My thoughts on the descent of our moral prejudices – for that is what this polemic is about – were first set out in a sketchy and provisional way in the collection of aphorisms entitled Human, All Too Human. A Book for Free Spirits, which I began to write in Sorrento during a winter that enabled me to pause, like a wanderer pauses, to take in the vast and dangerous land through which my mind had hitherto travelled. This was in the winter of 1876–7; the thoughts themselves go back further. They were mainly the same thoughts which I shall be taking up again in the present essays – let us hope that the long interval has done them good, that they have become riper, brighter, stronger and more perfect! The fact that I still stick to them today, and that they themselves in the meantime have stuck together increasingly firmly, even growing into one another and growing into one, makes me all the more blithely confident that from the first, they did not arise in me individually, randomly or sporadically but as stemming from a single root, from a fundamental will to knowledge deep inside me which took control, speaking more and more clearly and making ever clearer demands. And this is the only thing proper for a philosopher. We have no right to stand out individually: we must not either make mistakes or hit on the truth individually. Instead, our thoughts, values, every ‘yes’, ‘no’, ‘if ’ and ‘but’ grow from us with the same inevitability as fruits borne on the tree – all related and referring to one another and a testimonial to one will, one health, one earth, one sun. – Do you like the taste of our fruit? – But of what concern is that to the trees? And of what concern is it to us philosophers? . . .
You desire to LIVE "according to Nature"? Oh, you noble Stoics, what fraud of words! Imagine to yourselves a being like Nature, boundlessly extravagant, boundlessly indifferent, without purpose or consideration, without pity or justice, at once fruitful and barren and uncertain: imagine to yourselves INDIFFERENCE as a power—how COULD you live in accordance with such indifference? To live—is not that just endeavouring to be otherwise than this Nature? Is not living valuing, preferring, being unjust, being limited, endeavouring to be different? And granted that your imperative, "living according to Nature," means actually the same as "living according to life"—how could you do DIFFERENTLY? Why should you make a principle out of what you yourselves are, and must be? In reality, however, it is quite otherwise with you: while you pretend to read with rapture the canon of your law in Nature, you want something quite the contrary, you extraordinary stage-players and self-deluders! In your pride you wish to dictate your morals and ideals to Nature, to Nature herself, and to incorporate them therein; you insist that it shall be Nature "according to the Stoa," and would like everything to be made after your own image, as a vast, eternal glorification and generalism of Stoicism! With all your love for truth, you have forced yourselves so long, so persistently, and with such hypnotic rigidity to see Nature FALSELY, that is to say, Stoically, that you are no longer able to see it otherwise—and to crown all, some unfathomable superciliousness gives you the Bedlamite hope that BECAUSE you are able to tyrannize over yourselves—Stoicism is self-tyranny—Nature will also allow herself to be tyrannized over: is not the Stoic a PART of Nature?... But this is an old and everlasting story: what happened in old times with the Stoics still happens today, as soon as ever a philosophy begins to believe in itself. It always creates the world in its own image; it cannot do otherwise; philosophy is this tyrannical impulse itself, the most spiritual Will to Power, the will to "creation of the world," the will to the causa prima.
