The celebrated "Twin Earth" arguments of Hilary Putnam (1975) and Tyler Burge (1979) aim to establish that some intentional states logically depend on facts external to the subjects of those states. Ascriptions of states of these kinds to a thinker entail that the thinker's environment is a certain way. It is not possible that the thinker could be in those very intentional states unless the environment is that way...

Alvin Plantinga's evolutionary argument against naturalism makes the case that the conjunction of evolutionary theory and naturalism cannot be rationally believed, as, if both evolutionary theory and naturalism were true, it would be highly unlikely that our cognitive faculties are reliable. I present Plantinga's evolutionary argument against naturalism and survey a theory of meaning espoused by Robert Brandom, known as semantic inferentialism. I argue that if one accepts semantic inferentialism, as it is developed by Brandom, then Plantinga's motivation for the (...) evolutionary argument against naturalism is undermined. (shrink)

Where does the mind stop and the rest of the world begin? The question invites two standard replies. Some accept the demarcations of skin and skull, and say that what is outside the body is outside the mind. Others are impressed by arguments suggesting that the meaning of our words "just ain't in the head", and hold that this externalism about meaning carries over into an externalism about mind. We propose to pursue a third position. We advocate a very different (...) sort of externalism: an _active externalism_, based on the active role of the environment in driving cognitive processes.

Wilfrid Sellars ranks as one of the leading critics of empiricism—a philosophical approach to knowledge that seeks to ground it in human sense experience. Robert Brandom clarifies what Sellars had in mind when he talked about moving analytic philosophy from its Humean to its Kantian phase and why such a move might be of crucial importance today.

Robert Brandom's latest book, the product of his John Locke lectures in Oxford in 2006, is a return to the philosophy of language and is easily read as a continuation and development of the views defended in Making it Explicit. The text of the lectures is presented much as they were delivered, but it contains an ‘Afterword’ of more than 30 pages which responds to questions raised when he gave the lectures, and also when they were subsequently delivered in Prague (...) the following year. The published text also contains relatively technical appendices to two of the lectures.The individual lectures engage with some important and difficult issues, often ones that were explored in detail in the earlier book. However, these discussions are located within a broader meta-philosophical context, and it says something about the abstract and difficult character of these views that they provide the main subject matter of the Afterword. This framework affects how we should understand the relations between this book and Making It Explicit too. Although most of the detailed discussions happily belong within the general project of the earlier book, they are offered as illustrations of a framework that is independent of this project. Indeed, Brandom suggests that defenders of the semantic views of David Lewis, for example, could embrace his main message as well as those who favour Brandom's own form of pragmatism.Neo-pragmatist philosophers such as Brandom's teacher, Richard Rorty, often present themselves as rejecting the analytic tradition in philosophy. When Brandom describes the ‘pragmatist challenge’ to the ‘classical project of analysis’, he appeals to the criticisms found in the work of Wittgenstein and Sellars that are often appealed to by the critics of the analytic tradition. The message of the new book is that the views he has built on this …. (shrink)

Extended Cognition (EC) hypothesizes that there are parts of the world outside the head serving as cognitive vehicles. One criticism of this controversial view is the problem of “cognitive bloat” which says that EC is too permissive and fails to provide an adequate necessary criterion for cognition. It cannot, for instance, distinguish genuine cognitive vehicles from mere supports (e.g. the Yellow Pages). In response, Andy Clark and Mark Rowlands have independently suggested that genuine cognitive vehicles are distinguished from supports in (...) that the former have been “recruited,” i.e. they are either artifacts, or, products of evolution. I argue against this proposal. There are counter examples to the claim that “Teleological” EC is either necessary or sufficient for cognition. Teleological EC conflates different types of scientific projects, and inherits content externalism’s alienation from historically impartial cognitive science. (shrink)

An alarming number of philosophers and cognitive scientists have argued that mind extends beyond the brain and body. This book evaluates these arguments and suggests that, typically, it does not. A timely and relevant study that exposes the need to develop a more sophisticated theory of cognition, while pointing to a bold new direction in exploring the nature of cognition Articulates and defends the “mark of the cognitive”, a common sense theory used to distinguish between cognitive and non-cognitive processes Challenges (...) the current popularity of extended cognition theory through critical analysis and by pointing out fallacies and shortcoming in the literature Stimulates discussions that will advance debate about the nature of cognition in the cognitive sciences.

Tools and technologies expand our capacities, including our cognitive capacities. Microscopes extend our perceptual capacities. Notebooks extend the natural limits of memory. These facts are important, for all that they are obvious. The extended cognition hypothesis wants more. Some external devices and processes are literal parts of cognitive processes themselves. When there is fast and reliable access to external data or processes, then the cognitive processes that occur uncontroversially inside the brain literally and controversially extend out into the world to (...) incorporate external structures or processes. Retrieval of an address from memory and retrieval of the same information from a notebook can both be fully cognitive processes involving fully cognitive representations. So say the proponents of extended cognition.It is an attractive metaphor. But is there any good reason to take it as literal truth? Adams and Aizawa argue that the debate on extended cognition implicates an …. (shrink)

David Sloan Wilson has recently revived the idea of a group mind as an application of group selectionist thinking to cognition. Central to my discussion of this idea is the distinction between the claim that groups have a psychology and what I call the social manifestation thesis-a thesis about the psychology of individuals. Contemporary work on this topic has confused these two theses. My discussion also points to research questions and issues that Wilson's work raises, as well as their connection (...) to externalist conceptions of the mind familiar since the work of Putnam and Burge.

