Literacy and elementary learning became more widespread after 1000. Indeed, the growth in literacy was heralded by the heresy of Vilgard of Ravenna, who, according to Radulfus Glaber, was betrayed by demons in the guise of Virgil and other ancient writers in the late 10th century. By the later 11th and the 12th century, cathedral schools had emerged as centres of learning, and literacy had become an increasingly important tool of government. A form of Christian humanism took shape in the 12th century that was expressed in the letters of John of Salisbury and others. The courtly tastes of the 12th century, while not obliterated, were overtaken by a more flexible and ironic sensibility evident in vernacular ballads, fables, satires, and moralizing literature, most popular in the northern towns. The burgher or knight began to take a keen interest in the tangible world about him. The taste for clarity, proportion, and articulation reached mature expression in the great Gothic cathedrals of northern France, such as those in Amiens, Paris (Notre-Dame), and Reims. Architectural innovations—the pointed arch and the flying buttress—allowed the construction of soaring naves and walls pierced by large windows filled with the exquisite stained glass that was a great technological achievement of the period. And the taste for order is illustrated by the reorganization of masters, students, and studies as studia generalia (or universities). Montpellier became a leading centre of medical learning, and Toulouse (founded in 1229 to prepare clerics to combat heresy) and Orléans were noted for law. Paris remained preeminent among the early universities; its famous schools became associated as the faculties of arts, canon law, medicine, and theology, gaining jurisdictional independence under papal protection by 1231.

During the same years, philosophical doctrines in conflict with Christian orthodoxy began to trouble the theologians as translations of the metaphysical and scientific works of Aristotle and his commentators reached Paris. For a time the teaching of Aristotle was prohibited there, but by midcentury, when some of the “artists” who had been most attracted to the new philosophy were advancing to theological degrees, efforts were made to incorporate Aristotelian learning in enlarged summaries of Christian knowledge. The Summa theologiae (1266–72) by the Italian Thomas Aquinas was the greatest synthesis of this type. Its serene power breathes no hint of the controversies in which its author was involved. St. Thomas had taken his theological degree, together with St. Bonaventure, in 1257, when the secular masters were bitterly disputing the friars’ privileges within the university. In the end the Dominicans and Franciscans each retained a chair on condition of submitting to university regulations. Thomas’s work, however, came under suspicion. A reaction set in against the arts faculty’s increasing disposition to take a naturalistic view of all reality. When Étienne Tempier, the bishop of Paris, condemned some philosophical principles as “error” in 1270 and 1277, the repercussions were so sweeping as to render even Thomas suspect.

Thomas’s synthesis was to have no immediate imitators. Nevertheless, the social consequences of the emergence of academic learning in the 12th and 13th centuries were profound; it created new estates of professional men—lawyers, notaries, trained clerks, and physicians, many of them laymen—whose rational and legalist outlook became firmly rooted in French culture.

The dogmatic condemnations of the 1270s were symptomatic. Prosperity and confidence were shaken in many ways in the late 13th century. The papacy, hitherto a support for progressive causes, found itself discredited after its fiasco in a Crusade against Aragon. While the removal of the papal court to Avignon in the time of Clement V created a new centre of patronage for arts and letters, it did little to arrest the waning prestige of the church. The burdens of renewed warfare increased social tensions in the towns and depressed civic enterprise; the Jews had their assets confiscated before being expelled in 1306, and the Lombard bankers suffered like treatment in 1311. Economic indicators—while few and difficult to interpret—are generally held to suggest growing difficulties in many parts of France. The business of the fairs of Champagne was falling off by 1300, if not before, while records of Normandy reveal declining agrarian revenues in the half-century after 1260. Some regions were “saturated” with people: their existent economic technology could no longer sustain growth. Probably the population was already leveling off, if not yet decreasing, when, from 1315 to 1317, crop failures and famine caused serious disruption.
