Synopsis
Traces the development of scientific and psychological theories of human perception and consciousness and shows their significance in relation to such enduring questions as the nature of reality and of humanity
Reviews
How human perception works is a mystery that science has scarcely begun to unriddle, observes Bolles ( So Much to Say! ). Perception, as he defines it, is a creative faculty by which we keep ourselves oriented, evaluate experience and pick out meaningful qualities from the sensory deluge. Behaviorism "tried to bluff its way through" this puzzle, while computer-based models of perception--for example, neural nets to imitate the brain's actual circuitry--"come up short," in Bolles's judgment. Interjecting his personal experiences, he takes readers on a conversational tour through the maze of perception, throwing fresh light on visualization, optical illusions, theories of dreaming, color vision, cultural differences in perception and the pervasive roles of pleasure, pain, emotion and awareness in determining how we perceive and construct reality.

In spite of the New Age-ish title, the latest from Bolles (Remembering and Forgetting, 1987, etc.) attempts to put perception in proper perspective--not as a mystical phenomenon, but at the very heart of how we comprehend ourselves and the world. On the other hand, don't expect to come away with a clear idea of what perception is. Bolles is rather better at saying what it is not. So he starts off with a visit to the artificial-intelligence folks who are trying to get computers to recognize (perceive) speech and language. Not much new to report here: The machines do well by learning a particular speaker's idiosyncracies--but they can't seem to generalize. Then Bolles goes on to review what happened in psychology in the 20th century with the rise of both behaviorism and Freudianism--widely divergent schools of psychology that nevertheless share what Bolles calls a ``physicalist'' point of view that there is an objective world out there. He offers a nice discussion of Gestalt psychology, but faults that school for its naive realism. What Bolles touts instead is the brain's imparting meaning to sensations, constructing perception by analyzing neural inputs that change over time as a result of learning, attention, emotion. If this sounds nebulous, it is. If this sounds as if there's still a question of the ghost in the machine (who is aware and waiting and watching), there is. As for enlightening the reader on what is current and choice about neural coding (for pain, for example), forget it. Bolles is more concerned with putting perception on a pedestal than in telling us what it's all about. (Nine line drawings.) -- Copyright ©1991, Kirkus Associates, LP. All rights reserved.
This is an interesting account of theories about the nature of human perception, conflicts between those who account for everything in purely physical terms, and the humanists who emphasize mystery. The book also reveals the relationship between perception and meaning, and discusses everyday perceptions such as dreams, thoughts, and sensations. Bolles consistently emphasizes the role of awareness and the importance of acknowledging mystery as he explores issues concerning human consciousness, human uniqueness, and the contributions of culture to perception. His book is recommended especially for public and seminary libraries.
