Discussions about the extended mind have ‘extended’ in various directions in the last decades. While applied to other aspects of human cognition and even consciousness, the extended-mind hypothesis has also been criticized, as it questions fundamental ideas such as the image of a dual world, divided between an external and an internal domain by the border of ‘skin and skull’, the idea of a localized and constant decision center, and the role of internal representations. (...) We suggest that the main virtue of the hypothesis is not as a theory per se, but as a vaccine against persistent metaphysical prejudices about the mind’s structure, functions and borders. Being an hypothesis about the most efficient ways to combine resources and problems, and not a theory about the mind’s a-priori constitution, the extended mind view moves the focus from ontology to pragmatics and helps purify philosophy of mind from metaphysical remainders.

The Extended Mind Hypothesis (EMH) needs a defence of phenomenal externalism in order to be consistent with an indispensable condition for attributing extended beliefs, concerning the conscious past endorsement of information. However, it is difficult, if not impossible, to envisage such a defence. Proponents ofthe EMH are thus confronted with a difficult dilemma: they either accept absurd attributions of belief, and thus deflate EMH, or incorporate, for compatibility reasons, the conscious past endorsement condition for extended (...) belief attribution, implying a seemingly unavailable defence of phenomenal externalism, and thus risk inconsistency within EMH. Either way, EMH is threatened. (shrink)

This article analyzes the extended mind hypothesis that has been discussed during the past two decades following the article “The Extended Mind” by Andy Clark and David Chalmers. It examines the position of active externalism and notes the shortcomings of the arguments supporting this position as proposed by Clark and Chalmers. It is demonstrated that the cultural-historical psychology developed by Vygotsky represents an alternative means of substantiating the extended mind hypothesis. Interpreting Vygotsky’s (...) position as “active social externalism,” the author contrasts Vygotsky’s theory with the active externalism of Clark and Chalmers, as well as with the classical externalism advocated by Putnam and Burge, showing the advantage of Vygotsky’s approach. This advantage has been seen in the ability of Vygotsky’s active social externalism to avoid the problems faced by other externalist approaches to explaining the mind. (shrink)

After a brief summary of Andy Clark's book, Supersizing the Mind I address Clark's approach to language which I argue to be inadequate. Clark is criticized for reifying language, thus neglecting that it is an interpersonal activity, not a stable system of symbols. With a starting point in language as a social phenomenon, I suggest an ecological approach to the extended mind hypothesis, arguing against Clark's assumption that the extended mind is necessarily brain-centered.

In this paper we develop a novel argument against the extended mind hypothesis. Our argument constitutes an advance in the debate, insofar as we employ only premises that are acceptable to a coarse-grained functionalist, and we do not rely on functional disanalogies between putative examples of extended minds and ordinary human beings that are just a matter of fine detail or degree. Thus, we beg no questions against proponents of the extended mind hypothesis. (...) Rather, our argument consists in making use of the following necessary condition on holding a belief for a reason: To believe something for a reason, one must come to believe it in virtue of attitudes that epistemically rationalize the belief that is formed, and one must come to believe in virtue of the fact that these attitudes epistemically rationalize the new belief. We show that many external objects that defenders of the extended mind hypothesis have claimed are beliefs cannot constitute a belief had for a reason, as they necessarily fail to satisfy the necessary condition. Our first thesis, then, is that beliefs had for reasons cannot be extended in the most interesting way specified by the extended mind hypothesis. Furthermore, if we add to our argument the premise that every token belief is something that could have been had for a reason, we can derive the stronger thesis that no beliefs can be extended in this way.

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)

The Extended Mind Hypothesis (EM) strikes many as counter-intuitive. It is the claim that things outside of human bodies are literally parts of human minds. But EM rests upon a plausible idea: that the world itself is minded when parts of it are functionally equivalent to parts of human minds. In this paper, we address two intuitive criticisms of EM recently expressed by Sam Coleman (Coleman, 2011). The first is that the examples of extended mind (...) offered by advocates of EM are not parts of minds, because subjects are not “conscious” or “immediately aware” of those parts of the external world. The second is that the principle at the heart of the argument for EM is biased in favor of EM. We show how both of these intuitive criticisms of EM fail. Our ultimate aim is to suggest that the counter-intuitiveness of EM is not a barrier to its acceptance. (shrink)

