This book offers a collection of contributions on medieval, early modern, and contemporary perspectives on social ontology.  Since the 1990s, social ontology has emerged as a vibrant research area in contemporary analytical philosophy. Questions concerning the nature and properties of social groups, institutions, facts, and objects like money and marriage, have been thoroughly discussed. However, the historical perspective has been largely neglected. One of the central aims of this volume is to show that relevant views on social ontology can be found in medieval and early modern philosophy (ca. 1200-1700 C.E.), when, for example, the ontological status of money, law, and the sacraments was hotly debated. We see, furthermore, diverging positions between Aristotelian-inspired authors, who resort to a more naturalistic view of the emergence of the social realm, and authors like Olivi and Ockham, who emphasize the role of human free will and contractualist agreements.  This book is the very first to address historical and contemporary social ontologies. Both historians of philosophy and philosophers will benefit from this juxtaposition, which fosters a better understanding of historical positions and approaches by using today’s conceptual and analytical tools, and allows the contemporary debate to gain new perspectives by confronting its own medieval and early modern history.

This edited volume presents new lines of research dealing with the language of thought and its philosophical implications in the time of Ockham. It features more than 20 essays that also serve as a tribute to the ground-breaking work of a leading expert in late medieval philosophy: Claude Panaccio. Coverage addresses topics in the philosophy of mind and cognition (externalism, mental causation, resemblance, habits, sensory awareness, the psychology, illusion, representationalism), concepts (universal, transcendental, identity, syncategorematic), logic and language (definitions, syllogisms, modality, supposition, obligationes, etc.), action theory (belief, will, action), and more. A distinctive feature of this work is that it brings together contributions in both French and English, the two major research languages today on the main theme in question. It unites the most renowned specialists in the field as well as many of Claude Panaccio's former students who have engaged with his work over the years. In furthering this dialogue, the essays render key topics in fourteenth-century thought accessible to the contemporary philosophical community without being anachronistic or insensitive to the particularities of the medieval context. As a result, this book will appeal to a general population of philosophers and historians of philosophy with an interest in logic, philosophy of language, philosophy of mind, and metaphysics.
