In this thesis I seek to advance our understanding of what intuitions are. I argue that intuitions are experiences of a certain kind. In particular, they are experiences with representational content, and with a certain phenomenal character. -/- In Chapter 1 I identify our target and provide some important reliminaries. Intuitions are mental states, but which ones? Giving examples helps: a person has an intuition when it seems to her that torturing the innocent is wrong, or that if something is (...) red it is coloured. We can also provide an initial characterisation of the state by saying that it has representational content, often causes belief, and appears to justify belief. In addition, there is something it is like to have an intuition: intuition has a certain phenomenal character. -/- Some argue that intuition does not explain anything which cannot be explained by other mental states. One version of this view takes intuition to reduce to belief. In Chapter 2 I argue that this entails that agents are rationally criticisable in situations where we know they are not, and that such views are therefore untenable. A parallel argument shows that the corresponding approach to perception fails. This suggests a similarity in nature: both intuition and perception are experiences. -/- Others take intuition to reduce to a disposition to have a belief. In Chapter 3 I consider a line of argument against such views, find it unsuccessful, and present two new arguments. One is likely to be dialectically ineffective. The other suffers no such weakness: it shows that the proposed reduction fails. As before, the argument also applies to perception, and suggests that intuition and perception are both experiences. -/- In the remainder of the thesis I develop an account of intuition as an experience. I distinguish between content-specific and attitude-specific phenomenology, and argue that intuition lacks the former (Chapter 4), but has the latter (Chapter 5). This allows us to say what intuition is: it is is an experience with representational content and with attitude-specific phenomenology of a certain kind. -/- In Chapter 6 I put this account of intuition to use. When a person has a perceptual or intuitional experience, I argue that simply having the experience is what makes the subject justified in believing what the experience represents. Moreover, what explains that intuition and perception can justify belief in this way is precisely their phenomenal character. (shrink)

A persistent methodological problem in primate social cognition research has been how to determine experimentally whether primates represent the internal goals of other agents or just the external goals of their actions. This is an instance of Daniel Povinelli’s more general challenge that no experimental protocol currently used in the field is capable of distinguishing genuine mindreading animals from their complementary behavior-reading counterparts. We argue that current methods used to test for internal-goal attribution in primates do not solve Povinelli’s problem. (...) To overcome the problem, a new type of experimental approach is needed, one which is supported by an alternative theoretical account of animal mindreading, called the appearance-reality mindreading (ARM) theory. We provide an outline of the ARM theory and show how it can be used to design a novel way to test for internal-goal attribution in chimpanzees. Unlike protocols currently in use, the experimental design presented here has the power, in principle and in practice, to distinguish genuine mindreading chimpanzees from those who predict others’ behavior solely on the basis of behavioral/environmental cues. Our solution to Povinelli’s problem has important consequences for a similar debate in developmental psychology over when preverbal infants should be credited with the ability to attribute internal goals. If what we argue for here in the case of nonhuman primates is sound, then the clearest tests for internal-goal attribution in infants will be those that test for attributions of discrepant or ‘false’ perceptions.

This is a bibliography of books and articles on consciousness in philosophy, cognitive science, and neuroscience over the last 30 years. There are three main sections, devoted to monographs, edited collections of papers, and articles. The first two of these sections are each divided into three subsections containing books in each of the main areas of research. The third section is divided into 12 subsections, with 10 subject headings for philosophical articles along with two additional subsections for articles in cognitive (...) science and neuroscience. Of course the division is somewhat arbitrary, but I hope that it makes the bibliography easier to use. This bibliography has first been compiled by Thomas Metzinger and David Chalmers to appear in print in two philosophical anthologies on conscious experience . From 1995 onwards it has been continuously updated by Thomas Metzinger, and now is freely available as a PDF-, RTF-, or HTML-file. This bibliography mainly attempts to cover the Anglo-Saxon and German debates, in a non-annotated, fully formatted way that makes it easy to "cut and paste" from the original file. To a certain degree this bibliography also contains items in other languages than English and German - all submissions in other languages are welcome. Last update of current version: July 13th, 2001.

