But where was this falsehood originally hatched? How did the fiction first come into the world? I am bound to confess that it was first originated by Kant's Practical Reason with its Categorical Imperative. For when this Practical Reason had once been admitted, nothing further was needed than the addition of a second, no less sovereign Theoretical Reason, as its counterpart, or twin-sister: a Reason which proclaims metaphysical truths _ex tripode_. I have described the brilliant success of this invention in my Fundamental Problems of Ethics[139] to which work I refer my reader. Now, although I grant that Kant first gave rise to this false assumption, I am, nevertheless, bound to add, that those who want to dance are not long in finding a piper. For it is surely as though a curse lay on mankind, causing them, in virtue of a natural affinity for all that is corrupt and bad, to prefer and hold up to admiration the inferior, not to say downright defective, portions of the works of eminent minds, while the really admirable parts are tolerated as merely accessory. Very few in our time know wherein the peculiar depth and true grandeur of Kant's philosophy lies; for his works have necessarily ceased to be comprehended since they have ceased to be studied. In fact, they are now only cursorily read, for historical purposes, by those who are under the delusion that philosophy has advanced, not to say begun, since Kant. We soon perceive therefore, that in spite of all their talk about Kantian philosophy, these people really know nothing of it but the husk, the mere outer envelope, and that if perchance they may here or there have caught up a stray sentence or brought away a rough sketch of it, they have never penetrated to the depths of its meaning and spirit. People of this sort have always been chiefly attracted, in Kant's Philosophy, first of all by the Antinomies, on account of their oddity, but still more by his Practical Reason with its Categorical Imperative, nay even by the Moral Theory he placed on the top of it, though with this last he was never in earnest; for a theoretical dogma which has only practical validity, is very like the wooden guns we allow our children to handle without fear of danger: properly speaking, it belongs to the same category as: "Wash my skin, but without wetting it." Now, as regards the Categorical Imperative, Kant never asserted it as a fact, but, on the contrary, protests repeatedly against this being done; he merely served it up as the result of an exceedingly curious combination of thoughts, because he stood in need of a sheet-anchor for morality. Our professors of philosophy, however, never sifted the matter to the bottom, so that it seems as if no one before me had ever thoroughly investigated it. Instead of this, they made all haste to bring the Categorical Imperative into credit as a firmly established fact, calling it in their purism "the moral law"--which, by the way,
