QUOTE : 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.
