Dennett argues that the decentralized view of human cognitive organization finding increasing support in parts of cognitive science undermines talk of an inner self. On his view, the causal underpinnings of behavior are distributed across a collection of autonomous subsystems operating without any centralized supervision. Selves are fictions contrived to simplify description and facilitate prediction of behavior with no real correlate inside the mind. Dennett often uses an analogy with termite colonies whose behavior looks organized and purposeful to the external (...) eye, but which is actually the emergent product of uncoordinated activity of separate components marching to the beat of their individual drums. I examine the cognitive organization of a system steering by an internal model of self and environment, and argue that it provides a model that lies between the image of mind as termite colony and a naïve Cartesianism that views the self as inner substance.

One of the possible ways to explain the experience of visual richness is to posit a level of nonconceptual or phenomenal experience. The contents of this level of experience have recently been equated with the contents of sensory memory. It will be argued that sensory memory cannot provide these contents along two broad points. First, the conception of sensory memory relied on by these authors conflates the phenomena of visible and informational persistence, and makes use of an outdated “iconic” model (...) of visual short-term memory. Second, the way in which subjects’ reports are used to show that specific unreported contents are nevertheless experienced on a phenomenal level is questioned, using evidence on gist and high-level categorical perceptual processing. It is concluded that sensory memory, properly understood, cannot provide the kind of visual content required to support a level of richly detailed phenomenal experience, or a pictorial account of perception. Finally, alternative ways of explaining visual richness are suggested. (shrink)

This paper argues for a position of ‘dark pessimism’ towards introspective reports playing a strong justificatory role in consciousness science, based on the application of frameworks and concepts of measurement. I first show that treating introspective reports as measurements fits well within current discussions of the reliability of introspection, and argue that introspective reports must satisfy at least a minimal definition of measurement in order to play a justificatory role in consciousness science. I then show how treating introspective reports as (...) measurements makes it possible to identify the foundational methodological problems that underlie much of the current philosophical and scientific debate about the status of introspective evidence in studying consciousness. I argue that these problems prevent introspective reports from playing a strong justificatory role and resolving long-standing debates in consciousness science, both in contemporary work and in the future.

Gray takes an information-processing paradigm as his departure point, invoking a comparator as part of the system. He concludes that consciousness is to be found “in” the comparator but is unable to point to how the comparison takes place. Thus, the comparator turns out not to be an entity arising out of brain research per se, but out of the logic of the paradigm. In this way, Gray both reinvents dualism and remains trapped in the language game of his own (...) model – ending up dealing with the unknowable. (shrink)

The work in progress reported by Wright & Liley shows great promise, primarily because of their experimental and simulation paradigms. However, their tentative conclusion that macroscopic neocortex may be considered (approximately) a linear near-equilibrium system is premature and does not correspond to tentative conclusions drawn from other studies of neocortex.

The binary divide between traditional cognitivist and enactivist paradigms is tied to their respective commitments to understanding cognition as based on knowing that as opposed to knowing how. Using O’Regan’s and No¨e’s landmark sensorimotor contingency theory of perceptual experience as a foil, I demonstrate how easy it is to fall into conservative thinking. Although their account is advertised as decidedly ‘skill-based’, on close inspection it shows itself to be riddled with suppositions threatening to reduce it to a rules-and-representations approach. To (...) remain properly enactivist it must be purged of such commitments and indeed all commitment to mediating knowledge: it must embrace a more radical enactivism. (shrink)

What is consciousness? What is its importance and how is it to be described? The paper looks at some of the principal theories and their attempts to solve the “hard problem” of how consciousness is produced by nervous tissue, and attempts to close the “explanatory gap” between such (apparently) profoundly different things as subjective awareness and a physical brain. It ends with a tentative suggestion that, despite centuries of philosophical frustration, recent appeals to quantum physics may offer a glimmer of (...) hope. (shrink)

