How can phenomenal consciousness exist as an integral part of a physical universe? How can the technicolour phenomenology of our inner lives be created out of the complex neural activities of our brains? Many have despaired of finding answers to these questions; and many have claimed that human consciousness is inherently mysterious. Peter Carruthers argues, on the contrary, that the subjective feel of our experience is fully explicable in naturalistic terms. Drawing on a variety of interdisciplinary resources, (...) he develops and defends a novel account in terms of higher-order thought. He shows that this can explain away some of the more extravagant claims made about phenomenal consciousness, while substantively explaining the key subjectivity of our experience. Written with characteristic clarity and directness, and surveying a wide range of extant theories, this book is essential reading for all those within philosophy and psychology interested in the problem of consciousness.

How can one investigate phenomenal consciousness? As in other areas of science, the investigation of consciousness aims for a more precise knowledge of its phenomena, and the discovery of general truths about their nature. This requires the development of appropriate first-person, second-person, and third-person methods. This book introduces some of the creative ways in which these methods can be applied to different purposes, e.g. to understand the relation of consciousness to brain, to examining or changing (...) class='Hi'>consciousness as such, and to the way consciousness is influenced by social, clinical and therapeutic contexts. To clarify the strengths and weaknesses of different methods and to demonstrate the interplay of methodology and epistemology, the book also suggests a number of "maps" of the consciousness studies terrain that places different approaches to the study of consciousness into a broader, interdisciplinary context.

Phenomenal consciousness poses a puzzle for philosophy of science. This arises from two facts: It is common for philosophers (and some scientists) to take its existence to be phenomenologically obvious and yet modern science arguably has little (if anything) to say about it. And, this despite 20 years of work targeting the phenomenon in what I will refer to as the new science of consciousness. How has such a supposedly evident part of our world remained beyond our (...) scientific understanding? One possibility is that there is no such phenomenon. This possibility, however, is undercut by the claim that phenomenal consciousness is phenomenologically obvious. In this paper I argue that this claim is mistaken. Distinguishing between the qualities we are phenomenologically aware of and the classification of those qualities as being mental (as qualia), I present both empirical evidence and theoretical reasons to deny that the latter is phenomenologically obvious.

The objective of this paper is to defend the non-reductive thesis of phenomenal consciousness. This paper will give an overview of the arguments for the non-reductive explanation of phenomenal consciousness and justify why the reductionist approach is implausible in the context of explaining phenomenal subjective experience. The debate between reductionist and non-reductionist on the project of demystifying and mystifying phenomenal consciousness is driven by two fundamental assumptions-1) Reductive-Naturalistic Objectivism, 2) Phenomenal Realism. There (...) are several arguments for the irreducibility of phenomenal consciousness; this paper will focus on the inverted spectrum argument, knowledge argument, and the conceivability argument.

(for online upload) The readings in Investigating Phenomenal Consciousness (2000) were developed from an International Symposium on Methodologies for the Study of Consciousness: A new Synthesis,” that I organised in April, 1996, funded and hosted by the Fetzer Institute, Wisconsin, USA, with the aim of fostering the development of first-person methods that could be used in conjunction with already well-developed third-person methods for investigating phenomenal consciousness. In this Introduction, we briefly survey the state of the (...) art at that time, the reasons for a resurgence of interest in consciousness, the available methodologies, the reasons for increasing dissatisfaction with the adequacy of reductive third-person methods, various difficulties facing the development of rigorous first-person methods, and various creative approaches to solving these difficulties. Suggestions are also made about how to heal the fragmentation in consciousness studies, by placing different approaches to the study of consciousness into a broader context, establishing their domain of applicability and providing some bases for synthesis.

The paper discusses some recent suggestions offered by the so-called sensorimotor (or enactivist) theorists as to the problem of the explanatory gap, that is, the alleged impossibility of accounting for phenomenal consciousness in any scientific theory. We argue in the paper that, although some enactivist theorists’ suggestions appear fresh and eye-opening, the claim that the explanatory gap is (dis)solved is much overstated.

