Abstract

In this model critical edition, Professor John Magee of the University of Toronto has provided specialists in the philosophy of the Middle Ages with one of the classical texts of their period, Boethius’s De divisione. Surviving in over seventy manuscripts, and practically required reading both in monastic schools and universities, Boethius’s De divisione treats the modes of division commonly discussed in ancient philosophy: the per se divisions of genera into species, a whole into its parts, and a spoken sound into its significates; the accidental divisions of a subject into its accidents; an accident into its subject, and accidents into other accidents. With its clear examples and carefully argued rationale for the manner of dividing and defining, the work remained a canonical text to the end of the Middle Ages when Aristotelian learning declined in importance.
