Note 1213 — Chapter II · SYSTEM OF ALL PRINCIPLES OF PURE UNDERSTANDING
Reading edition
Kant’s phenomenalist substitute for the Cartesian subjectivism (cf. above, pp. 270 ff., 312 ff.) enables him to develop this thesis in a consistent and thoroughgoing manner. The subjective is a subspecies within the class of what is determined by natural law; and the principle of causality is therefore applicable to subjective change in the same rigorous fashion as to the objectively sequent.