In this paper, I argue against the claim recently defended by Josh Weisberg that a certain version of the self-representational approach to phenomenal consciousness cannot avoid a set of problems that have plagued higher-order approaches. These problems arise specifically for theories that allow for higher-order misrepresentation or—in the domain of self-representational theories—self-misrepresentation. In response to Weisberg, I articulate a self-representational theory of phenomenal consciousness according to which it is contingently impossible for self-representations tokened in the context (...) of a conscious mental state to misrepresent their objects. This contingent infallibility allows the theory to both acknowledge the (logical) possibility of self-misrepresentation and avoid the problems of self-misrepresentation. Expanding further on Weisberg’s work, I consider and reveal the shortcomings of three other self-representational models—put forward by Kreigel, Van Gulick, and Gennaro—in order to show that each indicates the need for this sort of infallibility. I then argue that contingent infallibility is in principle acceptable on naturalistic grounds only if we attribute (1) a neo-Fregean kind of directly referring, indexical content to self-representational mental states and (2) a certain ontological structure to the complex conscious mental states of which these indexical self-representations are a part. In these sections I draw on ideas from the work of Perry and Kaplan to articulate the context-dependent semantic structure of inner-representational states. (shrink)

Delirium has conventionally been considered a disorder of consciousness, but this remains a relatively unexamined precept. First, a review of the role of consciousness disruption in delirium is revised from an historical and diagnostic perspective. Second, consciousness measurement in routine assessment of delirium is considered. Conscious levels, comprising alertness and arousal, are most commonly used but are not representative of the multidimensionality of consciousness. Third, a justification for the exploration of phenomenal consciousness is presented. (...) Three candidate dimensions of phenomenal consciousness are identified as the pre-reflective state, phenomenal experience, and reflective thought. Finally, the clinical implications of a deeper understanding of delirium through measurement of phenomenal consciousness is considered. (shrink)

Are corporations and other complex groups ever morally responsible in ways that do not reduce to the moral responsibility of their members? Christian List, Phillip Pettit, Kendy Hess, and David Copp have recently defended the idea that they can be. For them, complex groups (sometimes called collectives) can be irreducibly morally responsible because they satisfy the conditions for morally responsible agency; and this view is made more plausible by the claim (made by Theiner) that collectives can have minds. In this (...) paper I give a new argument against the idea that collectives can be irreducibly morally responsible in the ways that individuals can be. Drawing on recent work in the philosophy of mind (what Uriah Kriegel calls "the phenomenal intentionality research program") and moral theory (David Shoemaker's tripartite theory of moral responsibility), I argue that for something to have a mind, it must be phenomenally conscious, and that the fact that collectives lack phenomenal consciousness implies that they are incapable of accountability, an important form of moral responsibility.

I draw attention to an ambiguity of the expression ‘phenomenal consciousness’ that is an avoidable yet persistent source of conceptual confusion among consciousness scientists. The ambiguity is between what I call phenomenality and what I call conscious states, where the former denotes an abstract property and the latter denotes a phenomenon or class of its instances. Since sentences featuring these two terms have different semantic properties, it is possible to equivocate over the term ‘consciousness’. It is (...) also possible to fail to distinguish between statements that are true about conscious states in virtue of their phenomenality, and statements that are true in virtue of other properties of conscious states. I review empirically informed arguments by scientists Bernard Balleine and Anthony Dickinson, Stevan Harnad, and Jeffrey Alan Gray, arguing that each of them makes errors based on the ambiguity. I conclude with some tentative suggestions for avoiding further confusion about the ambiguity. (shrink)

I argue that it is at least open to a proponent of type materialism for phenomenal consciousness to accept Hill’s representational theory of experiential awareness of perceptual qualia.

Key Terms: Phenomenal consciousness, access consciousness, qualitative character, subjective character, intransitive self-consciousness, disposition, categorical basis, subliminal perception, blindsight.

