Now when, in this mental laboratory, which served less for analytic chemistry than for synthetic science, he ascended from the turmaline which attracts grains of ashes to the sun which attracts worlds, and even to the unknown sun toward which solar systems fly; or when the anatomical charts were to him the perspective sketch of a divine architecture, and the dissecting-knife became the gnomon of his favorite truth: that, in order to believe in a God, there was need of nothing more than two men, of whom the one might be dead, too, that the living one could study him, and turn over his leaves[89]; or when Poetry, as a second nature, as a second music, wafted him upward softly on her invisible ether, and he chose undecidedly between the pen and the keys, when he wanted to communicate aloft; ... when, in short, in his heavenly sphere, supported on a human cervical-vertebra, the nebula of ideas gradually resolved itself into bright and dark parts, and beneath an unseen sun filled itself more and more with ether,--when one cloud became conductor to another,--when at last the gleaming mass of cloud came together,--then did the inner heaven (as the outer one often does), by eleven o'clock in the forenoon, grow from all the flashes into one sun, from all the drops into one flood, and the whole heaven of the upper faculties came down to the earth of the lower ones, and ... some blue patches of the second world were for a flying moment open. We cannot delineate our inner states more philosophically and clearly than by metaphors, i. e. by the colors of related states. The narrow defamers of metaphors, who, instead of the brush, would rather give us the black-lead, ascribe to the _coloring_ the unrecognizableness of the _drawing_; but they ought to charge it merely on their non-acquaintance with the original subject. Verily, nonsense plays hide-and-seek more easily in the roomy, abstract, artificial words of the philosophers--since words, like Chinese shadows, increase with their circumference at once the obscurity and the emptiness of their contents--than in the narrow green hulls of the poets. From the Stoa and the Portico of thought one must have an outlook into the Epicurean gardens of poetry.
