Note 673 — Chapter I · THE CLUE TO THE DISCOVERY OF ALL PURE CONCEPTS OF THE UNDERSTANDING

Kant’s definition of transcendental logic as differing from general logic in that it does not abstract from a priori content must not be taken as implying that the categories of understanding are contents, though of a priori nature. As we shall find, though that is Kant’s view of the forms of sense, it is by no means his view of the categories. They are, he repeatedly insists, merely functions, and are quite indeterminate in meaning save in so far as a content is yielded to them by sense. In A 76-7 = B 102, in distinguishing between the two logics, Kant is careful to make clear that the a priori content of transcendental logic consists exclusively of the a priori manifolds of sense.
