Note 10 — INTRODUCTION

One of the various pretended contradictions in this whole distinction of the causality of nature from that of freedom is this. It is objected that if I speak of obstacles which nature opposes to causality according to (moral) laws of freedom or of the assistance it affords, I am admitting an influence of the former upon the latter. But if we try to understand what has been said, this misinterpretation is very easy to avoid. The opposition or assistance is not between nature and freedom, but between the former as phenomenon and the effects of the latter as phenomena in the world of sense. The causality of freedom itself (of pure and practical Reason) is the causality of a natural cause subordinated to freedom (i.e. of the subject considered as man and therefore as phenomenon). The intelligible, which is thought under freedom, contains the ground of the determination of this [natural cause] in a way not explicable any further (just as that intelligible does which constitutes the supersensible substrate of nature).
