The Church and the Empire Part 6

[Sidenote: Conrad III.]

Lothair hoped to leave in his son-in-law a successor with irresistible claims. But the very influence to which Lothair owed his own election was now to be cast into the scale against the representative of his family; while the grounds of objection to the succession of Frederick of Hohenstaufen to Henry V now held good against Henry of Bavaria, Saxony, and Tuscany. The Pope and the German n.o.bles were equally afraid of a ruler whose insolent demeanour had already won him the t.i.tle of "the Proud." They took as their candidate the lately rejected Hohenstaufen Conrad, whose behaviour since his submission had gained him favour in proportion as the conduct of Henry of Bavaria had alienated the other n.o.bles. Conrad was crowned at Aachen by the papal legate, and Henry made his submission. But Conrad, like Lothair, felt himself insecure with so powerful a subject. Accordingly he took away from him the duchy of Saxony, and gave it to the heir of the old dukes in the female line. When Henry refused to accept the decision Conrad put him to the ban of the Empire and deprived him of Bavaria also, which he proceeded to confer upon a relative of his own. But Conrad's obvious attempt to advance his own family offended the n.o.bles, and the death of Henry the Proud in 1139 opened the way for a compromise.

Saxony was made over to Henry's youthful son, known in history as Henry the Lion, while Bavaria was to be the wedding portion of Henry the Proud's widow if she married Conrad's relative, who was already Margrave of Austria.

[Sidenote: Arnold of Brescia.]

But despite this elimination of all rivals Conrad was so much occupied elsewhere that he never managed to reach Italy. And yet his presence there was eagerly desired. It was under the guidance of their bishops that the cities of Lombardy had freed themselves from subjection to the feudal n.o.bles. But with the growth of wealth they resented the patronage of the bishops and were inclined to listen to those who denounced the temporal possessions of the Church. The movement spread to Rome. Here the munic.i.p.ality still existed in name, but it was quite overlaid by the papal prefect and the feudal n.o.bles of the Campagna; and the Roman people had no means of increasing their wealth by the agriculture or the commerce which was open to the cities of Tuscany or Lombardy. A leader was found in Arnold of Brescia (1138). He seems to have been a pupil of Abailard, who devoted himself to practical reforms. He began in his native Lombardy to advocate apostolic poverty as a remedy for the acknowledged evils of the Church. Condemned by the second Lateran Council (1139), he retired to France, and in 1140 stood by the side of Abailard at the Council of Sens. After Abailard's condemnation Arnold took refuge at Zurich, where, despite the denunciations of Bernard, he found protection from the papal legate, who had been a fellow-pupil of Abailard. Arnold returned to Italy in 1145, and was absolved by the Pope.

[Sidenote: The Roman Republic.]

The course of affairs in Rome brought him once more to the front. In 1143 Innocent II had offended the Romans, who in revenge proclaimed a republic with a popularly elected senate and a patrician in place of the papal prefect. Innocent died (September, 1143); his successor survived him by less than six months, and the next Pope, Lucius II, was killed in attempting to get possession of the Capitol, which was the seat of the new government. The choice of the Cardinals now fell upon the abbot of a small monastery in the neighbourhood of Rome, who took the t.i.tle of Eugenius III (1145-53). He was a pupil of Bernard, who feared for the appointment of a man of such simplicity and inexperience. But Eugenius developed an unexpected capacity, and forced the Romans to recognise for a time his prefect and his suzerainty. But Arnold's presence in Rome was an obstacle to permanent peace. Both Arnold and Bernard eagerly sought the same end--the purification of the Church. But in Bernard's eyes Arnold's connection with Abailard convicted him of heresy, and his doctrine of apostolic poverty was construed by the ascetic abbot of the strict Cistercian Order as an attack upon the influence under cover of the wealth of the Church. Nor was Arnold a republican in the ordinary sense. He expelled the Pope and organised, under the name of the Equestrian order, a militia of the lesser n.o.bles and the more substantial burgesses, such as existed in the cities of Lombardy. But he did not desire to repudiate the Emperor; and at his instigation the Romans summoned Conrad to their aid and to accept the imperial crown at their hands.

