Note 99 — Chapter VIII

The main passage (B. 146-9, M. 90-2), in which he argues that the categories do not apply to things in themselves, ignores the account of a conception as a principle of synthesis, upon which the deduction turns, and returns to the earlier account of a conception as something opposed to a perception, i. e. as that by which an object is thought as opposed to a perception by which an object is given. Consequently, it argues merely that the categories, as conceptions, are empty or without an object, unless an object is given in perception, and that, since things in themselves are not objects of perception, the categories are no more applicable to things in themselves than are any other conceptions.
