We very often grant that a person can gain knowledge on the basis of epistemic artifacts such as telescopes, microscopes and so on. However, this intuition threatens to undermine virtue reliabilism according to which one knows that p if and only if one’s believing the truth that p is the product of a reliable cognitive belief-forming process; in an obvious sense epistemic artifacts are not parts of one’s overall cognitive system. This is so, unless the extended (...) cognition hypothesis (HEC) is true. According to HEC when parts of the environment become properly coupled to the agent’s brain then they too can be considered constitutive parts of the overall cognitive mechanism—i.e. cognition potentially extends to the world surrounding the agent. Interestingly, HEC and the broader framework of virtue reliabilism share some intriguing similarities, which render these two views mutually supportive. Making these similarities explicit provides a principled account of the way in which our knowledge-conducive cognitive characters may extend beyond our natural cognitive capacities by incorporating epistemic artifacts.

Robert Rupert is well-known as an vigorous opponent of the hypothesis of extended cognition (HEC). 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.

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.

The Hypothesis of Extended Cognition (HEC)—that many cognitive processes are carried out by a hybrid coalition of neural, bodily and environmental factors—entails that the intentional states that are reasons for action might best be ascribed to wider entities of which individual persons are only parts. I look at different kinds of extended cognition and agency, exploring their consequences for concerns about the moral agency and personal responsibility of such extended entities. Can extended (...) entities be moral agents and bear responsibility for actions, in addition to or in place of the individuals typically held responsible? What does it mean to be autonomous when one’s cognition is influenced and supported by a milieu of environmental factors? To answer these questions, I explore strong parallels between HEC’s critique of individualism in cognition, and feminist critiques of individualist accounts of self, agency, and autonomy. This relational and social conception of autonomous agency, as scaffolded and supported (or undermined and impaired) by a milieu of social, relational, and normative factors, has important lessons for HEC. Drawing together these two visions of distributed and decentralized aspects of personhood highlights how cognition, action, and responsibility are inextricably linked. It also encourages a reconceptualization of all cognition and all concerns about responsibility for actions, not simply as sometimes extended around individuals, but as fundamentally communal, social, and normative, with individual cognition and individual moral responsibility being derivative special cases, not the paradigm examples. Individuals are merely one of many possible loci of cognition, action, and responsibility. (shrink)

In contemporary philosophy of the cognitive sciences, proponents of the ‘Hypothesis of Extended Cognition’ have focused on demonstrating how cognitive processes at times extend beyond the boundaries of the human body to include external physical devices. In recent years the HEC framework has been put to use in cases of “socially” extended cognition. The guiding intuition in this paper is that exploring the cognitive incorporations of genuinely social elements may advance HEC debates. (...) The paper provides an analysis of emotion regulation in ‘dyadic synchronic interaction’ between infant and caretaker and argues that some ‘socially extended’ cases of cognition cannot be captured with the HEC. Instead, the ‘Hypothesis of Emergent Extended Cognition’ is introduced that complements the HEC and helps in understanding how cognitive properties are sometimes irreducibly emergent, non-programmed properties of coupled social systems. It will be concluded that operating with the HEEC leads to both a more precise grip on the explanandum and to a more robust explanans. (shrink)

Philosophers and cognitive scientists alike have recently been interested in whether cognition extends beyond the boundaries of skin and skull and into the environment. However, the extended cognition hypothesis has suffered many objections over the past few decades. In this paper, I explore the option of control extending beyond the human boundary. My aim is to convince the reader of three things: (i) that control can be implemented in artifacts, (ii) that humans and artifacts can (...) form extended control systems, and (iii) that perhaps extended control ought to be preferred over extended cognition. Using the objections to extended cognition as constraints on my own extended theorizing and the example of autofocus systems in cameras, I decompose and localize the components of an autofocus system that realize the central properties of control from a plausible theory of control in the literature. I then provide criteria according to which control can be extended in a system. Finally, I consider how this theory of extended control ought to be preferred to theories of extended cognition. (shrink)

