The falseness of an opinion is not for us any objection to it: it is here, perhaps, that our new language sounds most strangely. The question is, how far an opinion is life-furthering, life-preserving, species-preserving, perhaps species-rearing, and we are fundamentally inclined to maintain that the falsest opinions (to which the synthetic judgments a priori belong), are the most indispensable to us, that without a recognition of logical fictions, without a comparison of reality with the purely imagined world of the absolute and immutable, without a constant counterfeiting of the world by means of numbers, man could not live—that the renunciation of false opinions would be a renunciation of life, a negation of life. To recognise untruth as a condition of life; that is certainly to impugn the traditional ideas of value in a dangerous manner, and a philosophy which ventures to do so, has thereby alone placed itself beyond good and evil.

That which causes philosophers to be regarded half-distrustfully and half-mockingly, is not the oft-repeated discovery how innocent they are—how often and easily they make mistakes and lose their way, in short, how childish and childlike they are—but that there is not enough honest dealing with them, whereas they all raise a loud and virtuous outcry when the problem of truthfulness is even hinted at in the remotest manner. They all pose as though their real opinions had been discovered and attained through the self-evolving of a cold, pure, divinely indifferent dialectic (in contrast to all sorts of mystics, who, fairer and foolisher, talk of “inspiration”), whereas, in fact, a prejudiced proposition, idea, or “suggestion,” which is generally their heart’s desire abstracted and refined, is defended by them with arguments sought out after the event. They are all advocates who do not wish to be regarded as such, generally astute defenders, also, of their prejudices, which they dub “truths,”—and very far from having the conscience which bravely admits this to itself, very far from having the good taste of the courage which goes so far as to let this be understood, perhaps to warn friend or foe, or in cheerful confidence and self-ridicule. The spectacle of the Tartuffery of old Kant, equally stiff and decent, with which he entices us into the dialectic byways that lead (more correctly mislead) to his “categorical imperative”—makes us fastidious ones smile, we who find no small amusement in spying out the subtle tricks of old moralists and ethical preachers. Or, still more so, the hocus-pocus in mathematical form, by means of which Spinoza has, as it were, clad his philosophy in mail and mask—in fact, the “love of his wisdom,” to translate the term fairly and squarely—in order thereby to strike terror at once into the heart of the assailant who should dare to cast a glance on that invincible maiden, that Pallas Athene:—how much of personal timidity and vulnerability does this masquerade of a sickly recluse betray!

It has gradually become clear to me what every great philosophy up till now has consisted of—namely, the confession of its originator, and a species of involuntary and unconscious autobiography; and moreover that the moral (or immoral) purpose in every philosophy has constituted the true vital germ out of which the entire plant has always grown. Indeed, to understand how the abstrusest metaphysical assertions of a philosopher have been arrived at, it is always well (and wise) to first ask oneself: “What morality do they (or does he) aim at?” Accordingly, I do not believe that an “impulse to knowledge” is the father of philosophy; but that another impulse, here as elsewhere, has only made use of knowledge (and mistaken knowledge!) as an instrument. But whoever considers the fundamental impulses of man with a view to determining how far they may have here acted as inspiring genii (or as demons and cobolds), will find that they have all practiced philosophy at one time or another, and that each one of them would have been only too glad to look upon itself as the ultimate end of existence and the legitimate lord over all the other impulses. For every impulse is imperious, and as such, attempts to philosophize. To be sure, in the case of scholars, in the case of really scientific men, it may be otherwise—“better,” if you will; there there may really be such a thing as an “impulse to knowledge,” some kind of small, independent clockwork, which, when well wound up, works away industriously to that end, without the rest of the scholarly impulses taking any material part therein. The actual “interests” of the scholar, therefore, are generally in quite another direction—in the family, perhaps, or in moneymaking, or in politics; it is, in fact, almost indifferent at what point of research his little machine is placed, and whether the hopeful young worker becomes a good philologist, a mushroom specialist, or a chemist; he is not characterised by becoming this or that. In the philosopher, on the contrary, there is absolutely nothing impersonal; and above all, his morality furnishes a decided and decisive testimony as to who he is—that is to say, in what order the deepest impulses of his nature stand to
