In chapter 1 of Reason, Truth, and History, Hilary Putnam argues from some plausible assumptions about the nature of reference to the conclusion that it is not possible that all sentient creatures are brains in a vat. If this argument is successful, it seemingly refutes an updated form of Cartesian skepticism concerning knowledge of physical objects. In this paper, I will state what I take to be the most promising interpretation of Putnam's argument. My reconstructed argument differs from an argument (...) strongly suggested by Putnam's text. I will show that the latter argument obviously does not work. The more promising argument which I reconstruct on behalf of Putnam raises some interesting questions about the relation between the contents of one's beliefs and one's environment and about how this relation affects the evaluation of anti-skeptical arguments. I conclude that my reconstructed argument ultimately fails as a response to Cartesian skepticism: the argument engenders a skepticism about knowledge of meaning, or propositional content, which undercuts its anti-skeptical force.

Provides a comprehensive introduction to the major philosophical theories attempting to explain the workings of language.

This volume contains all of Frege's extant unpublished writings on philosophy and logic other than his correspondence, written at various stages of his career.

The paper explores the distinction between two doctrines, both of which inform theory construction in much of modern cognitive psychology: the representational theory of mind and the computational theory of mind. According to the former, propositional attitudes are to be construed as relations that organisms bear to mental representations. According to the latter, mental processes have access only to formal (nonsemantic) properties of the mental representations over which they are defined.The following claims are defended: (1) That the traditional dispute between (...) “rational” and “naturalistic” psychology is plausibly viewed as an argument about the status of the computational theory of mind. Rational psychologists accept a formality condition on the specification of mental processes; naturalists do not. (2) That to accept the formality condition is to endorse a version of methodological solipsism. (3) That the acceptance of some such condition is warranted, at least for that part of psychology which concerns itself with theories of the mental causation of behavior. This is because: (4) such theories require nontransparent taxonomies of mental states; and (5) nontransparent taxonomies individuate mental states without reference to their semantic properties. Equivalently, (6) nontransparent taxonomies respect the way that the organism represents the object of its propositional attitudes toitself, and it is this representation which functions in the causation of behavior.The final section of the paper considers the prospect for a naturalistic psychology: one which defines its generalizations over relations between mental representations and their environmental causes, thus seeking to account for the semantic properties of propositional attitudes. Two related arguments are proposed, both leading to the conclusion that no such research strategy is likely to prove fruitful. (shrink)

_Naming and Necessity_ has had a great and increasing influence. It redirected philosophical attention to neglected questions of natural and metaphysical necessity and to the connections between these and theories of naming, and of identity. This seminal work, to which today's thriving essentialist metaphysics largely owes its impetus, is here reissued in a newly corrected form with a new preface by the author. If there is such a thing as essential reading in metaphysics, or in philosophy of language, this is (...) it. (shrink)

This is the 1991 (2nd) edition of the 1986 book (MIT Press), considered to be the classic defense of Millianism. The nature of the information content of declarative sentences is a central topic in the philosophy of language. The natural view that a sentence like "John loves Mary" contains information in which two individuals occur as constituents is termed the naive theory, and is one that has been abandoned by most contemporary scholars. This theory was refuted originally by philosopher Gottlob (...) Frege. His argument that the naive theory did not work is termed Frege's puzzle, and his rival account of information content is termed the orthodox theory. In this detailed study, Nathan Salmon defends a version of the naive theory and presents a proposal for its extension that provides a better picture of information content than the orthodox theory gives. He argues that a great deal of what has generally been taken for granted in the philosophy of language over the past few decades is either mistaken or unsupported, and consequently, much current research is focused on the wrong set of questions. Salmon dissolves Frege's puzzle as it is usually formulated and demonstrates how it can be reconstructed and strengthened to yield a more powerful objection to the naive theory. He then defends the naive theory against the new Frege puzzle by presenting an idea that yields both a surprisingly rich and powerful extension of the naive theory and a better picture of information content than that of the original orthodox theory. Nathan Salmon is Professor of Philosophy, University of California at Santa Barbara. (shrink)

"This book is valuable as expounding in full a theory of meaning that has its roots in the work of Frege and has been of the widest influence.

In this collection of new essays, six philosophers address themselves to the question of what sort of feature this intentional content is. The topics covered in the individual papers are of great independent interest and subject to much recent discussion.

In this book Saul Kripke brings his powerful philosophical intelligence to bear on Wittgenstein's analysis of the notion of following a rule.

Perry argues that certain sorts of indexicals are 'essential', in the sense that they cannot be eliminated in favor of descriptions. This paper also introduces the influential idea that certain sorts of indexicals play a special role in thought, and have a special connection to action.

A transcript of three lectures, given at Princeton University in 1970, which deals with (inter alia) debates concerning proper names in the philosophy of language.

Are mental states "in the head"? Or do they intrinsically involve aspects of the subject's physical and social context? This volume presents a number of essays dealing with the compass of the mind. The contributors broach a range of issues with a commmon view that physical and social magnets do act upon mental states. The approaches that run through these papers make the volume challenging to cognitive psychologists, theorists of artificial intelligence, social theorists, and philosophers.

A venerable view, still very much alive, holds that human action is to be explained at least in part in terms of beliefs and desires. Those who advocate the view expect that the psychological theory which explains human behavior will invoke the concepts of belief and desire in a substantive way. I will call this expectation the belief-desire thesis. Though there would surely be a quibble or a caveat here and there, the thesis would be endorsed by an exceptionally heterogeneous (...) collection of psychologists and philosophers ranging from Freud and Hume, to Thomas Szasz and Richard Brandt. Indeed, a number of philosophers have contended that the thesis, or something like it, is embedded in our ordinary, workaday concept of action. If they are right, and I think they are, then insofar as we use the concept of action we are all committed to the belief-desire thesis. My purpose in this paper is to explore the tension between the belief-desire thesis and a widely held assumption about the nature of explanatory psychological theories, an assumption that serves as a fundamental regulative principle for much of contemporary psychological theorizing. This assumption, which for want of a better term I will call the principle of psychological autonomy, will be the focus of the first of the sections below. In the second section I will elaborate a bit on how the belief-desire thesis is to be interpreted, and try to extract from it a principle that will serve as a premise in the argument to follow. In the third section I will set out an argument to the effect that large numbers of belief-desire explanations of action, indeed perhaps the bulk of such explanations, are incompatible with the principle of autonomy. Finally, in the last section, I will fend off a possible objection to my argument. In the process, I will try to make clear just why the argument works and what price we should have to pay if we were resolved to avoid its consequences. (shrink)

Aimed at philsophy graduates this book investigates mental content in a systematic way and advances a number of claims about how mental content states are related to the body and the world. Internalism is the thesis that they are; externalism is the theory that they are not.
