Abstract
The bulk of this work is a responsible and well documented exposition of Whitehead's major themes with emphasis on how they contribute to his theory of perception and how his developing theory of perception contributes to them. Although Schmidt divides Whitehead's development into three parts, the important part of the project, and obviously his favorite, is the elucidation of Whitehead's "mature theory of perception" and the demonstration that it provides a foundation for the cosmological system and his philosophy of science. Throughout, Whitehead is presented as an empiricist, although not in the usual sense. Perception and immediate experience are his starting point, but "perception" is used in a more basic, generic sense than is customary. It includes conception as well as sense-presentation. Schmidt pays prolonged and welcome attention to presentational immediacy, causal efficacy, and symbolic reference. The book contains some useful expansions of underdeveloped Whiteheadian doctrines, elucidations of Whiteheadian obscurities, and a number of interpretive distinctions, all of which serve to make it a useful new commentary as well as a proposal of an important thesis.--S.
