““The earliest medieval logical curriculum, studied from the time of Alcuin’s On Dialectic (late 780s?) until the late tenth century, was based mainly on the accounts of logic in the encyclopedias of Cassiodorus, Isidore of Seville and Martianus Capella, together with Apuleius’s Periermenias (an account of basic Aristotelian syllogistic) and the Ten Categories, a paraphrase-commentary of Aristotle’s Categories. The last of these was written in the circle of Themistius, but attributed in the Middle Ages to Augustine. This misattribution points to one of the reasons why logic had such a large place in early medieval education: it was seen as indispensable in theological discussion, both because it provided a way of posing fundamental questions about God and his relation to his creation, and because it furnished a formidable argumentative weapon in controversy.””
