According to commonsense psychology, one is conscious of everything that one pays attention to, but one does not pay attention to all the things that one is conscious of. Recent lines of research purport to show that commonsense is mistaken on both of these points: Mack and Rock (1998) tell us that attention is necessary for consciousness, while Kentridge and Heywood (2001) claim that consciousness is not necessary for attention. If these lines of research were successful they would (...) have important implications regarding the prospects of using attention research to inform us about consciousness. The present essay shows that these lines of research are not successful, and that the commonsense picture of the relationship between attention and consciousness can be. (shrink)
The search for neural correlates of consciousness (or NCCs) is arguably the cornerstone in the recent resurgence of the science of consciousness. The search poses many difficult empirical problems, but it seems to be tractable in principle, and some ingenious studies in recent years have led to considerable progress. A number of proposals have been put forward concerning the nature and location of neural correlates of consciousness. A few of these include.
This paper is a response to the 26 commentaries on my paper "Facing Up to the Problem of Consciousness". First, I respond to deflationary critiques, including those that argue that there is no "hard" problem of consciousness or that it can be accommodated within a materialist framework. Second, I respond to nonreductive critiques, including those that argue that the problems of consciousness are harder than I have suggested, or that my framework for addressing them is flawed. Third, (...) I address positive proposals for addressing the problem of consciousness, including those based in neuroscience and cognitive science, phenomenology, physics, and fundamental psychophysical theories.

Ned BlockÕs influential distinction between phenomenal and access consciousness has become a staple of current discussions of consciousness. It is not often noted, however, that his distinction tacitly embodies unargued theoretical assumptions that favor some theoretical treatments at the expense of others. This is equally so for his less widely discussed distinction between phenomenal consciousness and what he calls reflexive consciousness. I argue that the distinction between phenomenal and access consciousness, as Block draws it, is (...) untenable. Though mental states that have qualitative character plainly differ from those with no mental qualities, a mental stateÕs being conscious is the same property for both kinds of mental state. For one thing, as Block describes access consciousness, that notion does not pick out any property that we intuitively count as a mental stateÕs being conscious. But the deeper problem is that BlockÕs notion of phenomenal consciousness, or phenomenality, is ambiguous as between two very different mental properties. The failure to distinguish these results in the begging of important theoretical questions. Once the two kinds of phenomenality have been distinguished, the way is clear to explain qualitative consciousness by appeal to a model such as the higher-order-thought hypothesis.

My target in this paper is "theories of consciousness". There are many theories of consciousness around, and my view is that they are all misconceived. Consciousness is not a normal scientific subject, and needs handling with special care. It is foolhardy to jump straight in and start building a theory, as if consciousness were just like electricity or chemical valency. We will do much better to reflect explicitly on our methodology first. When we do this, we (...) will see that theories of consciousness are trying to answer a question that isn't there. (shrink)
My goal is to try to understand the intentionality of consciousness from a naturalistic perspective. My basic methodological assumption is that embodied agents, through their sensory-motor, affective, and cognitive activities directed at objects, engage in intentional relations with these objects. Furthermore, I assume that intentional relations can be viewed from a first- and a third-person perspective. What is called primary consciousness is the first-person perspective of the agent engaged in a current intentional relation. While primary consciousness posits (...) an implicit. (shrink)
It is widely assumed that ‘consciousness’ (and its cognates) is multiply ambiguous within the consciousness literature. Some alleged senses of the term are access consciousness, phenomenal consciousness, state consciousness, creature consciousness, introspective consciousness, self consciousness, to name a few. In the paper I argue for two points. First, there are few if any good reasons for thinking that such alleged senses are genuine: ‘consciousness’ is best viewed as univocal within the literature. (...) The second point is that researchers would do best to avoid the semantics of ‘consciousness’, since resorting to “semantic ascent” typically serves no clear purpose in the case of consciousness, and confuses matters more than anything else.

In the past decade, the notion of a neural correlate of consciousness (or NCC) has become a focal point for scientific research on consciousness (Metzinger, 2000a). A growing number of investigators believe that the first step toward a science of consciousness is to discover the neural correlates of consciousness. Indeed, Francis Crick has gone so far as to proclaim that ‘we … need to discover the neural correlates of consciousness.… For this task the primate visual (...) system seems especially attractive.… No longer need one spend time attempting … to endure the tedium of philosophers perpetually disagreeing with each other. Con- sciousness is now largely a scientific problem’ (Crick, 1996, p. 486).2 Yet the question of what it means to be a neural correlate of consciousness is actually far from straightforward, for it involves fundamental empirical, methodological, and _philosophical _issues about the nature of consciousness and its relationship to the brain. Even if one assumes, as we do, that states of consciousness causally depend on states of the brain, one can nevertheless wonder in what sense there is, or could be, such a thing as a neural correlate of consciousness.

The strategy of divide and conquer is usually an excellent one, but it all depends on how you do the carving. Chalmer's attempt to sort the "easy" problems of consciousness from the "really hard" problem is not, I think, a useful contribution to research, but a major misdirector of attention, an illusion-generator. How could this be? Let me describe two somewhat similar strategic proposals, and compare them to Chalmers' recommendation.
Introspection stands at the interface between two major currents in philosophy and related areas of science: on the one hand, there are metaphysical and scientific questions about the nature of consciousness; and on the other hand, there are normative and epistemological questions about the nature of self-knowledge. Introspection seems tied up with consciousness, to the point that some writers define consciousness in terms of introspection; and it is also tied up with self-knowledge, since introspection is the distinctive (...) way in which we come to know about ourselves and, in particular, about our own conscious mental states, processes and events. Each of these topics – consciousness and self-knowledge – has generated an extensive philosophical literature in its own right. But despite some notable exceptions, the relationship between consciousness and self-knowledge has been curiously neglected and remains poorly understood. Indeed, until quite recently, the sub-fields of philosophy of mind and epistemology were pursued largely in isolation from one another. Recent philosophy of mind has been dominated by metaphysical questions about the nature of consciousness and its place in the physical world, while much less attention has been devoted to questions about the epistemic role of consciousness as a source of knowledge and justified belief. Similarly, recent epistemology has been organized around questions about the nature of knowledge and justified belief, but much of this discussion has developed independently of recent work in philosophy of mind about the nature of consciousness. The impetus behind this volume is to bring together these two lines of research by exploring the nature of introspection, which lies at the intersection between consciousness and self-knowledge. This volume collects fourteen new essays and one reprinted essay in which the interplay between concerns in epistemology and the philosophy of mind is a major focus. (shrink)
Todd Moody’s Zombie Earth thought experiment is an attempt to show that ‘conscious inessentialism’ is false or in need of qualification. We defend conscious inessentialism against his criticisms, and argue that zombie thought experiments highlight the need to explain why consciousness evolved and what function(s) it serves. This is the hardest problem in consciousness studies.
Intentionality is usually defined as the directedness of the mind toward something other than itself. My desire for a cold beer is directed at the cold beer in front of me. Much of consciousness is intentional, my conscious experiences are usually directed at something. However, conscious experiences typically have a phenomenal character: there is something it is like for me to see the deep blue of the Pacific Ocean and to feel the warm water lapping over my feet, and (...) to smell the briny breeze. An important question to answer concerning the relationship between intentionality and consciousness is whether all conscious states are intentional? Another question concerns the explanatory priority of intentionality and phenomenal character: Can phenomenal character be explained in terms of intentionality? Or is it the case that intentionality should be understood in terms of phenomenology? Philosophers from the analytic, phenomenological, and naturalistic traditions have all made important contributions to our understanding of intentionality and consciousness. Some philosophers, such as Dretske, think that our phenomenology is intentionally structured. Others, such as Horgan and Tienson think that intentionality is fundamentally determined by our phenomenology. This looks like an impasse; however it may well be resolved by a combination of contemporary accounts of representation combined with an embodied phenomenology. (shrink)
This article makes five main points. (1) Individual human consciousness is formed in the dynamic interrelation of self and other, and therefore is inherently intersubjective. (2) The concrete encounter of self and other fundamentally involves empathy, under- stood as a unique and irreducible kind of intentionality. (3) Empathy is the precondi- tion (the condition of possibility) of the science of consciousness. (4) Human empathy.
Theories about the evolution of consciousness relate in an intimate way to theories about the distribution of consciousness, which range from the view that only human beings are conscious to the view that all matter is in some sense conscious. Broadly speaking, such theories can be classified into discontinuity theories and continuity theories. Discontinuity theories propose that consciousness emerged only when material forms reached a given stage of evolution, but propose different criteria for the stage at which (...) this occurred. Continuity theories argue that in some primal form, consciousness always accompanies matter and as matter evolved in form and complexity consciousness co-evolved, for example into the forms that we now recognise in human beings. Given our limited knowledge of the necessary and sufficient conditions for the presence of human consciousness in human brains, all options remain open. On balance however continuity theory appears to be more elegant than discontinuity theory. (shrink)
In this commentary I criticize David Rosenthal’s higher order thought theory of consciousness (HOT). This is one of the best articulated philosophical accounts of consciousness available. The theory is, roughly, that a mental state is conscious in virtue of there being another mental state, namely, a thought to the effect that one is in the first state. I argue that this account is open to the objection that it makes “HOT-zombies” possible, i.e., creatures that token higher order mental (...) states, but not the states that the higher order states are about. I discuss why none of the ways to accommodate this problem within HOT leads to viable positions. (shrink)
Newcomers to the philosophy of mind are sometimes resistant to the idea that pain is a mental state. If asked to defend their view, they might say something like this: pain is a physical state, it is a state of the body. A pain in one’s leg feels to be in the leg, not ‘in the mind’. After all, sometimes people distinguish pain which is ‘all in the mind’ from a genuine pain, sometimes because the second is ‘physical’ while the (...) first is not. And we also occasionally distinguish mental pain (which is normally understood as some kind of emotional distress) from the ‘physical pain’ one feels in one’s body. So what can be meant by saying that pain is a mental state? Of course, it only takes a little reflection shows that this naive view is mistaken. Pain is a state of consciousness, or an event in consciousness, and whether or not all states of mind are conscious, it is indisputable that only minds, or states of mind, are conscious.2 But does the naive view tell us anything about the concept of pain, or the concept of mind? I think it does. In this paper, I shall give reasons for thinking that consciousness is a form of intentionality, the mind’s ‘direction upon its objects’. I shall claim that the consciousness involved in bodily sensations like pain is constituted by the mind’s direction upon the part or region of the body where the sensation feels to be. Given this, it is less surprising that the naive view of pain says what it does: the apparent ‘physicality’ of pain is a consequence of confusing the object of the intentional state—the part of the body in which the pain is felt—with the state of being in pain.

