Albertus Magnus, O.P. (1193/1206 - November 15, 1280), also known as Saint Albert the Great and Albert of Cologne, was a Dominican friar and bishop who achieved fame for his comprehensive knowledge of and advocacy for the peaceful coexistence of science and religion. He is considered to be the greatest German philosopher and theologian of the Middle Ages. He was the first among medieval scholars to apply Aristotle's philosophy to Christian thought. Catholicism honors him as a Doctor of the Church, one of only 33 persons with that honor.
Albertus was educated principally at Padua, where he received instruction in Aristotle's writings. A late account by Rudolph de Novamagia refers to Albertus' encounter with the Blessed Virgin Mary, who convinced him to enter Holy Orders. In 1223 (or 1221) he became a member of the Dominican Order, against the wishes of his family, and studied theology at Bologna and elsewhere. Selected to fill the position of lecturer at Cologne, Germany, where the Dominicans had a house, he taught for several years there, at Regensburg, Freiburg, Strasbourg and Hildesheim. In 1245 he went to Paris, received his doctorate and taught for some time as a master of theology with great success. During this time Thomas Aquinas began to study under Albertus.
In 1254 Albertus was made provincial of the Dominican Order, and fulfilled the arduous duties of the office with great care and efficiency. During his tenure he publicly defended the Dominicans against attacks by the secular and regular faculty of the University of Paris, commented on St John, and answered what he perceived as errors of the Arabian philosopher Averroes.
In 1260 Pope Alexander IV made him Bishop of Regensburg, which office he resigned after three years. During the exercise of his duties he enhanced his reputation for humility by refusing to ride a horse--in accord with the dictates of the Dominican order--instead walking back and forth across his huge diocese. This earned him the affectionate sobriquet, "boots the bishop," from his parishioners. After his stint as bishop, he spent the remainder of his life partly in retirement in the various houses of his order, yet often preaching throughout southern Germany. In 1270 he preached the eighth Crusade in Austria. Among the last of his labours was the defence of the orthodoxy of his former pupil, Thomas Aquinas, whose death in 1274 grieved Albertus. After suffering a collapse of health in 1278, he died on November 15, 1280, in Cologne, Germany. His tomb is in the crypt of the Dominican church of St. Andreas in Cologne, and his relics at the Cologne Cathedral.
Albertus is frequently mentioned by Dante, who made his doctrine of free will the basis of his ethical system. In his Divine Comedy, Dante places Albertus with his pupil Thomas Aquinas among the great lovers of wisdom (Spiriti Sapienti) in the Heaven of the Sun. Albertus is also mentioned, along with Agrippa and Paracelsus, in Mary Shelly's Frankenstein, where his writings serve as an influence to a young Victor Frankenstein.
Albertus was beatified in 1622. He was canonized and officially named a Doctor of the Church in 1931 by Pope Pius XI. His feast day is celebrated on November 15.
Albertus' writings collected in 1899 went to thirty-eight volumes. These displayed his prolific habits and literally encyclopedic knowledge of topics such as logic, theology, botany, geography, astronomy, astrology, mineralogy, chemistry, zoology, physiology, phrenology and others; all of which were the result of logic and observation. He was perhaps the most widely read author of his time. He digested, interpreted and systematized the whole of Aristotle's works, gleaned from the Latin translations and notes of the Arabian commentators, in accordance with Church doctrine. He came to be so associated with Aristotle that he was sometimes referred to as "Aristotle's Ape". Most modern knowledge of Aristotle was preserved and presented by Albertus.
Albertus' activity, however, was more philosophical than theological (see Scholasticism). The philosophical works, occupying the first six and the last of the twenty-one volumes, are generally divided according to the Aristotelian scheme of the sciences, and consist of interpretations and condensations of Aristotle's relative works, with supplementary discussions upon contemporary topics, and occasional divergences from the opinions of the master.
His principal theological works are a commentary in three volumes on the Books of the Sentences of Peter Lombard (Magister Sententiarum), and the Summa Theologiae in two volumes. The latter is in substance a more didactic repetition of the former.
Albertus's knowledge of physical science was considerable and for the age remarkably accurate. His industry in every department was great, and though we find in his system many gaps which are characteristic of scholastic philosophy, his protracted study of Aristotle gave him a great power of systematic thought and exposition. His scholarly legacy justifies his contemporaries' bestowing upon him the honourable surname Doctor Universalis. It must, however, be admitted that much of his knowledge was ill digested; it even appears that he regarded Plato and Speusippus as Stoics.
In the centuries since his death, many stories arose about Albertus as an alchemist and magician. On the subject of alchemy and chemistry, he wrote treaties on Alchemy; Metals and Materials; the Secrets of Chemistry; the Origin of Metals; the Origins of Compounds, and a Concordance which is a collection of Observations on the philosopher's stone; and other alchemy-chemistry topics, collected under the name of Theatrum Chemicum. He is credited with the discovery of the element arsenic. He did believe that stones had occult properties, as he related in his work De mineralibus. However, there is scant evidence that he personally performed alchemical experiments. Much of the modern confusion results from the fact that later works, particularly the alchemical work known as the Secreta Alberti or the Experimenta Alberti, were falsely attributed to Albertus by their authors in order to increase the prestige of the text through association.
According to legend, Albertus Magnus is said to have discovered the philosopher's stone and passed it to his pupil Thomas Aquinas, shortly before his death. Magnus does not confirm he discovered the stone in his writings, but he did record that he witnessed the creation of gold by "transmutation. Given that Thomas Aquinas died six years before Albertus Magnus' death, this legend as stated is unlikely.
However, it is true that Albertus was deeply interested in astrology, as has been articulated by scholars such as Paola Zambelli. While today we would view this as evidence of superstition, in the high Middle Ages--and well into the early modern period--few intellectuals, if any, questioned the basic assumptions of astrology: humans live within a web of celestial influences that affect our bodies, and thereby motivate us to behave in certain ways. Within this worldview, it was logical to believe that astrology could be used to predict the probable future of a human being. Albertus made this a central component of his philosophical system, arguing that an understanding of the celestial influences affecting us could help us to live our lives more in accord with Christian precepts. The most comprehensive statement of his astrological beliefs is to be found in a work he authored around 1260, now known as the Speculum astronomiae. However, details of these beliefs can be found in almost everything he wrote, from his early Summa de bono to his last work, the Summa theologiae.