This paper introduces pictures more generally into the discussion of cognition and mind. I will argue that pictures play a decisive role in shaping our mental lives because they have changed (and constantly keep changing) the ways we access the world. Focusing on pictures will therefore also shed new light on various claims within the field of embodied cognition. In the first half of this paper I address the question of whether, and in what possible ways, pictures might be (...) considered to be part of our extended mind. We will see however, that the explanatory means contingent upon the extended mind thesis – i.e. the claim that the vehicles of cognition are not confined to the boundaries of the individual organism – can only take us so far. Beyond such claims it will be pivotal to understand in what specific ways pictures might be regarded as being at the basis of certain perceptions of and interactions with the world. I will therefore address, in the second half of this paper, in what ways enactive and affective elements should inform our theory of the pictorial mind. In the course of this discussion it will become apparent that pictures are strange objects because they differ profoundly from other objects surrounding us. And it will also turn out that pictures – beyond the fact that they can be considered to be tools for our mind (in the sense that they facilitate our access to the world) – are rather strange or stubborn tools in that something in them resists full integration into our cognitive routines.

Does cognition sometimes literally extend into the extra-organismic environment (Clark, 2003), or is it always “merely” environmentally embedded (Rupert, 2004)? Underlying this current border dispute is the question about how to individuate cognitive processes on principled grounds. Based on recent evidence about the active role of representation selection and construction in learning how to reason (Stenning, 2002), I raise the question: what makes two distinct, modality-specific pen-and-paper manipulations of external representations – diagrams versus sentences – cognitive processes of the same (...) kind, e.g. episodes of syllogistic reasoning? In response, I defend a “division of labor” hypothesis, according to which external representations are dependent on perceptually grounded neural representations and mechanisms to guide our behavior; these internal mechanisms, however, are dependent on external representations to have their syllogistic content fixed. Only their joint contributions qualify the extended computational process as an episode of syllogistic reasoning in good standing. (shrink)

Hilary Putnam has famously argued that “we are brains in a vat” is necessarily false. The argument assumes content externalism (also known as semantic externalism and anti-individualism), that is, the view that the individuation conditions of mental content depend, in part, on external or relational properties of the subject’s environment. Recently content externalism has given rise to the hypothesis of the extended mind, whereby mental states are not only externally individuated but also externally located states. This chapter (...) argues that when content externalism is combined with the extended mind hypothesis it is robbed of its anti-skeptical power. Given the extended mind hypothesis, the supercomputer and the envatted brain can be regarded as aspects of the extended mind of the evil scientist. On this view, the thought contents of the coupled brain–computer–scientist system do not differ from those of a normal human. But without a difference in thought contents Putnam’s anti-skeptical argument crumbles. (shrink)

Two very different forms of externalism about mental states appear prima facie unrelated: Williamson’s (1995, 2000) claim that knowledge is a mental state, and Clark & Chalmers’ (1998) extended mind hypothesis. I demonstrate, however, that the two approaches justify their radically externalist by appealing to the same argument from explanatory generality. I argue that if one accepts either Williamson’s claims or Clark & Chalmers’ claims on considerations of explanatory generality then, ceteris paribus, one should accept the other. (...) This conclusion has implications for philosophy of mind, epistemology, and cognitive science. (shrink)

It has been twenty years since Clark and Chalmers published “The Extended Mind.” In the present article I review the development of the extended mind hypothesis across what some proponents have defined as three theoretical “waves.” From first‐wave extended mind theory, based on the parity principle, to second‐wave complementarity, to the third wave, characterized as an uneasy integration of predictive processing and enactivist dynamics, extended mind theorists have faced and solved a (...) number of problems along the way. The fact that the hypothesis continues to spark debate and to generate both new insights and new objections suggests that it continues to play a productive role in contemporary philosophy of mind.

. The extended‐mind thesis 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)

Given how epistemologists conceive of understanding, to what degree do we understand the hypothesis of extended mind? If the extended mind debate is a substantive dispute, then we have only superficial understanding of the extended mind hypothesis. And if we have deep understanding of the extended mind hypothesis, then the debate over this hypothesis is nothing but a verbal dispute.

