Monitoring approaches to consciousness claim that a mental state is conscious when it is suitably monitored. Higher-order monitoring theory makes the monitoring state and the monitored state logically independent. Same-order monitoring theory claims a constitutive, non-contingent connection between the monitoring state and the monitored state. In this paper, I articulate different versions of the same-order monitoring theory and argue for its supremacy over the higher-order monitoring theory.

Within the philosophy of mind, consciousness is currently understood as the expression of one or other cognitive modality, either intentionality , transparency , subjectivity or reflexivity . However, neither intentionality, subjectivity nor transparency adequately distinguishes conscious from nonconscious cognition. Consequently, the only genuine index or defining characteristic of consciousness is reflexivity, the capacity for autonoetic or self-referring, self-monitoring awareness. But the identification of reflexivity as the principal index of consciousness raises a major challenge in relation to the cognitive mechanism responsible (...) for operationalizing such a reflexive state. Current reliance by higher-order and intrinsic self-representational theories on self-representing data structures to achieve reflexive self-awareness is highly problematic, suggesting a solution in terms of a self-referential processing regime.

It is argued that there is no fallacy in the reasoning in the example of the thirsty blindsight subject, on one reconstruction of that reasoning. Neither the case of orgasm nor the case of a visual versus an auditory experience as of something overheard shows that phenomenal content is not representational.

Should we distinguish between access and phenomenal consciousness? Block says yes and that various pathologies of consciousness support and clarify the distinction. The commentary charge that the distinction is neither supported nor clarified by the clinical data. It recommends an alternative reading of the data and urges Block to clarify the distinction.

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.

Phenomenology and physiology become commensurable through a self-organizational physiology and an "enactive" view of consciousness. Self-organizing processes appropriate and replace their own needed substrata, rather than merely being caused by interacting components. Biochemists apply this notion to the living/nonliving distinction. An enactive approach sees consciousness as actively executed by an agent rather than passively reacting to stimuli. Perception does not result from mere stimulation of brain areas by sensory impulses; unless motivated organismic purposes first anticipate and "look for" emotionally relevant.stimuli, (...) brain-sensory processing is not accompanied by perceptual consciousness. To see a soccer ball requires looking for it in the right place. The sell-organizing, emotionally motivated agent instigates this looking-for activity. (shrink)

In this article, which is fourth in a series of six articles, I address the fourth concept of consciousness that the Oxford English Dictionary defines in its six main entries under the word consciousness. I first introduce this fourth concept, the concept of consciousness4. by identifying the previous three OED concepts of consciousness, which I have already discussed in this series of articles, and by indicating how that to which we make reference, respectively, by means of those three concepts is (...) related to the referents of the concept of consciousness4. I then address the latter concept more directly by pursuing for the remainder of the article where the OED's fourm entry leads. Among other things, I am led to consider two competing accounts of consciousness4 that figure prominently in the OED entry, namely the intrinsic, self-intimational account of William Hamilton and the inner-eye, perceptionlike account of John Locke. Both kinds of account are very much with us today. (shrink)

Consciousness is a mongrel concept: there are a number of very different "consciousnesses." Phenomenal consciousness is experience; the phenomenally conscious aspect of a state is what it is like to be in that state. The mark of access-consciousness, by contrast, is availability for use in reasoning and rationally guiding speech and action. These concepts are often partly or totally conflated, with bad results. This target article uses as an example a form of reasoning about a function of "consciousness" based on (...) the phenomenon of blindsight. Some information about stimuli in the blind field is represented in the brains of blindsight patients, as shown by their correct "guesses," but they cannot harness this information in the service of action, and this is said to show that a function of phenomenal consciousness is somehow to enable information represented in the brain to guide action. But stimuli in the blind field are BOTH access-unconscious and phenomenally unconscious. The fallacy is: an obvious function of the machinery of access-consciousness is illicitly transferred to phenomenal consciousness. (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.

