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.

There’s a possibly more interesting general question: does technology transform and extend the mind and our mental powers? In a widely discussed 1998 paper titled “The Extended Mind”, Andy Clark and David Chalmers argue that mind and cognition can extend outside the head and can include items and processes in the world. In their thought experiment, Otto has alzheimer’s syndrome but does not lose his ability to function because he records information he learns in a notebook that he always carries. Thus, C&C claim, Otto continues to have beliefs. The notebooks function as his memory. C&C propose a "parity principle": a part of the world is part of a cognitive process if it "functions as a process which, were it done in the head, we would have no hesitation in recognizing [it] as part of the cognitive process .... Cognitive processes ain't (all) in the head!" (in Menary p. 29, original emphasis).

This paper attempts to do two things. First, it recounts the problem of intentionality, as it has typically been conceptualized, and argues that it needs to be reconceptualized in light of the radical form of externalism most commonly referred to as the extended mind thesis. Second, it provides an explicit, novel argument for that thesis, what I call the argument from meaning making, and offers some defense of that argument. This second task occupies the core of the paper, and in completing it I distinguish _active _ _cognition_ from _cyborg fantasy arguments_ for externalism, and develop the analogy between the extended mind thesis in the cognitive sciences and developmental systems theory in developmental biology. The rethinking of the problem of intentionality on offer leads not so much to a solution as to a dissolution of that problem, as traditionally conceived.

Andy Clark and David Chalmers have recently argued that the world beyond our skin can constitute part of the mind. That is, our minds can and sometimes do extend beyond our heads and bodies. Clark and Chalmers refer to this claim as the 'Extended Mind'. After illustrating the Extended Mind via a thought-experiment I turn to consider a criticism made by Lawrence Shapiro. After outlining Shapiro's claim I will show that in fact this does little to call into to doubt the Extended Mind. However, Clark holds that the Extended Mind does face a serious criticism from the threat of 'Mental Bloat'; the worry here is that arguing that the mind extends beyond the skin quickly leads to absurdities. I consider Clark's response to this worry but find it to be unconvincing. However, I go on to show that there is in fact little to fear from Mental Bloat. Therefore, it will be my conclusion that there is some reason to hold that the mind ain't just in the head.

Recent developments under the keywords dynamicism, embodiment and situated cognition suggest the view that cognitive systems are not confined to the neural sys‐tem but leak into the world beyond the traditional system boundaries. This is the thesis of extended cognition. Such an extension of the cognitive vehicles leads to a new kind of content externalism, known as active externalism. The essay pursues three objectives: firstly, to distinguish the theses of extended cognitive and active externalism. Secondly, to delineate active externalism from its various passive-externalist precursors in the form of physical, historical and social externalism and to scrutinize its special position, which amounts to a comprehensive discussion and analysis of all variants of mental externalism. And thirdly, to show that social externalism as opposed to physical and historical externalism allows for a gradual transition from passive to active mental externalism.

Is consciousness all in the head, or might the minimal physical substrate for some forms of conscious experience include the goings on in the (rest of the) body and the world? Such a view might be dubbed (by analogy with Clark and Chalmers’s ( 1998 ) claims concerning ‘the extended mind’) ‘the extended conscious mind’. In this article, I review a variety of arguments for the extended conscious mind, and find them flawed. Arguments for extended cognition, I conclude, do not generalize to arguments for an extended conscious mind.

Clark and Chalmers (2002) advance two hypotheses that both cognition and the mind extend into the environment. Both hypotheses are grounded in active externalism about mental content and the Parity Principle. Active externalism proposes that the external features of the environment in the present directly influence our mental contents and behavior. The Parity Principle states that a process or state in the environment is cognitive if it is functionally equivalent to a comparable intracranial cognitive process. This paper reviews two of the strongest replies to the hypotheses, namely that arguments for them commit the coupling-constitution fallacy and that the hypothesis of extended cognition is incompatible with any satisfactory criteria that distinguishes between cognitive and non-cognitive processes. This paper argues that a dynamical systems approach avoids both objections and offers a conceptual and methodological framework for an extended cognitive science. Lastly, an account of collective intentionality will be considered to show how groups of individuals can be the bearers of mental states.

The idea of dreams being mere internal artifacts of the mind does not seem to be essential to externalism and extended mind theories, which seem as if they would function as well without this additional assumption. The Many Bubble Interpretation could allow a simpler rationale to externalist theories, which may be even simpler if the assumption that dreams have no worthwhile content outside the mind is omitted.

Some cognitive states — e.g. states of thinking, calculating, navigating — may be partially external because, at least sometimes, these states depend on the use of symbols and artifacts that are outside the body. Maps, signs, writing implements may sometimes be as inextricably bound up with the workings of cognition as neural structures or internally realized symbols (if there are any). According to what Clark and Chalmers [1998] call active externalism, the environment can drive and so partially constitute cognitive processes. Where does the mind stop and the rest of the world begin? If active externalism is right, then the boundary cannot be drawn at the skull. The mind reaches – or at least can reach --- beyond the limits of the body out into the world.

Leading scholars respond to the famous proposition by Andy Clark and David Chalmers that cognition and mind are not located exclusively in the head.
