I argue that the logical difference between classical and quantum mechanics that Stapp (1995) claims shows quantum mechanics is more amenable to an account of consciousness than is classical mechanics is irrelevant to the problem.

The "relational mind" approach to the inner content of consciousness is developed in terms of various control structures and processing strategies and their possible neurobiological identifications in brain sites. This leads naturally to a division of consciousness into a passive and an active part. A global control structure for the "single strand" aspect of consciousness is proposed as the thalamo-nucleus reticularis thalami-cortex coupled system, which is related to experimental data on the electrical stimulation of awareness. Local control, in terms of (...) excitatory transfer from pre-processing sites to posterior working memory regions, is supported by data on subliminal perception timing and disambiguation of poorly defined percepts. The inner content of consciousness is understood as arising from the resulting relational features between inputs and stored pre-processing and episodic memories. Strong analogies are drawn between emergent properties of the model and suggested properties of "raw feels", supporting the thesis that working memories are the initial sites for the emergence of phenomenal awareness, and the frontal lobes for its further adumbration in terms of higher cognitive processing, including the creation of self.

Alva Noë’s _Action in Perception _offers a provocative and vigorous defense of the thesis that vision is enactive: visual experience depends on dispositional motor responses. On this view, vision and action are inextricably bound. In this review, I argue against enactive perception. I raise objections to seven lines of evidence that appear in Noë’s book, and I indicate some reasons for thinking that vision can operate independently of motor responses. I conclude that the relationship between vision and action is causal, (...) not constitutive. I then address three other contentious hypotheses in the book. Noë argues that visual states are not pictorial; he argues that all perception is conceptual; and he argues that the external world makes a constitutive contribution to experience. I am unpersuaded by these arguments, and I offer reasons to resist Noë’s conclusions. (shrink)

Philosophers long have noted that some sensations (particularly those of color) seem to be ineffable, or refractory to verbal description. Some proposed neurophysiological explanations of this ineffability deny the intuitive view that sensations have inherently indescribable content. The present paper suggests a new explanation of ineffability that does not have this deflationary consequence. According to the hypothesis presented here, feedback modulation of information flow in the cortex interferes with the production of narratives about sensations, thereby causing the subject to assess (...) as inadequate his or her own verbal descriptions of sensations.

A key element of the distinction between explicit and implicit cognitive functioning is the presence or absence of conscious awareness. In this review, we consider the proposal that neuropsychological disorders can best be considered in terms of a decoupling between preserved implicit or unconscious processing and impaired explicit or conscious processing. Evidence for dissociations between implicit and explicit processes in blindsight, amnesia, object agnosia, prosopagnosia, hemi-neglect, and aphasia is examined. The implications of these findings for a) our understanding of a (...) variety of neuropsychological disorders, b) the conceptualization of normal cognitive functioning, c) the neural basis of consciousness, and d) the clinical rehabilitation of brain-injured individuals are also discussed.

Carruthers, P. . Natural theories of consciousness. European Journal of Philosophy.

: A perceptual theory of introspection is one that treats introspection as a species of perception or as a special case of perception. Additionally, a perceptual theory of introspection is one for which introspection shares at least some of the essential features of perception. However, I will show that there are certain essential features of perception that introspection lacks. Moreover, those features common to perception and introspection are insufficient to distinguish perception from belief. Thus, there is good reason to deny (...) that introspection fits a perceptual model of introspection. (shrink)

This article tackles problems concerning the reduction of phenomenal consciousness to brain processes that arise in consideration of specifically epistemological properties that have been attributed to conscious experiences. In particular, various defenders of dualism and epiphenomenalism have argued for their positions by assuming special epistemic access to phenomenal consciousness. Many physicalists have reacted to such arguments by denying the epistemological premises. My aim in this paper is to take a different approach in opposing dualism and argue that when we correctly (...) examine both the phenomenology and neural correlates of phenomenal consciousness we will see that granting the epistemological premises of special access are the best hope for a scientific study of consciousness. I argue that essential features of consciousness involve both their knowability by the subject of experience as well as their egocentricity, that is, their knowability by the subject as belonging to the subject. I articulate a neuroscientifically informed theory of phenomenal consciousness. (shrink)

