Among the cognitive capacities of evolved creatures is the capacity to represent. Theories in cognitive neuroscience typically explain our manifest representational capacities by positing internal representations, but there is little agreement about how these representations function, especially with the relatively recent proliferation of connectionist, dynamical, embodied, and enactive approaches to cognition. In this talk I sketch an account of the nature and function of representation in cognitive neuroscience that couples a realist construal of representational vehicles with a pragmatic account of (...) mental content. I call the resulting package a deflationary account of mental representation and I argue that it avoids the problems that afflict competing accounts. (shrink)

Introduction: representationalismMost theorists of cognition endorse some version of representationalism, which I will understand as the view that the human mind is an information-using system, and that human cognitive capacities are representational capacities. Of course, notions such as ‘representation’ and ‘information-using’ are terms of art that require explication. As a first pass, representations are “mediating states of an intelligent system that carry information” (Markman and Dietrich 2001, p. 471). They have two important features: (1) they are physically realized, and so (...) have causal powers; (2) they are intentional, in other words, they have meaning or representational content. This presumes a distinction between a representational vehicle—a physical state or structure that has causal powers and is responsible for producing behavior—and its content. Consider the following characterization of a device that computes the addition functionReaders will recognize the similarity t. (shrink)

Much of computational cognitive science construes human cognitive capacities as representational capacities, or as involving representation in some way. Computational theories of vision, for example, typically posit structures that represent edges in the distal scene. Neurons are often said to represent elements of their receptive fields. Despite the ubiquity of representational talk in computational theorizing there is surprisingly little consensus about how such claims are to be understood. The point of this chapter is to sketch an account of the nature (...) and function of representation in computational cognitive models. (shrink)

A common kind of explanation in cognitive neuroscience might be called functiontheoretic: with some target cognitive capacity in view, the theorist hypothesizes that the system computes a well-defined function (in the mathematical sense) and explains how computing this function constitutes (in the system’s normal environment) the exercise of the cognitive capacity. Recently, proponents of the so-called ‘new mechanist’ approach in philosophy of science have argued that a model of a cognitive capacity is explanatory only to the extent that it reveals (...) the causal structure of the mechanism underlying the capacity. If they are right, then a cognitive model that resists a transparent mapping to known neural mechanisms fails to be explanatory. I argue that a functiontheoretic characterization of a cognitive capacity can be genuinely explanatory even absent an account of how the capacity is realized in neural hardware. (shrink)

The computational theory of mind construes the mind as an information-processor and cognitive capacities as essentially representational capacities. Proponents of the view claim a central role for representational content in computational models of these capacities. In this paper I argue that the standard view of the role of representational content in computational models is mistaken; I argue that representational content is to be understood as a gloss on the computational characterization of a cognitive process.Keywords: Computation; Representational content; Cognitive capacities; Explanation.

Externalism about the mind holds that the explanation of our representational capacities requires appeal to mental states that are individuated by reference to features of the environment. Externalists claim that ‘narrow’ taxonomies cannot account for important features of psychological explanation. I argue that this claim is false, and offer a general argument for preferring narrow taxonomies in psychology.

Representationalism, in its most widely accepted form, is the view that the human mind is an information-using system, and that human cognitive capacities are to be understood as representational capacities. This chapter distinguishes several distinct theses that go by the name "representationalism," focusing on the view that is most prevalent in cogntive science. It also discusses some objections to the view and attempts to clarify the role that representational content plays in cognitive models that make use of the notion of (...) representation. (shrink)

It has recently been argued that the success of the connectionist program in cognitive science would threaten folk psychology. I articulate and defend a "minimalist" construal of folk psychology that comports well with empirical evidence on the folk understanding of belief and is compatible with even the most radical developments in cognitive science.

Nicholas Shea offers Varitel Semantics as a naturalistic account of mental content. I argue that the account secures determinate content only by appeal to pragmatic considerations, and so it fails to respect naturalism. But that is fine, because representational content is not, strictly speaking, necessary for explanation in cognitive science. Even in Shea’s own account, content serves only a variety of heuristic functions.

