Philosophical interest in situated cognition has been focused most intensely on the claim that human cognitive processes extend from the brain into the tools humans use. As we see it, this radical hypothesis is sustained by two kinds of mistakes, confusing coupling relations with constitutive relations and an inattention to the mark of the cognitive. Here we wish to draw attention to these mistakes and show just how pervasive they are. That is, for all that the radical philosophers have said, (...) the mind is still in the head. (shrink)

This is a plausible reading of what Clark and Chalmers had in mind at the time, but it is not the radical claim at stake in the extended cognition debate.[1] It is a familiar functionalist view of cognition and the mind that it can be realized in a wide range of distinct material bases. Thus, for many species of functionalism about cognition and the mind, it follows that they can be realized in extracranial substrates.[2] And, in truth, even some non-functionalist (...) views of cognition apparently allow for the possibility that cognition extends into the external world.[3] So, the (logical, conceptual, or nomological) possibility of extended cognition seems to us not the kind of radical view the advocates of this view have often implied. This is not, of course, to assess or pass judgment on the truth of these possibilities; it is only to note that they are not what most agitates people about the hypothesis of extended cognition. Framing the radical extended cognition hypothesis is a more delicate matter than framing the modal extended cognition hypothesis, but something like the following is in the ballpark. The radical extended cognition hypothesis maintains that, in many mundane cases of tool use, human cognitive processes extend into the tools. The principal reason this hypothesis is so delicate is that there remains much room for dispute about what constitutes a. (shrink)

That about sums up what is wrong with Clark.

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.

Clark never in so many words defends the idea that there are actual cases of extended cognition. Rather, his tacit commitment must be inferred from such things as his proposal that the brain is made to use tools, so we should view tools as part of the mind (Cf., Clark, 2005, p. 8ff.). (shrink)

That about sums up what is wrong with Clark’s extended mind hypothesis. Clark apparently thinks that the nature of the processes internal to a pencil, Rolodex, computer, cell phone, piece of string, or whatever, has nothing to do with whether that thing carries out cognitive processing.[1] Rather, what matters is how the thing interacts with a cognitive agent; the thing has to be coupled to a cognitive agent in a particular kind of way. Clark (20??) gives three conditions that constitute (...) a rough or partial specification of the kind of coupling required. (shrink)

The extended-mind thesis (EM) is the claim that mentality need not be situated just in the brain, or even within the boundaries of the skin. Some versions take "extended selves" be to relatively transitory couplings of biological organisms and external resources. First, I show how EM can be seen as an extension of traditional views of mind. Then, after voicing a couple of qualms about EM, I reject EM in favor of a more modest hypothesis that recognizes enduring subjects of (...) experience and agents with integrated bodies. Nonetheless, my modest hypothesis allows subpersonal states to have nonbiological parts that play essential roles in cognitive processing. I present empirical warrant for this modest hypothesis and show how it leaves room for science and religion to coexist. (shrink)

A new position in the philosophy of mind has recently appeared: the extended mind hypothesis (EMH). Some of its proponents think the EMH, which says that a subject's mental states can extend into the local environment, shows that internalism is false. I argue that this is wrong. The EMH does not refute internalism; in fact, it necessarily does not do so. The popular assumption that the EMH spells trouble for internalists is premised on a bad characterization of the internalist thesis—albeit (...) one that most internalists have adhered to. I show that internalism is entirely compatible with the EMH. This view should prompt us to reconsider the characterization of internalism, and in conclusion I make some brief remarks about how that project might proceed. (shrink)

In their historical overview of cognitive science, Bechtel, Abraham- son and Graham (1999) describe the field as expanding in focus be- ginning in the mid-1980s. The field had spent the previous 25 years on internalist, high-level GOFAI (“good old fashioned artificial intelli- gence” [Haugeland 1985]), and was finally moving “outwards into the environment and downards into the brain” (Bechtel et al, 1999, p.75). One important force behind the downward movement was Patricia Churchland’s Neurophilosophy (1986). This book began a movement bearing (...) its name, one that truly came of age in 1999 when Kath- leen Akins won a million-dollar fellowship to begin the McDonnell Project in Philosophy and the Neurosciences. The McDonnell Project put neurophilosophy at the forefront of philosophy of mind and cogni- tive science, yielding proliferating articles, conferences, special journal issues and books. In two major new books, neurophilosophers Patricia Churchland (2002) and John Bickle (2003) clearly feel this newfound prominence: Churchland mocks those who do not apply findings in neuroscience to philosophical problems as “no-brainers”; Bickle mocks anyone with traditional philosophical concerns, including “naturalistic philosophers of mind” and other neurophilosophers.

