For the new edition, Loptson has addressed the new developments in the rapidly expanding genetic and paleontological record, as well as expanded the discussion of the Christian theory of human nature by incorporating the ideas of the Marx scholar and social theorist G.A. Cohen. The new edition has also been substantively revised and updated throughout.
Peter Loptson is Professor of Philosophy at the University of Guelph and also the author of Reality: Fundamental Topics in Metaphysics (University of Toronto Press, 2001).
