Now there are two reasons why these gentlemen "in the philosophical trade"--as they call themselves with incredible _naïveté_--hate my philosophy. The first of them is, that my writings spoil the taste of the public for tissues of empty phrases, for accumulations of unmeaning words piled one upon another, for hollow, superficial, brain-racking twaddle, for Christian dogmatics under the disguise of the most wearisome Metaphysics, for systematized Philistinism of the flattest kind made to represent Ethics and even accompanied by instructions for card-playing and dancing--in short, they unfit my readers for the whole method of philosophising _à la vieille femme_, which has scared so many for ever from the pursuit of philosophy.

The second reason is, that our gentlemen "in the trade" are absolutely bound in conscience not to let my philosophy pass and are therefore debarred from using it for the benefit of "the trade;"--and this they even heartily regret; for my abundance might have been admirably turned to account for the benefit of their own needy poverty. But even if it contained the greatest hoards of human wisdom ever unearthed, my doctrine could never find favour with them either now or in the future; for it is absolutely wanting in all Speculative Theology and Rational Psychology, and these, just these, are the very breath of life to these gentlemen, the _sine qua non_ of their existence. For they are anxious before all things in heaven and on earth, to hold their official appointments, and these appointments demand before all things in heaven and on earth a Speculative Theology and a Rational Psychology: _extra hæc non datur salus_. Theology there must and shall be, no matter whence it come; Moses and the Prophets must be made out to be in the right: this is the highest principle in philosophy; and there must be Rational Psychology to boot, as is proper. Now there is nothing of the sort to be found either in Kant's philosophy or in mine. For, as we all know, the most cogent theological argumentation shivers to atoms like a glass thrown at a wall, when it is brought into contact with Kant's Critique of all Speculative Theology, and under his hands not a shred remains entire of the whole tissue of Rational Psychology! As to myself, being the bold continuer of Kant's philosophy, I have entirely done away with all Speculative Theology and all Rational Psychology, as is only consistent and honest.[170] On the other hand, the task incumbent upon University Philosophy is at bottom this: to set forth the chief fundamental truths belonging to the Catechism under the veil of some very abstract, abstruse and difficult, therefore painfully wearisome formulas and sentences; wherefore, however confused, intricate, strange and eccentric the matter may seem at first sight, these truths invariably reveal themselves as its kernel. This proceeding may be useful, though to me it is unknown. All I know is, that philosophy, _i.e._ the search after truth--I mean the truth κατ' ἐξοχήν, by which the most sublime and important disclosures, more precious than anything else to the human race, are understood--will never advance a step, nay, an inch, by means of such manœuvring, by which its course is on the contrary impeded; therefore I found out long ago that University philosophy is the enemy of all genuine philosophy. Now, this being the state of the case, when a really honest philosophy arises, which seriously has truth for its sole aim, must not these gentlemen "of the philosophical trade" feel as might stage-knights in paste-board armour, were a knight suddenly to appear in the midst of them clad in real armour, who made the stage-floor creak under his ponderous tread? Such philosophy as this _must_ therefore be bad and false and consequently places these gentlemen "of the trade" under the painful obligation of playing the part of him who, in order to appear what he is not, cannot allow others to pass for what they really are. Out of all this however there unrolls itself the amusing spectacle we enjoy, when these gentlemen, now that ignoring has unfortunately come to an end, after forty years, at last begin to measure me by their own puny standard and pass judgment upon me from the heights of their wisdom, as though they were amply qualified to do so by their office; but they are most amusing of all when they assume airs of superiority towards me.