I argue that examining the explanatory power of the hypothesis of extended cognition (HEC) offers a fruitful approach to the problem of cognitive system demarcation. Although in the discussions on HEC it has become common to refer to considerations of explanatory power as a means for assessing the plausibility of the extended cognition approach, to date no satisfying account of explanatory power has been presented in the literature. I suggest that the currently most (...) prominent theory of explanation in the special sciences, James Woodward’s contrastive-counterfactual theory, and an account of explanatory virtues building on that theory can be used to develop a systematic picture of cognitive system demarcation in the psychological sciences. A major difference between my differential influence (DI) account and most other theories of cognitive extension is the cognitive systems pluralism implied by my approach. By examining the explanatory power of competing traditions in psychological memory research, I conclude that internalist and externalist classificatory strategies are characterized by different profiles of explanatory virtues and should often be considered as complementary rather than competing approaches. This suggests a deflationary interpretation of HEC. (shrink)

In this article we present an advanced version of Dual-PECCS, a cognitively-inspired knowledge representation and reasoning system aimed at extending the capabilities of artificial systems in conceptual categorization tasks. It combines different sorts of common-sense categorization (prototypical and exemplars-based categorization) with standard monotonic categorization procedures. These different types of inferential procedures are reconciled according to the tenets coming from the dual process theory of reasoning. On the other hand, from a representational perspective, the system relies on the (...) class='Hi'>hypothesis of conceptual structures represented as heterogeneous proxytypes. Dual-PECCS has been experimentally assessed in a task of conceptual categorization where a target concept illustrated by a simple common-sense linguistic description had to be identified by resorting to a mix of categorization strategies, and its output has been compared to human responses. The obtained results suggest that our approach can be beneficial to improve the representational and reasoning conceptual capabilities of standard cognitive artificial systems, and –in addition– that it may be plausibly applied to different general computational models of cognition. The current version of the system, in fact, extends our previous work, in that Dual-PECCS is now integrated and tested into two cognitive architectures, ACT-R and CLARION, implementing different assumptions on the underlying invariant structures governing human cognition. Such integration allowed us to extend our previous evaluation. (shrink)

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.

This article argues for a task-based approach to identifying and individuating cognitive systems. The agent-based extended cognition approach faces a problem of cognitive bloat and has difficulty accommodating both sub-individual cognitive systems ("scaling down") and some supra-individual cognitive systems ("scaling up"). The standard distributed cognition approach can accommodate a wider variety of supra-individual systems but likewise has difficulties with sub-individual systems and faces the problem of cognitive bloat. We develop a task-based variant (...) of distributed cognition designed to scale up and down smoothly while providing a principled means of avoiding cognitive bloat. The advantages of the task-based approach are illustrated by means of two parallel case studies: re-representation in the human visual system and in a biomedical engineering laboratory. (shrink)

We define a mathematical formalism based on the concept of an ‘‘open dynamical system” and show how it can be used to model embodied cognition. This formalism extends classical dynamical systems theory by distinguishing a ‘‘total system’’ (which models an agent in an environment) and an ‘‘agent system’’ (which models an agent by itself), and it includes tools for analyzing the collections of overlapping paths that occur in an embedded agent's state space. To illustrate the way (...) this formalism can be applied, several neural network models are embedded in a simple model environment. Such phenomena as masking, perceptual ambiguity, and priming are then observed. We also use this formalism to reinterpret examples from the embodiment literature, arguing that it provides for a more thorough analysis of the relevant phenomena. (shrink)

The concept of an extended cognitive system is central to contemporary studies of cognition. In the paper I analyze the place of the epistemic subject within the extended cognitive system. Is it extended as well? In answering this question I focus on the differences between the first and the second wave of arguments for the extended mind thesis. I argue that the position of Cognitive Integration represented by Richard Menary is (...) much more intuitive and fruitful in analyses of cognition and knowledge than the early argument formulated by Andy Clark and David Chalmers. Cognitive Integration is compatible with virtue epistemology of John Greco’s agent reliabilism. The epistemic subject is constituted by its cognitive character composed of an integrated set of cognitive abilities and processes. Some of these processes are extended, they are a manipulation of external informational structures and, as such, they constitute epistemic practices. Epistemic practices are normative; to conduct them correctly the epistemic subject needs to obey epistemic norms embedded in the cultural context. The epistemic subject is not extended because of the casual coupling with external informational artifacts which extend his mind from inside the head and into the world. Rather, cognitive practices constitute the subject’s mind, they transform his cognitive abilities, and this is what makes the mind and epistemic subject “extended”. (shrink)

