What is it like to dream? On an orthodox view, dreams involve misleading sensations and false beliefs. I argue, on philosophical, psychological, and neurophysiological grounds, that orthodoxy about dreaming should be rejected in favor of an imagination model of dreaming. I am thus in partial agreement with Colin McGinn, who has argued that we do not have misleading sensory experiences while dreaming, and partially in agreement with Ernest Sosa, who has argued that we do not form false beliefs while dreaming. (...) Rather, on my view, dreams involve mental imagery and propositional imagination. I defend the imagination model of dreaming from objections. (shrink)

Ernest Sosa has argued that the solution to dream scepticism lies in an understanding of dreams as imaginative experiences – when we dream, on this suggestion, we do not believe the contents of our dreams, but rather imagine them. Sosa rebuts scepticism thus: dreams don’t cause false beliefs, so my beliefs cannot be false, having been caused by dreams. I argue that, even assuming that Sosa is correct about the nature of dreaming, belief in wakefulness on these grounds is epistemically (...) irresponsible. The proper upshot of the imagination model, I suggest, is to recharacterize the way we think about dream scepticism: the sceptical threat is not, after all, that we have false beliefs. So even though dreams don’t involve false beliefs, they still pose a sceptical threat, which I elaborate. (shrink)

The word ?consciousness? is notoriously ambiguous. This is mainly because it is not a term of art, but a mundane word we all use quite frequently, for different purposes and in different everyday contexts. In this paper, I discuss consciousness in one specific sense of the word. To avoid the ambiguities, I introduce a term of art ? intransitive self-consciousness ? and suggest that this form of self-consciousness is an essential component of the folk notion of consciousness. I then argue (...) for a specific account of consciousness as intransitive self-consciousness. According to this account, a mental state is conscious iff it represents its own occurrence. The argument is a ?modernizing? modification of an older argument due to Aristotle and Brentano. (shrink)

Recent years have seen a heightened focus on the study of minimal forms of awareness during sleep to advance the study of consciousness and understand what makes a state conscious. This focus draws on an increased interest in anecdotical descriptions made by classic Indian philosophical traditions about unusual forms of awareness during sleep. For instance, in the so-called state of witnessing-sleep or luminosity sleep, one is said to reach a state that goes beyond ordinary dreaming and abide in a state (...) of just awareness, a state in which one is not aware of anything else other than one’s own awareness. Moreover, for these traditions, this state is taken to be the essence or background of consciousness. Reports on such a state opens the door to exciting new lines of research in the study of consciousness, such as inquiry into the so-called “objectless” awareness during sleep—states of awareness that lack an ordinary object of awareness. In this two-staged research project, we attempted to find the phenomenological blueprints of such forms of awareness during sleep in 18 participants by conducting phenomenological interviews, informed by a novel tool in qualitative research, the micro-phenomenological interview (MPI) method. Following a phenomenological analysis, we isolated a similar phase across 12 reported experiences labelled as ‘nothingness phase’ since it described what participants took to be an experience of ‘nothingness’. his common phase was characterised by minimal sense of self—a bodiless self, yet experienced as being ‘somewhere’—, the presence of non-modal sensations, relatively pleasant emotions, an absence of visual experience, wide and unfocused attention, and an awareness of the state as it unfolded.

