But shall I make this garland to be put upon a wrong head? Would anybody believe me, if I should verify this upon the knowledge that is now in use? Are we the richer by one poor invention, by reason of all the learning that hath been these many hundred years? The industry of artificers maketh some small improvement of things invented; and chance sometimes in experimenting maketh us to stumble upon somewhat which is new; but all the disputation of the learned never brought to light one effect of nature before unknown. When things are known and found out, then they can descant upon them, they can knit them into certain causes, they can reduce them to their principles. If any instance of experience stand against them, they can range it in order by some distinctions. But all this is but a web of the wit, it can work nothing. I do not doubt but that common notions, which we call reason, and the knitting of them together, which we call logic, are the art of reason and studies. But they rather cast obscurity than gain light to the contemplation of nature. All the philosophy of nature which is now received, is either the philosophy of the Grecians, or that other of the Alchemists. That of the Grecians hath the foundations in words, in ostentation, in confutation, in sects, in schools, in disputations. The Grecians were (as one of themselves saith), "you Grecians, ever children." They knew little antiquity; they knew (except fables) not much above five hundred years before themselves; they knew but a small portion of the world. That of the Alchemists hath the foundation in imposture, in auricular traditions and obscurity; it was catching hold of religion, but the principle of it is, "Populus vult decipi." So that I know no great difference between these great philosophies, but that the one is a loud-crying folly, and the other is a whispering folly. The one is gathered out of a few vulgar observations, and the other out of a few experiments of a furnace. The one never faileth to multiply words, and the other ever faileth to multiply gold. Who would not smile at Aristotle, when he admireth the eternity and invariableness of the heavens, as there were not the like in the bowels of the earth? Those be the confines and borders of these two kingdoms, where the continual alteration and incursion are. The superficies and upper parts of the earth are full of varieties. The superficies and lower part of the heavens (which we call the middle region of the air) is full of variety. There is much spirit in the one part that cannot be brought into mass. There is much massy body in the other place that cannot be refined to spirit. The common air is as the waste ground between the borders. Who would not smile at the astronomers? I mean not these new carmen which drive the earth about, but the ancient astronomers, which feign the moon to be the swiftest of all planets in motion, and the rest in order, the
