at each University. The Oxford Dominicans lectured on theology in the nave of their new church while philosophy was taught in the cloister. The first provincial of the Grey Friars built a school in their Oxford house and persuaded Grosseteste to lecture there. His influence after his promotion to the see of Lincoln was steadily exerted to secure theological study among the Friars, as well as their establishment in the University; and in this work he was ably seconded by his scholar, Adam Marsh, or de Marisco, under whom the Franciscan school at Oxford attained a reputation throughout Christendom. Lyons, Paris, and Koln borrowed from it their professors: it was through its influence indeed that Oxford rose to a position hardly inferior to that of Paris itself as a centre of scholasticism. But the result of this powerful impulse was soon seen to be fatal to the wider intellectual activity which had till now characterized the Universities. Theology in its scholastic form resumed its supremacy in the schools. Its only efficient rivals were practical studies such as medicine and law. The last, as he was by far the greatest, instance of the freer and wider culture which had been the glory of the last century, was Roger Bacon, and no name better illustrates the rapidity and completeness with which it passed away.
Roger Bacon
Roger Bacon was the child of royalist parents who were driven into exile and reduced to poverty by the civil wars. From Oxford, where he studied under Edmund of Abingdon to whom he owed his introduction to the works of Aristotle, he passed to the University of Paris, and spent his whole heritage there in costly studies and experiments. "From my youth up," he writes, "I have laboured at the sciences and tongues. I have sought the friendship of all men among the Latins who had any reputation for knowledge. I have caused youths to be instructed in languages, geometry, arithmetic, the construction of tables and instruments, and many needful things besides." The difficulties in the way of such studies as he had resolved to pursue were immense. He was without instruments or means of experiment. "Without mathematical instruments no science can be mastered," he complains afterwards, "and these instruments are not to be found among the Latins, nor could they be made for two or three hundred pounds. Besides, better tables are indispensably necessary, tables on which the motions of the heavens are certified from the beginning to the end of the world without daily labour, but these tables are worth a king's ransom and could not be made without a vast expense. I have often attempted the composition of such tables, but could not finish them through failure of means and the folly of those whom I had to employ." Books were difficult and sometimes even impossible to procure. "The scientific works of Aristotle, of Avicenna, of Seneca, of Cicero, and other ancients cannot be had without great cost; their principal works have not been translated into Latin, and copies of others are not to be found in ordinary libraries or elsewhere. The admirable books of Cicero de Republica are not to be found anywhere, so far as I can hear, though I have made anxious enquiry for them in different parts of the world, and by various messengers. I could never find the works of Seneca, though I made diligent search for them during twenty years and more. And so it is with many more most useful books connected with the science of morals." It is only words like these of his own that bring home to us the keen thirst for knowledge, the patience, the energy of Roger Bacon. He returned as a teacher to Oxford, and a touching record of his devotion to those whom he taught remains in the story of John of London, a boy of fifteen, whose ability raised him above the general level of his pupils. "When he came to me as a poor boy," says Bacon in recommending him to the Pope, "I caused him to be nurtured and instructed for the love of God, especially since for aptitude and innocence I have never found so towardly a youth. Five or six years ago I caused him to be taught in languages, mathematics, and optics, and I have gratuitously instructed him with my own lips since the time that I received your mandate. There is no one at Paris who knows so much of the root of philosophy, though he has not produced the branches, flowers, and fruit because of his youth, and because he has had no experience in teaching. But he has the means of surpassing all the Latins if he live to grow old and goes on as he has begun."
The pride with which he refers to his system of instruction was justified by the wide extension which he gave to scientific teaching in Oxford. It is probably of himself that he speaks when he tells us that "the science of optics has not hitherto been lectured on at Paris or elsewhere among the Latins, save twice at Oxford." It was a science on which he had laboured for ten years. But his teaching seems to have fallen on a barren soil. From the moment when the Friars settled in the Universities scholasticism absorbed the whole mental energy of the student world. The temper of the age was against scientific or philosophical studies. The older enthusiasm for knowledge was dying down; the study of law was the one source of promotion, whether in Church or state; philosophy was discredited, literature in its purer forms became almost extinct. After forty years of incessant study, Bacon found himself in his own words "unheard, forgotten, buried." He seems at one time to have been wealthy, but his wealth was gone. "During the twenty years that I have specially laboured in the attainment of wisdom, abandoning the path of common men, I have spent on these pursuits more than two thousand pounds, not to mention the cost of books, experiments, instruments, tables, the acquisition of languages, and the like. Add to all this the sacrifices I have made to procure the friendship of the wise and to obtain well-instructed assistants." Ruined and baffled in his hopes, Bacon listened to the counsels of his friend Grosseteste and renounced the world. He became a friar of the order of St. Francis, an order where books and study were looked upon as hindrances to the work which it had specially undertaken, that of preaching among the masses of the poor. He had written little. So far was he from attempting to write that his new superiors prohibited him from publishing anything under pain of forfeiture of the book and penance of bread and water. But we can see the craving of his mind, the passionate instinct of creation which marks the man of genius, in the joy with which he seized a strange opportunity that suddenly opened before him. "Some few chapters on different subjects, written at the entreaty of friends," seem to have got abroad, and were brought by one of the Pope's chaplains under the notice of Clement the Fourth. The Pope at once invited Bacon to write. But difficulties stood in his way. Materials, transcription, and other expenses for such a work as he projected would cost at least, £60, and the Pope sent not a penny. Bacon begged help from his family, but they were ruined like himself. No one would lend to a mendicant friar, and when his friends raised the money he needed it was by pawning their goods in the hope of repayment from Clement. Nor was this all; the work itself, abstruse and scientific as was its subject, had to be treated in a clear and popular form to gain the Papal ear. But difficulties which would have crushed another man only roused Roger Bacon to an almost superhuman energy. By the close of 1267 the work was done. The "greater work," itself in modern form a closely-printed folio, with its successive summaries and appendices in the "lesser" and the "third" works (which make a good octavo more), were produced and forwarded to the Pope within fifteen months.
The Opus Majus
No trace of this fiery haste remains in the book itself. The "Opus Majus" is alike wonderful in plan and detail. Bacon's main purpose, in the words of Dr. Whewell, is "to urge the necessity of a reform in the mode of philosophizing, to set forth the reasons why knowledge had not made a greater progress, to draw back attention to sources of knowledge which had been unwisely neglected, to discover other sources which were yet wholly unknown, and to animate men to the undertaking by a prospect of the vast advantages which it offered." The developement of his scheme is on the largest scale; he gathers together the whole knowledge of his time on every branch of science which it possessed, and as he passes them in review he suggests improvements in nearly all. His labours, both here and in his after works, in the field of grammar and philology, his perseverance in insisting on the necessity of correct texts, of an accurate knowledge of languages, of an exact interpretation, are hardly less remarkable than his scientific investigations. From grammar he passes to mathematics, from mathematics to experimental philosophy. Under the name of mathematics indeed was included all the physical science of the time. "The neglect of it for nearly thirty or forty years," pleads Bacon passionately, "hath nearly destroyed the entire studies of Latin Christendom. For he who knows not mathematics cannot know any other sciences; and what is more, he cannot discover his own ignorance or find its proper remedies." Geography, chronology, arithmetic, music, are brought into something of scientific form, and like rapid sketches are given of the question of climate, hydrography, geography, and astrology. The subject of optics, his own especial study, is treated with greater fulness; he enters into the question of the anatomy of the eye besides discussing problems which lie
