Despite the large interest in the human ability to perceive space present in neuroscience, cognitive science and psychology, as well as philosophy of mind, the issues regarding egocentric space representation received relatively less attention. In this paper I take up a unique phenomenon related to this faculty: the “spatial purport” of perceptual experiences. The notion was proposed by Rick Grush to describe the subjective, qualitative aspects of egocentric representations of spatial properties and relations. Although Grush offered an explanation of the (...) mechanism giving rise to appearance of spatial purport, his model had considerable shortcomings. In the paper I thoroughly analyze both the notion of spatial purport and Grush’s explanation of the mechanism at its core in order to develop his theory using the insights provided by the predictive processing theory of mind, and more particularly by the active inference framework. The extended account I offer, named Predictive and Hierarchical Skill Theory, explains phenomena that escaped Grush’s model and furthers the research on egocentric space representation from the perspective of both neuroscience and philosophy of mind.

This paper presents a version of neurophenomenology based on generative modelling techniques developed in computational neuroscience and biology. Our approach can be described as _computational phenomenology_ because it applies methods originally developed in computational modelling to provide a formal model of the descriptions of lived experience in the phenomenological tradition of philosophy (e.g., the work of Edmund Husserl, Maurice Merleau-Ponty, etc.). The first section presents a brief review of the overall project to naturalize phenomenology. The second section presents and evaluates (...) philosophical objections to that project and situates our version of computational phenomenology with respect to these projects. The third section reviews the generative modelling framework. The final section presents our approach in detail. We conclude by discussing how our approach differs from previous attempts to use generative modelling to help understand consciousness. In summary, we describe a version of computational phenomenology which uses generative modelling to construct a computational model of the inferential or interpretive processes that best explain this or that kind of lived experience.

In order to understand Hegel's approach to philosophy, we need to ask why, and how, he reacts to the well-known criticism of German Romantics, like Novalis and Friedrich Schlegel, against philosophical system building in general, and against Kant's system in particular. Hegel's encyclopedic system is a topical ordering of categorically different ontological realms, corresponding to different conceptual forms of representation and knowledge. All in all it turns into a systematic defense of Fichte's doctrine concerning the primacy of us as actors (...) with respect to any knowledge claim or scientific theory. Hegel's limitations of the principle of causality and of the possibility of using mathematical methods in science show, in fact, how a merely compatibilist solution of Kant's third antinomy can be overcome.

We propose a view of embodied representations that is alternative to both symbolic/linguistic approaches and purely sensorimotor views of cognition, and can account for procedural and declarative knowledge manipulation. In accordance with recent evidence in cognitive neuroscience and psychology, we argue that anticipatory and simulative mechanisms, which arose during evolution for action control and not for cognition, determined the first form of representational content and were exapted for increasingly sophisticated cognitive uses. In particular, procedural and declarative forms of knowledge can (...) be explained, respectively, in terms of on-line sensorimotor anticipation and off-line simulations of potential actions, which can give access to tacit knowledge and make it explicit. That is, mechanisms that evolved for the on-line prediction of the consequences of one's own actions (i.e. forward models) determine a (procedural) form of representation, and became exapted for off-line use. They can therefore be used to produce (declarative) knowledge of the world, by running a simulation of the action that would produce the relevant information. We conclude by discussing how embodied representations afford a form of internal manipulation that can be described as internalized situated action. (shrink)

Within the philosophy of mind, consciousness is currently understood as the expression of one or other cognitive modality, either intentionality , transparency , subjectivity or reflexivity . However, neither intentionality, subjectivity nor transparency adequately distinguishes conscious from nonconscious cognition. Consequently, the only genuine index or defining characteristic of consciousness is reflexivity, the capacity for autonoetic or self-referring, self-monitoring awareness. But the identification of reflexivity as the principal index of consciousness raises a major challenge in relation to the cognitive mechanism responsible (...) for operationalizing such a reflexive state. Current reliance by higher-order and intrinsic self-representational theories on self-representing data structures to achieve reflexive self-awareness is highly problematic, suggesting a solution in terms of a self-referential processing regime.

Bering's argument that human beings are endowed with a cognitive system dedicated to forming illusory representations of psychological immortality relies on the claim that children's beliefs in the afterlife are not the result of religious teaching. We suggest four reasons why this claim is unsatisfactory.