The word ?consciousness? is notoriously ambiguous. This is mainly because it is not a term of art, but a mundane word we all use quite frequently, for different purposes and in different everyday contexts. In this paper, I discuss consciousness in one specific sense of the word. To avoid the ambiguities, I introduce a term of art ? intransitive self-consciousness ? and suggest that this form of self-consciousness is an essential component of the folk notion of consciousness. I then argue (...) for a specific account of consciousness as intransitive self-consciousness. According to this account, a mental state is conscious iff it represents its own occurrence. The argument is a ?modernizing? modification of an older argument due to Aristotle and Brentano. (shrink)

One of the promising approaches to the problem of consciousness has been the Higher-Order Monitoring Theory of Consciousness. According to the Higher-Order Monitoring Theory, a mental state M of a subject S is conscious iff S has another mental state, M*, such that M* is an appropriate representation of M. Recently, several philosophers have developed a Higher-Order Monitoring theory with a twist. The twist is that M and M* are construed as entertaining some kind of constitutive relation, rather than being (...) logically independent of each other. We may call this the Same-Order Monitoring Theory of Consciousness. In this paper, I discuss the nature of the Same-Order Monitoring Theory and argue for its superiority over the more traditional Higher-Order Monitoring Theory. (shrink)

To demonstrate that a fallacy is committed, Block needs to convince us of two things: first, that the concept of phenomenal consciousness is distinct from that of access consciousness, and second, that it picks out a different property from that of access consciousness. I raise doubt about both of these claims, suggesting that the concept of a phenomenal property is the concept of a property to which we have a special sort of access.

This commentary offers two criticisms of Block's account of phenomenal consciousness and a brief sketch of a rival account. The negative points are that monitoring consciousness also involves the possession of certain states and that phenomenal consciousness inevitably involves some sort of monitoring. My positive suggestion is that “phenomenal consciousness” may refer to our ability to monitor the rich but preconceptual states that retain perceptual information for complex processing.

Block's P-/A-consciousness distinction rules out P's involving a specific kind of cognitive access and commits him to a “strong” Pconsciousness. This not only confounds plausible research in the area but betrays an anosognosia about Wittgenstein's diagnosis about our philosophical “introspection” of mysterious inner processes.

If phenomenal consciousness is distinct from the computationally based access-consciousness that controls overt behavior, how can I tell which things (other than myself) enjoy phenomenal consciousness? And if phenomenal consciousness 'plays no role in controlling overt behavior, how do human bodies come to write target articles arguing for the existence of phenomenal consciousness?

Block's notion of P-consciousness catches too much in its net. He would do better to exclude all states that do not have a sensory component. I question what he says about my work with the “blind” monkey, Helen.

The differences Block attempts to capture with his putative distinction between P-consciousness and A-consciousness are more directly and perspicuously handled in terms of differences in richness of content and degree of influence. Block's critiques, based on his misbegotten distinction, evaporate on closer inspection.

Although information-processing theories cannot provide a full explanatory account of P-consciousness, there is less conflation and confusion in cognitive psychology than Block suspects. Some of the reasoning that Block criticises can be interpreted plausibly in the light of a folk psychological view of the relation between P-consciousness and A-consciousness.

This paper reports on the Kuhnian revolution now occurring in neuropsychology that is finally supportive of and friendly to phenomenology – the “enactive” approach to the mind-body relation, grounded in the notion of self-organization, which is consistent with Husserl and Merleau-Ponty on virtually every point. According to the enactive approach, human minds understand the world by virtue of the ways our bodies can act relative to it, or the ways we can imagine acting. This requires that action be distinguished from (...) passivity, that the mental be approached from a first person perspective, and that the cognitive capacities of the brain be grounded in the emotional and motivational processes that guide action and anticipate action affordances. It avoids the old intractable problems inherent in the computationalist approaches of twentieth century atomism and radical empiricism, and again allows phenomenology to bridge to neuropsychology in the way Merleau-Ponty was already doing over half a century ago.

