Definitions of consciousness need to be sufficiently broad to include all examples of conscious states and sufficiently narrow to exclude entities, events and processes that are not conscious. Unfortunately, deviations from these simple principles are common in modern consciousness studies, with consequent confusion and internal division in the field. The present paper gives example of ways in which definitions of consciousness can be either too broad or too narrow. It also discusses some of the main ways in which pre-existing theoretical (...) commitments (about the nature of consciousness, mind and world) have intruded into definitions. Similar problems can arise in the way a “conscious process” is defined, potentially obscuring the way that conscious phenomenology actually relates to its neural correlates and antecedent causes in the brain, body and external world. Once a definition of “consciousness” is firmly grounded in its phenomenology, investigations of its ontology and its relationships to entities, events and processes that are not conscious can begin, and this may in time transmute the meaning (or sense) of the term. As our scientific understanding of these relationships deepen, our understanding of what consciousness is will also deepen. A similar transmutation of meaning (with growth of knowledge) occurs with basic terms in physics such as "energy", and "time.". (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)

Recently, philosophers with an interest in consciousness have turned their attention towards “fringe states of consciousness”. Examples include dreams, trances, and meditative states. Teetering between wakefulness and non-consciousness, fringe states illuminate the limits and boundaries of consciousness. This paper aims to give a coherent conceptualisation of deep meditative states, focussing in particular on phenomenal temporality during meditation. Advanced meditators overwhelmingly describe deep states of meditation as atemporal and timeless; however, they also report being continuously alert while meditating. I intend to (...) give a coherent interpretation of this apparent contradiction. After introducing some candidate interpretations, I shall argue that during (deepest) meditation, the subject experiences ‘pure duration’ without temporal structure. This, I argue, explains best why meditators describe deep meditation as ongoing but timeless awareness. A central part of the paper will expand on an account of phenomenal duration without phenomenal succession. The conclusion points towards some further avenues of research. (shrink)

I am aware of the tree and its leaves, but am I aware of my awareness of these things? When I try to introspect my awareness, I just find myself attending to objects and their properties. This observation is known as the ‘transparency of experience’. On the other hand, I seem to directly know that I am aware. Given the first observation, it is not clear how I know that I am aware. Fred Dretske thought that the problem was so (...) acute that he issued the challenge of answering ‘How do you know that you are not a zombie?’ I propose that a view found in the Advaita Vedanta, that awareness is self luminous, reconciles these two observations. I understand self-luminosity as the thesis that: (1) I am implicitly aware of my awareness and (2) I am phenomenally aware of a distinct phenomenal character of my awareness. In support of the first claim, that I apparently only attend to objects in the world when introspecting perceptual experience, suggests that I do not know my awareness explicitly, but rather that I must know it implicitly. In support of the second claim, I argue that the mere fact that I am perceptually conscious is not sufficient to allow me to know that I am perceptually conscious. In particular, the qualities I am perceptually aware of do not tell me that I aware of them, rather they just seem to be properties of objects. I also assess whether strategies for responding to Cartesian sceptical scenarios can be employed against Dretske’s consciousness scepticism. I argue that these strategies either fail to distinguish me from a zombie or they do not adequately describe my epistemic situation. By contrast to other accounts, if awareness has its own distinct phenomenal character, then it cannot be considered to be a prima facie property of the world, hence the self-luminosity of awareness provides a plausible account of how I know that I’m not a zombie.

In contentless experience (sometimes termed _pure consciousness_) there is an absence of mental content such as thought, perception, and mental imagery. The path to contentless experience in meditation can be taken to comprise the meditation technique, and the experiences (“interim-states”) on the way to the contentless “goal-state/s”. Shamatha, Transcendental, and Stillness Meditation are each said to access contentless experience, but the path to that experience in each practice is not yet well understood from a scientific perspective. We have employed evidence (...) synthesis to select and review 135 expert texts from those traditions. In this paper we describe the techniques and interim-states based on the expert texts and compare them across the practices on key dimensions. Superficially, Shamatha and Transcendental Meditation appear very different to Stillness Meditation in that they require bringing awareness to a meditation object. The more detailed and systematic approach taken in this paper indicates that posturally Shamatha is closer to Stillness Meditation, and that on several other dimensions Shamatha is quite different to both other practices. In particular, Shamatha involves greater measures to cultivate attentional stability and vividness with respect to an object, greater focusing, less tolerance of mind-wandering, more monitoring, and more deliberate doing/control. Achieving contentless experience in Shamatha is much slower, more difficult, and less frequent. The findings have important implications for taxonomies of meditation and for consciousness, neuroscientific, and clinical research/practice, and will provide new and useful insights for meditation practitioners.