The fictionalist paradigm is introduced, and differentiated from other paradigms, using the Lincoln & Guba template. Following an initial overview, the axioms of fictionalism are delineated by reference to standard metaphysical categories: the nature of reality, the relationship between knower and known, the possibility of generalization, the possibility of causal linkages, and the role of values in inquiry. Although a paradigm's ‘basic beliefs’ are arbitrary and can be assumed for any reason, in this paper the fictionalist axioms are supported with (...) philosophical considerations, and the key differences between fictionalism, positivism, and constructivism are briefly explained. Paradigm characteristics are then derived, focusing particularly on the methodological consequences. Towards the end of the paper, various objections and misunderstandings are discussed. (shrink)

Searle suggests biological naturalism as a solution to the mind-brain problem that escapes traditional terminology with its seductive pull towards either dualism or materialism. We reconstruct Searle's argument and demonstrate that it needs additional support to represent a position truly located between dualism and materialism. The aim of our paper is to provide such an additional argument. We introduce the concept of "autoepistemic limitation" that describes our principal inability to directly experience our own brain as a brain from the first-person (...) perspective. The neglect of the autoepistemic limitation leads to inferences from epistemic properties to ontological features - we call this "epistemic-ontological inference." Searle attempts to avoid such epistemic-ontological inference but does not provide a sufficient argument. Once the autoepistemic limitation is considered, epistemic-ontological inference can be avoided. As a consequence, one can escape traditional terminology with its seductive pull towards either dualism or materialism. (shrink)

ABSTRACT The manifest fact of experiential unity—namely, that a single experience often seems to be composed of multiple features and multiple objects—was lodged as a key objection to the Buddhist no-self view by Nyāya philosophers in the classical Indian tradition. We revisit the Nyāya-Buddhist debate on this issue. The early Nyāya experiential unity arguments depend on diachronic unification of experiences in memory, but later Nyāya philosophers explicitly widened the scope to incorporate new unity arguments that invoke synchronic unification in experiences. (...) We argue that classical responses to this objection in the Buddhist traditions are not satisfactory. We offer a new solution on behalf of the Buddhists, with some help from cognitive sciences. We argue that there are different kinds of experiential unity and that, once we distinguish between these kinds, the Nyāya argument becomes difficult to sustain. (shrink)

The article examines epistemological and ontological underpinnings of reasearch performed by means of magnetic resonance imaging and functional magnetic resonance imaging. It takes as its guiding line the important distinction between instruments and apparatuses drawn by Rom Harré. According to Harré, instruments such as barometers or thermometers do not cause the states they measure into existence. Apparatuses, in contradistinction, cause material states into existence to begin with, whereby theses states are subsequently processed according to suitable methods. Thus, when the objects (...) of examination are subjected to 2 or more Tesla in fMRI, a strength of magnetic field never occuring in earthly nature, technical means literally create the states to be examined. Close examination of the functioning of MRI and fMRI indicates that brain states, e.g., are not simply read, or perceived as degrees of temperature are read on scale. Hence, one does not see any mental funtion when looking at fMRI outputs, for the visible output has been semantically processed on the basis of invisible quantum mechanical processes that have undergone translations into digital data caused by the fMRI device itself.

Scientific theories of consciousness identify its contents with the spatiotemporal structure of neural population activity. We follow up on this approach by stating and motivating Dynamical Emergence Theory, which defines the amount and structure of experience in terms of the intrinsic topology and geometry of a physical system’s collective dynamics. Specifically, we posit that distinct perceptual states correspond to coarse-grained macrostates reflecting an optimal partitioning of the system’s state space—a notion that aligns with several ideas and results from computational neuroscience (...) and cognitive psychology. We relate DET to existing work, offer predictions for empirical studies, and outline future research directions. (shrink)

In Cognitive science and philosophy of consciousness, the explanatory gap, following Joseph Levine, refers to the unintelligible link between our conscious mental life and its corresponding objective physical explanation; the gap in our understanding of how consciousness is related to a physical or a physiological substrate :354–361, 1983). David Chalmers holds the explanatory gap as the evidence for a form of metaphysical dualism between consciousness and physical reality. On the other hand, McGinn takes it as an epistemic rather than an (...) ontological gap. Considering the recent advances in neuroscience, however, the reductionist approaches have become replete, which attempt to reduce consciousness and subjectivity to neurobiological accounts. On this view, consciousness mirrors the brain mechanisms, and the self is formulated as an illusory product or construct of neuronal processes. Thomas Fuchs, who is committed to embodied and enactive approaches toward cognition, in Ecology of the Brain, espouses an enactive-ecological perspective concerning the problem of the explanatory gap. He develops an account of human’s life in its dual aspects of the living body and lived body which, on the one hand, defies the ontological dualism and, on the other hand, avoids drifting towards any form of reductionism. Often, the ontologically monistic approaches to the explanatory gap have inclined to a form of reductionism because they conceive consciousness as either identical with its physiological substrate or caused by it, where in both cases, consciousness is claimed to be explainable within the framework of physicalism. Fuchs, however, defends an ontological monism which remains irreconcilable with reductionism. In his account of dual aspects, there is no interaction or impact between the sphere of subjectivity and nature; however, these two aspects imply one another. In this essay, I will develop the philosophical justification of the above reformulation of the mind–body problem and employing the analogy of light will canvass the paradoxical relationship between dual aspects in a phenomenological framework.

