The paper asks under what conditions deductive reasoning transmits justification from its premises to its conclusion. It argues that both standard externalist and standard internalist accounts of this phenomenon fail. The nature of this failure is taken to indicate the way forward: basic forms of deductive reasoning must justify by being instances of 'blind but blameless' reasoning. Finally, the paper explores the suggestion that an inferentialist account of the logical constants can help explain how such reasoning is possible.

By any reasonable reckoning, Gottlob Frege's ‘On Sense and Reference’ is one of the more important philosophical papers of all time. Although Frege briefly discusses the sense-reference distinction in an earlier work, it is through ‘Sense and Reference’ that most philosophers have become familiar with it. And the distinction so thoroughly permeates contemporary philosophy of language and mind that it is almost impossible to imagine these subjects without it.The distinction between the sense and the referent of a name is introduced (...) in the second paragraph of ‘Sense and Reference.’.

John McDowell has often emphasized the fact that the use of langauge is a rational enterprise. In this paper, I explore the sense in which this is so, arguing that our use of language depends upon our consciously knowing what our words mean. I call this a 'cognitive conception of semantic competence'. The paper also contains a close analysis of the phenomenon of implicature and some suggestions about how it should and should not be understood.

The paper argues, as against Thau and Caplan, that the traditional interpretation that Frege abandoned his earlier views about identity and identity--statements is correct.

Many philosophers nowadays believe Frege was right about belief, but wrong about language: The contents of beliefs need to be individuated more finely than in terms of Russellian propositions, but the contents of utterances do not. I argue that this 'hybrid view' cannot offer no reasonable account of how communication transfers knowledge from one speaker to another and that, to do so, we must insist that understanding depends upon more than just getting the references of terms right.

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)

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.

Demonstratives seem to have posed a severe difficulty for Frege’s philosophy of language, to which his doctrine of incommunicable senses was a reaction. In “The Thought,” Frege briefly discusses sentences containing such demonstratives as “today,” “here,” and “yesterday,” and then turns to certain questions that he says are raised by the occurrence of “I” in sentences (T, 24-26). He is led to say that, when one thinks about oneself, one grasps thoughts that others cannot grasp, that cannot be communicated. However, (...) nothing could be more out of the spirit of Frege’s account of sense and thought than an incommunicable, private thought. In the first part of the paper, I explain the problem demonstratives pose for Frege, and explore three ways he might have dealt with it. I argue that none of these ways provides Frege with a solution to his problem consistent with his philosophy of language. The first two are plausible as solutions, but contradict his identification of the sense expressed by a sentence with a thought. The third preserves the identification, but is implausible. In the second part, I suggest that Frege was led to his doctrine of incommunicable senses as a result of some appreciation of the difficulties his account of demonstratives faces, for these come quickly to the surface when we think about “I.” I argue that incommunicable senses won’t help. I end by trying to identify the central problem with Frege’s approach, and sketching an alternative. (shrink)

In this paper, I argue that certain perceptual relations are represented in visual experience.

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)

What would something unlike us--a chimpanzee, say, or a computer--have to be able to do to qualify as a possible knower, like us? To answer this question at the very heart of our sense of ourselves, philosophers have long focused on intentionality and have looked to language as a key to this condition. Making It Explicit is an investigation into the nature of language--the social practices that distinguish us as rational, logical creatures--that revises the very terms of this inquiry. Where (...) accounts of the relation between language and mind have traditionally rested on the concept of representation, this book sets out an alternate approach based on inference, and on a conception of certain kinds of implicit assessment that become explicit in language. Making It Explicit is the first attempt to work out in detail a theory that renders linguistic meaning in terms of use--in short, to explain how semantic content can be conferred on expressions and attitudes that are suitably caught up in social practices. -/- At the center of this enterprise is a notion of discursive commitment. Being able to talk--and so in the fullest sense being able to think--is a matter of mastering the practices that govern such commitments, being able to keep track of one’s own commitments and those of others. Assessing the pragmatic significance of speech acts is a matter of explaining the explicit in terms of the implicit. As he traces the inferential structure of the social practices within which things can be made conceptually explicit, the author defines the distinctively expressive role of logical vocabulary. This expressive account of language, mind, and logic is, finally, an account of who we are. (shrink)

Now in a new edition, this volume updates Davidson's exceptional Inquiries into Truth and Interpretation (1984), which set out his enormously influential philosophy of language. The original volume remains a central point of reference, and a focus of controversy, with its impact extending into linguistic theory, philosophy of mind, and epistemology. Addressing a central question--what it is for words to mean what they do--and featuring a previously uncollected, additional essay, this work will appeal to a wide audience of philosophers, linguists, (...) and psychologists.

