How should physical entities be characterized? Physicalists, who have most to do with the notion, usually characterize the physical by reference to two components: 1. The physical entities are the entities treated by fundamental physics with the proviso that 2. Physical entities are not fundamentally mental (that is, do not individually possess or bestow mentality) Here I explore the extent to which the appeals to fundamental physics and to the NFM (“no fundamental mentality”) constraint are appropriate for characterizing the physical, (...) especially for purposes of formulating physicalism. Ultimately, I motivate and defend a version of an account incorporating both components: The physics-based NFM account: An entity existing at a world w is physical iff (i) it is treated, approximately accurately, by current or future (in the limit of inquiry, ideal) versions of fundamental physics at w, and (ii) it is not fundamentally mental (that is, does not individually either possess or bestow mentality).

One of the promising approaches to the problem of perceptual consciousness has been the representational theory, or representationalism. The idea is to reduce the phenomenal character of conscious perceptual experiences to the representational content of those experiences. Most representationalists appeal specifically to non-conceptual content in reducing phenomenal character to representational content. In this paper, I discuss a series of issues involved in this representationalist appeal to non-conceptual content. The overall argument is the following. On the face of it, conscious perceptual (...) experience appears to be experience of a structured world, hence to be at least partly conceptual. To validate the appeal to non-conceptual content, the representationalist must therefore hold that the content of experience is partly conceptual and partly non-conceptual. But how can the conceptual and the non-conceptual combine to form a single content? The only way to make sense of this notion, I argue, leads to a surprising consequence, namely, that the representational approach to perceptual consciousness is a disguised form of functionalism.

Qualia inversion thought experiments are ubiquitous in contemporary philosophy of mind. The most popular kind is one or another variant of Locke's hypothetical case of.

Are there different constraints on theories of conscious experience as against theories of conscious propositional thought? Is what is problematic or puzzling about each of these phenomena of the same, or of different, types? And to what extent is it plausible to think that either or both conscious experience and conscious thought involve some sort of selfreference? In pursuing these questions I shall also explore the prospects for a defensible form of eliminativism concerning conscious thinking, one that would leave the (...) reality of conscious experience untouched. In the end, I shall argue that while there might be no such thing as conscious judging or conscious wanting, there is (or may well be) such a thing as conscious generic thinking. (shrink)

It is often assumed thatconsciousness and intentionality are twomutually independent aspects of mental life.When the assumption is denounced, it usuallygives way to the claim that consciousness issomehow dependent upon intentionality. Thepossibility that intentionality may bedependent upon consciousness is rarelyentertained. Recently, however, John Searle andColin McGinn have argued for just suchdependence. In this paper, I reconstruct andevaluate their argumentation. I am in sympathyboth with their view and with the lines ofargument they employ in its defense. UnlikeSearle and McGinn, however, I am (...) quite attachedto a naturalist approach to intentionality. Itwill turn out to be somewhat difficult toreconcile naturalism with the notion thatintentionality is dependent upon consciousness,although, perhaps surprisingly, I will arguethat McGinn's case for such dependence iscompatible with naturalism.

Recently, Peter Carruthers has advanced the debate over first-order representationalist theories and higher-order representationalist theories of consciousness by offering two innovative arguments in support of dispositionalist HORs. In this article, I offer a limited defense of actualist FORs by showing that Carruthers' two arguments either beg the question against such accounts, equivocate on important concepts, or rest on suspect claims about our abilities to attribute phenomenal consciousness to animals. In addition, I argue that dispositionalist HORs face an apparent counterexample, one (...) which Carruthers does not consider. (shrink)

The Elephant and the Blind is a book about why we need a new culture of consciousness, and how to get it. A culture of consciousness (or Bewusstseinskultur) is a culture that values and cultivates the mental states of its members in an ethical and evidence-based way.

I consider the nature of research, both as a mode of learning about the world, with the focus on the object of research, and as a role for staff and students in the higher education sector, with the focus on the practice to be learned, on the pedagogy of research. The domain of research and researchers has, like other domains of higher education and like education more widely, has received a good deal of policy attention. In the UK, there has (...) been the growing “impact agenda”, an attempt to measure the worth of research projects by the social, and especially economic, benefits they would bring about. Critics of this agenda need, in order to maintain their stance, to appreciate the metaphysical importance of Kant’s noumenon, supplemented by Priest’s “torn boundary” thesis, for the object of research. The new Researcher Development Framework, being launched in 2011, will supplant the 2001 “Joint Skills Statement”. Criticisms that this “skills agenda” is too generic to be useful and not sufficiently academic in character to be appropriate for the pedagogy of research are wide of the mark. Examination of the various senses of the “tacit dimension” in Polanyi variously inform discussion of these criticisms. (shrink)