Mack and Rock show evidence that no consciousperception occurs without a prior attentiveact. Subjects already executing attention taskstend to neglect visible elements extraneous tothe attentional task, apparently lacking evenbetter-than-chance ``implicit perception,''except in certain cases where the unattendedstimulus is a meaningful word or has uniquepre-tuned salience similar to that ofmeaningful words. This is highly consistentwith ``enactive'' notions that consciousnessrequires selective attention via emotional subcortical and limbic motivationalactivation as it influences anterior attentionmechanisms. Occipital activation withoutconsciousness suggests that motivated search,enacted through the organism's (...) subcorticalmotivational functions, is needed beforevisual stimulation engenders consciousness.This enactive view – that searching for,rather than receiving or processing input isthe basis of consciousness – was slow ingaining acceptance lacking empirical evidenceof this kind, combined with thestimulus-response assumption that brain eventssubserving perceptual consciousness must resultfrom transformation of perceptual input ratherthan from the organism's self-regulatedactivity as manifested through subcorticalactivity. Implicit perception occurring withword priming is ``paradoxical'' according to Mackand Rock, suggesting late selection forattention after extensive unconsciousprocessing, while most trials involvingnonverbal rather than verbal images mightsuggest earlier selection, sinceunattended objects are unseen, apparently evenimplicitly. This paper argues that anteriorand subcortical motivational mechanisms play animportant role in early selection; posteriormechanisms then unconsciously enhance signals;if data survive early gating andcorticothalamic enhancement, then still further anterior-limbic loops motivatedlyactivate ``image schemas'' resonating withposterior nonconscious processing; at thatpoint, consciousness occurs.

. When I have a conscious experience of the sky, there is a bluish way it is like for me to have that experience. We may distinguish two aspects of this "bluish way it is like for me": the bluish aspect and the for-me aspect. Let us call the bluish aspect of the experience its qualitative character and the for-me aspect its subjective character . What is this elusive for-me-ness, or subjective character , of conscious experience? In this paper, I (...) examine six different attempts to account for subjective character in terms of the functional and representational properties of conscious experiences. After arguing against the first five, I defend the sixth. (shrink)

Theories of what it is for a mental state to be conscious must answer two questions. We must say how we're conscious of our conscious mental states. And we must explain why we seem to be conscious of them in a way that's immediate. Thomas Natsoulas distinguishes three strategies for explaining what it is for mental states to be conscious. I show that the differences among those strategies are due to the divergent answers they give to the foregoing questions. Natsoulas (...) finds most promising the strategy that amounts to the higher-order-thought hypothesis that I've defended elsewhere. But he raises a difficulty for it, which he thinks probably can be met only by modifying that strategy. I argue that this is unnecessary. The difficulty is a special case of a general question, the answer to which is independent of any issues about consciousness. So it's no part of a theory of consciousness to address the problem, much less solve it. Moreover, the difficulty seems to have intuitive force only given the picture that underlies the other two explanatory strategies, which both Natsoulas and I reject. (shrink)

For nearly a decade, David Rosenthal has proposed that a mental state M of a creature C is conscious just in case C has a suitable higher-order thought directed toward M. While this theory has had its share of criticism in recent years, I believe that the real difficulties have been ignored. In this essay, I show that the presence of a higher order is insufficient for conscious experience, even if we suppose that the thought satisfies the constraints that Rosenthal (...) lists . The only way Rosenthal's view could possibly yield sufficient conditions is by requiring that the higher-order thought be suitably causally related to its object. Yet, as I also show, the only causal constraint strong enough to do the job is not only ill-motivated but probably false. (shrink)

A-consciousness may be regarded as the visibility of information that is the output of a process within a community of other processes. The most prominent function of “public” dissemination of information is giving access to it to processes whose relevance is not clear at the moment of dissemination. The function of P-consciousness may be outside the realm of cognition.

