[Andy Clark] What is the relation between perceptual experience and the suite of sensorimotor skills that enable us to act in the very world we perceive? The relation, according to 'sensorimotor models' is tight indeed. Perceptual experience, on these accounts, is enacted via skilled sensorimotor activity, and gains its content and character courtesy of our knowledge of the relations between movement and sensory stimulation. I shall argue that this formulation is too extreme, and that it fails to accommodate the substantial firewalls, dis-integrations, and special-purpose streamings that form the massed strata of human cognition. In particular, such strong sensorimotor models threaten to obscure the computationally potent insensitivity of key information-processing events to the full subtleties of embodied cycles of sensing and moving. /// [Naomi Eilan] The strong sensorimotor account of perception gives self-induced movements two constitutive roles in explaining visual consciousness. The first says that self-induced movements are vehicles of visual awareness, and for this reason consciousness 'does not happen in the brain only'. The second says that the phenomenal nature of visual experiences is consists in the action-directing content of vision. In response I suggest, first, that the sense in which visual awareness is active should be explained by appeal to the role of attention in visual consciousness, rather than self-induced movements; and second, that the sense in which perceptual consciousness does not happen in the brain only should be explained by appeal to the relational nature of perceptual consciousness, appeal to which also shows why links with action cannot exhaust phenomenal content.

My question is: does phenomenal consciousness have a critical role in explaining the way conscious perceptions achieve objective import? I approach it through developing a dilemma I label ‘Burge’s Challenge’, which is implicit in his approach to perceptual objectivity. It says, crudely: either endorse the general structure of his account of how objective perceptual import is achieved, and give up on a role for consciousness. Or, relinquish Caused Representation, and possibly defend a role for consciousness. Someone I call Burge* holds we should embrace the first horn of the dilemma. A second response, roughly the relationalist approach, opts for the second horn. The third option, implicit in many current approaches to perceptual consciousness, is to reject the dilemma. The paper argues for a version of the second response. The key argument turns on the development of a sceptical challenge to justify the assumption that we perceive particular intrinsic property instantiations, rather than their structural equivalents. The suggestion will be that only the relationalist approach can meet it in the way we think it is met. If this is right, there is a prima facie case for taking relationalist responses to the dilemma seriously. I end with two objections to this response, which might be made by the real Burge in defence of opting for the first horn of the dilemma, and by phenomenal intentionalists in defence of rejecting the dilemma. I use discussion of these to highlight one of the main issues that should be pursued in order to make good the claim that we should embrace the horn of the dilemma that Burge* rejects.

A representative expression of current thinking on the ‘problem of consciousness’ runs as follows. There is one, impenetrably hard problem; and a host of soluble, and in this sense easy problems. The hard problem is: how could a physical system yield subjective states? How could there be something it is like to be a physical system? This problem corresponds to a concept of consciousness invariably labelled ‘phenomenal consciousness’. It is here, with respect to phenomenal consciousness, that we encounter an ‘explanatory gap’, where it is this gap that makes the problem so hard. Nothing we can say about the workings of a physical system could begin to explain the existence and nature of subjective, phenomenal feel.

To be a 'commonsense realist' is to hold that perceptual experience is (in general) an immediate awareness of mind-independent objects, and a source of direct knowledge of what such objects are like. Over the past few centuries this view has faced formidable challenges from epistemology, metaphysics, and, more recently, cognitive science. However, in recent years there has been renewed interest in it, due to new work on perceptual consciousness, objectivity, and causal understanding. This volume collects nineteen original essays by leading philosophers and psychologists on these topics. Questions addressed include: What are the commitments of commonsense realism? Does it entail any particular view of the nature of perceptual experience, or any particular view of the epistemology of perceptual knowledge? Should we think of commonsense realism as a view held by some philosophers, or is there a sense in which we are pre-theoretically committed to commonsense realism in virtue of the experience we enjoy or the concepts we use or the explanations we give? Is commonsense realism defensible, and if so how, in the face of the formidable criticism it faces? Specific issues addressed in the philosophical essays include the status of causal requirements on perception, the causal role of perceptual experience, and the relation between objective perception and causal thinking. The scientific essays present a range of perspectives on the development, phylogenetic and ontogenetic, of the human adult conception of perception

Sometime around their first birthday most infants begin to engage in relatively sustained bouts of attending together with their caretakers to objects in their environment. By the age of 18 months, on most accounts, they are engaging in full-blown episodes of joint attention. As developmental psychologists (usually) use the term, for such joint attention to be in play, it is not sufficient that the infant and the adult are in fact attending to the same object, nor that the one’s attention cause the other’s. The latter can and does happen much earlier, whenever the adult follows the baby’s gaze and homes in on the same object as the baby is attending to; or, from the age of six months, when babies begin to follow the gaze of an adult. We have the relevant sense of joint attention in play only when the fact that both child and adult are attending to the same object is, to use Sperber and Wilson’s (1986) phrase, ‘mutually manifest’. Psychologists sometimes speak of such jointness as a case of attention being ‘shared’ by infant and adult, or of a ‘meeting of minds’ between infant and adult, all phrases intended to capture the idea that when joint attention occurs everything about the fact that both subjects are attending to the same object is out in the open, manifest to both participants.