The goal of perceptual systems is to allow organisms to adaptively respond to ecologically relevant stimuli. Because all perceptual inputs are ambiguous, perception needs to rely on prior knowledge accumulated over evolutionary and developmental time to turn sensory energy into information useful for guiding behavior. It remains controversial whether the guidance of perception extends to cognitive states or is locked up in a “cognitively impenetrable” part of perception. I argue that expectations, knowledge, and task demands can shape perception at (...) multiple levels, leaving no part untouched. The position advocated here is broadly consistent with the notion that perceptual systems strive to minimize prediction error en route to globally optimal solutions :181–204, 2013). On this view, penetrability should be expected whenever constraining lower-level processes by higher level knowledge is minimizes global prediction error. Just as Fodor feared cognitive penetration of perception threatens theory-neutral observation and the distinction between observation and inference. However, because theories themselves are constrained by the task of minimizing prediction error, theory-laden observation turns out to be superior to theory-free observation in turning sensory energy into useful information.

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.

Cognitive Science, Volume 45, Issue 11, November 2021.

This paper presents writing as an extended cognitive system comprised of brain, body, and the material form that is writing. Part I introduces the theoretical framework used for the analysis, Material Engagement Theory (MET), and the initial insights into writing systems gained by applying MET to Mesopotamian artifacts for numbers and writing. Part II discusses how writing as a material form has changed over time and why this material change reflects, accumulates, and distributes change in the behaviors (...) and brains of generations of writers. Part III explains why forms of writing used today are a visible form of language in being comprised of contrastive graphic features. Part IV argues against the idea that writing should be excluded from being considered as an extended cognitive system. On the contrary, considering writing from this perspective can provide new insights into the ways we use material forms—not just in writing but more broadly—to change our behaviors and brains, and their roles in intensifying and perpetuating those changes.

Robert Rupert argues against the view that human cognitive processes comprise elements beyond the boundary of the organism, developing a systems-based conception in place of this extended view. He also argues for a conciliatory understanding of the relation between the computational approach to cognition and the embedded and embodied views.

The complementary properties and functions of cognitive artifacts and other external resources are integrated into the human cognitive system to varying degrees. The goal of this paper is to develop some of the tools to conceptualize this complementary integration between agents and artifacts. It does so by proposing a multidimensional framework, including the dimensions of information flow, reliability, durability, trust, procedural transparency, informational transparency, individualization, and transformation. The proposed dimensions are all matters of degree and jointly they (...) constitute a multidimensional space in which situated cognitive systems can be located and have certain dimensional configurations. These dimensions provide a new perspective on the conditions for cognitive extension. They are, however, not meant to provide a set of necessary and sufficient conditions, but to provide a toolbox for investigating the degree and nature of the integration of agent and artifact into “new systemic wholes”. The higher a situated system scores on the proposed dimensions, the more functional integration occurs, and the more tightly coupled the system is. (shrink)

Extended and distributed cognition theories argue that human cognitive systems sometimes include non-biological objects. On these views, the physical supervenience base of cognitive systems is thus not the biological brain or even the embodied organism, but an organism-plus-artifacts. In this paper, we provide a novel account of the implications of these views for learning, education, and assessment. We start by conceptualising how we learn to assemble extended cognitive systems by internalising cultural norms and practices. (...) Having a better grip on how extended cognitive systems are assembled, we focus on the question: If our cognition extends, how should we educate and assess such extended cognitive systems? We suggest various ways to minimize possible negative effects of extending one’s cognition and to efficiently find and organise (online) information by adopting a virtue epistemology approach. Educational and assessment implications are foregrounded, particularly in the case of Danish students’ use of the Internet during exams. (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)

Cognitive science has been beset for thirty years by foundational disputes about the nature and extension of cognition—e.g. whether cognition is necessarily representational, whether cognitive processes extend outside the brain or body, and whether plants or microbes have them. Whereas previous philosophical work aimed to settle these disputes, I aim to understand what conception of cognition scientists could share given that they disagree so fundamentally. To this end, I develop a number of variations on traditional (...) conceptual explication, and defend a novel explication of cognition called the sensitive management hypothesis. -/- Since expert judgments about the extension of “cognition” vary so much, I argue that there is value in explication that accurately models the variance in judgments rather than taking sides or treating that variance as noise. I say of explications that accomplish this that they are ecumenically extensionally adequate. Thus, rather than adjudicating whether, say, plants can have cognitive processes like humans, an ecumenically adequate explication should classify these cases differently: human cognitive processes as paradigmatically cognitive, and plant processes as controversially cognitive. -/- I achieve ecumenical adequacy by articulating conceptual explications with parameters, or terms that can be assigned a number of distinct interpretations based on the background commitments of participants in a discourse. For example, an explication might require that cognition cause “behavior,” and imply that plant processes are cognitive or not depending on whether anything plants do can be considered “behavior.” Parameterization provides a unified treatment of embattled concepts by isolating topics of disagreement in a small number of parameters. -/- I incorporate these innovations into an account on which cognition is the “sensitive management of organismal behavior.” The sensitive management hypothesis is ecumenically extensionally adequate, accurately classifying a broad variety of cases as paradigmatically or controversially cognitive phenomena. I also describe an extremely permissive version of the sensitive management hypothesis, arguing that it has the potential to explain several features of cognitive scientific discourse, including various facts about the way cognitive scientists ascribe representations to cognitive systems.