This is a very selective survey of developments in epistemology, concentrating on work from the past twenty years that is of interest to philosophers of science. The selection is organized around interesting connections between distinct themes. I first connect issues about skepticism to issues about the reliability of belief-acquiring processes. Next I connect discussions of the defeasibility of reasons for belief to accounts of the theory-independence of evidence. Then I connect doubts about Bayesian epistemology to issues about the content of (...) perception. The last detailed connection is between considerations of the finiteness of cognition and epistemic virtues. To connect the connections I end by briefly discussing the pressure that consideration of social roles in the transmission of belief puts on the purposes of epistemology. (shrink)

It is widely agreed that perceptual experience is a form of intentionality, i.e., that it has representational content. Many philosophers take this to mean that like belief, experience has propositional content, that it can be true or false. I accept that perceptual experience has intentionality; but I dispute the claim that it has propositional content. This claim does not follow from the fact that experience is intentional, nor does it follow from the fact that experiences are accurate or inaccurate. I (...) end by considering the relationship between this question and the question of whether experience has non-conceptual content. (shrink)

Perceptual content is conceptual. In this paper, some arguments against this thesis are examined and rebutted. The Richness argument, that we could not have concepts for all the colours, is queried: Doesn't the Munsell system give us such concepts? The argument that we can perceive colours and shapes without possessing the relevant concepts is rebutted: we cannot do this, but the kind of concept-possession that is relevant here is not intellectual but perceptual.

Maps, notes, descriptions, diagrams, flowcharts, photographs, paintings, and prints, all, in one way or another, manage to be about things or stand for them. This article looks at three ways in which philosophers have explained the way that pictures represent the world. It starts by describing some leading perceptual accounts and then surveys contemporary content and structural alternatives.

This paper contrasts three different schemes of reference relevant to understanding systems of perceptual representation: a location-based system dubbed "feature-placing", a system of "visual indices" referring to things called "proto-objects", and the full sortal-based individuation allowed by a natural language. The first three sections summarize some of the key arguments (in Clark, 2000) to the effect that the early, parallel, and pre-attentive registration of sensory features itself constitutes a simple system of nonconceptual mental representation. In particular, feature integration--perceiving something as (...) being both F and G, where F and G are sensible properties registered in distinct parallel streams--requires a referential apparatus. Section V. reviews some grounds for thinking that at these earliest levels this apparatus is location-based: that it has a direct and nonconceptual means of picking out places. Feature-placing is contrasted with a somewhat more sophisticated system that can identify and track four or five "perceptual objects" or "proto-objects", independently of their location, for as long as they remain perceptible. Such a system is found in Zenon Pylyshyn's fascinating work on "visual indices", in Dana Ballard's notion of deictic codes, and in Kahneman, Treisman, and Wolfe's accounts of systems of evanescent representations they call "object files". Perceptual representation is a layered affair, and I argue that it probably includes both feature-placing and proto-objects. Finally, both nonconceptual systems are contrasted with the full-blooded individuation allowed in a natural language. (shrink)

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.

A representationalist-friendly introduction to representationalism which covers a number of central problems and objections.

Nuestro interés en el contenido mental no-conceptual es, principalmente, la articulación de una versión sustantiva (no-trivial) de esta clase de contenido en la experiencia perceptual. El debate acerca del contenido no-conceptual ha girado, en su mayor parte, alrededor de su existencia; y los argumentos que se han ofrecido en su favor abogan por una versión no sustantiva según la cual el contenido no-conceptual es aquel que no satisface ciertos requisitos conceptuales. Así, para desarrollar una versión sustantiva del contenido mental no-conceptual (...) hemos apelado a la versión de la experiencia perceptual de propiedades espaciales ofrecida por Evans (1982 cap. 6). A partir de esto desarrollamos un nuevo argumento a favor del contenido no-conceptual de la experiencia perceptual que lo vincula a la actividad característica de la experiencia perceptual. Por último, exponemos uno de los ataques de McDowell (1996) a la noción de contenido no-conceptual y presentamos nuestras réplicas a este ataque, mostrando su insuficiencia. Al mostrar que la crítica de McDowell no es exitosa, consideramos que podríamos tener una versión del contenido no-conceptual de la experiencia que es inmune a esta línea de argumentación. (shrink)