On the extended mind hypothesis (EM), many of our cognitive states and processes are hybrids, unevenly distributed across biological and nonbiological realms. In certain circumstances, things - artifacts, media, or technologies - can have a cognitive life, with histories often as idiosyncratic as those of the embodied brains with which they couple. The realm of the mental can spread across the physical, social, and cultural environments as well as bodies and brains. My independent aims in this chapter (...) are: first, to describe two compatible but distinct movements or "waves" within the EM literature, arguing for the priority of the second wave (and gesturing briefly toward a third); and, second, to defend and illustrate the interdisciplinary implications of EM as best understood, specifically for historical disciplines, by sketching two case studies.

The hypothesis that cognition, and the mind more generally, might extend beyond the margins of the body came to prominence in the 1990s. The most oft-cited source is Andy Clark and David Chalmers’ celebrated 1998 article ‘The Extended Mind’. The six papers in this issue of Essays in Philosophy explore various aspects of the extended mind thesis and related ideas. While all but one of them discuss Clark and Chalmers’ article, and all are sympathetic (...) to the extended mind movement, the later papers in the issue are increasingly of the opinion that it is time for the movement to abandon that early framework.

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 (...) class='Hi'>hypothesis of extended mind (HEM) is incoherent. However, this view also indicates why the hypothesis of extended cognition (HEC) could be true.

In this paper, I will critically consider Clark and Chalmers’ hypothesis of the «extended mind» in order to sketch a possible phenomenological account of active externalism, by following three steps: I will consider Clark and Chalmers’ hypothesis within the broader context of the so-called «physical symbol system hypothesis» theorized by Herbert A. Simon; I will connect the problem of the «extended mind» to that of the «extended self», with particular regard to the (...) context of digitalization; I will take into account an explanatory dimension that has been fundamentally underrated by externalist theories: the dimension of the human body and its relationship to mind, which I understand from a phenomenological perspective. My ultimate goal is to show how phenomenology could provide the missing theoretical framework to develop a more complex and comprehensive theory of the extended self. (shrink)

The extended mind hypothesis (Clark and Chalmers in Analysis 58(1):7–19, 1998; Clark 2008) is an influential hypothesis in philosophy of mind and cognitive science. I argue that the extended mind hypothesis is born to be wild. It has undeniable and irrepressible tendencies of flouting grounding assumptions of the traditional information-processing paradigm. I present case-studies from social cognition which not only support the extended mind proposal but also bring out its inherent (...) wildness. In particular, I focus on cases of action-understanding and discuss the role of embodied intentionality in the extended mind project. I discuss two theories of action-understanding for exploring the support for the extended mind hypothesis in embodied intersubjective interaction, namely, simulation theory and a non-simulationist perceptual account. I argue that, if the extended mind adopts a simulation theory of action-understanding, it rejects representationalism. If it adopts a non-simulationist perceptual account of action-understanding, it rejects the classical sandwich view of the mind. (shrink)

We argue that the letter of the Extended Mind hypothesis can be accommodated by a strongly internalist, broadly Cartesian conception of mind. The argument turns centrally on an unusual but highly plausible view on the mark of the mental.

Pessoa'sThe Cognitive-Emotional Brain(2013) is an integrative approach to neuroscience that complements other developments in cognitive science, especially enactivism. Both accept complexity as essential to mind; both tightly integrate perception, cognition, and emotion, which enactivism unifies in its foundational concept of sense-making; and both emphasize that the spatial extension of mental processes is not reducible to specific brain regions and neuroanatomical connectivity. An enactive neuroscience is emerging.

The main claim of the famous paper “The Extended Mind”, written by Clark and Chalmers (CC), is that the mind could literally extend into the external world. Among the many opponents of this claim, Robert Rupert has raised two main objections against it. The first, depending on the acceptance or denial of the possible 4th feature the hypothesis of extended cognition (HEC) is either insignificant or implausible and the second, external cognitive states are so immensely (...) different from internal ones that they should be counted as distinct. In this paper, I will not only answer Rupert’s criticisms through system-respond and differences in R-properties, but I will, in the end, also respond to the criticisms on extended mind, which are based on the observation that it is not as groundbreaking as it first appeared to be, and claim that even if that is the case, it doesn’t posit a problem to its significance.