Block seems to propose untested answers to empirical questions. Whether consciousness is a “mongrel problem,” rather than a single core fact with many facets, is an empirical issue. Likewise, the intimate relationship between personal consciousness and global access functions cannot be decided pretheoretically. This point is demonstrated by the reader's private experience of foveal versus parafoveal vision, and for conscious versus unconscious representation of the many meanings of common words.

With some help from the commentators, a few adjustments to the characterizations of A-consciousness and P-consciousness can avoid some trivial cases of one without the other. But it still seems that the case for the existence of P without A is stronger than that for A without P. If indeed there can be P without A, but not A without P, this would be a remarkable result that would need explanation.

I criticize Block's examples of P-consciousness and A-consciousness for being flawed and the notion of A-consciousness for not being a notion of consciousness at all. I argue that an empirically important distinction can be made between behavior that is supported by an underlying conscious experience and behavior that is brought about by nonconscious action-control mechanisms. This distinction is different from that made by Block.

In Feeling of Knowing cases, subjects have a form of consciousness about the presence of a content (such as an item of information) without having access to it. If this phenomenon can be correctly interpreted as having to do with consciousness, then there would be a P-conscious mental experience which is dissociated from access.

One can share Block's aim of distinguishing “phenomenal” experience from cognitive function and agree with much in his views, yet hold that the inclusion of representational content within phenomenal content, if only in certain spatial cases, obscures this distinction. It may also exclude some modular theories, although it is interestingly suggestive of what may be the limits of the phenomenal penetration of the representational mind.

Some cases of prosopagnosia involve a highly circumscribed loss of A-consciousness. When seen in this way they offer further support for the arguments made in Block's target article.

Block has attempted to reduce the confusion and controversy concerning the term “consciousness” by suggesting that there are two forms or types of consciousness, each of which has several characteristics or properties. This suggestion appears to further becloud the topic, however. Perhaps consciousness cannot be defined adequately and should not be considered as a topic that can be studied scientifically.

Blocks distinction between “phenomenal feel” consciousness and “thought/cognition” consciousness is a cultural construction. Consciousness (and its “subspecies”) is not a natural kind. Some crosscultural data are presented to support this.

Although not the main point of his target article, Block defends the view that perception and awareness of perception could be functions of different brain systems. I will argue that the available data do not support this view, and that Block's defense of the view rests on problematic eonstruals of the “executive system” and of the components of information-processing models.

The information processing that constitutes accessconsciousness is not sufficient to make a representational state conscious in any sense. Standard examples of computation without consciousness undermine A-consciousness, and Block's cases seem to derive their plausibility from a lurking phenomenal awareness. That is, people and other minded systems seem to have access-consciousness only insofar as the state accessed is a phenomenal one, or the state resulting from access is phenomenal, or both.

In response to the objection that his “access-consciousness” is not really consciousness but a matter of the availability of certain information for certain kinds of processing, Block will probably have to argue that consciousness in a more basic, familiar, traditional sense is an essential component of any instance of access-consciousness and thus justifies the name.

In common sense consciousness has a fairly determinate content – the (single) way an experience feels, the (single) line of thought being consciously followed. The determinacy of the object may be achieved by linking Block's two concepts, so that as long as we hold on to the determinacy of content we are unable to separate P and A.

As an advocate of the empirical method in both science and philosophy, Reid believed that the central method for studying the mind should be internal observation, whose evidence he believed to be the most reliable in comparison with all other mental operations. The fact that his contemporary “science of mind” was not as highly developed as the natural sciences was explained by Reid to be the fault of philosophers, such as John Locke, who “confounded” two completely different powers of the (...) mind: consciousness and reflection. In this paper I will present Reid's criticism of Locke, as well as Reid's own attempt to distinguish between consciousness and reflection, and the difficulties he is facing in this process. The paper concludes that Reid failed to depart from the essential Lockean characterizations of inner awareness, because of his failure to dissociate from premises he shares with Locke – such as the belief that we are conscious of all our thoughts, and the primacy of the introspective method in studying the mind. Therefore, while narrowing his concept of consciousness to an internal-sense, perceiving only present mental operations, he broadens respectively his concept of reflection. (shrink)

Block contends that the concept of consciousness is a mongrel concept and that researchers go astray by conflating different notions of “consciousness.” This is certainly true. In fact, it is truer than Block acknowledges, because his own notion of P-consciousness runs together two, or arguably three, quite different and separable features of a sensory state.

