Neither personal belief nor a phenomenal self model can exist without attachment to a pre-reflective core self.

O presente artigo objetiva fornecer uma apresentação crítica, compreensiva e inédita na língua portuguesa do Processamento Preditivo (PP) – um esquema teórico para a compreensão da cognição que propõe uma inversão de nosso entendimento padrão da ação, percepção, sensação e sua relação. Aqui, nosso objetivo primário será introduzir os principais conceitos e ideias do PP, tratando-o como um modelo moderadamente corporificado de cognição e analisando suas credenciais como uma proposta teórica unificadora. Para tanto, partiremos de uma contextualização histórica de algumas (...) correntes de pensamento que teriam fomentado seu desenvolvimento inicial, passando por uma descrição não-matemática do Princípio da Energia Livre, que fundamenta e subentende a atuação de suas especificidades para, então, esclarecermos o papel que, segundo o PP, a inferência bayesiana, a minimização dos erros de predição e a chamada Inferência Ativa possuiriam na manutenção homeostática de nossos cérebros e corpos preditivos. Por fim, forneceremos uma síntese de algumas consequências daquilo que o PP poderia trazer à compreensão contemporânea do cérebro e comportamento humanos, concluindo que, embora sua descrição da cognição como um processo preditivo único e contínuo prometa eventualmente unificar paradigmas explicativos e níveis de análise distintos, por ora, talvez seja melhor concebê-lo de forma mais modesta, como uma ferramenta ou heurística para nos auxiliar a repensar vários dos tópicos centrais ao estudo científico e filosófico da mente.

A group of philosophers suggests that a sense of mineness intrinsically contained in the phenomenal structure of all conscious experiences is a necessary condition for a subject to become aware of himself as the subject of his experiences i.e. self-awareness. On this view, consciousness necessarily entails phenomenal self-awareness. This paper argues that cases of delusions of thought insertion undermine this claim and that such a phenomenal feature plays little role in accounting for the most minimal type of self-awareness entailed by (...) phenomenal consciousness. First, I clarify the main view endorsing this claim i.e. the Self-Presentational View of Consciousness and formulate the challenge from thought insertion. After, I offer a systematic evaluation of all the strategies used by the advocates of this view to deal with this challenge. Finally, I conclude that most of these strategies are unsatisfactory for they rest in unwarranted premises, imprecisions about the agentive nature of cognitive experiences, and especially, lack of distinction between the different ways in which subjects can become aware of their own thoughts.

The study aims to expose vulnerabilities of the subject-object paradigm in modern philosophy. The article concentrates upon ontological limitations of the concept of a subject and changing the status of an object in subject-object relations in the context of changing characteristics of the object existence. Scientific novelty of the work lies in identifying points of ontological stability and limitations of the subject concept, which could be used in its further theoretical development. As a result of the research, the aspects necessary, (...) from the author’s viewpoint, for building a theoretical model of the modern subject, which would be based on ontological symbiosis of subjective and objective characteristics, are determined.

How all philosophical explanations of human consciousness and the fundamental structure of the cosmos are bizarre—and why that’s a good thing Do we live inside a simulated reality or a pocket universe embedded in a larger structure about which we know virtually nothing? Is consciousness a purely physical matter, or might it require something extra, something nonphysical? According to the philosopher Eric Schwitzgebel, it’s hard to say. In The Weirdness of the World, Schwitzgebel argues that the answers to these fundamental (...) questions lie beyond our powers of comprehension. We can be certain only that the truth—whatever it is—is weird. Philosophy, he proposes, can aim to open—to reveal possibilities we had not previously appreciated—or to close, to narrow down to the one correct theory of the phenomenon in question. Schwitzgebel argues for a philosophy that opens. According to Schwitzgebel’s “Universal Bizarreness” thesis, every possible theory of the relation of mind and cosmos defies common sense. According to his complementary “Universal Dubiety” thesis, no general theory of the relationship between mind and cosmos compels rational belief. Might the United States be a conscious organism—a conscious group mind with approximately the intelligence of a rabbit? Might virtually every action we perform cause virtually every possible type of future event, echoing down through the infinite future of an infinite universe? What, if anything, is it like to be a garden snail? Schwitzgebel makes a persuasive case for the thrill of considering the most bizarre philosophical possibilities. (shrink)