In 2008 the authors held Involving Interface, a lively interdisciplinary event focusing on issues of biological, sociocultural, and technological interfacing (see Acknowledgments). Inspired by discussions at this event, in this article, we further discuss the value of input from neuroscience for developing robots and machine interfaces, and the value of philosophy, the humanities, and the arts for identifying persistent links between human interfacing and broader ethical concerns. The importance of ongoing interdisciplinary debate and public communication on scientific and technical advances (...) is also highlighted. Throughout, the authors explore the implications of the extended mind hypothesis for notions of moral accountability and robotics. (shrink)

In his critique of the extended mind hypothesis, Robert Rupert suggests that we have no reason to move from the claim that cognition is deeply embedded in the environment to the more radical claim that, in some cases, cognition itself extends into the environment. In this paper, I argue that we have strong normative reasons to prefer the more radical extended mind hypothesis to Rupert’s modest embedded mind hypothesis. I take an agnostic (...) position on the metaphysical debate about the ultimate nature and location of the mind, and instead argue in favor of the extended mind framework on the basis of its ability to better capture normative concerns about the way we evaluate the cognitive capacities of learning disabled individuals. In light of the commitments of the embedded and extended mind frameworks, defenders of the embedded mind framework are committed to conclusions about learning-disabled individuals that we have good normative reason to reject, whereas the extended mind framework avoids such problematic conclusions. Thus, if we find these normative concerns persuasive, we have good reason to prefer the extended mind position. (shrink)

In this essay, I argue that the late ontology of Maurice Merleau-Ponty, in particular the system he began to develop in The Visible and the Invisible, can be conceived of as a form of Radical Enactive Cognition, as described by Hutto and Myin in Radicalizing Enactivism. I will begin by discussing Clark and Chalmers’ extended mind hypothesis, as well as the enactive view of consciousness proposed by Varela, Thompson, and Rosch in The Embodied Mind. However, neither (...) Clark and Chalmers’ extended mind hypothesis nor the enactive view of consciousness advanced by Varela et al. are radical enough to fully capture Merleau-Ponty’s late ontology. Inasmuch as Hutto and Myin’s formulation combines features of the extended mind thesis and enactivism, and expresses both in a sufficiently radical fashion, it overcomes the deficits of both theories and can serve as a translation, so to speak, of Merleau-Ponty’s “ontology of the flesh” into contemporary terms. In particular, their formulation makes explicit several central aspects of his theory: the intimate, mutually constitutive relationship between perceiver and perceived world, the equal weight given to the contributions of perceiver and world within this relationship, and the displacement of representational content from its central position in the understanding of consciousness. It is thus the ideal vehicle for demonstrating some perhaps unexpected ways in which Merleau-Ponty’s thought is compatible with contemporary conversations concerning the nature of mind. (shrink)

This book argues that conscious experience is sometimes extended outside the brain and body into certain kinds of environmental interaction and tool use. It shows that if one accepts that cognitive states can extend, one must also accept that consciousness can extend. The proponents of Extended Mind defend the former claim, but usually oppose the latter claim. The most important undertaking of this book is to show that this partition is not possible on pain of inconsistency. Pii (...) Telakivi presents three arguments for the hypothesis of Extended Conscious Mind, examines and answers the most common counterarguments, and introduces a novel means to interpret and apply the concept of constitution. She also addresses the tensions between analytic philosophy of mind and enactivism, and builds a bridge between two different traditions: on the one hand, extended mind, and on the other, enactivism and embodied mind—and maintains that a unifying approach is necessary for a theory about extended consciousness.

While the value of the extended mind hypothesis for human cognition is disputed, this paper examines the explanatory utility of the extended mind framework in the domain of AI systems, specifically the Google self-driving car. I argue that the cognitive architecture of the Google-car is best explained as an instance of extended cognition. The argument for this claim begins with a description of the Google-car’s cognitive architecture, including the indispensable role of “prior maps” in (...) its performance. I then argue that the hypothesis of extended cognition provides a better explanation of the Google-car’s performance than two rival, non-extended alternatives. Consideration of the Google-car also offers insight into whether driverless vehicles have achieved human-level competency in the cognitive skills required for driving, or instead remain “poor substitutes.”.

