The Matrix presents a version of an old philosophical fable: the brain in a vat. A disembodied brain is floating in a vat, inside a scientist’s laboratory. The scientist has arranged that the brain will be stimulated with the same sort of inputs that a normal embodied brain receives. To do this, the brain is connected to a giant computer simulation of a world. The simulation determines which inputs the brain receives. When the brain produces outputs, these are fed back (...) into the simulation. The internal state of the brain is just like that of a normal brain, despite the fact that it lacks a body. From the brain’s point of view, things seem very much as they seem to you and me. (shrink)

Do you dream in color? If you answer Yes, how can you be sure? Before you recount your vivid memory of a dream featuring all the colors of the rainbow, consider that in the 1950s researchers found that most people reported dreaming in black and white. In the 1960s, when most movies were in color and more people had color television sets, the vast majority of reported dreams contained color. The most likely explanation for this, according to the philosopher Eric (...) Schwitzgebel, is not that exposure to black-and-white media made people misremember their dreams. It is that we simply don't know whether or not we dream in color. In Perplexities of Consciousness, Schwitzgebel examines various aspects of inner life and argues that we know very little about our stream of conscious experience. Drawing broadly from historical and recent philosophy and psychology to examine such topics as visual perspective, and the unreliability of introspection, Schwitzgebel finds us singularly inept in our judgments about conscious experience.

A renowned philosopher of the mind, also known for his groundbreaking work on Buddhism and cognitive science, Evan Thompson combines the latest neuroscience research on sleep, dreaming, and meditation with Indian and Western philosophy of the mind, casting new light on the self and its relation to the brain. Thompson shows how the self is a changing process, not a static thing. When we are awake we identify with our body, but if we let our mind wander or daydream, we (...) project a mentally imagined self into the remembered past or anticipated future. As we fall asleep, the impression of being a bounded self distinct from the world dissolves, but the self reappears in the dream state. If we have a lucid dream, we no longer identify only with the self within the dream. Our sense of self now includes our dreaming self, the "I" as dreamer. Finally, as we meditate--either in the waking state or in a lucid dream--we can observe whatever images or thoughts arise and how we tend to identify with them as "me." We can also experience sheer awareness itself, distinct from the changing contents that make up our image of the self. Contemplative traditions say that we can learn to let go of the self, so that when we die we can witness its dissolution with equanimity. Thompson weaves together neuroscience, philosophy, and personal narrative to depict these transformations, adding uncommon depth to life's profound questions. Contemplative experience comes to illuminate scientific findings, and scientific evidence enriches the vast knowledge acquired by contemplatives. (shrink)

This is a book for scholars of Western philosophy who wish to engage with Buddhist philosophy, or who simply want to extend their philosophical horizons. It is also a book for scholars of Buddhist studies who want to see how Buddhist theory articulates with contemporary philosophy. Engaging Buddhism: Why it Matters to Philosophy articulates the basic metaphysical framework common to Buddhist traditions. It then explores questions in metaphysics, the philosophy of mind, phenomenology, epistemology, the philosophy of language and ethics as (...) they are raised and addressed in a variety of Asian Buddhist traditions. In each case the focus is on philosophical problems; in each case the connections between Buddhist and contemporary Western debates are addressed, as are the distinctive contributions that the Buddhist tradition can make to Western discussions. Engaging Buddhism is not an introduction to Buddhist philosophy, but an engagement with it, and an argument for the importance of that engagement. It does not pretend to comprehensiveness, but it does address a wide range of Buddhist traditions, emphasizing the heterogeneity and the richness of those traditions. The book concludes with methodological reflections on how to prosecute dialogue between Buddhist and Western traditions. (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)

I am aware of the red and orange autumn leaves. Am I aware of my awareness of the leaves? Not so according to many philosophers. By contrast, many meditative traditions report an experience of awareness itself. I argue that such a pure awareness experience must have a non-sensory phenomenal character. I use Douglas Harding’s first-person experiments for assisting in recognising pure awareness. In particular, I investigate the gap where one cannot see one’s head. This is not a mere gap because (...) I seem to be looking from here. Critically, I claim, the experience of looking from here has a non-sensory phenomenal character. I argue that this sense of being aware cannot be reduced to egocentric visual-spatial relations nor the viewpoint because it continues when I close my eyes. Neither is a multisensory origin sufficient to explain why I seem to be at this central point rather than elsewhere. Traditionally, claims of a pure awareness experience have been restricted to highly trained individuals in very restricted circumstances. The innovation of Harding’s approach is that it reliably isolates a candidate for pure awareness using methods which can be replicated at any time. (shrink)