It is often claimed that a minimal form of self-awareness is constitutive of our conscious experience. Some have considered that such a claim is plausible for our ordinary experiences but false when considered unrestrictedly on the basis of the empirical evidence from altered states. In this paper I want to reject such a reasoning. This requires, first, a proper understanding of a minimal form of self-awareness – one that makes it plausible that minimal self-awareness is part of our ordinary experiences. (...) I will argue that it should be understood as Perspectival First-Person Awareness : a non-conceptual identification-free self-attribution that defines the first-person perspective for our conscious experience. I will offer a detailed characterization of PFP-Awareness in semantic and epistemological terms. With this tool in hand, I will review the empirical literature on altered states. I will focus on psychedelics, meditation and dreams, as they have been claimed to present the clearest cases in favor of a radical disruption of self-awareness. I will show that the rejection of the idea that minimal self-awareness is constitutive of our experience on the basis of this evidence is unfounded, for two main reasons. First, although there are good grounds to think that some forms of self-awareness that typically accompany our ordinary experiences are compromised, they do not support the claim that PFP-Awareness is absent. Secondly, the reports that could make us think of a radical disruption of self-awareness are most probably due to a confirmation bias – and hence we should mistrust them – derived from the expectations and metaphysical views of their subjects.

Research on the specific features of daydreaming compared with mind-wandering and night dreaming is a neglected topic in the philosophy of mind and the cognitive neuroscience of spontaneous thought. The extant research either conflates daydreaming with mind-wandering (whether understood as task-unrelated thought, unguided attention, or disunified thought), characterizes daydreaming as opposed to mind-wandering (Dorsch, 2015), or takes daydreaming to encompass any and all “imagined events” (Newby-Clark & Thavendran, 2018). These dueling definitions obstruct future research on spontaneous thought, and are insufficiently (...) precise to guide empirical studies. They also fail to illuminate the phenomenal core of daydreaming, namely, its dreamlike qualities. Although daydreaming is related to both mind-wandering and narrative imagination, it is not reducible to either. We argue that daydreams are experiences of spontaneous, immersive imagination in the waking state. The main task of our investigation is to distinguish daydreaming, conceptually and phenomenologically, from mind-wandering, on the one hand, and night dreaming, on the other. Although daydream experiences can vary widely, we distinguish prototypical experiences of daydreaming from adjacent imaginative activity, including fleeting imagery and “focused daydreaming,” or crafted visualization. We consider our phenomenological analysis as preparatory work for conceptually distinguishing different spontaneous and imaginative states so that they can be investigated accordingly with questionnaires and qualitative methods. We argue that precision about the phenomenal character of daydreaming can guide neurophenomenological investigations, help delimit studies on individual variance in daydreaming features, and identify differences among daydreaming, mind-wandering, and night dreaming conceptually and phenomenologically, and possibly eventually in terms of neural correlates.

As a topic in the philosophy of psychology, dreaming is a fascinating, diverse, and severely underdeveloped area of study. The topic excites intense public interest in its own right, while also challenging our confidence that we know what the words “conscious” and “consciousness” mean. So dreaming should be at the forefront of our interdisciplinary investigations: theories of mind which fail to address the topic are incomplete. This chapter illustrates the tight links between conceptual and empirical issues by highlighting surprisingly deep (...) disagreements among leading dream scientists over what might seem basic aspects of their topic.

Many authors claim that being conscious constitutively involves being self-conscious, or conscious of oneself. This claim appears to be threatened by reports of `selfless' episodes, or conscious episodes lacking self-consciousness, recently described in a number of pathological and nonpathological conditions. However, the credibility of these reports has in turn been challenged on the following grounds: remembering and reporting a past conscious episode as an episode that one went through is only possible if one was conscious of oneself while undergoing it. (...) Call this the Memory Challenge. This paper argues that the Memory Challenge fails to undermine the credibility to reports of selfless episodes, because it rests on problematic assumptions about episodic memory. The paper further argues that we should distinguish between several kinds of self-representation that may be involved in the process of episodic remembering, and that once we do so, it is no longer mysterious how one could accurately remember and report a selfless episode as an episode that one went through. Thus, we should take reports of this kind seriously, and view them as credible counter-examples to the claim that consciousness constitutively involves self-consciousness. (shrink)