In this talk, we defend extended cognition against several criticisms. We argue that extended cognition does not derive from armchair theorizing and that it neither ignores the results of the neural sciences, nor minimizes the importance of the brain in the production of intelligent behavior. We also argue that explanatory success in the cognitive sciences does not depend on localist or reductionist methodologies; part of our argument for this is a defense of what might be called ‘holistic science’.

In the movie, Memento, the hero, Leonard, suffers from a form of anterograde amnesia that results in an inability to lay down new memories. Nonetheless, he sets out on a quest to find his wife.

A suitable project for the new Millenium is to radically reconfigure our image of human rationality. Such a project is already underway, within the Cognitive Sciences, under the umbrellas of work in Situated Cognition, Distributed and De-centralized Cogition, Real-world Robotics and Artificial Life1. Such approaches, however, are often criticized for giving certain aspects of rationality too wide a berth. They focus their attention on on such superficially poor cousins as.

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.

The key question in this three way debate is the role of the collectivity and of agency. Collins and Shrager debate whether cognitive psychology has, like the sociology of knowledge, always taken the mind to extend beyond the individual. They agree that irrespective of the history, socialization is key to understanding the mind and that this is compatible with Clark’s position; the novelty in Clark’s “extended mind” position appears to be the role of the material rather than the role of (...) other minds. Collins and Clark debate the relationship between self, agency, and the human collectivity. Collins argues that the Clark’s extended mind fails to stress the asymmetry of the relationship between the self and its material “scaffolding.” Clark accepts that there is asymmetry but that an asymmetrical ensemble is sufficient to explain the self. Collins says that we know too little about the material world to pursue such a model to the exclusion of other approaches including that both the collectivity and language have agency. The collectivity must be kept in mind! (Though what follows is a robust exchange of views it is also a cooperative effort, authors communicating “backstage” with each other to try to make the disagreements as clear and to the point as possible.).

Grush's framework has epistemological implications and explains how it is possible to acquire offline empirical knowledge. It also complements the extended-mind thesis, which says that mind leaks into the world. Grush's framework suggests that the world leaks into the mind through the offline deployment of emulators that we usually deploy in our experience of the world.

Experimental studies indicate that nonhuman animals and infants represent numerosities above three or four approximately and that their mental number line is logarithmic rather than linear. In contrast, human children from most cultures gradually acquire the capacity to denote exact cardinal values. To explain this difference, I take an extended mind perspective, arguing that the distinctly human ability to use external representations as a complement for internal cognitive operations enables us to represent natural numbers. Reviewing neuroscientific, developmental, and anthropological evidence, (...) I argue that the use of external media that represent natural numbers (like number words, body parts, tokens or numerals) influences the functional architecture of the brain, which suggests a two-way traffic between the brain and cultural public representations.

This paper reformulates some of the questions raised by extended mind theorists from an enactive, life/mind continuity perspective. Because of its reliance on concepts such as autopoiesis, the enactive approach has been deemed internalist and thus incompatible with the extended mind hypothesis. This paper answers this criticism by showing (1) that the relation between organism and cogniser is not one of co-extension, (2) that cognition is a relational phenomenon and thereby has no location, and (3) that the individuality of a (...) cogniser is inevitably linked with the question of its autonomy, a question ignored by the extended mind hypothesis but for which the enactive approach proposes a precise, operational, albeit non-functionalist answer. The paper raises a pespective of embedded and intersecting forms of autonomous identity generation, some of which correspond to the canonical cases discussed in the extended mind literature, but on the whole of wider generality. In addressing these issues, this paper proposes unbiased, non-species specific definitions of cognition, agency and mediation, thus filling in gaps in the extended mind debates that have led to paradoxical situations and a problematic over-reliance on intutions about what counts as cognitive.