_A provocative essay challenging the idea of Buddhist exceptionalism, from one of the world’s most widely respected philosophers and writers on Buddhism and science_ Buddhism has become a uniquely favored religion in our modern age. A burgeoning number of books extol the scientifically proven benefits of meditation and mindfulness for everything ranging from business to romance. There are conferences, courses, and celebrities promoting the notion that Buddhism is spirituality for the rational, compatible with cutting‑edge science, indeed, “a science of the (...) mind.” In this provocative book, Evan Thompson argues that this representation of Buddhism is false. In lucid and entertaining prose, Thompson dives deep into both Western and Buddhist philosophy to explain how the goals of science and religion are fundamentally different. Efforts to seek their unification are wrongheaded and promote mistaken ideas of both. He suggests cosmopolitanism instead, a worldview with deep roots in both Eastern and Western traditions. Smart, sympathetic, and intellectually ambitious, this book is a must‑read for anyone interested in Buddhism’s place in our world today. (shrink)

Users of psychedelic drugs often report that their sense of being a self or ‘I’ distinct from the rest of the world has diminished or altogether dissolved. Neuroscientific study of such ‘ego dissolution’ experiences offers a window onto the nature of self-awareness. We argue that ego dissolution is best explained by an account that explains self-awareness as resulting from the integrated functioning of hierarchical predictive models which posit the existence of a stable and unchanging entity to which representations are bound. (...) Combining recent work on the ‘integrative self' and the phenomenon of self-binding with predictive processing principles yields an explanation of ego dissolution according to which self-representation is a useful Cartesian fiction: an ultimately false representation of a simple and enduring substance to which attributes are bound which serves to integrate and unify cognitive processing across levels and domains. The self-model is not a mere narrative posit, as some have suggested; it has a more robust and ubiquitous cognitive function than that. But this does not mean, as others have claimed, that the self-model has the right attributes to qualify as a self. It performs some of the right kinds of functions, but it is not the right kind of entity. Ego dissolution experiences reveal that the self-model plays an important binding function in cognitive processing, but the self does not exist. (shrink)

The Indian philosopher Acarya Nagarjuna (c. 150-250 CE) was the founder of the Madhyamaka (Middle Path) school of Mahayana Buddhism and arguably the most influential Buddhist thinker after Buddha himself. Indeed, in the Tibetan and East Asian traditions, Nagarjuna is often referred to as the "second Buddha." This book presents a survey of the whole of Nagarjuna's philosophy based on his key philosophical writings. His primary contribution to Buddhist thought lies in the further development of the concept of sunyata or (...) "emptiness." For Nagarjuna, all phenomena are without any svabhava, literally "own-nature" or "self-nature," and thus without any underlying substance. Particular emphasis is put on discussing Nagarjuna's thinking as philosophy. The present discussion shows how his thoughts on metaphysics, epistemology, the self, language, and truth present a unified theory of reality with considerable systematic appeal. The book offers a systematic account of Nagarjuna's philosophical position. It reads Nagarjuna in his own philosophical context, but also shows that the issues of Indian and Tibetan Buddhist philosophy have at least family resemblances to issues in European philosophy.

In this chapter, the author says that the standard view of brain‐in‐a‐vat scenario is endorsed by the people who created The Matrix. The author argues that the hypothesis that he is envatted is not a skeptical hypothesis, but a metaphysical hypothesis. That is, it is a hypothesis about the underlying nature of reality. According to the author, the Matrix Hypothesis is equivalent to a version of the following three‐part Metaphysical Hypothesis. First, physical processes are fundamentally computational. Second, our cognitive systems (...) are separate from physical processes, but interact with these processes. Third, physical reality was created by beings outside physical space‐time. The Metaphysical Hypothesis combines the Creation Hypothesis, the Computational Hypothesis, and the Mind‐Body Hypothesis. It also adds a more specific claim: the computational processes underlying physical space‐time were designed by the creators as a computer simulation of a world. (shrink)

Phenomenology: The Basics is a concise and engaging introduction to one of the important philosophical movements of the twentieth century and to a subject that continues to grow and diversify. Yet it is also a challenging subject, the elements of which can be hard to grasp. This lucid book provides an introduction to the core ideas of phenomenology and to the arguments of its principal thinkers, including Husserl, Heidegger and Merleau-Ponty. Written by a leading expert in the field, Dan Zahavi (...) examines and explains key questions such as: What is a phenomenological analysis? What are the methodological foundations of phenomenology? What does phenomenology have to say about intentionality, embodiment, intersubjectivity and the lifeworld? How do ideas from classic phenomenology relate to ongoing debates in the cognitive sciences and qualitative research? This second edition has been thoroughly revised and expanded. It contains a new chapter on critical phenomenology and updated discussions of the application of phenomenology in psychiatry, psychology, and qualitative research. Including a glossary of key terms and suggestions for further reading, Phenomenology: The Basics is a superb starting point for anyone seeking a concise and accessible introduction to this rich and fascinating subject.

