What psychological and philosophical significance should we attach to recent efforts at computer simulations of human cognitive capacities? In answering this question, I find it useful to distinguish what I will call "strong" AI from "weak" or "cautious" AI. According to weak AI, the principal value of the computer in the study of the mind is that it gives us a very powerful tool. For example, it enables us to formulate and test hypotheses in a more rigorous and precise fashion. (...) But according to strong AI, the computer is not merely a tool in the study of the mind; rather, the appropriately programmed computer really is a mind, in the sense that computers given the right programs can be literally said to.

I propose to consider the question, "Can machines think?" This should begin with definitions of the meaning of the terms "machine" and "think." The definitions might be framed so as to reflect so far as possible the normal use of the words, but this attitude is dangerous, If the meaning of the words "machine" and "think" are to be found by examining how they are commonly used it is difficult to escape the conclusion that the meaning and the answer to (...) the question, "Can machines think?" is to be sought in a statistical survey such as a Gallup poll. But this is absurd. Instead of attempting such a definition I shall replace the question by another, which is closely related to it and is expressed in relatively unambiguous words. The new form of the problem can be described in terms of a game which we call the 'imitation game." It is played with three people, a man (A), a woman (B), and an interrogator (C) who may be of either sex. The interrogator stays in a room apart front the other two. The object of the game for the interrogator is to determine which of the other two is the man and which is the woman. He knows them by labels X and Y, and at the end of the game he says either "X is A and Y is B" or "X is B and Y is A." The interrogator is allowed to put questions to A and B. We now ask the question, "What will happen when a machine takes the part of A in this game?" Will the interrogator decide wrongly as often when the game is played like this as he does when the game is played between a man and a woman? These questions replace our original, "Can machines think?". (shrink)

The philosophy of mind has always been a staple of the philosophy curriculum. But it has never held a more important place than it does today, with both traditional problems and new topics often sparked by the developments in the psychological, cognitive, and computer sciences. Jaegwon Kim’s Philosophy of Mind is the classic, comprehensive survey of the subject. Now in its second edition, Kim explores, maps, and interprets this complex and exciting terrain. Designed as an introduction to the field for (...) upper-level undergraduates and graduate students, Philosophy of Mind focuses on the mind/body problem and related issues, some touching on the status of psychology and cognitive science. The second edition features a new chapter on Cartesian substance dualism-a perspective that has been little discussed in the mainstream philosophy of mind and almost entirely ignored in most introductory books in philosophy of mind. In addition, all the chapters have been revised and updated to reflect the trends and developments of the last decade. Throughout the text, Kim allows readers to come to their own terms with the central problems of the mind. At the same time, the author’s own emerging views are on display and serve to move the discussion forward. Comprehensive, clear, and fair, Philosophy of Mind is a model of philosophical exposition. It is a major contribution to the study and teaching of the philosophy of mind. (shrink)
