There are many facets to mental life and mental experience. In this chapter, I attempt to account for some central characteristics among those facets. I argue that normative function and representation are emergent in particular forms of the self-maintenance of far from thermodynamic equilibrium systems in their essential far-from-equilibrium conditions. The nature of representation that is thereby modeled.

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

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.

It is the ambition of evolutionary psychology to explain how the basic features of human mental life came to be selected because of their contribution to biological survival. Counted among the most basic must be the subjective qualities of conscious sensory experience: the felt redness we experience on looking at a ripe tomato, the felt saltiness on tasting an anchovy, the felt pain on being pricked by a thorn. But, as many theorists acknowledge, with these qualia, the ambition of evolutionary (...) psychology may have met its match. Everyone agrees that a trait can only contribute to an organism's biological survival in so far as it operates in the public domain. Yet almost everyone also agrees that the subjective quality of sensory experience is (at least for all practical purposes) private and without external influence. Then, maybe we must either concede that the subjective quality of sensations cannot after all have been determined by selection (even if this is theoretically depressing) or else demonstrate that the quality of sensations is not as private as it seems to be (even if this is intuitively unconvincing). No. I believe neither of these solutions to the puzzle is in fact the right one. I argue instead that the truth is that the quality of sensations has indeed been shaped by selection in the past, despite the fact that it is today effectively private. And this situation has come about as a result of a remarkable evolutionary progression, whereby the primitive activity of sensing slowly became "privatized" - that is to say, removed from the domain of overt public behavior and transformed into a mental activity that is now, in humans, largely if not exclusively internal to the subject's mind.

Reflexive consciousness evolved in the context of early human social life, as a means by which 'natural psychologists' could develop working models of their own and others' minds.

What are the psychological functions that could only be performed consciously? People have intuitively assumed that many acts of volition are not influenced by unconscious information. These acts range from simple examples such as making a spontaneous motor movement, to higher cognitive control. However, the available evidence suggests that under suitable conditions, unconscious information can influence these behaviors and the underlying neural mechanisms. One possibility is that stimuli that are consciously perceived tend to yield strong signals in the brain, which (...) makes us think that consciousness has the function of such strong signals. However, if we could create conditions where the stimuli could yield strong signals but not the conscious experience of perception, perhaps we would find that such stimuli are just as effective in influencing volitional behavior. Future studies that focus on clarifying this issue may tell us what the defining functions of consciousness are. (shrink)

The question of whether conscious experience has any functional purpose depends on a more fundamental issue concerning the nature of conscious experience. In particular, whether the world of experience is the external world itself, as suggested by direct realism, or whether it is merely a virtual- reality replica of that world in an internal representation, as in indirect realism, or representationalism. There is an epistemological problem with the notion of direct realism, for we cannot be consciously aware of objects beyond (...) the sensory surface. Therefore the world of experience can only be an internal replica of the external world. This in turn validates a phenomenological approach to studying the nature of the perceptual representation in the brain. Phenomenology reveals that the representational strategy employed in the brain is an analogical one, in which objects are represented in the brain by constructing full spatial replicas of those objects in an internal representation.

Compatibilists often think they can afford to be complacent with regard to scientific findings. But there are apparent threats to free will besides determinism. Robert Kane has recently claimed that if consciousness does not initiate action, all accounts of free will go down, compatibilist and incompatibilist. Some cognitive scientists argue that in fact consciousness does not initiate action. In this paper I argue that they are right (though not for the reasons they advance): as a matter of fact consciousness does (...) not initiate action. But, I contend, Kane is wrong in thinking that it follows that we have no free will. I sketch how we might have free will in spite of the finding that consciousness does not initiate action, and remark on the implications for several well-known accounts of responsibility, include Clarke's agent-causal theory and Fischer and Ravizza's reasons-responsiveness account.

In a recent article, George Sher argues that a realistic conception of human agency, which recognizes the limited extent to which we are conscious of what we do, makes the task of specifying a conception of the kind of control that underwrites ascriptions of moral responsibility much more difficult than is commonly appreciated. Sher suggests that an adequate account of control will not require that agents be conscious of their actions; we are responsible for what we do, in the absence (...) of consciousness, so long as our obliviousness is explained by some subset of the mental states constitutive of the agent. In this response, I argue that Sher is wrong on every count. First, the account of moral responsibility in the absence of consciousness he advocates does not preserve control at all; rather, it ought to be seen as a variety of attributionism (a kind of account of moral responsibility which holds that control is unnecessary for responsibility, so long as the action is reflective of the agent’s real self). Second, I argue that a realistic conception of agency, that recognizes the limited role that consciousness plays in human life, narrows the scope of moral responsibility. We exercise control over our actions only when consciousness has played a direct or indirect role in their production. Moreover, we cannot escape this conclusion by swapping a volitionist account of moral responsibility for an attributionist account: our actions are deeply reflective of our real selves only when consciousness has played a causal role in their production.