Eugenius spent almost his whole pontificate in exile; his successor, Anastasius IV, during a short reign, accepted the republic, but Hadrian IV (1154-9) took the first excuse for boldly placing the city for the first time under an interdict. The consequent cessation of pilgrims during Holy Week and the loss of their offerings caused the fickle Romans to expel their champion, and Arnold wandered about until a few months later Frederick Barbarossa sacrificed him to the renewed alliance of Empire and Papacy (1154).

[Sidenote: The second Crusade.]

Conrad III, then, never was crowned Emperor. It was no fault of his that he never visited Rome. Bernard's influence caused him to postpone his immediate duties for a work which every Christian of the time regarded as of paramount importance. The first Crusade had met with a measure of success only because the Mohammedan powers were divided.

The Crusaders were organised into the kingdom of Jerusalem and the princ.i.p.alities of Tripoli, Antioch, and Edessa. But they quarrelled incessantly. Meanwhile Imad-ed-din Zangi, the Atabek or Sultan of Mosul on the Tigris, extended his arms over all Mesopotamia and Northern Syria, and in 1144 he conquered the Latin princ.i.p.ality of Edessa. The whole of Europe was shocked at the disaster. Pope Eugenius delegated to Bernard the task of preaching a new crusade. The young King, Louis VII of France, had already taken the Crusader's vow, but so far the earnest entreaty of his minister, Suger, Abbot of St.

Denys, had kept him from his purpose. But at the Council of Vezelai in 1146 the eloquence of Bernard bore down all considerations of prudence. Conrad III was much harder to persuade, for he felt the need of his presence at home. But Bernard was not to be denied, and by working upon Conrad's feelings at the moment of the celebration of the Ma.s.s he entirely overcame the better judgment of the German King.

Events proved in every way the mischievous nature of Bernard's influence. The Crusade was a total failure. Only a small remnant of the force which followed either King reached Palestine; and the only offensive operation undertaken--an attack upon Damascus--had to be abandoned. Nothing had been done to break the growing power of Zangi's son, Noureddin, the uncle and predecessor of the great Saladin.

[Sidenote: The divorce of Louis VII.]

The effects were scarcely less disastrous in Western Europe. Suger supplied Louis with money and defended his throne against plots, and ultimately persuaded him to return to France. But during the Crusade Louis and his wife Eleanor, the daughter and heiress of William X of Aquitaine, had quarrelled bitterly. Louis had disgusted his high-spirited wife by behaving more like a pilgrim than a warrior; while Eleanor had attempted to divert the French troops to the aid of her uncle, Raymond of Antioch. Suger alone preserved some sort of harmony between the ill-a.s.sorted pair; but he died in 1151, and Bernard, who had never approved of the marriage on canonical grounds, lent his support to Louis' desire for a declaration of its invalidity, though Louis and Eleanor had been married for thirteen years and there were two daughters. The dissolution of the marriage was p.r.o.nounced by an ecclesiastical Council in 1152, and in the same year Eleanor, taking with her all her extensive lands, married the young Henry of Anjou and Normandy, who two years later became King of England.

[Sidenote: Bernard as defender of the Faith.]

Bernard and Suger were friends; but while the predominant work of Suger's life had been the supremacy of the House of Capet, it is vain to attempt to trace in Bernard any prejudice in favour of a growing French nationality. He represents the cosmopolitan Church of the Middle Ages; and his career is a supreme instance of the power which results from an absolutely single-minded devotion to a lofty cause. In masterful vehemence he challenges comparison with Hildebrand; but unlike the Pope, he never identified the Church with his own interests. He steadfastly refused all offers of advancement for himself, although he did not dissuade his own monks from accepting preferment. He would have preferred to live out his life as the obscure head of a poor and secluded community; and even if the political condition of the time had not brought constant appeals for help to him, his duty to the Church would have made him a public character. For the work of his life which was perhaps most congenial to him was the defence of the doctrine of the Church against heretical teachers. He has been called "the last of the Fathers," and his whole conception and methods were those of the great Christian writers of the early centuries. To the great saint self-discipline through obedience to the ordinances of the Church was the cure for all evil suggestions of the human heart; while as for the intellect, its duty was to believe the revealed faith as propounded by the authorities of the Church. Like St. Augustine, Bernard did not despise learning; but he would confine the term to the study of religion. Secular learning was for the most part not only a waste of precious time, but an actual snare of the devil. Thus Bernard stood for all that was most uncompromising in the theological att.i.tude of the time. Speculative discussion was an abomination; for the end of conversation was spiritual edification, not the advancement of knowledge; and what to strong minds might be mental gymnastics, in the case of weaker brethren caused the undermining of their faith. Against heretics of the commoner sort, such as the Petrobrusians, who impugned the whole system of the Church and appealed to the mere words of Scripture, there was only one line to be taken. But Bernard was no persecutor.

