Ford, Lewis S.  “Prime Matter, Barrington Jones, and William Brenner.”  New Scholastcism 50, No. 2 (Spring 1976)

Though Whitehead compares creativity with prime matter, the only similarity between them is their formlessness, and the fact that neither can exist except in correlation with form. Richard Rorty has shown that post actual entities are the proper material causes for Whitehead.