In this paper, I claim that the personal/subpersonal distinction is first and foremost a distinction between two kinds of psychological theory or explanation: it is only in this form that we can understand why the distinction was first introduced, and how it continues to earn its keep. I go on to examine the different ontological commitments that might lead us from the primary distinction between personal and subpersonal explanations to a derivative distinction between personal and subpersonal states. I argue that (...) on one of the most common metaphysical interpretations of the explanatory distinction, talk of a distinction between personal and subpersonal states simply makes no sense. When people insist on applying the personal/subpersonal terminology to psychological states, I allow that they are often making a genuine distinction, but one that it is best understood in terms of Stich's (1978) distinction between doxastic and subdoxastic states. I end the paper by considering some other common misinterpretations of the personal/subpersonal distinction, such as those involving consciousness, normativity, or autonomy. (shrink)

This paper critically tracks the impact of the development of the machine consciousness paradigm from the incredulity of the 1990s to the structuring of the turn of this century, and the consolidation of the present time which forms the basis for guessing what might happen in the future. The underlying question is how this development may have changed our understanding of consciousness and whether an artificial version of the concept contributes to the improvement of computational machinery and robots. The paper (...) includes some suggestions for research that might be profitable and others that may not be. (shrink)

The question about the potential for consciousness of artificial systems has often been addressed using thought experiments, which are often problematic in the philosophy of mind. A more promising approach is to use real experiments to gather data about the correlates of consciousness in humans, and develop this data into theories that make predictions about human and artificial consciousness. A key issue with an experimental approach is that consciousness can only be measured using behavior, which places fundamental limits on our (...) ability to identify the correlates of consciousness. This paper formalizes these limits as a distinction between type I and type II potential correlates of consciousness (PCCs). Since it is not possible to decide empirically whether type I PCCs are necessary for consciousness, it is indeterminable whether a machine that lacks neurons or hemoglobin, for example, is potentially conscious. A number of responses have been put forward to this problem, including suspension of judgment, liberal and conservative attribution of the potential for consciousness and a psychometric scale that models our judgment about the relationship between type I PCCs and consciousness.

Phenomenology and analytical philosophy share a number of common concerns, and it seems obvious that analytical philosophy can learn from phenomenology, just as phenomenology can profit from an exchange with analytical philosophy. But although I think it would be a pity to miss the opportunity for dialogue that is currently at hand, I will in the following voice some caveats. More specifically, I wish to discuss two issues that complicate what might otherwise seem like rather straightforward interaction. The first issue (...) concerns the question of whether the current focus on the first-person perspective might have a negative side-effect by giving us a slanted view of what subjectivity amounts to. The second issue concerns the question of whether superficial similarities in the descriptive findings might actually conceal some rather deep-rooted differences in the systematic use these findings serve. (shrink)

Psychedelic ingestion and meditative practice are both ancient methods for altering consciousness that became widely known in Western society in the second half of the 20th century. Do the similarities begin and end there, or do these methods – as many have claimed over the years – share some deeper common elements? In this chapter I take a neurophilosophical approach to this question and argue that there are, indeed, deeper commonalities. Recent empirical studies show that psychedelics and meditation modulate overlapping (...) brain networks involved in the sense of self, salience, and attention; moreover, psychedelics can occasion lasting increases in “mindfulness-related capacities” for taking a non-reactive stance on one’s inner experience (e.g. Sampedro et al. 2017). The self-binding theory of psychedelic ego dissolution (Letheby and Gerrans 2017) offers a plausible explanation of these findings: by disrupting self-related beliefs implemented in high-level cortical networks, both psychedelics and meditation can “unbind” mental contents from one’s self-model, moving these contents along the continuum from phenomenal transparency to opacity (cf. Metzinger 2003). In other words, both psychedelics and meditation can expose and weaken our foundational beliefs about our own identity, allowing us to disidentify with these beliefs and see them as “just thoughts”. There are connections between these ideas and recent arguments suggesting that psychedelic use may have epistemic benefits consistent with philosophical naturalism (Letheby 2015, 2016, 2019). I conclude with a proposal: these connections may help in thinking about the putative epistemic benefits of meditation practice from a naturalistic perspective. (shrink)

