Objections to Extended Cognition

Extended mind remains a provocative approach to cognition and mentality. However, both those for and against this approach have tacitly accepted that cognition or mentality can be understood in terms of those sub personal processes ongoing during some task. I label this a process view of cognition (PV). Using Wittgenstein’s philosophical approach, I argue that proponents of extended mind should reject PV and instead endorse a ‘wide view’ of mentality. This wide view clarifies why the hypothesis of extended mind (HEM) (...) is incoherent. However, this view also indicates why the hypothesis of extended cognition (HEC) could be true. (shrink)

Since the publication of Clark and Chalmers' Extended Mind paper, the central claims of that paper, viz. the thesis that cognitive processes and cognitive or mental states extend beyond the brain and body, have been vigorously debated within philosophy of mind and philosophy of cognitive science. Both defenders and detractors of these claims have since marshalled an impressive battery of arguments for and against “active externalism.” However, despite the amount of philosophical energy expended, this debate remains far from settled. We (...) argue that this debate can be understood as answering two metaphysical questions. Yet prominent voices within the debate have assumed that there is a tight relationship between these two questions such that one question can be answered via the other. We defend an alternative ‘wide’ view, whereby mentality is understood as constituted by wide social and cultural factors. Our wide view entails that the two metaphysical questions are separate and should be kept distinct. This suggests that active externalism as understood by prominent voices within that debate requires dissolution, rather than solution. However, if the debate were instead understood as only focusing on the second of the two questions, then there could be a possible future for this debate. (shrink)

I critically examine Adams and Garrison’s proposed necessary condition for the mark of the cognitive (Adams and Garrison in Minds Mach 23(3):339–352, 2013). After a brief presentation of their position, I argue not only that their proposal is in need of additional support, but also that it is too restrictive.

In Supersizing the Mind: Embodiment, Action, and Cognitive Extension (Clark, 2008), Andy Clark bolsters his case for the extended mind thesis and casts a critical eye on some related views for which he has less enthusiasm. To these ends, the book canvasses a wide range of empirical results concerning the subtle manner in which the human organism and its environment interact in the production of intelligent behavior. This fascinating research notwithstanding, Supersizing does little to assuage my skepticism about the hypotheses (...) of extended cognition and extended mind. In particular, Supersizing fails to make the case for the extended view as a revolutionary thesis in the theoretical foundations of cognitive science. (shrink)

The aim of this article is to show that externalist accounts of cognition such as Clark and Chalmers' (1998) “active externalism” lead to an explosion of knowledge that is caused by online resources such as Wikipedia and Google. I argue that externalist accounts of cognition imply that subjects who integrate mobile Internet access in their cognitive routines have millions of standing beliefs on unexpected issues such as the birth dates of Moroccan politicians or the geographical coordinates of villages in southern (...) Indonesia. Although many externalists propose criteria for the bounds of cognition that are designed to avoid this explosion of knowledge, I argue that these criteria are flawed and that active externalism has to accept that information resources such as Wikipedia and Google constitute extended cognitive processes.

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)

For more than one decade, Andy Clark has defended the now-famous extended mind thesis, the idea that cognitive processes leak into the world. In this paper I analyse Clark’s theoretical justification for the thesis: explanatory simplicity. I argue that his way of justifying the thesis leads into contradiction, either at the level of propositional attitude ascriptions or at the theoretical level. I evaluate three possible strategies of dealing with this issue, concluding that they are all likely to fail and that (...) therefore, as regards explanatory simplicity, the burden of proof is on Clark’s side. The paper divides into two main sections: in “Simplicity and Coherence”, I define the two concepts that are important in this context (simplicity and explanatory coherence). In “How to Cope with Coherence”, these two concepts are applied to the central thought experiment, the Inga/Otto case. It will be shown that justifying the extended mind thesis by reference to simplicity may cause trouble, because ‘extended’ behavioural descriptions are likely to yield rather complicated explanations.

There is no Argument that the Mind Extends On the basis of two argumentative examples plus their 'parity principle', Clark and Chalmers argue that mental states like beliefs can extend into the environment. I raise two problems for the argument. The first problem is that it is more difficult than Clark and Chalmers think to set up the Tetris example so that application of the parity principle might render it a case of extended mind. The second problem is that, even (...) when appropriate versions of the argumentative examples can be constructed, the availability of a second, internalist parity principle precludes the possibility of inferring that the mind extends. Choosing which parity principle we ought to wield would involve deciding beforehand whether or not the mind can extend. Thus Clark and Chalmers beg the question by employing their parity principle rather than the internalist one. I conclude that they fail to provide a proper argument to support the extended mind thesis. (shrink)
