Argues that belief/desire psychology – and with it a form of first-order access-consciousness – are very widely distributed in the animal kingdom, being shared even by navigating insects. Although the main topic of this chapter is not mental-state consciousness, it serves both to underscore the argument of the previous chapter, and to emphasise how wide is the phylogenetic distance separating mentality per se from phenomenally conscious mentality. On some views, these things are intimately connected. But on the author’s view, they could not be further apart. We share the basic forms of our mental lives even with bees and ants. But we may be unique in the animal kingdom in possessing mental states that are phenomenally conscious.

Works its way through a variety of different accounts of phenomenal consciousness, looking at the strengths and weaknesses of each. At the heart of the chapter is an extended critical examination of first-order representational theories, of the sort espoused by Dretske and Tye, arguing that they are inferior to higher-order representational accounts. Acknowledges as a problem for HOR theories that they might withhold phenomenal consciousness from most other species of animal, but claims that this problem should not be regarded as a serious obstacle to the acceptance of some such theory. Different versions of HOR theory are discussed, and the author’s own account is briefly elaborated and defended.

Implicit and explicit attitudes manifest themselves as distinct and partly dissociable behavioral dispositions. It is natural to think that these differences reflect differing underlying representations. The present article argues that this may be a mistake. Although non-verbal and verbal measures of attitudes often dissociate, this may be because the two types of outcome-measure are differentially impacted by other factors, not because they are tapping into distinct kinds of representation or distinct storage systems. I arrive at this view through closer consideration than is usual of the mechanisms and processes that underlie overt behavior.

Presents and develops what the author takes to be the main argument, both against the most plausible version of first-order representationalist theory of phenomenal consciousness, and in support of his own higher-order perception/dual-content account. The primary goal of the chapter is to lay out the case for saying that dual-content theory provides us with a successful reductive explanation of the various puzzling features of phenomenal consciousness. Also takes up the question whether a first-order theorist can also accept the higher-order analogue contents postulated by dual-content theory, and can thereby obtain all of the advantages of the latter, while retaining their distinctively first-order account of phenomenal consciousness itself. It returns a negative answer.

Shifts focus from conscious experience to conscious thought. It develops a dilemma. Either the use of natural language sentences in ‘inner speech’ is constitutive of thinking, as opposed to being merely expressive of it. Or there may really be no such thing as conscious propositional thinking at all, and eliminativism about conscious thinking is true. While the author makes clear my preference for the first horn of this dilemma, and explains how such a claim could possibly be true, this is not really defended in any depth, and the final choice is left to the reader. Nor does the chapter commit itself to any particular theory of conscious thinking, beyond defending the claim that, in order to count as conscious, a thought must give rise to the knowledge that we are entertaining it in a way that is neither inferential nor interpretative.

This paper argues that a set of questioning attitudes are among the foundations of human and animal minds. While both verbal questioning and states of curiosity are generally explained in terms of metacognitive desires for knowledge or true belief, I argue that each is better explained by a prelinguistic sui generis type of mental attitude of questioning. I review a range of considerations in support of such a proposal and improve on previous characterizations of the nature of these attitudes. I then broaden their explanatory scope to include a number of forms of exploratory search. The paper has three main goals: to characterize the nature of the questioning attitudes, outlining their causal role and type of content; to argue that they are fundamental components of the mind, being widespread among animals and not constructed during ontogeny out of other attitudes; and to suggest that they explain a great deal more behavior than one might think.

This article replies to the main objections raised by the commentators on Carruthers. It discusses the question of what evidence is relevant to the assessment of dispositional higher-order thought theory; it explains how the actual properties of phenomenal consciousness can be dispositionally constituted; it discusses the case of pains and other bodily sensations in non-human animals and young children; it sketches the case for preferring higher-order to first-order theories of phenomenal consciousness; and it replies to some miscellaneous points and objections.

