Note 570 — THE TRANSCENDENTAL AESTHETIC SECTION II TIME METAPHYSICAL EXPOSITION OF THE CONCEPTION OF TIME
Reading edition
When Kant says that the distinction is not logical (that of relative clearness and obscurity) but transcendental, the latter term is taken as practically equivalent to epistemological. It does not mean ‘relating to the a priori,’ but relating to transcendental philosophy, just as logical here means relating to logic. Cf. Vaihinger, ii. p. 452.