At least three books struggle to emerge from this volume. One book, at the level of popular science, leads us through the development of physics, from Newton's laws to Bell's inequalities, in order to argue for the relevance of consciousness to the understanding of quantum theory. This is followed by a sketch of an interpretation of quantum mechanics. Interwoven with both is a memoir of Walker's teenage girlfriend, who died of Hodgkin's disease nearly fifty years ago. The theme which holds (...) the volume together is Walker's insistence on the importance of looking beyond materialism. (shrink)

Charles Siewert's _The Significance of Consciousness_ contends that most philosophers and psychologists who have written about "consciousness" have neglected a crucial type or aspect that Siewert calls "phenomenal consciousness" and tries carefully to define. The present article argues that some philosophers, at least, have not neglected phenomenal consciousness and have offered tenable theories of it.

In his recent _The Rediscovery of the Mind_ John Searle tries to destroy cognitive science _and_ preserve a future in which a ``perfect science of the brain'' (1992, p. 235) arrives. I show that Searle can't accomplish both objectives. The ammunition he uses to realise the first stirs up a maelstrom of consciousness so wild it precludes securing the second.

This article replies to the main objections raised by the commentators on Carruthers . It discusses the question of what evidence is relevant to the assessment of dispositional higher-order thought theory; it explains how the actual properties of phenomenal consciousness can be dispositionally constituted; it discusses the case of pains and other bodily sensations in non-human animals and young children; it sketches the case for preferring higher-order to first-order theories of phenomenal consciousness; and it replies to some miscellaneous points and (...) objections.

This paper is trying to show that it is not possible to use the Knowledge argument as independent evidence for the form of non-reductionism the Modal argument argues for. To show this, Jackson's famous 'Mary' thought experiment is imagined in a zombie world. This leads to the result that there are many problems in the Mary experiment, which cannot have anything to do with phenomenal Qualia, because the Zombie-Mary would encounter them as well, and once all these problems are accounted (...) for, it is no longer clear whether a Zombie-Mary is conceivable at all. Finally, an alternative explanation for the strong non-reductive intuitions of the Mary experiment is discussed. (shrink)

: Behavioral actions can attain their intended result either when all possible details and intervening factors are controlled in advance by the action plan, or when only the final outcome is taken into account while the rest is left for on-line correction. Both ways have numerous advantages and disadvantages. The former can be applied only in very simple instances and therefore, puts very strong limits on the complexity of behavior. The latter can be used for action plans of practically unlimited (...) complexity. Such movements are free because they are determined not by their environmental conditions but by their future result. To perform them, however, the executive system must admit its principal inability to predict and control everything in advance. This produces high emotional load, that is, the anxiety to meet uncertain and uncontrollable environments. Humans avoid this feeling of uncontrollability by developing doctrines like Divine Providence or the modern neuroscientific determinism. Such doctrines are based on intuitively plausible identification of causality with necessity and predictability. To claim the principal predictability of the world , they invent arguments denying the freedom of voluntary actions. (shrink)

There are two things about Siewert's project that worry me. First, it's not clear to me that by taking Siewert's first-person approach, we can come to grasp what he means by 'consciousness'. And second, even if we are able to come to grasp what he means by this term, it's not clear to me that all the "consciousness-neglectful theoreticians of mind" - for example, Dennett, Rosenthal, and Tye - have failed to give an account of the property which Siewert's term (...) picks out.

The dissertation criticizes two analogical applications of Darwinism to the spheres of mind and culture: the Darwinian approach to creativity and memetics. These theories rely on three basic analogies: the ontological analogy states that the basic ontological units of culture are so-called memes, which are replicators like genes; the origination analogy states that novelty in human creativity emerges in a "blind" Darwinian manner; and the explanatory units of selection analogy states that memes are "egoistic" and that they can spread independently (...) of our mind. The detailed philosophical analysis offered in the dissertation shows that these three analogies rely on either wrong or trivial statements: they provide either wrong or no new descriptions or explanations of the phenomena at hand. In Chapter One, I introduce the diverse ways, in which contemporary Darwinism is used today outside of evolutionary biology. Chapter Two explains what it means to claim that something evolves in a Darwinian manner. Chapter Three to Five address each of the three analogies separately. Darwinism applied to culture and mind, at least in the way discussed in this study, is not a dangerous idea. It leads either to wrong claims or to a re-telling in Darwinian terms of what we have already known. (shrink)