During his preaching of the Crusade a monk perverted the popular excitement to an attack upon the Jews in the cities of the Rhineland: Bernard peremptorily interfered and crushed the rival preacher.

Similarly with heretics. He trusted to his preaching--attested, as it was commonly supposed, by miracles--to convince the people; while the leaders when captured were subjected to monastic discipline.

[Sidenote: Abailard.]

But such popular forms of unbelief were merely the outcome of the speculations of subtler minds, which it was necessary to stop at the fountain-head. The arch-heretic of the time was Peter Abailard, who routed in succession two great teachers--William of Champeaux in dialectic in the great cathedral school of Paris, and Anselm of Laon, a pupil of Anselm of Canterbury, in theology. He gathered round him on the Mount of Ste. Genevieve, just outside Paris, a large band of students, in whom he inculcated his rationalistic methods. For his was a definite attempt to obtain by reason a basis for his faith. How could such teaching be allowed to continue unreproved by Bernard, who held that the sole office of the reason was to lead the mind astray?

But in the height of his fame Abailard, still quite young, loved the beautiful and erudite Heloise. He abused her trust, and when she in her infatuation for his genius refused to monopolise for herself by marriage the talents which were for the service of the world, she and he both entered the monastic life. Abailard pa.s.sed through several phases of this--a monk at St. Denys; a hermit gradually gathering a band of admirers round a church which they built and he dedicated to the Third Person of the Trinity, the Paraclete; and finally the abbot of a poor monastery in his own native Brittany. While an inmate of St.

Denys a work of his on the Trinity was condemned at a Council at Soissons presided over by the papal legate (1121). It was twenty years before he was again subjected to the censures of the Church. But, meanwhile, he had more than once fallen foul of Bernard, and had not hesitated to flout with his gibes the one man before whom the whole of Catholic Europe bent in awestruck reverence. But the time came when Bernard, noting the spread of the Petrobrusian heresy, determined to strike at the source of these errors. He appealed for a.s.sistance to the friends of orthodoxy from the Pope downwards. Abailard determined to antic.i.p.ate attack and desired to be heard before an a.s.sembly to be held at Sens (1140). Bernard reluctantly consented to take part in a public controversy. But when they met, Abailard, probably feeling himself surrounded by an unsympathetic audience, suddenly refused to speak and appealed to the Pope. On his way to Rome he fell ill at Cluny, where the saintly abbot, Peter the Venerable, received him as a monk. He made a confession which chiefly amounted to a regret that he had used words open to misconstruction, and he died in 1142 the inmate of a Cluniac house.

Bernard remained upon the alert, intent on checking any further spread of the teaching of Abailard's followers. But he had pushed matters to an extreme, and there were many in high place who resented his efforts to dictate the doctrine of the Church. Thus Gilbert de la Porree, Bishop of Poictiers, a pupil of Abailard, was accused at the Council of Rheims (1148) of erroneous doctrines regarding the being of G.o.d and the Sacraments. Bernard tried to use his influence over Pope Eugenius in order to procure the bishop's condemnation, and stirred up the French clergy to a.s.sist him. The Cardinals addressed an indignant remonstrance to the Pope, pointing out that as he owed his elevation from a private position to the papacy to them, he belonged to them rather than to himself, that he was allowing private friends.h.i.+p to interfere with public duty, and that "that abbot of yours" and the Gallican Church were usurping the function of the See of Rome. Bernard had to explain away the action of his party, and the Council contented itself with exacting from the accused a general agreement with the faith of the Roman Church, and this was represented by Gilbert's friends as a triumph.

Bernard's death restored the leaders.h.i.+p of Christendom to the official head, and the removal of several others of the chief actors of the time opened the way not only for new men, but for the emergence of new questions. In 1152 Conrad III ended his well-intentioned but somewhat ineffectual reign. In 1153 Pope Eugenius died at Rome, to which he had at length been restored a few months previously. Six weeks later St.

