Extractions: On Experimental Science, 1268 Having laid down the main points of the wisdom of the Latins as regards language, mathematics and optics, I wish now to review the principles of wisdom from the point of view of experimental science, because without experiment it is impossible to know anything thoroughly. There are two ways of acquiring knowledge, one through reason, the other by experiment. Argument reaches a conclusion and compels us to admit it, but it neither makes us certain nor so annihilates doubt that the mind rests calm in the intuition of truth, unless it finds this certitude by way of experience. Thus many have arguments toward attainable facts, but because they have not experienced them, they overlook them and neither avoid a harmful nor follow a beneficial course. Even if a man that has never seen fire, proves by good reasoning that fire burns, and devours and destroys things, nevertheless the mind of one hearing his arguments would never be convinced, nor would he avoid fire until he puts his hand or some combustible thing into it in order to prove by experiment what the argument taught. But after the fact of combustion is experienced, the mind is satisfied and lies calm in the certainty of truth. Hence argument is not enough, but experience is.

He set out his own new model for a system of philosophical studies that would incorporate language studies and science studies then unavailable at the Universities. He succeeded in setting out a model of an experimental science on the basis of his study of Optics ( Perspectiva ). He does this in a new context: the application of linguistic and scientific knowledge for a better understanding of Theology and in the service of the Res publica Christiana Secretum secretorum , a Latin translation of the Arabic text on the education of the Prince, the . He believed it to be a work by Aristotle for Alexander the Great. He died at Oxford ca. 1292. Modern understanding of the Philosophy of Roger Bacon is largely conditioned by two distinct traditions of interpretation from the nineteenth century. The first is the study of the physical, metaphysical, and related works of Bacon. Discovered in 1848 by Victor Cousin in Amiens MS 406, these works were edited by Robert Steele and Ferdinand Delorme (OHI, 1905-1940) .

Soon after his return to England in about 1251, he entered the religious order of the Franciscans and settled at Oxford. He carried on active studies and did experimental research, mainly in alchemy, optics, and astronomy. Bacon was critical of the methods of learning of the times, and in the late 1260s, at the request of Pope Clement IV, he wrote his

Extractions: Send it to a friend! Bacon was an English Franciscan friar, philosopher, scientist and scholar of the 13th century. Roger Bacon's date and place of birth are unknown but he is thought to have come from a relatively wealthy family. He studied and later taught at Oxford University and also taught the University of Paris. Bacon has a wide range of interests. He investigated optics and the refraction of light through lenses, leading to the development of spectacles. He sought reform of the calendar, and was interested in astronomy. In 1266, at the request of Pope Clement IV, he collected many of his observations in his 'Opus Maius', an encyclopaedia of all science. Bacon had a reputation as unconventional scholar, pursuing learning in alchemy and magic - interests which earned him the soubriquet 'Doctor Mirabilis'. This led to his rejection from the Franciscans and eventual imprisonment. He died in Oxford not long after his release.
ROGER BACON'S PLACE IN THE HISTORY OF ALCHEMY
Footnoted journal article by Edmund Brehm, discussing bacon s contributions to alchemy. Features a diagram showing how alchemy fit into bacon s world
http://www.levity.com/alchemy/rbacon.html

Extractions: AMBIX Vol. 23, Part I, March 1976 A LCHEMY , throughout its history, has shown a dual nature. On the one hand, it has involved the use of chemical substances and so is claimed by the history of science as the precursor of modern chemistry. Yet at the same time, alchemy has, throughout its history, also been associated with the esoteric, spiritual beliefs of Hermeticism and thus is a proper subject for the historian of religious thought. The chemical approach is easily understood. As the distinguished historian of alchemy, the late F. Sherwood Taylor, concluded: "The hopeless pursuit of the practical transmutation of metals was responsible for almost the whole of the development of chemical technique before the seventeenth century, and further led to the discovery of many important materials. This is the commonly recognized contribution of alchemy." Mircea Eliade and others, on the other hand, have emphasized the soteriological function of alchemy as working toward the perfection and liberation of the human soul or spirit, a process symbolized in the perfection of metals into gold and of the human body to a state of optimum health and even immortality. Such an approach is complemented by the psychological studies of C. G. Jung, which correlate alchemical symbolism with the development of the psycho-religious life of the individual. Eliade has conclusively demonstrated the religious nature of alchemy in Eastern cultures, and Jung has discussed the psychological basis of Western alchemy during its later period (the sixteenth and seventeenth centuries). But European alchemy during the Middle Ages, especially from a religious point of view, has received little attention.