According to Milner and Goodale’s dual visual systems (DVS) theory, a division obtains between visual consciousness and motor action, in that the visual system producing conscious vision (the ventral stream) is distinct from the one guiding action (the dorsal stream). That there would be this division is often taken (by Andy Clark and others) to undermine the folk view on how consciousness and action relate. However, even if this division obtains, this leaves open the possibility that con- scious ventral information (...) is often transmitted to the uncon- scious dorsal stream and then used to guide action, a possibility seeming to preserve a significant role for consciousness in action. This article assesses this possibility. In course of doing so, we will review those arguments recently having been made against the DVS view on how visual consciousness and action relate (ones due to, e.g., Briscoe and Schwenkler, or Schenk and McIntosh). What we will find is that, if we properly analyze the data upon which these arguments are based, we are still left with the impression that the DVS view is largely correct; i.e., it is only rarely that visual experience guides action.

Since Tolman’s paper in 1948, psychologists and neuroscientists have argued that cartographic representations play an important role in cognition. These empirical findings align with some theoretical works developed by philosophers who promote a pluralist view of representational vehicles, stating that cognitive processes involve representations with different formats. However, the inferential relations between maps and representations with different formats have not been sufficiently explored. Thus, this paper is focused on the inferential relations between cartographic and linguistic representations. To that effect, we (...) appeal to heterogeneous inference with ordinary maps and sentences. In doing so, we aim to build a model to bridge the gap between cartographic and linguistic thought. (shrink)

According to the recent Perceptual Confidence view, perceptual experiences possess not only a representational content, but also a degree of confidence in that content. The motivations for this view are partly phenomenological and partly epistemic. We discuss both the phenomenological and epistemic motivations for the view, and the resulting account of the interface between perceptual experiences and degrees of belief. We conclude that, in their present state of development, orthodox accounts of perceptual experience are still to be favoured over the (...) perceptual confidence view. (shrink)

A great number of investigations suggest that cognition involves both linguistic and cartographic representations. These researches have motivated a pluralist conception of cognition; also, they have been used to clarify how maps differ from linguistic representations. However, the computational processes underlying the interphase between both kinds of representations deserve further attention. In this paper, I argue that, despite their differences, cartographic representations coexist and interact with linguistic representations in interesting ways.

According to a certain kind of naïve or folk understanding of physical matter, everyday ‘solid’ objects are composed of a homogeneous, gap-less substance, with sharply defined boundaries, which wholly fills the space they occupy. A further claim is that our perceptual experience of the environment represents or indicates that the objects around us conform to this sort of conception of physical matter. Were this further claim correct, it would mean that the way that the world appears to us in experience (...) conflicts with the deliverances of our best current scientific theories in the following respect: perceptual experience would be intrinsically misleading concerning the structure of physical matter. I argue against this further claim. Experience in itself is not committed to, nor does it provide evidence for, any such conception of the nature of physical matter. The naïve/folk conception of matter in question cannot simply be ‘read-off’ from perceptual appearances. (shrink)

Deafferented subjects, while lacking proprioceptive awareness of much of their bodies, are nevertheless able to use their bodies in basic action. Sustained visual contact with the body parts of which they are no longer proprioceptively aware enables them to move these parts in a controlled way. This might be taken to straightforwardly show that proprioceptive awareness is inessential to bodily action. I, however, argue that this is not the case. Proprioceptive awareness figures essentially in our self-conscious unity as practical subjects. (...) Recognizing this allows us to better understand the nature of the impairment with which deafferented subjects live. (shrink)

