Roger Bacon OFM (/bekn/;[6] Latin: Rogerus or Rogerius Baconus, Baconis, also Frater Rogerus; c.1219/20 c.1292), also known by the scholastic accolade Doctor Mirabilis, was a medieval English philosopher and Franciscan friar who placed considerable emphasis on the study of nature through empiricism. In the early modern era, he was regarded as a wizard and particularly famed for the story of his mechanical or necromantic brazen head. He is sometimes credited (mainly since the 19th century) as one of the earliest European advocates of the modern scientific method. Bacon applied the empirical method of Ibn al-Haytham (Alhazen) to observations in texts attri buted to Aristotle. Bacon discovered the importance of empirical testing when the results he obtained were different than those that would have been predicted by Aristotle.[7][8] (Aristotle had never performed experiments to verify his explanations of his observations of nature.[citation needed])

His linguistic work has been heralded for its early exposition of a universal grammar. However, more recent[when?] re-evaluations emphasise that Bacon was essentially a medieval thinker, with much of his "experimental" knowledge obtained from books in the scholastic tradition.[9] He was, however, partially responsible for a revision of the medieval university curriculum, which saw the addition of optics to the traditional quadrivium.[10]

Bacon's major work, the Opus Majus, was sent to Pope Clement IV in Rome in 1267 upon the pope's request. Although gunpowder was first invented and described in China, Bacon was the first in Europe to record its formula.

32:All sciences are connected; they lend each other material aid as parts of one great whole, each doing its own work, not for itself alone, but for the other parts; as the eye guides the body and the foot sustains it and leads it from place to place. ~ Roger Bacon
33:Few have attained to consummate wisdom in the perfection of philosophy: Solomon attained to it, and Aristotle in relation to his times, and in a later age Avicenna, and in our own days the recently deceased Robert, Bishop of Lincoln, and Adam Marsh. ~ Roger Bacon
34:There are two modes of knowledge: through argument and through experience. Argument brings conclusions and compels us to concede them, but it does not cause certainty nor remove doubts that the mind may rest in truth, unless this is provided by experience. ~ Roger Bacon
35:Neglect of mathematics work injury to all knowledge, since he who is ignorant of it cannot know the other sciences or things of this world. And what is worst, those who are thus ignorant are unable to perceive their own ignorance, and so do not seek a remedy. ~ Roger Bacon
36:All science requires mathematics. The knowledge of mathematical things is almost innate in us. This is the easiest of sciences, a fact which is obvious in that no one's brain rejects it; for laymen and people who are utterly illiterate know how to count and reckon. ~ Roger Bacon
37:It is not necessarily impossible for human beings to fly, but it so happens that God did not give them the knowledge of how to do it. It follows, therefore, that anyone who claims that he can fly must have sought the aid of the devil. To attempt to fly is therefore sinful. ~ Roger Bacon
38:There are four great sciences, without which the other sciences cannot be known nor a knowledge of things secured ... Of these sciences the gate and key is mathematics ... He who is ignorant of this [mathematics] cannot know the other sciences nor the affairs of this world. ~ Roger Bacon
39:[I]f in other sciences we should arrive at certainty without doubt and truth without error, it behooves us to place the foundations of knowledge in mathematics, in so far as disposed through it we are able to reach certainty in other sciences and truth by the exclusion of error. ~ Roger Bacon
40:The thirteenth-century philosopher Roger Bacon claimed that “nobody can obtain to proficiency in the science of mathematics by the method hitherto known unless he devotes to its study thirty or forty years.” Today, the entire body of mathematics known to Bacon is now acquired by your average high school junior. ~ Joshua Foer
41:There are two modes of acquiring knowledge, namely by reasoning and experience. Reasoning draws a conclusion and makes us grant the conclusion, but does not make the conclusion certain, nor does it remove doubt so that the mind may rest on the intuition of truth, unless the mind discovers it by the path of experience. ~ Roger Bacon
42:Roger Bacon, a disciple of the Arabs, also insisted on the primary necessity of Mathematics, without which no other science can be known; yet by Mathematics it is clear that he meant something very different from what we mean, including under that head even dancing, singing, gesticulation, and performance on musical instruments. ~ George Henry Lewes
43:Now there are four chief obstacles in grasping truth, which hinder every man, however learned, and scarcely allow anyone to win a clear title to learning, namely, submission to faulty and unworthy authority, influence of custom, popular prejudice, and concealment of our own ignorance accompanied by an ostentatious display of our knowledge. ~ Roger Bacon
44:But we must here state that we should not see anything if there were a vacuum. But this would not be due to some nature hindering species, and resisting it, but because of the lack of a nature suitable for the multiplication of species; for species is a natural thing, and therefore needs a natural medium; but in a vacuum nature does not exist. ~ Roger Bacon
