In the final years of his life, the Belgian phenomenologist Marc Richir started to question if philosophical writing would become pointless when artists, great poets for example, have already achieved so well what philosophers have always aspired to achieve. There is no doubt that Richir considers himself in alliance with artists, since he basically believes that “phenomenology is trying to say the same thing as poets or musicians, or even possibly painters, but with philosophical language”. He seems thereby to imply (...) that phenomenology is destined to become self-aware as a sort of art. There is no surprise in this regard if we notice how frequently, throughout his entire career of philosophical production, he employs the Kantian term of the sublime to express what constitutes the phenomenon as nothing but phenomenon. This article goes through his phenomenological interpretation of Kantian aesthetics, his elaboration of the affinity between phenomenology and art, and then his genealogical conception of art, in order to introduce an original thought on what he calls “the moment of the sublime”.

(equal contribution) In this paper, we examine the claim that our intense emotional responses to dreams support the view that dreams are not imaginations but are rather hallucinations that we believe to be real while they are occurring. Dream emotions have been used as evidence that dreams are not imaginations since imaginations should not evoke these kinds of responses. However, we argue that while, in general, a realistic scenario will likely evoke a more intense emotional response than (...) the same imagined scenario, intense emotions can be evoked by imagination in certain circumstances. Thus, intense dream emotions do not prima facie substantiate the intuition that dreams are hallucinations. Nonetheless, dream emotions have features that are not easily accounted for by either the imagination or the hallucination models of dreaming, such as flagrantly unfitting emotions. Our analysis leads us to conclude that dream emotions are highly varied, encompassing certain resemblances to imagination emotions without being solely confined to them. (shrink)

The Dreaming Mind provides an insightful, interdisciplinary approach to the study of dreaming, exploring its nature and examining some of the implications of dream states for theories of consciousness, cognition and the self. Offering an integrative approach into our understanding of dreams and the mind, it is essential reading for students and researchers of consciousness, dreams, philosophy and cognitive sciences, as well as anyone who is curious about dreaming.

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

A comprehensive proposal for a conceptual framework for describing conscious experience in dreams, integrating philosophy of mind, sleep and dream research, and interdisciplinary consciousness studies. Dreams, conceived as conscious experience or phenomenal states during sleep, offer an important contrast condition for theories of consciousness and the self. Yet, although there is a wealth of empirical research on sleep and dreaming, its potential contribution to consciousness research and philosophy of mind is largely overlooked. This might be due, in part, (...) to a lack of conceptual clarity and an underlying disagreement about the nature of the phenomenon of dreaming itself. In Dreaming, Jennifer Windt lays the groundwork for solving this problem. She develops a conceptual framework describing not only what it means to say that dreams are conscious experiences but also how to locate dreams relative to such concepts as perception, hallucination, and imagination, as well as thinking, knowledge, belief, deception, and self-consciousness. Arguing that a conceptual framework must be not only conceptually sound but also phenomenologically plausible and carefully informed by neuroscientific research, Windt integrates her review of philosophical work on dreaming, both historical and contemporary, with a survey of the most important empirical findings. This allows her to work toward a systematic and comprehensive new theoretical understanding of dreaming informed by a critical reading of contemporary research findings. Windt's account demonstrates that a philosophical analysis of the concept of dreaming can provide an important enrichment and extension to the conceptual repertoire of discussions of consciousness and the self and raises new questions for future research.

Dreams are a remarkable experiment in psychology and neuroscience, conducted every night in every sleeping person. They show that the human brain, disconnected from the environment, can generate an entire world of conscious experiences by itself. Content analysis and developmental studies have promoted understanding of dream phenomenology. In parallel, brain lesion studies, functional imaging and neurophysiology have advanced current knowledge of the neural basis of dreaming. It is now possible to start integrating these two strands of research to address (...) fundamental questions that dreams pose for cognitive neuroscience: how conscious experiences in sleep relate to underlying brain activity; why the dreamer is largely disconnected from the environment; and whether dreaming is more closely related to mental imagery or to perception.

