The 13th Century

The 13th c. saw the development of the urban schools into universities, an institution where knowledge was produced (and not simply transmitted); the first universities were founded in Bologna, Paris and Oxford. The university is an autonomous institution, structured as a guild (or corporation) of arts, with some original characteristics such as: the faculties, divided into broad disciplinary departments; and the ‘nations’ (something analogous to modern colleges), which reflected the origins and the mother-tongues of the students, while Latin remained the official language of teaching for many more centuries to come. The faculty of arts, that was the first one attended by each university student, included the teaching of philosophy, which had been codified at the end of the previous century following the Aristotelian divisions, metaphysics, physics and ethics; while the three superior faculties (that perhaps now would be called ‘professional’) provided the teaching of theology, medicine, and law (Roman and canon). The knowledge produced in this one-genedere (male) environment is characterized by its competitive and dialogical form (its most representative literary genre being the quaestio), with witty elements alongside critical ones. The philosophic sources acquired in the previous century are now assimilated through a detailed critical works (the commentaries), and enriched with new translations of texts, mostly from the Greek (the commentaries on Aristotle by Neoplatonic authors (Ammonius and Philoponus) and Byzantine authors (Eustratius of Nicea and Michael of Ephesus), translated by Robert of Lincoln (Grosseteste) (d. 1253); Proclus, translated by William of Moerbeke, to whom we also owe the complete revision of the translations of Aristotelian texts). With respect to the East, the 13th c. is seen as a time of closing, both towards the Islamic world (1210, 1270 and 1277: condemnations of Aristotelianism and Arabism) and towards the Greek-Byzantine world (condemnation of the Greek notion of the beatific vision). The large extent to which the logica modernorum was used lead to the discovery of new arguments in theology and science, fields that towards the end of the century were consistently starting to create cracks in the unity of the Aristotelian system. The birth of the mendicant orders produced a change in the way spiritual issues were perceived, and in particular with respect to the Dominican order, which proposed itself as the bulwark of the Christian faith against heresies and Islam: philosophy was even ‘recruited’ against the infidels, as Raymond de Penyafort shows in his activity, which heavily influenced the Summa contra Gentiles of Thomas Aquinas (1225-1274) and the entire apologetic work of Ramon Lull (1235-1315) .