Imitation, deliberation, and mindreading are characteristically human sociocognitive skills. Research on imitation and its role in social cognition is flourishing across various disciplines. Imitation is surveyed in this target article under headings of behavior, subpersonal mechanisms, and functions of imitation. A model is then advanced within which many of the developments surveyed can be located and explained. The shared circuits model (SCM) explains how imitation, deliberation, and mindreading can be enabled by subpersonal mechanisms of control, mirroring, and simulation. It is (...) cast at a middle, functional level of description, that is, between the level of neural implementation and the level of conscious perceptions and intentional actions. The SCM connects shared informational dynamics for perception and action with shared informational dynamics for self and other, while also showing how the action/perception, self/other, and actual/possible distinctions can be overlaid on these shared informational dynamics. It avoids the common conception of perception and action as separate and peripheral to central cognition. Rather, it contributes to the situated cognition movement by showing how mechanisms for perceiving action can be built on those for active perception.;>;>The SCM is developed heuristically, in five layers that can be combined in various ways to frame specific ontogenetic or phylogenetic hypotheses. The starting point is dynamic online motor control, whereby an organism is closely attuned to its embedding environment through sensorimotor feedback. Onto this are layered functions of prediction and simulation of feedback, mirroring, simulation of mirroring, monitored inhibition of motor output, and monitored simulation of input. Finally, monitored simulation of input specifying possible actions plus inhibited mirroring of such possible actions can generate information about the possible as opposed to actual instrumental actions of others, and the possible causes and effects of such possible actions, thereby enabling strategic social deliberation. Multiple instances of such shared circuits structures could be linked into a network permitting decomposition and recombination of elements, enabling flexible control, imitative learning, understanding of other agents, and instrumental and strategic deliberation. While more advanced forms of social cognition, which require tracking multiple others and their multiple possible actions, may depend on interpretative theorizing or language, the SCM shows how layered mechanisms of control, mirroring, and simulation can enable distinctively human cognitive capacities for imitation, deliberation, and mindreading.

A traditional view of perception and action makestwo assumptions: that the causal flow betweenperception and action is primarily linear or one-way,and that they are merely instrumentally related toeach other, so that each is a means to the other.Either or both of these assumptions can be rejected. Behaviorism rejects the instrumental but not theone-way aspect of the traditional view, thus leavingitself open to charges of verificationism. Ecologicalviews reject the one-way aspect but not theinstrumental aspect of the traditional view, so thatperception and (...) action are seen as instrumentallyinterdependent. It is argued here that a betteralternative is to reject both assumptions, resultingin a two-level interdependence view in whichperception and action co-depend on dynamicallycircular subpersonal relations and as a result may bemore than merely instrumentally interdependent. Thisis illustrated by reference to motor theories ofperception and control theories of action. (shrink)

Perspective and reflection have each been considered in some way basic to phenomenal consciousness. Each has possible evolutionary value, though neither seems sufficient for consciousness. Consider an account of consciousness in terms of the combination of perspective and reflection, its relationship to the problem of other minds, and its capacity to inherit evolutionary explanation from its components.

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

B&H understate the difficulties facing their version of color realism. We doubt that they can fix reflectance types and magnitudes in a way that does not invoke relations to perceivers. B&HÂ’s account therefore resembles the dispositional or ecological accounts that they dismiss. This is a good thing, for a dispositional account is promising if understood in an ecological framework.

It is received wisdom in philosophy and the cognitive sciences that individuals can be in emotional states but groups cannot. But why should we accept this view? In this paper, I argue that there is substantial philosophical and empirical support for the existence of collective emotions. Thus, while there is good reason to be skeptical about many ascriptions of collective emotion, I argue that some groups exhibit the computational complexity and informational integration required for being in genuinely emotional states.

It would be a mistake to deny commonsense intuitions a role in developing a theory of consciousness. However, philosophers have traditionally failed to probe commonsense in a way that allows these commonsense intuitions to make a robust contribution to a theory of consciousness. In this paper, I report the results of two experiments on purportedly phenomenal states and I argue that many disputes over the philosophical notion of ‘phenomenal consciousness’ are misguided—they fail to capture the interesting connection between commonsense ascriptions (...) of pain and emotion. With this data in hand, I argue that our capacity to distinguish between ‘mere things’ and ‘subjects of moral concern’ rests, to a significant extent, on the sorts of mental states that we take a system to have. (shrink)

