Sensorimotor enactivism takes perceptual experience to be constituted by a kind of attunement to sensorimotor contingencies – law‐like relations between sensory inputs and bodily activity. The chemical senses have traditionally been construed as especially simple and passive, and a number of philosophers have argued that flavour and smell are problem cases for the sensorimotor approach. In this article, I respond to these objections to the sensorimotor approach, and in doing so offer the beginnings of a sensorimotor account of the chemical (...) senses. (shrink)

Much attention has recently been paid to the idea, which I label ‘External World Acquaintance’ (EWA), that the phenomenal character of perceptual experience is partially constituted by external features. One motivation for EWA which has received relatively little discussion is its alleged ability to help deal with the ‘Explanatory Gap’ (e.g. Fish 2008, 2009, Langsam 2011, Allen 2016). I provide a reformulation of this general line of thought, which makes clearer how and when EWA could help to explain the specific (...) phenomenal nature of visual experience. In particular, I argue that by focusing on the different kinds of perceptual actions that are available in the case of visual spatial vs. colour perception, we get a natural explanation for why we should expect the specific nature of colour phenomenology to remain less readily intelligible than the specific nature of visual spatial phenomenology.

Is action-guiding vision cognitively penetrable? More specifically, is the visual processing that guides our goal-directed actions sensitive to semantic information from cognitive states? This paper critically examines a recent family of arguments whose aim is to challenge a widespread and influential view in philosophy and cognitive science: the view that action-guiding vision is cognitively impenetrable. I argue, in response, that while there may very well be top–down causal influences on action-guiding vision, they should not be taken to be an instance (...) of cognitive penetration. Assuming otherwise is to assign a computational role to the influencing states that they cannot perform. Although questions about cognitive penetrability are ultimately empirical, the issues addressed in this paper are largely philosophical. The discussion here highlights an important set of considerations that help better understand the relations between cognition, vision, and action. (shrink)

Consciousness and Mind presents David Rosenthal's influential work on the nature of consciousness. Central to that work is Rosenthal's higher-order-thought theory of consciousness, according to which a sensation, thought, or other mental state is conscious if one has a higher-order thought that one is in that state. The first four essays develop various aspects of that theory. The next three essays present Rosenthal's homomorphism theory of mental qualities and qualitative consciousness, and show how that theory fits with and helps sustain (...) the HOT theory. A crucial feature of homomorphism theory is that it individuates and taxonomizes mental qualities independently of the way we're conscious of them, and indeed independently of our being conscious of them at all. So the theory accommodates the qualitative character not only of conscious sensations and perceptions, but also of those which fall outside our stream of consciousness. Rosenthal argues that, because this account of mental qualities makes no appeal to consciousness, it enables us to dispel such traditional quandaries as the alleged conceivability of undetectable quality inversion, and to disarm various apparent obstacles to explaining qualitative consciousness and understanding its nature. Six further essays build on the HOT theory to explain various important features of consciousness, among them the complex connections that hold in humans between consciousness and speech, the self-interpretative aspect of consciousness, and the compelling sense we have that consciousness is unified. Two of the essays, one an extended treatment of homomorphism theory, appear here for the first time. There is also a substantive introduction, which draws out the connections between the essays and highlights their implications. (shrink)

While philosophers of mind have been arguing over the status of mental representations in cognitive science, cognitive scientists have been quietly engaged in studying perception, action, and cognition without explaining them in terms of mental representation. In this book, Anthony Chemero describes this nonrepresentational approach, puts it in historical and conceptual context, and applies it to traditional problems in the philosophy of mind. Radical embodied cognitive science is a direct descendant of the American naturalist psychology of William James and John (...) Dewey, and follows them in viewing perception and cognition to be understandable only in terms of action in the environment. Chemero argues that cognition should be described in terms of agent-environment dynamics rather than in terms of computation and representation. After outlining this orientation to cognition, Chemero proposes a methodology: dynamical systems theory, which would explain things dynamically and without reference to representation. He also advances a background theory: Gibsonian ecological psychology, "shored up" and clarified. Chemero then looks at some traditional philosophical problems through the lens of radical embodied cognitive science and concludes that the comparative ease with which it resolves these problems, combined with its empirical promise, makes this approach to cognitive science a rewarding one. "Jerry Fodor is my favorite philosopher," Chemero writes in his preface, adding, "I think that Jerry Fodor is wrong about nearly everything." With this book, Chemero explains nonrepresentational, dynamical, ecological cognitive science as clearly and as rigorously as Jerry Fodor explained computational cognitive science in his classic work The Language of Thought.

Early modern empiricists thought that the nature of perceptual experience is given by citing the object presented to the mind in that experience. Hallucination and illusion suggest that this requires untenable mind-dependent objects. Current orthodoxy replaces the appeal to direct objects with the claim that perceptual experience is characterized instead by its representational content. This paper argues that the move to content is problematic, and reclaims the early modern empiricist insight as perfectly consistent, even in cases of illusion, with the (...) realist contention that these direct objects of perception are the persisting mind-independent physical objects we all know and love.