The complex systems approach to cognitive science invites a new understanding of extended cognitive systems. According to this understanding, extended cognitive systems are heterogenous, composed of brain, body, and niche, non-linearly coupled to one another. This view of cognitive systems, as non-linearly coupled brain–body–niche systems, promises conceptual and methodological advances. In this article we focus on two of these. First, the fundamental interdependence among brain, body, and niche makes it possible to explain extended (...) cognition without invoking representations or computation. Second, cognition and conscious experience can be understood as a single phenomenon, eliminating fruitless philosophical discussion of qualia and the so-called hard problem of consciousness. What we call “extended phenomenological-cognitive systems” are relational and dynamical entities, with interactions among heterogeneous parts at multiple spatial and temporal scales. (shrink)

The ‘causal-constitution’ fallacy, the ‘cognitive bloat’ worry, and the persisting theoretical confusion about the fundamental difference between the hypotheses of embedded (HEMC) and extended (HEC) cognition are three interrelated worries, whose common point—and the problem they accentuate—is the lack of a principled criterion of constitution. Attempting to address the ‘causal-constitution’ fallacy, mathematically oriented philosophers of mind have previously suggested that the presence of non-linear relations between the inner and the outer contributions is sufficient for cognitive extension. (...) The abstract idea of non-linearity, however, can be easily misunderstood and has, in the past, led to incorrect and counterintuitive conclusions about what may count as part of one’s overall cognitive system. In order to prevent any further mistakes I revisit dynamical systems theory to study the nature of the continuous mutual interactions that give rise to the aforementioned non-linear relations. Moreover, focusing on these interactions will allow us to provide two distinct arguments in support of the ontological postulation of extended cognitive systems, as well as an objective criterion of constitution. Accordingly, I put forward a version of HEC that treats continuous mutual interactions (and the resultant non-linear relations) not just as sufficient but also as necessary for cognitive extension. Such a qualified version of HEC may exclude certain alleged cases of cognitive extension where the agent does not mutually interact with his artifacts (e.g., shopping lists and directory services), but it is immune both to the ‘causal-constitution’ fallacy and the ‘cognitive bloat’ worry, and it can be sharply distinguished from HEMC.

Mainstream epistemology has typically taken for granted a traditional picture of the metaphysics of mind, according to which cognitive processes (e.g. memory storage and retrieval) play out entirely within the bounds of the skull and skin. But this simple ‘intracranial’ picture is falling in- creasingly out of step with contemporary thinking in the philosophy of mind and cognitive science. Likewise, though, proponents of active exter- nalist approaches to the mind—e.g. the hypothesis of extended cognitition (HEC)—have proceeded (...) by and large without asking what epistemological ramifications should arise once cognition is understood as criss-crossing the bounds of brain and world. This paper aims to motivate a puzzle that arises only once these two strands of thinking are brought in contact with one another. In particular, we want to first highlight a kind of con- dition of epistemological adequacy that should be accepted by proponents of extended cognition; once this condition is motivated, the remainder of the paper demonstrates how attempts to satisfy this condition seem to inevitably devolve into a novel kind of epistemic circularity. At the end of the day, proponents of extended cognition have a novel epistemological puzzle on their hands. (shrink)

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.?

