These volumes explore the roots and expressions of radical thought in medieval and Early Modern philosophy, highlighting both intellectual courage and intransigence across diverse traditions and institutional contexts.
Monica Brinzei is Senior Research Fellow (Directeur de recherche) at CNRS/IRHT and Vice-Director of IRHT. She was the PI of the ERC Starting-Grant THESIS (2012-2018) concerning lectures on the Sentences, and of the ERC Consolidator-Grant Debate (2018-2024) on the principia of Sentences lectures. She is currently the PI of the French consortium of RESTORY Horizon 2020 project (2024-2026). She is co-director of the Brepols series ‘Studia Sententiarum’ and in 2022, she was elected vice president of the SIEPM.
Irene Caiazzo is Senior Research Fellow at CNRS/LEM. Her research is focused on the history of medieval philosophy and science. She is editor-in-chief of the annual journal Archives d’histoire doctrinale et littéraire du Moyen Age. Her major publications include Lectures médiévales de Macrobe: Les Glosae Colonienses super Macrobium (Paris, 2002) and Thierry of Chartres: The Commentary on the De arithmetica of Boethius (Toronto, 2015).
Christophe Grellard is full professor (Directeur d'études) at Ecole Pratique des Hautes Etudes (PSL university) and a member of the Laboratoire d'études des monothéismes (LEM, CNRS). He has published extensively on the topics of medieval epistemology and moral philosophy. He is currently member of the Board of the SIEPM.
Aurélien Robert is Senior Research Fellow (Directeur de recherche) at the CNRS and Director of SPHERE research center (CNRS - Université Paris Cité - Université Paris 1). A specialist in the reception of ancient philosophy and science in the Middle Ages, he recently published Epicure aux enfers. Hérésie, athéisme et hédonisme au Moyen Âge (Paris, 2021), Le monde mathématique. Marco Trevisano et la philosophie dans la Venise du Trecento (Paris, 2023), as well as several edited volumes, including (with Ch. Grellard), Atomism in Late Medieval Philosophy and Theology (Leiden-Boston, 2009), (with J. Biard), La philosophie de Blaise de Parme. Physique, psychologie, éthique (Florence, 2019) and (with I. Caiazzo and C. Macris) Companion to the Reception of Pythagoras and Pythagoreanism in the Middle Ages and the Renaissance (Leiden-Boston, 2022)
These volumes present a selection of papers delivered in Paris at the XV International Congress of the Société Internationale pour l’Étude de la Philosophie Médiévale, August 22-26, 2022. The appearance of the term radix positionis in medieval debates inspired the contributors to investigate whether there was something that could be considered radical thought in the Middle Ages and, if so, what the roots of this radical thought were in the different philosophical traditions in various geographical, cultural, religious, and linguistic contexts (Arabic, Greek, Hebrew, Latin).
Medieval philosophy often engaged in a quest for origins, but it could also be radical in its methodology or in its attitude when it refused any compromise on its principles or basic concepts, be they innovative or rediscovered. Radicalism could be conceived as extremism in pushing a hypothesis, procedure, or line of inquiry to its limits, leading to extreme positions. Radical thought could mean being intellectually inflexible on principles, obstinate in embracing theses that broke from tradition, progressive but also extremist. The contributions in these volumes thus analyse case-studies of doctrinal conflict, dogmatic struggle, and condemnation by religious or academic institutions, presenting examples of both intellectual courage and philosophical intransigence.