Much of the discussion of Naive Realism about veridical experience has focused on a consequence of adopting it—namely, disjunctivism about perceptual experience. However, the motivations for being a Naive Realist in the first place have received relatively little attention in the literature. In this paper, I will elaborate and defend the claim that Naive Realism provides the best account of the phenomenal character of veridical experience.

Many philosophers are skeptical about disjunctivism —a theory of perceptual experience which holds roughly that a situation in which I see a banana that is as it appears to me to be and one in which I have a hallucination as of a banana are mentally completely different. Often this skepticism is rooted in the suspicion that such a view cannot adequately account for the bad case—in particular, that such a view cannot explain why what it’s like to have a (...) hallucination can be exactly like what it’s like to have a veridical experience, that it cannot explain why the hallucination I have in the bad case is subjectively indistinguishable from the kind of experience I have in the good case, and that it cannot offer a viable account of the nature of hallucination. -/- In this paper, I argue that a proper formulation of disjunctivism can avoid these objections. Disjunctivism should be formulated as the weakest claim required to preserve its primary motivation, viz., Naïve Realism—the view that veridical experience fundamentally consists in the subject perceiving entities in her environment. And the weakest claim required to preserve Naïve Realism allows for many sorts of commonalities across the good and hallucinatory cases, commonalities that can be marshaled in responding to the objections. Most importantly, disjunctivism properly formulated is compatible with “positive” accounts of the nature of hallucination. (shrink)

How do questions concerning consciousness and phenomenal experience relate to, or interface with, questions concerning plans, knowledge and intentions? At least in the case of visual experience the relation, we shall argue, is tight. Visual perceptual experience, we shall argue, is fixed by an agent’s direct unmediated knowledge concerning her poise (or apparent poise) over a currently enabled action space. An action space, in this specific sense, is to be understood not as a fine-grained matrix of possibilities for bodily movement, (...) but as a matrix of possibilities for pursuing and accomplishing one’s intentional actions, goals and projects. If this is correct, the links between planning, intention and perceptual experience are tight, while (contrary to some recent accounts invoking the notion of ‘sensorimotor expectations’) the links between embodied activity and perceptual experience, though real, are indirect. What matters is not bodily activity itself, but our practical knowledge (which need not be verbalized or in any way explicit) of our own possibilities for action. Such knowledge, selected, shaped and filtered by the grid of plans, goals, and intentions, plays, we argue, a constitutive role in explaining the content and character of visual perceptual experience.

The unifying theme of these thirteen essays is understanding.

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.The basic assumption is that vision depends on the eye which is connected to the brain. The (...) author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision—and what this book is about. (shrink)

A common objection to sense-datum theories of perception is that they cannot give an adequate account of the fact that introspection indicates that our sensory experiences are directed on, or are about, the mind-independent entities in the world around us, that our sense experience is transparent to the world. In this paper I point out that the main force of this claim is to point out an explanatory challenge to sense-datum theories.

The enactive approach offers a distinctive view of how mental life relates to bodily activity at three levels: bodily self-regulation, sensorimotor coupling, and intersubjective interaction. This paper concentrates on the second level of sensorimotor coupling. An account is given of how the subjectively lived body and the living body of the organism are related via dynamic sensorimotor activity, and it is shown how this account helps to bridge the explanatory gap between consciousness and the brain. Arguments by O'Regan, Noë, and (...) Myin that seek to account for the phenomenal character of perceptual consciousness in terms of ‘bodiliness’ and ‘grabbiness’ are considered. It is suggested that their account does not pay sufficient attention to two other key aspects of perceptual phenomenality: the autonomous nature of the experiencing self or agent, and the pre-reflective nature of bodily self-consciousness.

Many current neurophysiological, psychophysical, and psychological approaches to vision rest on the idea that when we see, the brain produces an internal representation of the world. The activation of this internal representation is assumed to give rise to the experience of seeing. The problem with this kind of approach is that it leaves unexplained how the existence of such a detailed internal representation might produce visual consciousness. An alternative proposal is made here. We propose that seeing is a way of (...) acting. It is a particular way of exploring the environment. Activity in internal representations does not generate the experience of seeing. The out- side world serves as its own, external, representation. The experience of seeing occurs when the organism masters what we call the gov- erning laws of sensorimotor contingency. The advantage of this approach is that it provides a natural and principled way of accounting for visual consciousness, and for the differences in the perceived quality of sensory experience in the different sensory modalities. Sev- eral lines of empirical evidence are brought forward in support of the theory, in particular: evidence from experiments in sensorimotor adaptation, visual “filling in,” visual stability despite eye movements, change blindness, sensory substitution, and color perception.