The “top-down” and “bottom-up” approaches have been thought to exhaust the possibilities for doing cognitive neuroscience. We argue that neither approach is likely to succeed in providing a theory that enables us to understand how cognition is achieved in biological creatures like ourselves. We consider a promising third way of doing cognitive neuroscience, what might be called the “neural dynamic systems” approach, that construes cognitive neuroscience as an autonomous explanatory endeavor, aiming to characterize in its own terms the states and (...) processes responsible for brain-based cognition. We sketch the basic motivation for the approach, describe a particular version of the approach, so-called ‘Dynamic Causal Modeling’ (DCM), and consider a concrete example of DCM. This third way, we argue, has the potential to avoid the problems that afflict the other two approaches. (shrink)

Mohan Matthen has failed to understand the position I develop and defend in “How to Think about Mental Content.” No doubt some of the fault lies with my exposition, though Matthen often misconstrues passages that are clear in context. He construes clarifications and elaborations of my argument to be “concessions.” Rather than dwell too much on specific misunderstandings of my explanatory project and its attendant claims, I will focus on the main points of disagreement.RepresentationalismMy project in the paper is to (...) argue for a particular construal of the role of representational content in computational models of cognition. The view is committed to two kinds of representational content—mathematical content, which characterizes the mathematical function computed by a device and subsumes both biological and artifactual computers, and cognitive content. The latter is determined in part by external, so-called ‘naturalistic’ factors (for example, visual mechanisms represent such distal pro. (shrink)

Ever since Berkeley discussed the problem at length in his Essay Toward a New Theory of Vision, theorists of vision have attempted to explain why the moon appears larger on the horizon than it does at the zenith. Prevailing opinion has it that the contemporary perceptual psychologists Kaufman and Rock have finally explained the illusion. This paper argues that Kaufman and Rock have not refuted a Berkeleyan account of the illusion, and have over-interpreted their own experimental results. The moon illusion (...) remains unexplained, and a Berkeleyan account is still a contender. (shrink)

Comments on Karen Neander's A Mark of the Mental.

In the philosophy of perception, representationalism is the view that all phenomenological differences among mental states are representational differences, in other words, differences in content. In this paper I defend an alternative view which I call external sortalism, inspired by traditional adverbialism, and according to which experiences are not essentially representational. The central idea is that the external world serves as a model for sorting, conceptualizing, and reasoning surrogatively about perceptual experience. On external sortalism, contents are construed as a kind (...) of gloss on experiences themselves. We can retain what is attractive about representationalism, namely, that perceptual experiences can be evaluated for accuracy, without problematic commitment to the idea that they bear a substantive, representational relation to external objects and properties and that this relation determines the phenomenal character of experience.

Successful sports teams are able to adopt what is known as the 'we-perspective,' forming intentions and making decisions, somewhat as a unified mind does, to achieve their goals. In this paper I consider what is involved in establishing and maintaining the we-perspective on a racing sailboat. I argue that maintaining the we-perspective contributes to the success of the boat in at least two ways: (1) it facilitates the smooth execution of joint action; and (2) it increases the chance that individual (...) crew members will exert their best effort in fulfilling their particular roles on the boat.

Steve Stich used to be an eliminativist. As far as I can tell, he renounced eliminativism about the time that he moved from the west to the east pole.1 Stich was right to reject eliminativism, though I am not convinced that he rejected it for the right reasons. Stich 1983 contains a comprehensive attack on representational content, a central feature of both folk psychology and the Representational Theory of Mind, the leading philosophical construal of scientific psychology. Stich’s current position on (...) the role of content in psychological explanation is not entirely clear. One of my aims in this chapter is simply to invite Stich to clarify his views on representational content; the question that forms the title of this chapter is therefore addressed directly to Stich. I begin by sketching his original anti-content argument. I then trace some later developments in his thinking about content. I argue that content does play an important role in scientific psychology, for precisely the reasons that Stich identified in his original argument against content. I conclude with some general remarks on eliminativism. (shrink)

Comments on Karen Neander's A Mark of the Mental.

Stephen Stich has argued that psychological theories that instantiate his Syntactic Theory of Mind are to be preferred to content-based or representationalist theories, because the former can capture and explain a wider range of generalizations about cognitive processes than the latter. Stich's claims about the relative merits of the Syntactic Theory of Mind are unfounded. Not only is it false that syntactic theories can capture psychological generalizations that content-based theories cannot, but a large class of behavioral regularities, readily explained by (...) content-based theories, appear to be beyond their explanatory reach.

In the appendix to Psychosemantics, entitled ‘Why There Still has to be a Language of Thought,’ Jerry Fodor offers several arguments for the language of thought thesis. The LOT, as articulated by Fodor, is a thesis about propositional attitudes. It comprises the following two claims: propositional attitudes are relations to meaning-bearing tokens — for example, to believe that P is to bear a certain relation to a token of a symbol which means that P; and the representational tokens in question (...) are quasi-linguistic — in particular, they have the constituent structure appropriate to a language.

