François Zourabichvili was a director at the Collège international de philosophie in Paris from 1998 to 2004. He is the author of Deleuze: A Philosophy of the Event (Edinburgh University Press, 2012) and Spinoza: Une physique de la pensée (Presses Universitaires de Paris, 2002) Eric Aldieri is Assistant Professor of Philosophy at Bridgewater State University. He has been published in Hypatia, Deleuze & Guattari Studies, and Derrida Today and The Journal of Speculative Philosophy. He has translated several works of French Spinozism into English, including Chantal Jaquet’s Time, Duration, and Eternity in Spinoza, published by Edinburgh University Press in 2023. His co-authored translation of François Zourabichvili’s Spinoza, A Physics of Thought: Form and Individuation will publish in March 2026, also with Edinburgh University Press. Gil Morejón teaches at Loyola University Chicago. His research focuses on early modern metaphysics and political theory. He is the author of The Unconscious of Thought in Leibniz, Spinoza and Hume (Edinburgh University Press, 2022) and co-edited and co-translated Alexandre Matheron's Politics, Ontology and Knowledge in Spinoza (Edinburgh University Press, 2020).

Many have turned to Spinoza for a theory of the body, restoring affects and desire to a philosophical tradition burdened by idealism. Zourabichvili demonstrates that Spinoza is also a thinker of the mind, of the production, generation, and transformation of ideas. A fundamental contribution to Spinoza scholarship and contemporary philosophy.