Bernard followed him to the grave. It was not long before the papal act ratified the general opinion of Christendom, and in 1174 Alexander III placed his name among those which the Church desired to have in everlasting remembrance.

CHAPTER VII

THE SCHOOLMEN AND THEOLOGY

[Sidenote: Secular Studies.]

Mediaeval learning, whether sacred or secular, was founded upon authority. The Scholasticus, who took the place of the ancient Grammaticus, was not an investigator, but merely an interpreter. On the one side the books of the sacred Scriptures as interpreted by the Fathers were the rule of faith; on the other side as the guide of reason stood the works of the Philosopher, as Aristotle was called in the Middle Ages. But until the thirteenth century few of his works were known, and those only in Latin translations. Here were the materials, slight enough, on which hung future development. The secular knowledge taught in the ordinary schools was that represented by the division of the Seven Arts into the elementary Trivium of Grammar, Rhetoric, Dialectic, followed by the Quadrivium of Music, Arithmetic, Geometry, and Astronomy. The scope of the Trivium was much wider than the terms denote. Thus Grammar included the study of the cla.s.sical Latin authors, which never entirely ceased; Rhetoric comprised the practice of composition in prose and verse, and even a knowledge of the elements of Roman Law; Dialectic or Logic became the centre of the whole secular education, because it was the only intellectual exercise which was supposed to be independent of pagan writers. In the Quadrivium--the scientific education of the time--Arithmetic and Astronomy were taught for the purpose of calculating the times of the Christian festivals; Music consisted chiefly of the rules of plain-song. It was the subjects of the Quadrivium which were subsequently enlarged in scope by the discoveries of the twelfth century. Apart from these subjects little attempt was made at a systematic training in theology. In so far as any such existed it was purely doctrinal, and aimed merely at enabling those in Holy Orders to read the Bible and the Fathers for themselves and to expound them to others.

[Sidenote: Scholasticism.]

Now the speculative intellect trained in dialectic had no material to work upon save what could be got from the Scriptures, the Fathers, and the dogmas of the Church; and Scholasticism is the name given to the attempt to apply the processes of logic to the systematisation and the interpretation of the Catholic faith. The movement was one which, narrow as it seems to us, yet made for ultimate freedom of human thought; for it meant the exercise of the intellect on matters which for long were regarded as beyond the reach of rationalistic explanation. There was much difference of opinion among the thinkers as to the limits to be a.s.signed to such freedom of speculation on the mysteries of the faith, some starting from the standpoint of idealists and endeavouring to avoid the logical consequences of their speculations; while others, adopting so far as possible a position of pure empiricism, set tradition at defiance, and hoped by the aid of reason to reach the conclusions of divine revelation.

[Sidenote: Realists and Nominalists.]

The philosophical problem to which the mediaeval thinkers addressed themselves is one that it is essential to the progress of human thought to solve. Whence do we derive general notions (Universals, as they were called), and do they correspond to anything which actually exists? Thus for the purpose of cla.s.sifying our knowledge we use certain terms, such as genera, species, and others more technical. Do these in reality exist independently of particular individuals or substances? One school of philosophers, basing their reasoning upon Plato, maintained that such general ideas had a real existence of their own, and hence gained the name of Realists. But another school, who took Aristotle as their champion, held that reality can be a.s.serted of the individual alone, that there is nothing real in the general idea except the name by which it is designated; while some of these Nominalists, as they came to be called, even proclaimed that the parts of an individual whole were mere words, and could not be considered as having an existence of their own. With the application of these definitions to theological dogmas we reach the beginning of Scholastic Theology. Here both sides were soon landed in difficulties.

Nominalism, in its denial of reality to general notions, undermined the Catholic idea of the Church: in its recognition of none except individuals it destroyed the whole conception of the solidarity of original sin; while those of its professors who allowed no existence of their own to the parts of an individual whole, resolved the Trinity into three G.o.ds. On the other hand, the danger of Realism was that, since individuals were regarded merely as forms or modes of some general idea, these philosophers were inclined to make no distinction between individuals and to fall into pantheism. As a result, the personality of man, and with it the immortality of the soul, disappeared, and even the personality of G.o.d threatened to lose itself in the universe which He had created. These tendencies will be clear from a short account of the chief schoolmen or writers on Scholastic Philosophy.

[Sidenote: Roscelin and Anselm.]

