Abstract

IN THE FIRST EDITION TRANSCENDENTAL DEDUCTION of the categories Kant does not mention the logical functions of judgment. In the second edition the Deduction can be said to be dominated by the logical functions of judgment. A transcendental deduction supplies a method for showing that pure concepts can have applicability. My contention is that the two deductions constitute exactly the same method, and so are the exact same deduction. The difference between them, rather, is in the characterization of the pure concepts that the method is supposed to be a method for. The undifferentiated categories of the A edition become the logical functions together with their schemata in the B edition. This does not mean that Kant has split the A edition notion of categories since the A edition categories are equivalent to just the schemata themselves.
