Marshall McLuhan on the History of the Trivium

…the history of the trivium is largely a history of the rivalry among them for ascendancy.  Ancient grammar was at odds with the dialectics of Plato and, especially, of Aristotle, as the art of interpreting phenomena.  As the method of patristic theology, grammar enjoyed uninterrupted ascendancy until the revival of dialectics by Gerbert, Roscellinus, and Abelard in the eleventh and twelfth centuries.  With the decadence of dialectical or scholastic theology in the fourteenth and fifteenth centuries both grammarians and rhetoricians surge forward again, finally triumphing in the work and influence of Erasmus, the restorer of patristic theology and of the grammatical humanistic discipline on which it rests.  On the other hand, the war between the dialecticians and rhetoricians began as soon as the Sophists attempted to make dialectics subordinate to the art of persuasion.  Plato and Aristotle were the greatest enemies of the rhetoricians, not so much in rejecting rhetoric, as in asserting that as an art it had no power to control dialectics.  The Stoics, however, are the main defenders of dialectics against rhetoric after Aristotle.

A point which will be focused on in the present unnamed Lyceum trivium project (being constituted by a series of lectures and discussion sessions which will result either in a video, text, or other public-facing production: see more on our approach to the Trivium here), the conflict of “ascendancy” among the arts of the trivium is a subtle point to which few have drawn attention as well as McLuhan. One difficulty I see emergent from the history of their rivalry is a certain blindness to their unity. What makes something one? An indication hinted at here—whether intentionally or not—is the point of “decadence” in the fourteenth and fifteenth centuries among the scholastics. This decadence itself is a point in need of exploration and exposition, for, certainly, while those under the influence of Ockham and other nominalistic theories were undoubtedly decadent in their dialectical practice, given that they had abandoned the essential principle of unity between thought and things, it is also true that other scholastics were not so decadent, though they may have been quite elaborate in their use of dialectic nonetheless. (See, for instance, the great work being done on the thought of the Conimbricenses.)

The opposition of grammar, dialectics, and rhetoric, that is, has never rendered robust intellectual fruit when one attempts entirely the suppression of the others. Each must be understood as an integral part of a whole. What remains a question—which we will explore explicitly in the second of our lectures and discussions—is how these parts are united and oriented as a whole. This question requires also, antecedently, a consideration of what the trivium aims at; for every unity is governed, in some way or another, by the end for the sake of which it exists. This question was the focus of our first session, wherein it was discussed that the arts of the trivium, as tools of reflection upon thought, are tools whereby we manifest in language what is true. This truth is not merely factual (i.e., of the literal and measurable), but revelatory of being.

And so the question becomes: through which of the arts do we best orient ourselves towards what is true, without leaving behind the others?
