Abstract

Norris Clark SJ and Robert Neville have argued that a coherent Whiteheadian theism/metaphysics requires a better theory of unity than the one Whitehead himself espouses, namely one founded on creativity itself (category of the ultimate).  They argue that unity must be ultimately grounded in the creative act of God who creates the world "ex nihilo".  But, such a doctrine of creation is wedded to the doctrine of eternity.  The doctrine of eternity, in turn, makes superfluous time as qualitative increase in the universe.  Eternity, therefore, destroys the central thesis of Whitehead's philosophy -- creativity.  Only a dialectical theory of unity in which both God and world are mutually required can serve to bring coherence to Whiteheadian metaphysics.  Lewis Ford, in part, points the way by his theory of God as the future of all actual occasions.  [Abstract from The Philosopher's Index]
