Summary

Pamela McCorduck first went among the artificial intelligentsia when the field was fresh and new, and asked the scientists engaged in it what they were doing and why. She saw artificial intelligence as the scientific apotheosis of one of the most enduring, glorious, often amusing, and sometimes alarming, traditions of human culture: the endless fascination with artifacts that think. Machines Who Think was translated into many languages, became an international cult classic, and stayed in print for nearly twenty years. Now, Machines Who Think is back, along with an extended addition that brings the field up to date in the last quarter century, including its scientific and its public faces. McCorduck shows how, from a slightly dubious fringe science, artificial intelligence has moved slowly (though not always steadily) to a central place in our everyday lives, and how it will be even more crucial as the World Wide Web moves into its next generation.

Foreword	xi
Preface	xvii
Time Line: The Mechanization of Thinking	xxiii
Part I Beginnings
1 Brass for Brain	3	(34)
Surveys attempts before the twentieth century to create artificial intelligences, both literary and real. Argues that twentieth-century artificial intelligence is only the latest, though the most successful, instance of a long Western tradition, and shares much with its ancestors.
2 From Energy to Information	37	(22)
Delineates the early attempts of philosophers, and later psychologists, to define the mind, and the parallel attempts of mathematicians to turn human logic into rigorous mathematics. Shows that the dominant model for these thinkers was from physics, and that not until cybernetics introduced a new model-information in an open system, as opposed to energy in a closed system-could the computer successfully be used as a medium for intelligent behavior.
3 The Machinery of Wisdom	59	(26)
Focuses on the computer as a medium for intelligent behavior, with close attention to Alan Turing, a brilliant British logician who helped design one of the first computers and was responsible for much early work in artificial intelligence. Discusses the American pioneer John von Neumann, who held a view opposite to Turing's, that computers would never be able to "think."
4 Meat Machines	85	(26)
Traces the growing conviction that brains are a species of machine, the failed attempts to equate the on-off logic of the computer with the on-off logic of brain neurons. Reviews the early work of McCulloch and Pitts, as well as self-organizing systems, the Perceptron, and other attempts in the United States and Great Britain to link brains and machines.
Part II The Turning Point
5 The 'Dartmouth Conference	111	(26)
Reports on a conference that in 1956 gathered the threads of an assortment of projects with the same general underlying assumptions. Everyone was there, and the conference served as a rite of tribal identification that set patterns for future research and personal relations.
6 The Information-Processing Model	137	(34)
Covers the pioneering work of Newell, Shaw, and Simon, which set the tone for the next decade of research. The influence of these men on computing and cognitive psychology so pervades those fields that their discoveries and models are simply taken for granted.
7 Fun and Games	171	(24)
Describes how computers were taught to play chess and checkers, and why this development made IBM so nervous. Analyzes the scientific and social significance of computer games.
Part III Resistance
8 Us and Them	195	(16)
Discusses the critics of artificial intelligence, who give the lie to the idea that science is a disinterested enterprise. Includes some speculations as to why artificial intelligence seems to provoke people to extremes, and covers the first extremist, Mortimer Taube, author of Computers and Common Sense.
9 L'Affaire Dreyfus	211
Considers the bitterest critic of artificial intelligence, who examined the evidence and found it wanting. However, a computer walloped him at chess, and his demands continue to be met. (Or do they?) Dreyfus and his book What Computers Can't Do are introduced as fixtures in the artificial-intelligence community, and the man is presented as an example of the committed mind that finds only what it expects to find, even as scientists with the opposite commitment find what they expect to find. Relates prophecies, insults, and other scientific high jinks-a case study in the subjective side of science and philosophy.
Part IV Realizations
10 Robotics and General Intelligence	243	(34)
Investigates the robot and the difficulty of general, as opposed to special-purpose, intelligence. Presents two approaches, the General Problem Solver and the Advice Taker, and inspects some of the problems and solutions robot makers have encountered. Focuses on Shakey, the SRI robot, who rolled into the hearts and fears of millions-thanks to some scurrilous publicity.
11 Language, Scenes, Symbols, and Understanding	277	(40)
Views some of the interesting projects of the 1970's having to do with language, scenes, symbols, and understanding. Concentrates on language understanding, written and spoken, and parallel problems in visual analysis.
12 Applied Artificial Intelligence	317	(36)
Examines a here-and-now application of artificial intelligence in DENDRAL, the pro-gram that assists organic chemists, and some of its collateral programs. Looks at the MIT education laboratory, which applies artificial-intelligence principles in a different way.
Part V The Tensions of Choice
13 Can a Made-Up Mind Be Moral?	353	(28)
Asks the questions: Can artificial intelligence really be created? If it can, should it? Reflects on the moral and ethical dimensions of artificial intelligence. Reviews Weizenbaum's Computer Power and Human Reason and responses to it.
14 Forging the Gods	381	(36)
Appraises the central scientific claim of artificial intelligence: that it demonstrates how symbols can be embodied in a physical system, serving as a key to the understanding of mind as the theory of evolution was to the understanding of biology. Regards artificial intelligence as a bridge between science and art, telling us about ourselves in some startling ways. Speculates as to future directions.
Part V Afterword: The Following Quarter-Century of Artificial Intelligence	417	(106)
The next quarter-century: from celebrity status to fragmented has-been, and back to solid science; successful robots without symbolic intelligence raise big questions; skeptics continue to doubt and scientists continue to work at the job; achieving a major AI goal-a machine beats the world's chess champion-reveals new, more challenging goals; the growing realization that intelligence is both knowledge-based and collaborative; finally, the near future looks promising.