Emotion is conceptualised as an emergent, dynamic process based on an individual's subjective appraisal of significant events. It is argued that theoretical models of emotion need to propose an architecture that reflects the essential nature and functions of emotion as a psychobiological and cultural adaptation mechanism. One proposal for such a model and its underlying dynamic architecture, the component process model, is briefly sketched and compared with some of its major competitors. Recent empirical evidence in support of the model is (...) reviewed. Special emphasis is given to the dynamic aspect of emotion processes, in particular the sequence of appraisal checks and the synchronisation of response systems, as well as the capacity of the model to predict individual differences in emotional responding.

Susan Hurley has attacked the ''Duplication Assumption'', the assumption thatcreatures with exactly the same internal states could function exactly alike inenvironments that are systematically distorted. She argues that the dynamicalinterdependence of action and perception is highly problematic for the DuplicationAssumption when it involves spatial states and capacities, whereas no such problemsarise when it involves color states and capacities. I will try to establish that theDuplication Assumption makes even less sense for lightness than for some ofthe spatial cases. This is due (...) not only to motor factors, but to the basic physicalasymmetry between black and white. I then argue that the case can be extendedfrom lightness perception to hue perception. Overall, the aims of this paper are:(1) to extend Susan Hurley''s critique of the Duplication Assumption; (2) to argueagainst highly constrained versions of Inverted Spectrum arguments; (3) to proposea broader conception of the vehicle for color perception.

Consider the much-discussed case of the distracted driver, who is alleged to successfully navigate his car for miles despite being completely oblivious to his visual states. Perhaps he is deeply engrossed in the music playing over the radio or in philosophical reflection, and as a result he goes about unaware of the scene unfolding before him on the road. That the distracted driver has visual experiences of which he is not aware is a possibility that first-order representationalists happily accept, but (...) higher-order representationalists steadfastly deny. HOR claims that perceptual states become conscious only as the object of higher-order states; perceptual states are not intrinsically conscious. According to HOR, since the driver is supposed to be completely distracted by other cognitive tasks, he cannot form higher-order representations of his visual states, with the result that those states are disqualified as experiences.1 HOR theories have come in two flavors, those that claim that the relevant higher-order representations are thought-like and those that that rely on an inner perception-like mechanism that is directed toward one.

Contrary to certain rumours, the mind-body problem is alive and well. So argues Joseph Levine in Purple Haze: The Puzzle of Consciousness . The main argument is simple enough. Considerations of causal efficacy require us to accept that subjective experiential, or 'phenomenal', properties are realized in basic non-mental, probably physical properties. But no amount of knowledge of those physical properties will allow us conclusively to deduce facts about the existence and nature of phenomenal properties. This failure of deducibility constitutes an (...) explanatory problem - an explanatory gap - but does not imply the existence of immaterial mental properties. Levine introduced this notion of the explanatory gap almost two decades ago. Purple Haze allows Levine to situate the explanatory gap in a broader philosophical context. He engages with those who hold that the explanatory gap is best understood as implying anti-materialist metaphysical conclusions. But he also seeks to distance himself from contemporary naturalistic philosophical theorizing about consciousness by arguing that reductive and eliminative theories of consciousness all fail. Levine's work is best seen as an attempt to firmly establish a definite status for the mind-body problem, i.e. that the mind-body problem is a real, substantive epistemological problem but emphatically not a metaphysical one. Because Levine's work is tightly focused upon contemporary Anglophone analytic philosophy of mind, there is little discussion of the broader conceptual background to the mind-body problem. My aim here is to place Levine's work in a broader conceptual context. In particular, I focus on the relationship between consciousness and intentionality in the belief that doing so will allow us better to understand and evaluate Levine's arguments and their place in contemporary theorizing about mentality and consciousness.

Is there an explanatory gap between raw feels and raw material? Some philosophers argue, and many other people believe, that scientific explanations of conscious experience cannot be as satisfying as typical scientific explanations elsewhere, even in our wildest dreams. The underlying philosophical claims are.

_Consciousness, Color, and Content_ is a significant contribution to our understanding of consciousness, among other things. I have learned a lot from it, as well as Tye.

