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)

Essays analyze the nature of the human mind, thought, and imagination and explore the connection of thought to teaching.

Thoughts and other mental states are defined by their role in a functional system. Since it is easier to determine when we have knowledge than when reasoning has occurred, Gilbert Harman attempts to answer the latter question by seeing what assumptions about reasoning would best account for when we have knowledge and when not. He describes induction as inference to the best explanation, or more precisely as a modification of beliefs that seeks to minimize change and maximize explanatory coherence. Originally (...) published in 1973. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This is the third edition of Chomsky's outstanding collection of essays on language and mind, first published in 2006. The first six chapters, originally published in the 1960s, made a groundbreaking contribution to linguistic theory. This edition complements them with an additional chapter and a new preface, bringing Chomsky's influential approach into the twenty-first century. Chapters 1-6 present Chomsky's early work on the nature and acquisition of language as a genetically endowed, biological system, through the rules and principles of which (...) we acquire an internalized knowledge. Over the past fifty years, this framework has sparked an explosion of inquiry into a wide range of languages, and has yielded some major theoretical questions. The final chapter revisits the key issues, reviewing the 'biolinguistic' approach that has guided Chomsky's work from its origins to the present day, and raising some novel and exciting challenges for the study of language and mind.

v. 1. The collective use and evolution of concepts.

The question I hope to answer is brief: What does every speaker of a natural language know? My answer is briefer still: Nothing, or at least nothing interesting. Explaining the question, and making the answer plausible, is a longer job.

This article is an introduction to current issues in the field via a brief review of the history of the field since ryle's "the concept of mind" in 1949. The contributions of ordinary language philosophy and the first wave of identity theory provide the background for the development of the various brands of functionalism that occupy the center of attention today. Problems with functionalism concerned with mental representation, "qualia" and other presumed features of conscious experience are examined. There is an (...) extensive bibliography. (shrink)

This edition's postscript includes further reflections on these themes and others, and relates them to recent writings of other philosophers and computer ...

_Zettel, _ an en face bilingual edition, collects fragments from Wittgenstein's work between 1929 and 1948 on issues of the mind, mathematics, and language.

According to Quine, the linguist qua grammarian does not know what he is talking about. The goal of this essay is to tell him. My aim is to provide an account of what the grammarian is saying of an expression when he says it is grammatical, or a noun phrase, or ambiguous, or the subject of a certain sentence. More generally, I want to give an account of the nature of a generative grammatical theory of a language – of the (...) data for such a theory, the relation between the theory and the data, and the relation between the theory and a speaker of the language.