Locked-in syndrome (LIS) is a severe neurological condition that typically leaves a patient unable to move, talk and, in many cases, initiate communication. Brain Computer Interfaces (or BCIs) promise to enable individuals with conditions like LIS to re-engage with their physical and social worlds. In this paper we will use extended mind theory to offer a way of seeing the potential of BCIs when attached to, or implanted in, individuals with LIS. In particular, we will contend that functionally integrated BCIs (...) extend the minds of individuals with LIS beyond their bodies, allowing them greater autonomy than they can typically hope for in living with their condition. This raises important philosophical questions about the implications of BCI technology, particularly the potential to change selves, and ethical questions about whether society has a responsibility to aid these individuals in re-engaging with their physical and social worlds. It also raises some important questions about when these interventions should be offered to individuals with LIS and respecting the rights of these individuals to refuse intervention. By aiding willing individuals in re-engaging with their physical and social worlds, BCIs open up avenues of opportunity taken for granted by able individuals and introduce new ways in which these individuals can be harmed. These latter considerations serve to highlight our emergent social responsibilities to those individuals who will be suitable for, and receive, BCIs. (shrink)

We review the argument made by Clark and Chalmers in _Analysis_ for a limited externalism and extend their argument from declarative knowledge to procedural knowledge.

We propose to extend Clark and Chalmer’s concept of the extended mind to consider the possibility that social institutions (e.g., legal systems, museums) may operate in ways similar to the hand-held conveniences (notebooks, calculators) that are often used as examples of extended mind. The inspiration for this suggestion can be found in the writings of Hegel on “objective spirit” which involves the mind in a constant process of externalizing and internalizing. For Hegel, social institutions are pieces of the mind, externalized (...) in their specific time and place. These institutions are the products of shared mental processes. We then use these institutions instrumentally to do further cognitive work, for example, to solve problems or to control behavior. (shrink)

Clark and Chalmers argue that the mind is extended – that is, its boundary lies beyond the skin. In this essay, I will criticize this conclusion. However, I will also defend some of the more controversial elements of Clark and Chalmers's argument. I reject their conclusion because I think that their argument shows that a seemingly innocuous assumption, about internal states and processes, is flawed. My goal is not to conclusively refute Clark and Chalmers's conclusion. My aim is only to (...) reveal the best alternative for those who remain skeptical about the existence – or, perhaps, even the possibility – of extended minds. (shrink)

According to many forms of Externalism now popular in the Philosophy of Mind, the contents of our thoughts depend in part upon our physical or social milieu.1 These forms of Externalism leave unchallenged the thesis that the ~non-factive! attitudes we bear towards these contents are independent of physical or social milieu. This paper challenges that thesis. It is argued here that publicly forwarding a content as a supposition for the sake of argument is, under conditions not themselves guaranteeing the existence (...) of that state, sufficient for occupancy of the intentional state of supposing that content. Because a saying may literally create an intentional state, whether one is in such a state does not depend solely upon how things are within one’s skin. Rather, even leaving content fixed, the attitude borne toward that content depends in part upon what norms are in force in one’s milieu. (shrink)

Less than a decade ago, “rational choice theory” seemed oddly impervious to criticism. Hundreds of books, articles and studies were published every year, attacking the theory from every angle, yet it continued to attract new converts. How times have changed! The “anomalies” that Richard Thaler once blithely cataloged for the Journal of Economic Perspectives are now widely regarded, not as curious deviations from the norm, but as falsifying counterexamples to the entire project of neoclassical economics. The work of experimental game (...) theorists has perhaps been the most influential in showing that people do not maximize expected utility, in any plausible sense of the terms “maximize,” “expected,” or “utility.” The evidence is so overwhelming and incontrovertible that, by the time one gets to the end of a book like Dan Ariely’s Predictably Irrational,1 it begins to feel like piling on. The suggestion is pretty clear: not only are people not as rational as decision and game theorists have traditionally taken them to be, they are not even as rational as they themselves take themselves to be. This conclusion, however, is not self-evident. The standard interpretation of these findings is that people are irrational: their estimation of probabilities is vulnerable to framing effects, their treatment of (equivalent) losses and gains is asymmetric, their choices violate the sure-thing principle, they discount the future hyperbolically, and so on. Indeed, after surveying the experimental findings, one begins to wonder how people manage to get on in their daily lives at all, given the seriousness and ubiquity of these deliberative pathologies. And yet, most people do manage to get on, in some form or another. This in itself suggests an.. (shrink)