The mind body problem is a continuing issue in philosophy. No surveys known to us have been conducted about the actual preferences of, for example, psychology students for particular preconceptions about the mind body relation. These preconceptions may have different practical implications for decisions concerning the object and method of research, the choice of explanatory device for psychological and other research data and for the approach of professionals in practice. A questionnaire comprising ten different preconceptions about the mind body relation (...) and other items was returned by 209 German students of various disciplines and by a second sample of 233 first year psychology students. Identity theory, interactionism and complementarity were preferred most. The students clearly believed that the preference for certain preconceptions has important practical implications. There were no differences between the students of different disciplines in the choice of preferred preconceptions about the mind body relation or in the view that these preconceptions are of practical importance.

Theories of cognition and theories of social practices and institutions have often each separately acknowledged the relevance of the other; but seldom have there been consistent and sustained attempts to synthesize these two areas within one explanatory framework. This is precisely what my dissertation aims to remedy. I propose that certain recent developments and themes in philosophy of mind and cognitive science, when understood in the right way, can explain the emergence and dynamics of social practices and institutions. Likewise, the (...) view I construct explains how social practices and institutions shape the character of cognition of their constituent agents. Moreover, I explain both cognitive and social agency under the single explanatory framework provided by Dynamic Systems Theory. Drawing upon the phenomenological tradition, "embodied, "extended", "embedded", "enactive", and "ecological" approaches to cognition, as well as the conceptual resources of Dynamic Systems Theory, I construct a theory of agency that sees cognitive and social agents as far-from-equilibrium, open, recursively self-maintenant dynamic systems. Depending on the specifics of concrete circumstances, such systems, which I call "Dynamic Embodied Agents", may develop and possess emergent capacities for error-detection, flexible learning, normative behavior, representation, self-reflection, various modes of pattern-recognition, a temporal sense of self, and even moral responsibility. Some such systems are also sensitive to perceived social influences ; while reciprocally constituting and causally affecting them. (shrink)

In the April 2002 edition of JCS I outlined the conscious electromagnetic information field theory, claiming that consciousness is that component of the brain's electromagnetic field that is downloaded to motor neurons and is thereby capable of communicating its informational content to the outside world. In this paper I demonstrate that the theory is robust to criticisms. I further explore implications of the theory particularly as regards the relationship between electromagnetic fields, information, the phenomenology of consciousness and the meaning of (...) free will. Using cemi field theory I propose a working hypothesis that shows, among other things, that awareness and information represent the same phenomenon viewed from different reference frames. (shrink)

The question asked in this paper is: How can we investigate our phenomenal experience in ways that are accurate, in principle repeatable, and produce experiences that help clarify what we understand about the processes of sensing, perceiving, moving, and being in the world? This sounds like an impossible task, given that introspection has so often in scientific circles been considered to be unreliable, and that first-person accounts are often coloured by mistaken ideas about what and how we are experiencing. The (...) first-person experiments I suggest are different from experiments done in the psychology laboratory in that there is no narrowing down of the experiments to looking at a singular aspect of a question, and that they are to be carried out in most instances in a natural or specially structured environment without strict task controls or statistical experimental design. There is no intent to replace formal second- and third-person investigation, but to use a phenomenological approach to conjoin with hard research, and to suggest ways of awareness training that can enhance the skills of researchers. I take as a model an informal phenomenological approach for experimentation. I also suggest that it is possible through directing and broadening the attention process to turn consciousness towards what is non-conscious or unattended to in order to develop an improved sensory awareness and an ability to be open to experiencing without prejudging and without expectations. The idea is to go back to experience without first creating a theoretical stance from which to interpret what happens. I conclude with some other examples of this approach. (shrink)