In Explaining Attitudes, Baker argues that we should treat our everyday practices as relevant to metaphysical debates, resulting in a stance of realism with respect to intentional explanations. In this chapter I will argue that if one is going to be a practical realist about anything, it should be the self, or subject of attention. I will use research on attention combined with the stance of practical realism to argue in favor of a substantive self. That is, I will present (...) an account of the self that directs and controls attention, in line with our everyday view of the self. I will contrast this account with what I call the “illusion view,” which presents the self and its apparent causal power in the case of attention as an illusion. My account of the self will make use of several of Baker's ideas, including non-reductive materialism and broad supervenience. (shrink)

An emerging consensus in cognitive science views the biological brain as a hierarchically-organized predictive processing system that relies on generative models to predict the structure of sensory information. Such a view resonates with a body of work in machine learning that has explored the problem-solving capabilities of hierarchically-organized, multi-layer (i.e., deep) neural networks, many of which acquire and deploy generative models of their training data. The present chapter explores the extent to which the ostensible convergence on a common neurocomputational architecture (...) (centred on predictive processing schemes, hierarchical organization, and generative models) might provide inroads into the problem of digital immortality. In contrast to approaches that seek to recapitulate the connectomic microstructure of the human brain, the present chapter advocates an approach that is rooted in the use of machine learning algorithms. The claim is that a future form of deep learning system could be used to acquire generative models of a given individual or (alternatively) the sensory data that is processed by the brain of a given individual during the course of their biological life. The differences between these two forms of digital immortality are explored, as are some of the options for digital resurrection. (shrink)

Clark and Chalmers propose that the mind extends further than skin and skull. If they are right, then we should expect this to have some effect on our way of knowing our own mental states. If the content of my notebook can be part of my belief system, then looking at the notebook seems to be a way to get to know my own beliefs. However, it is at least not obvious whether self-ascribing a belief by looking at my notebook (...) is a case of introspection the same way that knowing my non-extended beliefs is. Traditionally this sort of introspection is thought to be privileged and special in ways that the extended introspection case seems not to be. There is nothing privileged about looking at my notebook. Anyone could do it. The aim of the paper is to find out how to understand extended introspection and whether there is something privileged and special about knowing one’s own extended beliefs. Moreover, the notebook case has close analogs using twenty-first century technology. It seems possible to know our beliefs that are extended to smartphones, wearable technology or a cloud-based data store. First, I present the case of extended introspection. I then discuss whether it should be understood as ordinary introspection or as mind-reading. Both seem to be bad fits, which finally prompts an original account for extended introspection based on epistemic rules. (shrink)

In this chapter, I introduce phenomenology and phenomenological psychopathology by clarifying the kind of implicit experiences that phenomenologists are concerned with. In section one, I introduce the phenomenological concept of pre-reflective experience, focusing especially on its relation to the concept of implicit experience. In section two, I introduce the structure of pre-reflective self-consciousness, which has been studied extensively by both classical phenomenologists and contemporary phenomenological psychopathologists. In section three, I show how phenomenological psychopathologists rely on an account of pre-reflective self-consciousness (...) to better understand the experience of schizophrenia and I outline some of the methodological challenges that arise in this field of research. This introduction should facilitate critical engagement and collaboration between phenomenologists and researchers working across a variety of disciplines, including psychology, psychiatry, the cognitive sciences, and analytic philosophy of mind.

