Grounding in Medieval Philosophy

This book offers a selection of 13 case studies on how the notion of grounding helps illuminate philosophical discussions of our past with a special focus on debates of the Middle Ages. It thereby makes not only the case that the notion of grounding, which has become so widely debated in analytic metaphysics, has a long and venerable tradition, but also shows that this tradition has a lot to teach to contemporary philosophers of grounding. This is because the historical authors discussed in this volume – that is, Aristotle, Fazang, Boethius, Avicenna, Abelard, Aquinas, Scotus, Ockham, Buridan, Suárez, Leibniz, and others – suggested different types of non-efficient-causal explanations which are to be carefully distinguished. This volume illustrates how philosophy and history of philosophy can be mutually illuminating by showing that the terminology developed in the contemporary debate about grounding can help reconstruct philosophical discussions from Antiquity up to the Early Modern Period, and that these very discussions enrich, and in part challenge the contemporary debate about grounding. In this vein, it is an important reading for everyone interested in the history of grounding and the philosophical insights that this history might have left to us.