Physical objects are such things as stones, tables, trees, people and other animals: the persisting macroscopic constituents of the world we live in. therefore expresses a commonsense commitment to physical realism: the persisting macroscopic constituents of the world we live in exist, and are as they are, quite independently of anyone.

The disjunctive theory of perception claims that we should understand statements about how things appear to a perceiver to be equivalent to statements of a disjunction that either one is perceiving such and such or one is suffering an illusion (or hallucination); and that such statements are not to be viewed as introducing a report of a distinctive mental event or state common to these various disjoint situations. When Michael Hinton first introduced the idea, he suggested that the burden of (...) proof or disproof lay with his opponent, that what was needed was to show that our talk of how things look or appear to one..

To the familiar idea of an undetectable spectrum inversion some have added the idea of inverted earth. This new combination of ideas is even harder to make coherent, particularly as it applies to a supposed inversion of black and white counteracted by an environmental switch of these. Black and white exhibit asymmetries in their connections with illumination, shadow and visibility, which rule out their being reversed. And since the most saturated yellow is light and the most saturated blue dark, yellow (...) and blue could not be reversed unless light and dark could be. The difficulties suggest some more general morals for how to think of the role of 'qualia' in colour perception. (shrink)

John Campbell investigates how consciousness of the world explains our ability to think about the world; how our ability to think about objects we can see depends on our capacity for conscious visual attention to those things. He illuminates classical problems about thought, reference, and experience by looking at the underlying psychological mechanisms on which conscious attention depends.

This paper is a response to the 26 commentaries on my paper "Facing Up to the Problem of Consciousness". First, I respond to deflationary critiques, including those that argue that there is no "hard" problem of consciousness or that it can be accommodated within a materialist framework. Second, I respond to nonreductive critiques, including those that argue that the problems of consciousness are harder than I have suggested, or that my framework for addressing them is flawed. Third, I address positive (...) proposals for addressing the problem of consciousness, including those based in neuroscience and cognitive science, phenomenology, physics, and fundamental psychophysical theories.

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible , and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and arguments developed earlier to defend (...) a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

In this important book, Susan Hurley sheds new light on consciousness by examining its relationships to action from various angles. She assesses the role of agency in the unity of a conscious perspective, and argues that perception and action are more deeply interdependent than we usually assume. A standard view conceives perception as input from world to mind and action as output from mind to world, with the serious business of thought in between. Hurley criticizes this picture, and considers how (...) the interdependence of perceptual experience and agency at the personal level (of mental contents and norms) may emerge from the subpersonal level (of underlying causal processes and complex dynamic feedback systems). Her two-level view has wide implications, for topics that include self-consciousness, the modularity of mind, and the relations of mind to world. The self no longer lurks hidden somewhere between perceptual input and behavioral output, but reappears out in the open, embodied and embedded in its environment. Hurley traces these themes from Kantian and Wittgensteinian arguments through to intriguing recent work in neuropsychology and in dynamic systems approaches to the mind, providing a bridge from mainstream philosophy to work in other disciplines. Consciousness in Action is unique in the range of philosophical and scientific work it draws on, and in the deep criticism it offers of centuries-old habits of thought. (shrink)

Critics have long complained that naive realism cannot adequately account for perceptual illusion. This complaint has a tendency to ally itself with the aspersion that naive realism is hopelessly out of touch with vision science. Here I offer a partial reply to both complaint and aspersion. I do so by showing how careful reflection on a simple, empirically grounded model of illusion reveals heterodox ways of thinking about familiar illusions which are quite congenial to the naive realist.

A phenomenal concept is the concept of a particular type of sensory or perceptual experience, where the notion of experience is understood phenomenologically. A recent and increasingly influential idea in philosophy of mind suggests that reflection on these concepts will play a major role in the debate about conscious experience, and in particular in the defense of physicalism, the thesis that psychological truths supervene on physical truths. According to this idea—I call it the phenomenal concept strategy —phenomenal concepts are importantly (...) different from other concepts, and arguments against physicalism fatally neglect to take this difference into account. This paper divides the phenomenal concept strategy into a number of different versions, and argues that no version of the strategy is successful. The paper ends by contrasting the phenomenal concept strategy with a rival strategy—I call it the missing concept strategy . I suggest that the missing concept strategy presents a more plausible response to the issues about physicalism and experience. (shrink)

and apply it to various examples of neural plasticity in which input is rerouted intermodally or intramodally to nonstandard cortical targets. In some cases but not others, cortical activity ‘defers’ to the nonstandard sources of input. We ask why, consider some possible explanations, and propose a dynamic sensorimotor hypothesis. We believe that this distinction is important and worthy of further study, both philosophical and empirical, whether or not our hypothesis turns out to be correct. In particular, the question of how (...) the distinction should be explained is linked to explanatory gap issues for consciousness. Comparative and absolute explanatory gaps should be distinguished: why does neural activity in a particular area of cortex have this qualitative expression rather than that, and why does it have any qualitative expression at all? We use the dominance/deference distinction to address the comparative gaps, both intermodal and intramodal. We do so not by inward scrutiny but rather by expanding our gaze to include relations between brain, body and environment. (shrink)

