Mereology in Medieval Logic and Metaphysics

The term ‘mereology’ was coined by the twentieth-century Polish logician Stanisław Leśniewski to indicate the logic of the part-whole relation. During the Middle Ages no philosopher develops a full-fledged mereological theory, nonetheless many philosophers and theologians reflect on the notions of part and whole and their relation, from very different perspectives. Discussions especially concern logic and metaphysics, but they also have important implications for theology. The present volume recollects twelve essays that originally contribute to the studies on medieval mereology from Antiquity to the end of the fourteenth century.
