Albertus Magnus

Albertus Magnus , also known as Saint Albert the Great, Albert of Swabia, 'Albert von Bollstadt, or Albert of Cologne', was a German Dominican friar, philosopher, scientist, and bishop. He is considered one of the greatest medieval philosophers and thinkers.
Canonized in 1931, he was known during his lifetime as Doctor universalis and Doctor expertus; late in his life the sobriquet Magnus was appended to his name. Scholars such as James A. Weisheipl and Joachim R. Söder have referred to him as the greatest German philosopher and theologian of the Middle Ages. The Catholic Church distinguishes him as one of the Doctors of the Church.

Biography

It seems likely that Albertus Magnus was born sometime before 1200, given well-attested evidence that he was aged over 80 on his death in 1280. Two later sources say that Albert was about 87 on his death, which has led 1193 to be commonly given as the date of Albert's birth, but this information does not have enough evidence to be confirmed. Albert was probably born in Lauingen, since he called himself 'Albert of Lauingen', but this might simply be a family name. Most probably his family was of ministerial class; his familial connection with the Bollstädt noble family is almost certainly mere conjecture by 15th-century hagiographers.
Albert was probably educated principally at the University of 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, he became a member of the Dominican Order, 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, as well as in Regensburg, Freiburg, Strasbourg, and Hildesheim. During his first tenure as lecturer at Cologne, Albert wrote his Summa de bono after having a discussion with Philip the Chancellor concerning the transcendental properties of being. In 1245, Albert became master of theology under Guerric of Saint-Quentin, the first German Dominican to achieve this distinction. Following this turn of events, Albert was able to teach theology at the University of Paris as a full-time professor, holding the seat of the Chair of Theology at the College of St. James. During this time Thomas Aquinas began to study under Albertus.
Albert was the first to comment on virtually all of the writings of Aristotle, thus making them accessible to wider academic debate. The study of Aristotle brought him to study and comment on the teachings of Muslim academics, notably Avicenna and Averroes, and this would bring him into the heart of academic debate.
In 1254, Albert was made provincial of the Dominican Order and fulfilled the duties of the office with great care and efficiency. During his tenure, he publicly defended the Dominicans against attacks by the secular faculty of the University of Paris, commented on John the Evangelist, and answered what he perceived as errors of the Islamic philosopher Averroes.
In 1259, Albert took part in the General Chapter of the Dominicans at Valenciennes together with Thomas Aquinas, masters Bonushomo Britto, Florentius, and Peter, establishing a ratio studiorum or program of studies for the Dominicans that featured the study of philosophy as an innovation for those not sufficiently trained to study theology. This innovation initiated the tradition of Dominican scholastic philosophy put into practice, for example, in 1265 at the Order's studium provinciale at the convent of Santa Sabina in Rome, out of which would develop the Pontifical University of Saint Thomas Aquinas, the "Angelicum".

In 1260, Pope Alexander IV made him bishop of Regensburg, an office from which 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 Order, instead traversing his huge diocese on foot. In 1263, Pope Urban IV relieved him of the duties of bishop and asked him to preach the Eighth Crusade in German-speaking countries. After this, he was especially known for acting as a mediator between conflicting parties. In Cologne, he is known not only for being the founder of one of Germany's oldest universities there, but also for "the big verdict" of 1258, which brought an end to the conflict between the citizens of Cologne and the archbishop. Among the last of his labors was the defense of the orthodoxy of his former pupil, Thomas Aquinas, whose death in 1274 grieved Albert.
Albert was a scientist, philosopher, astrologer, theologian, spiritual writer, ecumenist, and diplomat. Under the auspices of Humbert of Romans, Albert molded the curriculum of studies for all Dominican students, introduced Aristotle to the classroom and probed the work of Neoplatonists, such as Plotinus. Indeed, it was the thirty years of work done by Aquinas and himself that allowed for the inclusion of Aristotelian study in the curriculum of Dominican schools.
After suffering declining health in 1278, he died on 15 November 1280 in the Dominican convent in Cologne, Germany. His relics are located in a Roman sarcophagus in the crypt of the Dominican St. Andrew's Church in Cologne. His body was claimed to be incorrupt during an exhumation three years after his death. However, a later exhumation in 1483 found that only a skeleton remained. The Saint Stephen's Church in Nijmegen, the Netherlands, also houses a relic.
Albert was beatified in 1622. He was canonized and proclaimed a Doctor of the Church on 16 December 1931 by Pope Pius XI and the patron saint of natural scientists in 1941. St. Albert's feast day is November 15.
Among the first biographical sources, there were Heinrich von Herford and Luis of Valladolid_es and, in modern times, the study by James A. Weisheipl, who reconstructs the life and works of Albertus Magnus taking into account all previous biographies and places his date of birth around 1200.

Writings

Albert's writings collected in 1899 went to thirty-eight volumes. These displayed his prolific habits and encyclopedic knowledge of topics such as logic, theology, botany, geography, astronomy, astrology, mineralogy, alchemy, zoology, physiology, phrenology, justice, law, friendship, and love. 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. Most modern knowledge of Aristotle was preserved and presented by Albert.
His principal theological works are a commentary in three volumes on the Books of the Sentences of Peter Lombard, and the Summa Theologiae in two volumes. The latter is in substance a more didactic repetition of the former.
Albert's activity, however, was more philosophical than theological. The philosophical works, occupying the first six and the last of the 21 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. Albert believed that Aristotle's approach to natural philosophy did not pose any obstacle to the development of a Christian philosophical view of the natural order.
Albert's knowledge of natural science was considerable and for the age remarkably accurate. His industry in every department was great: not only did he produce commentaries and paraphrases of the entire Aristotelian corpus, including his scientific works, but Albert also added to and improved upon them. His books on topics like botany, zoology, and minerals included information from ancient sources, but also results of his own empirical investigations. These investigations pushed several of the special sciences forward, beyond the reliance on classical texts. In the case of embryology, for example, it has been claimed that little of value was written after Aristotle until Albert, who managed to identify organs within eggs. Furthermore, Albert also effectively invented entire special sciences, where Aristotle has not covered a topic. For example, prior to Albert, there was no systematic study of minerals. For the breadth of these achievements, he was bestowed the name Doctor Universalis.
Much of Albert's empirical contributions to the natural sciences have been superseded, but his general approach to science may be surprisingly modern. For example, in De Mineralibus Albert claims, "For it is of natural science not simply to accept what we are told but to inquire into the causes of natural things."

Alchemy

In the centuries since his death, many stories arose about Albert as an alchemist and magician. "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 to increase the prestige of the text through association." On the subject of alchemy and chemistry, many treatises relating to alchemy have been attributed to him, though in his authentic writings he had little to say on the subject, and then mostly through commentary on Aristotle. For example, in his commentary, De mineralibus, he refers to the power of stones, but does not elaborate on what these powers might be. A wide range of Pseudo-Albertine works dealing with alchemy exist, though, showing the belief developed in the generations following Albert's death that he had mastered alchemy, one of the fundamental sciences of the Middle Ages. These include 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 and experimented with photosensitive chemicals, including silver nitrate. 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.
According to legend, Albert is said to have discovered the philosopher's stone and passed it on to his pupil Thomas Aquinas, shortly before his death. Albert 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 Albert's death, this legend as stated is unlikely.
