Since 1977, Hofstadter, the author of Godel, Escher, Bach, and his students have been developing computer models of discovery, creation, and analogical thought. What has emerged is a sophisticated and unorthodox vision of the mind in which perception, at an abstract level, is the key: perception of situations, of patterns, of patterns among patterns. This book conveys this bold vision to a broad public.

Illustrations. nReaders of earlier works by Douglas Hofstadter will find this book a natural extension of his style and his ideas about creativity and analogy; in addition, psychologists, philosophers, and artificial-intelligence researchers will find in this elaborate web of ingenious ideas a deep and challenging new view of mind.
