It has been about fifty years since the topic of divine impassibility was the subject of book-length philosophical treatments in English. In recent years process and analytic philosophers have returned this issue to the forefront of professional attention. Divine Impassibility traces the issue of classical sources, relates the positions of nineteenth- and early twentieth-century books, and surveys the writings of contemporary British analytic philosophers such as Peter Geach, Anthony Kenny, Richard Swinburne, John Hick, and H. P. Owen, American analytic philosophers such as Norman Kretzmann, Eleonore Stump, Nelson Pike, Robert Adams, and Bruce Reichenbach, and process philosophers such as Charles Hartshorne and Lewis Ford. The author shows that clear, adequate analysis of the issue must distinguish four respects in which God might be passible or impassible: nature, will, knowledge, and feeling. He shows also how decisions on this topic bear on numerous others in philosophical theology such as creation, eternality, evil, and human freedom. His creative proposals on these and other topics attempt to go beyond the difficulties of both classical and process conceptions of God.
