Abstract

A defense of Whitehead's development of God against the criticism that his treatment leads to incoherence.  The so-called incoherencies are the categoreal results entailed by an entity concrescing according to a reversed polar structure.  This reversal is occasioned by the metaphysical requirement that novelty be grounded in actuality.  Only an everlasting entity originating in the mental pole, such as Whitehead describes in part v of Process and Reality, coherently satisfies this requirement.  [Abstract from The Philosopher’s Index]
