Instead of which one false doctrine is built up on the other.

The inadmissibility of a basis for Morals consisting of a few entirely abstract and empty conceptions must have been apparent to Kant himself in secret. For in the Kritik der Praktischen Vernunft, where (as I have already said) he is not so strict and methodical in his work, and where we find him becoming bolder on account of the fame he had gained, it is remarkable how the ethical basis gradually changes its nature, and almost forgets that it is a mere web of abstract ideas; in fact, it seems distinctly desirous of becoming more substantial. Thus, for instance, on p. 81 (R., p. 163) of the above work are the words: “The Moral Law in some sort a fact of Pure Reason.” What is one to think of this extraordinary expression?
