The influence of the study of Aristotle was telling vitally upon the theology of the schools. At first his writings were studied through very imperfect translations made from the Arabic, with Arabic commentaries—then a mixture of Neo Platonism was infused, and the devotees of scholastic theology at Paris fell into such errors that the study of his works was prohibited by the synod of that place in the year 1209. Six years afterward this prohibition was renewed by the Papal Legate; but as men began to find that there was a great difference between the philosophy of Aristotle, filtered through Arabic commentators and Arabic translators, and Aristotle himself, a revival took place in favor of the Stagyrite, and Gregory IX., in 1231, by a bull modified the restriction. New translations were now made and purged from errors.

A new era in scholasticism commenced; the two rival orders, the Dominicans and Franciscans, began to apply the Aristotelian method to theological questions; Albertus Magnus and Thomas Aquinas [Footnote 160] taking the lead in the former order, in opposition to the teaching of Alexander Hales.[Footnote 161] the Franciscan, who lectured at Paris. Bonaventura [Footnote 162] endeavored to amalgamate scholasticism with mysticism; but at length appeared John Duns Scotus, [Footnote 163] who lectured at Oxford, Paris, and Cologne, a Franciscan, and worthy opponent of the Dominican, Thomas Aquinas. We must not omit another distinguished member of the Oxford school who flourished at the same time, Roger Bacon, [Footnote 164] perhaps the most distinguished man of the age.

He taught at Oxford. He, however, saw the prominent errors of the disputation of the times, and has left on record, in the preface to his Opus Majus, the following criticism, which is worthy of attention: "There never was such an appearance of wisdom, nor such activity in study in so many faculties, and so many regions, as during the last forty years; for even the doctors are divided in every state, in every camp, and in every burgh, especially through the two studious orders, (Dominicans and Franciscans,) when neither, perhaps, was there ever so much ignorance and error. The mob of students languishes and stupefies itself over things badly translated; it loses time and study; appearances only hold them, and they do not care what they know so much as what they seem to know before the insensate multitude."

Again, in lib. ii., he says: "If I had power over the books of Aristotle, I would have them all burnt, because it is only a loss of time to study in them, a cause of error and multiplication of ignorance beyond what I am able to explain." We must give Roger Bacon the credit of speaking more particularly of the wretched translations in use, though his view of Aristotelian philosophy was strangely confirmed centuries afterward by his still greater namesake, Lord Bacon, who said, after many years of devotion to Aristotelianism, that it was "a philosophy only strong for disputations and contentions, but barren of the production of works for the benefit of the life of man." Thus were ranged under two scholastic standards the two great orders of mendicant friars, the Dominicans and the Franciscans; the former being called Thomists, and the latter Scotists. A fierce doctrinal controversy then raged between them, the animosity of which was heightened by a jealousy which had always existed on the part of the Dominicans from the time when St. Francis rejected their founder's overtures to unite the two orders.
