Abstract

Perhaps more than any other aspect of his thought, Alfred North Whitehead’s rejection of the notion of “independent existence” or substance has been taken to define his philosophy of organism. Moreover, it is this rejection of substances which has been the source of some of the most significant objections to Whitehead’s thought. Many commentators often indicate sympathy with Whitehead’s project but ask, if the world is composed exclusively of microscopic events which neither endure nor have histories, then how can Whitehead account for enduring, macroscopic individuals such as ourselves? That is, having rejected the notion of unchanging subjects of change, how can Whitehead’s account adequately capture the unity and self-identity of macroscopic individuals? The contemporary Neo-Thomist W. Norris Clarke gives voice to this potentially damaging objection. A close analysis of aspects of Clarke’s work will prove rewarding in several respects. Not only does Clarke provide a clear challenge to a non-substantial model of individuality by explicitly formulating and defending the objection that Whitehead’s system only allows for an attenuated conception of macroscopic individuality, Clarke’s own dynamic interpretation of the classical notion of substance seriously calls into question the very need for Whitehead’s “process turn” toward what Clarke sees as a misguided metaphysical atomism. Thus, engaging Clarke’s objection provides a valuable opportunity not only to evaluate the adequacy of his dynamic notion of substance, but also to respond to the common criticism that Whitehead’s system does not do justice to the unity of macroscopic individuals.
