Already the subject of considerable pre-publication discussion, this magisterial work by one of the nation's leading neuroscientists presents a radically new view of the function of the brain and nervous system. Its central idea is that the nervous system in each individual operates as a selective system resembling natural selection in evolution, but operating by different mechanisms. By providing a fundamental neural basis for categorization of the things of this world it unifies perception, action, and learning. The theory also completely revises our view of memory, which it considers to be a dynamic process of recategorization rather than a replicative store of attributes. This has deep implications for the interpretation of various psychological states from attention to dreaming. Neural Darwinism ranges over many disciplines, focusing on key problems in developmental and evolutionary biology, anatomy, physiology, ethology, and psychology. This book should therefore prove indispensable to advanced undergraduate and graduate students in these fields, to students of medicine, and to those in the social sciences concerned with the relation of behavior to biology. Beyond that, this far-ranging theory of brain function is bound to stimulate renewed discussions of such philosophical issues as the mind-body problem, the origins of knowledge, and the perceptual basis of language.

A neuroscientist demystifies the subject of consciousness in this up-to-date discussion of mind-body connections. How does the firing of neurons give rise to subjective sensations, thoughts, and emotions? How can the disparate domains of mind and body be reconciled? The quest for a scientifically based understanding of consciousness has attracted study and speculation across the ages. In this direct and non-technical discussion of consciousness, Dr. Gerald M. Edelman draws on a lifetime of scientific inquiry into the workings of the brain to formulate answers to the mind-body questions that intrigue every thinking person. Concise and understandable, the book explains pertinent findings of modern neuroscience and describes how consciousness arises in complex brains. Edelman explores the relation of consciousness to causation, to evolution, to the development of the self, and to the origins of feelings, learning, and memory. His analysis of the brain activities underlying consciousness is based on recent remarkable advances in biochemistry, immunology, medical imaging, neuroscience, and evolutionary biology, yet the implications of his book extend farther--beyond the worlds of science and medicine into virtually every area of human inquiry.
