This paper develops a criterion for sameness of Fregean senses. I consider three criteria: logical equivalence, intensional isomorphism, and epistemic equipollence. I reject the first two and argue for a version of the third.

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

What does it take to count as competent with the meaning of a thin evaluative predicate like 'is the right thing to do'? According to minimalists like Allan Gibbard and Ralph Wedgwood, competent speakers must simply use the predicate to express their own motivational states. According to analytic descriptivists like Frank Jackson, Philip Pettit and Christopher Peacocke, competent speakers must grasp a particular criterion for identifying the property picked out by the term. Both approaches face serious difficulties. We suggest that (...) these difficulties derive from a shared background assumption that competence conditions must be explained in terms of a determinate conceptual role. We propose a new way of characterizing competence with evaluative terms: what's required for competence is participation in a shared epistemic practice with a term. Our approach, we argue, better explains the nature of evaluative inquiry and the extent of disagreement about evaluative questions. (shrink)

Introducing a new and ambitious position in the field, Kit Fine’s _Semantic Relationism_ is a major contribution to the philosophy of language. Written by one of today’s most respected philosophers Argues for a fundamentally new approach to the study of representation in language and thought Proposes that there may be representational relationships between expressions or elements of thought that are not grounded in the intrinsic representational features of the expressions or elements themselves Forms part of the prestigious new _Blackwell/Brown Lectures (...) in Philosophy_ series, based on an ongoing series of lectures by today’s leading philosophers.

This book examines some of the deepest questions in philosophy: What is involved in judging a belief, action, or feeling to be rational?

Frank Jackson often writes as if his descriptivist account of public language meanings were just plain common sense. How else are we to explain how different speakers manage to communicate using a public language? And how else can we explain how individuals arrive at confident judgments about the reference of their words in hypothetical scenarios? Our aim in this paper is to show just how controversial the psychological assumptions behind in Jackson’s semantic theory really are. First, we explain how Jackson’s (...) theory goes well beyond the commonsense platitudes he cites in its defence. Second, we sketch an alternative explanation of those platitudes, the jazz model of meaning, which we argue is more psychologically realistic. We conclude that the psychological picture presupposed by Jackson’s semantic theory stands in need of a much more substantial defence than he has so far offered. (shrink)

Tyler Burge defends the idea that memory preserves beliefswith their justifications, so that memory's role in inferenceadds no new justificatory demands. Against Burge's view,Christensen and Kornblith argue that memory is reconstructiveand so introduces an element of a posteriori justificationinto every inference. I argue that Burge is right,memory does preserve content, but to defend this viewwe need to specify a preservative mechanism. Toward thatend, I develop the idea that there is something worthcalling anaphoric thinking, which preserves content inBurge's sense of ``content (...) preservation.'' I providea model on which anaphoric thought is a fundamentalfeature of cognitive architecture, consequentlyrejecting the idea that there are mental pronounsin a Language of Thought. Since preservativememory is a matter of anaphoric thinking, thereare limits on the analogy of memory and testimony. (shrink)

Conceptual analysis is undergoing a revival in philosophy, and much of the credit goes to Frank Jackson. Jackson argues that conceptual analysis is needed as an integral component of so-called serious metaphysics and that it also does explanatory work in accounting for such phenomena as categorization, meaning change, communication, and linguistic understanding. He even goes so far as to argue that opponents of conceptual analysis are implicitly committed to it in practice. We show that he is wrong on all of (...) these points and that his case for conceptual analysis doesn't succeed. At the same time, we argue that the sorts of intuitions that figure in conceptual analysis may still have a significant role to play in philosophy. So naturalists needn't disregard intuitions altogether. (shrink)

What knowledge would suffice to yield an interpretation of an arbitrary utterance of a language when such knowledge is based on evidence plausibly available to a nonspeaker of that language? it is argued that it is enough to know a theory of truth for the language and that the theory satisfies tarski's 'convention t' and that it gives an optimal fit to data about sentences held true, Under specified conditions, By native speakers.

