That work thinks this thinker's one and only thought: the thought of the eternal recurrence of the same. Every thinker thinks one only thought. Here, too, thinking differs essentially from science. The researcher needs constantly new discoveries and inspirations, else science will bog down and fall into error. The thinker needs one thought only.

But speak of the Same in the manner that befits it only if we always say the same about it, in such a way that we ourselves are claimed by the Self-Same. The limitlessness of the Same is the sharpest limit set to thinking. The thinker Nietzsche hints at this hidden fittingness of thought by giving his Thus Spoke Zarathustra a subtitle which runs: A Book for Every one No One. "For Everyone"—that does not for everybody as just anybody; "For Everyone" means for each man as man, for each each time his essential nature becomes for an object worthy of his thought. "And No One"—that means: for none among these men prevailing everywhere who merely intoxicate themselves with isolated fragments and passages from the book and then blindly stumble about in its language, instead of getting underway on its way of thinking, and thus becoming first of all questionable to themselves. Thus Spoke Zarathustra: A Book for Everyone and No One. In what an unearthly fashion this subtitle has come true in the seventy years since the book first appeared—only in the exactly opposite sense. It has become a book for everyman, and not one thinker has appeared who could stand up to this book's basic thought, and to its darkness. In this book, its fourth and final part, Nietzsche wrote the words: wasteland grows . . ."