I propose and defend the Allocentric-Egocentric Interface Theory of Con- sciousness. Mental processes form a hierarchy of mental representations with maxi- mally egocentric (self-centered) representations at the bottom and maximally allocentric (other-centered) representations at the top. Phenomenally conscious states are states that are relatively intermediate in this hierarchy. More speci.

Phenomenal consciousness can be conceptualized innocently enough that its existence should be accepted even by philosophers who wish to avoid dubious epistemic and metaphysical commitments such as dualism, infallibilism, privacy, inexplicability, or intrinsic simplicity. Definition by example allows us this innocence. Positive examples include sensory experiences, imagery experiences, vivid emotions, and dreams. Negative examples include growth hormone release, dispositional knowledge, standing intentions, and sensory reactivity to masked visual displays. Phenomenal consciousness is the most folk-psychologically obvious thing (...) or feature that the positive examples possess and that the negative examples lack, and which preserves our ability to wonder, at least temporarily, about antecedently unclear issues such as consciousness without attention and consciousness in simpler animals. As long as this concept is not empty, or broken, or a hodgepodge, we can be phenomenal realists without committing to dubious philosophical positions. (shrink)

Two debates loom large in current discussions on phenomenal consciousness. One debate concerns the relation between phenomenal character and representational content. Representationalism affirms, whereas “content separatism” denies, that phenomenal character is exhausted by representational content. Another debate concerns the relation between phenomenal consciousness and cognitive access. “Access separatism” affirms, whereas, e.g., the global workspace model denies, that there are phenomenally conscious states that are not cognitively accessed. I will argue that the two separatist views (...) are related. Access separatism supports content separatism by undermining the most prominent sort of arguments in favor of representationalism, namely ones that appeal to the phenomenology of perceptual experiences.

Commentary on Charles Siewert's The Significance of Consciousness (Princeton, 1998). I discuss three issues about the relation of phenomenal consciousness, in the sense Siewert isolates, to intentionality. The first is whether, contrary to Siewert, phenomenal consciousness requires higher-order representation. The second is whether intentional features of conscious states are identical with phenomenal features, as Siewert argues, or merely conceptually supervene on them, with special attention to cross modal representations of objects in space. The third (...) is whether phenomenal features are identical with what we can have first person access to, with special attention to features of thoughts that are individuated by reference to the self and the present time.

The terminology surrounding the dispute between higher-order and first-order theories of consciousness is piled so high that it sometimes obscures the view. When the debris is cleared away, there is a real prospect.

This paper examines the possibility of finding evidence that phenomenal consciousness is independent of access. The suggestion reviewed is that we should look for isomorphisms between phenomenal and neural activation spaces. It is argued that the fact that phenomenal spaces are mapped via verbal report is no problem for this methodology. The fact that activation and phenomenal space are mapped via different means does not mean that they cannot be identified. The paper finishes by examining (...) how data addressing this theoretical question could be obtained. (shrink)

Dreaming can be explained as the product of an interaction among memory processes, elaborative processes, and phenomenal awareness. A feedback circuit is activated by this interaction according to the associative links and the requirements of the dream scene. Recently, it has been hypothesized that a partial similarity exists between dreaming and mind wandering and that these two processes may involve the same neural default network. This commentary discusses the differences and similarities between phenomenal consciousness during dreaming and (...) phenomenal consciousness during mind wandering from the perspective of the “continuity” of engagement of cognitive systems. The greatest difference consists in the lack of reality testing during dreaming. Dream imagery is hallucinatory by nature. Consequently, the simulated world in dreams makes dream imagery more akin to perception. In contrast, the imagery of mind wandering is more similar to imagination. The level of meta-awareness is preserved more frequ... (shrink)

William S. Robinson has for many years written insightfully about the mind-body problem. In Understanding Phenomenal Consciousness he focuses on sensory experience and perception qualities such as colours, sounds and odours to present a dualistic view of the mind, called Qualitative Event Realism, that goes against the dominant materialist views. This theory is relevant to the development of a science of consciousness which is now being pursued not only by philosophers but by researchers in psychology and the (...) brain sciences. This provocative book will interest students and professionals who work in the philosophy of mind and will also have cross-disciplinary appeal in cognitive psychology and the brain sciences.