It is widely held in contemporary philosophy of mind that states with underived representational content are ipso facto psychological states. This view—the Content View—underlies a number of interesting philosophical projects, such as the attempt to pick out a psychological level of explanation, to demarcate genuinely psychological from non-psychological states, and to limn the class of states with phenomenal character. The most detailed and influential theories of underived representation in philosophy are the tracking theories developed by Fodor, Dretske, Millikan and others. (...) Tracking theorists initially hoped to ‘naturalize’ underived representation by showing that although it is distinctively psychological it is not irreducibly so, yet they ended up developing theories of representation that by their own lights don’t pick out a distinctively psychological phenomenon at all. Burge sets out to develop a theory of underived representation that does pick out a distinctively psychological phenomenon. His theory promises to vindicate the Content View and the various philosophical projects that depend on it. In this paper I argue that Burge’s theory dementalizes representation for the same reason tracking theories do: These theories hold that representations are states with underived accuracy conditions, yet such states are found in all sorts of mindless systems, like plants.

The main thesis of this paper is that two prevailing theories about cognitive penetration are too extreme, namely, the view that cognitive penetration is pervasive and the view that there is a sharp and fundamental distinction between cognition and perception, which precludes any type of cognitive penetration. These opposite views have clear merits and empirical support. To eliminate this puzzling situation, we present an alternative theoretical approach that incorporates the merits of these views into a broader and more nuanced explanatory (...) framework. A key argument we present in favor of this framework concerns the evolution of intentionality and perceptual capacities. An implication of this argument is that cases of cognitive penetration must have evolved more recently and that this is compatible with the cognitive impenetrability of early perceptual stages of processing information. A theoretical approach that explains why this should be the case is the consciousness and attention dissociation framework. The paper discusses why concepts, particularly issues concerning concept acquisition, play an important role in the interaction between perception and cognition. (shrink)

In its classical form, epiphenomenalism is the view that conscious mental events have no physical effects: while physical events cause mental events, the opposite is never true. Unlike classical epiphenomenalism, contemporary forms do not hold that conscious men­ tal states always lack causal efficacy, only that they are epiphenomenal relative to certain kinds of action, ones we pre-theoretically would have thought consciousness to causally contribute to. Two of these contemporary, empirically based challenges to the efficacy of the mental are the (...) focus of this chapter. The first, originating in research by Libet, has been interpreted as showing that the neural events initiating voluntary actions precede our conscious willing of them, meaning the conscious will cannot be what causes them. The second challenge, originating in studies by Milner and Goodale, consist of instances in which the content of visual consciousness and motor action dissociate, casting doubt on the intuitive view that visual consciousness guides visually based motor action.

This paper argues that perception is a mode of engagement with individuals and their determinate properties. Perceptual content involves determinate properties in a way that relies on our conceptual capacities no less than on the properties. The “richness” of perceptual experience is explained as a distinctive individual and property involving content. This position is developed in three steps: (i) novel phenomenological description of lived experience; (ii) detailed reconstruction of Gareth Evans’ proposal that we are capable of genuinely singular thought that (...) involves individuals under modes of presentation; (iii) re-consideration of the re-identification condition on conceptual contents. (shrink)

I criticise a recent variety of argument for the representational theory of experience, which holds that the very idea of perceptual experience entails the representational view. I argue that the representational view is not simply obvious, nor is it contained in the mere idea of the world looking some way. I also clarify and re-present an argument against the representational view due to Charles Travis.

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)

Blindsight is a kind of residual vision found in people with lesions to V1. Subjects with blindsight typically report no visual awareness, but they are nonetheless able to make above-chance guesses about the shape, location, color and movement of visual stimuli presented to them in their blind field. A different kind of blindsight, sometimes called type 2 blindsight, is a kind of residual vision found in patients with V1 lesions in the presence of some residual awareness. Type 2 blindsight differs (...) from ordinary visual experience in lacking the particularity, transparency and fine-grainedness often taken to be essential to visual experience, at least in veridical cases. I argue that the case of type 2 blindsight provides a counterexample to the view that these characteristics are essential to veridical visual experience and that this gives us reason to resist the view that visual experience is essentially a perceptual relation to external objects. In the second part of the paper I argue that the case of type 2 blindsight yields important insights into the effects of attentional modulation on perceptual content and that cases of attentional modulation of appearance are not at odds with the view that the phenomenology of visual experience flows from its content.