Color experience is structured. Some ?unique? colors (red, green, yellow, and blue) appear as ?pure,? or containing no trace of any other color. Others can be considered as a mixture of these colors, or as ?binary colors.? According to a widespread assumption, this unique/binary structure of color experience is to be explained in terms of neurophysiological structuring (e.g., by opponent processes) and has no genuine explanatory basis in the physical stimulus. The argument from structure builds on these assumptions to argue (...) that colors are not properties of surfaces and that color experiences are neural processes without environmental counterparts. We reconsider the argument both in terms of its logic and in the light of recent models in vision science which point at environment-involving patterns that may be at the basis of the unique/binary structure of color experience. We conclude that, in the light of internal and external problems which arise for it, the argument from structure fails. (shrink)

Recent attempts to show that functional processing entails the presence of phenomenal consciousness have failed to deliver the kind of answers to the “problems of consciousness” that anti-materialists insist the functionalist must provide. I will illustrate this by focusing on the claims that there is a special “Hard Problem” of consciousness and an “explanatory gap” between functional and phenomenal facts. I then argue that if we supplement the functionalist stories with a relationalist conception of phenomenal properties, we can begin to (...) see the shape of a naturalistic theory of phenomenal consciousness that will provide intuitively compelling responses to these problems.

Block (1995) famously warns against the confusion of.

Naturalism as a guiding philosophy for modern science both disavows any appeal to the supernatural or anything else transcendent to nature, and repudiates any philosophical or religious authority over the workings and conclusions of the sciences. A longstanding paradox within naturalism, however, has been the status of scientific knowledge itself, which seems, at first glance, to be something that transcends and is therefore impossible to conceptualize within scientific naturalism itself. In Articulating the World, Joseph Rouse argues that the most pressing (...) challenge for advocates of naturalism today is precisely this: to understand how to make sense of a scientific conception of nature as itself part of nature, scientifically understood. Drawing upon recent developments in evolutionary biology and the philosophy of science, Rouse defends naturalism in response to this challenge by revising both how we understand our scientific conception of the world and how we situate ourselves within it.

This paper argues that it is possible to combine enactivism and ecological psychology in a single post-cognitivist research framework if we highlight the common pragmatist assumptions of both approaches. These pragmatist assumptions or starting points are shared by ecological psychology and the enactive approach independently of being historically related to pragmatism, and they are based on the idea of organic coordination, which states that the evolution and development of the cognitive abilities of an organism are explained by appealing to the (...) history of interactions of that organism with its environment. It is argued that the idea of behavioral or organic coordination within the enactive approach gives rise to the sensorimotor abilities of the organism, while the ecological approach emphasizes the coordination at a higher-level between organism and environment through the agent’s exploratory behavior for perceiving affordances. As such, these two different processes of organic coordination can be integrated in a post-cognitivist research framework, which will be based on two levels of analysis: the subpersonal one and the personal one. If this proposal is on the right track, this may be a promising first step for offering a systematized and consistent post-cognitivist approach to cognition that retain the full potential of both enactivism and ecological psychology.

Hurley’s is a difficult book to work through—partly because of its length and the complexity of its arguments, but also because each of the ten essays of which it is composed has a rather different starting point and focus, and because few of her arguments achieve real closure. Essay 2 discusses competing interpretations of Kant, essay 4 articulates nonconceptual forms of self-consciousness, essay 5 offers fresh interpretations of commissurotomy patients’ behavior, essay 6 develops an objection to Wittgenstein on rule following, (...) essay 8 attacks an alleged assumption of externalism, and chapter 10 explores the possibility of combining a “motor theory” and a “control theory” of perception. This is a very rich brew, and at least half the challenge this book presents consists in discerning its central argument and conclusion with enough precision to bring criticism to bear. (shrink)

The inference from conceivability to possibility has been challenged in numerous ways. One of these ways is the so-called phenomenal concept strategy, which has become one of the main strategies against the conceivability argument against physicalism. However, David Chalmers has recently presented a dilemma for the phenomenal concept strategy, and he has argued that no version of the strategy can succeed. In this paper, I examine the dilemma, and I argue that there is a way out of it. I conclude (...) that Chalmers has not posed any serious problem for the phenomenal concept strategy to succeed in blocking the conceivability argument. In doing so, my aim is not only to show that Chalmers’s argument has not refuted the phenomenal concept strategy, but also to clarify what any version of the strategy should achieve in order to be successful.