A week ago, I heard James Conant give a talk at Tufts, entitled “Two Varieties of Skepticism” in which he distinguished two oft-confounded questions.

While first-person methods are essential for a science of consciousness, it is controversial what form these methods should take and whether any such methods are reliable. I propose that first-person experiments are a reliable method for investigating conscious experience. I outline the history of these methods and describe their characteristics. In particular, a first-person experiment is an intervention on a subject's experience in which independent variables are manipulated, extraneous variables are held fixed, and in which the subject makes a phenomenal (...) judgement about the target experience of the investigation. I examine historical and contemporary examples of first-person experiments: Mariotte’s demonstration of the visual blind spot, Kanizsa’s subjective contours, the Tse Illusion, and investigations of the non-uniform resolution of the visual field. I discuss the role that phenomenal contrast plays in these methods, and how they overcome typical introspective errors. I argue that their intersubjective repeatability is an important factor in their scientific status, however, it is not the only factor. That they control for extraneous factors and confounds is another factor which sets them apart from pseudoscience (e.g., the perception of auras), and hence another reason for classifying them as genuine experiments. Furthermore, by systematically mapping out the structure of visual experience, these methods make scientific progress. Praises of such first-person experimental approaches may not always be sung by philosophers and psychologists, but they continue to flourish as respectable scientific methods nevertheless. (shrink)

G.E. Moore alludes to a notion of consciousness that is diaphanous, elusive to attention, yet detectable. Such a notion, I suggest, approximates what Bina Gupta has called `witness-consciousness'--in particular, the aspect of mode-neutral awareness with intrinsic phenomenal character. This paper offers a detailed definition and defence of the appearance and reality of witness-consciousness. While I claim that witness- consciousness captures the essence of subjectivity, and so must be accounted for in the `hard problem' of consciousness, it is not to be (...) confused with the more commonly defended notion of `for-me-ness'.

Introspective and phenomenological methods are once again being used to support the use of subjective reports, rather than objective behavioural measures, to investigate and measure consciousness. Objective measures are often seen as useful ways of investigating the range of capacities subjects have in responding to phenomena, but are fraught with the interpretive problems of how to link behavioural capacities with consciousness. Instead, gathering subjective reports is seen as a more direct way of assessing the contents of consciousness. This article explores (...) three different ways of gathering subjective reports that have been discussed in recent literature on consciousness, including immediate retrospection (Schwitzgebel [2007]) and two types of introspective training (Overgaard et al. [2004]; Schwitzgebel [2008]). Although not an exhaustive survey of the range of introspective methods now used, the discussion below highlights a range of general methodological problems with introspective methods, many identified up to a century ago. It is argued that none of the methodological problems established in earlier criticisms of the use of subjective reports have been dealt with, yet are still valid criticisms. Given that this is not the first time proponents of introspective, subjective measures of conscious have failed to answer these criticisms, this raises the question of whether the goal of providing a measure of consciousness is a methodological muddle worth pursuing.

Hume famously denied that he could experience the self. Most subsequent philosophers have concurred with this finding. I argue that if the subject is to function as a bearer of experience it must (1) lack sensory qualities in itself to be compatible with bearing sensory qualities and (2) be single so that it can unify experience. I use Douglas Harding’s first-person experiments to investigate the visual gap where one cannot see one’s own head. I argue that this open space conforms (...) to the above criteria and hence is consistent with being the subject. I respond to the objection that this location is merely a lack of visual experience. I argue that this space also encompasses sound and touch properties and hence functions as a bearer for other sensory modalities. These first-person findings provide prima facie support for the view that the subject is a thin bearer of experience. (shrink)

How to model non-egoic experiences – mental events with phenomenal aspects that lack a felt self – has become an interesting research question. The main source of evidence for the existence of such non-egoic experiences are self-ascriptions of non-egoic experiences. In these, a person says about herself that she underwent an episode where she was conscious but lacked a feeling of self. Some interpret these as accurate reports, but this is questionable. Thomas Metzinger, Rocco Gennaro, and Charles Foster have hinted (...) at the self-defeating nature of such statements if we take them to be genuine reports: Apparently, the reporter explicitly denies her existence during the selfless experience, but implicitly affirms her existence as a witness to that selfless experience in order to give a first-person report about it. So the content of such a report conflicts with the pragmatics of reporting. If all self-ascriptions of non-egoic experiences are self-defeating in this way, then they cannot count as evidence for the existence of non-egoic experiences. Here, I map out why such strong conclusions do not directly follow: What look like self-ascriptions of non-egoic experiences may occur for a number of reasons. Only some explanations for such utterances rely on a change in consciousness. Of those that do rely on a change in consciousness, only one is incoherent. But its alternatives do not lead to contradictions. I argue that the most likely change in phenomenality that leads to self-ascriptions of non-egoic experiences is not one where a felt self disappears, but where it expands. (shrink)

