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

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

It is commonly held that our thoughts, beliefs, desires and feelings - the mental phenomena that we instantiate - are constituted by states and processes that occur inside our head. The view known as externalism, however, denies that mental phenomena are internal in this sense. The mind is not purely in the head. Mental phenomena are hybrid entities that straddle both internal state and processes and things occurring in the outside world. The development of externalist conceptions of the mind is (...) one of the most controversial, and arguably one of the most important, developments in the philosophy of mind in the second half of the twentieth century. Yet, despite its significance most recent work on externalism has been highly technical, clouding its basic ideas and principles. Moreover, very little work has been done to locate externalism within philosophical developments in both analytic and continental traditions. In this book, Mark Rowlands aims to remedy both these problems and present for the reader a clear and accessible introduction to the subject grounded in wider developments in the history of philosophy. Rowlands shows that externalism has significant and respectable historical roots that make it much more important than a specific eruption that occurred in late twentieth-century analytic philosophy.

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

The paper looks at the intersection of extended cognition and social cognition. The central claim is that the mechanisms of shared intentionality can equally be considered as coupling mechanisms of cognitive extension into the social domain. This claim will be demonstrated by investigating a detailed example of cooperative action, and it will be argued that such cases imply that socially extended cognition is not only about cognitive vehicles, but that content must additionally to be taken into account. It is finally (...) outlined how social content externalism can in principle be grounded in socially extended cognition. (shrink)

The extended mind thesis (EM) asserts that some cognitive processes are (partially) composed of actions consisting of the manipulation and exploitation of environmental structures. Might some processes at the root of social cognition have a similarly extended structure? In this paper, I argue that social cognition is fundamentally an interactive form of space management—the negotiation and management of ‘‘we-space”—and that some of the expressive actions involved in the negotiation and management of we-space (gesture, touch, facial and whole-body expressions) drive basic (...) processes of interpersonal understanding and thus do genuine social-cognitive work. Social interaction is a kind of extended social cognition, driven and at least partially constituted by environmental (non-neural) scaffolding. Challenging the Theory of Mind paradigm, I draw upon research from gesture studies, developmental psychology, and work on Moebius Syndrome to support this thesis. (shrink)

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

We argue that embedded cognition provides an argument against Jaegwon Kim’s neural reduction of mental causation. Because some mental, or at least psychological processes have to be cast in an externalist way, Kim’s argument can be said to lead to the conclusion that mental causation is as safe as any other form of higher-level of causation.

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

Where does the mind stop and the rest of the world begin? The question invites two standard replies. Some accept the demarcations of skin and skull, and say that what is outside the body is outside the mind. Others are impressed by arguments suggesting that the meaning of our words "just ain't in the head", and hold that this externalism about meaning carries over into an externalism about mind. We propose to pursue a third position. We advocate a very different (...) sort of externalism: an _active externalism_, based on the active role of the environment in driving cognitive processes.

According to a widely accepted constraint on the content of intentions, here called the exclusivity constraint, one cannot intend to perform another agent’s action, even if one might be able to intend that she performs it. For example, while one can intend that one’s guest leaves before midnight, one cannot intend to perform her act of leaving. However, Deborah Tollefsen’s (2005) account of joint activity requires participants to have intentions-in-action (in John Searle’s (1983) sense) that violate this constraint. I argue (...) that the exclusivity constraint should not be accepted as an unconditional constraint on the contents of intentions-in-action: one may intend to perform a basic action that belongs both to oneself and to another agent. Based on the phenomenology of tool use, I first argue that intentions-in-action of one’s basic actions may be technologically extended, meaning that their contents are not restricted to concern the agent’s bodily movements. In analogy with this, I then argue that the phenomenology of some skillful joint activities supports the idea that one’s basic intentions-in-action may be socially extended, in violation of the widely accepted exclusivity constraint. Tollefsen’s account is specifically constructed to account for the joint activities of infants and toddlers who lack the capacity to think of others as planning agents and grasp their plan-like intentions (a capacity required by Michael Bratman’s (1992, 1993, 2009a, b) influential account of joint activity). At the end of the paper, I raise some doubts regarding the extent to which infants and toddlers have socially extended intentions-in-action. (shrink)

This chapter discusses the flaws of Clark’s extended mind hypothesis. Clark’s hypothesis assumes that the nature of the processes internal to an object has nothing to do with whether that object carries out cognitive processing. The only condition required is that the object is coupled with a cognitive agent and interacts with it in a certain way. In making this tenuous connection, Clark commits the most common mistake extended mind theorists make; alleging that an object becomes cognitive once it is (...) connected to a cognitive agent is a “coupling-constitution fallacy.” From this fallacy, many hastily proceed to the conclusion that the object or process constitutes part of the agent’s cognitive apparatus or cognitive processing.

