Medieval Mereology

Andrew Arlig

Pages 338 - 345

The ultimate source of many key medieval mereological principles was Aristotle (see especially, Metaphysics V, 25-27, and Historia Animalium I, 1). The proximate sources for most medieval discussions of mereology in the Latin West were the logical handbooks of Boethius, in particular, his De divisione and his textbooks on the “topics” (loci). In the Thirteenth and Fourteenth centuries, Boethius’s framework was supplemented both by the newly recovered writings of Aristotle and by the Latin translations of Arabic philosophical works.
