An Invitation to Cognitive Science provides a point of entry into the vast realm of cognitive science, offering selected examples of issues and theories from many of its subfields. All of the volumes in the second edition contain substantially revised and as well as entirely new chapters.

Rather than surveying theories and data in the manner characteristic of many introductory textbooks in the field, An Invitation to Cognitive Science employs a unique case study approach, presenting a focused research topic in some depth and relying on suggested readings to convey the breadth of views and results. Each chapter tells a coherent scientific story, whether developing themes and ideas or describing a particular model and exploring its implications.

The volumes are self contained and can be used individually in upper-level undergraduate and graduate courses ranging from introductory psychology, linguistics, cognitive science, and decision sciences, to social psychology, philosophy of mind, rationality, language, and vision science.

In this major new work, John Searle launches a formidable attack on current orthodoxies in the philosophy of mind. More than anything else, he argues, it is the neglect of consciousness that results in so much barrenness and sterility in psychology, the philosophy of mind, and cognitive science: there can be no study of mind that leaves out consciousness. What is going on in the brain is neurophysiological processes and consciousness and nothing more - no rule following, no mental information processing or mental models, no language of thought, and no universal grammar. Mental events are themselves features of the brain, "like liquidity is a feature of water."

Beginning with a spirited discussion of what's wrong with the philosophy of mind, Searle characterizes and refutes the philosophical tradition of materialism. But he does not embrace dualism. All these "isms" are mistaken, he insists. Once you start counting types of substance you are on the wrong track, whether you stop at one or two. In four chapters that constitute the heart of his argument, Searle elaborates a theory of consciousness and its relation to our overall scientific world view and to unconscious mental phenomena. He concludes with a criticism of cognitive science and a proposal for an approach to studying the mind that emphasizes the centrality of consciousness to any account of mental functioning.

In his characteristically direct style, punctuated with persuasive examples, Searle identifies the very terminology of the field as the main source of truth. He observes that it is a mistake to suppose that the ontology of the mental is objective and to suppose that the methodology of a science of the mind must concern itself only with objectively observable behavior; that it is also a mistake to suppose that we know of the existence of mental phenomena in others only by observing their behavior; that behavior or causal relations to behavior are not essential to the existence of mental phenomena; and that it is inconsistent with what we know about the universe and our place in it to suppose that everything is knowable by us.

John R. Searle is Professor of Philosophy at the University of California, Berkeley.

The Very Idea

"Machines who think—how utterly preposterous," huff beleaguered humanists, defending their dwindling turf. "Artificial Intelligence—it's here and about to surpass our own," crow techno-visionaries, proclaiming dominion. It's so simple and obvious, each side maintains, only a fanatic could disagree.

Deciding where the truth lies between these two extremes is the main purpose of John Haugeland's marvelously lucid and witty book on what artificial intelligence is all about. Although presented entirely in non-technical terms, it neither oversimplifies the science nor evades the fundamental philosophical issues. Far from ducking the really hard questions, it takes them on, one by one.

Artificial intelligence, Haugeland notes, is based on a very good idea, which might well be right, and just as well might not. That idea, the idea that human thinking and machine computing are "radically the same," provides the central theme for his illuminating and provocative book about this exciting new field. After a brief but revealing digression in intellectual history, Haugeland systematically tackles such basic questions as: What is a computer really? How can a physical object "mean" anything? What are the options for computational organization? and What structures have been proposed and tried as actual scientific models for intelligence?

In a concluding chapter he takes up several outstanding problems and puzzles—including intelligence in action, imagery, feelings and personality—and their enigmatic prospects for solution.

A Contemporary Introduction to the Philosophy of Mind

In Matter and Consciousness, Paul Churchland clearly presents the advantages and disadvantages of such difficult issues in philosophy of mind as behaviorism, reductive materialism, functionalism, and eliminative materialism. This new edition incorporates the striking developments that have taken place in neuroscience, cognitive science, and artificial intelligence and notes their expanding relevance to philosophical issues.

Churchland organizes and clarifies the new theoretical and experimental results of the natural sciences for a wider philosophical audience, observing that this research bears directly on questions concerning the basic elements of cognitive activity and their implementation in real physical systems. (How is it, he asks, that living creatures perform some cognitive tasks so swiftly and easily, where computers do them only badly or not at all?) Most significant for philosophy, Churchland asserts, is the support these results tend to give to the reductive and the eliminative versions of materialism.