In his 1993 article ‘The Coming Technological Singularity: How to survive in the posthuman era’ the computer scientist Virnor Vinge speculated that developments in artificial intelligence might reach a point where improvements in machine intelligence result in smart AI’s producing ever-smarter AI’s. According to Vinge the ‘singularity’, as he called this threshold of recursive self-improvement, would be a ‘transcendental event’ transforming life on Earth in ways that unaugmented humans are not equipped to envisage. In this paper I argue Vinge’s idea (...) of a technologically led intelligence explosion is philosophically important because it requires us to consider the prospect of a posthuman condition succeeding the human one. What is the ‘humanity’ to which the posthuman is ‘post’? Does the possibility of a posthumanity presuppose that there is a ‘human essence’, or is there some other way of conceiving the human-posthuman difference? I argue that the difference should be conceived as a historically emergent disconnection between individuals, not in terms of the presence or lack of essential properties. I also suggest that these individuals should not be conceived in narrow biological terms but in ‘wide’ terms permitting biological, cultural and technological relations of descent between human and posthuman. Finally, I consider the ethical implications of this metaphysics of the posthuman. If, as I claim, the posthuman difference is not one between kinds but between individuals, we cannot specify its nature a priori but only a posteriori. Thus the only way to evaluate the posthuman condition would be to witness the emergence of posthumans. The implications of this are somewhat paradoxical. We are not currently in a position to evaluate the posthuman condition. Since there are no posthumans, the condition of posthumanity is not defined. However, posthumans could result from some iteration of our current technical activity, so we have an interest in understanding what they might be like. It follows that we have an interest in making or becoming posthumans. (shrink)

“Classic”, serotonergic psychedelic drugs such as LSD and psilocybin are the objects of renewed attention in science and psychiatry. A recent spate of research has produced evidence that psychedelics might be safe and effective adjuncts to the treatment of mood and addictive disorders, agents of positive psychological change in healthy subjects, and valuable tools for studying the neural mechanisms of perception and cognition. This chapter surveys three philosophical debates that have arisen in response to this “renaissance” of psychedelic research. The (...) first concerns the mechanisms of psychedelic-assisted psychotherapy (“psychedelic therapy”): How, exactly, does psychedelic administration in controlled conditions cause lasting psychological benefits? The second concerns the implications of psychedelic research for the philosophy of mind: Does psychedelic evidence show that there can be conscious mental states lacking all forms of self-consciousness? The third concerns the epistemic status of the psychedelic state: Is it possible that certain kinds of knowledge, or other epistemic benefits, could be gained by undergoing a psychedelic experience?

Emotion is conceptualised as an emergent, dynamic process based on an individual's subjective appraisal of significant events. It is argued that theoretical models of emotion need to propose an architecture that reflects the essential nature and functions of emotion as a psychobiological and cultural adaptation mechanism. One proposal for such a model and its underlying dynamic architecture, the component process model, is briefly sketched and compared with some of its major competitors. Recent empirical evidence in support of the model is (...) reviewed. Special emphasis is given to the dynamic aspect of emotion processes, in particular the sequence of appraisal checks and the synchronisation of response systems, as well as the capacity of the model to predict individual differences in emotional responding.

In this book, William Brant inquires how violence is reduced. Social causes of violence are exposed. War, sexual domination, leadership, propagandizing and comedy are investigated. Legal systems are explored as reducers and implementers of violence and threats.

In this paper, we put forward an interdisciplinary framework describing different levels of self-representations, namely non-conceptual, conceptual and propositional self-representations. We argue that these different levels of self-representation are differently affected by cultural upbringing: while propositional self-representations rely on “theoretical” concepts and are thus strongly influenced by cultural upbringing, non-conceptual self-representations are uniform across cultures and thus universal. This differentiation offers a theoretical specification of the distinction between an independent and interdependent self-construal put forward in cross-cultural psychology. Hence, this does (...) not only allow for a deeper understanding of different self-conceptions, but also for a formulation of new hypotheses regarding the cultural influence on self-representations. As one example, we will highlight the role of the proposed levels of self-representation for emotional experience and formulate some major implications of our interdisciplinary framework for future empirical research.

In recent years, the social dimensions of selfhood have been discussed widely. Can you be a self on your own or only together with others? Is selfhood a built-in feature of experience or rather socially constructed? Does a strong emphasis on the first-personal character of consciousness prohibit a satisfactory account of intersubjectivity or is the former rather a necessary requirement for the latter? These questions are explored in the following contribution.

If we want to assess whether or not a naturalized phenomenology is a desideratum or a category mistake, we need to be clear on precisely what notion of phenomenology and what notion of naturalization we have in mind. In the article I distinguish various notions, and after criticizing one type of naturalized phenomenology, I sketch two alternative takes on what a naturalized phenomenology might amount to and propose that our appraisal of the desirability of such naturalization should be more positive, (...) if we opt for one or both of the latter alternatives.

