"Contemporary Debates in Metaphysics" features original essays on some of the most hotly debated issues in the field. Is personal identity psychological or physical? Do abstract entities such as universals, propositions, and numbers actually exist? Are determinism and freedom incompatible? Nine pairs of newly commissioned essays face off on opposite sides of fundamental problems in current questions in metaphysics. This distinctive format offers readers a unique opportunity to observe philosophers engaging in head-to-head debate. An introductory essay written by the editors will situate the reader by emphasizing the recurring theme in metaphysics of reductionism versus primitivism. Showcasing clear and concise statements of sophisticated philosophical views, this volume is an excellent resource for professional philosophers and students alike.