Humans are individuals qua objects, organisms and, putatively, minds. We are also social animals. We tend to value self-rule—i.e., the possession and exercise of the capacity or capacities that allow individuals to govern their lives. However, our sociality can call the possibility and value of such autonomy into question. The more we seem to be social animals, the less we seem to be capable of running our own lives. Empirical psychology has revealed surprising details about the extent to which our (...) minds are subject to social influence. Such influence is sometimes taken as a threat to self-rule. The debate over the Extended Mind Hypothesis (EMH) might seem to exacerbate the social threat to self-rule. If minds are spread across individuals, perhaps it no longer makes sense to speak of individual selves who may or may not rule themselves. I argue that no general threat to self-rule stems from human sociality. Further, the adoption of EMH is consistent with extensive attribution of psychological states to individuals, thus vouchsafing individual selves and autonomy. (shrink)

In recent years, philosophical developments of the notion of distributed and/or scaffolded cognition have given rise to the “extended mind” thesis. Against the popular belief that the mind resides solely in the brain, advocates of the extended mind thesis defend the claim that a significant portion of human cognition literally extends beyond the brain into the body and a heterogeneous array of physical props, tools, and cultural techniques that are reliably present in the environment in (...) which people grow, think, and act (Clark and Chalmers 1998; Clark 1997, 2003, 2008; Wilson 2004; Rowlands 1999, 2012; Menary 2007; Theiner 2011). However, as commentators who are friendly to the idea of distributed cognition have pointed out, the philosophical debate over extended cognition has predominantly focused on the impact of tools on our thinking while somewhat neglecting the distinctively social and cultural dimensions of cognitive scaffolding (Sterelny 2004, 2010; Caporael 1997a, 1997b; Smith and Semin 2004; Wilson 2005; Barnier et al. 2008; Sutton et al. 2010; Theiner, Allen, and Goldstone 2010). -/- To reorient the reigning paradigm, Hutchins (2010, 445) has recently proposed the “hypothesis of enculturated cognition” (HEnC) as an alternative to Clark’s (2003, 2008) largely individualistic vision of the extended mind. According to the HEnC, the “ecological assemblies of human cognition make pervasive use of cultural products” and are typically “assembled … in ongoing cultural practices” (ibid.). Cultural practices, for Hutchins, are essentially “the things people do in interaction with one another” (ibid., 440). My goal in this chapter is to follow up on Hutchins’s call to “spur the program forward” (ibid., 445), by generalizing Kirsh and Maglio’s (1994) distinction between pragmatic and epistemic actions from the level of individuals to the level of groups. The concept of a collective epistemic action refers to the ways in which groups of people actively change the structure of their social organization, with the epistemic goal of reshaping and augmenting their cognitive performance as integrated collectivities. By placing a renewed emphasis on the interactions between people, rather than between people and their tools, I hope to reconnect the cognitive-scientifically-driven “extended mind” thesis with complementary areas of social-scientific research in which groups are analyzed as the seats of action and cognition in their own right. In particular, the literature to which I aim to build a bridge in this paper is, on the one hand, certain segments of social and organizational psychology (Larson and Christensen 1993; Hinsz et al. 1997; Mohammed and Dumville 2001), and, on the other hand, theories of collective and institutional action (Ostrom 1990; List and Pettit 2011).

Two aspects of cognitive coupling, as brought forward in the Extended Mind Hypothesis, are discussed in this paper: how shall the functional coupling between the organism and some entity in his environment be spelled out in detail? What are the paradigmatic external entities to enter into that coupling? These two related questions are best answered in the light of an aetiological variety of functionalist argument that adds historical depth to the “active externalism” promoted by Clark and Chalmers (...) and helps to counter some of the core criticisms levelled against this view. Under additional reference to conceptual parallels between the Extended Mind Hypothesis and a set of heterodox theories in biology—environmental constructivism, niche construction, developmental systems theory—an argument for the grounding of environmentally extended cognitive traits in evolved biological functions is developed. In a spirit that seeks to integrate extended functionalism with views from cognitive integration and complementarity, it is argued that instances of environmental coupling should be understood as being constitutive to cognitive functions in either of two distinct ways. It is further argued that the historically and systematically prior environmental counterparts in that coupling are features of the natural environment. Language and linguistically imbued artefacts are likely to have descended from more basic relations that have an extension over the environment. (shrink)

I introduce the seven papers in this special issue, by Andy Clark, Je´roˆme Dokic, Richard Menary, Jenann Ismael, Sue Campbell, Doris McIlwain, and Mark Rowlands. This paper explains the motivation for an alliance between the sciences of memory and the extended mind hypothesis. It examines in turn the role of worldly, social, and internalized forms of scaffolding to memory and cognition, and also highlights themes relating to affect, agency, and individual differences.