This paper takes a new look at an old question: what is the human self? It offers a proposal for theorizing the self from an enactive perspective as an autonomous system that is constituted through interpersonal relations. It addresses a prevalent issue in the philosophy of cognitive science: the body-social problem. Embodied and social approaches to cognitive identity are in mutual tension. On the one hand, embodied cognitive science risks a new form of methodological individualism, implying a dichotomy not between (...) the outside world of objects and the brain-bound individual but rather between body-bound individuals and the outside social world. On the other hand, approaches that emphasize the constitutive relevance of social interaction processes for cognitive identity run the risk of losing the individual in the interaction dynamics and of downplaying the role of embodiment. This paper adopts a middle way and outlines an enactive approach to individuation that is neither individualistic nor disembodied but integrates both approaches. Elaborating on Jonas’ notion of needful freedom it outlines an enactive proposal to understanding the self as co-generated in interactions and relations with others. I argue that the human self is a social existence that is organized in terms of a back and forth between social distinction and participation processes. On this view, the body, rather than being identical with the social self, becomes its mediator. (shrink)

In recent years, the scientific study of meditation and psychedelic drugs has seen remarkable developments. The increased focus on meditation in cognitive neuroscience has led to a cross-cultural classification of standard meditation styles validated by functional and structural neuroanatomical data. Meanwhile, the renaissance of psychedelic research has shed light on the neurophysiology of altered states of consciousness induced by classical psychedelics, such as psilocybin and LSD, whose effects are mainly mediated by agonism of serotonin receptors. Few attempts have been made (...) at bridging these two domains of inquiry, despite intriguing evidence of overlap between the phenomenology and neurophysiology of meditation practice and psychedelic states. In particular, many contemplative traditions explicitly aim at dissolving the sense of self by eliciting altered states of consciousness through meditation, while classical psychedelics are known to produce significant disruptions of self-consciousness, a phenomenon known as drug-induced ego dissolution. In this article, we discuss available evidence regarding convergences and differences between phenomenological and neurophysiological data on meditation practice and psychedelic drug-induced states, with a particular emphasis on alterations of self-experience. While both meditation and psychedelics may disrupt self-consciousness and underlying neural processes, we emphasize that neither meditation nor psychedelic states can be conceived as simple, uniform categories. Moreover, we suggest that there are important phenomenological differences even between conscious states described as experiences of self-loss. As a result, we propose that self-consciousness may be best construed as a multidimensional construct, and that “self-loss,” far from being an unequivocal phenomenon, can take several forms. Indeed, various aspects of self-consciousness, including narrative aspects linked to autobiographical memory, self-related thoughts and mental time travel, and embodied aspects rooted in multisensory processes, may be differently affected by psychedelics and meditation practices. Finally, we consider long-term outcomes of experiences of self-loss induced by meditation and psychedelics on individual traits and prosocial behavior. We call for caution regarding the problematic conflation of temporary states of self-loss with “selflessness” as a behavioral or social trait, although there is preliminary evidence that correlations between short-term experiences of self-loss and long-term trait alterations may exist.

There is converging evidence that high doses of hallucinogenic drugs can produce significant alterations of self-experience, described as the dissolution of the sense of self and the loss of boundaries between self and world. This article discusses the relevance of this phenomenon, known as “drug-induced ego dissolution (DIED)”, for cognitive neuroscience, psychology and philosophy of mind. Data from self-report questionnaires suggest that three neuropharmacological classes of drugs can induce ego dissolution: classical psychedelics, dissociative anesthetics and agonists of the kappa opioid (...) receptor (KOR). While these substances act on different neurotransmitter receptors, they all produce strong subjective effects that can be compared to the symptoms of acute psychosis, including ego dissolution. It has been suggested that neuroimaging of DIED can indirectly shed light on the neural correlates of the self. While this line of inquiry is promising, its results must be interpreted with caution. First, neural correlates of ego dissolution might reveal the necessary neurophysiological conditions for the maintenance of the sense of self, but it is more doubtful that this method can reveal its minimally sufficient conditions. Second, it is necessary to define the relevant notion of self at play in the phenomenon of DIED. This article suggests that DIED consists in the disruption of subpersonal processes underlying the “minimal” or “embodied” self, i.e., the basic experience of being a self rooted in multimodal integration of self-related stimuli. This hypothesis is consistent with Bayesian models of phenomenal selfhood, according to which the subjective structure of conscious experience ultimately results from the optimization of predictions in perception and action. Finally, it is argued that DIED is also of particular interest for philosophy of mind. On the one hand, it challenges theories according to which consciousness always involves self-awareness. On the other hand, it suggests that ordinary conscious experience might involve a minimal kind of self-awareness rooted in multisensory processing, which is what appears to fade away during DIED.