The fist half of the century is characterized by the initial condemnation of Aristotelian philosophy, and then later on by its gradual assimilation into the official culture. In this process it is crucial to understand the attitudes of theologians (William of Auxerre, d. 1131;Philip the Chancellor, d. 1136; William of Auvergne d. 1245), who began a scientific dialogue on theology and its relations with metaphysics; and the attitude of the masters of Arts, to whom we owe a new understanding of the philosophic writings of Aristotle mediated through the use of the commentaries of Avicenna and Averroes. Both of these trends culminated in the works of Albert the Great (c. 1200-1280), who was called the Doctor universalis for his broad range of interests. His teaching produced various doctrinal evolutions: the Averroism of Siger of Brabant; the synthesis between Aristotle and Christianity of Thomas Aquinas; the Neoplatonic-Dyonisian themes and the bond between the concepts of a philosophic life and of mystical experience, which define the following German philosophy and especially the works of Eckhart (1260-1327). Around the middle of the century, an important institutional innovation took place: the two mendicant orders, the Dominicans and the Franciscans, having been created at the beginning of the century in response to well-defined spiritual needs (namely, the former for the struggle against heretics, and the latter for the desire of evangelic poverty), fully joined the academic life, after a period of harsh polemics with the secular masters. Albert the Great was a Dominican, as well as Thomas and Eckhart. The Franciscan masters of Arts and theology participated in the same process of cultural evolution, but with different positions, being more critical and aware of the implicit risks in accepting Aristotelian philosophy from a Christian point of view. The more representative figures of this tendency were in the first half of the century, Alexander of Hales (c. 1170-1245) and John of La Rochelle (c. 1190-1245); and in the next generation Bonaventure of Bagnorea (1217-74) who held the Franciscan chair of theology at the same time in which Thomas Aquinas was holding the Dominican one, and who proposed an original reflection on the position of the theologian at work in the context of Aristotelian philosophy, as well as a synthesis of metaphysical and spiritual (mystic) themes, centered on the symbolic transparency as a manifestation of God, and in particular on the theme of light. In the context of the Faculty of Arts, another Franciscan friar had begun his own philosophic reflection, Roger Bacon (c. 1215-1294), who soon developed an original and harshly critical attitude towards his contemporaries (especially towards Albert the Great), proposing a reform of studies that would form the basis and the principal tool of a deep reformation of the whole of Christendom. To this end, Bacon emphasized the need to assume a critical attitude in the investigation of reality (scientia experimentalis), not limiting himself to the knowledge learnt from the authoritative texts. A different reformation proposal, focused on the intuition of a non-Aristotelian method of demonstration, came from Ramon Lull (1235-1315), a layman, even though holding positions near to the Franciscans. The diffusion of philosophy outside the universities is demonstrated by the works of Dante Alighieri (1265-1315) and, in a different way, by the writings of Eckhart: his German sermons, as well as Dante’s use of Italian in the Convivio and of Lull’s use of Catalan in various works, constitute the first examples of an original philosophic production in the vernacular. In the final decades of the century, these philosophic positions were refined and diversified, thus giving way to a complex period, characterized by many important doctrinal debates: the debate against the Averroists (focused on two main points of dispute with Aristotelian philosophy: the unity of the possible intellect and the eternity of the world); the debate for and against Thomism (which eventually became the ‘official’ doctrine of the Dominicans only at the beginning of 14th c.); and in particular the debate on the unity of the substantial form, a position opposed to hylomorphism.

In the Islamic world the diffusion of Aristotelian philosophy went on for the whole century, but without influencing Latin culture, since none of the writers during the Mongol dynasty (Nasir al-Din al Tusi, 1201-1274; Ibn Taymiyya, 1263-1328; and Iji, 1281-1355) were translated into Latin. Even the dialogue with the philosophers of al-Andalus was reduced to the letters sent by Ibn Sabin (1218-1270) to Frederick II, in which the themes fundamental even for Scholastic philosophy recur: the eternity of the world, the possibility of theology, the structure of being in categories, the problem of the individual soul and of personal immortality, and the relationship between reason and revelation. Through the court of Frederick II and thanks to the work of Michael Scot, the translation of the Aristotelian commentaries of Averroes came to be known to the Latin world. And it was in Sicily and through the intellectual circle born around the papal court in the middle of the century that scientific interests on optics, astronomy, and alchemy were diffused, all of which focused on a new positive evaluation of corporeality and on related texts. Various Scholastic authors (above all Albert the Great and Roger Bacon) showed a strong interest for these themes before the end of the century, when the concentration on theological, metaphysical and logical problems and the tendency toward specialization created a strong rupture between the ‘knowledge of the bodies’ on the one hand, and philosophic, scientific, and institutional research on the other. Almost absent in this period is any philosophic exchange with Byzantium, where the prevalent interest was still in Neoplatonic philosophy. Instead, interaction with Jewish philosophy becomes more complex and hard to grasp, both because of the increasing Antisemitism which rendered more difficult relationships between the Christian and Jewish worlds, and because Jewish philosophers active in Provence and Catalunia wrote mainly in their own languages (Samuel ibn Tibbon, d. 1232; the group of translators from Lunel; Shemtob ben Joseph ibn Falaqera, 1223/5-post-1291, who translated into Hebrew the Guide of the Perplexed; the Averroist Isaac Albalag, active in the last decades of the century; and the Spanish Kabbalists Ezra and Azriel of Gerona, Moses Maimonides, Jehuda Cohen, and Abraham Abulafia). However, significant exchanges still took place among the Italian intellectual environments.
