Medieval Supposition Theory Revisited

Editor: E.P. Bos
In 1962–1967 Professor L.M. de Rijk published his Logica Modernorum – A Contribution to the History of Early Terminist Logic. The first part (1962) has the title: On the Twelfth Century Theories of Fallacy. The second part (two volumes, 1967) has as title: The Origin and the Early Development of the Theory of Supposition. De Rijk’s Logica Modernorum provides the basis for the modern study of medieval theories of supposition.
Now, nearly 50 years later, scholars have made great progress in the study of the properties of terms. De Rijk’s study was primarily about the early development of terminist logic, i.e. during the 12th and 13th centuries. Scholars have also investigated later developments well into the sixteenth and seventeenth centuries. Not only logical texts, but also texts on grammar have been published. Many of the scholars who have contributed to this development, present papers in this volume.
Contributors are Fabrizio Amerini, Jenny Ashworth, Allan Bäck, Bert Bos, Julie Brumberg-Chaumont, Laurent Cesalli, Lambert Marie de Rijk, Sten Ebbesen, Alessandro Conti, Catarina Dutilh-Novaes, Onno Kneepkens, Costantino Marmo, Dafne Mure, Claude Panaccio, Ernesto Perini Santos, Joel Lonfat, Angel d’Ors, Göran Sundholm and Luisa Valente.