This metatheoretical paper develops a list of new research targets by exploring particularly promising interdisciplinary contact points between empirical dream research and philosophy of mind. The central example is the MPS-problem. It is constituted by the epistemic goal of conceptually isolating and empirically grounding the phenomenal property of “minimal phenomenal selfhood,” which refers to the simplest form of self-consciousness. In order to precisely describe MPS, one must focus on those conditions that are not only causally enabling, but strictly necessary to (...) bring it into existence. This contribution argues that research on bodiless dreams, asomatic out-of-body experiences, and full-body illusions has the potential to make decisive future contributions. Further items on the proposed list of novel research targets include differentiating the concept of a “first-person perspective” on the subcognitive level; investigating relevant phenomenological and neurofunctional commonalities between mind-wandering and dreaming; comparing the functional depth of embodiment across dream and wake states; and demonstrating that the conceptual consequences of cognitive corruption and systematic rationality deficits in the dream state are much more serious for philosophical epistemology (and, perhaps, the methodology of dream research itself) than commonly assumed. The paper closes by specifying a list of potentially innovative research goals that could serve to establish a stronger connection between dream research and philosophy of mind. (shrink)

This metatheoretical paper investigates mind wandering from the perspective of philosophy of mind. It has two central claims. The first is that, on a conceptual level, mind wandering can be fruitfully described as a specific form of mental autonomy loss. The second is that, given empirical constraints, most of what we call “conscious thought” is better analyzed as a subpersonal process that more often than not lacks crucial properties traditionally taken to be the hallmark of personal-level cognition - such as (...) mental agency, explicit, consciously experienced goal-directedness, or availability for veto control. I claim that for roughly two thirds of our conscious life-time we do not possess mental autonomy (M-autonomy) in this sense. Empirical data from research on mind wandering and nocturnal dreaming clearly show that phenomenally represented cognitive processing is mostly an automatic, non-agentive process and that personal-level cognition is an exception rather than the rule. This raises an interesting new version of the mind-body problem: How is subpersonal cognition causally related to personal-level thought? More fine-grained phenomenological descriptions for what we called “conscious thought” in the past are needed, as well as a functional decomposition of umbrella terms like “mind wandering” into different target phenomena and a better understanding of the frequent dynamic transitions between spontaneous, task-unrelated thought and meta-awareness. In an attempt to lay some very first conceptual foundations for the now burgeoning field of research on mind wandering, the third section proposes two new criteria for individuating single episodes of mind-wandering, namely, the “self-representational blink” (SRB) and a sudden shift in the phenomenological “unit of identification” (UI). I close by specifying a list of potentially innovative research goals that could serve to establish a stronger connection between mind wandering research and philosophy of mind. (shrink)

To have an ontology is to interpret a world. In this paper we argue that the brain, viewed as a representational system aimed at interpreting our world, possesses an ontology too. It creates primitives and makes existence assumptions. It decomposes target space in a way that exhibits a certain invariance, which in turn is functionally significant. We will investigate which are the functional regularities guiding this decomposition process, by answering to the following questions: What are the explicit and implicit assumptions (...) about the structure of reality, which at the same time shape the causal profile of the brain's motor output and its representational deep structure, in particular of the conscious mind arising from it (its ''phenomenal output'')? How do they constrain high-level phenomena like conscious experience, the emergence of a first-person perspective, or social cognition? By reviewing a series of neuroscientific results and integrating them with a wider philosophical perspective, we will emphasize the contribution the motor system makes to this process. As it will be shown, the motor system constructs goals, actions, and intending selves as basic constituents of the world it interprets. It does so by assigning a single, unified causal role to them. Empirical evidence demonstrates that the brain models movements and action goals in terms of multimodal representations of organism-object-relations. Under a representationalist analysis, this process can be conceived of as an internal, dynamic representation of the intentionality-relation itself. We will show how such a complex form of representational content, once it is in place, can later function as a functional building block for social cognition and for a more complex, consciously experienced representation of the first-person perspective as well.