I develop a Russellian representationalist account of size experience that draws importantly from contemporary vision science research on size perception. The core view is that size is experienced in ‘body-scaled’ units. So, an object might, say, be experienced as two eye-level units high. The view is sharpened in response to Thompson’s (forthcoming) Doubled Earth example. This example is presented by Thompson as part of an argument for a Fregean view of size experience. But I argue that the Russellian view I (...) develop handles the Doubled Earth example in a natural and illuminating way, thereby avoiding the need to posit irreducible experiential ‘modes of presentation’. I also address a kind of neo-Fregean ‘reference-fixing’ view of size experience, that shares features with the Russellian view developed. I give reasons for favoring the latter. Finally, I argue that Peacocke’s claim that spatial experience is ‘unit free’ is not persuasive. (shrink)

I distinguish between two claims of transparency of experiences. One claim is weaker and supported by phenomenological evidence. This I call the transparency datum. Introspection of standard perceptual experiences as well as bodily sensations is consistent with, indeed supported by, the transparency datum. I formulate a stronger transparency thesis that is entailed by representationalism about experiential phenomenology. I point out some empirical consequences of strong transparency in the context of representationalism. I argue that pain experiences, as well as some other (...) similar experiences like itches, tickles, orgasms, hedonic valence, etc., are not transparent in this strong sense. Hence they constitute empirical counterexamples to representationalism. Given that representationalism is a general metaphysical doctrine about all experiential phenomenology for good reasons, I conclude that representationalism about phenomenal consciousness is false. Then, I outline a general framework about how the introspection of phenomenal qualities in perceptual experience works in light of the transparency datum, but consistent with the rejection of strong transparency. The result is a form of qualia realism that is naturalist and intentionalist, and has close affinities to the adverbialist views developed in the latter part of the last century. I then apply this framework to pain experiences and their bodily locations. (shrink)

The overall aim of this two-part article is to provide a supplement to ability theories of practice in terms of a defense of the following thesis: In situations of social interaction, individuals’ ability to act appropriately sometimes depends on their exercise of the ability directly to perceive normative states. In this Part I, I introduce ability theories of practice and motivate my thesis. Furthermore, I offer an analysis of normative states as response-dependent properties. Last, I work out and defend an (...) account of direct perception that is compatible with individuals being able directly to perceive various everyday phenomena. Drawing on this account, I show in part II, that normative states are sometimes directly perceptible too. (shrink)

A recent debate in Kant scholarship concerns the role of concepts in Kant's theory of perception. Roughly, proponents of a conceptualist interpretation argue that for Kant, the possession of concepts is a prior condition for perception, while nonconceptualist interpreters deny this. The debate has two parts. One part concerns whether possessing empirical concepts is a prior condition for having empirical intuitions. A second part concerns whether Kant allows empirical intuitions without a priori concepts. Outside of Kant interpretation, the contemporary debate (...) about conceptualism concerns whether perception requires empirical concepts. But, as I argue, the debate about whether Kant allows intuitions without empirical concepts does not show whether Kant is a conceptualist. Even if Kant allows intuitions without empirical concepts, it could still be that a priori concepts are required. While the debate could show that Kant is a conceptualist, I argue it does not. Finally, I sketch a novel way that the conceptualist interpreter might win the debate—roughly, by arguing that possessing a priori concepts is a prior condition for having appearances. (shrink)