The problem of consciousness is one of the most important problems both in cognitive science and in philosophy. There are different philosophers and different scientists who define consciousness and explain it differently. In philosophy, ‘consciousness’ does not have a definition in terms of genus and differentia or necessary and sufficient conditions. In this paper, I shall explore the very idea of machine consciousness. The machine consciousness has offered causal explanation to the ‘how’ and ‘what’ of consciousness, but they fail to (...) explain the ‘why’ of consciousness. Their explanation is based on the ground that consciousness is causally dependent on the material universe and that of all conscious phenomena can be explained by mapping the physical universe. In this regard, consciousness is basically a physical phenomenon and can be mechanically explained following the naturalistic methods of science. In other words, the mechanistic assumption is that consciousness and mind have an artificial origin and therefore have to be understood only within a mechanistic framework available in the sciences. If this is so, then this epistemological theory of consciousness is essentially committed to scientific world view that cannot avoid metaphysical implication of consciousness. At the same time, neo-Advaitins have maintained that the evolution of nature leads to the manifestation of human consciousness only because consciousness is already implicit in the material nature. Thus, the existence of consciousness in this physical world far exceeds the methods of science and needs a non-mechanical metaphysical explanation. (shrink)

There are a number of dispositionalist solutions to the free will problem based on freedom consisting in the agent's exercise of a power. But if a subject a is free when they exercise their power P, there is an objection to be overcome from the possibility of power implantation. A brainwasher, rather than directly manipulating a subject's movements, can instead implant in them a desire, to be understood as a disposition to act, and allow the subject to exercise such a (...) power. It seems that, according to the dispositionalist theory of freedom, such an agent would still count as acting freely. There is a strong non-consent intuition that a is not free in such a case because they did not consent to having the power P—the desire in question. Filling out this intuition is not straightforward. But it can be done in terms of the exercise of P being regulated by higher-order powers of self-reflection. Such regulation is what allows an agent to either take ownership of a power or to reject it. (shrink)

Inverted sensation arguments such as the inverted spectrum thought experiment are often criticized for relying on an unconstrained notion of 'qualia'. In reply to this criticism, 'qualia-free' arguments for inversion have been proposed, in which only physical changes happen: inversions in the world, such as the replacement of surface colors by their complements, and a rewiring of peripheral input cables to more central areas in the nervous system. I show why such constrained inversion arguments won't work. The first problem is (...) that the world lacks the symmetry required to invert physical properties in the way required. The second problem concerns 'rewiring'. Empirical evidence indicates that the rewirings are either impossible, or would not result in an inversion of sensation. I propose the deeper reason for the failure of constrained inversion arguments lies in the fact that sensations are not properties of brain states, but spread into the world and the body. (shrink)

The very idea of unconscious emotion has been thought puzzling. But in recent debate about emotions, comparatively little attention has been given explicitly to the question. I survey a number of recent attempts by philosophers to resolve the puzzle and provide some preliminary remarks about their viability. I identify and discuss three families of responses: unconscious emotions involve conscious feelings, unconscious emotions involve no feelings at all, and unconscious emotions involve unconscious feelings. The discussion is exploratory rather than decisive for (...) three reasons. First, the aim is to provide a framework for the debate, and identify a number of key issues for further research. Second, a number of the positions depend for their plausibility upon theoretical commitments that can be made clear, but cannot be evaluated in detail, in a survey article. Third, I believe no fully satisfactory, comprehensive solution has yet been developed. (shrink)

RÉSUMÉ: Les discussions philosophiques actuelles sur le problème de la conscience [consciousness] se concentrent sur la question des qualia, ou qualités sensorielles. Mais les auteurs traditionnels au sujet de la conscience—tels que Kant et William James—s'intéressaient davantage à un autre aspect de l'expérience consciente, à savoir le fait que lorsqu'on est conscient [conscious], on est en même temps, et de façon permanente, conscient de soi-même [aware of oneself] comme sujet de l'expérience. Cet article explore trois modèles représentationnels du phénomène de (...) la conscience permanente de soi [permanent self-awareness]. Chacun d'eux se révèle inadéquat pour une raison ou pour une autre. Ce que la discussion fait ainsi ressortir, c'est le genre d'exigences auxquels devrait satisfaire une bonne théorie de la conscience permanente de soi. (shrink)