This was the first cross-over book into the history of science written by an historian of economics. It shows how 'history of technology' can be integrated with the history of economic ideas. The analysis combines Cold War history with the history of postwar economics in America and later elsewhere, revealing that the Pax Americana had much to do with abstruse and formal doctrines such as linear programming and game theory. It links the literature on 'cyborg' to economics, an element missing (...) in literature to date. The treatment further calls into question the idea that economics has been immune to postmodern currents, arguing that neoclassical economics has participated in the deconstruction of the integral 'self'. Finally, it argues for an alliance of computational and institutional themes, and challenges the widespread impression that there is nothing else besides American neoclassical economic theory left standing after the demise of Marxism.

As a topic in the philosophy of psychology, dreaming is a fascinating, diverse, and severely underdeveloped area of study. The topic excites intense public interest in its own right, while also challenging our confidence that we know what the words “conscious” and “consciousness” mean. So dreaming should be at the forefront of our interdisciplinary investigations: theories of mind which fail to address the topic are incomplete. This chapter illustrates the tight links between conceptual and empirical issues by highlighting surprisingly deep (...) disagreements among leading dream scientists over what might seem basic aspects of their topic.

Sleep researchers in different disciplines disagree about how fully dreaming can be explained in terms of brain physiology. Debate has focused on whether REM sleep dreaming is qualitatively different from nonREM (NREM) sleep and waking. A review of psychophysiological studies shows clear quantitative differences between REM and NREM mentation and between REM and waking mentation. Recent neuroimaging and neurophysiological studies also differentiate REM, NREM, and waking in features with phenomenological implications. Both evidence and theory suggest that there are isomorphisms between (...) the phenomenology and the physiology of dreams. We present a three-dimensional model with specific examples from normally and abnormally changing conscious states. Key Words: consciousness; dreaming; neuroimaging; neuromodulation; NREM; phenomenology; qualia; REM; sleep. (shrink)

When we dream, we feel emotions in response to objects and events that exist only in the dream. One key question is whether these emotions can be said to be “essentially unfitting”, that is, always inappropriate to the evoking scenario. However, how we evaluate dream emotions for fittingness may depend on the model of dreams we adopt: the imagination or the hallucination model. If fittingness requires a match between emotion and evaluative properties of objects or events, it is prima (...) facie plausible that dream emotions could fail to fit under the imagination model because it is unfitting to have an emotion toward an object we do not believe to be real. Under the hallucination model, dream emotions could be unfitting because their objects do not exist but we believe them to be real. More nuance, however, is required. By comparing dream emotions with the emotions we experience while imagining, engaging with fiction, and hallucinating, we conclude that although there are compelling arguments in support of the claim that dream emotions are essentially unfitting, these arguments are not entirely convincing, and it is more plausible that particular dream emotions can be assessed for fittingness under either model of dreaming.

In Dreaming Souls, Owen Flanagan provides both an accessible survey of the latest research on sleep and dreams and a compelling new theory about the nature and function of dreaming. Flanagan argues that while sleep has a clear biological function and adaptive value, dreams are merely side effects, 'free-riders', irrelevant from an evolutionary point of view. But dreams are hardly unimportant. Indeed, Flanagan argues that dreams are self-expressive, the result of our need to find or create (...) meaning, even when we are sleeping. (shrink)

In this paper I develop the thesis that dreams are essential to an understanding of waking consciousness. In the first part I argue in opposition to the philosophers Malcolm and Dennett that empirical evidence now shows dreams to be real conscious experiences. In the second part, three questions concerning consciousness research are addressed. (1) How do we isolate the system to be explained (consciousness) from other systems? (2) How do we describe the system thus isolated? (3) How do (...) we reveal the mechanisms on which this system is based? I suggest that empirical dream research combined with other empirical approaches can help us to sketch answers to all of these questions. I argue that the subjective form of dreams reveals the subjective, macro-level form of consciousness in general and that both dreams and the everyday phenomenal world may be thought of as constructed “virtual realities”. A major task for empirical consciousness research is to find out the mechanisms which bind this experienced world into a coherent whole. (shrink)