In recent years, many philosophers have supposed that perceptual representations have propositional content. A prominent rationale for this supposition is the assumption that perceptions may justify beliefs, but this rationale can be doubted. This rationale may be doubted on the grounds that there do not seem to be any viable characterizations of the belief-justifying propositional contents of perceptions. An alternative is to model perceptual representations as marks in a perceptual similarity space. A mapping can be defined between points in perceptual (...) similarity space and points in an objective quality space. The correctness of perceptual representation can then be defined as a kind of accuracy of mapping rather than as the truth of a proposition. The phenomenon of seeing-as can be accounted for as a matter of the location of marks in perceptual similarity space relative to other marks in perceptual similarity space. Perceptual representations, on this account, will not justify beliefs, but they may nonetheless guide judgment. (shrink)

I discuss the relation between egocentric spatial representation and the capacity for bodily activity, with specific reference to Merleau-Ponty.

In this paper I argue that a principal argument in favor of the existence of non-conceptual content (henceforth NCC) fails. That is, I do not accept that considerations regarding the richness of our perceptual experiences support the existence of NCC. I argue instead that the existence of NCC is empirically motivated. Here is an outline of the paper. First, I set out the distinction between conceptual content and NCC as we understand it. Second, I consider the richness argument (RA), and (...) argue that it fails. I argue in particular that RA (or RA-style arguments) are either self-defeating or confl ict with reasonably established accounts of early perceptual processing. Third, I tackle a residual phenomenological puzzle and offer a solution to it. Fourth, I argue that the existence of NCC enjoys empirical support. I argue in particular that states associated with early stages of visual perceptual processing have NCC. (shrink)

To what extent is the external world the way that it appears to us in perceptual experience? This perennial question in philosophy is no doubt ambiguous in many ways. For example, it might be taken as equivalent to the question of whether or not the external world is the way that it appears to be? This is a question about the epistemology of perception: Are our perceptual experiences by and large veridical representations of the external world? Alternatively, the question might (...) be taken as asking whether or not the external world is like its ways of appearing to us, where the expression “ways of appearing” is intended to pick out aspects of our perceptual experiences themselves. This is a metaphysical version of the question of the relationship between appearance and reality: What is the relationship between the phenomenal features that characterize perceptual experience, on the one hand, and the mind-independent features of the external objects of perception, on the other? There are some philosophers who might resist distinguishing between these two questions. For them, “ways of appearing” in the phenomenal sense just are the ways that things appear to be (let’s call the latter the “intentional sense” of “ways of appearing”).1 That is, the phenomenal character of an experience is nothing over and above its representational content. Phenomenal properties are represented properties—the properties that an experience attributes to the external objects of perception. The question of whether or not phenomenal properties can be identified with the represented properties of an experience mirrors traditional questions in the philosophy of perception. If they can be identified with each other, then in veridical perception we might be said to “directly grasp” features of the external world through perception. The properties that are present to the mind are the very same properties that belong to the external objects of perception. Such a view affords.... (shrink)

Después de hacer un breve recuento del origen y de las confusiones del debate acerca del contenido no-conceptual de nuestra experiencia tanto en la tradición analítica como en las interpretaciones de la filosofía teórica de Kant, suscribo y complemento una de las objeciones de Oroño 2017 al no-conceptualismo de Heidemann 2016: que no debemos inferir a partir de la irreductibilidad de las intuiciones a conceptos que las intuiciones puedan representar objetos sin la actividad conceptual.

In the past twenty years, issues about the relationship between perception and thought have largely been framed in terms of the question of whether the contents of perception are nonconceptual. I argue that this debate has rested on an ambiguity in `nonconceptual content' and some false presuppositions about what is required for concept possession. Once these are cleared away, I argue that none of the arguments which have been advanced about nonconceptual content do much to threaten the natural view that (...) perception and thought are relations to the same kind of content.