A representationalist analysis of strong first-person phenomena is developed (Baker 1998), and it is argued that conscious, cognitive self-reference can be naturalized under this representationalist analysis. According to this view, the phenomenal first-person perspective is a condition of possibility for the emergence of a cognitive first-person perspective. Cognitive self-reference always is reference to the phenomenal content of a transparent self-model. The concepts of phenomenal transparency and introspection are clarified. More generally, I suggest that the concepts of phenomenal opacity and phenomenal (...) transparency are interesting instruments for analyzing conscious, self-representational content, and that their relevance in understanding reflexive, i.e., cognitive subjectivity may have been overlooked in the past. (shrink)

This is the first in a series of instalments aiming at a minimal model explanation for conscious experience, taking the phenomenal character of “pure consciousness” or “pure awareness” in meditation as its entry point. It develops the concept of “minimal phenomenal experience” as a candidate for the simplest form of consciousness, substantiating it by extracting six semantic constraints from the existing literature and using sixteen phenomenological case-studies to incrementally flesh out the new working concept. One empirical hypothesis is that the (...) phenomenological prototype of “pure awareness”, to which all such reports refer, really is the content of a predictive model, namely, a Bayesian representation of tonic alertness. On a more abstract conceptual level, it can be described as a model of an unpartitioned epistemic space. (shrink)

In current trends in cognitive sciences, the discussion on body crosses the classical divide between the body and the self in terms of nature and function. Embodiment theories have helped to bring in the importance of the role of subjective experiences to understand cognition, and place the process of knowing in a cultural and social context. This article is a critique of the growing trend in cognitive sciences, particularly in affective neurosciences, and approaches, to reduce the experiential self to a (...) nonentity. It is shown that though the apparent goal is to highlight the inner qualitative nature of experience, what is happening in the background is a role reversal. The outer body becomes the inner self. The inner self becomes the outer body. The nature and functions of the self are founded on the body by theorizing embodiment as an alternate to neural reductionism. This article argues that one of the negative consequences of embodiment theories is that age-old concepts of freewill, character and moral choices become flimsy and fleeting in the process of embodying cognition.

According to the virtual self theory, selves are merely virtual entities. On this view, our self-representations do not refer to any concrete object and the self is a merely intentional entity. This contemporary version of the ‘no-self’ theory is driven by a number of psychological and philosophical considerations indicating that our representations of the self are pervasively inaccurate. I present two problems for VST. First, the case for VST fails to rule out a more moderate position according to which the (...) self exists but is systematically misrepresented by us. This position regards the self as a real entity that has illusory appearances, rather than as a hallucinated entity that has a merely intentional existence. Second, I suggest that this ‘illusion model’ of self-misrepresentation is preferable to VST. Advocates of VST must acknowledge the existence of an entity—typically the brain—that is the bearer of our misrepresentations of the self. I argue that, other things being equal, we should regard the bearer of our self-representations as the self, even if that entity diverges dramatically from the way we represent the self to be. So by acknowledging the existence of a bearer of self-representations, advocates of VST are in a poor position to deny the existence of the self. I conclude that VST not only fails to rule out the illusion model, but that we have prima facie reason to prefer the illusion model to VST. (shrink)

In the philosophical literature on consciousness and the mind-body problem, the conceivability argument against physicalism is usually taken to support a form of dualism between physicality and phenomenality. Usually, the discussion focuses on the qualitative character of experience, which is what the phenomenal feel of a given experience is like. By contrast, the subjective character of experience, or its individuation to a given first-person subject, tends to be set aside. The aim of this paper is to present a new and (...) more robust version of the conceivability argument for dualism that appeals to the subjective character of experience. Drawing on insights by philosophers in the phenomenological tradition, I conceptualise the first-person subjective character of experience as a transcendental condition of possibility for phenomenality that cannot be reduced to third-person facts about the physical world. Given this, the mind-body problem as it pertains to consciousness does not merely concern the inability of the set of physical facts about a brain state to capture the qualitative character of experience, but concerns the existential issue of why this brain state is accompanied by first-person subjectivity at all. This allows us to reconceive the conceivability argument in a way that presents a stronger case for dualism than the traditional version of the argument. (shrink)

Realism has been a central object of attention among analytical philosophers for some decades. Starting from analytical philosophy, the return of realism has spread into other contemporary philosophical traditions and given birth to new trends in current discussions, as for example in the debates about “new realism.” Discussions about realism focused on linguistic meaning, epistemology, metaphysics, theory of action and ethics. The implications for politics of discussion about realism in action theory and in ethics, however, are not much discussed.

This essay interrogates recent materialist monisms, be they based on contingency, eliminativism, or objective phenomenology, on account of their metaphilosophical ramifications. It is argued that certain dualities must be retained, at least nominally, in order to have any explanatory purchase and escape velocity from philosophical circularity. Dyads such as “spirit” and “matter,” “manifest” and “scientific,” “living” and “dead,” or even “illusion” and “reality” are given an immanentist reading that treats them as equal parts of the Real. Following this revisionary metaphysics (...) that reviews the meaning of such terms as optical realities, the matter–spirit couple is specifically used to explain why reality cannot appear as just one thing, even if only in virtue of the illusion of at least two things. The consequences for philosophical monisms of all types, and for anthropocentric thought in general, are then examined in the light of the ethical effects of recent attempts to explain every thing through one medium alone.