Sydney Shoemaker thinks the ‘most revealing characterization of physicalism’ is in terms of realization . He offers a meticulously worked out account of physical realization and goes on to apply it to a range of major topics: mental causation, personal identity, emergence, three-dimensional versus four-dimensional accounts of temporal persistence, qualia. 1 He also discusses constitution by micro-entities, functional properties, causation by ‘second-order’ properties, ‘phony’ and ‘genuine’ properties, and whether mental properties strongly supervene on physical ones. Several parts of the book (...) are devoted to criticizing Jaegwon Kim's views, especially in his Physicalism, or Something Near Enough .I shall concentrate on three main issues: whether, as Shoemaker claims, his official view of physical realization provides for a ‘constitutive link’ between the realizer and what it realizes; whether his account is a ‘revealing’ characterization of physicalism; and his discussions of transposed and ‘alien’ qualia. Let me remark that numerous potential objections are treated with sophistication and subtlety. At several places, this makes for difficult reading . It also means I shall usually be simplifying the views I attribute to him. (shrink)

Kim maintains that a physicalist has only two genuine options, eliminativism and reductionism. But physicalists can reject both by using the Strict Implication thesis (SI). Discussing his arguments will help to show what useful work SI can do.(1) His discussion of anomalous monism depends on an unexamined assumption to the effect that SI is false.

This is a big-picture book, 2 written with a breadth of focus which I find admirable. It exhibits what's come to be known as the ‘intersubdiscplinary’ approach to philosophy, which is not restricted by traditional boundaries within the discipline but rather proceeds with an eye to all sorts of areas of philosophy where relevant arguments, results, analogies and strategies might be lurking. I approve of this way of doing philosophy; it seems to me that all too often that wheels are (...) reinvented, or crucial points missed, because of a lack of this sort of intersubdisciplinarity.To help guide us through such a broad landscape, this book needed to be well-signposted and clearly written, and it is. It cannot be denied, however, that the ambitious scale of The Nature of Normativity won't be to every taste. For one thing, not everyone likes big pictures. For another, this is a deep, dense and in many ways difficult book, which can only really be appreciated by sitting down with it for hours on end. It will not repay the casual skim-reader, nor is it likely to appeal to those who prefer dipping into philosophy books over reading them wholesale.The book is also long . The view under construction has a great many interlocking elements, including non-reductive normative naturalism, normative realism, a priorist intuitionism, normative internalism, the normativity of intentionality, conceptual-role semantics, contextualism, possible-worlds semantics, and certain ideas about ‘planning’ derived from the recent work of Allan Gibbard. It will be a tough read for specialists who do not share Wedgwood's familiarity with a wide range of subdisciplines, who will either have to content themselves with a superficial reading of many passages or else hunt down the necessary background material to ….

This thesis has, as its primary target, the neo-cartesianism, or property dualism of certain philosophers of mind: David Chalmers, Tim Bayne, and others. All begin with a pre-theoretic commitment to the view that all perceptual states are conscious. They define consciousness by saying that it is synonymous with having ‘qualia’ – a term directed at phenomenal properties which defy reduction to physical states. The thesis argues that this position is challenged by certain neurological conditions, - blindsight, visual form agnosia etc- (...) which we can generalise as ‘dissociations’: conditions in which functions are separated from awareness. The thesis holds that these are examples of unconscious perception, which present the case for a different pre-theoretic position, and a redefinition of concepts used in the vicinity. Insofar as the neo-cartesians recognise the empirical, their inclination to reject the dissociations is challenged with new cases and paradigms which have emerged in recent years. It is contended that the dissociations disrupt Chalmers’ coherence between the phenomenal and the psychological, Bayne’s commitment to the Unity of Consciousness, and Phillips’ campaign against unconscious perception. In addition, synaesthesia is advanced as a problem case for Bayne’s unity contention. I argue that the dissociations are not easily dismissed, and present a real challenge for neo-cartesianism. In exploring this challenge, the thesis contributes to the case for a different philosophy of mind – a Higher Order Thought approach. The notion of unconscious perception – it is contended - much more easily finds an accommodation in HOT theories, so this thesis contributes to existing arguments for that position. HOT theories also have an advantage in being receptive to reduction, in giving a developmental account of consciousness, and in being more open to the accommodation of empirical discoveries. In each respect, there is an advantage over the respective positions taken by Chalmers and Bayne. (shrink)