A significant impediment to the study of perceptual consciousness is our dependence on simplistic ideas about what experience is like. This is a point that has been made by Wittgenstein, and by philosophers working in the Phenomenological Tradition, such as Husserl and Merleau-Ponty. Importantly, it is an observation that has been brought to the fore in recent discussions of consciousness among philosophers and cognitive scientists who have come to feel the need for a more rigorous phenomenology of experience. The central (...) thought of this paper is that art can make a needed contribution to the study of perceptual consciousness. The work of some artists can teach us about perceptual consciousness by furnishing us with the opportunity to have a special kind of reflective experience. In this way, art can be a tool for phenomenological investigation. The paper focuses on the work of Richard Serra and offers a comparison of his work with that of Tony Smith. (shrink)

This dissertation concerns the location and nature of phenomenal qualities. Arguably, these qualities naively seem to belong to perceived external objects. However, we also seem to experience phenomenal qualities in hallucinations, and in hallucinations we do not perceive any external objects. I present and argue for a theory of the phenomenal qualities, "brain theory", which claims that all phenomenal qualities we experience are physical properties instantiated in the brain, regardless of whether they are experienced in veridical perceptions or in hallucinations. (...) I begin by more carefully identifying the phenomenal qualities, discussing how they are related to "qualia" and "phenomenal character". Then I present brain theory, and investigate its implications for the perceptual relations we stand in to external objects, noting that it is mostly neutral. I also compare brain theory to a similar theory of perception advocated by Bertrand Russell. Next, I provide an overview over the competing theories of phenomenal qualities, and relate them to theories of perception, such as representationalism, qualia theory, sense data theory and disjunctivism. The majority of my argumentation for brain theory focuses on arguing that the phenomenal qualities are instantiated in the brain, rather than on arguing that they are physical properties. Instead, I largely assume physicalism. However, even independently of the physicalism assumption, I show that we have reason to believe that phenomenal qualities are experienced in hallucinations, and that qualities experienced in hallucinations are instantiated in internal objects, such as our brains or sense data. In the first step towards this conclusion I argue that theories which deny that phenomenal qualities are experienced in hallucinations face serious problems. In the next step I argue that theories which deny that phenomenal qualities experienced in hallucinations are instantiated in internal objects face serious problems. Finally, an important part of the argumentation is my replies to objections against brain theory, including common sense objections and the "observation objection". From these conclusions, together with the physicalism assumption, I infer that we have reason to believe that brain theory is true about hallucinations. On this basis, I then argue, through a generalizing argument, that the same is the case for veridical perceptions. (shrink)

Ten models of consciousness are discussed. The models are proposed by individuals who do not seem to understand “the hard problem of phenomenal consciousness”, presumably because they have no qualia themselves. As the Zombie’s proposals are dismissed, the quality of their comments and contributions rises. It is concluded that no premature solution to the hard problem should be proposed at this point; instead it is suggested that the problem must first be appreciated to full extent by scientists and students of (...) all faculties dealing with information processing in the human brain. Ultimately, the question is why the brain, when in a particular state, experiences its own activity qualitatively. The answer to that question will probably expand the current ontology of physics.

Questions concerning the nature of representation and what representations are about have been a staple of Western philosophy since Aristotle. Recently, these same questions have begun to concern neuroscientists, who have developed new techniques and theories for understanding how the locus of neurobiological representation, the brain, operates. My dissertation draws on philosophy and neuroscience to develop a novel theory of representational content.

In this dissertation, I argue that an account of epistemic injustice sensitive to interlocking oppressions must take us beyond injustice to human knowers. Although several feminist epistemologists argue for the incorporation of all forms of oppression into their analyses, feminist epistemology remains for the most part an anthropocentric enterprise. Yet insofar as a reduction to animal irrationality has been central to the epistemic injustice of both humans and animals, I propose that in addition to axes of gender, race, class and (...) sex, feminist epistemology must register the animal-human dichotomy as a fundamental driving mechanism inherent in epistemic injustice. From the perspective of a truly liberatory epistemology, I thus argue for an expanded account of epistemic injustice that is both 1) sufficiently attentive to the way injustices to human knowers continue to rely on animal oppression and 2) that accommodates epistemic injustices against animal knowers.