This paper presents a pilot study that explores instances of objectless awareness during sleep: conscious experiences had during sleep that prima facie lack an object of awareness. This state of objectless awareness during sleep has been widely described by Indian contemplative traditions and has been characterised as a state of consciousness-as-such; while in it, there is nothing to be aware of, one is _merely_ conscious (cf. Evans-Wentz, 1960 ; Fremantle, 2001 ; Ponlop, 2006 ). While this phenomenon has received different (...) names in the literature, such as ‘witnessing-sleep’ and ‘clear light sleep’ among others, the specific phenomenological profile of this state has not yet been rigorously studied. This paper aims at presenting a preliminary investigation of objectless consciousness during sleep using a novel tool in qualitative research that can guide future research. Five participants experiencing objectless consciousness during sleep were interviewed following the _Micro-phenomenological Interview_ technique (MPI; Petitmengin, 2005, 2006 ). All participants reported an experience they had during sleep in which there was no scenery and no dream. This period labelled as ‘No Scenery/Void’ was either preceded by the dissolution of a lucid dream or by other forms of conscious mentation. The analysis of the results advances four experiential dimensions during this state of void, namely (1) Perception of absence, (2) Self-perception, (3) Perception of emotions, and (4) Perception of awareness. While the results are primarily explorative, they refer to themes found in the literature to describe objectless sleep and point at potential avenues of research. The results from this study are taken as indications to guide future operationalisations of this phenomenon. (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 this paper, we present new cases of illusion and hallucination that have not heretofore been identified. We argue that such cases show that the traditional accounts of illusion and hallucination are incorrect because they do not identify all of the cases of non-veridical experience that they need to and they elide important differences between cases. In light of this, we present new and exhaustive definitions of illusion and hallucination. First, we explicate the traditional accounts of illusion and hallucination. We (...) then proceed to outline cases of pure property experience—that is, experience as of properties, but not as of objects. We suggest that some might find it to be plausible that olfactory experience is of this kind. We argue that, within instances of such pure property experience, one can identify cases of veridical property perception, illusory property perception and hallucinatory property experience. With these distinctions in hand, we re-examine ordinary cases of experiences as of objects having properties. Drawing on the ideas uncovered by considering pure property experience, we bring to light many new cases of illusion and hallucination within ordinary experience as of objects having properties. These consist in different combinations of veridical perception, illusory perception and hallucination of both objects and properties. In order to accept that these new cases of illusion and hallucination exist in ordinary experience as of objects having properties, nothing turns on accepting the idea that there is pure property experience, or that olfactory experience is an instance of it. Such a conception of experience is simply a tool—a ladder to gain a good vantage point from which one can appreciate that there are these further cases. But this is a ladder that, as Wittgenstein might say, can be thrown away once it is used. Identifying new instances of illusion and hallucination provides much needed, important data for testing theories of experience and perception—theories that are frequently motivated, and should be judged, by their ability to account for cases of illusion and hallucination.

This paper explores some of the areas where neuroscientific and philosophical issues intersect in the study of self-consciousness. Taking as point of departure a paradox (the paradox of self-consciousness) that appears to block philosophical elucidation of self-consciousness, the paper illustrates how the highly conceptual forms of self-consciousness emerge from a rich foundation of nonconceptual forms of self-awareness. Attention is paid in particular to the primitive forms of nonconceptual self-consciousness manifested in visual perception, somatic proprioception, spatial reasoning and interpersonal psychological interactions. (...) The study of these primitive forms of self-consciousness is an interdisciplinary enterprise and the paper considers a range of points of contact where philosophical work can illuminate work in the cognitive sciences, and vice versa.

In this article, we present results from an interdisciplinary research project aimed at assessing consciousness in dreams. For this purpose, we compared lucid dreams with normal non-lucid dreams from REM sleep. Both lucid and non-lucid dreams are an important contrast condition for theories of waking consciousness, giving valuable insights into the structure of conscious experience and its neural correlates during sleep. However, the precise differences between lucid and non-lucid dreams remain poorly understood. The construction of the Lucidity and Consciousness in (...) Dreams scale was based on theoretical considerations and empirical observations. Exploratory factor analysis of the data from the first survey identified eight factors that were validated in a second survey using confirmatory factor analysis: INSIGHT, CONTROL, THOUGHT, REALISM, MEMORY, DISSOCIATION, NEGATIVE EMOTION, and POSITIVE EMOTION. While all factors are involved in dream consciousness, realism and negative emotion do not differentiate between lucid and non-lucid dreams, suggesting that lucid insight is separable from both bizarreness in dreams and a change in the subjectively experienced realism of the dream.

Thirty-eight “practiced” dreamers and 50 “novice” dreamers completed questionnaires assessing the cognitive, metacognitive, and emotional qualities of recent waking and dreaming experiences. The present findings suggest that dreaming cognition is more similar to waking cognition than previously assumed and that the differences between dreaming and waking cognition are more quantitative than qualitative. Results from the two studies were generally consistent, indicating that high-order cognition during dreaming is not restricted to individuals practiced in dream recall or self-observation. None of the measured (...) features was absent or infrequent in reports of either dreaming or waking experiences. Recollections of dreaming and waking experiences were similar for some cognitive features and different for other features. (shrink)

The concept of “self-awareness” ( svasaṃvedana ) enters Buddhist epistemological discourse in the Pramāṇasamuccaya and - vṛtti by Dignāga (ca. 480–540), the founder of the Buddhist logico-epistemological tradition. Though some of the key passages have already been dealt with in various publications, no attempt has been made to comprehensively examine all of them as a whole. A close reading is here proposed to make up for this deficit. In connection with a particularly difficult passage (PS(V) 1.8cd-10) that presents the means (...) of valid cognition and its result ( pramāṇa/pramāṇaphala ), a new interpretation is suggested, inspired by the commentary of Jinendrabuddhi. This interpretation highlights an aspect of selfawareness that has hitherto not been claimed for Dignāga: self-awareness offers essentially subjective access to one’s own mental states and factors.