Given the metaphysical and explanatory stalemate between Embedded and Extended cognition, different authors proposed moral arguments to overcome such a deadlock in favor of EXT. Farina and Lavazza attribute to EXT and EMB a substantive moral content, arguing in favor of the former by virtue of its progressiveness and inclusiveness. In this treatment, I criticize four of their moral arguments. In Sect. 2, I focus on the argument from legitimate interventions and on the argument from extended agency. (...) Section 3 concerns the argument from better protection and the argument from better treatment. Sections 4 and 5 are dedicated to counterarguments against each respectively. By distinguishing between EXT and the extended view, I argue that it is sufficient to use this second version for directly addressing and evaluating moral problems on normative grounds, independently of the causal or constitutive cognitive influence of the external resource on the agents’ minds. Moreover, I argue that the arguments and assumptions used by EXT theorists do not foster values of progressiveness and inclusiveness. To conclude, in Sect. 6, I show that the analysis of each argument converges on the conclusion that EXT does not have substantive moral content and implications per se, since they always depend on further assumptions.

I respond to Karola Stotz's criticisms of my previously published challenges to the inference from developmental systems theory to an extended view of cognition.

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 terms "extended cognition" and the "extended mind" identify two strands of philosophical argument that are commonly subsumed under the general heading of active externalism. The present paper describes an integrated approach to understanding extended cognition and the extended mind—one that papers over the differences between these two, ostensibly distinct, forms of cognitive extension. As an added bonus, the paper describes how active externalism might be applied to the realm of non-cognitive phenomena, (...) thereby yielding an expansion in the theoretical and empirical scope of the active externalist enterprise. Both these points of progress stem from what is called the dispositional hypothesis. According to the dispositional hypothesis, extended cognition occurs when the mechanisms responsible for the manifestation of dispositional properties include components that lie beyond the borders of the thing to which the dispositional properties are ascribed. (shrink)

The philosophical case for extended cognition is often made with reference to ‘extended-memory cases’ ; though, unfortunately, proponents of the hypothesis of extended cognition as well as their adversaries have failed to appreciate the kinds of epistemological problems extended-memory cases pose for mainstream thinking in the epistemology of memory. It is time to give these problems a closer look. Our plan is as follows: in §1, we argue that an epistemological theory remains compatible (...) with HEC only if its epistemic assessments do not violate what we call ‘the epistemic parity principle’. In §2, we show how the constraint of respecting the epistemic parity principle stands in what appears to be a prima facie intractable tension with mainstream thinking about cases of propositional memory. We then outline and evaluate in §3 several lines of response. (shrink)

Presentations of the extended mind thesis are often ambiguous between two versions of that thesis. According to the first, the extension of mind consists in the supervenience base of human individuals’ mental states extending beyond the skull and into artifacts in the outside world. According to a second interpretation, human individuals sometimes participate in broader cognitive systems that are themselves the subjects of extended mental states. This ambiguity, I suggest, contributes to several of the most serious criticisms (...) of the extended mind thesis, for these criticisms only apply to the first interpretation of the thesis. In what follows, I argue that several significant objections to the extended mind thesis fail to undermine the latter interpretation of that thesis. Having defended the second interpretation, I argue that the extension of mind does not involve the extension of self. Consequently, the subject of extended mental states is not the same individual whose causal coupling with external artifacts gives rise to extended mentality. (shrink)

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)

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.

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 increasing popularity of artificial cognitive enhancements raises the issue of their impact on the agent’s personal autonomy, and issues pertaining to how the latter is to be secured. The extended mind thesis implies that mental states responsible for autonomous action can be partly constituted by the workings of cognitive artifacts themselves, and the question then arises of whether this commits one to embracing an extended agent thesis. My answer is negative. After briefly presenting the main (...) accounts on the conditions for autonomous agency, and analyzing how the latter can be protected from threats posed by the use of cognitive artifacts, I argue that autonomous agency is essentially tied to conscious experience and intentionality, which in turn can only be attributed to the human part of any extended cognitive system. I present both theoretical (conceptual) and practical arguments against recognizing the entire extended system, composed of one human and an artifact, as an autonomous agent. (shrink)

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.