I consider two threats to the idea that on-line intelligent behaviour (the production of fluid and adaptable responses to ongoing sensory input) must or should be explained by appeal to neurally located representations. The first of these threats occurs when extra-neural factors account for the kind of behavioural richness and flexibility normally associated with representation-based control. I show how this anti-representational challenge can be met, if we apply the thought that, to be a representational system, an action-oriented neural system must (...) not only be the source of at least some of the observed behavioural richness and flexibility, it must also feature two architectural traits, namely arbitrariness and homuncularity. Unfortunately, however, this solution opens the door to our second threat to representation. The homuncularity condition will not be met by any system in which the causal contribution of each component is massively context-sensitive and variable over time. I end by discussing the empirical bet that biological nervous systems will not exhibit this style of causation. (shrink)

Extended cognition is the view that some cognitive processes extend beyond the brain. One prominent strategy of arguing against extended cognition is to offer necessary conditions on cognition and argue that the proposed extended processes fail to satisfy these conditions. I argue that this strategy is misguided and fails to refute extended cognition. I suggest a better way to evaluate the case for extended cognition that should be acceptable to all parties, captures the intuitiveness of previous objections, and avoids the (...) problems with the strategy of offering necessary conditions on cognition. I conclude that extended cognition theorists have failed to establish the truth of extended cognition. (shrink)

This chapter discusses the plausibility of the criticism against the thesis that external factors causally influence cognition and that they are, consequently, partly constitutive of cognition. The discussion should not be taken as implicitly proposing that the opposite theory is true, although the works of Adams and Aizawa suggest that they are defending internalism. This can be attributed to the fact that systems are, by definition, bounded; one must make assumptions about systems in developing cognitive models. This chapter defends the (...) position that metaphysical considerations should play no role in deciding how to model cognition. It further explains how there is no basis for a general fact of the matter about determining what is and what is not a cognitive system. (shrink)

Recently internalists have mounted a counter-attack on the attempt to redefine the bounds of cognition. The counter-attack is aimed at a radical project which I call "cognitive integration," which is the view that internal and external vehicles and processes are integrated into a whole. Cognitive integration can be defended against the internalist counter arguments of Adams and Aizawa (A&A) and Rupert. The disagreement between internalists and integrationists is whether the manipulation of external vehicles constitutes a cognitive process. Integrationists think that (...) they do, typically for reasons to do with the close coordination and causal interplay between internal and external processes. The internalist criticisms of the manipulation thesis fail because they misconstrue the nature of manipulation, ignore the hybrid nature of cognition, and take the manipulation thesis to be dependent upon a weak parity principle.

Philosophical accounts of the constitution relation have been explicated in terms of synchronic relations between higher‐ and lower‐level entities. Such accounts, I argue, are temporally austere or impoverished, and are consequently unable to make sense of the diachronic and dynamic character of constitution in dynamical systems generally and dynamically extended cognitive processes in particular. In this paper, my target domain is extended cognition based on insights from nonlinear dynamics. Contrariwise to the mainstream literature in both analytical metaphysics and extended cognition, (...) I develop a nonstandard, alternative conception of constitution, which I call “diachronic process constitution”. It will be argued that only a diachronic and dynamical conception of constitution is consistent with the nature of constitution in distributed cognitive processes. (shrink)

A critique of the hypothesis of extended cognition.

That about sums up what is wrong with Clark's view.

The ‘causal-constitution’ fallacy, the ‘cognitive bloat’ worry, and the persisting theoretical confusion about the fundamental difference between the hypotheses of embedded (HEMC) and extended (HEC) cognition are three interrelated worries, whose common point—and the problem they accentuate—is the lack of a principled criterion of constitution. Attempting to address the ‘causal-constitution’ fallacy, mathematically oriented philosophers of mind have previously suggested that the presence of non-linear relations between the inner and the outer contributions is sufficient for cognitive extension. The abstract idea of (...) non-linearity, however, can be easily misunderstood and has, in the past, led to incorrect and counterintuitive conclusions about what may count as part of one’s overall cognitive system. In order to prevent any further mistakes I revisit dynamical systems theory to study the nature of the continuous mutual interactions that give rise to the aforementioned non-linear relations. Moreover, focusing on these interactions will allow us to provide two distinct arguments in support of the ontological postulation of extended cognitive systems, as well as an objective criterion of constitution. Accordingly, I put forward a version of HEC that treats continuous mutual interactions (and the resultant non-linear relations) not just as sufficient but also as necessary for cognitive extension. Such a qualified version of HEC may exclude certain alleged cases of cognitive extension where the agent does not mutually interact with his artifacts (e.g., shopping lists and directory services), but it is immune both to the ‘causal-constitution’ fallacy and the ‘cognitive bloat’ worry, and it can be sharply distinguished from HEMC.
