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.

It is argued that standard arguments for the Externalism of mental states do not succeed in the case of pre-linguistic mental states. Further, it is noted that standard arguments for Internalism appeal to the principle that our individuation of mental states should be driven by what states are explanatory in our best cognitive science. This principle is used against the Internalist to reject the necessity of narrow individuation of mental states, even in the prelinguistic case. This is done by showing how the explanation of some phenomena requires quantification over broadly-individuated, world-involving states; sometimes externalism is required. Although these illustrative phenomena are not mental, they are enough to show the general argumentative strategy to be incorrect: scientific explanation does not require narrowly-individuated states.

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.

According to the view known variously as the extended mind (Clark & Chalmers 1998), vehicle externalism (Hurley 1998; Rowlands 2003, 2006) active externalism (Clark and Chalmers 1998), locational externalism (Wilson 2004) and environmentalism (Rowlands 1999), at least some token mental processes extend into the cognizing organism’s environment in that they are composed, partly (and, on most versions, contingently), of manipulative, exploitative, and transformative operations performed by that subject on suitable environmental structures. More precisely, what I shall refer to as the thesis of the extended mind (EM) is constituted by the following claims: • The world is an external store of information relevant to processes such as perceiving, remembering, reasoning … (and possibly) experiencing. • At least some mental processes are hybrid – they straddle both internal and external operations. • The external operations take the form of action: manipulation, exploitation and transformation of environmental structures – ones that carry information relevant to the accomplishing of a given task. • At least some of the internal processes are ones concerned with supplying a subject with the ability to appropriately use relevant structures in its environment. As I shall understand it, therefore, the thesis of the extended mind is (1) an ontic thesis, of (2) partial and (3) contingent (4) composition of (5) some mental processes.[1] 1. It is ontic in the sense that it is a thesis about what (some) mental processes are, as opposed to an epistemic thesis about the best way of understanding mental processes. This ontic claim, of course, has an epistemic consequence: it is not possible to understand the nature of at least some of the mental processes without understanding the extent to which that organism is capable of manipulating, exploiting and transforming relevant structures in its environment (Rowlands 1999)..

This paper investigates a new species of skeptical reasoning about visual experience that takes its start from developments in perceptual science (especially recent work on change blindness and inattentional blindness). According to this skepticism, the impression of visual awareness of the environment in full detail and high resolution is illusory. I argue that the new skepticism depends on misguided assumptions about the character of perceptual experience, about whether perceptual experiences are 'internal' states, and about how best to understand the relationship between a person's or animal's perceptual capacities and the brain-level or neural processes on which they depend. I propose a conception of perceptual experience as a form of skillful engagement with the environment on the part of the whole person or animal.

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).

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.

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.