This dissertation examines representationalism about sensory phenomenology—the claim that for a sensory experience to have a particular phenomenal character is a matter of it having a particular representational content. I focus on a particular issue that is central to representationalism: whether reductive versions of the theory should be internalist or externalist. My primary goals are to demonstrate that externalist representationalism fails to provide a reductive explanation for phenomenal qualities, and to present a reductive internalist version of representationalism that utilizes the (...) empirical framework of psychophysics and neuroscience to develop a philosophical theory of content. The bulk of the project is an attempt to provide the outlines of what such an empirically-based representationalist theory would look like. In chapter 2, I argue that reductive externalist representationalism fails because it is vulnerable to the problem of bad structural correlation: the mismatch between the structure of phenomenal qualities and the structure of physical properties “tracked” by our sensory systems with which phenomenal qualities are identified. In chapter 3, I develop the outlines of a reductive internalist version of representationalism that characterizes phenomenal qualities as modes of presentation of sensory representations that can be reductively characterized in terms of a location in a psychophysically-defined quality space, which can in turn be given a neurophysiological interpretation. In addition, I argue that the neural mechanisms responsible for the representation of spatial locations and visual objects serve a referential role in sensory psychosemantics that grounds the intentionality of sensory states. In chapter 5 I provide a detailed account of the representation of spatial locations in sensory experience, and in chapter 6 I examine the “binding problem”, demonstrating how object-based sensory representations function to demonstratively pick out sensory individuals without explicitly representing any of their features. I describe the resulting view as methodological representationalism: an attempt to demonstrate how a particular philosophical theory of sensory phenomenology can be integrated into the empirical framework of cognitive science, and thereby provide an explanatory psychosemantic framework for sensory phenomenology that is valuable to both philosophers and cognitive scientists.

Defenders of the Knowledge Argument contend that physicalism is false because knowing all the physical truths is not sufficient to know all the truths about the world. In particular, proponents of the Knowledge Argument claim that physicalism is false because the truths about the character of conscious experience are not knowable from the complete set of physical truths. This dissertation is a defense of the Knowledge Argument. Chapter one characterizes what physicalism is and provides support for the claim that if (...) knowing all the physical truths is not sufficient to know all the truths about the world, then physicalism is false. In chapter two, I defend the claim that knowing all the physical truths is not sufficient for knowing all the truths about the world. In addition to mounting a prima facie case for the knowledge intuition, I present and defend an epistemology grounded in direct acquaintance to provide a more substantive argument to accept it. Chapters three through five address the physicalist objections to the Knowledge Argument. The first set of objections advocates that knowing all the physical truths is, in fact, sufficient for knowing all the truths about the world. The next set of objections admits that there is some sense in which knowing all the physical truths is not sufficient for knowing all the truths about the world. However, these objections maintain that the kind of knowledge that is absent from the complete set of physical truths is know-how or knowledge by acquaintance, and not factual or propositional knowledge. The final set of objections maintain that the kind of propositional knowledge that is left out of the complete set of physical truths is compatible with physicalism. My response to these objections is part of advancing my prima facie case for the Knowledge Argument. The final chapter addresses a structural question that pertains to the Knowledge Argument. Some philosophers have maintained that the structure of the Knowledge Argument invites a kind of self-refutation of any systematic account of reality. The concern is that the Knowledge Argument proves too much, and that the dualist who uses the argument to refute physicalism risks the argument defeating his own position. I will argue that the Knowledge Argument does not refute dualism. (shrink)

Spontaneous actions are preceded by brain signals that may sometimes be detected hundreds of milliseconds in advance of a subject's conscious intention to act. These signals have been claimed to reflect prior unconscious decisions, raising doubts about the causal role of conscious will. Murakami et al. (2014. Nat Neurosci 17: 1574–1582) have recently argued for a different interpretation. During a task in which rats spontaneously decided when to abort waiting, the authors recorded neurons in the secondary motor cortex. The neural (...) activity and relationship to action timing was parsimoniously explained using an integration-to-bound model, similar to those widely used to account for evidence-based decisions. In this model, the brain accumulates spontaneously occurring inputs voting for or against an action, but only commits to act once a certain threshold is crossed. The model explains how spontaneous decisions can be forecast (partially predicted) by neurons that reflect either the input or output of the integrator. It therefore presents an explicit hypothesis capable of rejecting the claim that such predictive signals imply unconscious decisions. We suggest that these results can inform the current debate on free will but must be considered with caution. (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)