The first great names are those of Roscelin and Anselm of Canterbury.

Roscelin (between 1050 and 1125), primarily a dialectician, rigidly applied his logic to theological dogmas. If we may judge from the accounts of his opponents, Anselm and Abailard, he took up a position of extreme individualism and denied reality alike to a whole and to the parts of which any whole is commonly said to be composed. The application of this principle to the doctrine of the Trinity landed him in tritheism, and he did not shrink from the reproach. Roscelin, a theologian by accident, was answered by Anselm who was primarily a theologian, and a dialectician by accident. If Roscelin was the founder of Nominalism Anselm identified Realism with the doctrine of the Church. But Anselm's Realism is not the result of independent thought. In his methods he has been rightly styled the "last of the Fathers." His keynote was Belief in the Christian faith as the road to understanding it. Thus his object was to give to the dogmas accepted by the Church a philosophical demonstration. To him Realism was the orthodox philosophical doctrine because it was the one most in harmony with Christian theology. He applied philosophical arguments to the explanation of those tenets of the faith which later scholastic writers placed among the mysteries to be accepted without question.

[Sidenote: Abailard.]

The reputed founder of definite Realism was William of Champeaux (1060-1121), a pupil of Roscelin himself, a teacher at Paris, and ultimately Bishop of Chalons. By the account of his enemy Abailard, he held an uncompromising Realism which maintained that the Universal was a substance or thing which was present in its entirety in each individual. It was the presence of such crude Realism as this which gave his opportunity to the greatest teacher of this early period of Scholasticism, Peter Abailard (1079-1142). A pupil of both Roscelin and William of Champeaux--the two extremes of Nominalism and Realism--he aimed in his teaching at arriving at a _via media_ to which subsequent writers have given the name Conceptualism. According to him the individual is the only true substance, and the genus is that which is a.s.serted of a number of individuals; it is therefore a name used as a sign--a concept, although he does not use the word.

Thus he does not condemn the Realistic theory borrowed from Plato, of Universals as having an existence of their own; he regards them as ideas or exemplars which existed in the divine mind before the creation of things. But he opposes the tendency in Realism to treat as identical the qualities which resemble each other in different individuals, since that abolishes the personality of the individual which to him is the only reality. Like Roscelin he did not hesitate to apply his dialectic to theology. Here, while repudiating the tritheism of his master, he practically reproduced the old heresy of Sabellius which reduced the Trinity to three aspects or attributes of the Divine Being--power, wisdom, and love. "A doctrine is to be believed," he held, "not because G.o.d has said it, but because we are convinced by reason that it is so." His whole att.i.tude was that of the free, if reverent, enquirer. "By doubt," he says, "we come to enquiry; by enquiry we reach the truth." His book _Sic et Non_, a collection of conflicting opinions of the Christian Fathers on the chief tenets of the faith, was to be the first step towards arriving at the truth.

[Sidenote: Mysticism.]

He was condemned twice--his doctrine of the Trinity at Soissons in 1121, his whole position at Sens in 1141. The leaders of orthodoxy met him not with argument but with a demand for recantation. St. Norbert during the early part of his life, and St. Bernard both early and late, pursued him with their enmity. Their objection was not to his particular views, but to his whole att.i.tude towards divine revelation; and the conclusions in which the use of the scholastic method landed its advocates perhaps justified the rigid theologians in the general distrust of the exercise of reason on such subjects. St. Bernard did not hesitate to attack even Gilbert de la Porree, Bishop of Poictiers, an avowed Realist, who attempted to explain the Trinity. In fact, St.

Bernard represents the reaction from Scholasticism, which took the form of Mysticism, that is, the purely contemplative att.i.tude towards the verities of the Christian creed. In this he was followed with much greater extravagance by the school which found its home in the great abbey of St. Victor--Hugh (1097-1143), who formulated the sentence "Knowledge is belief, and belief is love," and Richard (died in 1173), who applied to the intuitive perception of spiritual things and to the love of them the same dialectical and metaphysical methods as the Schoolmen applied to reason.

[Sidenote: After Abailard.]

