Abstract

Three conclusions can be drawn from the study of the word ratio and its derivatives in the works of Hugh of Saint-Victor. First, the approximately 1500 occurrences present an exceptional diversity of meanings. Second, these meanings are not tightly separated from each other, but tend to tile or merge: not only are there many passages where the translator can legitimately hesitate between two or more interpretations, but the author himself plays on this malleability of significations, as if to refer his reader to an original cohesion of the meanings. Third, it is therefore possible to reconstitute a complex but unified notion of reason, underlying all the uses identified; and it is surely no coincidence that this common notion corresponds very precisely to the Victorine educational program, as Hugh defined it in his Didascalicon.