Can phenomenology contribute to the burgeoning science of consciousness? Dennett’s reply would probably be that it very much depends upon the type of phenomenology in question. In my paper I discuss the relation between Dennett’s heterophenomenology and the type of classical philosophical phenomenology that one can find in Husserl, Scheler and Merleau-Ponty. I will in particular be looking at Dennett’s criticism of classical phenomenology. How vulnerable is it to Dennett’s criticism, and how much of a challenge does his own alternative (...) constitute? I will argue that there are some rather marked differences between these two approaches to consciousness, but as I also hope to make clear, Dennett’s own account of where the differences are located is off target and ultimately based on a somewhat flawed conception of what classical phenomenology amounts to.

Review of Philosophy and Psychology has lately published a number of papers that in various ways take issue with and criticize my work on the link between consciousness, self-consciousness and selfhood. In the following contribution, I reply directly to this new set of objections and argue that while some of them highlight ambiguities in my work that ought to be clarified, others can only be characterized as misreadings.

Phantom limb experiences demonstrate an unexpected degree of fragility inherent in our self-perceptions. This is perhaps most extreme when congenitally absent limbs are experienced as phantoms. Aplasic phantoms highlight fundamental questions about the physiological bases of self-experience and the ontogeny of a physical, embodied sense of the self. Some of the most intriguing of these questions concern the role of mirror neurons in supporting the development of self–other mappings and hence the emergence of phantom experiences of congenitally absent limbs. In (...) this paper, we will examine the hypothesis that aplasic phantom limb experience is the result of an ontogenetic interplay between body schemas and mirror neuron activity and that this interplay is founded on embedding in a social context. Phantom limb experience has been associated with the persistence of subjective experience of a part of the body after deafferentation through surgical or traumatic removal. We maintain that limited association is inconsistent with the extent to which phantom limb experience is reported by aplasic individuals. (shrink)

In 1890 William James distinguished two understandings of the self, the self as “Me” and the self as “I”. This distinction has recently regained popularity in cognitive science, especially in the context of experimental studies on the underpinnings of the phenomenal self. The goal of this paper is to take a step back from cognitive science and attempt to precisely distinguish between “Me” and “I” in the context of consciousness. This distinction was originally based on the idea that the former (...) (“Me”) corresponds to the self as an object of experience (self as object), while the latter (“I”) reflects the self as a subject of experience (self as subject). I will argue that in most of the cases (arguably all) this distinction maps onto the distinction between the phenomenal self (reflecting self-related content of consciousness) and the metaphysical self (representing the problem of subjectivity of all conscious experience), and as such these two issues should be investigated separately using fundamentally different methodologies. Moreover, by referring to Metzinger’s theory of phenomenal self-models, I will argue that what is usually investigated as the phenomenal-“I” (following understanding of self-as-subject introduced by Wittgenstein) can be interpreted as object, rather than subject of experience, and as such can be understood as an element of the hierarchical structure of the phenomenal self-model. This understanding relates to recent predictive coding and free energy theories of the self and bodily self from cognitive neuroscience and philosophy. (shrink)

The paper proposes a minimal definition of dreaming in terms of immersive spatiotemporal hallucination (ISTH) occurring in sleep or during sleep–wake transitions and under the assumption of reportability. I take these conditions to be both necessary and sufficient for dreaming to arise. While empirical research results may, in the future, allow for an extension of the concept of dreaming beyond sleep and possibly even independently of reportability, ISTH is part of any possible extension of this definition and thus is a (...) constitutive condition of dreaming. I also argue that the proposed ISTH model of dreaming, in conjunction with considerations on the epistemic relationship between dreaming and dream reports, raises important questions about the extent to which dreams typically involve a detailed body representation—an assumption that plays an important role in philosophical work on dreaming. As a commonly accepted definition of dreaming is lacking in current dream research, the ISTH model, which integrates conceptual analysis and epistemological considerations with results from empirical research, is an important contribution to this field. By linking dreaming to felt presence, full-body illusions, and autoscopic phenomena such as out-of-body experiences in wakefulness and in the hypnagogic state, the ISTH model of dreaming also helps integrate dream research, both theoretically and experimentally, with the study of other altered states of consciousness involving hallucinations. It makes straightforward and investigable predictions by claiming that all of these experiences have amodal spatiotemporal hallucinations as their common denominator. Finally, it is theoretically relevant for the philosophical discussion on minimal phenomenal selfhood. (shrink)