From the assumption that the presence of consciousness is detectable, in the first instance, only from behavioral indicators, I offer a proof to the effect that, with respect to any theory T that states that some particular state or process is the neural correlate of consciousness, there are always rival neural correlates that, from T’s perspective, can never be empirically ruled out. That's because, with respect to these states, the means of detecting consciousness is disrupted along with (...) the empirical test. Possible responses are discussed. (shrink)
Ayahuasca, a hallucinogen with profound consciousness- altering properties, has been increasingly utilized in recent studies (e.g., Strassman, 2001; Shanon, 2002a,b). However, other than Shanon's recent work, there has been little attempt to examine the effects of ayahuasca on perceptual, affective and cognitive experience, its relation to fringe consciousness or to pertinent personality variables. Twenty-one volunteers attending a seminar on ayahuasca were administered personality measures and a semi-structured interview about phenomenal qualities of their experience. Ayahuasca ingestion was associated with (...) profound alterations of temporal- spatial experiences including expansive space and slowed time. Ayahuasca use was also associated with positive emotional states, higher levels of fantasy proneness and psychological absorption and a greater openness to mystical experiences. Conversely, quickened time was associated with negative emotionality. The results are discussed within a multi-faceted model of fringe consciousness with a particular emphasis on Hunt's (1995) models of cross-modal translation as the basis for higher-order symbolic cognition and support James' (1890/1950) contention that fringe consciousness is essential to human cognition.

Perception is sensory awareness. Cognition is reflective awareness. Consciousness is awareness-as-such. In Indian psychology, as represented by Samkhya-Yoga and Advaita Vedanta systems, consciousness and mind are fundamentally different. Reality is the composite of being (sat), knowing (cit) and feeling (ananda). Consciousness is the knowledge side of the universe. It is the ground condition of all awareness. Consciousness is not a part or aspect of the mind. Mind is physical and consciousness is not. Consciousness does (...) not interact with the mind, the brain or any other physical objects or processes. Nor does it have any causative role in mental activity. Hence the existence of consciousness does not interfere or upset the apparently closed physical system. Mind in this view is the interfacing instrumentality that faces consciousness on one side and the brain and the rest of the physical world on the other. Mind is closely connected with the different systems of the brain. In normal perceptions, the mind takes the forms of objects via the channels of the sensory system and the processes in the brain. The forms themselves are non-conscious representations of the world of objects. The mental forms (vrittis) become conscious experiences in the light of the purusha. The vritti in sensory form is perception and with the reflection of the purusha it becomes cognition. All conscious perceptions are therefore cognitions. (shrink)
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.
Right now my conscious experience is directed at part of the world. It takes in some aspects of things around me and not others. Some bits of the world occupy my attention, other worldly goings on condition or colour the character of my current perceptual experience. I experience buildings in view through the window, the clothes in the corner of the room, the colour of the walls, the plate with breads, the coffee mugs, the smell of fresh laundry, the muffled (...) sounds of someone in the kitchen, the sounds from the street: a sequence of things that in turn capture my attention moment to moment. And all the while thoughts occur to me, modulating my conscious awareness. I have no doubt that the world and my place in it, together with my recent past history, explains the particular form my consciousness takes right now. But what shape does that explanation take? Things out there beyond the boundaries of my skin enter into the conscious events I undergo. The inner is in this way shaped and determined by those outer things that impress themselves on the mind. What is it, though, for consciousness of this kind to go on at all? (shrink)
Over a decade ago, I introduced a large-scale theory of the cognitive brain which explained for the first time how the human brain is able to create internal models of its intimate world and invent models of a wider universe. An essential part of the theoretical model is an organization of neuronal mechanisms which I have named the Retinoid Model (Trehub, 1977, 1991). This hypothesized brain system has structural and dynamic properties enabling it to register and appropriately integrate disparate foveal (...) stimuli into a perspectival, egocentric representation of an extended 3D world scene including a neuronally-tokened locus of the self which, in this theory, is the neuronal origin of retinoid space. As an integral part of the larger neuro-cognitive model, the retinoid system is able to perform many other useful perceptual and higher cognitive functions. In this paper, I draw on the hypothesized properties of this system to argue that neuronal activity within the retinoid structure constitutes the phenomenal content of consciousness and the unique sense of self that each of us experiences. -/- Trehub, A.

This paper distinguishes three conceptual problems that attend philosophical accounts of consciousness. The first concerns the problem of properly characterizing the nature of consciousness itself, the second is the problem of making intelligible the relation between consciousness and the physical, and the third is the problem of creating the intellectual space for a shift in philosophical framework that would enable us to deal adequately with the first two problems. It is claimed that physicalism, in both its reductive (...) and non-reductive forms, fails to deal adequately with either the first or second problem. The diagnosis of this failure is connected to the fact that consciousness cannot be treated in its own terms while being simultaneously fitted into an object-based conceptual schema. In light of this, it is proposed that a Bradleian version of absolute idealism may provide a metaphysical and epistemological framework which would enable us to recognize the conceptual diversity required to treat conscious phenomena on their own terms without forcing us to abandon naturalism.

One of the aspects of consciousness deserving of study is what might be called its subjective unity - the way in which, though conscious experience moves from object to object, and can be said to have distinct ‘states', it nevertheless in some sense apparently forms a singular flux divided only by periods of unconsciousness. The work of William James provides a valuable, and rather unique, source of analysis of this feature of consciousness; however, in my opinion, this component (...) of James’ theory of the mind has so far gone under-emphasized in the scholarly literature. This paper undertakes some philosophical geography, trying to draw out and elucidate some of the relevant ideas from James’ corpus, and also subjects those ideas to some analysis to try and assist in judgements of their current importance.

The standard behavioral index for human consciousness is the ability to report events with accuracy. While this method is routinely used for scientific and medical applications in humans, it is not easy to generalize to other species. Brain evidence may lend itself more easily to comparative testing. Human consciousness involves widespread, relatively fast low-amplitude interactions in the thalamocortical core of the brain, driven by current tasks and conditions. These features have also been found in other mammals, which suggests (...) that consciousness is a major biological adaptation in mammals. We suggest more than a dozen additional properties of human consciousness that may be used to test comparative predictions. Such homologies are necessarily more remote in non-mammals, which do not share the thalamocortical complex. However, as we learn more we may be able to make “deeper” predictions that apply to some birds, reptiles, large-brained invertebrates, and perhaps other species. (shrink)
The so-called 'higher-order thought' (HOT) theory of consciousness says that what makes a mental state conscious is the presence of a suitable higher-order thought directed at it (Rosenthal, 1986; 1990; 1993; 2002; 2004; Gennaro, 1996; 2004). The HOT theory has been or could be attacked from two apparently opposite directions. On the one hand, there is what Stubenberg (1998) has called 'the problem of the rock' which, if successful, would show that the HOT theory proves too much. On the (...) other hand, it might also be alleged that the HOT theory does not or cannot address the so-called 'hard problem' of phenomenal consciousness. If so, then the HOT theory would prove too little. We might say, then, that the HOT theory is arguably between a rock and a hard place. In this paper, I critically examine these objections and defend the HOT theory against them. In doing so, I hope to show that the HOT theory, or at least some version of it, neither proves too little nor too much, but is just right. I also show that these two objections are really just two sides of the same coin, and that the HOT theory is immune from David Chalmers' (1995; 1996) criticisms of other attempted reductionist accounts of consciousness.

same thing, so the two concepts of consciousness may come to the same thing in the brain. The focus of this paper is on the problems that arise when these two concepts of consciousness are conflated. I will argue that John Searle’s reasoning about the function of consciousness goes wrong because he conflates the two senses. And Francis Crick and Christof Koch fall afoul of the ambiguity in arguing that visual area V1 is not part of the (...) neural correlate of consciousness. Crick and Koch’s work raises issues that suggest that these two concepts of consciousness may have different (though overlapping) neural correlates--despite Crick and Koch’s implicit rejection of this idea.            I will start with two quotations from Searle. You will see what appears to be a contradiction, and I will later claim that the appearance of contradiction can be explained if one realizes that he is using two different concepts of consciousness. I’m not going to explain yet what the two concepts of consciousness are. That will come later, after I’ve presented Searle’s apparent contradiction and Crick and Koch’s surprising argument.Â.