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)

Two aspects of consciousness are first considered: consciousness as awareness (phenomenological meaning) and consciousness as strategic control (functional meaning). As to awareness, three types can be distinguished: first, awareness as the phenomenal experiences of objects and events; second, awareness as meta-awareness, i.e., the awareness of mental life itself; third, awareness as self-awareness, i.e., the awareness of being oneself. While phenomenal experience and self-awareness are usually present during dreaming (even if many modifications are possible), meta-awareness is usually absent (apart from some (...) particular experiences of self-reflectiveness) with the major exception of lucid dreaming. Consciousness as strategic control may also be present in dreams. The functioning of consciousness is then analyzed, following a cognitive model of dream production. In such a model, the dream is supposed to be the product of the interaction of three components: (a) the bottom-up activation of mnemonic elements coming from LTM systems, (b) interpretative and elaborative top-down processes, and (c) monitoring of phenomenal experience. A feedback circulation is activated among the components, where the top-down interpretative organization and the conscious monitoring of the oneiric scene elicitates other mnemonic contents, according to the requirements of the dream plot. This dream productive activity is submitted to unconscious and conscious processes. (shrink)

The study of the feeling of knowing may have implications for some of the metatheoretical issues concerning consciousness and control. Assuming a distinction between information-based and experience-based metacognitive judgments, it is argued that the sheer phenomenological experience of knowing (''noetic feeling'') occupies a unique role in mediating between implicit-automatic processes, on the one hand, and explicit-controlled processes, on the other. Rather than reflecting direct access to memory traces, noetic feelings are based on inferential heuristics that operate implicitly and unintentionally. Once (...) such heuristics give rise to a conscious feeling that feeling can then affect controlled action. Examination of the cues that affect noetic feelings suggest that not only do these feelings inform controlled action, but they are also informed by feedback from the outcome of that action. (shrink)

It is now 25 years since Gareth Evans introduced the distinction between conceptual and nonconceptual content in The Varieties of Reference. This is a fitting time to take stock of what has become a complex and extended debate both within philosophy and at the interface between philosophy and psychology. Unfortunately, the debate has become increasingly murky as it has become increasingly ramified. Much of the contemporary discussion does not do full justice to the powerful theoretical tool originally proposed by Evans (...) and subsequently refined by theorists in the late 1980’s and early 1990’s – most effectively, I think, by Christopher Peacocke (particularly in his 1992). Even worse, significant parts of the discussion are somewhat confused. This paper makes a start on clarifying what I think ought to be the central issues in debates about nonconceptual content. I begin in §1 by pointing out how narrowly focused contemporary discussion is relative to Evans’s original discussion. We are not making as much use as we should of nonconceptual content as a tool for understanding subpersonal information processing and the complexities of its status relative to perception and thought at the personal level. In §2 I turn to what is the central focus of contemporary discussion, namely, the content of perception and identify a “master argument” for nonconceptualism based on the relation between conceptual capacities and capacities for perceptual discrimination. The aim of §3 is to clarify the relation between the claim that perception has nonconceptual content and some superficially similar claims discussed by philosophers of perception. Finally, in §4 I explain why the attention recently focused on what is sometimes called the state version of the nonconceptualist thesis seems to me to be misdirected. (shrink)

Dreaming is often characterized as lacking high-order cognitive skills. In two studies, we test the alternative hypothesis that the dreaming mind is highly similar to the waking mind. Multiple experience samples were obtained from late-night REM sleep and waking, following a systematic protocol described in Kahan . Results indicated that reported dreaming and waking experiences are surprisingly similar in their cognitive and sensory qualities. Concurrently, ratings of dreaming and waking experiences were markedly different on questions of general reality orientation and (...) logical organization . Consistent with other recent studies , experiences sampled from dreaming and waking were more similar with respect to their process features than with respect to their structural features. (shrink)

Metacognition is often defined as thinking about thinking. It is exemplified in all the activities through which one tries to predict and evaluate one’s own mental dispositions, states and properties for their cognitive adequacy. This article discusses the view that metacognition has metarepresentational structure. Properties such as causal contiguity, epistemic transparency and procedural reflexivity are present in metacognition but missing in metarepresentation, while open-ended recursivity and inferential promiscuity only occur in metarepresentation. It is concluded that, although metarepresentations can redescribe metacognitive (...) contents, metacognition and metarepresentation are functionally distinct. (shrink)

In recent years, a debate concerning the nature of knowing-how has emerged between intellectualists who claim that knowledge-how is reducible to knowledge-that and anti-intellectualists who claim that knowledge-how comprises a unique and irreducible knowledge category. The arguments between these two camps have clustered largely around two issues: intellectualists object to Gilbert Ryle's assertion that knowing-how is a kind of ability, and anti-intellectualists take issue with Jason Stanley and Timothy Williamson's positive, intellectualist account of knowing-how. Like most anti-intellectualists, in this paper (...) I will raise objections to Stanley and Williamson's account of knowing-how and also defend the claim that ability is necessary for knowing-how attributions. Unlike most discussions of knowing-how, however, I will return to more Rylean considerations in order to illustrate that any intellectualist account of knowing-how, not simply Stanley and Williamson's preferred variety, will fail because it will be unable to account for fundamental differences in the knowledge required to instantiate an ability and the knowledge involved in propositional thought.