Certain empirical results suggest a way of challenging two natural and widespread assumptions about the mind. One assumption is about the relations between perception and action. This shows up in the widespread conception of perception and action in terms of input and output, respectively. Perception is conceived as input from world to mind and action is conceived as output from mind to world. The other assumption is about the relations between mind and world. It influences various opposed views about whether (...) the contents of the mind are in principle independent of the outside world. (shrink)

We all know about the vehicle/content distinction (see Dennett 1991a, Millikan 1991, 1993). We shouldn't confuse properties represented in content with properties of vehicles of content. In particular, we shouldn't confuse the personal and subpersonal levels. The contents of the mental states of subject/agents are at the personal level. Vehicles of content are causally explanatory subpersonal events or processes or states. We shouldn't suppose that the properties of vehicles must be projected into what they represent for subject/agents, or vice versa. (...) This would be to confuse the personal and subpersonal levels.

We present data and argument to show that in Tetris - a real-time interactive video game - certain cognitive and perceptual problems are more quickly, easily, and reliably solved by performing actions in the world rather than by performing computational actions in the head alone. We have found that some translations and rotations are best understood as using the world to improve cognition. These actions are not used to implement a plan, or to implement a reaction; they are used to (...) change the world in order to simplify the problem-solving task. Thus, we distinguish pragmatic actions ñ actions performed to bring one physically closer to a goal - from epistemic actions - actions performed to uncover information that is hidden or hard to compute mentally. To illustrate the need for epistemic actions, we first develop a standard information-processing model of Tetris-cognition, and show that it cannot explain performance data from human players of the game - even when we relax the assumption of fully sequential processing. Standard models disregard many actions taken by players because they appear unmotivated or superfluous. However, we describe many such actions that are actually taken by players that are far from superfluous, and that play valuable roles in improving human performance. We argue that traditional accounts are limited because they regard action as having a single function: to change the world. By recognizing a second function of action - an epistemic function - we can explain many of the actions that a traditional model cannot. Although, our argument is supported by numerous examples specifically from Tetris, we outline how the one category of epistemic action can be incorporated into theories of action more generally.

I draw upon the conceptual resources of the extended mind thesis (EM) to analyze empathy and interpersonal understanding. Against the dominant mentalistic paradigm, I argue that empathy is fundamentally an extended bodily activity and that much of our social understanding happens outside of the head. First, I look at how the two dominant models of interpersonal understanding, theory theory and simulation theory, portray the cognitive link between folk psychology and empathy. Next, I challenge their internalist orthodoxy and offer an alternative (...) "extended" characterization of empathy. In support of this characterization, I analyze some narratives of individuals with Moebius syndrome, a kind of expressive deficit resulting from bilateral facial paralysis. I conclude by discussing how a Zen Buddhist ethics of responsiveness is helpful for articulating the practical significance of an extended, body-based account of empathy. (shrink)

The extended mind thesis is the claim that mental states extend beyond the skulls of the agents whose states they are. This seemingly obscure and bizarre claim has far-reaching implications for neuroethics, I argue. In the first half of this article, I sketch the extended mind thesis and defend it against criticisms. In the second half, I turn to its neuroethical implications. I argue that the extended mind thesis entails the falsity of the claim that interventions into the brain are (...) especially problematic just because they are internal interventions, but that many objections to such interventions rely, at least in part, on this claim. Further, I argue that the thesis alters the focus of neuroethics, away from the question of whether we ought to allow interventions into the mind, and toward the question of which interventions we ought to allow and under what conditions. The extended mind thesis dramatically expands the scope of neuroethics: because interventions into the environment of agents can count as interventions into their minds, decisions concerning such interventions become questions for neuroethics.

This brief article introduces a symposium discussing the extended mind thesis and its suggestive relation to religious thought. Essays by Mark Rowlands, Lynne Rudder Baker, Teed Rockwell, Joel Krueger, Leonard Angel, and Matthew Day present a variety of perspectives.