Many spiritual traditions employ certain mental techniques (meditation) which consist in inhibiting mental activity whilst nonetheless remaining fully conscious, which is supposed to lead to a realisation of one’s own true nature prior to habitual self-substantialisation. In this paper I propose that this practice can be understood as a special means of becoming aware of consciousness itself as such. To explain this claim I conduct some phenomenologically oriented considerations about the nature of consciousness qua presence and the problem of self-presence (...) of this presence. (shrink)

This book is the first to engage Zen Buddhism philosophically on crucial issues from a perspective that is informed by the traditions of western philosophy and religion. It focuses on one renowned Zen master, Huang Po, whose recorded sayings exemplify the spirit of the 'golden age' of Zen in medieval China, and on the transmission of these writings to the West. The author makes a bold attempt to articulate a post-romantic understanding of Zen applicable to contemporary world culture. While deeply (...) sympathetic to the Zen tradition, he raises serious questions about the kinds of claims that can be made on its behalf. (shrink)

This paper will explore the integration of elements of traditional Eastern meditative procedures with modern objective scientific methodologies. In contrast to the introspective methods usually relied on in modern Western treatments of consciousness, the Eastern procedures in question have the possible advantage of being the products of centuries of effort to develop systematic first-person exploratory methodologies. But since these methodologies developed outside of the context of our traditions of science, their reported results of course cannot simply be taken at face (...) value. Nevertheless, aspects of their internal logic and putative results appear to be cross-culturally congruent, despite great differences of metaphysical frameworks and social milieux. Thus examining them and their effects in the context of modern scientific methodologies and criteria may well prove useful to us in our own task of developing a significant science of consciousness. In the paper we will accordingly describe some common methodological features and claimed results found in several major Eastern meditative traditions, discuss conceptual and methodological problems they raise, review some relevant scientific research on contemporary meditating subjects, and suggest some implications for the scientific study of consciousness. In particular, it will be suggested that the existing meditation-related research already indicates that Eastern varieties of meditative procedures should prove to be a useful component of any future science of consciousness.

Suppose we were to randomly pick out a book on Buddhism or Eastern Philosophy and turn to the section on 'no-self' (anatt?). On this central teaching, we would most likely learn that the Buddha rejected the Upanisadic notion of Self (?tman), maintaining that a person is no more than a bundle of impermanent, conditioned psycho-physical aggregates (khandhas). The rejection of ?tman is seen by many to separate the metaphysically 'extravagant' claims of Hinduism from the austere tenets of Buddhism. The status (...) quo has not, however, gone unchallenged. I shall join forces against this pernicious view, integrating some recent contributions into a sustained, two-pronged argument against no-?tman theories of anatt?. At the end it shall be suggested, in line with Thanissaro Bhikkhu, that anatt? is best understood as a practical strategy rather than as a metaphysical doctrine. (shrink)

Eric Schwitzgebel (2011) argues that phenomenal judgments are in general less reliable than perceptual judgments. This paper distinguishes two versions of this unreliability thesis. The process unreliability thesis says that unreliability in phenomenal judgments is due to faulty domain-specific mechanisms involved in producing these judgments, whereas the statistical unreliability thesis says that it is simply a matter of higher numbers of errors. Against the process unreliability thesis, I argue that the main errors and limitations in making phenomenal judgments can be (...) accounted for by domain-general factors: attention, working memory limits and conceptualization. As these factors are shared with the production of perceptual judgments, errors in phenomenal judgments are not due to faulty domain-specific processes. Furthermore, this account defends phenomenal judgments against general scepticism by providing criteria for distinguishing between reliable and unreliable phenomenal judgments. (shrink)

Zen Buddhism as it has been discovered by the West in our time emerges as one of the great challenges to Western philosophy, psychology, and religion. The present volume, composed of the work of D. T. Suzuki, Zen's chief exponent in English, and presented to Western readers by William Barrett, is intended to introduce the general reader to the history and spirit of Zen.

This paper presents the pure consciousness theory of self, derived from Eastern meditation traditions, and uses it to unravel some of the paradoxes of Western philosophical models of the self. The theory is ontologically neutral and compatible with the widest variety of different ontologies. However the theory does, I think, have significant implications for questions of personal identity, emotional maturity and moral values, but exploring these topics here would take us too far afield. The article attempts to show something of (...) the potential value for our traditional philosophical discussions of self of taking into account the pure consciousness experience, widely discussed in Eastern, but not Western, philosophical traditions. For if the phenomenological analyses are even roughly correct, it would appear that the experience is capable of resolving some major Western issues about self, clarifies our commonsense intuition, and is properly identified by philosophical analysis as being experience of self itself.