Philosophers have often argued that ascriptions of content are appropriate only to the personal level states of folk psychology. Against this, this paper defends the view that the familiar propositional attitudes and states defined over them are part of a larger set of cognitive proceses that do not make constitutive reference to concept possession. It does this by showing that states with nonconceptual content exist both in perceptual experience and in subpersonal information-processing systems. What makes these states content-involving is their (...) satisfaction of certain basic conditions deriving from a general account of representation-driven behaviour that is neutral on the question of concept possession. It is also argued that creatures can be in states with nonconceptual content even though they possess no conceptual abilities at all. (shrink)

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

The article offers a close reading of the famous upanişadic story of Indra, Virocana and Prajāpati from the eighth chapter of the Chāndogya-Upanişad versus Śankara’s bhāşya, with special reference to the notions of suşupti and turīya. That Śankara is not always loyal to the Upanişadic texts is a well-known fact. That the Upanişads are (too) often read through Śan-kara’s Advaitic eyes is also known. The following lines will not merely illustrate the gap between text and commentary but will also reveal (...) an unexpected Upanişadic depiction of ‘dreamless sleep’ and ‘transcendental consciousness’. Suşupti is described here as ‘one step too far’, as a ‘break’ or discontinuity in one’s consciousness; whereas turīya is depicted positively, and surprisingly even in wordly terms. Unlike the third state of consciousness in which there is no ‘world’ nor ‘me’, and which is described through Indra’s character as ‘total destruction’ (vināśa); in turīya, the world ‘comes back’, or rather the ‘renouncer’ returns to the world. Sankara’s position, as far as the story under discussion is concerned, is radically different. For him, the Upanişadic story illustrates the continuity of consciousness in all its states. For him, the identification with merely one of the consciousness-states is an error (adhyāsa) which causes suffering. Consciousness prevails even in suşupti, and turīya has nothing to do with ‘coming back to the world’, since there is nowhere to come back from or to. Turīya, as seen by the Advaitin, consists of all the other states of consciousness together, or as K. C. Bhattacharyya puts it, ‘It is not only a stage among stages; it is the truth of the other stages’. (shrink)

From the neurophysiological perspective, thinking in dreaming and the quality of dream thought have been considered hallucinatory, bizarre, illogical, improbable, or even impossible. This empirical phenomenological research concentrates on testing whether dream thought can be defined as rational in the sense of an intervening mental process between sensory perception and the creation of meaning, leading to a conclusion or to taking action. From 10 individual dream journals of male participants aged 22–59 years and female participants aged 25–49 years, we delimited (...) four dreams per journal and randomly selected five thought units from each dream for scoring. The units provided a base for testing a hypothesis that the thought processes of dream construction are rational. The results support the hypothesis and demonstrate that eight fundamental rational thought processes can be applied to the dreaming process. (shrink)

Dream lucidity, or being aware that one is dreaming while dreaming, is not an all-or-none phenomenon. Often, subjects report being some variant of “a little lucid” as opposed to completely or not at all. As recent neuroimaging work begins to elucidate the neural underpinnings of lucid experience, understanding subtle phenomenological variation within lucid dreams is essential. Here, we focus on the variability of lucid experience by asking participants to report their awareness of the dream on a 5-point Likert scale. Participants (...) implemented a combination of mnemonic training lucid dream induction methods at home for one week and provided detailed reports about their dream experiences each morning. Consistent with previous research, cognitive induction methods led to about half of participants reporting at least one lucid dream and about half of all dreams including some level of lucidity. However, we also show that induction success rate varies significantly depending on the minimum criteria for lucidity. Participants also reported how much they adhered to specific components of each induction method, and the amount of mnemonic rehearsal during a brief early awake period was predictive of lucidity level. Furthermore, lucidity levels were positively correlated with dream control, dream bizarreness, and next-morning positive affect. Lastly, we asked participants open-ended questions about why they chose particular levels of lucidity. We focus a qualitative discussion on responses to those “semi-lucid” dreams to explore why participants rate their dreams as having intermediate levels of awareness. Together, the present study explores the frequency of semi-lucid dreams, what they are, why they might arise, their correlates, and how they impact methodological concerns in lucid dreaming research.
