Albertus Magnus

“"Albertus Magnus, Saint" by William A. Wallace (1970) in Gillispie, Charles. Dictionary of Scientific Biography 1. New York: Scribner & American Council of Learned Societies. pp. 99–103.”

“In speaking of Thomas Aquinas, who, it is true, had not attained at the time when Roger Bacon wrote to the commanding position of authority which was afterwards accorded to him in the schools, he couples him with Albertus Magnus, and says that they both became teachers before they had been adequately taught, and lectured on a philosophy and a theology which they had imperfectly learned.”

“Of Albertus Magnus, the Doctor Universalis of the Dominicans, Roger Bacon writes that what is useful in his works might be summed up in a treatise twenty times as short as they are.”

“Do there exist many worlds, or is there but a single world? This is one of the most noble and exalted questions in the study of Nature.”

“Natural science does not consist in ratifying what others have said, but in seeking the causes of phenomena.”

“This dumb ox will fill the world with his bellowing.”

“If the excrement of an elephant should be smeared on skin in which lice appear and left until it dries upon the skin, the lice will not remain on it but will depart immediately. If the fat of an elephant is smeared with it, it is said to cure the pain of one who suffers a headache; it is even said that if an ounce of elephant bone is drunk with ten ounces of wild mountain mint from something which a leper first touched, it does the most for a headache.”