This work is designed to make Aristotle's neglected but fascinating writings on sleep and dreams accessible in translation to modern readers, and to provide a commentary with a contemporary perspective. It considers Aristotle's theory of dreams in historical context, especially in relation to Plato. It also discusses neo-Freudian interpretations of Aristotle and contemporary experimental psychology of dreaming. Aristotle's account of dreaming as a function of the imagination is examined from a philosophical perspective. The work is a revised and (...) corrected version of the North American edition.

In Meditations on First Philosophy, René Descartes argues that one cannot trust one’s senses since they are not a reliable source of obtaining knowledge of the world. One of Descartes’s main contentions to support such an argument is from his explanation of dreams, where one can feel one is awake but instead one is dreaming. Native Americans, however, may argue that the experiences one has in dreams are real and are a source of knowledge of the real world. (...) Although Descartes uses dreams to support his argument, some Native Americans have a different take on dreams. Dreams for Native Americans are a source of knowledge as well as a source for obtaining one’s identity. Gregory Cajete, in American Indian Thought, notes that “Dreams and Visions are a natural means for accessing knowledge and establishing relationship to the world. They are encouraged and facilitated.” In other words, it is through dreams that individuals are guided, destined, and informed. Therefore, dreams as understood by some Native Americans are an extension of reality that anticipate events that will happen or can happen. The focus of this paper is an exploration of the philosophical and religious epistemology pertaining to Native Americans as described in their accounts of dreams. (shrink)

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)

Andrew Baxter is a generally overlooked philosopher of the first half of the eighteenth century, known almost exclusively for his critique of Berkeleyan idealism. In this paper, I show that he was much more than just a critic of his immediate predecessors, by setting out his undeservedly ignored theory of dreaming and demonstrating its depth, originality as well as its potential to challenge his peers. I begin by highlighting the unprecedented richness of his account, focusing on the passivity, uniqueness and (...) epistemic significance of dreams. Underpinned by an idiosyncratic causal explanation, Baxter’s theory of dreams is not only original, but also allows him to clearly distinguish dreaming from related but importantly different phenomena, especially imagination. This is a remarkable improvement on the more coarse-grained faculty psychology of his immediate predecessors. Moreover, Baxter’s account of dreaming also points to the difficulties, generally glossed over in scholarship, in Locke and Berkeley’s attempt to lump dreaming and imagination together. In particular, their apparent view that dreams are caused in the same way as ideas of imagination threatens to undermine their commitment to mental transparency and the validity of self-consciousness. Finally, I consider some possible Berkeleyan responses that draw on Baxterian considerations and distinctions. (shrink)

Rene Descartes's motto challenges his would-be historians: "He lives well who hides well." He hid even in the Discourse on Method, where he professed to recount the story of his "entire life, " but said almost nothing about his childhood and youth. He mentioned neither family nor friends, and he boasted a total freedom from irrational passions. In the Discourse, which presented a new way of achieving certain truth through mathematical reason, Descartes stressed just one event, a day of thinking (...) at the beginning of winter, 1619. Tucked away in an unpublished notebook, however, Descartes also left the Olympica, which documented the wildly irrational dreams he had the night of November 10, 1619, and gave his own enthusiastic interpretations. Embarrassed scholars have tried to reason away this record and even the dreams themselves. Adapting clinical methods to historical research, John Cole offers the first systematic interpretation of the Olympian dreams. He argues that they expressed and masked Descartes's unresolved conflicts: his guilt at having rejected the law career for which he had been trained and which his lawyer father had wanted him to pursue, and his shame over early failures to satisfy the high expectations of his friend and mentor, Isaac Beeckman. Cole shows us how a critical historian can make sense of such irrational material and lets us see the creation of an egocentric and rationalist philosophy. (shrink)