Conscious events interact with memory systems in learning, rehearsal and retrieval (Ebbinghaus 1885/1964; Tulving 1985). Here we present hypotheses that arise from the IDA computional model (Franklin,Kelemen and McCauley 1998; Franklin 2001b) of global workspace theory (Baars 1988, 2002). Our primary tool for this exploration is a flexible cognitive cycle employed by the IDA computational model and hypothesized to be a basic element of human cognitive processing. Since cognitive cycles are hypothesized to occur five to tentimes a second and include (...) interaction between conscious contents and several of the memory systems, they provide the means for an exceptionally fine-grained analysis of various cognitive tasks. We apply this tool to the small effect size of subliminal learning compared to supraliminal learning, to process dissociation, to implicit learning, to recognition vs. recall, and to the availability heuristic in recall. The IDA model elucidates the role of consciousness in the updating of perceptual memory, transient episodic memory, and procedural memory. In most cases, memory is hypothesized to interact with conscious events for its normal functioning. The methodology of the paper is unusual in that the hypotheses and explanations presented are derived from an empirically based, but broad and qualitative computational model of human cognition.

The identity of conscious states and brain states must remain a mystery until we find a way of characterising both sides of the equation in terms that have the same ‘dimensions’. In this paper I stress the need for ‘dual currency concepts’ that not only are but can be seen to be as appropriate for talking about, say, the experience of pain as for talking about the corresponding working of the brain. In the light of evolutionary theory I make a (...) radically new proposal for what the common dimension is, centred on the idea of ‘authorship’. (shrink)

Brain-centered theories of consciousness seem to face insuperable difficulties. While some philosophers now doubt that the hard problem of consciousness will ever be solved, others call for radically new approaches to conscious experience. In this article I resurrect a largely forgotten approach to consciousness known as neorealism. According to neorealism, consciousness is merely a part, or cross-section, of the environment. Neorealism implies that all conscious experiences, veridical or otherwise, exist outside of the brain and are wholly independent of being perceived (...) or not; nonveridical perceptions of the environment over an arbitrarily short period of time are supposed to be objective constituents of the environment over a more extended time scale. I argue here that neorealism fares at least as well as brain-centered theories of consciousness on a number of fundamental issues. On one fundamental issue—the nature of the relation between veridical and nonveridical perceptions—neorealism outperforms its competitors. (shrink)

From a behaviorist perspective, the desire to upload “minds” is already being realized on a mass, hyper-industrial scale thanks to the convergence of cognitive computing and Big Data. The accusation is that the “mind” is not an entity that exists intracranially. Instead, it is conceived as a process of individuation, which occurs in different modes and numbers. Some narratives of mind-uploading and technics in popular culture are explored: Transcendence (2014, dir. Wally Pfister) and Player Piano by Kurt Vonnegut. The discussed (...) issues consider Bernard Stiegler’s phenomenological notion of originary default and Thierry Bardini’s analysis of junk. Several questions are raised regarding miscalculations, accidents, in addition to Nicolas Agar’s discussion on the end of humanity, and Daniel Dennett’s Multiple Drafts theory within the context of exteriorization, which is considered as constitutive of interiority.

Richard Jeffrey said that Newcomb’s Problem may be seen “as a rock on which... Bayesianism... must founder” and the problem has been almost universally conceived as reconciling the science-fictional features of the decision problem with a plausible causal analysis. Later, Jeffrey renounced his earlier position that accepted Newcomb problems as genuine decision problems, suggesting “Newcomb problems are like Escher’s famous staircase”. We may interpret this to mean that we know there can be no such thing, though we see no local (...) flaw in the puzzle. In this paper, I develop the critique of Slezak to show that Jeffrey’s analogy is apt for a puzzle whose logical features can be precisely articulated and I propose an easily realizable experiment that convincingly supports this analysis. I suggest that these real-life analogs of Newcomb’s Problem have diverted attention from the essential function of the science-fiction of a predicting demon. Following Eells, similarities with realistic problems such as Prisoner’s Dilemma and common cause cases have suggested that Newcomb’s Problem may be given a coherent description and realized in some way consistent with classical causation. However, the peculiarity of the apparent link between one’s choice and the previously determined contents of the second box is the central, defining feature of Newcomb’s Problem. I argue that the predictor may not be merely a fiction providing insufficient “extra information” as both McKay and Levi suggest. Rather, I suggest that the decision problem permits a precise specification revealing the source of the notorious perplexity. Notwithstanding efforts to rescue the coherence of Newcomb’s Problem and a classical causal account, a simulation of the decision problem establishes the correctness of my analysis and, thereby, hopefully ending the debate.

