Abstract

A response to Robert H. Kimball's charge that A. N. Whitehead's account of perception is incoherent.  Kimball argued that Whitehead's account failed to reconcile two traditional theories of perception: phenomenological (sense-data) theory and causal (physiological) theory.  Kimball's charge results from a misguided attempt to place Whitehead's theory within the parameters of a debate between two traditional theories.  Instead, Whitehead supersedes that debate by offering a more comprehensive picture.  [Abstract from The Philosopher's Index]
