Provided we agree about the thing, it is needless to dispute about the terms. —David Hume, A treatise of human nature, Book 1, section VIIMap-like representations are frequently invoked as an alternative type of representational vehicle to a language of thought. This view presupposes that map-systems and languages form legitimate natural kinds of cognitive representational systems. I argue that they do not, because the collections of features that might be taken as characteristic of maps or languages do not themselves provide (...) scientifically useful information above and beyond what the individual features provide. To bring this out, I sketch several allegedly distinctive features of maps, and show how they can easily be grafted onto a simple logical language, resulting in a hybrid “manguage.” The ease with which these linguistic and map-like properties can be integrated into a single representational system raises the question of what work broader categories like language and map are doing. I maintain that, as an empirical matter of fact, they serve no particular purpose in cognitive science, and thus do not characterize distinct kinds of cognitive architectures. (shrink)

This article argues that the much-maligned ‘notational variants’ of a given formal linguistic theory play a role similar to alternative numerical measurement scales. Thus, they can be used to identify the invariant components of the grammar; i.e., those features that do not depend on the choice of empirically equivalent representation. Treating these elements as the ‘meaningful’ structure of language has numerous consequences for the philosophy of science and linguistics. I offer several such examples of how linguistic theorizing can profit from (...) adopting a measurement-theoretic viewpoint. The first concerns a measurement-theoretic response to a famous criticism of Quine's. Others follow from issues of simplicity in the current biolinguistics program. An unexpected similarity with behaviorist practices is also uncovered. I then argue that managable and useful steps can be taken in this area. (shrink)

The structure of words is often thought to provide important evidence regarding the structure of concepts. At the same time, most contemporary linguists posit a great deal of structure in words. Such a trend makes some atomists about concepts uncomfortable. The details of linguistic methodology undermine several strategies for avoiding positing structure in words. I conclude by arguing that there is insufficient evidence to hold that word-structure bears any interesting relation to the structure of concepts.

A variety of inaccurate claims about Gold's Theorem have appeared in the cognitive science literature. I begin by characterizing the logic of this theorem and its proof. I then examine several claims about Gold's Theorem, and I show why they are false. Finally, I assess the significance of Gold's Theorem for cognitive science.

Reverse Compositionality (RC) is the thesis that one understands a complex expression only if one understands its parts. I argue that this thesis is false for natural languages. I then argue that the phenomenon that motivates the thesis is more likely to be a fact about human sentence-processing than linguistic understanding per se. Finally, I argue that RC is not useful in the debates about prototype-style theories of concepts in which it figures heavily.

We examine the pros and cons of color realism, exposing some desiderata on a theory of color: the theory should render colors as scientifically legitimate and correctly individuated, and it should explain how we have veridical color experiences. We then show that these desiderata can by met by treating colors as properties of the special sciences. According to our view, some of the major as properties of the special sciences. According to our view, some of the major disputes in the (...) literature about color -- anti-realism versus dispositionalism versus reductionism -- are not well-founded at this stage of scientific inquiry. Our account of color is designed to be of use in the sciences and as such is driven largely by considerations of what the various sciences need in order to proceed appropriately. We argue that a scientific theory of colors need not regard colors as anything more than high-level statistical constructs built out of correlations between color experiences and other phenomena.

The empirical nature of our understanding of language is explored. I first show that there are several important and different distinctions between tacit and accessible awareness. I then present empirical evidence concerning our understanding of language. The data suggests that our awareness of sentence-meanings is sometimes merely tacit according to one of these distinctions, but is accessible according to another. I present and defend an interpretation of this mixed view. The present project is shown to impact on several diverse areas, (...) including inferential role semantics and holism, the nature of learning, and the role of linguistics in the law. (shrink)

Famously, scientific theories are underdetermined by their evidence. This occurs in the factor analytic model, which is often used to connect concrete data to hypothetical notions. After introducing FA, three general topics are addressed. Underdetermination: the precise reasons why FA is underdetermined illuminates various claims about underdetermination, abduction, and theoretical terms. Uncertainties: FA helps distinguish at least four kinds of uncertainties. The prevailing practice, often encoded in statistical software, is to ignore the most difficult kinds, which are essential to FA's (...) underdetermination. What to do: some suggestions for dealing with these hardest types of uncertainty are offered. (shrink)

Following Aristotle (who himself was following Parmenides), philosophers have appealed to the distributional reflexes of expressions in determining their semantic status, and ultimately, the nature of the extra-linguistic world. This methodology has been practiced throughout the history of philosophy; it was clarified and made popular by the likes of Zeno Vendler and J.L. Austin, and is realized today in the toolbox of linguistically minded philosophers. Studying the syntax of natural language was fueled by the belief that there is a conceptually (...) tight connection between the syntax of our language and its semantics, and the belief that there is a similarly tight connection between the semantics of our language and metaphysical facts about the world. We are less confident than our colleagues about the relation syntax has to semantics and metaphysics. In particular, we do not believe that the current status of theoretical syntax (or semantics or metaphysics) provides much support for either of the above two beliefs. We will illustrate our view with a case study regarding the status of complex demonstratives. We will show that a recent and particularly subtle syntactically based argument for the semantic/metaphysical status of complex demonstratives does not in fact show what semantic category complex demonstratives are..

