This paper argues that, assuming some widely held views about how vision justifies beliefs, there is an important epistemic asymmetry between visual perception and the perception of bodily sensations. This asymmetry arises when we consider the epistemic significance of the distinction between low-level and high-level properties in perceptual experience. I argue that a distinction exists between low-level and high-level properties of bodily sensations which parallels that distinction in the objects of visual experience. I then survey evidence revealing systematic unreliability in (...) an important dimension of our perception of low-level bodily sensational properties. I argue that this unreliability results in an epistemic asymmetry with vision. I conclude by sketching some implications of this asymmetry for developing a general, unified theory of perceptual justification. (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.

Various psychopathologies of self-awareness, such as somatoparaphrenia and thought insertion in schizophrenia, might seem to threaten the viability of the higher-order thought (HOT) theory of consciousness since it requires a HOT about one’s own mental state to accompany every conscious state. The HOT theory of consciousness says that what makes a mental state a conscious mental state is that there is a HOT to the effect that “I am in mental state M.” I have argued in previous work that a (...) HOT theorist can adequately respond to this concern with respect to somatoparaphrenia and thought insertion. There is also Cotard syndrome which is a rare neuropsychiatric disorder in which people hold the delusional belief that they are dead, do not exist, or have lost their blood or internal organs. In this paper, I argue that HOT theory has nothing to fear from it either and can consistently account for what happens in such unusual cases. I analyze Cotard syndrome in light of my previous discussion of somatoparaphrenia and thought insertion, and argue that HOT theory can provide a somewhat analogous account without the worry of inconsistency. It is crucial to recognize that there are multiple “self-concepts” and levels of HOTs which can help to provide a more nuanced explanation. With regard to the connection between consciousness and self-consciousness, it is proposed that Cotard patients are indeed capable of having some “I-thoughts” about their bodies and mental states.

Abstract: What grounds the experience of our body as our own? Can we rationally doubt that this is our own body when we feel sensations in it? This article shows how recent empirical evidence can shed light on issues on the body and the self, such as the grounds of the sense of body ownership and the immunity to error through misidentification of bodily self-ascriptions. In particular, it discusses how bodily illusions (e.g., the Rubber Hand Illusion), bodily disruptions (e.g., somatoparaphrenia), (...) and the multimodal nature of bodily self-knowledge challenge a classic view of ownership and immunity that puts bodily sensations at its core.

One way to characterize the special relation that one has to one's own body is to say that only one's body appears to one from the inside. Although widely accepted, the nature of this specific experiential mode of presentation of the body is rarely spelled out. Most definitions amount to little more than lists of the various body senses (including senses of posture, movement, heat, pressure, and balance). It is true that body senses provide a kind of informational access to (...) one's own body, which one has to no other bodies, by contrast to external senses like vision, which can take many bodies as their object. But a theory of bodily awareness needs to take into account recent empirical evidence that indicates that bodily awareness is infected by a plague of multisensory effects, regardless of any dichotomy between body senses and external senses. Here I will argue in favour of a multimodal conception of bodily awareness. I will show that the body senses fail to fully account for the content of bodily experiences. I will then propose that vision helps compensate for the insufficiencies of the body senses in people who can see. I will finally argue that the multimodality of bodily experiences does not prevent privileged access to one's body. (shrink)

O presente paper integra o projeto de pesquisa que estou desenvolvendo, e cuja finalidade é a de erigir um modelo teórico dedicado ao clássico e sempre reinventado ‘problema das relações mente-corpo’. O estágio atual desta pesquisa se dedica a conciliar uma perspectiva emergentista das propriedades mentais com a tese de que a mente emerge das indissociáveis relações de interação e de integração entre encéfalo, corpo-propriamente-dito e meio-ambiente. Para tanto, buscarei demarcar as razões para defender uma abordagem que seja monista e, (...) ao mesmo tempo, incompatível com as perspectivas fisicalistas que aderiram em maior ou menor grau ao programa reducionista. Como pretendo sustentar, a perspectiva emergentista é a que melhor se adequa a essas exigências. Em sentido diverso do fisicalismo reducionista, proponho a defesa de um fisicalismo centrado nas noções de complexidade e de irredutibilidade das propriedades emergentes. (shrink)

This study investigates eight case reports of spontaneously emerging, brief episodes of vivid altered states of Selfhood (ASoSs) that occurred during mental exercise in six long-term meditators by using a neurophenomenological electroencephalography (EEG) approach. In agreement with the neurophenomenological methodology, first-person reports were used to identify such spontaneous ASoSs and to guide the neural analysis, which involved the estimation of three operational modules of the brain self-referential network (measured by EEG operational synchrony). The result of such analysis demonstrated that the (...) documented ASoSs had unique neurophenomenological profiles, where several aspects or components of Selfhood (measured neurophysiologically and phenomenologically) are affected and expressed differently, but still in agreement with the neurophysiological three-dimensional construct model of the complex experiential Selfhood proposed in our earlier work (Fingelkurts et al. in Conscious Cogn, 2020).

-/- Human beings are conscious not only of the world around them but also of themselves: their activities, their bodies, and their mental lives. They are, that is, self-conscious (or, equivalently, self-aware). Self-consciousness can be understood as an awareness of oneself. But a self-conscious subject is not just aware of something that merely happens to be themselves, as one is if one sees an old photograph without realising that it is of oneself. Rather a self-conscious subject is aware of themselves (...) as themselves; it is manifest to them that they themselves are the object of awareness. Self-consciousness is a form of consciousness that is paradigmatically expressed in English by the words “I”, “me”, and “my”, terms that each of us uses to refer to ourselves as such. -/- A central topic throughout the history of philosophy—and increasingly so since the seventeenth century—the phenomena surrounding self-consciousness prompt a variety of fundamental philosophical and scientific questions, including its relation to consciousness; its semantic and epistemic features; its realisation in both conceptual and non-conceptual representation; and its connection to our conception of an objective world populated with others like ourselves.

It is widely assumed that ordinary conscious experience involves some form of sense of self or consciousness of oneself. Moreover, this claim is often restricted to a 'thin' or 'minimal' notion of self-consciousness, or even 'the simplest form of self-consciousness', as opposed to more sophisticated forms of self-consciousness which are not deemed ubiquitous in ordinary experience. These formulations suggest that self-consciousness comes in degrees, and that individual subjects may differ with respect to the degree of self-consciousness they exhibit at a (...) given time. In this article, I critically examine this assumption. I consider what the claim that self-consciousness comes in degrees may mean, raise some challenges against the different versions of the claim, and conclude that none of them is both coherent and particularly plausible.