45:In the mathematics I can report no deficience, except that it be that men do not sufficiently understand the excellent use of the pure mathematics, in that they do remedy and cure many defects in the wit and faculties intellectual. For if the wit be too dull, they sharpen it; if too wandering, they fix it; if too inherent in the sense, they abstract it. ~ Roger Bacon
46:But concerning vision alone is a separate science formed among philosophers, namely, optics, and not concerning any other sense ... It is possible that some other science may be more useful, but no other science has so much sweetness and beauty of utility. Therefore it is the flower of the whole of philosophy and through it, and not without it, can the other sciences be known. ~ Roger Bacon
47:Roger Bacon expressed a feeling which afterwards moved many minds, when he said that if he had the power he would burn all the works of the Stagirite, since the study of them was not simply loss of time, but multiplication of ignorance. Yet in spite of this outbreak every page is studded with citations from Aristotle, of whom he everywhere speaks in the highest admiration. ~ George Henry Lewes
48:There are in fact four very significant stumbling blocks in the way of grasping the truth, which hinder every man however learned, and scarcely allow anyone to win a clear title to wisdom, namely, the example of weak and unworthy authority, longstanding custom, the feeling of the ignorant crowd, and the hiding of our own ignorance while making a display of our apparent knowledge. ~ Roger Bacon
49:The first known European book to describe the use of cryptography was written in the thirteenth century by the English Franciscan monk and polymath Roger Bacon. Epistle on the Secret Works of Art and the Nullity of Magic included seven methods for keeping messages secret, and cautioned: “A man is crazy who writes a secret in any other way than one which will conceal it from the vulgar. ~ Simon Singh
50:Alas,” mused Roger Bacon, “it is not only the public which so often fails to appreciate the nature of our more delicate investigations—many of our leading churchmen are particularly lacking in the finer faculties of discernment. Led by the twin banes of intolerance and ignorance, they too often condemn where they rightly should revere. They traduce what should be championed. They denounce what should be praised. ~ Stephen R Lawhead
51:As regards authority I so proceed. Boetius says in the second prologue to his Arithmetic, 'If an inquirer lacks the four parts of mathematics, he has very little ability to discover truth.' And again, 'Without this theory no one can have a correct insight into truth.' And he says also, 'I warn the man who spurns these paths of knowledge that he cannot philosophize correctly.' And Again, 'It is clear that whosoever passes these by, has lost the knowledge of all learning.' ~ Roger Bacon
52:After Bruno's death, during the first half of the seventeenth century, Descartes seemed about to take the leadership of human thought... in promoting an evolution doctrine as regards the mechanical formation of the solar system... but his constant dread of persecution, both from Catholics and Protestants, led him steadily to veil his thoughts and even to suppress them. ...Since Roger Bacon, perhaps, no great thinker had been so completely abased and thwarted by theological oppression. ~ Andrew Dickson White
53:No one really knew the sciences except the Lord Robert, Bishop of Lincoln, by reason of his length of life and experience, as well as of his studiousness and zeal. He knew mathematics and perspective, and there was nothing which he was unable to know; and at the same time he was sufficiently acquainted with languages to be able to understand the saints and the philosophers and the wise men of antiquity but his knowledge of languages was not such as to enable him to effect translations until the latter portion of his life. ~ Roger Bacon
54:forever. I would add to my reply as well, the borrowing of a simple invitation from the 13th-century English philosopher Roger Bacon: “Contemplate the world!” Because if we do not store in our heart a profound reverence for the miracles of nature as well as for the accomplishments of men and for their sometimes kind and illustrious way of thinking — even if our life is at its beginning and we have seen nothing yet; or if we’ve seen it all and find man evil — we will not be capable of recognizing those marvels, we will not be ~ Philippe Petit
55:First, by the figurations of art there be made instruments of navigation without men to row them, as great ships to brooke the sea, only with one man to steer them, and they shall sail far more swiftly than if they were full of men; also chariots that shall move with unspeakable force without any living creature to stir them. Likewise an instrument may be made to fly withall if one sits in the midst of the instrument, and do turn an engine, by which the wings, being artificially composed, may beat the air after the manner of a flying bird. ~ Roger Bacon