My aim in this paper is chiefly one of conceptual clarification, linking with issues arising within certain current debates. I propose a typology to underpin the various applications of the “tacit” and the “non-discursive” for describing our state of knowledge as regards respectively both the practice and the object of research. The tacit/explicit dichotomy is a different one from the non-discursive/discursive one. This is key if we are to understand how the process of learning to research, as well as learning (...) most practices, occurs. The UK national research training agenda is crystallized in the 2001 document “Skills training requirements for research students: joint statement by the research councils/AHRB”. This is an attempt to lay out in generic terms the categories of skills that researchers should develop during their course of study. It is meant to be applicable to all subjects and therefore to educational and other social science and humanities newer researchers. Critics, such as Stephen Rowland, of the national policy point out that aiming to teach skills conceived generically out of context is a flawed approach. This is true but misses the point that codifications of practice inevitably fail to capture the practice in its entirety. This is for two reasons. The first is a function of the informal and non-discursive components of any practice, the particular actions of more experienced researchers which may need no discursive explanation for the novice to be able to pick them up in context, “on the job”. The point is not that this is essentially tacit knowledge, learnt unwittingly. Rather, it may or may not be explicitly recognized and considered by the learner, even in the “hot action” workplace scenario, but it is effectively non-discursive. Much of what we learn will turn into tacit knowing through the more straightforward process expounded by Michael Polanyi, in that it would become “second nature”, so we would not need to be explaining it to ourselves anymore to achieve phronesis. Polanyi allows us to see that much of what seems mysterious in what people do, because people are not inclined to say much about it, is not at the same time mystical. Immanuel Kant's concept of the noumenon, or noumenal world, by contrast is what has been always beyond our powers of cognition, a statement of our finitude, if you like, although we may make gradual incursion into it as we find out more about the world. The noumenon, tacit because ineffable, is therefore a way to conceive the nature of research generally from the point of view of its object, what it is trying to uncover. Does this framework apply to biographical research? 1) One answer says no. If the research outcome is the discursive telling of a biographical narrative of a particular person then, arguably, it is the latest arrangement of concepts that are already known to us, a life story which makes sense because familiar. This view plays into the hands of those, such as Galen Strawson, who are sceptical of the claims of narrative to be articulating what has actually happened to a person and what they are like as a person. This challenge is compounded when we introduce Robert Kirk’s “raw feeling” thesis, which claims that there is an important aspect in our experience which is beyond language and this aspect is all the richer: language can only fumble towards capturing it. A life story is just a story in this context, only able to brush the surface of the life proper. 2) But this gives us a clue to how we may answer yes to the question. Research is not just the uncovering of what is previously covered up but is the process of making sense of it. Even the PhD thesis in Chemistry must embody a narrative. The turning into sense of what is at first indeterminate is a function of narrative and is also a version of Kant’s epistemology insofar as he describes how we make cognitive judgements about the phenomenon at issue. Although this account of the biographical research process does push us towards turning people into ideal types rather than particulars, it does also allow us permanently to posit that there may be something as yet beyond the articulated phenomenon, something sitting tacitly in the noumenal world, perhaps the self and its possibilities, which cannot be fully captured by the narrative articulation.

I am lucky to have two such penetrating commentators as Robert Kirk and Andrew Melnyk. It is also fortunate that they come at me from different directions, and so cover different aspects of my book. Robert Kirk has doubts about the overall structure of my enterprise, and in particular about my central commitment to a distinctive species of phenomenal concepts. Andrew Melnyk, by contrast, offers no objections to my general brand of materialism. Instead he focuses specifically on my discussion of (...) the anti-materialist 'intuition of distinctness', raising questions about my attempt to explain this intuition away, and offering alternative suggestions of his own.

I argue that Carruthers' arguments that animals are unable to have conscious experience relies on a human-centered view of consciousness. Once we abandon those characteristics of consciousness that are typically human, such as the ability to reason about one's conscious experience, it becomes clear that animals may have conscious experience, although such experience may not be available as the subject of thought. Consideration of evidence from human conscious experience, child development, and evolution supports this suggestion.

In this paper I shall defend a projectivist view of sensory experience. The case I shall focus on is that of color experience. Projectivism has recently been criticized by some authors who claim that it is unintelligible, or at least implausible, and that it makes a severe category mistake. I shall argue that despite some prima facie impressions of implausibility, projectivism can be made intelligible, and plausible, if its details are spelled out in a reasonable way. In addition, projectivism is (...) ubiquitous in human psychology, and certain cases of projection are reasonably viewed as making a category mistake. Viewed from this perspective, sensory projection is just one instance of projectivism, brought about by low-level perceptual processing. Whether sensory projection is one that makes a category mistake is not obvious. However, even if it does, this is perfectly compatible with the evolutionary advantage of sensation and perception.
