" All his life long he had been amazed at the way ideas have of agglomerating, divorced from feeling, like crystals in strange, meaningless formations; and of growing like tumors, devouring the flesh that conceives them; or of assuming certain human lineaments, but in monstrous wise, like those inert masses to which some women give birth, and which are, after all, only the incoherent dreams of matter. He found that a goodly number of the mind's productions are no more than such deformed mooncalves. Other conceptions, less impure and more precise, forged as if by a master workman, make for illusion when viewed from afar; though commanding our admiration for their parallels and their angles, like intricate iron grills, they are nevertheless only bars behind which the understanding imprisons itself, abstract fetters already eaten into by the rust of false premises.

" Another, more fluid metaphor for the world of thought gradually suggested itself to him, derived from his former voyages at sea. A philosopher who was trying to consider human understanding in all its aspects would behold beneath him a mass molded in calculable curves, streaked by currents which could be charted, and deeply furrowed by the pressure of winds and the heavy, inert weight of water. It seemed to him that the shapes which the mind assumes are like those great forms, born of undifferentiated water, which assail or replace each other on the surface of the deep; each concept collapses, eventually, to merge with its very opposite, like two waves breaking against each other only to subside into the same single line of white foam.

" His bowels, far greater alchemist than he had ever been, regularly performed the transmutation of corpses, those of beasts and of plants, into living matter, separating the useful from the dross without help from him. Ignis inferioris Naturae: those spirals of brown mud, precisely coiled and still steaming from the decocting process which they have undergone in their mold, this ammoniac and nitric fluid passed into a clay pot, were the visible and fetid proof of work completed in laboratories where we do not intervene. It seemed to Zeno that the disgust of fastidious persons at this refuse, and the obscene laughter of the ignorant, were due less to the fact that these objects offend our senses than to our horror in the presence of the mysterious and ineluctable routines of our bodies.
