If there was a single event that changed education and scholarship in the late Middle Ages, it was the arrival of the lost works of the ancient Greek philosopher Aristotle. Aristotle was one of the greatest geniuses of the ancient world, producing learned works on philosophy, astronomy, physics, biology, literary criticism and, most importantly for medieval Europe, logic. Some of Aristotle's works had survived in Europe after the fall of Rome, but most of it had vanished. Over the course of the eleventh century, translations of Aristotle's work on formal philosophical logic re-emerged in Europe. Most had been preserved in the Arab world, where Aristotle was considered the single most important pre-Islamic philosopher and was studied with great rigor by Arab scholars. Enterprising scholars - many of them Jewish philosophers who lived in North Africa and Spain - translated Aristotle's work on logic from Arabic into Latin. Later, Greeks from Byzantium came to Europe with the originals in Greek and they, too, translated it into Latin.
The importance of this rediscovery of Aristotle is that his work on logic offered a formal system for evaluating complicated bodies of work like the Christian Bible itself. The inherent problem facing believers of any religion based on a single major text is figuring out what that text fundamentally means. To wit: the Christian Bible is full of parables, stories, and accounts of events that are often terrifically difficult to interpret. Even in the four gospels that describe the life of Christ, not all of Christ's actions or sayings are easy to understand, and the gospels sometimes offer conflicting accounts. What did Christ mean when he said "Again I tell you, it is easier for a camel to go through the eye of a needle than for someone who is rich to enter the kingdom of God" (Matthew 19:24)? What did he mean with "Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword" (Matthew 10:34)? Not to mention, how was a Christian to make sense of the stern, vengeful God described in the Old Testament and the deity of peace and forgiveness represented by Christ? Most medieval Christians were content to simply accept the sacraments and offer prayers to the saints without worrying about the theological details, but increasingly, educated priests themselves wanted to understand the nuances of their own religion.
Thus, Aristotle’s formal approach to logic proved invaluable to the interpreters of the Bible. Armed with his newly-rediscovered system of logical interpretation, key figures within the Church began to analyze the Bible and the works of early Christian thinkers with new energy and focus. The result was scholasticism, which was the major intellectual movement of the High Middle Ages. Scholasticism was the rigorous application of methods of logic, originally developed by Aristotle, to Christian scriptures. And, because the cathedral schools of the late Middle Ages increasingly relied on scholasticism to train and teach new priests, it spread rapidly across all of Europe.
By roughly 1100 CE, a new form of formal education based on scholasticism was the method of instruction in cathedral schools. The instructor would read a short passage from the Bible or an early Christian intellectual leader, then cite various authorities on the meaning of the passage. This was called the lecture, which simply means the "reading." Students would then consider the possible meanings of the passage in a period of meditation. Finally, students might be called on to debate their respective interpretations. In debates, students were expected to cite not only the passage itself but any supporting evidence they could come up with from the vast body of sacred and ancient writings. The result was that, at least at the better cathedral schools, large numbers of newly-minted priests emerged with a strong understanding of Christian thought and an equally strong grasp of rhetoric, debate, and logic.
Some teachers in the scholastic tradition became minor intellectual celebrities, the most celebrated being Peter Abelard (1079 – 1142), a brilliant teacher and debater in Paris who gave extensive lectures exploring both the pros and cons of various important questions that had been considered by the Church fathers. Abelard’s major focus was the use and application of reason to faith – he was of the belief that ultimate truth could and should sustain reasoned investigation of its precepts, a stance that got him into considerable trouble with some Church leaders. Abelard's point was that educated Christians should challenge their own beliefs and try to understand them; to him, since Christians were safe in the assumption that the Bible would always be the ultimate source of truth, their own attempts to understand its apparent contradictions and ambiguities only strengthened the Christian religion as a whole.
The new rigor of education and the expansion of cathedral schools, helped in part by the popularity of figures like Abelard, led in turn to the emergence of the first true universities. Initially, they were comparable to craft guilds, with organizations of students and teachers negotiating over the cost of classes and preventing unauthorized lecturers from stealing students. A princely charter was granted to the law students of Bologna in northern Italy in 1158, which marks it as the first recognized university. The most significant medieval university was, however, the Sorbonne of Paris in 1257. It grew out of the cathedral school of Notre Dame, at which Abelard had taught, and it is usually considered the oldest large university in the western world (it is still very much in operation today).
Medieval universities created a number of practices that live on to the present in higher education. They drew up a curriculum, established graduation requirements and exams, and conferred degrees. The robes and distinctive hats of graduation ceremonies are directly descended from the medieval models. Teachers were all members of the clergy, “professing” religion, hence the term "professor." The core disciplines, which date back to Roman times, were divided between the liberal arts of grammar, rhetoric, and logic (called the trivium) and what might now be described as a more “technical” set of disciplines: arithmetic, geometry, astronomy, and music (the quadrivium) - this division was the earliest version of a curriculum of “arts and sciences.” Finally, the four kinds of doctorates, the PhD (doctor of philosophy), the JD (doctor of jurisprudence, that is to say of law), the ThD (doctor of theology, a priest), and the MD (doctor of medicine), are all derived from medieval degrees.
All students and professors were male, since the assumption was that the whole purpose of studies was to create better church officials; while some women did become outstanding medieval thinkers, they were either exceptional individuals who had been tutored by men or were nuns who had access to the (often excellent) education of the convents.