In the waking state, in the absence of meta-awareness, mind wandering with specific contents can lead to negative mood. Such negative mood can be incorporated into dreaming according to the continuity hypothesis of dreaming. In this paper we argue that in the presence of what we call ‘sustained phenomenal meta-awareness’, negative mood would not follow mind wandering in waking. Sustained phenomenal meta-awareness has a non-sensory, non-affective phenomenal character. It is essentially intransitive, prereflectively self-aware, non-propositional, non-conceptual and devoid of subject-object structure. (...) In other words, this unique kind of meta-awareness is non-representational. Evidence is then provided that such sustained phenomenal meta-awareness can be incorporated into the subsequent dream state as non-dual lucid dreaming in which, again, no negative mood would arise. Based on the latter observation, we have coined the term ‘mindful mind wandering’ and defined it as mind wandering in the presence of sustained phenomenal meta-awareness. We argue that not only does mindful mind wandering not lead to negative mood in waking, but also its incorporation into dreaming, as non-dual lucid dreaming, result in a state that is free of negative affection.

This article offers an analysis of intentionality for virtual objects and explores some of the ethical implications of this analysis. The main example which serves as a motivation for the article is the case of a Chinese gamer who, in 2005, committed murder in retaliation for the theft of a virtual object, the theft of his virtual dragon sabre. The intentional analysis reveals that the way in which we experience virtual objects shares a structural similarity with the way in which (...) we experience physical objects. Both virtual and physical objects are accessible through action and intersubjectively available. The final part of the article introduces three ethical points based on the intentional analysis. First, virtual objects can have the same ethical significance as physical objects. Second, it will be important to consider empirical results on the factors which influence one’s subjective level of immersion in the virtual world. Finally, the intentional analysis of virtual objects suggests specific questions for future research. (shrink)

This article is composed of three parts. In the first part of the article I take up a question raised by Susanna Siegel (Philosophical Review 115: 355–388, 2006a). Siegel has argued that subjects have the following anticipation: (PC) If S substantially changes her perspective on o, her visual phenomenology will change as a result of this change. She has left it an open question as to whether subjects anticipate a specific kind of change. I take up this question and answer (...) it in the affirmative. By appealing to a widely held view of perceptual content, the view that we represent ‘factual’ properties in perception, I argue that (PC) can be refined as follows: (PC’) If S substantially changes her perspective on o, her visual phenomenology will present different views of o’s factual properties. In the second part of the article I argue that (PC’) implies that there are cases in which normal perceivers have different perceptual content under identical viewing conditions. The differences in perceptual content are due to differences in the determinacy of visual anticipation. I draw the conclusion that perceptual content is rich in the sense that it includes a unique contribution from individual perceivers. In the final part of the article, I discuss some open issues regarding the way in which (PC’) relates to the personal/sub-personal distinction, empirical models, and the distinction between perception and cognition.

In this paper, I take up the problem of the self through bringing together the insights, while correcting some of the shortcomings, of Indo–Tibetan Buddhist and enactivist accounts of the self. I begin with an examination of the Buddhist theory of non-self ( anātman ) and the rigorously reductionist interpretation of this doctrine developed by the Abhidharma school of Buddhism. After discussing some of the fundamental problems for Buddhist reductionism, I turn to the enactive approach to philosophy of mind and (...) cognitive science. I argue that human beings, as dynamic systems, are characterized by a high degree of self-organizing autonomy. Therefore, human beings are not reducible to the more basic mental and physical events that constitute them. I critically examine Francisco Varela’s enactivist account of the self as virtual and his use of Buddhist ideas in support of this view. I argue, in contrast, that while the self is emergent and constructed, it is not merely virtual. Finally I sketch a Buddhist-enactivist account of the self. I argue for a non-reductionist view of the self as an active, embodied, embedded, self-organizing process—what the Buddhists call ‘I’-making ( ahaṃkāra ). This emergent process of self-making is grounded in the fundamentally recursive processes that characterize lived experience: autopoiesis at the biological level, temporalization and self-reference at the level of conscious experience, and conceptual and narrative construction at the level of intersubjectivity. In Buddhist terms, I will develop an account of the self as dependently originated and empty, but nevertheless real. (shrink)

The paper presents and discusses the “which-is-which content of handedness,” the meaning of left as left and right as right, as a possible candidate for the idea of a genuine embodied cognitive content. After showing that the Ozma barrier, the non-transferability of the meaning of left and right, provides a kind of proof of the non-descriptive, indexical nature of the which-is-which content of handedness, arguments are presented which suggest that the classical representationalist account of cognition faces a perplexing problem of (...) underdetermination of reference of left and right in the which-is-which sense. By way of contrast, no such problems occur in a framework were embodied contents are not mediated by some extra body model which carries the representational power, but are instead directly represented.

