Common Methods

One of the principal methods of Scholasticism was the use of the logic and philosophic vocabulary of Aristotle in teaching, demonstration, and discussion. Another important method was the practice of teaching a text by means of a commentary by some accepted authority. In philosophy, this authority was usually Aristotle. In theology, the principal texts were the Bible and the Sententiarum Libri Quatuor (Four Books of Sentences) by the 12th-century Italian theologian and prelate Peter Lombard, a collection of the opinions of the early Fathers of the Church on problems of theology. The early Scholastics began by adhering closely to the text on which they were commenting. Gradually, as the practice of critical reading developed their own powers of thinking, they began to introduce many supplementary commentaries on points, known as disputed questions, which either were not covered or were not adequately solved by the text itself. Beginning in the 13th century these supplementary commentaries, embodying the personal thought of the teachers, became the largest and most important part of the commentaries, with the result that literal explanation of the text was reduced to a mere fraction of each commentary.

Closely allied with the commentaries on disputed questions was the technique of discussion by means of public disputation. Every professor in a medieval university was required to appear several times a year before the assembled faculty and students in a disputation, defending crucial points of his own teaching against all persons who challenged them. The forms of Aristotelian logic were employed in both defense and attack. In the 13th century the public disputation became a flexible educational tool for stimulating, testing, and communicating the progress of thought in philosophy and theology. After the middle of the 14th century, however, the vitality of public disputation declined, and it became a rigid formalism. Disputants became concerned less with real content and more with fine points of logic and minute subtleties of thought. This degraded form of disputation did much to give Scholasticism a bad reputation during the Renaissance and later; consequently, many modern thinkers have considered it mere pedantic logical formalism.
