The Transcendental Aesthetic, as the "Critique" notes, deals with "all principles of a priori sensibility." As a further delimitation, it "constitutes the first part of the transcendental doctrine of elements, in contrast to that which contains the principles of pure thinking, and is named transcendental logic". In it, what is aimed at is "pure intuition and the mere form of appearances, which is the only thing that sensibility can make available a priori." It is thus an analytic of the a priori constitution of sensibility; through which "Objects are therefore given to us…, and it alone affords us intuitions." This in itself is an explication of the "pure form of sensible intuitions in general is to be encountered in the mind a priori." Thus, pure form or intuition is the a priori "wherein all of the manifold of appearances is intuited in certain relations." from this, "a science of all principles of a priori sensibility [is called the transcendental aesthetic." The above stems from the fact that "there are two stems of human cognition…namely sensibility and understanding."