Thought experimental methods play a central role in empirical moral psychology. Against the increasingly common interpretation of recent experimental data, I argue that such methods cannot demonstrate that moral intuitions are produced by reflexive computations that are implicit, fast, and largely automatic. I demonstrate, in contrast, that evaluating thought experiments occurs at a near-glacial pace relative to the speed at which reflexive information processing occurs in a human brain. So, these methods allow for more reflective and deliberative processing than has (...) commonly been assumed. However, these methods may still provide insight into some human strategies for navigating unfamiliar moral dilemmas. (shrink)

Experiences of qualia, subjective sensory-like aspects of stimuli, are central to imagistic representation. Following Raffman , qualia are considered to reflect experiential knowledge distinct from descriptive, abstract, and propositional knowledge; following Jackendoff , objective neural activity is distinguished from subjective experience. It is argued that descriptive physical knowledge does not provide an adequate accounting of qualia, and philosophical scenarios such as the Turing test and the Chinese Room are adapted to demonstrate inadequacies of accounts of cognition that ignore subjective experience. (...) Arguments by Dennett and others that qualia do not exist or that qualia do not provide additional explanatory power are addressed, and it is suggested that consideration of qualia is necessary in order to explain objective behavior. The hypotheses of functional equivalence, second-order isomorphism, and psychophysical complementarity between imagery and perception are discussed, and the ability of analog and schematic models of imagery to account for qualia is examined.

How should the metaphysical hypothesis of materialism be formulated? What strategies look promising for defending this hypothesis? How good are the prospects for its successful defense, especially in light of the infamous "hard problem" of phenomenal consciousness? I will say something about each of these questions.

If POT (parieto-occipital-temporal junction) reorganization came earlier in australopithecines than in Homo, it is likely that the selective pressures were different, and not necessarily directed toward language. The brain endocast evidence for the POT in A. afarensis is actually better than it is for early Homo.

Frank Jackson formulated his knowledge argument as an argument for dualism. In this paper I show how the argument can be modified to also establish the irreducibility of the secondary qualities to the properties of physical theory, and ultimately "secondary quality eliminativism"- the view that the secondary qualities are physically uninstantiated.

I examine some recent claims put forward by L. A. Paul, Barry Dainton and Simon Prosser, to the effect that perceptual experiences of movement and change involve an (apparent) experience of ‘passage’, in the sense at issue in debates about the metaphysics of time. Paul, Dainton and Prosser all argue that this supposed feature of perceptual experience – call it a phenomenology of passage – is illusory, thereby defending the view that there is no such a thing as passage, conceived (...) of as a feature of mind-independent reality. I suggest that in fact there is no such phenomenology of passage in the first place. There is, however, a specific structural aspect of the phenomenology of perceptual experiences of movement and change that can explain how one might mistakenly come to the belief that such experiences do involve a phenomenology of passage.

It is accepted that “primary awareness” may emerge from the integration of two classes of information. It is unclear, however, why this cannot take place within the comparator rather than in conjunction with feedback to the perceptual systems. The model has plausibility in relation to the continuity of conscious experience in the normal waking state and may be extended to encompass certain aspects of the “sense of self” which are frequently disrupted in psychotic patients.

Although there has long been a division in studies of consciousness between a focus on neuronal processes or conversely an emphasis on the ruminations of a conscious self, the long-standing split between mechanism and meaning within the brain was mirrored by a split without, between information as a technical term and the meanings that messages are commonly thought to convey. How to heal this breach has posed formidable problems to researchers. Working through the history of cybernetics, one of the historical (...) sites where Claude Shannon’s information theory quickly became received doctrine, we argue that the cybernetic program as it developed through second-order cybernetics and autopoietic theory remains incomplete. In this article, we return to fundamental questions about pattern and noise, context and meaning, to forge connections between consciousness, narrative and media. The thrust of our project is to reintroduce context and narrative as crucial factors in the processes of meaning-making. The project proceeds along two fronts: advancing a theoretical framework within which context plays its properly central role; and demonstrating the importance of context by analyzing two fictions, Stanislaw Lem’s His Master’s Voice and Joseph McElroy’s Plus, in which context has been deformed by being wrenched away from normal human environments, with radical consequences for processes of meaning-making.