Suppose you are a blindsighted subject and an experimenter sitting opposite you says of an object in your functionally blind field ‘that peach looks delicious’. Unless you move your head to encompass the object within your normal field of vision you will not know which object she is talking about. Suppose now she reverts to the strategy used by neurophsychologists who work with blindsighted subjects and simply tells you that there is an object there and asks you either to reach for it or guess its shape, colour and so forth. If you are one of the well-trained blindsighted subjects who have been worked over for many years by psychologists you may well be able to do so, while denying you have any visual experience of the object and insisting you are only guessing. And, in concurrence with the existential formulation the experimenter now uses, instead of the demonstrative, it is natural to think that your singular reference, based on your perceptual input, is descriptive, as in ‘the object she maintains is there’ or ‘the object I am guessing about’ or ‘the object in my blind field’, etc.

Spatial Representation presents original, specially written essays by leading psychologists and philosophers on a fascinating set of topics at the intersection of these two disciplines. They address such questions as these: Do the extraordinary navigational abilities of birds mean that these birds have the same kind of grip on the idea of a spatial world as we do? Is there a difference between the way sighted and blind subjects represent the world 'out there'? Does the study of brain-injured subjects, such as 'blind seers', tell us anything about the working of normal spatial consciousness? The essays are arranged into five sections, each of which reflects a central area of research into spatial cognition, and opens with a short introduction by the editors, designed to facilitate cross-disciplinary reading. The volume as a whole offers a rich and compelling expression of the view that to advance our understanding of the way we represent the external world it is necessary to draw on both philosophical and psychological approaches.

Wittgenstein formulates the paradox of gestalt switches thus: ‘What is incomprehensible is that nothing, and yet everything has changed, after all. That is the only way to put it’. In the course of isolating what I take to be the best of the various solutions to the paradox explored by Wittgenstein, the following claims are defended: (a) A significant strand in Wittgenstein’s own formulation of, and solution to, the paradox can best be understood as a response to three specific claims made by the Gestalt psychologist Kohler. (b) The most promising avenue Wittgenstein explored in his many attempts to resolve the paradox gives perceptual attention a constitutive role in the solution (c) This role is best elaborated, partially, by appeal to information processing theories of attention. (d) There are good reasons to think that the kind of solution to the paradox this yields would have been welcomed by Wittgenstein.

Perceptual experience, that paradigm of subjectivity, constitutes our most immediate and fundamental access to the objective world. At least, this would seem to be so if commonsense realism is correct — if perceptual experience is (in general) an immediate awareness of mind-independent objects, and a source of direct knowledge of what such objects are like. Commonsense realism raises many questions. First, can we be more precise about its commitments? Does it entail any particular conception of the nature of perceptual experience and its relation to perceived objects, or any particular view of the way perception yields knowledge? Second, what explains the apparent intuitive appeal of commonsense realism? Should we think of it as a kind of folk theory held by most human adults or is there a sense in which we are pre-theoretically committed to it — in virtue of the experience we enjoy or in virtue of the concepts we use or in virtue of the explanations we give? Third, is commonsense realism defensible, in the face of formidable challenges from epistemology, metaphysics and cognitive science? The project of the present volume is to advance our understanding of these issues and thus to shed light on the commitments and credentials of commonsense realism. As you may have guessed from the title, the volume also aims to highlight the key role the concept of causation plays in these debates. Central issues to be addressed include the status and nature of causal requirements on perception, the causal role of perceptual experience, and the relation between objective perception and causal thinking — issues that, as many chapters in the volume bring out, are inseparable from concerns with the very nature of causation.

Let us label this claim the Basic Datum. What I shall call the Minimal Constraint is the claim, 'An account of the states of mind of subjects credited with knowledgeable thoughts about a mind-independent world must show how the intrinsic properties of such states of mind could yield such knowledge'. That is, a theory of thought must explain the Basic Datum. ;The Basic Datum may seen an obvious truism, and so too may the Minimal Constraint. But if 'obvious' means 'undisputed', neither of these claims is that. First, to say that is acquiring knowledge about the world we are restricted to the immediate deliverances of our psychological states, is to make a major concession to a central plank in the sceptic's argument against the possibility of knowing a mind-independent world. Many think that to deny the sceptic's conclusion we must reject this claim. Causal theories of reference, theories of direct acquaintance and so forth are often formulated with this aim in mind. ;Secondly, the Basic Datum is formulated from the first person perspective; as is the Minimal Constraint. Adoption of this perspective is necessary for generating scepticism; and many think that in order to rebut scepticism we must abandon the first person perspective when explaining the nature of knowledge. A fortiori, they hold that an explanation of the nature of a subjects psychological states when thinking knowledgeable thoughts about the world should not be constrained by questions raised from the first person perspective. ;Doubts of the first kind about the validity of the Constraint fall under what I shall call the Reference Debate; and doubts of the second kind under what I shall call the Reflectivity Debate. Throughout I shall be concerned with these debates as they apply to the phenomenology of experience-embedded thoughts, where by phenomenology I mean no more than the intrinsic properties of the state of mind of subjects credited with such thoughts. More specifically, I shall focus on the state of mind corresponding to the demonstrative component in experience-embedded thoughts expressible by such utterances as, "This is square". I shall refer to such states of mind as 'demonstrative states of mind'; and to experience-embedded thoughts containing a demonstrative component as 'demonstrative thoughts'. All my examples will be of vision-based demonstrative thought, but nothing is supposed to hang on this
