Abstract

How, in Whitehead's philosophy, does God influence the world?  Hartshorne proposes we modify Whitehead's position by conceiving of God as a series of momentary divine occasions.  Then God influences the world the same way regular actualities do, by the past affecting the present.  I propose instead that God be conceived as an activity located in those spatiotemporal regions which are future to us.  That activity is now in unison of becoming with us, but when those regions become present, God's activity is pluralized into the individual activities of present occasions.  God's prehensive activity unifies the past in every way it can be, while the individual occasion decides which of these real possibilities will be determinately actualized.  [Abstract from The Philosopher's Index]
