This book provides a novel introduction both to human intelligence and to artificial intelligence. It discusses the underlying mechanisms by which intelligent behavior is achieved, how these mechanisms have evolved, and how they operate. The authors emphasize the central role of "representation," the use of internal models, as the major mechanism underlying intelligent behavior. This important and fascinating book combines general philosophical themes with detailed technical information. While the authors have attempted to make the text understandable to an educated layman, they have also provided ample material of more interest to the specialist. Ideal for a less technical introduction to AI. 0201120011B04062001
