According to the thesis of semantic underdetermination, most sentences of a natural language lack a definite semantic interpretation. This thesis supports an argument against the use of natural language as an instrument of thought, based on the premise that cognition requires a semantically precise and compositional instrument. In this paper we examine several ways to construe this argument, as well as possible ways out for the cognitive view of natural language in the introspectivist version defended by Carruthers. Finally, we sketch a view of the role of language in thought as a specialized tool, showing how it avoids the consequences of semantic underdetermination.

The language sciences—Linguistics, Psycholinguistics, and Computational Linguistics—have not been broadly represented at the Cognitive Science Society meetings of the past 30 years, but they are an important part of the heart of cognitive science. This article discusses several major themes that have dominated the controversies and consensus in the study of language and suggests the most pressing issues of the future. These themes include differences among the language science disciplines in their view of numbers and symbols and of modular and distributed cognition, and the need for an increasing prominence of questions concerning language and the brain.

Consider the idea that a natural language like English is in the first instance incorporated into the system of representation one thinks with. This ‘incorporation’ view is compared with a translation or ‘decoding’ view of communication. Compositional semantics makes sense only given the implausible decoding view.

Carruthers argues that natural language is the medium of non-domain-specific thought in humans. The general idea is that a certain type of thinking is conducted in natural language. It’ not exactly clear, however, what type of thinking this is. I suggest two different ways of interpreting Carruthers’ thesis on this point and argue that neither of them squares well with central-process modularism.

This article deals with the relationship between language and thought, focusing on the question of whether language can be a vehicle of thought, as, for example, Peter Carruthers has claimed. We develop and examine a powerful argument—the "argument from explicitness"—against this cognitive role of language. The premises of the argument are just two: (1) the vehicle of thought has to be explicit, and (2) natural languages are not explicit. We explain what these simple premises mean and why we should believe they are true. Finally, we argue that even though the argument from explicitness shows that natural language cannot be a vehicle of thought, there is a cognitive function for language.

Do we conduct our conscious propositional thinking in natural language? Or is such language only peripherally related to human conscious thought-processes? In this paper I shall present a partial defence of the former view, by arguing that the only real alternative is eliminativism about conscious propositional thinking. Following some introductory remarks, I shall state the argument for this conclusion, and show how that conclusion can be true. Thereafter I shall defend each of the three main premises in turn.

This paper explores a variety of different versions of the thesis that natural language is involved in human thinking. It distinguishes amongst strong and weak forms of this thesis, dismissing some as implausibly strong and others as uninterestingly weak. Strong forms dismissed include the view that language is conceptually necessary for thought (endorsed by many philosophers) and the view that language is _de facto_ the medium of all human conceptual thinking (endorsed by many philosophers and social scientists). Weak forms include the view that language is necessary for the acquisition of many human concepts, and the view that language can serve to scaffold human thought processes. The paper also discusses the thesis that language may be the medium of _conscious_ propositional thinking, but argues that this cannot be its most fundamental cognitive role. The idea is then proposed that natural language is the medium for non-domain-specific thinking, serving to integrate the outputs of a variety of domain-specific conceptual faculties (or central-cognitive ‘quasi-modules’). Recent experimental evidence in support of this idea is reviewed, and the implications of the idea are discussed, especially for our conception of the architecture of human cognition. Finally, some further kinds of evidence which might serve to corroborate or refute the hypothesis are mentioned. The overall goal of the paper is to review a wide variety of accounts of the cognitive function of natural language, integrating a number of different kinds of evidence and theoretical consideration in order to propose and elaborate the most plausible candidate.

Carruthers suggests that natural language, in the form of inner speech, may be the vehicle of conscious propositional thought, but he argues that its fundamental cognitive role is as the medium of cross-modular thinking, both conscious and nonconscious. I argue that there is no evidence for nonconscious cross-modular thinking and that the most plausible view is that cross-modular thinking, like conscious propositional thinking, occurs only in inner speech.

What is the place of language in human cognition? Do we sometimes think in natural language? Or is language for purposes of interpersonal communication only? Although these questions have been much debated in the past, they have almost dropped from sight in recent decades amongst those interested in the cognitive sciences. Language and Thought is intended to persuade such people to think again. It brings together essays by a distinguished interdisciplinary team of philosophers and psychologists, who discuss various ways in which language may be implicated in human cognition. The editors have provided an introduction which lays out the basic terms and history of the debate, and a consolidated bibliography which will provide a valuable reference resource for all those interested in this area. The volume will be of great interest to all researchers and students interested in language and its place in cognition.