A common assumption in metaphysics and the philosophy of language is that the general structure of language displays the general metaphysical structure of the things we talk about. But expressions can easily be imperfect representations of what they are about. After clarifying this general point, I make a case study of a recent attempt to semantically analyze the nature of knowledge-how. This attempt fails because there appears to be no plausible bridge from the linguistic structure of knowledge-how reports to knowledge-how (...) itself. I then gesture at some other places where the connection between linguistics and metaphysics is commonly, but illegitimately, assumed. (shrink)

Methodological dualism in linguistics occurs when its theories are subjected to standards that are inappropriate for them qua scientific theories. Despite much opposition, methodological dualism abounds in contemporary thinking. In this paper, I treat linguistics as a scientific activity and explore some instances of dualism. By extracting some ubiquitous aspects of scientific methodology from its typically quantitative expression, I show that two recent instances of methodologically dualistic critiques of linguistics are ill-founded. I then show that there are nonetheless some divergences (...) between linguistic and other ordinary scientific methods, reflecting yet a third instance of methodological dualism. (shrink)

This paper explores speakers'' epistemic access to the semanticand syntactic features of sentences of their language. I argue that there is evidence that ceteris paribus, the actual semantic features of sentences of a language are accessible as such by typical speakers of that language.I then explore various linguistic, cognitive, and epistemic consequences of this position.

This article reviews some linguistic and philosophical work in lexical semantics. In Section 1, the general methods of lexical semantics are explored, with particular attention to how semantic features of verbs are associated with grammatical patterns. In Section 2, philosophical consequences and issues arising from this sort of research is reviewed.

This paper responds to Philipona & O’Regan (2006), which attempts to account for certain color phenomena by appeal to singularities in the space of “accessible information” in the light striking the retina. Three points are discussed. First, it is unclear what the empirical significance/import is of the mathematical analysis of the data regarding the accessible information in the light. Second, the singularity index employed in the study is both mathematically and empirically faulty. Third, the connection drawn between their findings and (...) some data from the World Color Survey is lacking in quantitative analysis in places where it is needed. The difficulties raised prevent Philipona & O’Regan’s conclusions from being accepted. (shrink)

This paper motivates using explicit methods in linguistics by attempting to estimate the size of a linguistic data set. Such estimations are difficult because redundant data can easily pad the data set. To address this, I offer some explicit operationalizations of the data and their features. But for linguistic data, negative associations don’t indicate true redundancy, and yet for many measures they can be mathematically impossible to ignore. It is proven that this troublesome phenomenon has positive Lebesgue measure, is monotonically (...) increasing, and that these two features hold robustly in four different ways. (shrink)

Gareth Evans proposes that there are semantic natural kinds of words. In his development of this theory,he argues for two constraints on the identification of these kinds. I argue that neither of these constraints are justified. Furthermore,my argument against Evans' second constraint constitutes a direct argument for the existence of semantic natural kinds,something Evans himself never offers. I conclude by sketching some positive details of a more plausible theory of semantic natural kinds.

Keith Donnellan (1931 – ) began his studies at the University of Maryland, and earned his Bachelor’s degree from Cornell University. He stayed on at Cornell, earning a Master’s and a PhD in 1961. He also taught at there for several years before moving to UCLA in 1970, where he is currently Emeritus Professor of Philosophy. Donnellan’s work is mainly in the philosophy of language, with an emphasis on the connections between semantics and pragmatics. His most influential work was his (...) 1966 paper “Reference and Definite Descriptions”. In this paper, he challenges the canonical view, due to Bertrand Russell, about definite descriptions. Russell had argued that the proper semantic treatment of a definite description such as “the present king of France” was quantificational. Thus, a sentence like “the present king of France is bald” should be analyzed as “There exists one and only one entity x that is the present king of France, and x is bald”. Donnellan argues that in natural languages, there are actually two different kinds of uses of definite descriptions. Russell’s analysis picks out the “attributive” use of definite descriptions. When we use a definite description (“the F”) this way, we mean to make statements about the unique entity x that is F. However, Donnellan notes that we also sometimes use definite descriptions “referentially” to pick out a given entity and say something about it. To see this, imagine you are at a party where virtually everyone is drinking beer. However, you and your friend are observing a man in a corner of the room holding a martini glass. Unbeknownst to you, the man’s glass is filled with water. You turn to your friend and ask, “who is the man drinking a martini?” Suppose further that your friend knows that the man in question is Fred and that Fred’s glass is filled with water. According to the Russellian attributive analysis, such a question would amount to asking for the identity of the one and only one man drinking a martini. But the presupposition that there is a man drinking a martini is false, and so there should be no answer to the question.. (shrink)

In this paper, I examine William Whewell’s (1794–1866) ‘Discoverer’s Induction’, and argue that it 21 supplies a strikingly accurate characterization of the logic behind many statistical methods, exploratory 22 data analysis (EDA) in particular. Such methods are additionally well-suited as a point of evaluation of 23 Whewell’s philosophy since the central techniques of EDA were not invented until after Whewell’s death, 24 and so couldn’t have influenced his views. The fact that the quantitative details of some very general 25 methods (...) designed to suggest hypotheses would so closely resemble Whewell’s views of how theories 26 are formed is, I suggest, a strongly positive comment on these views.