Block tries to show that the results of the Sperling experiment lend support to the view that phenomenology outstrips cognitive accessibility. I argue that Block fails to make a compelling case for this general claim on the basis of the Sperling data.

The role of emergence in the creation of consciousness has been debated for over a century, but it remains unresolved. In particular there is controversy over the claim that a “strong” or radical form of emergence is required to explain phenomenal consciousness. In this paper we use some ideas of complex system theory to trace the emergent features of life and then of complex brains through three progressive stages or levels: Level 1 (life), Level 2 (nervous systems), (...) and Level 3 (special neurobiological features), each representing increasing biological and neurobiological complexity and ultimately leading to the emergence of phenomenal consciousness, all in physical systems. Along the way we show that consciousness fits the criteria of an emergent property—albeit one with extreme complexity. The formulation Life + Special neurobiological features → Phenomenal consciousness expresses these relationships. Then we consider the implications of our findings for some of the philosophical conundrums entailed by the apparent “explanatory gap” between the brain and phenomenal consciousness. We conclude that consciousness stems from the personal life of an organism with the addition of a complex nervous system that is ideally suited to maximize emergent neurobiological features and that it is an example of standard (“weak”) emergence without a scientific explanatory gap. An “experiential” or epistemic gap remains, although this is ontologically untroubling. (shrink)

How can the fine-grained phenomenology of conscious experience arise from neural processes in the brain? How does a set of action potentials (nerve impulses) become like the feeling of pain in one's experience? Contemporary neuroscience is teaching us that our mental states correlate with neural processes in the brain. However, although we know that experience arises from a physical basis, we don't have a good explanation of why and how it so arises. The problem of how physical processes give rise (...) to experience is called the 'hard problem' of consciousness and it is the contemporary manifestation of the mind-body problem. This book explains the key concepts that surround the issue as well as the nature of the hard problem and the several approaches to it. It gives a comprehensive treatment of the phenomenon incorporating its main metaphysical and epistemic aspects, as well as recent empirical findings, such as the phenomenon of blindsight, change blindness, visual-form agnosia and optic ataraxia, mirror recognition in other primates, split-brain cases and synaesthesia.

The main aim of this paper is to show that we can extract an elaborate account of phe- nomenal consciousness from Leibniz’s (1646-1716) writings. Against a prevalent view, which attributes a higher-order reflection account of phenomenal consciousness to Leibniz, it is argued that we should understand Leibniz as holding a first-order concep- tion of it. In this conception, the consciousness aspect of phenomenal consciousness is explained in terms of a specific type of attention. This (...) type of attention, in turn, is accounted for in terms of cognitive appetites aiming at knowledge about a repre- sented object by means of initiating cognitive operations on representational content. Furthermore, against the view that Leibniz holds a reifying account, it is argued that Leibniz accepts an epistemic account of phenomenal character. According to this view, the phenomenal character of phenomenally conscious states rests on the con- fusing effect of imperfect acts of attention directed towards representational contents. Holding this view, Leibniz finds fruitful middle ground between contemporary stan- dard positions like higher-order theories, representationalist conceptions, and qualia accounts of phenomenal consciousness. His position possesses resources to meet sev- eral objections these standard accounts are confronted with. (shrink)

This article re-examines Ned Block‘s ( 1997 , 2007 ) conceptual distinction between phenomenal consciousness and access consciousness. His argument that we can have phenomenally conscious representations without being able to cognitively access them is criticized as not being supported by evidence. Instead, an alternative interpretation of the relevant empirical data is offered which leaves the link between phenomenology and accessibility intact. Moreover, it is shown that Block’s claim that phenomenology and accessibility have different neural substrates is (...) highly problematic in light of empirical evidence. Finally, his claim that there can be phenomenology without cognitive accessibility is at odds with his endorsement of the 'same-order-theory' of consciousness. (shrink)

