Abstract

Whitehead conceived of God as an actual entity, but Hartshorne and Cobb treat God as a society of actual occasions.  On either view, God has a temporal consequent nature.  An actual entity is a temporal entity which concresces continuously, but in a society of actual occasions there is discontinuous concrescence.  Whitehead's "epochal theory of time" (which he did not apply to God) was a theory of discontinuous concrescence, according to which gaps exist between events during which nothing in that series exists at all.  In continuous concrescence there are no gaps, no discrete events.  It would be more in accord with our self-knowledge to regard our own stream of conscious experience and activity as like Gods in involving continuous concrescence, though differing from God's in other respects. I conclude with a short critique of the epochal theory of time.  [Abstract from The Philosopher’s Index]
