Abstract

Where is God?  Projecting from Whitehead's mathematical concept of interpoints, God and the world occupy a "similarity of position," but God is not a member of the world since he intersects all its realities simultaneously.  (The relational model is a complex point derived from linear objective reals of vector character).  Because their locations overlap, there can be no empirical evidence of God's presence according to logic allied with Euclidean concepts of the identity of things in space.  But relativity physics collapses the logical criteria for verifying location in spacetime; new criteria are needed which allow access to plenitude and simultaneity.  [Abstract from The Philosopher’s Index]