In this paper, I investigate the phenomenology of awakening in Chinese Zen Buddhism. In this tradition, to awaken is to ‘see your true nature’. In particular, the two aspects of awakening are: (1) seeing that the nature of one’s self or mind is empty or void and (2) an erasing of the usual (though merely apparent) boundary between subject and object. In the early Zen tradition, there are many references to awakening as chopping off your head, not having eyes, nose (...) and tongue, and seeing your ‘Original Face’. These references bear a remarkable resemblance to an approach to awakening developed by Douglas Harding. I will guide the reader through a series of Harding’s first-person experiments which investigate the gap where you cannot see your own head. I will endeavour to show that these methods, although radically different from traditional meditation techniques, result in an experience with striking similarities to Zen accounts of awakening, in particular, as experiencing oneself as empty or void and yet totally united with the given world. The repeatability and apparent reliability of these first-person methods opens up a class of awakening experience to empirical investigation and has the potential to provide new insights into nondual traditions.

Shamatha, Transcendental, and Stillness Meditation are said to aim for “contentless” experiences, where mental content such as thoughts, perceptions, and mental images is absent. Silence is understood to be a central feature of those experiences. The main source of information about the experiences is texts by experts from within the three traditions. Previous research has tended not to use an explicit scientific method for selecting and reviewing expert texts on meditation. We have identified evidence synthesis as a robust and transparent (...) method that is suitable for this purpose. In this paper we use evidence synthesis based on expert texts to examine silence/quietness as a feature of the contentless experiences in the three practices. Objective criteria were used to select a sample of 135 expert texts. A database containing the expert descriptions of the meditation techniques and experiences was produced by extracting the relevant material from the publications and coding that material to differentiate individual features. The database, which forms part of the Supplementary Material for this paper, identifies each feature of the contentless experiences referred to in the expert texts, including silence/quietness. Our key finding is that the experts indicate silence/quietness has a particular connection with stillness, and the absence of concepts, mental activity/noise, thoughts, and disturbance. Further analysis leads to the following insights. The silence/quietness reflects the absence of thoughts and sounds, and this fits neatly with a conception of silence/quietness as the absence of internal and external noise. In some cases the terms silence and quietness may also reflect the absence of other disturbances such as non-auditory perceptions, mental images, and negative feelings. That would fit with a conception of silence/quietness as complete calm or absence of disturbance. It is not clear from the expert texts how silence/quietness is distinct from other features such as stillness that also reflect the absence of disturbances. As a separate matter, silence/quietness has connections with all the other features of the contentless experiences, but the closeness of the connections varies. Our work uncovers fine distinctions and ambiguities which lead to new research questions that can be explored in future studies. (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)