We present Birch and colleagues with a dilemma. On one interpretation, they aim to chart the distribution of a sort of minimal perceptual awareness across the animal kingdom, where that awareness can be fully characterized in third-person psychological terms. On this interpretation, the project is worthy but dull, since it doesn’t touch the question that has excited most people: whether other animals are phenomenally conscious. On an alternative interpretation, in contrast, they hope to resolve this latter question, arguing that (...) class='Hi'>phenomenal consciousness is extremely widespread. But if this is their intention, then their argument begs the question. (shrink)

Carruthers’s central project in Phenomenal Consciousness is to naturalize consciousness. Given the vast success of naturalism in science, he maintains that we should require powerful reasons to abandon it when constructing philosophical theories of consciousness. Unsurprisingly, he then argues that there are no such reasons. In particular, he claims that the well-known arguments of Thomas Nagel and Frank Jackson fail, as do inverted and absent qualia arguments. Carruthers’s main strategy for defusing these arguments involves first distinguishing (...) a “thin” notion of property from a “thick” notion of property and then arguing that the various antinaturalistic arguments conflate these two different notions. Although he admits that the antinaturalist may not find these considerations wholly convincing, he construes the dialectical situation in such a way as to relieve him of any obligation to do more. As long as it can be shown that the antinaturalistic arguments are not obviously successful, which he takes himself to have done, Carruthers claims that the presumption in favor of naturalism remains. Thus, a theory of consciousness must be compatible with the following two naturalistic claims: first, all mental events occur in accordance with causal laws; and second, all mental events can be given a reductive explanation in physical terms.

The target article appeals to recent empirical data to support the idea that there is more to phenomenality than is available to access consciousness. However, this claim is based on an unwarranted assumption, namely, that some kind of cortical processing must be phenomenal. The article also considerably weakens Block's original distinction between a truly nonfunctional phenomenal consciousness and a functional access consciousness. The new form of phenomenal consciousness seems to be a poor-man's cognitive (...) access. (shrink)

This paper controverts the ability of intentionalism about perception to account for unique epistemic significance of phenomenal consciousness. More specifically, the intentionalist cannot explain the latter without denying two well-founded claims: the transparency of experience, and the possibility of unconscious perception. If they are true, intentionality of perception entails that phenomenal consciousness has no special epistemic role to play. Although some intentionalists are ready to bite this bullet, by doing so they effectively undermine one of the (...) standard motivations of their view, i.e. the claim that perceptual experiences justify beliefs. Consequently, whatever reason might there be to think that phenomenal consciousness has unique epistemic import, it is also a reason to reject intentionalism. I recommend replacing the latter with an unorthodox formulation of relationalism about perception. (shrink)

Evidence for unconscious semantic representation suggests that a cognitive unconscious exists. Phenomenal consciousness cannot easily be shown to deal with complex cognitive operations such as those involved in language translation and creativity. A self-organising phenomenal consciousness that controls brain functions also runs into mind/body problems (well recognised in the consciousness studies literature) that Perruchet & Vinter must address.

In the past two decades a number of arguments have been given in favor of the possibility of phenomenal consciousness without attentional access, otherwise known as phenomenal overflow. This paper will show that the empirical data commonly cited in support of this thesis is, at best, ambiguous between two equally plausible interpretations, one of which does not posit phenomenology beyond attention. Next, after citing evidence for the feature-integration theory of attention, this paper will give an account of (...) the relationship between consciousness and attention that accounts for both the empirical data and our phenomenological intuitions without positing phenomenal consciousness beyond attention. Having undercut the motivations for accepting phenomenal overflow along with having given reasons to think that phenomenal overflow does not occur, I end with the tentative conclusion that attention is a necessary condition for phenomenal consciousness. -/- .

Money is a cultural construction, leukemia is not. In which category does phenomenal consciousness fit? The issue is clarified by a distinction between what cultural phenomena causally influence and what culture constitutes. Culture affects phenomenal consciousness but it is ridiculous to suppose that culture constitutes it, even in part.

