Chantal Jaquet offers a detailed analysis of time, duration and eternity from the early works of Spinoza to its eventual shape in the Ethics and Theologico-Political Treatise. She asks how it is possible for human beings, as finite modes of existence, to share in God's eternity, as well as how human existence relates to the eternity of God, or Nature. Jaquet situates Spinoza's thought in relation to the scholastic philosophies that preceded him, all with close attention to the Latin throughout. Chantal Jaquet is Professor of Philosophy at the University of Paris 1 Panthéon-Sorbonne. Eric Aldieri is Assistant Professor of Philosophy at Bridgewater State University.
