About 1256 Averroes’ teaching about the unity of intelligences was sufficiently widespread at Paris to induce Albertus to write his treatise “On the unity of the intellect against the Averroists,” a treatise which he afterwards inserted in his Summa. In 1269 certain propositions from Averroes were formally condemned. At this time his works were well known, and there was a distinct party at Paris which had adopted his views and which we may describe as a semi-Judaistic party. This time both Albertus and St. Thomas published treatises against the doctrine of the unity of intelligences. Again in 1277 various Averroist theses were condemned at Paris, for the most part emanating from the Franciscans, who, as Bacon notes (opus Tert. 23), were strongly inclined towards Averroes both at Paris and in England, a condition which prevailed until the great Franciscan doctor Duns Scotus (d. 1308) took a definitely anti-Averroist line. Still, even in the 14th century, when Averroism was practically dead at Paris, it still retained its hold amongst the Franciscans in the English “nation.” The Dominicans were less favourably disposed towards the Arabic writers, at least after the time of Albertus, and show a much more careful estimate of their work. This was no doubt due to the fact that they had a house of Arabic studies in Spain, and were actually engaged in controversy with the Muslims. As a rule a careful distinction is drawn between Averroes the commentator, who is treated with great respect as an exponent of the text of Aristotle, and Averroes the philosopher, who is regarded as heretical. It seems as though there was a deliberate policy to secure Aristotle by sacrificing the Arabic commentators. Very characteristic of the work of the Dominicans was the _Pugio Fidei adversum Mauros et Judaeos_ of Raymund Martini, who lived in Aragon and Provence; he was familiar with Hebrew, and freely uses the Hebrew translations of the Arabic philosophers. His arguments are largely borrowed from al-Ghazali’s _Destruction of the Philosophers_. It is curious to note that, in his anxiety to defend Aristotle, he accuses Averroes of borrowing the doctrine of the unity of intelligences from Plato, and in a sense there was an element of truth in this, for the Averroist doctrine was ultimately derived from neo-Platonic sources. Raymund also cites the medical teaching of Averroes at a date earlier than any Latin version, and here again shows familiarity with the Hebrew translations. John Baconthorp (d. 1346), the provincial of the English Carmelites and “doctor” of the Carmelite order, tends to palliate the heretical tendencies of Averroes’ teaching, and was called by his contemporaries “the prince of Averroists,” a title which was apparently regarded as a compliment.
