Leibniz on the Foundations of the Differential Calculus

Richard T. W. Arthur is Professor Emeritus at McMaster University, living in Toronto. Specializing in early modern natural philosophy, mathematics, and the foundations of physics, he focuses on time and the infinite. He holds degrees in physics (BA, Oxford, 1972) and philosophy (MA, McGill, 1976; PhD, Western Ontario, 1981). Arthur has taught applied mathematics and philosophy in Canada, Nigeria, the United States, and Italy. He has authored seven books and over 60 articles and chapters, primarily on seventeenth-century philosophy, including works on Leibniz, Newton, and Descartes. His notable books include "Leibniz" (Polity Press, 2014) and "Leibniz on Time, Space, and Relativity" (Oxford University Press, 2021). In philosophy of physics, he published "The Reality of Time Flow" (Springer, 2019). Currently, he is finishing four co-authored books, including studies on Leibniz's calculus, unpublished writings on the infinite, translations of Leibniz's scientific articles, and the influence of Leibniz on Bertrand Russell.

David Rabouin is a Senior Research Fellow (DR2) at the French National Centre for Scientific Research (CNRS), in the research group SPHERE (UMR 7219, CNRS - Université Paris Cité). His interest is in the history of philosophy and mathematics in the early modern period, with special focus on Descartes, Spinoza and Leibniz. He holds degrees in philosophy (PhD, Université Paris Sorbonne, 2002) and mathematics (MSc, Université Paris Diderot, 2014). He is currently the head of the ERC advanced grant PHILIUMM (Adg n°101020985): "The Philosophy of Leibniz in Light of His Unpublished Mathematical Manuscripts". He is the author of more than 100 articles and several books including Mathesis universalis. L'idée de « mathématique universelle » d'Aristote à Descartes (Paris, PUF, 2009), Spinoza. Ethique locale (Paris, P.U.F., 2010), with Norma B. Goethe and Philip Beeley G.W. Leibniz, Interrelations between Mathematics and Philosophy (Dordrecht, Springer, 2015), with the "Mathesis group", G. W. Leibniz. Mathesis universalis. Ecrits sur la mathématiques universelle (Paris, Vrin, 2018) and Mathématiques et Philosophie chez Leibniz. Au fil de l'analyse des notions et des vérités (Paris, Vrin, forthcoming).