Dreams are a complex phenomenon which the philosophical field knows very little about. However, scientists like Freud or Jung, were able to prove that dream interpretation brings different advantages to our lives. For that reason, the purpose of this paper is to demonstrate that dreams, when understood, can offer us a new life perspective, especially in difficult times. Therefore, with the help of an innovative phenomenological approach introduced by Maria Zambrano, which focuses on the form of the dream (...) and its relation with time perception, rather than the dream content, we are going to observe that people have many types of consciousness, as well as different forms of access to time which relate to multiple perception modes and emotional states. Applying this theory, Maria J. Neves, is able to demonstrate that a phenomenological dream analysis can produce significant changes in peoples’ lives. (shrink)

Unpleasant dreams occur much more frequently than many people realise. If one is a hedonistic utilitarian – or, at least, one thinks that dreams have positive or negative moral value in virtue of their experiential quality – then one has considerable reason to try to make such dreams more positive. Given it is possible to improve the quality of our dreams, we ought to be promoting and implementing currently available interventions that improve our dream experiences, and (...) conducting research to find new, more effective interventions.

Freud's account of dreams has a cogent interpretive basis.

DREAM complexes are transcriptional regulators that control the expression of hundreds to thousands of target genes involved in the cell cycle, quiescence, differentiation, and apoptosis. These complexes contain many subunits that can vary according to the considered target genes. Depending on their composition and the nature of the partners they recruit, DREAM complexes control gene expression through diverse mechanisms, including chromatin remodeling, transcription cofactor and factor recruitment at various genomic binding sites. This complexity is particularly high in mammals. Since the (...) discovery of the first dREAM complex (drosophila Rb, E2F, and Myb) in Drosophila melanogaster, model organisms such as Caenorhabditis elegans, and plants allowed a deeper understanding of the processes regulated by DREAM‐like complexes. Here, we review the conservation of these complexes. We discuss the contribution of model organisms to the study of DREAM‐mediated transcriptional regulatory mechanisms and their relevance in characterizing novel activities of DREAM complexes.

In lucid dreams the dreamer is aware of dreaming and often able to influence the ongoing dream content. Lucid dreaming is a learnable skill and a variety of techniques is suggested for lucid dreaming induction. This systematic review evaluated the evidence for the effectiveness of induction techniques. A comprehensive literature search was carried out in biomedical databases and specific resources. Thirty-five studies were included in the analysis , of which 26 employed cognitive techniques, 11 external stimulation and one drug (...) application. The methodological quality of the included studies was relatively low. None of the induction techniques were verified to induce lucid dreams reliably and consistently, although some of them look promising. On the basis of the reviewed studies, a taxonomy of lucid dream induction methods is presented. Several methodological issues are discussed and further directions for future studies are proposed.

"An accessible survey of the latest research on sleep and dreams and a compelling new theory about the nature and function of dreaming."--Jacket.

Dreams of chase or pursuit, falling, sex, flying, nudity, failing an examination, one's own and other's death, fire, teeth falling out and some other themes experienced, even if only rarely, by many people all over the world have been labelled 'typical dreams'. This essay argues that typical dreaming, rather a syndrome of themes than monothematic, reflects an extraordinary state of mind and brain. Odd and particularly memorable perceptions, as well as emerging awareness of sleep and dreaming -- i.e. (...) parallels to lucid dreaming, sleep paralysis, complex partial seizure, epileptic and migraine auras, and aspects of dreaming after trauma -- can be traced with some plausibility in all prominent variants of typical dreaming. When viewed from this perspective, for example, dream pursuers are much more a shadow of the bodily self than a metaphor for the psycho- biographical situation or evolutionarily implemented sparring partners who make dreamers fit for the struggle for survival during waking hours.