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

Since its inception some fifty years ago, cognitive science has seen a number of sea changes. Perhaps the best known is the development of connectionist models of cognition as an alternative to classical, symbol-based approaches. A more recent - and increasingly influential - trend is that of dynamical-systems-based, ecologically oriented models of the mind. Researchers suggest that a full understanding of the mind will require systematic study of the dynamics of interaction between mind, body, and world. Some argue that this (...) new orientation calls for a revolutionary new metaphysics of mind, according to which mental states and processes, and even persons, literally extend into the environment. This book is a guide to this movement in cognitive science. Each chapter tackles either a specific area of empirical research or specific sector of the conceptual foundation underlying this research.

What is the mind? Is consciousness a process in the brain? How do our minds represent the world? Philosophy of Mind: Classical and Contemporary Readings is a grand tour of writings on these and other perplexing questions about the nature of the mind. The most comprehensive collection of its kind, the book includes sixty-three selections that range from the classical contributions of Descartes to the leading edge of contemporary debates. Extensive sections cover foundational issues, the nature of consciousness, and the (...) nature of mental content. Three of the selections are published here for the first time, while many other articles have been revised especially for this volume. Each section opens with an introduction by the editor. Philosophy of Mind is suitable for students at all levels and also for general readers. (shrink)

In Supersizing the Mind, Andy Clark argues that the human mind is not bound inside the head but extends into body and environment.

In the philosophy of language, conceptual role semantics (hereafter CRS) is a theory of what constitutes the meanings possessed by expressions of natural languages, or the propositions expressed by their utterance. In the philosophy of mind, it is a theory of what constitutes the contents of psychological attitudes, such as beliefs or desires. CRS comes in a variety of forms, not always clearly distinguished by commentators. Such versions are known variously as functional/causal/computational role semantics, and more broadly as use-theories of (...) meaning. Nevertheless, all are united in seeking the meaning or content of an item, not in what it is made of, nor in what accompanies or is associated with it, but in what is done with it, the use it is put to. Roughly, according to CRS, the meaning or propositional content of an expression or attitude is determined by the role it plays in a person’s language or in her cognition. Currently, many view CRS as the main rival to theories that take notions such as truth or reference as central (for example, Davidson 2001), although the relationship between the two is not straightforward. The following outlines the main varieties of CRS, provides a cursory survey of its history, introduces the central arguments offered in its favor, and provisionally assesses how the variants fair against a number of prominent criticisms.

Multiple Realizability (MR) must still be regarded as one of the principal arguments against type reductionist accounts of higher-order properties and their special laws. Against this I argue that there is no unique MR but rather a multitude of MR categories. In a slogan: MR is itself “multi-realized”. If this is true then we cannot expect one unique reductionist strategy against MR as an anti-reductionist argument. The main task is rather to develop a taxonomy of the wide variety of MR (...) cases and to sketch possible reductionist answers for each class of cases. The paper outlines some first steps in this direction. (shrink)

That about sums up what is wrong with Clark's view.

According to Conceptual Role Semantics ("CRS"), the meaning of a representation is the role of that representation in the cognitive life of the agent, e.g. in perception, thought and decision-making. It is an extension of the well known "use" theory of meaning, according to which the meaning of a word is its use in communication and more generally, in social interaction. CRS supplements external use by including the role of a symbol inside a computer or a brain. The uses appealed (...) to are not just actual, but also counterfactual: not only what effects a thought does have, but what effects it would have had if stimuli or other states had differed. The view has arisen separately in philosophy (where it is sometimes called "inferential," or "functional" role semantics) and in cognitive science (where it is sometimes called "procedural semantics"). The source of the view is Wittgenstein (1953) and Sellars, but the source in contemporary philosophy is a series of papers by Harman (see his 1987) and Field (1977). Other proponents in philosophy have included Block, Horwich, Loar, McGinn and Peacocke (1992). In cognitive science, they include Woods (1981) and Miller and Johnson-Laird (1976).