In this paper, I discuss the relationship between bodily experiences in dreams and the sleeping, physical body. I question the popular view that dreaming is a naturally and frequently occurring real-world example of cranial envatment. This view states that dreams are functionally disembodied states: in a majority of dreams, phenomenal experience, including the phenomenology of embodied selfhood, unfolds completely independently of external and peripheral stimuli and outward movement. I advance an alternative and more empirically plausible view of dreams as weakly (...) phenomenally-functionally embodied states. The view predicts that bodily experiences in dreams can be placed on a continuum with bodily illusions in wakefulness. It also acknowledges that there is a high degree of variation across dreams and different sleep stages in the degree of causal coupling between dream imagery, sensory input, and outward motor activity. Furthermore, I use the example of movement sensations in dreams and their relation to outward muscular activity to develop a predictive processing account. I propose that movement sensations in dreams are associated with a basic and developmentally early kind of bodily self-sampling. This account, which affords a central role to active inference, can then be broadened to explain other aspects of self- and world-simulation in dreams. Dreams are world-simulations centered on the self, and important aspects of both self- and world-simulation in dreams are closely linked to bodily self-sampling, including muscular activity, illusory own-body perception, and vestibular orienting in sleep. This is consistent with cognitive accounts of dream generation, in which long-term beliefs and expectations, as well as waking concerns and memories play an important role. What I add to this picture is an emphasis on the real-body basis of dream imagery. This offers a novel perspective on the formation of dream imagery and suggests new lines of research. (shrink)

In this paper, we address the different ways in which dream research can contribute to interdisciplinary consciousness research. As a second global state of consciousness aside from wakefulness, dreaming is an important contrast condition for theories of waking consciousness. However, programmatic suggestions for integrating dreaming into broader theories of consciousness, for instance by regarding dreams as a model system of standard or pathological wake states, have not yielded straightforward results. We review existing proposals for using dreaming as a model system, (...) taking into account concerns about the concept of modeling and the adequacy and practical feasibility of dreaming as a model system. We conclude that existing modeling approaches are premature and rely on controversial background assumptions. Instead, we suggest that contrastive analysis of dreaming and wakefulness presents a more promising strategy for integrating dreaming into a broader research context and solving many of the problems involved in the modeling approach.

I respond to Ned Block’s claim that it is ridiculous to suppose that consciousness is a cultural construction based on language and learned in childhood. Block is wrong to dismiss social constructivist theories of consciousness on account of it being ludicrous that conscious experience is anything but a biological feature of our animal heritage, characterized by sensory experience, evolved over millions of years. By defending social constructivism in terms of both Julian Jaynes’ behaviorism and J.J. Gibson’s ecological psychology, I draw (...) a distinction between the experience or what-it-is-like of nonhuman animals engaging with the environment and the secret theater of speechless monologue that is familiar to a linguistically competent human adult. This distinction grounds the argument that consciousness proper should be seen as learned rather than innate and shared with nonhuman animals. Upon establishing this claim, I defend the Jaynesian definition of consciousness as a social–linguistic construct learned in childhood, structured in terms of lexical metaphors and narrative practice. Finally, I employ the Jaynesian distinction between cognition and consciousness to bridge the explanatory gap and deflate the supposed hard problem of consciousness. (shrink)

We argue that the projective geometrical component of the Projective Consciousness Model can account for key aspects of pre-reflective self-consciousness and can relate PRSC intelligibly to another signal feature of subjectivity: perspectival character or point of view. We illustrate how the projective geometrical versions of the concepts of duality, reciprocity, polarity, closedness, closure, and unboundedness answer to salient aspects of the phenomenology of PRSC. We thus show that the same mathematics that accounts for the statics and dynamics of perspectival character (...) also accounts for PRSC. More generally, we argue that introducing higher-level geometrical concepts into the theory of PRSC, and into the theory of consciousness broadly, as the PCM does, promises to break longstanding theoretical impasses and dialectical stalemates.