I argue that dreams can contain perceptual elements in multifarious, heretofore unthought-of ways. I also explain the difference between dreams that contain perceptual elements, perceptual experiences that contain dream elements, and having a dream and a perceptual experience simultaneously. I then discuss two applications of the resulting view. First, I explain how my taxonomy of perception in dreams will allow “dream engineers”—who try to alter the content of people’s dreams—to accurately classify different dreams and explore (...) creating new forms of perception in dreams. Second, I consider the consequences of the view for the role of memory in dreaming and imagination. I argue that not every element of dreams or sensory imaginations must rely on memory. The resultant view of sensory imagination provides a counterexample to Hume’s account of sensory imagination, according to which sensory imagination must be built up from faint copies of sensory impressions stored in memory.

The paradigmatic assumption that REM sleep is the physiological equivalent of dreaming is in need of fundamental revision. A mounting body of evidence suggests that dreaming and REM sleep are dissociable states, and that dreaming is controlled by forebrain mechanisms. Recent neuropsychological, radiological, and pharmacological findings suggest that the cholinergic brain stem mechanisms that control the REM state can only generate the psychological phenomena of dreaming through the mediation of a second, probably dopaminergic, forebrain mechanism. The latter mechanism (and thus (...) dreaming itself) can also be activated by a variety of nonREM triggers. Dreaming can be manipulated by dopamine agonists and antagonists with no concomitant change in REM frequency, duration, and density. Dreaming can also be induced by focal forebrain stimulation and by complex partial (forebrain) seizures during nonREM sleep, when the involvement of brainstem REM mechanisms is precluded. Likewise, dreaming is obliterated by focal lesions along a specific (probably dopaminergic) forebrain pathway, and these lesions do not have any appreciable effects on REM frequency, duration, and density. These findings suggest that the forebrain mechanism in question is the final common path to dreaming and that the brainstem oscillator that controls the REM state is just one of the many arousal triggers that can activate this forebrain mechanism. The “REM-on” mechanism (like its various NREM equivalents) therefore stands outside the dream process itself, which is mediated by an independent, forebrain “dream-on” mechanism. Key Words: acetylcholine; brainstem; dopamine; dreaming; forebrain; NREM; REM; sleep. (shrink)

This edited volume is the first systematic philosophical investigation of the complex and multifarious relationships between dreaming and memory. Featuring fifteen contributions by leading researchers, it explores a range of issues that arise when dreaming and memory are considered together. What does one remember when one remembers what one dreamt, and what is it for a memory of a dream to be accurate? What are the phenomenological, cognitive, and epistemic similarities and dissimilarities between dreaming and remembering? How does the self (...) figure in dreams and memories? The book will serve as an indispensable resource both for philosophers interested in dreaming or memory and for their philosophically-minded colleagues in empirical disciplines and will provide an invaluable starting point for advanced students in need of a snapshot of the state of the art in philosophical research on dreaming and memory.

Full-Blooded religion is not acceptable in mainstream bioethics. This article excavates the cultural history that led to the suppression of religion in bioethics. Bioethicists typically fall into one of the following camps. 1) The irreligious, who advocate for suppressing religion, as do Timothy F. Murphy, Sam Harris, and Richard Dawkins. This irreligious camp assumes American Fundamentalist Protestantism is the real substance of all religions. 2) Religious bioethicists, who defend religion by emphasizing its functions and diminishing its metaphysical commitments. Religious defenders (...) empty religion of its theology to present its feel-good functions in a way that is acceptable to the irreligious. However, religion reduced to its functions dissolves into a counter-culture that may counteract materialism but lacks the power to motivate much more. This article criticizes both camps, as both presume Enlightenment myths and consequently neuter religion. Both irreligious and religious bioethicists commonly presume Enlightenment myths about secularity and religion. Secularity is presumed neutral and rational. Religion is presumed divisive and irrational. This myth provides built-in value-judgements; we have already judged secularity as good and religion as bad. Much of the debate over religion in bioethics is arguing over false stereotypes of religion. Consequently, mainstream bioethics neuters religion, while the irreligious are gifted political power to define the field. (shrink)