What makes psychedelic psychotherapy work? Is it the induction of psychedelic experience, with its distinct patterns of hallucinations and insights, or is it the neural ‘shakeup’ that moves the brain out of its regular mode of functioning and into a more disordered state? We consider the role that attention-related phenomenological changes play in psychedelic transformation and psychotherapy. We review Letheby’s account of psychedelic psychotherapy, which appeals to increases in phenomenal opacity as the central mechanism of psychotherapeutic transformation. We argue that (...) there is an alternative vehicle of psychedelic transformation that this account overlooks, involving radically transparent experiences. We outline the common kinds of phenomenal transparency shifts typical of psychedelic experiences, and argue that in many cases, such shifts are responsible for the psychotherapeutic benefits. This argument motivates an alternative approach to possible mechanisms of psychedelic self-transformation, and opens up a new venue of empirical research into the role of attention and phenomenology in psychedelic psychotherapy.

Elimination controversies are ubiquitous in philosophy and the human sciences. For example, it has been suggested that human races, hysteria, intelligence, mental disorder, propositional attitudes such as beliefs and desires, the self, and the super-ego should be eliminated from the list of respectable entities in the human sciences. I argue that eliminativist proposals are often presented in the framework of an oversimplified “phlogiston model” and suggest an alternative account that describes ontological elimination on a gradual scale between criticism of empirical (...) assumptions and conceptual choices.

Imagination and other forms of mental simulation allow us to live beyond the current immediate environment. Imagination that involves an experience of self further enables one to incorporate or utilize the contents of episodic simulation in a way that is of importance to oneself. However, the simulated self can be found in a variety of forms. The present study provides some empirical data to explore the various ways in which the self could be represented in observer-perspective imagination as well as (...) the potential limits on such representations. In observer-perspective imagination, the point of view or perspective is dissociated from the location of one’s simulated body. We have found that while there are different ways to identify with oneself in an observer-perspective imagination, the identification is rarely dissociated from first-person perspective in imagination. Such variety and limits pave the way for understanding how we identify with ourselves in imagination. Our results suggest that the first-person perspective is a strong attractor for identification. The empirical studies and analysis in this paper demonstrate how observer-perspective episodic simulation serves as a special case for research on identification in mental simulation, and similar methods can be applied in the studies of memory and future thinking.

Every episodic memory entails a sense of identity, which allows us to mentally travel through time. There is a special way by which the subject who is remembering comes into contact with the self that is embedded in the episodic simulation of memory: we can directly and robustly experience the protagonist in memory as ourselves. This paper explores what constitutes such experience in memory. On the face of it, the issue may seem trivial: of course, we are able to entertain (...) a sense of identity—the experience of our recollection structurally resembles our perception of the original event. However, given the phenomenon of observer memory, in which our visual perspective is decoupled from our embodied dimension, it is unclear whether it is the observing or the embodied one that is identified. This phenomenon is important not only in illustrating the complexity of identification but also in assessing how best to address it. In this paper, the issue is analyzed through concepts introduced from the literature on bodily self-consciousness. The potential approaches to addressing the issue of identification are examined, including the inheritance view, according to which the identification relies on the inheritance of mnemonic content from the original experience. I propose and argue for the self-simulation view, which suggests that what results in the experience of “I am this” in memory is the observing and the embodied dimensions as well as the relation between them, which enable different ways of projecting oneself into an episodic simulation.

In this paper, we address reports of “selfless” experiences from the perspective of active inference and predictive processing. Our argument builds upon grounding self-modelling in active inference as action planning and precision control within deep generative models – thus establishing a link between computational mechanisms and phenomenal selfhood. We propose that “selfless” experiences can be interpreted as cases in which normally congruent processes of computational and phenomenal self-modelling diverge in an otherwise conscious system. We discuss two potential mechanisms – within (...) the Bayesian mechanics of active inference – that could lead to such a divergence by attenuating the experience of selfhood: “self-flattening” via reduction in the depth of active inference and “self-attenuation” via reduction of the expected precision of self-evidence.