A number of philosophers endorse, without argument, the view that there’s something it’s like consciously to think that p, which is distinct from what it’s like consciously to think that q. This thesis, if true, would have important consequences for philosophy of mind and cognitive science. In this paper I offer an argument for it, and attempt to induce examples of it in the reader. The argument claims it would be impossible introspectively to distinguish conscious thoughts with respect to their (...) content if there weren’t something it’s like to think them. This argument is defended against several objections. Then I use what I call “minimal pair” experiences—sentences read without and with understanding—to induce in the reader an experience of the kind I claim exists. Further objections are considered and rebutted. (shrink)

En su caracterización del contenido no conceptual, Christopher Peacocke realiza un esfuerzo constante por diferenciar el contenido no conceptual protoproposicional que propone del contenido de tipo conceptual. En este trabajo analizaré tales esfuerzos para concluir que resultan infructuosos, llevando al autor a lo que podría denominarse como una rotulación incorrecta del contenido protoproposicional como no conceptual. Para ello, reconstruiré la posición no conceptualista de Peacocke y señalaré, mediante los ejemplos que el mismo autor ofrece, la gran similitud que existe entre (...) ciertos contenidos y procesos paradigmáticamente conceptuales, y los ejemplos de contenidos y procesos que el autor considera como protoproposicionales y presuntamente no conceptuales.

A satisfactory solution to the problem of consciousness would take the form of a simple yet fully general model that specifies the precise conditions under which any given state of consciousness occurs. Science has uncovered numerous correlations between consciousness and neural activity, but it has not yet come anywhere close to this. We are still looking for the Newtonian laws of consciousness. -/- One of the main difficulties with consciousness is that we lack a language in which to formulate illuminating (...) generalizations about it. Philosophers and scientists talk about "what it’s like", sensations, feelings, and perceptual states such as seeing and hearing. This language does not allow a precise articulation of the internal structures of conscious states and their inter-relations. It is inadequate to capture relations of the kind we are looking for between conscious states and physical states. -/- In this thesis I refine and defend a theory of consciousness which promises to solve this regimentation problem: the representational theory of consciousness. I argue that the representational theory can solve the regimentation problem and smooth out other important obstacles to a fruitful study of consciousness. I also make a case for the theory independently of its payoffs, and I discuss the leading opposing theories at some length. (shrink)

This article is a summary of two chapters of a book published in French in 1997, entitled Comment L'esprit vient aux Bêtes, Paris, Gallimard. The core idea is that the crucial distinction between internal and external states, often used uncritically by theorists of intentionality, needs to be made on a non-circular basis. The proposal is that objectivity - the capacity to reidentify individuals as the same across places and times depends on the capacity to extract spatial crossmodal invariants, which in (...) turn presupposes a capacity to (re)calibrate perceptual inputs across modalities in a principled way.

The notion of a "mental representation" is, arguably, in the first instance a theoretical construct of cognitive science. As such, it is a basic concept of the Computational Theory of Mind, according to which cognitive states and processes are constituted by the occurrence, transformation and storage (in the mind/brain) of information-bearing structures (representations) of one kind or another.

Among the exciting prospects raised by advocates of predictive processing [PP] is the offer of a systematic description of our neural activity suitable for drawing explanatory bridges to the structure of conscious experience. Yet the gulf to cross seems wide. For, as critics of PP have argued, our visual experience certainly doesn’t seem probabilistic.While Clark proposes a means to make PP compatible with the experience of a determinate world, I argue that we should not rush to do so. Two notions (...) of determinacy are conflated in the claim that perception is determinate: ‘univocality’ and ‘full detail’. The former, as Clark argues, is only to be expected in any PP agent that models its world for the purpose of acting on it. But as Husserl argued, and as perceptual psychology has borne out, we significantly overestimate the degree of detail with which we perceive a univocal world.This second form of indeterminacy is due not to the probabilistic nature of PP’s model, but rather to its hierarchical structure, with increasingly coarse-grained representations as we move further from the sensory periphery. A PP system may, or may not, deliver a univocal hypothesis at each of these levels. An action-oriented PP system would only be expected to do so only at the level needed for successful action guidance. A naïve reporter’s overestimation of the degree of determinate detail in their visual experience can thereby be accounted for with a more gradual version of the ‘refrigerator light’ effect: we experience determinate details just to the degree that they’re needed – immediately as they’re needed.