Dreams are often defined as sleeping experiences with phenomenal character similar to perceptions of the real world. Hence they pose a prima facie challenge to accounts of phenomenal character in terms of acquaintance relations. One response is disjunctivist: to give a different account of their phenomenal character from that of successful perceivings. I argue that, given the alleged frequency of dreaming on the standard model, this disjunctivist approach weakens the explanatory value of the acquaintance account of the phenomenal character (...) of successful perceivings. Another response is to follow Malcolm and Dennett in denying that dreaming has phenomenal character at all. I present a cultural-social model of dreams and argue that we lack theory-neutral evidence of the phenomenal character of dreams and thus it is legitimate to choose between theories of dreaming on the basis of their fit with our best theory of the phenomenal character of successful perceivings, namely acquaintance.

Systemic discrimination produces individuals with a degraded self-concept who therefore may not care about autonomy or set ends compatible with human flourishing. Under systemic discrimination, the dominant conceptual and evaluative framework does not enable the oppressed to articulate their humanity or the rationality of aspiring to full human flourishing. And the injustice of that system may be fully visible only from a perspective outside of that system.

This article reviews recent findings indicating some common brain processes during dissociative states and dreaming with the aim to outline a perspective that neural chaotic states during dreaming can be closely related to dissociative states that may manifest in dreams scenery.

I offer a novel reading in this dissertation of René Descartes’s (1596–1650) skepticism in his work Meditations on First Philosophy (1641–1642). I specifically aim to answer the following problem: How is Descartes’s skepticism to be read in accordance with the rest of his philosophy? This problem can be divided into two more general questions in Descartes scholarship: How is skepticism utilized in the Meditations, and what are its intentions and relation to the preceding philosophical tradition? -/- I approach the topic (...) from both a historical and a text-based analysis, combining textual and contextual research. I examine Descartes’s skepticism against two main traditions in the historical analysis: philosophical skepticism and Aristotelian Scholasticism. I argue that skepticism in the Meditations is intended to oppose and upheave both Scholasticism and skepticism. The intended results of the work are not merely epistemological but also metaphysical and even ethical. Furthermore, these ambitions cannot be neatly distinguished but merge into each other. -/- The third historical context against which the skeptical meditations are examined is the literary genre of meditative exercises, particularly from the 1500–1600’s, which, while religiously and spiritually oriented, likewise provided the practitioner with an enlightened understanding of self-knowledge and their cognitive place in the world on the way to closer spiritual proximity to God. I argue by this reading that the skepticism of the Meditations is an attentive, meditational cognitive exercise that is not merely instrumental and methodological but is to have a genuine and serious (psychologically real) effect on our thinking. The skeptical meditation is not simply a theoretical thought experiment but is to be seriously practiced as a transformative process of reorienting one’s cognitive framework to discover truth, certainty, and a way to a happy, tranquil, and virtuous life. -/- I offer a close reading in the textual analysis of the first three meditations of the Meditations. I argue that the meditative skepticism employed in the work does not reject the previous beliefs but suspends judgment on them, withdrawing assent until further evidence can be found. I introduce a new term into Descartes scholarship in this analysis, based on the terminology of ancient skepticism: Cartesian epochē (gr. epochē, suspension, withdrawal). Instead of rejecting previous beliefs or assenting to the probably false, the skeptical procedure of the Meditations is argued to emulate in important ways the suspension of judgment on equally balanced reasons in ancient Pyrrhonian skepticism. Novel interpretations are presented along the way of the will’s freedom, of the First Meditation’s skeptical scenarios, of the cogito, and of the vindication of metaphysical certainty, as well as a clarification of the Cartesian Circle problem. -/- Reinterpreting the relation of Descartes’s skepticism to the preceding historical and literary traditions leads to a new look at the skeptical method itself. Presenting a new interpretation of skepticism in the Meditations leads at the same time to a new look at its relation to the historical context. The two research questions are, then, intrinsically tied together. -/- My focus in the study is on the Meditations, but I also reference and discuss Descartes’s other philosophical works, as well as his correspondence, when necessary.

