Scholasticism was a school of philosophy of which historical period?

Scholasticism was a medieval school of philosophy that employed a critical method of philosophical analysis presupposed upon a Latin Catholic theistic curriculum which dominated teaching in the medieval universities in Europe from about 1100 to 1700. It originated within the Christian monastic schools that were the basis of the earliest European universities. The rise of scholasticism was closely associated with these schools that flourished in Italy, France, Spain and England.

Scholasticism is not so much a philosophy or a theology as a method of learning, as it places a strong emphasis on dialectical reasoning to extend knowledge by inference and to resolve contradictions. Scholastic thought is also known for rigorous conceptual analysis and the careful drawing of distinctions. In the classroom and in writing, it often takes the form of explicit disputation; a topic drawn from the tradition is broached in the form of a question, oppositional responses are given, a counterproposal is argued and oppositional arguments rebutted. Because of its emphasis on rigorous dialectical method, scholasticism was eventually applied to many other fields of study.

As a program, scholasticism began as an attempt at harmonization on the part of medieval Christian thinkers, to harmonize the various authorities of their own tradition, and to reconcile Christian theology with classical and late antiquity philosophy, especially that of Aristotle but also of Neoplatonism.