According to the extended cognition hypothesis (henceforth ExC), there are conditions under which thinking and thoughts (or more precisely, the material vehicles that realize thinking and thoughts) are spatially distributed over brain, body and world, in such a way that the external (beyond-the-skin) factors concerned are rightly accorded fully-paid-up cognitive status.1 According to functionalism in the philosophy of mind, “what makes something a mental state of a particular type does not depend on its internal constitution, but (...) rather on the way it functions, or the role it plays, in the system of which it is a part” (Levin 2008). The respective fates of these two positions may not be independent of each other. The claim that ExC is in some way a form of, dependent on, entailed by, or at least commonly played out in terms of, functionalism is now pretty much part of the received view of things (see, e.g., Adams and Aizawa 2008; Clark and Chalmers 1998; Clark 2005, 2008, this volume a, b, forthcoming; Menary 2007; Rupert 2004; Sprevak manuscript; Wheeler forthcoming). Thus ExC might be mandated by the existence of functionally specified cognitive systems whose boundaries are located partly outside the skin. This is the position that Andy Clark has recently dubbed extended functionalism (Clark 2008, forthcoming; see also Wheeler forthcoming). (shrink)

In this paper I aim to offer one novel perspective on the effects of physical and social isolation on an individual in the period of COVID-19 pandemic. Namely, we can distinguish two standard approaches to studying such effects: psychological, which strives to identify emergence and effects of new external stressors on an individual, and legal and ethical, which evaluates justification and correctness of certain public strategies designed to combat the pandemic that jeopardize human rights, such as the right to freedom (...) of movement. The novel perspective, offered in this paper, should not replace any of these approaches, instead it will provide some amendments to them by putting in place a new theoretical framework. The focus of the paper will be on justifying two major assumptions of this novel approach – the assumption that individuals as cognitive systems and selves sometimes extend into the environment, and the assumption that this environment can be social, i.e. that individuals sometimes extend on cognitive resources of other people. If these assumptions can be well founded, some psychological effects of isolation could be reconceptualized as instances of the internal transformations of an individual who loses some of her parts. Also, adopting the view that individuals are socially extended cognitive systems would lead to recognizing novel legal and ethical issues with respect to forced social isolation – endangerment of personal rights pertaining to personal integrity and identity.

According to virtue epistemology, the main aim of education is the development of the cognitive character of students (Pritchard, 2014, 2016). Given the proliferation of technological tools such as ChatGPT and other LLMs for solving cognitive tasks, how should educational practices incorporate the use of such tools without undermining the cognitive character of students? Pritchard (2014, 2016) argues that it is possible to properly solve this ‘technology-education tension’ (TET) by combining the virtue epistemology framework with the (...) theory of extended cognition (EXT) (Clark and Chalmers, 1998). He argues that EXT enables us to consider tools as constitutive parts of the students’ cognitive system, thus preserving their cognitive character from technologically induced cognitive diminishment. The first aim of this paper is to show that this solution is not sufficient to solve the TET. Second, I aim to offer a complementary and more encompassing framework of tool-use to address the TET. Then, I apply it to the educational uses of ChatGPT as the most notable example of LLM, although my arguments can be extended to other generative AI systems. To do so, in Sect. 1.1, I present Pritchard’s framework of cognitive character and virtue epistemology applied in education, to which I am committed in this treatment. In Sects. 2 and 3, I respectively illustrate Pritchard’s (2014) solution to the TET, and I highlight the general limitations of his proposal. Thus, in Sect. 4.1 I characterize ChatGPT as a computational cognitive artifact using Fasoli’s (2017, 2018) taxonomy of cognitive artifacts. In Sect. 4.2, I introduce my proposal, which combines Pritchard’s account of virtue epistemology with Fasoli’s (2017, 2018) taxonomy of cognitive artifacts to address the TET. Finally, in Sect. 5.1, I present some epistemically virtuous uses of ChatGPT in educational contexts. To conclude, I argue in favor of a multidisciplinary approach for analyzing educational activities involving AI technologies such as ChatGPT. (shrink)

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)

The hypothesis of the Extended Cognition (ExCog), formulated by Clark and Chalmers (1998), aims to be a bold and new hypothesis about realisers of cognitive processes. It claims that sometimes cognitive processes extend above the limits of the skin and skull and include chunks of the environment as their partial realisers. One of the most pursuasive arguments in support of this assertion is the famous “parity argument” which calls upon functional similarities between extended (...) cognitive processes and relevant internal processes. This very kind of reasoning gave rise to several arguments against ExCog by way of comparing it to functionalism about the mental, which conclude that ExCog must be trivial, radical or unjustified. In this paper ExCog and the underlying parity principle will be defended against four different kinds of “functionalist” arguments. It will be argued that ExCog can be justified as a special form of functionalism, that it is not trivial nor entailed by the known versions of functionalism, and that the accusation of it being too radical is unwarranted.
