Towne, Edgar A. "Toward More Clarity about Coherence in Whitehead's Metaphysics: A Proposal." Process Studies 38, no. 1 (Spring-Summer 2009): 69-92.

What I call ambiguities of system due to the sheer complexity of Whitehead's metaphysics and his analysis of process in terms of concrescence and transition threaten its coherence in terms of what we know empirically of the quantum and classical dimensions of nature. Ambiguities of equivocation pertaining to Whitehead's use of the terms "contemporary" and "objectification," as the latter is employed in relation to prehension and satisfaction, also threatens its coherence. The article proposes ways to reduce these threats and uncertainty about coherence by clarifying ambiguities and by attending to the way Whitehead's terms are predicated on the quantum and classical dimensions.