“Naturalistic” semantic theories attempt to specify, in nonintentional and nonsemantic terms, a sufficient condition for a mental representation’s having a particular meaning. Such theories have trouble accounting for the possibility of representational error. In his latest book, Robert Cummins traces the problem to the fact that the theories currently on offer identify the meaning of a representation with certain features of its use. Only a theory that takes meaning to be an intrinsic feature of a representation, Cummins argues, can both (...) accommodate representational error and play a genuinely explanatory role in an account of rational capacities. In the second half of the book he develops and defends a proposal that he calls the “picture theory of representation.”. (shrink)

Noam Chomsky and Frances Egan argue that David Marr.

“There’s no disputing about taste.” That’s got a nice ring to it, but it’s not quite the ring of truth. While there’s definitely something right about the aphorism – there’s a reason why it is, after all, an aphorism, and why its utterance tends to produce so much nodding of heads and muttering of “just so” and “yes, quite” – it’s surprisingly difficult to put one’s finger on just what the truth in the neighborhood is, exactly. One thing that’s pretty (...) clear is that what’s right about the aphorism, that there’s no disputing about taste, isn’t that there’s no disputing about taste. There’s heaps of disputing about taste. People engage in disputes about which movies, music, paintings, literature, meals, furniture, architectural styles, etc. are good, beautiful, tasty, fun, elegant, ugly, disgusting, etc. all the time. This is obvious to anyone who has watched dueling-movie-critics shows, read theater reviews, or negotiated with a group or partner about which movie or restaurant to go to, or which sofa or painting to put in the living room. It takes great care and good aim to fling a brick without hitting somebody who’s engaged in a dispute about taste. (shrink)

Problems about the accidental properties of properties motivate us--force us, I think--not to identify properties with the sets of their instances. If we identify them instead with functions from worlds to extensions, we get a theory of properties that is neutral with respect to disputes over counterpart theory, and we avoid a problem for Lewis's theory of events. Similar problems about the temporary properties of properties motivate us--though this time they probably don't force us--to give up this theory as well, (...) and to identify properties with functions from world, time pairs to extensions. Again, the replacement theory is neutral with respect to a metaphysical dispute that the old theory (arguably) forces us to take a stand on--the dispute over whether objects have temporal parts. It also allows us to give a smoother semantics for predication, to better accommodate our intuitions about which objects temporary properties are properties of, and to make temporally self-locating beliefs genuinely self -locating.

Responsible research and innovation has come to represent a change in the relationship between science, technology and society. With origins in the democratisation of science, and the inclusion of ethical and societal aspects in research and development activities, RRI offers a means of integrating society and the research and innovation communities. In this article, we frame RRI activities through the lens of layers of science and technology governance as a means of characterising the context in which the RRI activity is (...) positioned and the goal of those actors promoting the RRI activities in shaping overall governance patterns. RRI began to emerge during a time of considerable deliberation about the societal and governance challenges around nanotechnology, in which stakeholders were looking for new ways of integrating notions of responsibility in nanotechnology research and development. For this reason, this article focuses on nanotechnology as the site for exploring the evolution and growth of RRI. (shrink)

Ludwig Wittgenstein famously compares units of language to games, but his pupil Rush Rhees finds that analogy limiting. Unlike uses of language, says Rhees, games are not part of a larger whole and do not have a point, which means that games, unlike language, cannot lead to growth in understanding. Treating language like a game, according to Rhees, is characteristic of sophistry. But this paper claims that sophistry is not like playing a game but like playing the spoilsport. Wittgenstein’s fluid (...) understanding of the distinction between games and non-game play allows his conception of language-games to avoid the charge of sophistry. (shrink)

Issues of responsibility in the world of nanotechnology are becoming explicit with the emergence of a discourse on ‘responsible development’ of nanoscience and nanotechnologies. Much of this discourse centres on the ambivalences of nanotechnology and of promising technology in general. Actors must find means of dealing with these ambivalences. Actors’ actions and responses to ambivalence are shaped by their position and context, along with strategic games they are involved in, together with other actors. A number of interviews were conducted with (...) industrial actors with the aim of uncovering their ethical stances towards responsible development of nanotechnology. The data shows that standard repertoires of justification of nanotechnological development were used. Thus, the industrial actors fell back on their position and associated responsibilities. Such responses reinforce a division of moral labour in which industrial actors and scientists can focus on the progress of science and technology, while other actors, such as NGOs, are expected to take care of broader considerations, such as ethical and social issues.