56:Grosseteste influenced Roger Bacon's ideas about mathematics and Nature. Bacon wrote hundreds of pages on the subject and, indeed, no historical figure has ever appeared more preoccupied with the question than he. He believed that mathematical knowledge was innate to the human mind and mathematics was a unique form of thought known both by ourselves and by Nature. Its uniqueness is characterized by the fact that it allows complete certainty to be achieved and hence our knowledge of Nature can be secure only in so far as we found it upon mathematical principles. ~ John D Barrow
57:All the men who are now called discoverers, in every matter ruled by thought, have been men versed in the minds of their predecessors, and learned in what had been before them. There is not one exception. I do not say that every man has made direct acquantance with the whole of his mental ancestry... But... it is remarkable how many of the greatest names in all departments of knowledge have been real antiquaries in their several subjects. I may cite among those... in science, Aristotle, Plato, Ptolemy, Euclid, Archimedes, Roger Bacon, Copernicus, Francis Bacon, Ramus, Tycho Brahe, Galileo, Napier, Descartes, Leibnitz, Newton, Locke. ~ Augustus De Morgan, A Budget of Paradoxes (1872)
58:It is only rather recently that science has begun to make peace with its magical roots. Until a few decades ago, it was common for histories of science either to commence decorously with Copernicus's heliocentric theory or to laud the rationalism of Aristotelian antiquity and then to leap across the Middle Ages as an age of ignorance and superstition. One could, with care and diligence, find occasional things to praise in the works of Avicenna, William of Ockham, Albertus Magnus, and Roger Bacon, but these sparse gems had to be thoroughly dusted down and scraped clean of unsightly accretions before being inserted into the corners of a frame fashioned in a much later period. ~ Philip Ball
59:[...] it is a strange thing that most of the feeling we call religious, most of the mystical outcrying which is one of the most prized and used and desired reactions of our species, is really the understanding and the attempt to say that man is related to the whole thing, related inextricably to all reality, known and unknowable. This is a simple thing to say, but the profound feeling of it made a Jesus, a St. Augustine, a St. Francis, a Roger Bacon, a Charles Darwin, and an Einstein. Each of them in his own tempo and with his own voice discovered and reaffirmed with astonishment the knowledge that all things are one thing and that one thing is all things—plankton, a shimmering phosphorescence on the sea and the spinning planets and an expanding universe, all bound together by the elastic string of time. It is advisable to look from the tide pool to the stars and then back to the tide pool again. ~ John Steinbeck
60:The moment they appeared on the scene, the first optical devices (Al-Hasan ibn al-Haitam aka Alhazen's camera obscura in the tenth century, Roger Bacon's instruments in the thirteenth, the increasing number of visual prostheses, lenses, astronomic telescopes and so on from the Renaissance on) profoundly altered the contexts in which mental images were topographically stored and retrieved, the impera- tive to re-present oneself, the imaging of the imagination which was such a great help in mathematics according to Descartes and which he considered a veritable part of the body, veram partem corporis. Just when we were apparently procuring the means to see further and better the unseen of the universe, we were about to lose what little power had of imagining it. The telescope, that epitome of the visual prosthesis, projected an image of a world beyond our reach and thus another way of moving about in the world, the logistics of perception inaugurating an unknown conveyance of sight that produced a tele- scoping of near and far, a phenomenon of acceleration obliterating our experience of distances and dimensions. ~ Paul Virilio
61:Books are not made to be believed, but to be subjected to inquiry. When we consider a book, we mustn’t ask ourselves what it says but what it means, a precept that the commentators of the holy books had very clearly in mind. The unicorn, as these books speak of him, embodies a moral truth, or allegorical, or analogical, but one that remains true, as the idea that chastity is a noble virtue remains true. But as for the literal truth that sustains the other three truths, we have yet to see what original experience gave birth to the letter. The literal object must be discussed, even if its higher meaning remains good. In a book it is written that diamond can be cut only with a billy goat’s blood. My great master Roger Bacon said it was not true, simply because he had tried and had failed. But if the relation between a diamond and goat’s blood had had a nobler meaning, that would have remained intact.” “Then higher truths can be expressed while the letter is lying,” I said. “Still, it grieves me to think this unicorn doesn’t exist, or never existed, or cannot exist one day.” “It is not licit to impose confines on divine omnipotence, and if God so willed, unicorns could also exist. But console yourself, they exist in these books, which, if they do not speak of real existence, speak of possible existence.” “So must we then read books without faith, which is a theological virtue?” “There are two other theological virtues as well. The hope that the possible is. And charity, toward those who believed in good faith that the possible was.” “But ~ Umberto Eco