In philosophy, the last thirty years or so has seen a split between 'simulation theorists' and 'theory-theorists', with a number of variations on each side. In general, simulation theorists favour the idea that our knowledge of others is based on using ourselves as a working model of what complex psychological creatures are like. Theory-theorists claim that our knowledge of complex psychological creatures, including ourselves, is theoretical in character and so more like our knowledge of the world in general. The body (...) of this paper is divided into three parts. In Part I, I introduce the 'contrastive case' of autism. Autism is a developmental disorder that has recently become the focus of sustained philosophical and psychological attention because of the selective way in which it affects individuals' social capacities. Theory-theorists argue that autistic children's unique profile of assets and deficits is most fruitfully explained by their inability to develop and deploy a theory of mind. After considering the strengths of this hypothesis, I claim theory-theorists face two unresolved difficulties: explaining why high-functioning autistics who develop some theory of mind capacities still fail to engage in normal psychological knowing; and explaining why autistics are generally as unknowable to us in the privileged sense of normal psychological knowing as we are to them. In Part II, I provide the theoretical framework for addressing these challenges by developing an account of normal psychological knowing as psycho-practical expertise. In Part III, I return to the problem of autism, showing how this psycho-practical approach to normal psychological knowing may further suggest how to encompass various aspects of the disorder that tend to be ignored under the prevailing theory-theory approach.

According to the sensorimotor account, vision does not imply theconstruction of internally generated representations of the environment, butit isthe skillful exercise of the sensorimotor contingencies obeying sense-specific laws. In this short study, I focus on the notion of “sensorimotor law” and characterize the kind of explanation providedby the sensorimotor theory as a form of covering law model. I then question the nature of such sensorimotor laws and describe them as mechanisms. I show that a mechanistic interpretation provides a better account (...) of the sensorimotor invariances, which fosters us to rebalance the explanatory burden of sensorimotor action and information. Finally, I show that the question of the roleof representations within the sensorimotor theory should be reconsidered. (shrink)

The so-called “Baldwin Effect” has been studied for years in the fields of Artificial Life, Cognitive Science, and Evolutionary Theory across disciplines. This idea is often conflated with genetic assimilation, and has raised controversy in trans-disciplinary scientific discourse due to the many interpretations it has. This paper revisits the “Baldwin Effect” in Baldwin’s original spirit from a joint historical, theoretical and experimental approach. Social Heredity – the inheritance of cultural knowledge via non-genetic means in Baldwin’s term – is also taken (...) into consideration. I shall argue that the Baldwin Effect can occur via social heredity without necessity for genetic assimilation. Computational experiments are carried out to show that when social heredity is permitted with high fidelity, there is no need for the assimilation of acquired characteristics; instead the Baldwin Effect occurs as promoting more plasticity to facilitate future intelligence. The role of mind and intelligence in evolution and its implications in an extended synthesis of evolution are briefly discussed. (shrink)

It has been suggested, on the one hand, that quantum states are just states of knowledge; and, on the other, that quantum theory is merely a theory of correlations. These suggestions are confronted with problems about the nature of psycho-physical parallelism and about how we could define probabilities for our individual future observations given our individual present and previous observations. The complexity of the problems is underlined by arguments that unpredictability in ordinary everyday neural functioning, ultimately stemming from small-scale uncertainties (...) in molecular motions, may overwhelm, by many orders of magnitude, many conventionally recognized sources of observed ``quantum'' uncertainty. Some possible ways of avoiding the problems are considered but found wanting. It is proposed that a complete understanding of the relationship between subjective experience and its physical correlates requires the introduction of mathematical definitions and indeed of new physical laws.