Two-dimensional approaches to semantics, broadly understood, recognize two "dimensions" of the meaning or content of linguistic items. On these approaches, expressions and their utterances are associated with two different sorts of semantic values, which play different explanatory roles. Typically, one semantic value is associated with reference and ordinary truth-conditions, while the other is associated with the way that reference and truth-conditions depend on the external world. The second sort of semantic value is often held to play a distinctive role in (...) analyzing matters of cognitive significance and/or context-dependence. (shrink)

This paper concerns the applications of two-dimensional modal semantics to the explanation of the contents of speech and thought. Different interpretations and applications of the apparatus are contrasted. First, it is argued that David Kaplan's two-dimensional semantics for indexical expressions is different from the use that I made of a formally similar framework to represent the role of contingent information in the determination of what is said. But the two applications are complementary rather than conflicting. Second, my interpretation of the (...) apparatus is contrasted with that of David Chalmers, Frank Jackson, and David Lewis. It is argued that this difference reflects a contrast between internalist and externalist approaches to the problem of intentionality. (shrink)

What is involved in the meaning of our expressions? Frege suggested that there is an aspect of an expression.

Why is two-dimensional semantics important? One can think of it as the most recent act in a drama involving three of the central concepts of philosophy: meaning, reason, and modality. First, Kant linked reason and modality, by suggesting that what is necessary is knowable a priori, and vice versa. Second, Frege linked reason and meaning, by proposing an aspect of meaning (sense) that is constitutively tied to cognitive signi?cance. Third, Carnap linked meaning and modality, by proposing an aspect of meaning (...) (intension) that is constitutively tied to possibility and necessity. (shrink)

I believe that the notion of epistemic transparency does play an important role in our ordinary conception of mental content and I want to say what that role is. Unfortunately, the task is a large one; here I am able only to begin on its outline. I shall proceed somewhat indirectly, beginning with a discussion of externalist conceptions of mental content. I shall show that such conceptions violate epistemic transparency to an extent that has not been fully appreciated. Subsequently, I (...) shall look at the implications of this violation and at the reconstructive project that a rejection of transparency entails. I am inclined to think it unlikely that we will get a conception of propositional content that underwrites epistemic transparency. But I am concerned that we have not fully appreciated the role that transparency currently plays and the work that would need to be done were we to discard it. (shrink)

Anti-individualists claim that concepts are individuated with an eye to purely external facts about a subject's environment about which she may be ignorant or mistaken. This paper offers a novel reason for thinking that anti-individualistic concepts are an ineliminable part of commonsense psychology. Our commitment to anti-individualism, I argue, is ultimately grounded in a rational epistemic agent's commitment to refining her own representational practices in the light of new and surprising information about her environment. Since anti-individualism is an implicit part (...) of responsible epistemic practices, we cannot abandon it without compromising our own epistemic agency. The story I tell about the regulation of one's own representational practices yields a new account of the identity conditions for anti-individualistic concepts. (shrink)

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.

Is conceptual analysis required for reductive explanation? If there is no a priori entailment from microphysical truths to phenomenal truths, does reductive explanation of the phenomenal fail? We say yes . Ned Block and Robert Stalnaker say no.

Frank Jackson champions the cause of conceptual analysis as central to philosophical inquiry. In recent years conceptual analysis has been undervalued and widely misunderstood, suggests Jackson. He argues that such analysis is mistakenly clouded in mystery, preventing a whole range of important questions from being productively addressed. He anchors his argument in discussions of specific philosophical issues, starting with the metaphysical doctrine of physicalism and moving on, via free will, meaning, personal identity, motion, and change, to ethics and the philosophy (...) of color. In this way the book not only offers a methodological program for philosophy, but also casts new light on some much-debated problems and their interrelations. (shrink)

According to David Chalmers and Frank Jackson, conceptual competence puts one in a position to have a priori knowledge of conditional claims of the form ‘If my environment is thus and so, then water = H2O’. The rationale for this position, I argue, rests on controversial semantic assumptions about the individuation of meanings or concepts. I sketch a new model of conceptual competence, which undermines the apriority of such conditionals.

The explanatory gap . Consciousness is a mystery. No one has ever given an account, even a highly speculative, hypothetical, and incomplete account of how a physical thing could have phenomenal states. Suppose that consciousness is identical to a property of the brain, say activity in the pyramidal cells of layer 5 of the cortex involving reverberatory circuits from cortical layer 6 to the thalamus and back to layers 4 and 6,as Crick and Koch have suggested for visual consciousness. .) (...) Still, that identity itself calls out for explanation! Proponents of an explanatory gap disagree about whether the gap is permanent. Some say that we are like the scientifically naive person who is told that matter = energy, but does not have the concepts required to make sense of the idea. If we can acquire these concepts, the gap is closable. Others say the gap is uncloseable because of our cognitive limitations. Still others say that the gap is a consequence of the fundamental nature of consciousness. (shrink)

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible , and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and arguments developed earlier to defend (...) a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

The second volume in the _Blackwell Brown Lectures in Philosophy_, this volume offers an original and provocative take on the nature and methodology of philosophy. Based on public lectures at Brown University, given by the pre-eminent philosopher, Timothy Williamson Rejects the ideology of the 'linguistic turn', the most distinctive trend of 20th century philosophy Explains the method of philosophy as a development from non-philosophical ways of thinking Suggests new ways of understanding what contemporary and past philosophers are doing.

