Abstract

Many interpret the final vision of God in Whitehead's "Process and Reality" as already largely anticipated in his earlier book.  Compositional analysis reveals, however, that there are two layers of insertions portraying two distinct, unanticipated conceptions of God.  The final layer presents the familiar God of process theism.  The other layer portrays "the primordial actuality" as purely nontemporal but concrescent.  If we put these insertions to one side, the original text of "Process and Reality" (over 200 pages) mentions God only as nontemporal and nonconcrescent.  What led to this apparent impoverishment?  Why did Whitehead draw back from the magnificent portrayal he had just proclaimed?  [Abstract from The Philosopher's Index]