http://www.strangescience.net/rbacon.htm

Extractions: About a century after Roger Bacon's death, a physician named Peter of Trou claimed Bacon could conjure a bridge out of thin air, or use his magic mirror to see any part of the world. He was even said to make a brazen head that exactly matched human anatomy, and to work with Satan to give it a voice. Bacon eventually acquired the reputation of a charlatan, as well as a dabbler in black magic. Besides contradicting each other, these characterizations of Bacon could not have been more ironic; during his lifetime, he never hid his disdain for people who claimed to have magical powers. Because he studied in England and not France, Bacon could read the writings of Aristotle. When France eventually allowed its students to do the same, scholars with Bacon's knowledge were in demand, so he traveled to the University of Paris in the 1240s to teach. Around this time, he read Secretum Secretorum , a book covering politics, medicine and natural philosophy. Although attributed to Aristotle, the work's origins were obscure, and it reached medieval Europe through Muslim scholars. The combination of Greek (hence Pagan) and Islamic science concerned many Europeans, but it fascinated Bacon. His fondness for this book was just one instance where his interests aroused suspicion among religious authorities, and the opinions of religious authorities mattered in Bacon's life because he became a Franciscan friar. Roger Bacon suddenly found himself backed by the most powerful man in Europe: Pope Clement IV. In 1267, more or less on the orders of Clement IV, Bacon produced

http://www.roma1.infn.it/rog/group/frasca/b/bacon.html

Extractions: from Global Encyclopedia Roger Bacon (1214-1294) was an English philosopher during the Middle Ages. Bacon is also considered a scientist because he insisted on observing things for himself instead of depending on what people had written. Most of his experiments involved optics, the study of light. His work encouraged people to try experiments of their own, and this helped bring about the Rennaisance. Bacon's family appears to have been well off, but in the stormy reign of Henry III. their property was despoiled and several members of the family were driven into exile. Roger completed his studies at Oxford, though not, as current traditions assert, at Merton or at Brasenose, neither of which had been founded. His abilities were speedily recognized by his contemporaries, and he enjoyed the friendship of such eminent men as Adam de Marisco and Robert Grosseteste, bishop of Lincoln. Very little is known of Bacon's life at Oxford; it is said he took clerical orders in 1233, and this is not improbable. In the following year, or perhaps later, he crossed over to France and studied at the university of Paris, then the center of intellectual life in Europe. The two great monastic orders, Franciscans and Dominicans, were in the vigor of youth, and had already begun to take the lead in theological discussion. Alexander of Hales was the oracle of the Franciscans, while the rival order rejoiced in Albertus Magnus and Thomas Aquinas. The scientific training which Bacon had received, mainly from the study of the Arab writers, showed him the manifold defects in the systems reared by these doctors. Aristotle was known but in part, and that part was rendered well-nigh unintelligible through the vileness of the translations; yet not one of those professors would learn Greek. The Scriptures read, if at all, in the erroneous versions were being deserted for the Sentences of Peter Lombard.