The results of Abailard's work are seen in two directions. His _Sic et Non_ became the foundation of the work of the "Summists," who, in the place of Abailard's purely critical work, occupied themselves in systematising authorities with a view to the reconciliation of their conflicting opinions. The greatest of these was Peter the Lombard (died 1160), who became Bishop of Paris, and whose _Sententiae_ was taken as the accredited text-book of theology for the next three hundred years. With the Summists theology returned to its att.i.tude of unquestioning obedience to the conclusions of the early Fathers. But in the second place, Abailard was indirectly responsible for "the troubling of the Realistic waters," which resulted in many modifications of the original position.

[Sidenote: Cla.s.sical revival.]

A justification for the att.i.tude of the Church towards the followers of Abailard is to be found in the apparent exhaustion of the speculative movement which had started at the end of the eleventh century, and the consequent degeneracy of logical studies. It was a result of this that in the second half of the twelfth century many of the best minds were directing their energies into the channel of cla.s.sical learning which was to prepare the way for the next phase of Scholasticism. Besides being a philosopher and a theologian, Abailard was also a scholar well read in cla.s.sical literature. The cathedral school of Chartres, founded by Fulbert at the beginning of the eleventh century, was the centre of this cla.s.sical Renaissance, and it rose to the height of its fame under Bernard Sylvester and his pupil, William of Conches; while the greatest representative of this learning was a pupil of William of Conches, John of Salisbury, an historian of philosophy rather than himself a philosopher or theologian.

[Sidenote: Origin of universities.]

It was in the twelfth century and out of the cathedral schools that the medieval universities arose. The monastic schools had spent their intellectual force, and during this century they almost ceased to educate the secular clergy. St. Anselm, when Abbot of Bec in Normandy, was the last of the great monastic teachers. But it was not from the school of Chartres but from that of Paris that the greatest University of the Middle Ages took its origin. Paris was identified with the scholastic studies of dialectic and theology, and it was the fame of William of Champeaux, and still more that of Abailard, which drew students in crowds to the cathedral school of Paris. But no university immediately resulted. Indeed, the Guild of Masters, from which it originated, is not traceable before 1170, and the four Nations and the Rector did not exist until the following century. Its recognition as a corporation dates from a bull of Innocent III about 1210. Its development starts from the close of its struggle with the Chancellor and cathedral school of Paris, in which contest it obtained the papal help. Before the middle of the thirteenth century the University had acquired its full const.i.tution. But its great fame as a place of education dates from the teaching of the two great Dominicans, Albertus Magnus and Thomas Aquinas in the convent of their Order in Paris during the middle years of the century. This new outburst of philosophical studies was due to the recovery of many hitherto unknown works of Aristotle, and as a consequence cla.s.sical studies were completely neglected and Chartres was deserted for Paris.

[Sidenote: Aristotle in the East.]

We have seen that the contemporaries of Abailard knew none but Aristotle's logical works, and these only in part and in Latin translations. So far nothing had interfered with the development of thought along "purely Western, purely Latin, purely Christian" lines.

Churchmen who did not disapprove of dialectic altogether, had accepted and used Aristotle so far as they understood what they had of his works. Heretics there had been, but hitherto none had questioned the authority of the Bible or the Church. Meanwhile in the east a completer knowledge of Aristotle's works had been communicated by the Nestorian Christians to their Mohammedan masters. Greek books were translated into Arabic, and Arabian philosophy, already monotheistic, became permeated with Aristotelian ideas. Moreover, the union of philosophical and medical studies among the Arabs caused them to attach a special value to Aristotle's treatises on natural science. In Spain the Arabs handed on their knowledge of Aristotle to the Jews, and it was from the Jews of Andalusia, Ma.r.s.eilles, and Montpellier that the works of the Greek philosopher and his Arabian commentators became known in the west.

[Sidenote: Revival in the west.]

By the middle of the twelfth century the chief of these works--texts, paraphrases, commentaries--had, at the instance of Raymond, Archbishop of Toledo, been rendered into Latin by Archdeacon Dominic Gondisalvi, a.s.sisted by a band of translators. But the translations of Aristotle's own works were not from the original Greek, but from the Arabic, which laid stress upon the most anti-Christian side of Aristotle's thought, such as the eternity of the world and the denial of immortality. The result was an outbreak of heretical speculation along pantheistic lines. Swift steps were taken: the heretics were hunted down, and in 1209 the Council of Paris forbade the study of Aristotle's own works or those of his commentators which dealt with natural philosophy; while in 1215 the statutes of the University renewed the prohibition.