Quite a few recent models are rapidly introducing new concepts describing different levels of consciousness. This situation is getting confusing because some theorists formulate their models without making reference to existing views, redundantly adding complexity to an already difficult problem. In this paper, I present and compare nine neurocognitive models to highlight points of convergence and divergence. Two aspects of consciousness seem especially important: perception of self in time and complexity of self-representations. To this I add frequency of (...) self-focus, amount of self-related information, and accuracy of self-knowledge. Overall, I conclude that many novel concepts (e.g., reflective, primary, core, extended, recursive, and minimal consciousness) are useful in helping us distinguish between delicate variations in consciousness and in clarifying theoretical issues that have been intensely debated in the scientific literature—e.g., consciousness in relation to mirror self-recognition and language.

Traditionally, what we are conscious of in self-consciousness is something non-corporeal. But anti-Cartesian philosophers argue that the self is as much corporeal as it is mental. Because we have the sense of proprioception, a kind of body awareness, we are immediately aware of ourselves as bodies in physical space. In this debate the case histories of patients who have lost their sense of proprioception are clearly relevant. These patients do retain an awareness of themselves as corporeal beings, although they (...) hardly feel their bodies (they have normal sensation in the head, but from the neck downwards only sensations of pain and temperature, and of fatigue and deep touch). They can initiate movements, and with the help of visual feedback learn to control them. It is shown that the traditional view of the self as immaterial is not supported by these cases. But the argument against this view has to be amended. It relies too much on bodily sensations, and misses the importance of active self-movement. (shrink)
By accepting that the formal structure of human language is the key to understanding the uniquity of human culture and consciousness and by further accepting the late appearance of such language amongst the Cro-Magnon, I am free to focus on the causes that led to such an unprecedented threshold crossing. In the complex of causes that led to human being, I look to scholarship in linguistics, mythology, anthropology, paleontology, and to creation myths themselves for an answer. I conclude that (...) prehumans underwent an existential crisis, i.e., the realization of certain mortality, that could be borne only by the discovery-creation of the larger realm of symbolic consciousness once experienced as the sacred (but today we know it as "the world" – as opposed to our immediate natural environment and that of other animals). Thus, although we, the human species, are but one species among innumerable others, we differ in kind, not degree. This quality is our symbolically enabled self-consciousness, the fortress of cultural identity that empowers but also imprisons awareness. (shrink)
The neurobiological systems that mediate the basic emotions are beginning to be understood. They appear to be constituted of genetically coded, but experientially refined executive circuits situated in subcortical areas of the brain which can coordinate the behavioral, physiological and psychological processes that need to be recruited to cope with a variety of primal survival needs (i.e., they signal evolutionary fitness issues). These birthrights allow newborn organisms to begin navigating the complexities of the world and to learn about the values (...) and contingencies of the environment. Some of these systems have been identified and characterized using modern neuroscientific and psychobiological tools. The fundamental emotional systems can now be defined by the functional psychobiological characteristics of the underlying circuitries ? characteristics which help coordinate behavioral, physiological and psychological aspects of emotionality, including the valenced affective feeling states that provide fundamental values for the guidance of behavior. The various emotional circuits are coordinated by different neuropeptides, and the arousal of each system may generate distinct affective/neurodynamic states and imbalances may lead to various psychiatric disorders. The aim of this essay is to discuss the underlying conceptual issues that must be addressed for additional progress in understanding the nature of primary process affective consciousness. (shrink)
Neural Darwinism (ND) is a large scale selectionist theory of brain development and function that has been hypothesized to relate to consciousness. According to ND, consciousness is entailed by reentrant interactions among neuronal populations in the thalamocortical system (the ‘dynamic core’). These interactions, which permit high-order discriminations among possible core states, confer selective advantages on organisms possessing them by linking current perceptual events to a past history of value-dependent learning. Here, we assess the consistency of ND with 16 (...) widely recognized properties of consciousness, both physiological (for example, consciousness is associated with widespread, relatively fast, low amplitude interactions in the thalamocortical system), and phenomenal (for example, consciousness involves the existence of a private flow of events available only to the experiencing subject). While no theory accounts fully for all of these properties at present, we find that ND and its recent extensions fare well. (shrink)
The relationship between mental representation and consciousness is considered. What it means to 'represent', and several types of representation (e.g., analogue, digital, spatial, linguistic, mathematical), are described. Concepts relevant to mental representation in general (e.g., multiple levels of processing, structure/process differences, mapping) and in specific domains (e.g., mental imagery, linguistic/propositional theories, production systems, connectionism, dynamics) are discussed. Similarities (e.g., using distinctions between different forms of representation to predict different forms of consciousness, parallels between digital architectures of the brain (...) and connectionist models) and dissociations (e.g., insensitivity to gaps in subjective experience, explicit memory/implicit memory, automatic processing/controlled processing, blindsight, neglect, prediction/ explanation) of mental representation and consciousness are discussed. It is concluded that representational systems are separable from consciousness systems, and that mental representation appears necessary but not sufficient for consciousness. Considerations for future research on correspondences between representation and consciousness are suggested. (shrink)
The phenomena of human consciousness and subjectivity are explored from the perspective of affect-logic, a comprehensive meta-theory of the interactions between emotion and cognition based mainly on cognitive and social psychology, psychopathology, neurobiology Piaget?s genetic epistemology, psychoanalysis, and evolutionary science. According to this theory, overt or covert affective-cognitive interactions are obligatorily present in all mental activity, seemingly ?neutral? thinking included. Emotions continually exert numerous so-called operator-effects, both linear and nonlinear, on attention, on memory and on comprehensive thought, or logic (...) in a broad sense. They deeply ?affect? also consciousness and subjectivity, as showed by the analysis of four crucially involved phenomena, namely (1) attention, (2) abstraction, (3) language, and (4) the prevailing affective state. The conclusion is that neither consciousness nor subjectiovity can be adequately understood without fully considering their emotional aspects. (shrink)
What is the potential for improvements in the functioning of consciousness? The paper addresses this issue using global workspace theory. According to this model, the prime function of consciousness is to develop novel adaptive responses. Consciousness does this by putting together new combinations of knowledge, skills and other disparate resources that are recruited from throughout the brain. The paper's search for potential improvements in consciousness is aided by studies of a developmental transition that enhances functioning in (...) whichever domain it occurs. This transition involves a shift from the use of procedural (implicit) knowledge to declarative (explicit) knowledge. However, the potential of the transition to enhance functioning has not yet been realised to any extent in relation to consciousness itself. The paper assesses the potential for consciousness to use declarative knowledge to improve its own functioning and to thereby enhance human adaptability. A number of sources (including the practices of religious and contemplative traditions) are drawn on to investigate how this potential might be realised. (shrink)
Causation can be regarded from either an explanatory/epistemic or an ontological viewpoint. From the former, emergent features enter into a host of causal relationships which form a hierarchical structure subject to scientific investigation. From the latter, the paramount issue is whether emergent features provide any novel causal powers, or whether the 'go' of the world is exhausted by the fundamental physical features which underlie emergent phenomena. I argue here that the 'Scientific Picture of the World' (SPW) strongly supports the claim (...) that ontological causation is exhausted in the elementary physical features of the world. A method is developed for distinguishing 'emergent ontological causation' from the epistemological emergent explanatory patterns sanctioned by the SPW, and it is argued that the SPW implies that all emergence is mere epistemological emergence. However, this leads to a paradox when applied to consciousness itself, which turns out to be both epiphenomenal and viewpoint dependent. (shrink)
The first part of this paper defends a 'two-factor' approach to mental representation by moving through various choice-points that map out the main peaks in the landscape of philosophical debate about representation. The choice-points considered are: (1) whether representations are conceptual or non-conceptual; (2) given that mental representation is conceptual, whether conscious perceptual representations are analog or digital; (3) given that the content of a representation is the concept it expresses, whether that content is individuated extensionally or intensionally; (4) whether (...) intensional contents are individuated by external or internal conditions; and (5) given that conceptual content is determined externally, whether the possession conditions for concepts are external or internal. The final part of the paper examines the relationship between representation and consciousness, arguing that any account of mental representation, though necessary for a complete account of consciousness, cannot be sufficient for it.

Human cognition and action are intentional and goal-directed, and explaining how they are controlled is one of the most important tasks of the cognitive sciences. After half a century of benign neglect this task is enjoying increased attention. Unfortunately, however, current theorizing about control in general, and the role of consciousness for/in control in particular, suffers from major conceptual flaws that lead to confusion regarding the following distinctions: (i) automatic and unintentional processes, (ii) exogenous control and disturbance (in a (...) control-theoretical sense) of endogenous control, (iii) conscious control and conscious access to control, and (iv) personal and systems levels of analysis and explanation. Only if these flaws are overcome will a comprehensive understanding of the relationship between consciousness and control emerge. (shrink)
There is a long and storied history of debates over 'realism' that has touched literally every academic discipline. Yet realism- antirealism debates play a relatively minor role in the contemporary study of consciousness. In this paper four basic varieties of realism and antirealism are explored (existential, epistemological, semantic, and ontological) and their potential impact on the study of consciousness is considered. Reasons are offered to explain why there is not more debate over these issues, including a discussion of (...) the powerful influence of externalist versions of physicalist realism. Examples are given of approaches to consciousness studies that challenge contemporary versions of physicalist realism. (shrink)
Some attempts to understand emotion have failed to account for important features of our emotional experience ? notably, the experience of gaining insight when we express our emotions. In this essay I will hold that if we properly understand emotions, then we see that the expression of emotion contributes to the growth of consciousness by providing a process wherein consciousness can recognize and reclaim its inherent wholeness, and thereby overcome fragmentation. Hence, in this essay I will strive to: (...) (1) demonstrate that we do get insight when we express our emotions, (2) offer a suggestion as to why this feature is often overlooked, (3) propose a model for understanding the emotions that helps to explain this holistic feature of emotion, and (4) show how this insight into the nature of emotion contributes to our understanding of the growth of consciousness.