Lucid dreaming refers to a dream state characterized by the dreamers awareness of being in a dream and being able to volitionally control its content. The aim of this study was to find neurophysiological evidence for the 7 criteria of lucid dreaming proposed by Paul Tholey. Each of the criteria was analyzed separately with regard to its underlying neurocircuits. We hypothesized that not one, but many regions are involved in the state of lucid dreaming. Our results have shown a satisfactory (...) overlap of the theoretical components and the brain regions activated during a lucid dream. During lucid dreaming, a brain network seems to emerge, that is more than the sum of its parts. Further research is needed to understand the psychoneurological underpinnings of lucid dreams.

Cognitive theories claim, whereas non-cognitive theories deny, that cognitive access is constitutive of phenomenology. Evidence in favor of non-cognitive theories has recently been collected by Block and is based on the high capacity of participants in partial-report experiments compared to the capacity of the working memory. In reply, defenders of cognitive theories have searched for alternative interpretations of such results that make visual awareness compatible with the capacity of the working memory; and so the conclusions of such experiments remain controversial. (...) Instead of entering the debate between alternative interpretations of partial-report experiments, this paper offers an alternative line of research that could settle the discussion between cognitive and non-cognitive theories of consciousness. Here I relate the neural correlates of cognitive access to empirical research into the neurophysiology of dreams; cognitive access seems to depend on the activity of the dorsolateral prefrontal cortex. However, that area is strongly deactivated during sleep; a period when we entertain conscious experiences: dreams. This approach also avoids the classic objection that consciousness should be inextricably tied to reportability or it would fall outside the realm of science. (shrink)

The conscious experiences we have during sleep have the potential to improve our empathetic response to those who experience delusions and psychosis by supplying a virtual reality simulation of mental illness. Empathy for those with mental illness is lacking and there has been little improvement in the last decades despite efforts made to increase awareness. Our lack of empathy, in this case, may be due to an inability to accurately mentally simulate what it’s like to have a particular cognitive disorder. (...) Dreaming can help mitigate these deficits by placing the dreamer directly into a realistic virtual simulation and thus increase their capacity for empathy. Increasing empathy would go some way towards reducing the stigma and discrimination faced by people in this group. Recent work suggests that virtual reality can increase empathy towards a variety of marginalised groups, however, this technology is limited in its ability to simulate mental illnesses such as delusions. Dreams, however, are at times virtual reality delusion simulators. They can replicate, to a reasonable degree, delusions and psychosis, and through these experiences, we can learn ‘what it’s like’ to have these conditions. It is essential that we recognise these experiences for what they are, attempt to remember and reflect on them. Instead of disregarding dreams due to their unusualness and bizarreness, we can learn from these experiences and expand our understanding of the human condition and its many forms. (shrink)

That conception is orthodox in today’s common sense and also historically. Presupposed by Plato, Augustine, and Descartes, it underlies familiar skeptical paradoxes. Similar orthodoxy is also found in our developing science of sleep and dreaming.[2] Despite such confluence.

The article argues that our concepts are deeply rooted in the architecture of visual processing. The argument is based on evidence provided by two seemingly very distant theories of mind together with two sorts of corresponding visions: Freud’s theory of dreams, which suggests oneiric visions represent our thoughts and the mechanical model of the mind developed in the context of computer science. As will be argued, Freud’s findings are in fact supported by advances in this field, in particular by (...) deep convolutional neural networks (DCNNs) which mirror the activity of visual cortex, producing visions strikingly similar to dreams. An in-depth analysis of such images, supported by insights from empiricism and conceptual metaphor theory, reveals that they represent visual universals, as well as more fragmentary notions pertaining to features, and complete abstractions, such as those found in language and in mathematics. This finding points towards a more comprehensive thesis about the links of vision to reflection: the crucial insight that will be developed and defended in this article is that the architecture of visual processing is the basis of the conceptual structures that underpin cognition.