This dissertation defends the reliability of first-person methods for studying consciousness, and applies first-person experiments to two philosophical problems: the experience of size and of the self. In chapter 1, I discuss the motivations for taking a first-person approach to consciousness, the background assumptions of the dissertation and some methodological preliminaries. In chapter 2, I address the claim that phenomenal judgements are far less reliable than perceptual judgements (Schwitzgebel, 2011). I argue that the main errors and limitations in making phenomenal (...) judgements are due to domain-general factors, which are shared in the formation of perceptual judgements. Phenomenal judgements may still be statistically less reliable than perceptual judgements, though I provide reasons for thinking that Schwitzgebel (2011) overstates the case for statistical unreliability. I also provide criteria for distinguishing between reliable and unreliable phenomenal judgements, hence defending phenomenal judgements against general introspective scepticism. Having identified the main errors in making phenomenal judgements, in chapter 3, I discuss how first-person experiments can be used to control for these errors. I provide examples, and discuss how they overcome attentional and conceptual errors, minimise biases, and exhibit high intersubjective reliability. In chapter 4, I investigate size experience. I use first-person experiments and empirical findings to argue that distant things looking smaller cannot be explained as an awareness of instantiated objective properties (visual angle or retinal image size). I also discuss how an awareness of uninstantiated objective properties cannot adequately account for the phenomenal character of size experience. This provides support for a subjectivist account of variance in size experience. In chapter 5, I investigate the sense of self. I distinguish between a weak sense of self (for-me-ness) and a strong sense of self in which there is a polarity between subject and object. I use first-person experiments from Douglas Harding to demonstrate an explicit strong sense of self, specifically when I point at where others see my face. I also argue that this sense of self is not explained by inference, thoughts, feelings, imagination nor the viewpoint. Rather, it is part of the structure of experience that I seem to be looking from here. Even if there is a sense of self, there may be no self. The question of chapter 6 is whether there can be a direct experience of the self. I argue that to function as a bearer of experience the subject must be single and lack sensory qualities in itself. I use Harding’s first-person experiments to investigate the visual gap where I cannot see my head. I argue that it conforms to the above criteria, and hence is a candidate for being the subject. This finding, in conjunction with the fact that I seem to be looking from the same location, provides prima facie evidence for the reality of the subject. I hold then that contrary to Hume and most philosophers since, that there can be a direct self-experience, if one knows which direction to attend. (shrink)

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)

Objectives Practitioners in contemplative traditions commonly report experiencing an awareness that is distinct from sensory objects, thoughts, and emotions (“awareness itself”). They also report experiences of a void or underlying silence that is closely associated with this awareness. Subjects who carry out the Headless Way exercises frequently report an experience of emptiness or void at the same time as other contents (void-like experiences). The goals of this study were to (1) assess the reliability of these methods in eliciting the recognition (...) of awareness and void-like experiences in participants who had no prior exposure to these techniques, (2) investigate the prevalence of these experiences in these tasks, and (3) to differentiate these experiences from closely related and potential precursor experiences. -/- Method Twenty adults participated in in-depth individual interviews in which they were guided through the Headless Way exercises. A thematic analysis was conducted on the interview transcripts. -/- Results Twelve of the participants reported a void-like experience, and five participants reported an experience of awareness itself. These experiences were respectively categorized as subsets of the more general categories of perceptual absences and the sense of not being person-like. Another novel finding was the real-time reports of awareness and void-like experiences during the exercises. -/- Conclusions Our findings provide preliminary evidence that the Headless Way exercises can effectively induce experiences of emptiness and awareness in participants without prior experience. The findings suggest that such experiences can be elicited outside of a traditional meditation context, including in non-meditators. Furthermore, the experience of not being person-like and of perceptual absences may be precursors and more general forms of recognizing awareness itself and the void-like nature of the mind.

Objective: Mindfulness disposition is associated with various psychological factors and prevent emotional distress in chronic diseases. In the present study, we analyzed the key role of mindfulness dispositions in protecting the individual against psychological distress consequent to COVID-19 social distancing and quarantining. Methods: An online survey was launched on March 13, 2020, with 6,412 responses by April 6, 2020. Socio-demographic information, exposure to the pandemic, and quarantining were assessed together with psychological distress and mindfulness disposition. Multivariate linear regression analysis was (...) performed to study the influence of predictive factors on psychological distress and quality of life in Italian responders during the early days of lockdown. Pearson correlations were calculated to study the relations between mindfulness and psychiatric symptoms. Results: Multivariate linear regression run on socio-demographics, COVID-19-related variables, and mindfulness disposition as moderators of overall psychological distress showed that mindfulness was the best predictor of psychological distress (β = -0.504; p =.000). High negative correlations were found between mindfulness disposition and overall Global Severity Index (r = -.637; p =.000), while moderate to high associations were found between mindfulness and all SCL-90 sub-scales. Discussion: Findings showed that high dispositional mindfulness enhances well-being and helps in dealing with stressful situations such as the COVID-19 pandemic. Mindfulness-based mental training could represent an effective intervention to stem the post-traumatic psychopathological beginnings and preventing the onset of chronic mental disorders. (shrink)