'Consciousness' has been called the 'final frontier' for science, philosophy's 'hard problem', and the greatest mystery in mysticism. It is a central focus in philosophy of mind. Yet confusion abounds about what 'consciousness' means -- even among philosophers, scientists, and mystics who have built careers exploring the mind. Different scholars and different disciplines use the same word to mean very different things. Debates and dialogues on consciousness often run aground because scholars conflate two radically different uses of (...) the term.

While the recent special issue of JCS on machine consciousness (Volume 14, Issue 7) was in preparation, a collection of papers on the same topic, entitled Artificial Consciousness and edited by Antonio Chella and Riccardo Manzotti, was published. 1 The editors of the JCS special issue, Ron Chrisley, Robert Clowes and Steve Torrance, thought it would be a timely and productive move to have authors of papers in their collection review the papers in the Chella and Manzotti book, (...) and include these reviews in the special issue of the journal. Eight of the JCS authors (plus Uziel Awret) volunteered to review one or more of the fifteen papers in Artificial Consciousness; these individual reviews were then collected together with a minimal amount of editing to produce a seamless chapter-by-chapter review of the entire book. Because the number and length of contributions to the JCS issue was greater than expected, the collective review of Artificial Con- sciousness had to be omitted, but here at last it is. Each paper’s review is written by a single author, so any comments made may not reflect the opinions of all nine of the joint authors! (shrink)
What are the states of consciousness in themselves, those pulses of mentality that follow one upon another in tight succession and constitute the stream of consciousness? William James conceives of each of them as being, typically, a complex unitary awareness that instantiates many features and takes a multiplicity of objects. In contrast, Brian O?Shaughnessy claims that the basic durational component of the stream of consciousness is the attention, which he understands to be something like a psychic space (...) that is simultaneously occupied by several experiences. Whereas, according to the first conception, emotion is a feature of a temporal segment of the stream of consciousness and colors through and through each consciousness state that instantiates it, the second conception considers an emotion to be a distinct one of a system of simultaneous experiences that interact with each other, for example, limiting each other?s number and intensity. Among other matters discussed is the two theorists? mutually contrasting conception of how the non-inferential awareness which we have of our states of consciousness is accomplished. (shrink)
Abstract: Many astrologers attribute a successful birth-chart reading to what they call intuition or psychic ability,where the birth chart acts like a crystal ball. As in shamanism,they relate consciousness to a transcendent reality that,if true, might require are-assessment of present biological theories of consciousness.In Western countries roughly 1 person in 10,000 is practising or seriously studying astrology, so their total number is substantial. Many tests of astrologers have been made since the 1950s but only recently has a coherent (...) review been possible. A large-scale test of persons born less than five minutes apart found no hint of the similarities predicted by astrology. Meta-analysis of more than forty controlled studies suggests that astrologers are unable to perform significantly better than chance even on the more basic tasks such as predicting extraversion. More specifically,astrologers who claim to use psychic ability perform no better than those who do not. The possibility that astrology might be relevant to consciousness and psi is not denied, but such influences, if they exist in astrology,would seem to be very weak or very rare. -/- . (shrink)
We perceive colour, shape, sound and touch 'bound together' in a single experience. The following arguments about this binding phenomenon are raised: (1) The individual signals passing from neurone to neurone are not bound together, whether as elements of information or physically. (2) Within a single cell, binding in terms of bringing together of information is potentially feasible. A physical substrate may also be available. (3) It is therefore proposed that a bound conscious experience must be a property of an (...) individual cell, not of a group of cells. Since it is unlikely that one specific neurone is conscious, it is suggested that every neurone has a version of our consciousness, or at least some form of sentience. However absurd this may seem it appears to be consistent with the available evidence; arguably the only explanation that is. It probably does not alter the way we should expect to experience the world, but may help to explain the ways we seem to differ from digital computers and some of the paradoxes seen in mental illness. It predicts non-digital features of intracellular computation, for which there is already evidence, and which should be open to further experimental exploration. The arguments given may well prove flawed or the conclusion biologically or physically untenable, but the idea is raised for discussion not least because a formal demonstration that it is invalid may help to identify more fruitful avenues.

What are the folk-conceptual connections between free will and consciousness? In this paper I present results which indicate that consciousness plays central roles in folk conceptions of free will. When conscious states cause behavior, people tend to judge that the agent acted freely. And when unconscious states cause behavior, people tend to judge that the agent did not act freely. Further, these studies contribute to recent experimental work on folk philosophical affiliation, which analyzes folk responses to determine whether (...) folk views are consistent with the view that free will and determinism are incompatible (incompatibilism) or with the opposite view (compatibilism). Conscious causation of behavior tends to elicit pro-free will judgments, even when the causation takes place deterministically. Thus, when controlling for consciousness, many folk seem to be compatibilists. However, participants who disagree with the deterministic or cognitive scientific descriptions given of human behavior tend to give incompatibilist responses. (shrink)
b>. One major problem many hypotheses regarding the neural correlate of consciousness (NCC) face is what we might call “the why question”: _why _would this particular neural feature, rather than another, correlate with consciousness? The purpose of the present paper is to develop an NCC hypothesis that answers this question. The proposed hypothesis is inspired by the Cross-Order Integration (COI) theory of consciousness, according to which consciousness arises from the functional integration of a first-order representation of (...) an external stimulus and a second-order representation of that first-order representation. The proposal comes in two steps. The first step concerns the “general shape” of the NCC and can be directly derived from COI theory. The second step is a concrete hypothesis that can be arrived at by combining the general shape with empirical considerations. (shrink)
What is this thing we each call “I” and consider the eye of consciousness, that which beholds objects in the world and objects in our minds? This inner perceiver seems to be the same I who calls forth memories or images at will, the I who feels and determines whether to act on those feelings or suppress them, as well as the I who worries and makes plans and attempts to avoid those worries and act on those plans. Am (...) I the subject, thus the source, of my awareness, just as you are the subject and source of your awareness? If this is the case, it is likely impossible to be conscious without the self (yours or mine), the eye of consciousness, and it must certainly not be desirable, for such a consciousness would have no focal point, no self-that-is-conscious to guide it, so it would be cast adrift on a wide and wild sea like a boat that has broken from its anchor. Without self-enclosure, “We shall go mad no doubt and die that way,” as Robert Graves (1927/1966) expressed it in "The Cool Web". (shrink)
The author claims that concept possession is not only necessary but also sufficient for self-consciousness, where self-consciousness is understood as the awareness of oneself as a self. Further, he links concept possession to intelligent behavior. His ultimate aim is to provide a framework for the study of self-consciousness in infants and non-human animals. I argue that the claim that all concepts are necessarily related to the self-concept remains unconvincing and suggest that what might be at issue here (...) are not so much conceptual but rather metacognitive abilities.