In two recent papers, I introduced the idea of embodied Rilkean movement knowledge and perception into the current philosophical debate on sports knowledge. In this paper, I offer a new analysis of how embodied movement knowledge and perception help us to identify and define movement consciousness. I develop a phenomenological account of embodied movement consciousness and show how it is closely linked to self-consciousness by generating anticipations and affordances that implicate pre-reflective self-awareness. I also expand Rowlands’ Rilkean memory notion to (...) include affective phenomenological properties that rely on the constitutive fault-lines between bodily material sensations and the ingrained recollections they are based on. From this perspective, embodied movement consciousness comprises empirical sensations that phenomenologically unfold as physical acts grounded in materiality. (shrink)

Much of my book Philosophy of Psychedelics is devoted to elaborating and defending two basic claims: that psychedelic therapy works mainly by changing mental representations of the self, and that it has many epistemic benefits consistent with a naturalistic worldview. The commentaries in this symposium generally focus on one or the other of these claims. On the mechanistic front, the commentaries by Hoffman and by Martin and Sterzer seek to supplement my account by drawing attention to factors it does not (...) emphasize. In this reply I agree with most of their claims, but propose some important qualifications. Meanwhile, the commentaries by Lyon and Farrenikova and by Colombo challenge some core commitments of my account. I agree with many of their claims, but defend some of these core commitments. On the epistemological front, Bortolotti and Murphy-Hollies endorse the overall shape of my account and make some productive connections to ideas concerning agency-first epistemology and self know-how. Caporuscio brings into play the idea of self-shaping, which connects to self know-how, but argues against certain core claims of my account. I endorse many of these claims about agency-first, self know-how, and self-shaping, but propose some important qualifications. Finally, Fink agrees that psychedelic experiences can have some epistemic benefits, but argues that these do not pertain to epistemic justification, and that the main benefit is increased understanding. I am sympathetic to Fink’s proposal about understanding, but criticize some of his arguments for the thesis of Psychedelic Justification Impossibilism. (shrink)

In this précis I summarise the main ideas of my book Philosophy of Psychedelics. The book discusses philosophical issues arising from the therapeutic use of “classic” psychedelic drugs such as psilocybin and LSD. The book is organised around what I call the Comforting Delusion Objection to psychedelic therapy: the concern that this novel and promising treatment relies essentially on the induction of non-naturalistic metaphysical beliefs, rendering it epistemically objectionable. I begin the précis by summarizing material from chapters two and three (...) of the book, which review evidence for the therapeutic efficacy of psychedelics, and the facts about their clinical use that prompt the Comforting Delusion Objection. I then summarize materials from chapters four and five of the book, which argue that psychedelic therapy works neither by experience-independent processes of neuroplasticity, nor by inducing non-naturalistic metaphysical ideations, but by altering mental representations of the self. Next, I summarise the specific, speculative account of how this might work that is developed in chapters six and seven of the book. This account is based on the predictive processing theory of brain function and the self-binding theory of self-representation. Chapters eight and nine of the book argue, on the basis of this account, that psychedelic therapy can have significant epistemic and spiritual benefits that are compatible with a naturalistic worldview. I summarize this material, and then, finally, the overall conclusions about psychedelic therapy drawn in the tenth and final chapter of the book. (shrink)

Any complete understanding of human psychology must take into account that a brain’s actions in the world are mediated by the body it belongs to. In the process of such interaction the human being creates artificial things, structures and mechanisms, such as technology, relationships, and culture. The subjective world is not simply the interactions between neurons at different systemic levels, but the existence of mental contents, which are determined by specific features of a certain domain of reality with which a (...) cognitive agent interacts by means of her actions. It is possible to understand specific features of the subjective world with the conception of the “embodied” and “inactive” cognition. In this framework, the problems of consciousness of consciousness, free will, the possibility of “reading” another mind and constructing mental phenomena are analyzed. If cognitive studies are not used for manipulating humans, and are not means of human degradation they must take into consideration specific features of the human phenomenon: the belonging of the human being to the social world and the world of culture. The development of cognitive studies can lead humans to new levels and contribute to new interpretations of humanism. However, under certain conditions, this development can lead to the death of the human being. This paper shows that some Soviet philosophers and psychologists, during the second half of the twentieth century, anticipated the formulations and solutions of several contemporary key problems in cognitive science before these problems emerged.

The goal of this paper is to encourage participants in the debate about the locus of cognition (e.g., extended mind vs embedded mind) to turn their attention to noteworthy anthropological and sociological considerations typically (but not uniquely) arising from transhumanist and posthumanist research. Such considerations, we claim, promise to potentially give us a way out of the stalemate in which such a debate has fallen. A secondary goal of this paper is to impress trans and post-humanistically inclined readers to embrace (...) (or at least seriously reflect on) the extended mind thesis as a potential gamechanger to the state of play in their own debates. We start off (Sect. 1) by reviewing two crucial ideas (homo faber and plasticity of the body schema) that are instrumental in setting up the dispute between extended and embedded. We then summarise (Sect. 2), the stalemate between these two competing accounts of cognition, and review some of the dialectics underlying it. In Sect. 3, to get out of the stalemate, we propose to focus on a series of important anthropological and sociological considerations derived from and related to trans and posthumanist research. In doing so, we claim (Sect. 4) that an extended approach to cognition becomes anthropologically preferable and morally as well as socially more desirable than an embedded one. (shrink)
