Perler, D. Essentialism and Direct Realism: Some Late Medieval Perspectives. Topoi 19, 111–122 (2000).

This book is a major contribution to the history of philosophy in the later medieval period (1250-1350). It focuses on cognitive theory, a subject of intense investigation during these years. In fact many of the issues that dominate philosophy of mind and epistemology today - intentionality, mental representation, scepticism, realism - were hotly debated in the later medieval period. The book offers a careful analysis of these debates, primarily through the work of Thomas Aquinas, John Olivi, and William Ockham. Each (...) of these figures attempts to reconceptualise cognition along direct realist lines, criticising in the process the standard Aristotelian account. Though of primary interest to medieval philosophers, the book presupposes no background knowledge of the medieval period, and will therefore interest a broader community of philosophers concerned with the origins of contemporary cognitive theory.

Robert Pasnau’s paper presents a strong thesis, which it does not manage to substantiate. The thesis in question is that the Aristotelian doctrine of the identity of the knower and the known, as interpreted by St. Thomas, cannot possibly be used to fend off skepticism.

Die Intentionalitätsproblematik steht nicht nur im Mittelpunkt der heutigen philosophischen und kognitionstheoretischen Debatten. Sie wurde bereits im Mittelalter scharfsinnig diskutiert, ja die scholastischen Autoren prägten als Erste die Fachausdrücke "Intentionalität" und "intentionale Existenz" und entwarfen verschiedene Modelle, um das Rätsel der kognitiven Bezugnahme zu lösen. Dieses Buch stellt fünf einflußreiche Intentionalitätsmodelle vor, die im 13. und 14. Jahrhundert entstanden sind. Dabei werden so unterschiedliche Autoren wie Thomas von Aquin, Petrus Johannes Olivi, Dietrich von Freiberg, Johannes Duns Scotus, Petrus Aureoli, Hervaeus (...) Natalis, Wilhelm von Ockham und Adam Wodeham berücksichtigt. -/- "Die anschauliche und präzise Art, in der Perler mit den Denkern des Mittelalters und der Gegenwart argumentierend spricht, lockert seine gestrenge Gedankenarbeit auf, ohne darüber hinwegzutäuschen, daß dieses Buch eine Reihe von Entdeckungen und Klärungen enthält, wie sie auf diesem schwierigen Feld selten vorkommen. Er bietet eine Meisterleistung an Konzentration und Darstellungskunst. Wenige Bücher zur Philosophie des Mittelalters vereinen so glücklich wie dieses geschichtlichen Takt und Problemsinn." Kurt Flasch -/- The problem of intentionality is not only at the centre of today's philosophical and cognitive theory debates. It was already discussed astutely in the Middle Ages; indeed the scholastic authors were the first to coin the technical terms "intentionality" and "intentional existence" and designed various models to solve the riddle of cognitive reference. This book presents five influential models of intentionality that emerged in the 13th and 14th centuries. It takes into account authors as different as Thomas Aquinas, Petrus Johannes Olivi, Dietrich von Freiberg, Johannes Duns Scotus, Petrus Aureoli, Hervaeus Natalis, Wilhelm von Ockham and Adam Wodeham. Upun reading this book, Kurt Flasch remarks that it "contains a wealth of discoveries and clarifications that are rare in this difficult field. [Perler] offers a masterly performance of concentration and art of representation [...]. Few books on medieval philosophy succeed so thoroughly in uniting historical and philosophical perspicacity such as this one". (shrink)