_the a priori role_ (for word T). For instance, perhaps anyone who understands the word _water_ is able to know, without appeal to any further a posteriori information, that _water_ refers to the clear, drinkable natural kind whose instances are predominant in our oceans and lakes (if _water_ refers at all.

It is beliefs of this sort--de linguabeliefs--that Robert Fiengo and Robert May explore in this book.

_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)

Written by one of today's most creative and innovative philosophers, Ruth Garrett Millikan, this book examines basic empirical concepts; how they are acquired, how they function, and how they have been misrepresented in the traditional philosophical literature. Millikan places cognitive psychology in an evolutionary context where human cognition is assumed to be an outgrowth of primitive forms of mentality, and assumed to have 'functions' in the biological sense. Of particular interest are her discussions of the nature of abilities as different (...) from dispositions, her detailed analysis of the psychological act of reidentifying substances, and her critique of the language of thought for mental representation. In a radical departure from current philosophical and psychological theories of concepts, this book provides the first in-depth discussion on the psychological act of reidentification. (shrink)

Philosophers from Hume, Kant, and Wittgenstein to the recent realists and antirealists have sought to answer the question, What are concepts? This book provides a detailed, systematic, and accessible introduction to an original philosophical theory of concepts that Christopher Peacocke has developed in recent years to explain facts about the nature of thought, including its systematic character, its relations to truth and reference, and its normative dimension. Particular concepts are also treated within the general framework: perceptual concepts, logical concepts, and (...) the concept of belief are discussed in detail. The general theory is further applied in answering the question of how the ontology of concepts can be of use in classifying mental states, and in discussing the proper relation between philosophical and psychological theories of concepts. Finally, the theory of concepts is used to motivate a nonverificationist theory of the limits of intelligible thought. Peacocke treats content as broad rather than narrow, and his account is nonreductive and non-Quinean. Yet Peacocke also argues for an interactive relationship between philosophical and psychological theories of concepts, and he plots many connections with work in cognitive psychology. (shrink)

Everyone has mistaken one thing for another, such as a stranger for an acquaintance. A person who has mistaken two things, Joseph Camp argues, even on a massive scale, is still capable of logical thought. In order to make that idea precise, one needs a logic of confused thought that is blind to the distinction between the objects that have been confused. Confused thought and language cannot be characterized as true or false even though reasoning conducted in such language can (...) be classified as valid or invalid. To the extent that philosophers have addressed this issue at all, they take it for granted that confusion is a kind of ambiguity. Camp rejects this notion; his fundamental claim is that confusion is not a mental state. To attribute confusion to someone is to take up a paternalistic stance in evaluating his reasoning. Camp proposes a novel characterization of confusion, and then demonstrates its fruitfulness with several applications in the history of philosophy and the history of science. (shrink)

It would be nice if good old a priori conceptual analysis were possible. For many years conceptual analysis was out of fashion, in large part because of the excessive ambitions of verificationist theories of meaning._ _However, those days are over._ _A priori conceptual analysis is once again part of the philosophical mainstream._ _This renewed popularity, moreover, is well-founded. Modern philosophical analysts have exploited developments in philosophical semantics to formulate analyses which avoid the counterintuitive consequences of verificationism, while vindicating our ability (...) to know a priori precisely what it is our words and thoughts represent._ _Despite its apparent promise, however, I.

Frank Jackson and David Chalmers have suggested that the diagonal intensions defined by their two-dimensional framework can play the two key roles of Fregean senses: they provide a priori accessible extension conditions for a representation and they provide the identity conditions for meanings and thought contents. In this paper, I clarify the nature of the psychological abilities that are needed to underwrite the first role. I then argue that these psychological abilities are not sufficiently stable or cognitively salient to individuate (...) meanings or thought contents. (shrink)
