This volume examines the scientific basis of reductionist approaches to understanding visual perception. The author makes the provocative argument that contemporary neuroscience and cognitive science have gone off on a wild-goose chase in the search for reductionist explanations of perceptual phenomena. This book considers some specific and general examples of this misdirection and suggests an alternative future course for science. It reviews the successes and failures of the sciences' efforts to explain perceptual and other mental functions in the terms of either internal cognitive mechanisms, formal models, or the neural structures from which the brain--the organ of the mind--is constructed. Although this is an iconoclastic and minority view, the book shows how many contemporary perceptual scientists have qualified their thinking with regard to what their data and theories mean even while generally accepting the empirical findings. It is, without question, an attempted refutation of some of the primary assumptions of contemporary theory. Summing up the author's convictions concerning some of the most important questions of human nature, this book is a statement of a point of view that has provided a framework for his personal answers to some of these important questions of human history.
