Gerbert of Aurillac (938–1003)

Gerbert is chiefly remembered as an educational reformer. He established a syllabus for the university course in logic, the logica vetus, that remained in use until the mid-twelfth century. Most of his academic writings are instructional works on mathematics. In his single philosophical work, De rationali et ratione uti (On That Which is Rational and Using Reason), he uses Boethius’ logical commentaries to develop a distinctly Platonic solution to a problem he derives from Porphyry’s Isagōgē.
