Abstract

George Molnar died before finishing his book. He did not write a first chapter, and planned applications of his theory were left in an incomplete state. Nevertheless, what we do have makes this volume one of the important works of metaphysics to appear in recent years. A great debt of gratitude is owed to Stephen Mumford. He has written an excellent substitute for Molnar’s introductory chapter, and given an impressive amount of order to the concluding material.