The distinction between phenomenal and access consciousness is central to debates about consciousness and its neural correlates. However, this distinction has often been limited to the domain of perceptual experiences. On the basis of dream phenomenology and neuroscientific findings this paper suggests a theoretical framework which extends this distinction to dreaming, also in terms of plausible neural correlates. In this framework, phenomenal consciousness is involved in both waking perception and dreaming, whereas access consciousness is (...) weakened, but not fully eliminated, during dreaming. However, access consciousness is more active during lucid dreaming. The proposed framework accounts for different aspects of dream phenomenology, including levels of integration of perceptual, cognitive and affective features in dreams, bizarreness, dream amnesia and the occurrence of meta-awareness and accessibility in lucid dreaming. Self-related experiences and their neural substrates are suggested to be differently involved in waking cognition and dreaming. Further, phenomenal consciousness during both waking and dream experiences involve widespread recurrent interactions and convergence-divergence zones in the thalamo-cortico-limbic system, activated before conscious access in global workspace areas. Finally, we discuss the relationships of the proposed framework with other neurocognitive theories and models of consciousness and major theories of dreaming, and propose novel experimental predictions.

We evaluate the role of embodiment in ordinary mental state ascriptions. Presented are five experiments on phenomenal state ascriptions to disembodied entities such as ghosts and spirits. Results suggest that biological embodiment is not a central principle of folk psychology guiding ascriptions of phenomenal consciousness. By contrast, results continue to support the important role of functional considerations in theory of mind judgments.

Upshot: Douglas Robinson argues for a revision of the extended mind theory that incorporates intersubjectivity and qualia. Robinson argues that “material extendedness” is less important than accounting for the subjective experience of what he terms “body-becoming-mind,” and that this experience, rather than mere computational equivalence between intra- and transcranial cognition, is the strongest argument in favour of the EMT.

This paper aims to uncover where the disagreement between illusionism and anti-illusionism about phenomenal consciousness lies fundamentally. While illusionists claim that phenomenal consciousness does not exist, many philosophers of mind regard illusionism as ridiculous, stating that the existence of phenomenal consciousness cannot be reasonably doubted. The question is, why does such a radical disagreement occur? To address this question, I list various characterisations of the term “phenomenal consciousness”: (1) the what-it-is-like locution, (2) (...) inner ostension, (3) thought experiments such as philosophical zombies, inverted qualia and Mary’s room, (4) scientific knowledge about secondary properties, (5) theoretical properties such as being ineffable and being intrinsic, and (6) appearance/reality collapse. Then I examine whether each characterization provides (i) a dubitable sense of phenomenal consciousness in which the existence of phenomenal consciousness can be reasonably doubted, (ii) an indubitable sense in which its existence cannot be reasonably doubted, or (iii) a gray sense in which it is controversial whether its existence can be reasonably doubted. By doing so, I show that there is no single sense of phenomenal consciousness in which illusionists and anti-illusionists disagree whether the existence of phenomenal consciousness can be reasonably doubted. I conclude that the disagreement between illusionists and anti-illusionists is fundamentally terminological: while illusionists adopt a dubitable sense of phenomenal consciousness, anti-illusionists adopt an indubitable sense of phenomenal consciousness. Because of the extreme vagueness and ambiguity of the term “phenomenal consciousness”, illusionists and anti-illusionists fail to see that they talk about different senses of phenomenal consciousness.

Given the recent interest in the subjective or phenomenal dimension of consciousness it is no wonder that many authors have once more started to speak of the need for pheno- menological considerations. Often however the term ‘phenomenology’ is being used simply as a synonym for ‘folk psychology', and in our article we argue that it would be far more fruitful to turn to the argumentation to be found within the continental tradition inaugurated by Husserl. In order to exemplify (...) this claim, we criticize Rosenthal's higher-order thought theory as well as Strawson's recent contribution in this journal, and argue that a phenomenological analysis of the nature of self-awareness can provide us with a more sophisticated and accurate model for understanding both phenomenal consciousness and the notion of self.