Robert Rupert is well-known as a vigorous opponent of the hypothesis of extended cognition . His Cognitive Systems and the Extended Mind is a first-rate development of his "systems-based" approach to demarcating the mind. The results are impressive. Rupert's account brings much-needed clarity to the often-frustrating debate over HEC: much more than just an attack on HEC, he gives a compelling picture of why the debate matters.

The extended mind hypothesis (EMH) is the claim that the mind can and does extend beyond the human body. Adams and Aizawa (A&A) contend that arguments for EMH commit a ‘coupling constitution fallacy’. We deny that the master argument for EMH commits such a fallacy. But we think that there is an important question lurking behind A&A's allegation: under what conditions is cognition spread across a tightly coupled system? Building on some suggestions from Haugeland, we contend (...) that the system must exhibit a distinctive sort of semantic activity, semantic activity that the system as a whole takes responsibility for.

The hypothesis of extended cognition (HEC), or the claim that cognitive processes are not entirely organism-bound and can extend into the world, has received a barrage of criticism. Likewise, defenders of HEC have responded and even retreated into more moderate positions. In this paper, I trace the debate, rehearsing what I take to be the three strongest cases against HEC: nonderived content, causally natural kinds, and informational integration. I then argue that so far, the replies have been unsatisfactory, (...) mainly because they rest on tacit assumptions about the nature of ?human organisms,? which are the very subjects in question. One such reply, Clark's (2008) recent hypothesis of organism-centered cognition (HOC), is shown to be a particularly hasty retreat, specifically in terms of tackling the issue of informational integration. Namely, my position is that Clark concedes too quickly that the organism is the ?chief executor? of this cognitive function and I claim this on the grounds that (1) not all human organisms integrate information in the way Weiskopf (2008) argues they do, and (2) it is not impossible for external tools to be an informationally integrative component of a ?systemic whole.?

According to the hypothesis of extended phenomenal consciousness, although the material vehicles that realize phenomenal consciousness include neural elements, they are not restricted to such elements. There will be cases in which those material vehicles additionally include not only non-neural bodily elements, but also elements located beyond the skull and skin. In this paper, I examine two arguments for ExPC, one due to Noë and the other due to Kiverstein and Farina. Both of these arguments conclude that ExPC (...) is true on the basis of an analysis of sensory substitution, the phenomenon in which technological augmentation enables one sensory modality, for instance touch, to support the kind of environmental access and interaction ordinarily supported by a different sensory modality, for instance vision. I develop considerations which reveal that, as they stand, both of these arguments fall short. If the phenomenon of sensory substitution provides evidence for the truth of ExPC, it is not because of the specific arguments offered by these authors. (shrink)

This paper explores the relationship between several ideas about the mind and cognition. The hypothesis of extended cognition claims that cognitive processes can and do extend outside the head, that elements of the world around us can actually become parts of our cognitive systems. It has recently been suggested that the hypothesis of extended cognition is entailed by one of the foremost philosophical positions on the nature of the mind: functionalism, the thesis that mental (...) states are defined by their functional relations rather than by their physical constituents. Furthermore, it has been claimed that functionalism entails a version of extended cognition which is sufficiently radical as to be obviously false. I survey the debate and propose several ways of avoiding this conclusion, emphasizing the importance of distinguishing the hypothesis of extended cognition from the related notion of the extended mind.