A major obstacle to formulating a broad-content intentional psychology is the occurrence of ''Frege cases'' - cases in which a person apparently believes or desires Fa but not Fb and acts accordingly, even though "a" and "b" have the same broad content. Frege cases seem to demand narrow-content distinctions to explain actions by the contents of beliefs and desires. Jerry Fodor ( The elm and the expert: Mentalese and its semantics , Cambridge, MA: MIT Press, 1994) argues that an explanatorily (...) adequate broad-content psychology is nonetheless possible because Frege cases rarely occur in intentional-explanatory contexts, and they are not systematically linked to intentional laws in a way that demands intentional explanation. Thus, he claims, behaviors associated with Frege cases can be considered ceteris-paribus exceptions to broad-content intentional laws without significantly decreasing the explanatory power of intentional psychology. I argue that Frege cases are plentiful and systematically linked to intentional laws in a way that requires intentional explanation, specifically in the explanation of why certain actions are not performed. Consequently, Frege-case behaviors cannot be construed as ceteris-paribus exceptions to intentional laws without significantly eroding the explanatory power of intentional psychology and reducing the rationality of the agent. Fodor thus fails to save broad-content psychology from the prima facie objections against it based on Frege cases. (shrink)

This paper is a discussion of Michael Thau's interesting critique in Chapter 2 of Consciousness and Cognition, Oxford: Oxford University Press, 2002, of the common view that beliefs are internal states.

This book makes a stimulating contribution to the philosophy of language and philosophy of mind. It begins with a spirited defence of the view that propositions are structured and that propositional structure is 'psychologically real'. The author then develops a subtle view of propositions and attitude ascription. The view is worked out in detail with attention to such topics as the semantics of conversations, iterated attitude ascriptions, and the role of propositions as bearers of truth. Along the way important issues (...) in the philosophy of mind are addressed. Though intended primarily for professional philosophers and graduate students the book will also interest cognitive scientists and linguists. (shrink)

In this paper, I defend a well-known theory of belief reports from an important objection. The theory is Russellianism, sometimes also called `neo-Russellianism', `Millianism', `the direct reference theory', `the "Fido"-Fido theory', or `the naive theory'. The objection concernssubstitution of co-referring names in belief sentences. Russellianism implies that any two belief sentences, that differ only in containing distinct co-referring names, express the same proposition (in any given context). Since `Hesperus' and `Phosphorus' both refer to the planet Venus, this view implies that (...) all utterances of (1) and.. (shrink)

How many senses can a given name have, with its reference held fixed? One, more than one? One answer that most would agree to is that sense is unique for each utterance of a name, that is, that a name can have no more than one sense on any given occasion. But is sense unique in any stronger sense than this? The answer that is typically attributed to Frege is that there is not, that, as Tyler Burge puts it, 1 (...) Frege “treats proper names as having different senses while applying to the same person.” There are a number of possibilities for the locus of this multiplicity of sense; the following remark by Ruth Marcus indicates the possibilities: “the sense of a term is whatever is grasped or understood by a speaker on a particular occasion of use and may vary from occasion to occasion as well as from speaker to speaker.”2 Of the views canvassed by Marcus, we can draw out a more conservative one, and one more extreme. On the more conservative view, Frege is holding that sense may vary from speaker to speaker; on the more extreme view, Frege holds not only this, but that sense may vary from context to context. Endorsements of the two views are not hard to find. For example, typical sorts of endorsement of the conservative view are found in Harold Noonan’s remark that “different senses [are] associated with the name ‘Aris-. (shrink)

The paper challenges the inferentialist account of concept possession that Paul Boghossian takes as a premise in his account of the transmission of justification by deductive reasoning in his paper 'Blind Reasoning'. Unorthodox speakers who reject the inferences in an alleged possession condition can still have the concept by understanding a word for it. In that sense, the inferences are not analytic. Inferentialist accounts of logical constants, theoretical terms (using the Ramsey-Carnap-Lewis method) and pejorative expressions such as 'Boche' are examined (...) and rejected. It is suggested that epistemological questions cannot be reduced to questions in the theory of thought and meaning. (shrink)

Modern applications of logic in mathematics, computer science, and linguistics use combined systems of different types of logic working together. This book develops a method for combining--or fibring--systems by breaking them into simple components which can be manipulated easily and recombined.

This book maintains that our conception of consciousness and cognition begins with and depends upon a few fundamental errors. Thau elucidates these errors by discussing three important philosophical puzzles - Spectrum Inversion, Frege's Puzzle, and Black-and-White Mary - each of which concerns some aspect of either consciousness or cognition. He argues that it has gone unnoticed that each of these puzzles presents the very same problem and, in bringing this commonality to light, the errors in our natural conception of consciousness (...) and cognition are also reviewed.

Five symposia from the 25th annual Oberlin Colloquium in Philosophy focus on cognitive suicide, the explanatory role of content, Cartesian error and the objectivity of perception, social content and psychological content, and belief attribution and context.
