Citações Alberto Magno
„Só a experiência nos pode certificar nessas coisas“
do latim: “Experimentum solum certificat in talibus”, in: De vegetabilibus et plantis, VI, tr. ii, i.; citado por João Cesar das Neves; «www.raptussancti.net - Um encontro com S. Tomás de Aquino» (Editorial Verbo, 2006) http://www.raptussancti.net/bio_salberto.html
„a finalidade das ciências naturais não é apenas aceitar as afirmações de outros, mas investigar as causas que existem na natureza“
De Mineralium, lib. II, tr. ii, i; citado por João César das Neves; «www.raptussancti.net - Um encontro com S. Tomás de Aquino» (Editorial Verbo, 2006) http://www.raptussancti.net/bio_salberto.html
„The metals are all essentially identical; they differ only in form. Now, the form brings out accidental causes, which the experimenter must try to discover and remove, as far as possible. Accidental causes impede the regular union of sulphur and mercury; for every metal is a combination of sulphur and mercury. A diseased womb may give birth to a weakly, leprous child, although the seed was good; the same is true of the metals which are generated in the bowels of the earth, which is a womb for them; any cause whatever, or local trouble, may produce an imperfect metal. When pure sulphur comes in contact with pure mercury, after more or less time, and by the permanent action of nature, gold is produced.“
As quoted by Francis Preston Venable, A Short History of Chemistry (1894) p. 28. https://books.google.com/books?id=fN9YAAAAYAAJ&pg=PA28

„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.“
