Just as the Romans and Etruscans cut up the heavens with rigid mathematical lines and confined a god within each of the spaces thereby delimited, as within a templum, so every people has a similarly mathematically divided conceptual heaven above themselves and henceforth thinks that truth demands that each conceptual god be sought only within his own sphere. Here one may certainly admire man as a mighty genius of construction, who succeeds in piling an infinitely complicated dome of concepts upon an unstable foundation, and, as it were, on running water. Of course, in order to be supported by such a foundation, his construction must be like one constructed of spiders' webs: delicate enough to be carried along by the waves, strong enough not to be blown apart by every wind. As a genius of construction man raises himself far above the bee in the following way: whereas the bee builds with wax that he gathers from nature, man builds with the far more delicate conceptual material which he first has to manufacture from himself. In this he is greatly to be admired, but not on account of his drive for truth or for pure knowledge of things. When someone hides something behind a bush and looks for it again in the same place and finds it there as well, there is not much to praise in such seeking and finding. Yet this is how matters stand regarding seeking and finding "truth" within the realm of reason. If I make up the definition of a mammal, and then, after inspecting a camel, declare "look, a mammal" I have indeed brought a truth to light in this way, but it is a truth of limited value. That is to say, it is a thoroughly anthropomorphic truth which contains not a single point which would be "true in itself" or really and universally valid apart from man. At bottom, what the investigator of such truths is seeking is only the metamorphosis of the world into man. He strives to understand the world as something analogous to man, and at best he achieves by his struggles the feeling of assimilation. Similar to the way in which astrologers considered the stars to be in man 's service and connected with his happiness and sorrow, such an investigator considers the entire universe in connection with man: the entire universe as the infinitely fractured echo of one original sound-man; the entire universe as the infinitely multiplied copy of one original picture-man. His method is to treat man as the measure of all things, but in doing so he again proceeds from the error of believing that he has these things [which he intends to measure] immediately before him as mere objects. He forgets that the original perceptual metaphors are metaphors and takes them to be the things themselves.