Replication or even modelling of consciousness in machines requires some clarifications and refinements of our concept of consciousness. Design of, construction of, and interaction with artificial systems can itself assist in this conceptual development. We start with the tentative hypothesis that although the word “consciousness” has no well-defined meaning, it is used to refer to aspects of human and animal informationprocessing. We then argue that we can enhance our understanding of what these aspects might be by designing (...) and building virtual-machine architectures capturing various features of consciousness. This activity may in turn nurture the development of our concepts of consciousness, showing how an analysis based on information-processing virtual machines answers old philosophical puzzles as well enriching empirical theories. This process of developing and testing ideas by developing and testing designs leads to gradual refinement of many of our pre-theoretical concepts of mind, showing how they can be construed as implicitly “architecture-based” concepts. Understanding how humanlike robots with appropriate architectures are likely to feel puzzled about qualia may help us resolve those puzzles. The concept of “qualia” turns out to be an “architecture-based” concept, while individual qualia concepts are “architecture-driven”. (shrink)
A frequent criticism of the neuroscientific approach to consciousness is that its theories describe only 'correlates' or 'analogues' of consciousness, and so fail to address the nature of consciousness itself. Despite its apparent logical simplicity, this criticism in fact relies on some substantive assumptions about the nature and evolution of scientific explanations. In particular, it is usually assumed that, in expressing correlations, neural correlate of consciousness (NCC) theories must fail to capture the causal structure relating brain (...) and mind. Drawing on work in the history and philosophy of science, I argue that this assumption - along with the related claim that even a correct NCC theory would fail to explain consciousness - is grounded in an inadequate conception of the way in which scientific explanations develop. Examination of parallel developments in 20th century biology reveals that, under the right circumstances, seemingly crude correspondences can play an essential role in scientific discovery and can sometimes become central to our everyday understanding of the phenomena in question. A proper understanding of this process clarifies the value of NCC theories and sheds light on the standards by which they should be evaluated. In closing, I describe two specific criteria for evaluating NCC proposals: intertheoretic bridge potential and detailed mapping. (shrink)
A stream of conscious experience is extremely contextual; it is impacted by sensory stimuli, drives and emotions, and the web of associations that link, directly or indirectly, the subject of experience to other elements of the individual's worldview. The contextuality of one's conscious experience both enhances and constrains the contextuality of one's behavior. Since we cannot know first-hand the conscious experience of another, it is by way of behavioral contextuality that we make judgements about whether or not, and to what (...) extent, a system is conscious. Thus we believe that a deep understanding of contextuality is vital to the study of consciousness. Methods have been developed for handling contextuality in the microworld of quantum particles. Our goal has been to investigate the extent to which these methods can be used to analyze contextuality in conscious experience. (shrink)
I should like to convey to you some doubts which have occurred to me on the subject of the notion of consciousness that prevails in all our treatises on psychology.
from non-conscious components by positing that consciousness is a universal primitive. For example, the double aspect theory of information holds that infor- mation has a phenomenal aspect. How then do you get from phenomenal infor- mation to human consciousness? This paper proposes that an entity is conscious to the extent it amplifies information, first by trapping and integrating it through closure, and second by maintaining dynamics at the edge of chaos through simul- taneous processes of divergence and convergence. (...) The origin of life through autocatalytic closure, and the origin of an interconnected worldview through conceptual closure, induced phase transitions in the degree to which informa- tion, and thus consciousness, is locally amplified. Divergence and convergence of cognitive information may involve phenomena observed in light e.g. focusing, interference, and resonance. By making information flow inward- biased, clo- sure shields us from external consciousness; thus the paucity of consciousness may be an illusion. (shrink)
If the universe is a machine, consciousness is not possible. If the universe is more than a machine, then physics is incomplete. Since we are both part of the universe and conscious, physics must be incomplete and the understanding required to construct conscious mechanisms must be sought through the advancement of physics not the continued application of inadequate concepts. In this paper I will show that an impediment to this advancement is the confusion arising through the use of terms (...) such as 'physical reality' to refer to an absolute a priori Kantian 'Ding an Sich' when they should both be recognized as referring to data structures holding the knowledge upon which we act and nothing more. Once this confusion has been clarified, I will go on to suggest that the cycle of activity updating physical reality becomes a candidate for a conscious process. I will show how implementing algorithms in modern computers can mimic this process but if actual consciousness is to be achieved the update activity must correspond to a cycle in time. Such cycles have been identified with Whitehead's 'actual occasions' and thus I will argue that fundamental events should replace fundamental particles as the building blocks of the universe if consciousness is to be explained.

Preface/Introduction: The question under discussion is metaphysical and truly elemental. It emerges in two aspects — how did we come to be conscious of our own existence, and, as a deeper corollary, do existence and awareness necessitate each other? I am bold enough to explore these questions and I invite you to come along; I make no claim to have discovered absolute answers. However, I do believe I have created here a compelling interpretation. You’ll have to judge for yourself. -/- (...) What follows is the presentation of three essays I have worked on over the past several years seeing publication for the first time. “Hollows of Experience” was written first as an invited chapter for a collection on the ontology of consciousness. However, when cuts became necessary, my chapter got the knife. Its length has prohibited it from publication in any print journal. “Myth and Mind” was written next as a journal article, but as my involvement with it grew so did its length, so it has also idled on my websty awaiting its call. “From Panexperientialism to Conscious Experience” was written most recently, but it is the only one to have been available to the public elsewhere than my own website. Under the name, “The Continuum of Experience”, it was Target Article #95 on the recently closed Karl Jaspers Forum (for discussion purposes only). -/- I have put them in a different sequence here, for reasons of logical sense. Up first, “Panexperientialism” deals with an idea difficult for many to accept, namely that conscious experience is a particular mode of symbolically reflected experience that is largely unique to our species. However, I aver that experienced sensation in itself (as found, for example, in autonomic sensory response systems) goes “all the way down” into nature, and thus the title, panexperientialism. -/- Understanding this idea is helpful to dealing with the focus on language in Part I of “Hollows”, next, since here speech and general symbolic interaction in general are found to be the catalysts for the creation of our consciously experienced world (our “lived reality”). In Part II, however, I explore how experienced sensations must be coeval with existence, and, with even greater temerity, how all this sensational existence might have arisen within some literally inconceivable background of awareness-in-itself that yet has a dynamism that occasionally breaks into existence as experiential events and entities. (The latter may sound wacky, but physicists and cosmologists are themselves attempting to come to terms with that which seethes with vast potential energy in what they refer to as the quantum vacuum.) -/- “Myth and Mind” was put third since it deals with a major lacuna in “Hollows” — that presumed prehistoric period when members of our species made the painful crossing of the symbolic threshold into the beginnings of cultural consciousness. Speech plays a central role here, too, but I look more at narrative structures from the dawn of self-awareness when ritual and myth became vital to human survival. Why would fantastic stories and bizarre rituals be necessary? I speculate that growing foresight led to the unavoidable realization of certain mortality, from which, in turn, emerged the secondary realization that we were now alive. In contrast to our yet-to-come death, we have life here and now, and by ritually identifying with a symbolically expanded mythic, i.e., sacred, reality, we may continue to live on after bodily death, just as our ancestors and loved ones must also do. Language and mythmaking are necessary to avoid mortal despair and they remain at the core of human consciousness. -/- As Ernst Cassirer (1944) has noted, language and myth are “twin creatures”, both metaphoric webs over a reality we can never wholly comprehend. We live in the symbolic and construct our works of imagination and wars of conquest to make life meaningful, to feel immortal, and to sense that we ourselves participate in a reality greater than ourselves. No doubt we do, but this does not mean our culturally constructed self-identities survive the death of our bodies, and it does not imply that our symbolic concepts can ever indicate the ultimate truth. We simply must symbolize an extended reality that was sacred to our ancestors: “Is it not our way, as illusory as it may be, to force continuance on our world and our life in the face of their inevitable ending? Are we not compelled to extend those imaginary horizons as far as we can despite the terror and the sometime joy their extension incites? Is their closure not a form of death?” (Crapanzano, p. 210) -/- Of course, this leaves me in the uncomfortable position of being forced to admit that this venture of mine must inevitably be another attempt at meaningful mythmaking. But what else could it be? This is certainly not a scientific proof though it is indeed an academically rigorous exploration. (Just try to count the citations!) I hope the reader will judge my thesis on the basis of its coherence, the sense of meaning it evokes, my intellectual responsibility, and, finally, the engagement it inspires. If you have read my expositions and found yourself immersed in the timeless questions I here call forth, I would call these writings successful (even if you violently disagree with my answers). -/- I am very grateful to Huping Hu for granting me this special issue of JCER in which to present my ideas in some detail. He has patiently dealt with my exuberant approach and allowed the many changes I kept coming up with right until the final publication date. I also wish to thank the many potential commentators who politely replied to my invitation, and, even more, I thank those who made time to write actual commentaries. -/- References -/- Cassirer, E.

Setting aside the problems of recognising consciousness in a machine, this article considers what would be needed for a machine to have human-like conscious- ness. Human-like consciousness is an illusion; that is, it exists but is not what it appears to be. The illusion that we are a conscious self having a stream of experi- ences is constructed when memes compete for replication by human hosts. Some memes survive by being promoted as personal beliefs, desires, opinions and pos- (...) sessions, leading to the formation of a memeplex (or selfplex). Any machine capa- ble of imitation would acquire this type of illusion and think it was conscious. Robots that imitated humans would acquire an illusion of self and consciousness just as we do. Robots that imitated each other would develop their own separate languages, cultures and illusions of self. Distributed seflplexes in large networks of machines are also possible. Unanswered questions include what remains of consciousness without memes, and whether artificial meme machines can ever transcend the illusion of self consciousness. (shrink)
Charles Darwin is generally credited with having formulated the first systematic attempt to explain the evolutionary origins and function of the expression of emotions in animals and humans. His ingenious theory, however, was burdened with popular misconceptions about human phylogenetic heritage and bore the philosophical and theoretical deficiencies of the brain science of his era that his successors strove to overcome. In their attempts to rectify Darwin?s errors, William James, James Mark Baldwin and John Dewey each made important contributions to (...) a theory of emotion, which attempted to put it on a more secure philosophical and scientific footing. My contention is that Dewey and his collaborator, infant experimentalist Myrtle McGraw, succeeded where their contemporaries failed. They pointed the way out of the morass of recapitulationism, and showed how a developmental theory of consciousness, mind and emotion could be formulated that avoided the epistemological and ontological pitfalls of Darwin?s theory. Drawing on an extensive body of research from contemporary experimental studies of infant development, this essay attempts to put the questions raised by these historical figures about the structure, function and value of emotions in a theoretical framework. A developmental theory is proposed about the complex, interacting neurobiological and neurobehavioral factors that contribute to human emotional development. This theory identifies the possible relationships among emotions, consciousness and mind and how their co-development influences the capacity of young children to form moral judgments. (shrink)
There is quite a bit of disagreement in cognitive science regarding the role that consciousness and control play in explanations of how people do what they do. The purpose of the present paper is to do the following: (1) examine the theoretical choice points that have lead theorists to conflicting positions, (2) examine the philosophical and empirical problems different theories encounter as they address the issue of conscious agency, and (3) provide an integrative framework (Wild Systems Theory) that addresses (...) these problems and potentially naturalizes conscious agency. It does so by grounding conscious and control in the notion of self-sustaining energy-transformation systems (i.e., living systems), versus computational or self- organizing systems, as is the case in information processing theory and dynamical systems theory, respectively. Given its assertion that content (and consciousness) emerges in self-sustaining systems, Wild Systems Theory may also provide a sound theoretical basis for a science of consciousness in general.

