Note 701 — Chapter I · THE CLUE TO THE DISCOVERY OF ALL PURE CONCEPTS OF THE UNDERSTANDING
Reading edition
Only in one passage, Rechtslehre, i., Anhang 3, 2, cited by Adickes, op. cit. p. 13, does Kant so far depart from his own orthodoxy as to speak of the possibility of an a priori tetrachotomy. But he never wavers in the view that the completeness of a division cannot be guaranteed on empirical grounds.
