Abstract
Histories of philosophy frequently depict the later eleventh century as the scene of a series of bouts between dialecticians and anti-dialecticians — Berengar vs. Lanfranc, Roscelin vs. Anselm — preliminaries to the twelfth century welterweight contest between Abelard and St. Bernard and — dare one say? — the thirteenth century heavy-weight championship between St. Thomas and St. Bonaventure.The bouts took place — no question about that — but whether the contestants can properly be characterized as dialecticians and anti-dialecticians is less certain. Dialectics is logic, the third part of the trivium, and increasingly cultivated in the eleventh century; men like Berengar and Roscelin were plainly eager to apply the logical tools with which they had been equipped to the solution of intellectual problems. In particular they undertook the solution of certain central problems of theology — Berengar that of the Eucharist and Roscelin that of the Trinity — and it was this, we are told, that aroused the ire of the anti-dialecticians: if the aim of the dialecticians was to lay bare the mysteries of faith to the light of reason that of the anti-dialecticians was to protect those same mysteries from profanation.
