From the carolingean period, one may note the gradually increasing presence of dialectic in the latin philosophical scenario. The question that arises to those thinkers, specially on the 10th and 11th centuries, concerns the relation between the study of the Sacred Scriptures and dialectic. Anselm of Canterbury represents an important moment on the dissolution of this tension, even writing an entirely dialectic work, De grammatico. The "originality" of his thinking gains proportions when compared to the hierarchical solution of his contemporary, Peter Damian, or when we turn attention to the dispute on the eucharist, in which Lanfrac is seen by the tradition as a defensor of the prominence of faith, and Berengar proclaimed as defensor of dialectic. This thesis investigates the theoretical shifts that allow Anselm to propose a different solution to the problem of dialectic in theology.