Basically agreeing with Block regarding the need for a distinction between P- and A-consciousness, I characterize the problem somewhat diflerently, relating it more directly to the explanatory gap. I also speculate on the relation between the two forms of consciousness, arguing that some notion of access is essentially involved in phenomenal experience.

Block's cases of superblindsight, the pneumatic drill, and the Sperling experiments do not show that P-consciousness and Aconsciousness can come apart. On certain tendentious but not implausible construals of the concepts of P- and A-consciousness, they refer to the same psychological phenomenon.

This thesis examines the relation between self-deception and self-consciousness. It has been argued that, if we follow the literalist and take self-deception at face value – as a deception that is intended by, and imposed on, one and the same self-conscious subject – then self-deception is impossible. It will incur the Dynamic Problem that, being aware of my intention to self-deceive, I shall see through my projected self-deceit from the outset, thereby precluding its possibility. And it will incur the following (...) Static Problem. Qua self-deceiver, I shall believe not-P, but – qua self-deceived – I shall believe P. We shall then have to explain how I can sustain contradictory beliefs in full self-awareness. I argue that this rejection of literalism about self-deception rests on error. First, it misunderstands what literalism holds. Properly understood, literalism does not require the simultaneous commitment to contradictory beliefs. Second, it misunderstands the relation between self-deception and self-consciousness – and that is my primary focus. The phenomenology of self-deception reveals that the self-deceiver experiences the following tension. She is somehow aware of her self-deception as such. Yet also, she misrepresents that self-deception to herself as being a sincere commitment to the truth – so, in that sense, she is not aware of her self-deceit as such. To capture this tension, we require a theory of self-consciousness – independently defensible in its own right – that will meet this twofold requirement, of permitting the self-deceiver not to see what is right before her gaze. The rejection of literalism presupposes that no theory of self-consciousness can meet this twofold requirement.I argue that this twofold requirement can be met. The first part of this thesis offers a detailed defence of a theory of self-consciousness. The second part shows how this theory of self-consciousness can faithfully capture the tension of self-deception, while eschewing the Dynamic and Static Problems. It thereby claims to vindicate the literalist's position. (shrink)

A “fallacy” is something like the sense-datum fallacy, involving a logically invalid argument. A “conflation” is something like Block's conflation of the (alleged) raw feel of an experience with what it is like to have the experience. Trivially, a self is conscious of something only if it accesses it. Substantive issues concern the nature of the conscious self and the nature of access.

Combines phenomenology with the "enactivist" approach to consciousness theory and recent emotion research to explore the way self-motivated action plans shape selective attention, exploration, and ultimately the mind's interpretation of reality - in philosophy, psychology, cultural awareness, and our personal lives.

Propositions as to the nature of consciousness, based on disorders of perception that result from brain damage, and taking insufficient account of the numerous ways in which normal subjects may deviate from that “usual” sequence of events (input → subjective awareness → output) risk increasing rather than diminishing any existing confusion about the function of consciousness.

Additional experiments show that P-consciousness and A consciousness can be empirically dissociated for the theoretically so phisticated observer. Phenomenal consciousness can have several degrees that are indirectly measurable.

Block's distinction between phenomenal and access consciousness is accepted, and it is agreed that one may be found without the other, but his account of the distinction is challenged. Phenomenal consciousness is perceptual consciousness, and it is a matter of gaining information of a detailed, nonverbal sort about the subject's body and environment. Access consciousness is good, old-fashioned introspection.