In this short paper I will introduce an idea which, I will argue, presents a fundamental additional challenge to the machine consciousness community. The idea takes the questions surrounding phenomenology, qualia and phenomenality one step further into the realm of intersubjectivity but with a twist, and the twist is this: that an agent’s intersubjective experience is deeply felt and necessarily co-affective; it is enkinaesthetic, and only through enkinaesthetic awareness can we establish the affective enfolding which enables first the perturbation, (...) and then the balance and counter-balance, the attunement and co-ordination of whole-body interaction through reciprocal adaptation.

How are the states of consciousness intrinsically so that they all qualify as ?feelings? in William James?s generic sense? Only a small, propaedeutic part of what is required to address the intrinsic nature of such states can be accomplished here. I restrict my topic mainly to a certain characteristic that belongs to each of those pulses of mentality that successively make up James?s stream of consciousness. Certain statements of James?s are intended to pick out the variable ?width? belonging (...) to a stream of consciousness as it flows. Attention to this proposed property brings me to a discussion of (a) the unitary character of each of the states of consciousness however complex they may frequently be and (b) how to conceive of their complexity without recourse to a misleading spatial metaphor.

In the latter part of this two-article sequence, the concept of emotion as reorganization of the organism-environment system is developed further in relation to consciousness, subjective experience and brain activity. It is argued that conscious emotions have their origin in reorganizational changes in primitive co-operative organizations, in which they get a more local character with the advent of personal consciousness and individuality, being expressed in conscious emotions. However, the conscious emotion is not confined to the individual only, but (...) it gets its content and the emotional quale in the social context, and in relation to the norms of the given culture. Emotion is fundamentally the process of ascription of meaning to the parts of the world which are relevant in the achievement of results of behavior. Although emotions may be studied as reorganizational processes in the organism-environment system with the help of physiological recordings and behavioral observations, it is argued — in contrast to the mainstream cognitive science — that emotions cannot be localized in the brain, although the brain is important in their generation as a part of the organism-environment system. It is suggested that the parts of the brain most closely related to emotional expression contain neurons subserving functional systems which are formed in early development, and which are therefore most intimately related to reorganizational processes in the organism-environment system.

This is an introductory essay from The Interplay between Consciousness and Concepts, which I guest edited as a special double issue of the Journal of Consciousness Studies (vol. 14, Sept/Oct). It is also sold separately as a book by Imprint Academic.
The Latin conscius does not translate anything like mind or consciousness. Only in the mid-nineteenth century do we find the first attempts to study consciousness as its own discipline. Wundt, James, and Freud disagreed about how to approach the science of consciousness, although agreeing that psychology was a 'science of consciousness' that takes lived biological experience as its object. The behaviorists vetoed this idea. By the 1950s, for cognitive science, mind (conscious and unconscious) was considered analogous (...) to computer software. Recently, the science of consciousness has returned as Consciousness Studies, a new interdisciplinary synthesis of neuroscience, psychology, philosophy, and cultural anthropology. But what is new in this renaissance of the science of consciousness? New first, second and third person approaches all propose to take consciousness itself as a variable. This approach is as controversial as the nineteenth-century science of consciousness--controversy perhaps inherent to any science of consciousness. (shrink)
The value of resting electroencephalogram (EEG) in revealing neural constitutes of consciousness (NCC) was examined. We quantified the dynamic repertoire, duration and oscillatory type of EEG microstates in eyes-closed rest in relation to the degree of expression of clinical self-consciousness. For NCC a model was suggested that contrasted normal, severely disturbed state of consciousness and state without consciousness. Patients with disorders of consciousness were used. Results suggested that the repertoire, duration and oscillatory type of EEG (...) microstates in resting condition quantitatively related to the level of consciousness expression in brain-damaged patients and healthy-conscious subjects. Specifically, results demonstrated that (a) decreased number of EEG microstate types was associated with altered states of consciousness, (b) unawareness was associated with the lack of diversity in EEG alpha-rhythmic microstates, and (c) the probability for the occurrence and duration of delta-, theta- and slow-alpha-rhythmic microstates were associated with unawareness, whereas the probability for the occurrence and duration of fast-alpha-rhythmic microstates were associated with consciousness. In conclusion, resting EEG has a potential value in revealing NCC. This work may have implications for clinical care and medical–legal decisions in patients with disorders of consciousness. (shrink)
Contemporary neuroscientific theories of consciousness are typically based on the study of vision and have neglected olfaction. Several of these (e.g. Global Workspace Theories, the Information Integration theory, and the various theories offered by Crick and Koch) claim that a thalamic relay is necessary for consciousness. Studies on olfaction and the olfactory system's anatomical structure show this claim to be incorrect, thus showing these theories to be either false or inadequate as general and comprehensive accounts of consciousness. (...) Attempts to rescue these theories by claiming that there is a structure in the olfactory system that is functionally equivalent to the thalamus in the visual system, such as the olfactory bulb or the olfactory cortex, are also shown to fail. If we wish to understand consciousness, we have to wake up and smell it. (shrink)
Treating consciousness as awareness or attention greatly underestimates it, ignoring the temporary levels of organization associated with higher intellectual function (syntax, planning, logic, music). The tasks that require consciousness tend to be the ones that demand a lot of resources. Routine tasks can be handled on the back burner but dealing with ambiguity, groping around offline, generating creative choices, and performing precision movements may temporarily require substantial allocations of neocortex. Here I will attempt to clarify the appropriate levels (...) of explanation (ranging from quantum aspects to association cortex dynamics) and then propose a specific mechanism (consciousness as the current winner of Darwinian copying competitions in cerebral cortex) that seems capable of encompassing the higher intellectual function aspects of consciousness as well as some of the attentional aspects. It includes features such as a coding space appropriate for analogies and a supervisory Darwinian process that can bias the operation of other Darwinian processes. (shrink)
The truly philosophical issue in machine conscioiusness is whether machines can have 'hard consciounsess' (like in Chalmers' hard problem of consciousness). Criteria for hard consciousness are higher than for phenomenal consciousness, since the latter incorporates first-person functional consciousness.
High figure-ground contrast usually results in more positive evaluations of visual stimuli. This may either reflect that high figure-ground contrast per se is a desirable attribute or that this attribute facilitates fluent processing. In the latter case, the influence of high figure-ground contrast should be most pronounced under short exposure times, that is, under conditions where the facilitative influence on perceptual fluency is most pronounced. Supporting this hypothesis, ratings of the prettiness of visual stimuli increased with figure-ground contrast under short (...) exposure times (.3, 1, and 3 seconds, respectively). This positive influence of figure-ground contrast was eliminated under an exposure time of 10 seconds. We conclude that stimuli with high figure-ground contrast are more appealing because they are easier to process, not because high figure-ground contrast per se is a desirable attribute. We discuss this finding in the context of William James? notion that the fringe of consciousness includes vague contextual feelings at the periphery of the focus of attention and suggest that perceptual fluency is one of these feelings.

According to one influential view, consciousness has an awareness– content structure: any experience consists of the awareness of some content. I focus on one version of this dualism, and argue that it should be rejected. My principal argument is directed at the status of the supposed contents of aware- ness; I argue that neither of the principal options is tenable, albeit for different reasons. Although the doctrine in question may seem to be supported by the find- ings of researchers (...) in meditative traditions, I question whether this evidence sup- ports the dualism that is my target here. To conclude, I introduce an innocuous mode of pure awareness. (shrink)
I make three points about Searle’s philosophical work on consciousness and intentionality. First, I comment on Searle’s presentation and paper “The Problems of Consciousness.” I show that one of Searle’s philosophical claims about the relation between consciousness and intentionality appears to conflict with a demand he makes on acceptable empirical theories of the brain. Second, I argue that closer attention to the difference between conceptual connections and empirical connections corrects and improves Searle’s response to the so-called “Logical (...) Connections” argument, the argument that claims that mental states cannot be causes, since they are conceptually connected with actions. Third, I give a formulation of his Chinese Room argument that avoids some tempting responses. (shrink)
My target article (henceforth referred to as TA) presents evidence for causal interactions between consciousness and brain and some standard ways of accounting for this evidence in clinical practice and neuropsychological theory. I also point out some of the problems of understanding such causal interactions that are not addressed by standard explanations. Most of the residual problems have to do with how to cross the “explanatory gap” from consciousness to brain. I then list some of the reasons why (...) the route across this gap suggested by physicalism won't work, in spite of its current popularity in consciousness studies. My own suggested route across the explanatory gap is more subterranean, where consciousness and brain can be seen to be dual aspects of a unifying, psychophysical mind. Some of the steps on this deeper route still have to be filled in by empirical research. But (as far as I can judge) there are no gaps that cannot be filled—just a different way of understanding consciousness, mind, brain and their causal interaction, with some interesting consequences for our understanding of free will. The commentaries on TA examined many aspects of my thesis viewed from both Western and Eastern perspectives. This reply focuses on how dual-aspect monism compares with currently popular alternatives such as “nonreductive physicalism”, clarifies my own approach, and reconsiders how well this addresses the “hard” problems of consciousness. We re-examine how conscious experiences relate to their physical/functional correlates and whether useful analogies can be drawn with other, physical relationships that appear to have dual-aspects. We also examine some fundamental differences between Western and Eastern thought about whether the existence of the physical world or the existence of consciousness can be taken for granted (with consequential differences about which of these is “hard” to understand). I then suggest a form of dual-aspect Reflexive Monism that might provide a path between these ancient intellectual traditions that is consistent with science and with common sense. (shrink)
Participants were required to switch among randomly ordered tasks, and instructional cues were used to indicate which task to execute. In Experiments 1 and 2, the participants indicated their readiness for the task switch before they received the target stimulus; thus, each trial was associated with two primary dependent measures: (1) readiness time and (2) target reaction time. Slow readiness responses and instructions emphasizing high readiness were paradoxically accompanied by slow target reaction time. Moreover, the effect of task switching on (...) readiness time was an order of magnitude smaller then the (objectively estimated) duration required for task preparation (Experiment 3). The results strongly suggest that participants have little conscious awareness of their preparedness and challenge commonly accepted assumptions concerning the role of consciousness in cognitive control.

