    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 (DSM) 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 (e.g. Alva NoĂ« and Evan Thompson). It also provides a framework for developing a neuroscientific account of the minimal sense of self.L’article cherche Ă  savoir si une explication neuroscientifique de la conscience est possible et Ă  quoi elle pourrait ressembler.

    Naturalising phenomenology: using phenomenology to close the explanatory gap

    Get PDF
    Naturalists and Phenomenologists have contrasting conceptions of philosophy and its purpose. The naturalist takes philosophy to be a discipline that is continuous with the natural sciences, while phenomenology defines itself by its opposition to such a view of philosophy. My thesis project argues that this opposition is unfounded.The phenomenologist takes the world we consciously experience to be a world of subjective facts. My thesis begins by introducing the phenomenologist's conception of a subjective fact. I call a situation "a subjective fact" when it essentially involves a subject of experience. I go on to explain why phenomenologists thought the world we experience is a world of subjective facts.Naturalists hold that all facts are objective facts, and it is generally supposed that no fact can be both subjective and objective. I argue that it is the contrast between these two kinds of facts that led phenomenologists to conclude that a naturalistic theory of mind will have no place in it for subjective facts.A central claim in my PhD thesis is that a fact can be both subjective and objective. I argue that a naturalist could accept the existence of subjective facts if s/he could admit the existence of situations that essentially involve relations to subjects of experience. If a naturalist is to accept the existence of situations of this kind, a naturalist account must be given of what it is to be a subject of experience.A creature becomes a subject of experience, I claim, when it tokens representations with reflexive content. I offer an account of what it is for a representation to have reflexive content in terms of a special kind of representation I call 'an implicit self-representation'. I offer a naturalist account of implicit self-representation by appealing to the role this notion of representations plays in embodied and situated accounts of perception.I conclude that naturalism can admit into its ontology subjects of experience. The phenomenologist says naturalism must exclude subjective facts with the result that our relation to the world gets misdescribed. I argue that naturalists can admit subjective facts, thereby opening up the possibility of a naturalised phenomenology

    Embodying addiction: a predictive processing account

    Get PDF
    In this paper we show how addiction can be thought of as the outcome of learning. We look to the increasingly influential predictive processing theory for an account of how learning can go wrong in addiction. Perhaps counter intuitively, it is a consequence of this predictive processing perspective on addiction that while the brain plays a deep and important role in leading a person into addiction, it cannot be the whole story. We’ll argue that predictive processing implies a view of addiction not as a brain disease, but rather as a breakdown in the dynamics of the wider agent-environment system. The environment becomes meaningfully organised around the agent’s drug-seeking and using behaviours. Our account of addiction offers a new perspective on what is harmful about addiction. Philosophers often characterise addiction as a mental illness because addicts irrationally shift in their judgement of how they should act based on cues that predict drug use. We argue that predictive processing leads to a different view of what can go wrong in addiction. We suggest that addiction can prove harmful to the person because as their addiction progressively takes hold, the addict comes to embody a predictive model of the environment that fails to adequately attune them to a volatile, dynamic environment. The use of an addictive substance produces illusory feedback of being well-attuned to the environment when the reality is the opposite. This can be comforting for a person inhabiting a hostile niche, but it can also prove to be harmful to the person as they become skilled at living the life of an addict, to the neglect of all other alternatives. The harm in addiction we’ll argue is not to be found in the brains of addicts, but in their way of life

    Embraining Culture: Leaky Minds and Spongy Brains

    Get PDF
    We offer an argument for the extended mind based on considerations from brain development. We argue that our brains develop to function in partnership with cognitive resources located in our external environments. Through our cultural upbringing we are trained to use artefacts in problem solving that become factored into the cognitive routines our brains support. Our brains literally grow to work in close partnership with resources we regularly and reliably interact with. We take this argument to be in line with complementarity or “second-wave” defences of the extended mind that stress the functional differences between biological elements and external, environmental resources in putative cases of extended cognition. Complementarity defences argue that many of the kinds of cognition humans excel at can only be accomplished by brains working together with a body that directly manipulates and acts on the world [Rowlands (1999); Menary (2007); Sutton (2010)]. We argue that complementarity and functionalist defences of the extended mind aren’t opposed, but that complementarity considerations can provide much needed and hitherto under exploited leverage in defending EMT. Moreover, the developmental work we will describe adds extra weight to the complementarity case for EMT

    Diachronic Constitution

    Get PDF
    It is often argued that constitution and causation are different kinds of metaphysical relations. Constitution, like other grounding relations, is assumed to be synchronic (it happens at a time), while causation is diachronic (it happens over time). It is this synchronic-diachronic division that, more than other difference-makers, is argued to distinguish grounding relations such as constitution from causation. This paper develops an account of a species of constitution that happens over time. We call this type of constitution, diachronic constitution. We show how diachronic constitution is a consequence of a common type of causation, often ignored in metaphysical discussions of causation: continuous reciprocal causation. Hence, constitution is not only sometimes like causation; it can also be a form of causation. We argue that temporalising the constitution relation is neither as remarkable nor as problematic as it might initially seem. It is inevitable, given local interactions between microscale and macroscale states in dynamical systems