Owing to its benefits on various cognitive aspects, one’s emotions and wellbeing, meditation has drawn interest from several researchers and common public alike. We have different meditation practices associated with many cultures and traditions across the globe. Current literature suggests significant changes in the neural activity among the different practices of meditation, as each of these practices contributes to distinct physiological and psychological effects. Although this is the case, we want to find out if there is an underlying commonality among (...) all these different practices. So, we ask the following questions related to different practices of meditation, the traditional goal of meditation and its significance - What is the central purpose of meditation? Do traditions define the final goal of all the practices of meditation? Are the purpose and goal of these practices different or is there a common goal to be attained through all these distinct practices? Embracing the traditional perspective, through this paper, we want to emphasize, although these techniques and practices may appear different on the periphery, eventually, they seem to subject one to the same experience at the end; a natural meditative state (discussed in various spiritual traditions as the goal of meditation). In view of future studies on different meditation practices and also those exploring this subjective state, we offer some interesting ideas based on the traditional insights on meditation. In this context, we would also like to make a few comments on the way contemporary researchers view different practices of meditation. (shrink)

This research extends and confirms recent brainwave findings that distinguished an individual’s sense-of-self along an Object-referral/Self-referral Continuum of self-awareness. Subjects were interviewed and were given tests measuring inner/outer orientation, moral reasoning, anxiety, and personality. Scores on the psychological tests were factor analyzed. The first unrotated PCA component of the test scores yielded a “Consciousness Factor,” analogous to the intelligence “g” factor, which accounted for over half of the variance among groups. Analysis of unstructured interviews of these subjects revealed fundamentally different (...) descriptions of self-awareness. Individuals who described themselves in terms of concrete cognitive and behavioral processes exhibited lower Consciousness Factor scores, lower frontal EEG coherence, lower alpha and higher gamma power during tasks, and less efficient cortical preparatory responses . In contrast, individuals who described themselves in terms of an abstract, independent sense-of-self underlying thought, feeling and action exhibited higher Consciousness Factor scores, higher frontal coherence, higher alpha and lower gamma power during tasks, and more efficient cortical responses. These data suggest that definable states of brain activity and subjective experiences exist, in addition to waking, sleeping and dreaming, that may be operationally defined by psychological and physiological measures along a continuum of Object-referral/Self-referral Continuum of self-awareness.

Contentless experience involves an absence of mental content such as thought, perception, and mental imagery. In academic work it has been classically treated as including states like those aimed for in Shamatha, Transcendental, and Stillness Meditation. We have used evidence synthesis to select and review 135 expert texts from within the three traditions. In this paper we identify the features of contentless experience referred to in the expert texts and determine whether the experiences are the same or different across the (...) practices with respect to each feature. We identify 65 features reported or implied in one or more practices, with most being reported or implied in all three. While there are broad similarities in the experiences across the traditions, we find that there are differences with respect to four features and possibly many others. The main difference identified is that Shamatha involves substantially greater attentional stability and vividness. Another key finding is that numerous forms of content are present in the experiences, including wakefulness, naturalness, calm, bliss/joy, and freedom. The findings indicate that meditation experiences described as contentless in the academic literature can in fact involve considerable variation, and that in many and perhaps most cases these experiences are not truly contentless. This challenges classical understandings in academic research that in these so-called contentless experiences all content is absent, and that the experiences are therefore an identical state of _pure consciousness_ or consciousness itself. Our assessment is that it remains an open question whether the experiences aimed for in the three practices should be classed as pure consciousness. Implications of our analysis for neuroscientific and clinical studies and for basic understandings of the practices are discussed. (shrink)