Is the brain the biological substrate of consciousness? Most naturalistic philosophers of mind have supposed that the answer must obviously be «yes » to this question. However, a growing number of philosophers working in 4e (embodied, embedded, extended, enactive) cognitive science have begun to challenge this assumption, arguing instead that consciousness supervenes on the whole embodied animal in dynamic interaction with the environment. We call views that share this claim dynamic sensorimotor theories of consciousness (DSM). Clark (2009) a (...) founder and leading proponent of the hypothesis of the extended mind, demurs, arguing that as matter of fact the biology of consciousness doesn’t allow for a brain, body and world boundary crossing architecture. We begin by looking at one of the arguments for DSM, the variable neural correlates argument. We then outline two criticisms that Clark has made of this argument and endorse his criticisms. However we finish up by using the case of sensory substitution to argue that something of this argument for DSM nevertheless survives. We suggest that Clark ought to concede sensory substitution as a case in which the conscious mind extends. (shrink)

This paper examines the justification for the hypothesis of extended cognition. HEC claims that human cognitive processes can, and often do, extend outside our head to include objects in the environment. HEC has been justified by inference to the best explanation. Both advocates and critics of HEC claim that we can infer the truth value of HEC based on whether HEC makes a positive or negative explanatory contribution to cognitive science. I argue that IBE cannot play this epistemic (...) role. A serious rival to HEC exists with a differing truth value, and this invalidates IBEs for both the truth and the falsity of HEC. Explanatory value to cognitive science is not a guide to the truth value of HEC.Keywords: Extended mind; Extended cognition; Embedded cognition; Externalism; Inference to the best explanation; Functionalism.

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.

According to the extended mind thesis, cognitive processes are not confined to the nervous system but can extend beyond skin and skull to notebooks, iPhones, computers and such. The extended mind thesis is a metaphysical thesis about the material basis of our cognition. As such, whether the thesis is true can have implications for epistemological issues. Carter has recently argued that safety-based theories of knowledge are in tension with the extended mind hypothesis, since (...) the safety condition implies that there is an epistemic difference between subjects who form their beliefs via their biological capacities and between subjects who have extended their cognition. Kelp, on the other hand, has argued that a safety-based theory of knowledge can be correct only if the extended mind thesis is true. While these claims are not logically inconsistent, they do leave the safety theorist in an uncomfortable position. I will argue that safety-based theories of knowledge are not hostage to the truth of the extended mind thesis, and that once the safety condition is properly understood it is not in tension with the extended mind thesis.

This paper brings together two erstwhile distinct strands of philosophical inquiry: the extended mind hypothesis and the situationist challenge to virtue theory. According to proponents of the extended mind hypothesis, the vehicles of at least some mental states (beliefs, desires, emotions) are not located solely within the confines of the nervous system (central or peripheral) or even the skin of the agent whose states they are. When external props, tools, and other systems are suitably (...) integrated into the functional apparatus of the agent, they are partial bearers of her cognitions, motivations, memories, and so on. According to proponents of the situationist challenge to virtue theory, dispositions located solely within the confines of the nervous system (central or peripheral) or even the skin of the agent to whom they are attributed typically do not meet the normative standards associated with either virtue or vice (moral, epistemic, or otherwise) because they are too susceptible to moderating external variables, such as mood modulators, ambient sensibilia, and social expectation signaling. We here draw on both of these literatures to formulate two novel views – the embedded and extended character hypotheses – according to which the vehicles of not just mental states but longer-lasting, wider-ranging, and normatively-evaluable agentic dispositions are sometimes located partially beyond the confines of the agent’s skin.

Dominant views about the nature of health and disease in bioethics and the philosophy of medicine have presumed the existence of a fixed, stable, individual organism as the bearer of health and disease states, and as such, the appropriate target of medical therapy and ethical concern. However, recent developments in microbial biology, neuroscience, the philosophy of cognitive science, and social and personality psychology (Ickes...

The extended mind hypothesis (EMH) is the claim that the mind can and does extend beyond the human body. Adams and Aizawa (A&A) contend that arguments for EMH commit a ‘coupling constitution fallacy’. We deny that the master argument for EMH commits such a fallacy. But we think that there is an important question lurking behind A&A's allegation: under what conditions is cognition spread across a tightly coupled system? Building on some suggestions from Haugeland, we contend (...) that the system must exhibit a distinctive sort of semantic activity, semantic activity that the system as a whole takes responsibility for.