This paper explores some connections between the philosophically central topic of intersubjectivity highlighted in John Ziman's article and the notion of collective consciousness, which has received very little formal attention in mainstream philosophy. The deconstruction of the Cartesian model of isolated spheres of consciousness which the intersubjective viewpoint brings about is supported by considerations from Kant's critical account of transcendental psychology. The phenomenon of empathy, an essential component in the achievement of intersubjective consensus, is related to the possibility (...) of shared experiences, i.e. of two or more individuals participating in the same conscious experience. The use of mental concept-words applied to collectives of persons is interpreted as more than a mere metaphor; this interpretation is supported by comparison with complex collective behaviours in other social species. It is necessary to say that this paper very much represents work in progress-- other commitments have prevented the author from supporting many of the points made with references or further analysis at this stage, and it is hoped merely that this exploratory essay will provide useful ideas for further research.

We should eventually understand how exactly first person phenomenal consciousness is generated. When we do, we should be able to enginner one for robots. This is the engineering thesis in machine consciousness.
Possible systemic effects of general anesthetic agents on neural information processing are discussed in the context of the thalamocortical suppression hypothesis presented by Drs. Alkire, Haier, and Fallon (this issue) in their PET study of the anesthetized state. Accounts of the neural requisites of consciousness fall into two broad categories. Neuronal-specificity theories postulate that activity in particular neural populations is sufficient for conscious awareness, while process-coherence theories postulate that particular organizations of neural activity are sufficient. Accounts of anesthetic narcosis, (...) on the other hand, explain losses of consciousness in terms of neural signal-suppressions, transmission blocks, and the disruptions of signal interpretation. While signal-suppression may account for the actions of some anesthetic agents, the existence of anesthetics, such as choralose, that cause both loss of consciousness and elevated discharge rates, is problematic for a general theory of narcosis that is based purely on signal suppression and transmission-block. However, anesthetic agents also alter relative firing rates and temporal discharge patterns that may disrupt the coherence of neural signals and the functioning of the neural networks that interpret them. It is difficult at present, solely on the basis of regional brain metabolic rates, to test process-coherence hypotheses regarding organizational requisites for conscious awareness. While these pioneering PET studies have great merit as panoramic windows of mind-brain correlates, wider ranges of theory and empirical evidence need to be brought into the formulation of truly comprehensive theories of consciousness and anesthesia.

Dienes and Seth (2010) conclude that confidence ratings and post-decision wagering are two comparable and recommendable measures of conscious experience. In a recently submitted paper, we have however found that both methods are problematic and seem less suited to measure consciousness than a direct introspective measure. Here, we discuss the methodology and conclusions put forward by Dienes and Seth, and why we think the two experiments end up with so different recommendations.
There are now various approaches to understand where and how in the brain consciousness arises from neural activity, none of which is universally accepted. Difficulties among these approaches are reviewed, and a missing ingredient is proposed here to help adjudicate between them, that of ''perspectivalness.'' In addition to a suitable temporal duration and information content of the relevant bound brain activity, this extra component is posited as being a further important ingredient for the creation of consciousness from neural (...) activity. It guides the development of what is termed the ''Central Representation,'' which is supposed to be present in all mammals and extended in humans to support self-consciousness as well as phenomenal consciousness. Experimental evidence and a theoretical framework for the existence of the central representation are presented, which relates the extra component to specific buffer working memory sites in the inferior parietal lobes, acting as attentional coordinators on the spatial maps making up the central representation. The article closes with a discussion of various open questions. (shrink)
In the physical sciences a rigorous theory is a hierarchy of descriptions in which causal relationships between many general types of entity at a phenomenological level can be derived from causal relationships between smaller numbers of simpler entities at more detailed levels. The hierarchy of descriptions resembles the modular hierarchy created in electronic systems in order to be able to modify a complex functionality without excessive side effects. Such a hierarchy would make it possible to establish a rigorous scientific theory (...) of consciousness. The causal relationships implicit in definitions of access consciousness and phe- nomenal consciousness are made explicit, and the corresponding causal relationships at the more detailed levels of perception, memory, and skill learning described. Extension of these causal relationships to physiological and neural levels is discussed. The general capability of a range of current consciousness models to support a modular hierarchy which could generate these causal relationships is reviewed, and the specific capabilities of two models with good general capabilities are compared in some detail.

Durgin's (2002) commentary on our article provides us with an opportunity to look more closely at the relationship between information processing and consciousness. In our article we contrasted the information processing approach to interpreting our data, with our own 'scientific' approach to consciousness. However, we should point out that, on our view, information processing as a methodology is not by itself in conflict with the scientific study of consciousness - indeed, we have adopted this very methodology in (...) our experiments, which we purport to use to investigate consciousness. Furthermore, Durgin's own review of the history of research on metacontrast (Lachter & Durgin, 1999) shows that some researchers investigating metacontrast also thought that they were in the business of evaluating the role of consciousness in accounting for their effects. Yet, there is no doubt that metacontrast research is a paradigm case of research generated from an information processing perspective. So, prima facie, investigating consciousness and using information processing methodology are compatible. (shrink)
Abstract: Nietzsche’s famously wrote that “consciousness is a surface” (EH, Why I am so clever, 9: 97). The aim of this paper is to make sense of this quite puzzling contention—Superficiality, for short. In doing this, I shall focus on two further claims—both to be found in Gay Science 354—which I take to substantiate Nietzsche’s endorsement of Superficiality. The first claim is that consciousness is superfluous—which I call the “superfluousness claim” (SC). The second claim is that consciousness (...) is the source of some deep falsification—which I call the “falsification claim” (FC). I shall start by considering Nietzsche’s notion of consciousness. Here, I shall argue that the kind of consciousness he is concerned with is in fact self-consciousness and that he put forward a higher-order theory of it. Then, I shall address the two claims. Regarding (FC), my proposal will be that, according to Nietzsche, the content of (self-)conscious mental states is falsified in virtue of its being articulated propositionally. Regarding (SC), I shall claim that it is best read as a weak version of epiphenomenalism about conscious causation. In addressing both points, I shall discuss in particular the influential reading of Nietzsche’s theory of consciousness offered by Katsafanas (2005). (shrink)
Consciousness is seen as a difficult “binding” problem. Binding, a process where different sensations evoked by an item are associated in the nervous system, can be viewed as a process similar to associative learning. Several reports that consciousness is associated with some form of memory imply that different forms of memories have a common feature contributing to consciousness. Based on a proposed synaptic mechanism capable of explaining different forms of memory, we developed a framework for consciousness. (...) It is based on the formation of semblance of sensory stimulus from (1) synaptic semblances when excitatory postsynaptic potentials arrive at functionally LINKed postsynaptic membranes, and (2) network semblances when these potentials summate to elicit action potential initiating activity in a network of neurons. It is then possible to derive a framework for consciousness as a multi-dimensional semblance. According to this framework, a continuum of semblances formed from background sensory stimuli and oscillating neuronal activities serve to maintain consciousness. Feasibility of this framework to explain various physiological and pathological states of consciousness, its subjective nature and qualia is examined. (shrink)
When I look at the scale of the apparatus I know what it reads. Those absurdly delicate, hopelessly inaccessible, global correlations obviously vanish when they connect up with me. Whether this is because consciousness is beyond the range of phenomena that quantum mechanics is capable of dealing with, or because it has infinitely many degrees of freedom or special super selection rules of its own, I would not presume to guess. But this is a puzzle about consciousness that (...) should not get mixed up with efforts to understand quantum mechanics as a theory of subsystem correlations in the nonconscious world.

For more than 100 years, anthropologists have collected ethnographic research among communities who assert that the spirits, animal allies, and other entities of the unseen world are “really real,” yet we have historically contextualized this information under the umbrella of cultural relativism rather than taking the veracity of these claims seriously. In the last decade, some anthropologists claim that our discipline has finally undergone an ontological turn, which opens a door for anthropologists to finally take claims of nonhuman sentience seriously (...) under the umbrella of ontological, rather than cultural, relativism. This paper takes issue with ontological relativism as just one more frame for explaining away the stories of other-than-human consciousness that ethnographers report and suggests that there is an urgent need to consider the relevance, rather than the relativism, of other-than-human consciousness. It looks to Michael Harner's work as a welcome alternative to ontological relativism and encourages opening our minds to a reconsideration of what is “really real.”. (shrink)
Symbolic healing, that is, responding to meaningful experiences in positive ways, can facilitate human healing. This process partly engages consciousness and partly evades consciousness completely (sometimes it partakes of both simultaneously). This paper, presented as the Society for the Anthropology of Consciousness Distinguished Lecture at the 2011 AAA meeting in Montreal, reviews recent research on what is ordinarily (and unfortunately) called the “placebo effect.” The author makes the argument that language use should change, and the relevant portions (...) of what is often called the placebo effect should be referred to as the “meaning response.”.