Deep sleep has traditionally been deemed as a period that lack consciousness. However, recent evidence challenges this assumption and highlights the possibility of experiencing awareness during deep sleep. By drawing from Indian philosophical traditions, this thesis defends a positive view of consciousness during dreamless sleep – the period of sleep where we are aware but not dreaming. Moreover, this thesis also challenges classic views on the nature of conscious states where consciousness is reduced to representational content. For that purpose, this (...) thesis develops a taxonomy of dreamless sleep that, contrary to other research in the area, considers the existence of different sorts of awareness with different degrees of content. Thus, a full spectrum of mental states during conscious dreamless sleep are considered: from awareness of substantial content to awareness devoid of content altogether. The aim of the thesis is to show how such a taxonomy can encourage a shift from a two-dimensional view of consciousness to a multidimensional one — from a view that only considers brain activation and reportable content to one that assesses conscious states on different level of analysis. This shift will result in an adequate conceptualisation of dreamless sleep as a period where we could have conscious states with content, but also, conscious states without content. Moreover, this shift on a multidimensional approach will allow us to undertake a proper comparison compare between different sleep phenomena. In order to develop this taxonomy of dreamless sleep, I explore definitions on awareness during dreamless sleep found in Indian philosophical traditions and Western analytical philosophy. From the definitions found in the literature, I argue that all the types of conscious states proposed in my taxonomy can be identified. Then, I test my taxonomy in a pilot study about awareness during deep sleep that I carried out. The results show that the different types of awareness can be recognised in the phenomenological descriptions gathered from the participants. Finally, I compare the phenomenon of dreamless sleep with other associated experiences, such as dreams and hypnagogia. My claim is that the differences among sleep phenomena are gradual and that in some cases there is not a strict cut-off line between them. Notwithstanding this assumption, I defend the development of future research were my proposed taxonomy can be improved by considering typical cases of dreamless sleep. (shrink)

The aim of this article is to take up three closely connected questions. First, does consciousness essentially involve subjectivity? Second, what is the connection, if any, between pre-reflective self-consciousness and subjectivity? And, third, does consciousness necessarily involve an ego or self? I will draw on the Yogācāra–Madhyamaka synthesis of Śāntarakṣita to develop an account of the relation between consciousness, subjectivity, and the self. I will argue, first, that phenomenal consciousness is reflexive or self-illuminating. Second, I will argue that consciousness necessarily (...) involves minimal subjectivity. Third, I will argue that neither the reflexivity nor the subjectivity of consciousness implies that there is any entity such as the self or ego over and above reflexive consciousness. Fourth, I will argue that what we normally think of as ‘the self’ is best understood as a complex, multi-layered process that emerges within the pre.. (shrink)

This paper seeks to analyse an under-discussed kind of self-control, namely the control of thoughts and sensations. I distinguish first-order control from second-order control and argue that their central forms are intentional concentration and intentional mindfulness respectively. These correspond to two forms of meditation, concentration meditation and mindfulness meditation, which have been regarded as central both in the traditions in which the practices arose and in the scientific literature on meditation. I analyse them in terms of their characteristic intentions, distinguish (...) them from concentration and mindfulness in general, and examine the relations between them. Concentration involves keeping the mind focused on a single object, while mindfulness requires noticing whatever mental states occupy the focus of one’s consciousness. In the course of the investigation I examine the role of phenomenology and volition in the activity of meditating, and how they change as meditative capacities develop. (shrink)

Neuroscientific scanning of meditators is taken as providing data on mystical experiences. However, problems concerning how the brain and consciousness are related cast doubts on whether any understanding of the content of meditative experiences is gained through the study of the brain. Whether neuroscience can study the subjective aspects of meditative experiences in general is also discussed. So too, whether current neuroscience can establish that there are “pure consciousness events” in mysticism is open to question. The discussion points to limitations (...) on neuroscience's capability to add to our understanding of the phenomenological content of mystical experiences. (shrink)

Implicit association of racial stereotypes is brought about by social conditioning. This conditioning can be explained by attractor networks. Reducing implicit bias through meditation can show the effectiveness of reducing the rigidity of attractor networks, thereby reducing subjectivity. Mindfulness meditation has shown to reduce bias from the use of one single guided session conducted before performing an Implicit Association Test. Attachment to socially conditioned racial bias should become less prevalent through practicing meditation over time. An experimental model is proposed to (...) test this claim along with a reconceptualization of consciousness based in meditative practice. (shrink)
