Extraordinary Popular Delusions And The Madness Of Crowds
Vol. III - Philosophical Delusions 1
Chapter 29 - Roger Bacon
The powerful delusion of alchymy seized upon a mind still greater than that of Raymond Lulli. Roger Bacon firmly believed in the philosopher's stone, and spent much of his time in search of it. His example helped to render all the learned men of the time more convinced of its practicability, and more eager in the pursuit. He was born at Ilchester, in the county of Somerset, in the year 1214. He studied for some time in the University of Oxford, and afterwards in that of Paris, in which he received the degree of doctor of divinity. Returning to England in 1240, he became a monk of the order of St. Francis. He was by far the most learned man of his age; and his acquirements were so much above the comprehension of his contemporaries, that they could only account for them by supposing that he was indebted for them to the devil. Voltaire has not inaptly designated him "De l'or encroute de toutes les ordures de son siecle;" but the crust of superstition that enveloped his powerful mind, though it may have dimmed, could not obscure the brightness of his genius. To him, and apparently to him only, among all the inquiring spirits of the time, were known the properties of the concave and convex lens. He also invented the magic-lantern; that pretty plaything of modern days, which acquired for him a reputation that embittered his life. In a history of alchymy, the name of this great man cannot be omitted, although, unlike many others of whom we shall have occasion to speak, he only made it secondary to other pursuits. The love of universal knowledge that filled his mind, would not allow him to neglect one branch of science, of which neither he nor the world could yet see the absurdity. He made ample amends for his time lost in this pursuit by his knowledge in physics and his acquaintance with astronomy. The telescope, burning-glasses, and gunpowder, are discoveries which may well carry his fame to the remotest time, and make the world blind to the one spot of folly -- the diagnosis of the age in which he lived, and the circumstances by which he was surrounded. His treatise on the "Admirable Power of Art and Nature in the Production of the Philosopher's Stone" was translated into French by Girard de Tormes, and published at Lyons in 1557. His "Mirror of Alchymy" was also published in French in the same year, and in Paris in 1612, with some additions from the works of Raymond Lulli. A complete list of all the published treatises upon the subject may be seen in Lenglet du Fresnoy.