It may even be held that [the intellect] is the true self of each, inasmuch as it is the dominant and better part; and therefore it would be a strange thing if a man should choose to live not his own life but the life of some other than himself. Moreover . . . that which is best and most pleasant for each creature is that which is proper to the nature of each; accordingly the life of the intellect is (...) the best and the pleasantest life for man, inasmuch as the intellect more than anything else is man.

Researchers in artificial intelligence and robotics often include a timeline stretching into the future in which they predict the convergence between human and artificial intelligence. Ray Kurzweil, for example, predicts that in a mere 100 years humans and intelligent machines will become indistinguishable from one another, both ceasing to have permanent corporeal forms. This article argues that the one thing we can know for sure about the future is that when it arrives, it will be different from what we imagined. (...) The cultural work that predictions like Kurzweil’s perform is less to prognosticate the future than to shape our understanding of what it means to be human in the present. Working from the ‘sense-think-act’ paradigm foundational to work in artificial intelligence and robotics, this article argues that predictions in all three areas feed back to affect how the human is envisioned in the present. The reconfigurations these predictions bring about are to downplay consciousness, embodied cognition, and evolutionary inertia. The article concludes by critically evaluating contemporary resistances to the posthuman, especially in the writings of Rodney Brooks and Francis Fukuyama. (shrink)

In this review, we deal with two central questions of consciousness how and why, and we outline their possible future development. The question how refers to the empirical endeavor to reveal the neural correlates and mechanisms that form consciousness. On the other hand, the question why generally refers to the “hard problem” of consciousness, which claims that empirical science will always fail to provide a satisfactory answer to the question why is there conscious experience at all. Unfortunately, the hard problem (...) of consciousness will probably never completely disappear because it will always have its most committed supporters. However, there is a good chance that its weight and importance will be highly reduced by empirically tackling consciousness in the near future. We expect that future empirical endeavor of consciousness will be based on a unifying brain theory and will answer the question as to what is the function of conscious experience, which will in turn replace the implications of the hard problem. The candidate of such a unifying brain theory is predictive coding, which will have to explain both perceptual consciousness and conscious mind-wandering in order to become the truly unifying theory of brain functioning.

Contra Wilkins & Wakefield, we argue that an evolutionarily inspired approach to language must consider different facets of language (i.e., more than syntax and semantics), and must explore the possibility of nonhuman precursors. Several examples are discussed, illustrating the power of the comparative approach in illuminating our understanding of language evolution.

Tony Chemero advances the radical thesis that cognition and consciousness are actually the same thing. I question this conclusion. Even if we are the brain–body environmental synergies that Chemero and others claim, we will not be able to conclude that consciousness is just cognition because this view actually expands cognition beyond being the sort of natural kind upon which to hook phenomenal experience. Identifying consciousness with cognition either means consciousness exists at multiple levels of organization in the universe, or more (...) work needs to be done to delineate conscious cognition from other synergies. Still, while radical embodied cognition does not solve any of the hard problems associated with consciousness, this perspective allows useful insights concerning phenomenal experience. Moreover, recent neuropsychological research in action selection and projection can help us refine notions of consciousness from this embodied perspective. (shrink)

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

Our ability to tell stories about ourselves has captivated many theorists, and some have taken these developments for an opportunity to answer long-standing questions about the nature of personhood. In this essay I employ two skeptical arguments to show that this move was a mistake. The first argument rests on the observation that storytelling is revisionary. The second implies that our stories about ourselves are biased in regard to our existing self-image. These arguments undercut narrative theories of identity, but they (...) leave room for a theory of narrative self-knowledge. The theory accommodates the first skeptical argument because there are event descriptions with retrospective assertibility conditions, and it accommodates the second argument by denying us epistemic privilege in regard to our own past. The result is that we do know our past through storytelling, but that it is a contingent feature of some of our stories that they are about ourselves. (shrink)

Although this is an impressive piece of modeling work, I worry that the two models that Wright & Liley have created do not yet provide us with useful empirical information regarding brain processing.

Because our only access to color qualities is through their appearance, Byrne & Hilbert's insistence on a strict distinction between apparent colors and real colors leaves them without a principled way of determining when, if ever, we see colors as they really are.