The notion of the cyborg has exercised the popular imagination for almost two hundred years. In very general terms the idea that a living entity can be a hybrid of both organic matter and mechanical parts, and for all intents and purposes be seamlessly functional and self-regulating, was prefigured in literary works such as Shelly
s Frankenstein (1816/18) and Samuel Butler
s Erewhon (1872). This notion of hybridism has been a staple theme of 20th century science fiction writing, television programmes and the (...) cinema. For the most part, these works trade on a deep sense of unease we have about our personal identity – how could some non-organic matter to which I have so little conscious access count as a bona fide part of me? Cognitive scientist and philosopher, Andy Clark, picks up this general theme and presents an empirical and philosophical case for the following inextricably linked theses. (shrink)

To know is to cognize, to cognize is to be a culturally bounded, rationality-bounded and environmentally located agent. Knowledge and cognition are thus dual aspects of human sociality. If social epistemology has the formation, acquisition, mediation, transmission and dissemination of knowledge in complex communities of knowers as its subject matter, then its third party character is essentially stigmergic. In its most generic formulation, stigmergy is the phenomenon of indirect communication mediated by modifications of the environment. Extending this notion one might (...) conceive of social stigmergy as the extra-cranial analog of an artifcial neural network providing epistemic structure. This paper recommends a stigmergic framework for social epistemology to account for the supposed tension between individual action, wants and beliefs and the social corpora. We also propose that the so-called "extended mind" thesis offers the requisite stigmergic cognitive analog to stigmergic knowledge. Stigmergy as a theory of interaction within complex systems theory is illustrated through an example that runs on a particle swarm optimization algorithm. (shrink)

Where does the mind stop and the rest of the world begin? In their famous 1998 paper "The Extended Mind," philosophers Andy Clark and David Chalmers posed this question and answered it provocatively: cognitive processes "ain't all in the head." The environment has an active role in driving cognition; cognition is sometimes made up of neural, bodily, and environmental processes. Their argument excited a vigorous debate among philosophers, both supporters and detractors. This volume brings together for the first time the (...) best responses to Clark and Chalmers's bold proposal. These responses, together with the original paper by Clark and Chalmers, offer a valuable overview of the latest research on the extended mind thesis. The contributors first discuss (and answer) objections raised to Clark and Chalmers's thesis. Andy Clark himself responds to critics in an essay that uses the movie Memento's amnesia-aiding notes and tattoos to illustrate the workings of the extended mind. Contributors then consider the different directions in which the extended mind project might be taken, including the need for an approach that focuses on cognitive activity and practice. (shrink)

Naturalistic philosophers ought to think that the mind is continuous with the rest of the world and should not, therefore, be surprised by the findings of the extended mind, cognitive integration and enactivism. Not everyone is convinced that all mental phenomena are continuous with the rest of the world. For example, intentionality is often formulated in a way that makes the mind discontinuous with the rest of the world. This is a consequence of Brentano’s formulation of intentionality, I suggest, and (...) can be overcome by revealing that the concept of intentional directedness as he receives it from the Scholastics is quite consistent with the continuity thesis. It is only when intentional directedness is conjoined with intentional inexistence that intentionality and content are consistent with a discontinuity thesis (such as Brentano’s thesis). This makes room to develop an account of intentional directedness that is consistent with the continuity thesis in the form of Peirce’s representational principle. I also argue against a form of the discontinuity thesis in the guise of the derived/underived content distinction. Having shown that intentionality is consistent with the continuity thesis I argue that we should focus on intentionality and representation as bodily enacted. I conclude that we would be better off focussing on representation and intentionality in action rather than giving abstract functional accounts of extended cognition. (shrink)

In this paper I aim to show that the creation and manipulation of written vehicles is part of our cognitive processing and, therefore, that writing transforms our cognitive abilities. I do this from the perspective of cognitive integration: completing a complex cognitive, or mental, task is enabled by a co-ordinated interaction between neural processes, bodily processes and manipulating written sentences. In section one I introduce Harris’ criticisms of ways in which writing has been said to restructure thought (Goody 1968; McLuhan (...) 1962, 1964; Ong 1982). This will give us a preliminary idea about possible pitfalls for a cognitive integrationist account. The second section outlines, firstly, how integrated cognitive systems function. Secondly, the model is applied to a hybrid mental act where writing allows us to complete complex cognitive tasks. The final section outlines the sense in which, following Harris, there is “a more realistic picture of how writing restructures thought” [Harris, R., 1989. How does writing restructure thought? Language and Communication 9 (2/3) 99–106] that is concealed by the ‘romantic fantasies’ of theorists such as the above. This picture is one of writing providing an autoglottic space in which a new form of theoretical thinking becomes prevalent. The cognitive integrationist understands this in terms of the nature of the written vehicles and how we manipulate them. (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.
