Mind, Body, and Morality consists of fifteen chapters written by scholars who have contributed significantly to the new turn in Descartes and Spinoza scholarship. The volume is divided into three parts. The first group of chapters examines different metaphysical and epistemological problems raised by the Cartesian mind-body union. Part II investigates Descartes’ and Spinoza’s understanding of the relations between ideas, knowledge, and reality. Special emphasis is put on Spinoza’s conception of the relation between activity and passivity. Finally, the last part explores different aspects of Descartes’ moral philosophy, connecting his views to important predecessors, Augustine and Abelard, and comparing them to Spinoza.