Carruthers proposes that for a mental state to be conscious , it must be present in a.

This paper explores the possibility of a neuroscientific explanation of consciousness, and what such an explanation might look like. More specifically, I will be concerned with the claim that for any given experience there is neural representational system that constitutes the minimal supervenience base of that experience. I will call this hypothesis the minimal supervenience thesis. I argue that the minimal supervenience thesis is subject to two readings, which I call the localist and holist readings. Localist theories seek to identify (...) the minimal supervenience base for specific experiences. They sideline questions about the nature of creature consciousness, treating the neural basis of creature consciousness as merely a causally necessary background condition for a particular conscious experience. Holists on the other hand prioritise creature consciousness and argue that we can only account for particular states of consciousness in the context of an account of creature consciousness. I argue that any scientific explanation of consciousness must account for what I will call a minimal sense of self that is intrinsic to every conscious state. Holist theories are best able to accommodate this feature. I end by arguing that the Dynamic Sensorimotor account of consciousness can be combined with a holist account of the neural basis of consciousness. Such a combination of views corrects for the opposition to the minimal supervenience thesis found in some prominent defenders of the DSM account . It also provides a framework for developing a neuroscientific account of the minimal sense of self. (shrink)

This paper attempts to locate modern Zen and psychoanalysis in terms of contemporary philosophy of mind, particularly in view of dominant theories of cognitivism that see the mind as informational and material, with meaning being mere information in disguise. Psychoanalysis and modern Zen hold to the contrary view that the mind is “semantic,” not “syntactic,” and that the meanings we have in our heads are not reducible to the physical informational processes from which they have emerged. Meaning, as non-reducible, is (...) infinite and uncaused. However, the structure of meaning entails a split between a knower and what is known. This split creates problems in the mind which can be confronted through more, not less, engagement with the meanings in our minds, until we are self-aware and, perhaps, self-identical, with the mechanisms of consciousness that produce the meanings in our head. Such self-awareness is seen as being self-liberating rather than self-reducing. (shrink)

Comparisons between audiobook listening and print reading often boil down to the fact that audiobooks impose limitations on the recipient’s continuous in-depth reflection. As a result, audiobook listening is considered a shallow alternative to reading. This chapter critically revisits the following three intuitions commonly associated with such comparisons: 1) Audiobooks elicit more mental imagery than print. 2) Audiobooks invite more inattentive processing than print. 3) Audiobook listening is more contingent on the environment than print reading. Instead of postulating the superiority (...) of print over audio, the chapter argues that the three intuitions are largely based on a misconception of print reading, its experiential characteristics, and its function.

I argue in opposition to Sam Rakover that the current lack of fully adequate theories of the subjective and qualitative aspects of mind does not justify the adoption of what he calls “methodological dualism” (Rakover, this issue). Scientific understanding of consciousness requires the continuation of attempts to explain it in terms of the neural mechanisms that support it. It would be premature to adopt a methodological stance that could foreclose on the possibility of more reductionistic approaches. The effects of such (...) a stance would be especially pernicious insofar as methodological dualism lacks rigorous methods for testing specific models. (shrink)

Our understanding of human visual perception generally rests on the assumption that conscious visual states represent the interaction of spatial structures in the environment and our nervous system. This assumption is questioned by circumstances where conscious visual states can be triggered by external stimulation which is not primarily spatially defined. This work discusses psychophysical experiments investigating flicker induced subjective experiences of colour and form. Using the presentation of spatially uniform flicker with a precise temporal resolution it is shown that subjective (...) experiences do not only depend on stimulation frequency, but also on stimulation phase. In addition, the occurrence of one subjective experience appears to be associated with the occurrence of others. The phenomenology of subjective colour and form is further explored and the physiological mechanisms underlying subjective colour are investigated using electroencephalography. While these data indicate that conscious visual experience may be evoked directly by particular variations in the flow of spatially unstructured light over time it may be assumed that the systems reponsible are essentially temporal in character and capable of representing a variety of visual forms and colours, coded in different frequencies or at different phases of the same processing rhythm.