The Predictive Mind by Jakob Hohwy is the first monograph to address the philosophical significance of what Hohwy calls the prediction error minimization framework. The central claim of the book is that, on a conceptual level, perception, action, and cognition can be understood by reference to a single principle: prediction error minimization. The corresponding empirical hypothesis is that the brain implements a hierarchical generative model that generates predictions about sensory inputs and their hidden causes. When sensory signals arrive, only their (...) divergence from the predictions has to be further processed. The general strategy of using predictions derived from generative models to compress and transmit information is also known as predictive coding.Perception is thus not construed as a purely bottom–up process, but.

Some authors argue that phenomenal unity can be grounded in the attentional structure of consciousness, which endows conscious states with at least a foreground and a background. Accordingly, the phenomenal character of part of a conscious state comprises a content aspect and a structural aspect. This view presents the concern that such a structure does not bring about phenomenal unity, but phenomenal segregation, since the background is separated from the foreground. I argue that attention can still lead to a form (...) of phenomenal unity that connects the foreground with the background. Experiencing oneself as controlling the focus of attention can, at least occasionally, bring about an experienced connection between the attentional foreground and the attentional background of a conscious experience.

This paper is premised on the idea that cyberspace permits the user a degree of somatic flexibility?a means of transcending the physical body but not, importantly, embodiment. Set within a framework of progressive embodiment (the assumption that individuals seek to exploit somatic flexibility so as to extend the boundaries of their own embodiment?what we call the supermorphic persona), we examine the manner of this progression. Specifically, to what extent do components of embodiment?the self-as-object, the phenomenal self, and the body-schema?find authentic (...) expression within cyberspace? In addition, we also consider ways in which the issue of authenticity might impact on the psychological well being of the individual who seeks to transcend domains and present their supermorphic persona on- and offline.

Recent discussions in cognitive science and the philosophy of mind have defended a theory according to which we live in a virtual world akin to a computer simulation, generated by our brain. It is argued that our brain creates a model world from a variety of stimuli; this model is perceived as if it was external and perception-independent, even though it is neither of the two. The view of the mind, brain, and world, entailed by this theory has some peculiar (...) consequences which have rarely been explored in detail. This paper sets out virtual world theory and relates it to various central philosophical problems, the role of the perceiver and the problem of the existence of the external world ). The second part suggests three interpretations of virtual world theory, two familiar ones and a somewhat less familiar one. The remainder of the paper argues that the irrealist interpretation is the one we should adopt. (shrink)

An argument is developed for the conclusion that certain neurological conditions and disorders are directly relevant for understanding the self?'s embodiment and the ownership of conscious experience enjoyed by such an embodied self. Since these neurological conditions and disorders provide evidence that there can be shifts of, and compromises to, ownership, they help identify neural substrates and realizers of such ownership. However, even if recent neuroimaging and neuropsychological nominees for neural substrates of ownership unity are core realizers of ownership, they (...) are not its total realizers. Implications of the distinction between core and total realizers are discussed. (shrink)

Advances in artificial intelligence, as well as its increased presence in everyday life, have brought the emergence of many new phenomena, including an intriguing appearance of what seems to be a variant of body dysmorphic disorder, coined “Snapchat dysmorphia”. Body dysmorphic disorder is a DSM-5 psychiatric disorder defined as a preoccupation with one or more perceived defects or flaws in physical appearance that are not observable or appear slight to others. Snapchat dysmorphia is fueled by automated selfie filters that reflect (...) unrealistic sociocultural standard. In this paper, we discuss how body dysmorphic disorder and related body image distortions could arise, using the conceptual resources provided by the active inference framework. We suggest that these disorders involve dysfunctional self-modelling which entails maladaptive internalization of sociocultural preferences during adolescent identity formation. Identity formation is hereby described as cycles of interpersonal active inference that arbitrate between identity exploration and commitment. We propose that impaired self-modelling is unable to reduce interpersonal uncertainty during identity exploration, which, over time, degenerates into uncontrollable epistemic habits that isolate the body image from corrective sensory evidence. In light of these insights, we subsequently explore some of the consequences of image-centered social media platforms on the identity formation process. We conclude that heightened interpersonal uncertainty in this novel context could precipitate the onset of body dysmorphic disorder and related body image distortions, particularly when selfie filters are involved.