Various dichotomies have been proposed to characterize the nature and development of human mindreading capacities, especially in light of recent evidence of mindreading in infants aged 7 to 18 months. This article will examine these suggestions, arguing that none is currently supported by the evidence. Rather, the data support a modular account of the domain-specific component of basic mindreading capacities. This core component is present in infants from a very young age and does not alter fundamentally thereafter. What alters with development are the interactions between core mindreading and other systems, including executive systems, and forms of learning that do not require radical conceptual change.

This chapter argues that our language faculty can both be a peripheral module of the mind and be crucially implicated in a variety of central cognitive functions, including conscious propositional thinking and reasoning. I also sketch arguments for the view that natural language representations (e.g. of Chomsky's Logical Form, or LF) might serve as a lingua franca for interactions (both conscious and non-conscious) between a number of quasi-modular central systems. The ideas presented are compared and contrasted with the evolutionary proposals made by Derek Bickerton (1990, 1995), who has also argued for the involvement of language in thought. Finally, I propose that it was the evolution of a mechanism responsible for pretend play, circa 40,000 years ago, which led to the explosion of creative culture visible in the fossil record from that time onwards.

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.

This paper argues that navigating insects and spiders possess a degree of mindedness that makes them appropriate (in the sense of “possible”) objects of sympathy and moral concern. For the evidence suggests that many invertebrates possess a belief-desire-planning psychology that is in basic respects similar to our own. The challenge for ethical theory is find some principled way of demonstrating that individual insects do not make moral claims on us, given the widely held belief that some other “higher” animals do make such claims on us.

Carruthers offers a refreshing piece of “substantive philosophy.” Going beyond the limitations of pure analysis, he adopts a methodology which is one part analysis, one part empirical data, and a heavy dose of inference to the best explanation. The overarching goal is to advance the commonsense—yet unfashionable—thesis that natural language is the primary medium of thought, and to defend the related cognitive conception of NL. In particular, Carruthers argues that imaginative phonological representations of “inner speech” are constitutive of conscious thoughts, and that thinking involves operations on such symbols. While there is still a role for mentalese cognition, such thinking is always unconscious, and probably of limited innate conceptual resources. The weak thesis is that, of natural necessity, all conscious propositional thought requires NL. The strong thesis is that, of natural necessity, distinctively human thoughts can only be tokened in natural language—hence even much of our unconscious thinking occurs in English.

This book develops in detail the simple idea that assertion is the expression of belief. In it the author puts forward a version of 'probabilistic semantics' which acknowledges that we are not perfectly rational, and which offers a significant advance in generality on theories of meaning couched in terms of truth conditions. It promises to challenge a number of entrenched and widespread views about the relations of language and mind. Part I presents a functionalist account of belief, worked through a modified form of decision theory. In Part II the author generates a theory of meaning in terms of 'assertibility conditions', whereby to know the meaning of an assertion is to know the belief it expresses.

Contemporary debates in epistemology devote much attention to the nature of knowledge, but neglect the question of its sources. This book focuses on the latter, especially on the question of innateness. Carruthers' aim is to transform and reinvigorate contemporary empiricism, while also providing an introduction to a range of issues in the theory of knowledge. He gives a lively presentation and assessment of the claims of classical empiricism, particularly its denial of substantive a priori knowledge and of innate knowledge. He argues that we would be right to reject the substantive a priori but not innateness, and then presents a novel account of the main motivation behind empiricism, which leaves contemporary empiricists free to accept innate knowledge and concepts. Carruthers closes with a discussion of scepticism, arguing that acceptance of innate concepts may lead to a decisive resolution of the problem in favor of realism.

This paper sketches a solution to a problem which has been emphasized by Fodor. This is the problem of how to explain distinctively-human flexible cognition in modular terms. There are three aspects to the proposed account. First, it is suggested that natural language sentences might serve to integrate the outputs of a number of conceptual modules. Second, a creative sentence-generator, or supposer, is postulated. And third, it is argued that a set of principles of inference to the best explanation can be constructed from already-extant aspects of linguistic testimony and discourse interpretation. Most importantly, it is suggested that the resulting architecture should be implementable in ways that are computationally tractable.
