skeptical empiricism, which typified almost all of seventeenth-century European philosophy from.

Thus in the Transcendental Aesthetic Kant takes an important step in establishing the unknowability of things in themselves. Reading only Kants own 'Preface to the second edition' of the Critique of Pure Reason (CPR) is rewarding, even without knowing any other philosophical work. Because these forms are part of the subject's sensibility, he will further conclude that space and time are transcendentally ideal, although they are also empirically real. Kant will argue in the Transcendental Aesthetic that human subjects have two pure forms of intuition, space and time, which are the source of synthetic a priori knowledge of mathematics and mechanics.