It is very curious that C.G. Jung has had so little influence upon the anthropology of consciousness. In this paper, the reasons for this oversight are given. The archetypal psychology of Jung is summarized and shown to be more complex and useful than extreme constructivist accounts would acknowledge. Jung's thinking about consciousness fits very well with a modern neuroscience view of the psyche and acts as a corrective to relativist notions of consciousness and its relation to the (...) self.

Recent experiments have shown that the amplitudes of cortical gamma band oscillatory activities that occur during anesthesia are often greater than amplitudes of similar activities that occur without anesthesia. This result is apparently at odds with the hypothesis that synchronized oscillatory activities constitute the neural correlate of consciousness. We argue that while synchronization and oscillatory patterning are necessary conditions for consciousness, they are not sufficient. Based on the results of a binocular rivalry study of Fries et al. (1997), (...) we propose that the degrees of oscillatory strength and synchronization of neuronal activities determine the degree of awareness those activities produce. On the other hand, the overal firing rates of neurons in cortical sensory areas are not correlated with the degree of awareness the activities of those neurons produce. The results of the experiment of Fries et al. (1997) appear to conflict with the results of another binocular rivalry experiment, in which monkeys were trained to pull a lever in order to report which stimulus object was being perceived (Leopold & Logothetis, 1996). In the latter experiment, it was demonstrated that the firing rates of neurons in striate cortex did not change during perceptual alterations, while 90% of neurons in inferior and superior temporal cortices changed their firing rate when the perceived image changed. This result led to the conclusion that activities in temporal cortex are correlated with visual awareness, but those in striate cortex are not. We argue that activities in temporal cortex contribute little, if anything, to perceptual awareness, and that their primary function is computational. Thus the correlation between the firing rates of neurons in these areas and the responses of the monkeys is due to the recognition of a particular stimulus object, which in turn is due to the computations made there.

Anthropologists working on altered states of consciousness (ASC) have suggested that we should do away with psychologizing concepts and use people's own terms for these experiences. With material drawn from the Orang Sakai of Sumatra this paper shows that practitioners who utilize ASC do recognize the alteration of states of awareness as preconditions for numinous interactions. Also critically discussed is the term ASC.
The most central metaphysical question about phenomenal consciousness is that of what constitutes phenomenal consciousness, whereas the most central epistemic question about consciousness is that of whether science can eventually provide an explanation of phenomenal consciousness. Many philosophers have argued that science doesn't have the means to answer the question of what consciousness is (the explanatory gap) but that consciousness nonetheless is fully determined by the physical facts underlying it (no metaphysical gap). Others have (...) argued that the explanatory gap in the sciences entails a metaphysical gap. The explanatory gap exists, they say, because there are two fundamental properties in the world that do not reduce to one another: Phenomenal and physical. This position is also known as 'property dualism'. A famous argument, formulated and defended at great length by David Chalmers, uses conceptual tools to argue for a metaphysical gap. When we just look at what the notion of phenomenal consciousness implies, we will find that it doesn't rule out that there could be entities functionally and physically identical to us but without phenomenal consciousness. A couple of further argumentative steps can get us from here to the conclusion that laying down the physical facts of our world does not necessitate phenomenal consciousness. I argue that this argument is compelling but that accepting the conclusion doesn't have the implication that science cannot discover what consciousness is. I begin by outlining and assessing a number of different positions philosophers and scientists have recently defended regarding the link between neurological systems and consciousness, I then argue that even if property dualism is true, that doesn't necessarily prevent the sciences from discovering what constitutes consciousness. That is, there may be no explanatory gap even if there is a metaphysical gap. (shrink)
An example is presented of a model of consciousness based on a description of the world which integrates the material and psychological aspects from the start. An indication is given of work under way to test the model.
This paper argues that the many and various conceptions of consciousness propounded by cognitive scientists and philosophers can all be understood as constituted with reference to four fundamental sorts of criterion: epistemic (concerned with kinds of consciousness), semantic (dealing with orders of consciousness), physiological (reflecting states of consciousness), and pragmatic (seeking to capture types of consciousness). The resulting four-fold taxonomy, intended to be exhaustive, suggests that all of the distinct varieties of consciousness currently encountered (...) in cognitive neuroscience, the philosophy of mind, clinical psychology, and other related fields ultimately refer to a unified natural process, analysed under four general aspects. The proposed taxonomy will, it is hoped, possess sufficient clarity to serve as a sound theoretical framework for further scientific studies, and to count as a significant step in the direction of a properly formulated unified concept of consciousness.

Giulio Tononi (2008) has offered his integrated information theory of consciousness (IITC) as a “provisional manifesto.” I critically examine how the approach fares. I point out some (relatively) internal concerns with the theory and then more broadly philosophical ones; finally I assess the prospects for IITC as a fundamental theory of consciousness. I argue that the IITC’s scientific promise does carry over to a significant extent to broader philosophical theorizing about qualia and consciousness, though not as directly (...) as Tononi suggests, since the account is much more focused on the qualitative character of experience rather than on consciousness itself. I propose understanding it as “integrated information theory of qualia” (IITQ), rather than of consciousness. (shrink)
Two of the most important concepts in contemporary philosophy of mind are computation and consciousness. This paper explores whether there is a strong relationship between these concepts in the following sense: is a computational theory of consciousness possible? That is, is the right kind of computation sufficient for the instantiation of consciousness. In this paper, I argue that the abstract nature of computational processes precludes computations from instantiating the concrete properties constitutive of consciousness. If this is (...) correct, then not only is there no viable computational theory of consciousness, the Human Mental State Multiple Realizability in Silicon Thesis is almost certainly false. (shrink)
Hypnosis appears to generate unusual—and sometimes even astonishing—changes in the contents of consciousness. Hypnotic subjects report perceiving things that are not there, they report not perceiving things that are there, and they report unusual alterations in the phenomenology of agency. In addition to apparent alterations in the contents of consciousness, hypnosis also appears to involve alterations in the structure of consciousness. According to many theorists—most notably Hilgard—hypnosis demonstrates that the unity of consciousness is an illusion (Hilgard (...) 1977). (shrink)
As far as an adequate understanding of phenomenal consciousness is concerned, representationalist theories of mind which are modelled on the information processing paradigm, are, as much as corresponding neurobiological or functionalist theories, confronted with a series of arguments based on inverted or absent qualia considerations. These considerations display the following pattern: assuming we had complete knowledge about the neural and functional states which subserve the occurrence of phenomenal consciousness, would it not still be conceivable that these neural states (...)

There are two importantly different ways in which consciousness resists incorporation into our familiar object-based conceptual schema which, when analysed, help to explain why it is regarded as such a philosophically recalcitrant phenomena. One concerns the nonconceptual nature of basic forms of conscious experience, the other concerns the fact that attempts to understand the nature of such experience in an object-based schema, as is demanded by some forms of physicalism, is inappropriate. My concern in this paper is to show (...) how certain central problems concerning our attempts to understand consciousness can be recast or dissolved if we take note of these aspects of phenomenal experience. Before addressing these issues a few words of clarification are in order. Without refinements, talk of schema has Kantian overtones. For example, consider Tye’s claim that, “Once the sensory input is brought under the appropriate schema, belief formation can take place” (Tye 1996: 66).1 Nevertheless, it is useful to talk of ‘schema’ specifically in order to waylay confusion with an issue, which Davidson long ago advertised about the impossibility of there being radically different conceptual schemes. Since I will be denying that our concepts of phenomenal consciousness can be incorporated into an object-based schema, it might be thought that advocating the existence of incommensurable conceptual schema ignores Davidson’s important lesson concerning radically different conceptual schemes. But it does not. Davidson’s point concerns the radical interpretation of an alien language of which we can make no sense. In contrast, what we have here is two different schema, both of.. (shrink)
DAVID HODGSON Abstract: This article supports the proposition that, if a judgment about the aesthetic merits of an artistic object can take into account and thereby be influenced by the particular quality of the object, through gestalt experiences evoked by the object, then we have free will. It argues that it is probable that such a judgment can indeed take into account and be influenced by the particular quality of the object through gestalt experiences evoked by it, so as to (...) make it probable that we do have free will. The proposition is supported by reference to two basic tricks apparently involved in conscious processes, which I call the qualia trick and the chunking trick; and it is suggested that these tricks make possible and indeed probable the existence of a third trick, which I call the selection trick.

Representationalists argue that phenomenal states are intentional states of a special kind. This paper offers an account of the kind of intentional state phenomenal states are: I argue that they are underived intentional states. This account of phenomenal states is equivalent to two theses: first, all possible phenomenal states are underived intentional states; second, all possible underived intentional states are phenomenal states. I clarify these claims and argue for each of them. I also address objections which touch on a range (...) of topics, including meaning holism and concept empiricism. I conclude with a brief discussion of the consequences of the proposed view for the project of naturalizing consciousness. (shrink)