In this paper, we present an account of phenomenal con- sciousness. Phenomenal consciousness is experience, and the _problem _of phenomenal consciousness is to explain how physical processes.

According to qualia-epiphenomenalism, phenomenal properties are causally inefficacious, they are metaphysically distinct from, and nomologically connected with certain physical properties. The present paper argues that the claim of causal inefficacy undermines any effort to establish the alleged nomological connection. Epiphenomenalists concede that variations of phenomenal properties in the absence of any variation of physical/functional properties are logically possible, however they deny that these variations are nomologically possible. But if such variations have neither causal nor functional consequences, there is no way (...) to detect themanot only in scientific experiments, but also from the first-person perspective. Since neither third- nor first- person evidence can rule out the actual occurrence of such dissociations, the alleged nomological connection between phenomenal and physical properties cannot be established, in principle. As a consequence, the distinction between logical and nomological possibility breaks down and it cannot be ruled out that such dissociations occur in an unlimited number of cases. (shrink)

There is an argument (Medlin, 1967; Place, 1988) whichshows conclusively that if qualia are causallyimpotent we could have no possible grounds forbelieving that they exist. But if, as this argumentshows, qualia are causally potent with respect to thedescriptions we give of them, it is tolerably certainthat they are causally potent in other morebiologically significant respects. The empiricalevidence, from studies of the effect of lesions of thestriate cortex (Humphrey, 1974; Weiskrantz, 1986;Cowey and Stoerig, 1995) shows that what is missing inthe absence (...) of visual qualia is the ability tocategorize sensory inputs in the visual modality. This would suggest that the function of privateexperience is to supply what Broadbent (1971) callsthe evidence on which the categorization ofproblematic sensory inputs are based. At the sametime analysis of the causal relation shows that whatdifferentiates a causal relation from an accidentalspatio-temporal conjunction is the existence ofreciprocally related dispositional properties of theentities involved which combine to make it true thatif one member of the conjunction, the cause, had notexisted, the other, the effect, would not haveexisted. The possibility that qualia might bedispositional properties of experiences which, as itwere, supply the invisible glue that sticks cause toeffect in this case is examined, but finallyrejected.

Recently some philosophers interested in consciousness have begun to turn their attention to the question of what evolutionary advantages, if any, being conscious might confer on an organism. The issue has been pressed in recent dicussions involving David Chalmers, Todd Moody, Owen Flanagan and Thomas Polger, Daniel Dennett, and others. The purpose of this essay is to consider some of the problems that face anyone who wants to give an evolutionary explanation of consciousness. We begin by framing the problem in (...) the context of some current debates. Then we. (shrink)

MS, under submission, derived from a Powerpoint presentation at a Conference on Consciousness, Memory, and Perception, in honor of Larry Weiskrantz, City University, London, September 15, 2006.

Various hypotheses about the importance of psycho-neural concomitants are reviewed and their implications discussed for the 'easy' and 'hard' problems of consciousness -- especially, as viewed by cognitive and ecological psychology. In Ecological Psychology, where the subjective-objective dichotomy is repudiated, these concepts are without foundation, and are replaced by informed awareness, which is argued to play an important, perhaps, indispensable role in goal- directed actions and thus to have survival value. The significance of informed awareness is illustrated in several real- (...) world goal-directed tasks. (shrink)

Investigations of the function of consciousness in human information processing have focused mainly on two questions: (1) where does consciousness enter into the information processing sequence and (2) how does conscious processing differ from preconscious and unconscious processing. Input analysis is thought to be initially "preconscious," "pre-attentive," fast, involuntary, and automatic. This is followed by "conscious," "focal-attentive" analysis which is relatively slow, voluntary, and flexible. It is thought that simple, familiar stimuli can be identified preconsciously, but conscious processing is needed (...) to identify complex, novel stimuli. Conscious processing has also been thought to be necessary for choice, learning and memory, and the organization of complex, novel responses, particularly those requiring planning, reflection, or creativity.