Extractions: R OGER B ACON WHEREVER thought has struggled to be free, there the great Theosophical Movement is to be discerned. The twelfth century is interesting from this point of view, as it marked the beginning of the struggle for intellectual freedom in Christian Europe. Up to this time the Church had been the only educational institution in Christendom, and no one, unless he were a member of the clergy or had studied in some monastical institution, could either read or write. But in the twelfth century small groups of students began to gather in France, determined to gain an education themselves and to pass on their knowledge to others. In 1100 a young man named Peter Abelard came in contact with some of these students. He prepared himself to teach and encouraged others to do the same. As the result of his efforts, the teachers of Paris formed a guild or union, known as a Universitas, and from this original impulse sprang the first Universities in Christian Europe. At the same time another group of people banded themselves together for altruistic service, and in 1118 the Order of the Knights Templar was founded by the two Knights Hugh de Payens and Geoffrey de St. Omer. The purpose of this Order, on the surface, was to protect pilgrims on their way to the Holy Land. Its secret object, however, was to encourage the new-born struggle for intellectual freedom and to restore the one universal religion in the world. Even Masonic authorities differ as to the forces which lay behind the founding of this Order, although it is agreed that they were in Asia Minor. Lawrie, in his

By Dianna L. Dodson Within the studious atmosphere of their library were gathered the brethren of the Oxford Franciscans. The friars watched as pages were torn from a leather-bound manuscript and nailed to the plans of the library shelves. When the last vellum sheet of the contraband work had been hung to yellow and fade, the friars left the room in silent procession. One or two of the younger novitiates had not known Brother Roger Bacon in his days of fiery verbal assault against mediaeval education and educators. Perhaps they paused to glance at his scrawled handwriting on the desiccated pages and wondered at the nature of his crime. He had died only that month, June 1292. With the post mortem rejection by his home convent began the web of legend that has surrounded Roger Bacon for seven centuries. Popular history has pictured him as a secretive necromancer, while scholars have classed him as everything from a visionary to a cranky old man.

Extractions: Philosopher, surnamed D OCTOR M IRABILIS Some authors connect the fact of imprisonment related in the "Chronica" with the proscription of 219 theses by Stephen Tempier, Bishop of Paris, which took place 7 March, 1277 (Denifle, "Chartularium Universitatis Pariensis", I, 543, 560). Indeed it was not very difficult to find some "suspect innovation" in Bacon's writings, especially with regard to the physical sciences. As F. Mandonnet, O.P., proves, one of his incriminated books or pamphlets was his "Speculum AstronomiÃ¦", written in 1277, hitherto falsely ascribed to Blessed Albert the Great [Opera Omnia, ed. Vives, Paris, X, 629 sq.; cf. Mandonnet, "Roger Bacon et le Speculum AstronomiÃ¦ (1277) in "Revue NÃ©o-Scolastique", XVII, Louvain, 1910, 313-35]. Such and other questions are not yet ripe for judgment; but it is to be hoped that the newly awakened interest in Baconian studies and investigations will clear up more and more what is still obscure in Roger's life.

Extractions: Roger Bacon was an English scholastic philosopher who was also considered a scientist because he insisted on observing things for himself instead of relying on what other people had written. Bacon was born into a wealthy family in 1214 and died in 1294. He was trained in the classics, geometry, arithmetic, music and astronomy and was a student at the University of Paris as a young man where he received the degree of Doctor of Theology. Bacon spent forty years studying and lecturing on the natural sciences at Oxford University in England. For these efforts, he is considered to be the most important cultivator of the natural sciences during the Middle Ages. Bacon's writings included treatises on optics (then called perspective), mathematics, chemistry, arithmetic, astronomy, the tides, and the reformation of the calendar. His skill in the use of optical and mechanical instruments caused him to be regarded by many as a sorcerer. Bacon was acquainted with the properties of mirrors, knew the powers of steam and gunpowder, had a working knowledge in microscopy, and possessed an instrument very much like a modern telescope. He claimed that his telescope could make the most distant object appear near, that it could make stars appear at will, and even further, that it had the power of visualizing future events. Bacon once frightened his students by creating a rainbow by passing light through some glass beads. This demonstration marked one of the earliest attempts to duplicate a natural phenomenon in the laboratory. Bacon believed that the Earth was spherical and that one could sail around it. He estimated the distance to the stars at 130 million miles, and he used a camera that projected an image through a pinhole to observe solar eclipses. His work was so popular that it encouraged others to experiment on their own, and by so doing helped bring about the Renaissance.
