the first perceptual impressions: to build up a pyramidal order with castes and grades, to create a new world of laws, privileges, sub-orders, delimitations, which now stands opposite the other perceptual world of first impressions and assumes the appearance of being the more fixed, general, known, human of the two and therefore the regulating and imperative one. Whereas every metaphor of perception is    individual and without its equal and therefore knows how to escape all attempts to classify it, the great edifice of ideas shows the rigid regularity of a Roman Columbarium and in logic breathes forth the sternness and coolness which we find in mathematics. He who has been breathed upon by this coolness will scarcely believe, that the idea too, bony and hexahedral, and permutable as a die, remains however only as the residuum of a metaphor, and that the illusion of the artistic metamorphosis of a nerve-stimulus into percepts is, if not the mother, then the grandmother of every idea. Now in this game of dice, Truth means to use every die as it is designated, to count its points carefully, to form exact classifications, and never to violate the order of castes and the sequences of rank. Just as the Romans and Etruscans for their benefit cut up the sky by means of strong mathematical lines and banned a god as it were into a templum, into a space limited in this fashion, so every nation has above its head such a sky of ideas divided up mathematically, and it understands the demand for truth to mean that every conceptual god is to be looked for only in his own sphere. One may here well admire man, who succeeded in piling up an infinitely complex dome of ideas on movable foundation and as it were on running water, as a powerful genius of architecture. Of course in order to obtain hold on such a foundation it must be as an edifice piled up out of cobwebs, so fragile, as to be carried away by the waves: so firm, as not to be blown asunder by every wind. In this way man as an architectural genius rises high above the bee; she builds with wax, which she brings together out of nature; he with the much more delicate material of ideas, which he must first manufacture within himself. He is very much to be admired here, but not on account of his impulse for truth, his bent for pure cognition of things. If somebody hides a thing behind a bush, seeks it again and finds it in the selfsame place, then there is not much to boast of, respecting this seeking and finding; thus