In 1998, Clark and Chalmers articulated and defended the extended mind hypothesis. They argued, against the backdrop of functionalism about the mind, and for the specific case of the mental state type belief, that it is possible for a person's mind to extend out-side the boundary of their body. Departing from the framework of Indo-analytic comparative philosophy, we show that the Advaita Vedanta School of classical Indian philosophy, against the backdrop of a specific form of (...) panpsychism, defended an account on which a person's conscious experience, during an act of perceptual knowledge, is located outside the boundary of their body. Using the work of Adams and Maher on how to respond to Adams and Aizawa's coupling-constitution fallacy, we argue that the Advaita Vedanta account of mind can be taken to generate what we call the mind extension hypothesis -- the view that consciousness can extend outside of the body in perception. Recognizing the problematic nature of panpsychism as a metaphysical view about consciousness, we close by following work by Itay Shani on the real combination problem. We argue that the Advaita Vedanta account of panpsychism, as a kind of cosmopsychism, allows for a response to the so-called real combination problem proposed by Coleman. (shrink)

Mangan’s hypothesis, that consciousness is an information-bearing medium, presents an alternative to Dennett’s brand of functionalism, and Dennett’s counterattacks have yet to address Mangan’s main assertion. The medium hypothesis does not entail Cartesian theater assumptions concerning the localization, causal status, and “filling in” of consciousness in the brain. In principle, it is compatible with distributed information transfer between different media, epiphenomenalism, and gaps in visual experience. However, Mangan’s strongest empirical argument, based on consciousness’ limited “bandwidth,” does not necessarily (...) show that transduction between media of different information-bearing capacities occurs between the brain and consciousness. The features of consciousness that he attributes to a lower bandwidth medium can be explained in terms of functional constraints on a single medium. Furthermore, empirical results showing gaps and anomalies in visual experience speak against consciousness being a medium. (shrink)

The hypothesis of extended cognition (HEC) claims that the cognitive processes that materially realise thinking are sometimes partially constituted by entities that are located external to an agent’s body in its local envi- ronment. We show how proponents of HEC need not claim that an agent must have a central nervous system, or physically instantiate processes organised in such a way as to play a causal role equivalent to that of the brain if that agent is to be (...) capable of cognition. Focusing on the case of spatial memory, we make our argument by taking a close look at the striking example of Physarum Polycephalum plasmodium (i.e., slime mould) which uses self- produced non-living extracellular slime trails to navigate its environment. We will argue that the use of exter- nalized spatial memory by basal organisms like Physarum is an example of extended cognition. Moreover, it is a possible evolutionary precursor to the use of internal spatial memory and recall in animals thus demonstrating how extended cognition may have emerged early in evolutionary history.

The Perceptual Hypothesis is that we sometimes see, and thereby have non-inferential knowledge of, others' mental features. The Perceptual Hypothesis opposes Inferentialism, which is the view that our knowledge of others' mental features is always inferential. The claim that some mental features are embodied is the claim that some mental features are realised by states or processes that extend beyond the brain. The view I discuss here is that the Perceptual Hypothesis is plausible if, but only if, (...) the mental features it claims we see are suitably embodied. Call this Embodied Perception Theory. I argue that Embodied Perception Theory is false. It doesn't follow that the Perceptual Hypothesis is implausible. The considerations which serve to undermine Embodied Perception Theory serve equally to undermine the motivations for assuming that others' mental lives are always imperceptible. (shrink)

Martin and Deutscher’s remarkable 1966 paper ‘Remembering’ still offers great riches to memory researchers across distinctive traditions, both in its methodological ambition (successfully marrying phenomenological and causal discourses) and in its content. In this short discussion, after briefly setting the paper in its context, we hone in on two live and under-explored issues which have gained attention recently under new labels – the extended mind hypothesis, and the constructive nature of memory. We suggest that Martin and Deutscher’s (...) causal analysis of memory is compatible with the idea that activities of remembering may be distributed across heterogeneous social and external resources, focussing in on their neglected example of creatures who ‘remember as we do’ as long as they carry round metal boxes which are given to them at birth. We then argue that the causal analysis is in some tension with the extent to which remembering is a constructive activity, because there may be no clear way to determine the appropriate ‘limits of accuracy’ within which a past event or experience must be represented.
