This paper critically evaluates an objection to introspective arguments for human freedom found within Spinoza's Ethics. The objection-- which we call Spinoza's dream argument -- challenges the evidentiary value of a person's experience of her own freedom by pointing out that some choices made within dreams are experienced as no less free than choices made while awake despite the fact that choices made within dreams are not free. After reconstructing Spinoza's dream argument, we critically evaluate it, (...) concluding ultimately that it fails in two respects. First, we draw upon the results of an experiment we conducted that suggests that dreamt choices are not experienced as free to the same extent as choices made while awake. Second, we argue that there is no compelling justification for the claim that choices made within dreams are not free. (shrink)

According to one fairly standard reconstruction Descartes' Dream Argument has two crucial premises. The paper starts by analysing two important failed attempts, discussed by Barry Stroud and Mark Steiner, at justifying one of these premises. On this basis then an alternative is suggested to the line of interpretation assumed by these attempts which easily resolves the problems they face. It is shown that this alternative and its rivals are on a par with respect to the other crucial premise (...) of the Dream Argument and that it is superior to the others in avoiding scepticism or infinite regress.

In his recent work, The Significance of Philosophical Scepticism, Barry Stroud proposes to carry out an in-depth critique of the attempt by philosophers to invalidate all knowledge of an external world on the basis of Descartes' dream argument. His more particular aims in this endeavour are to uncover significant features of any such scepticism and to disclose in the process fundamental aspects of ‘human knowledge’ itself. Thus, among other features of knowledge that his study discloses, he thinks, is, (...) echoing Kant, the idea ‘that a completely general distinction between everything we get through the senses, on the one hand, and what is true or not true of the external world, on the other, would cut us off forever from knowledge of the world around us.’ And a significant feature of Cartesian dream scepticism he believes to have uncovered is that its ‘effectiveness’ rests upon the philosopher's traditional assumption of an objectively existent world that is understandable ‘from a detached “external” viewpoint.’.

1. Introduction. Can Berkeleian idealism draw any support from the following argument?

In this paper, I argue that dreaming arguments are no cause for alarm.

Ernest Sosa has proposed at least three responses to the dream argument for skepticism in his writings in the past decade. The first and the main purpose of this paper is to critically examine the three Sosaian responses, as well as a Wittgensteinian response Sosa would endorse, by investigating whether they can refute the six different versions of the dream argument found in a passage in the Zhuangzi. The second purpose of this paper is exactly to (...) offer an exposition of the passage in the Zhuangzi so as to show that there were already sophisticated versions of the dream argument in ancient China. The main results of the critical examination are as follows. For four of the six versions of the dream argument found in the Zhuangzi, each of them can be refuted by either the Wittgensteinian response or one of the three Sosaian responses. With respect to the remaining two versions of the dream argument, one of them can be refuted partially by two of Sosa’s responses. First, that version of the dream argument can be refuted by one of Sosa’s responses, provided the imagination model of dreaming is adopted. Second, it can also be refuted by another of Sosa’s responses without assuming the imagination model of dreaming, though both the view that there is unsafe knowledge and a certain externalist reliabilism need to be adopted. However, another of the two remaining versions of the dream argument cannot be refuted by any of the Sosaian responses, nor the Wittgensteinian response. This shows that the three Sosaian responses and the Wittgensteinian response cannot refute significantly many different versions of the dream argument. Sosa’s responses, including the Wittgensteinian response, therefore are not in general successful in the refutation of he dream argument for skepticism. (shrink)

This paper appeals to the phenomenon of dreaming to provide a novel defense against arguments from evil. The thrust of the argument is as follows: when we wake up after a nightmare we are often filled entirely with relief, and do not consider ourselves to have actually suffered very much at all; and since it is epistemically possible that this whole life is simply a dream, it follows that it is epistemically possible that in reality there is very (...) little suffering. This epistemic possibility decisively undermines a key premise of both logical and evidential arguments from evil. (shrink)

In this article, I offer a detailed examination of Margaret Macdonald's response to the Cartesian sceptical argument from dreaming. I show that Macdonald's views were not well understood by her contemporaries, and I suggest that this misunderstanding has led to her omission from subsequent discussions of this subject. I end with a brief demonstration of the fact that Macdonald's central claims have re-emerged in contemporary epistemology.

Putnam’s semantic argument against the BIV hypothesis and Sosa’s argument against dream skepticism based on the imagination model of dreaming share some important structural features. In both cases the skeptical option is supposed to be excluded because preconditions of its intelligibility are not fulfilled (affirmation and belief in the dream scenario, thought and reference in the BIV scenario). Putnam’s reasoning is usually interpreted differently, as a classic case of deception, but this feature is not essential. I (...) propose to interpret BIV’s utterances as cases of reference failure best captured by truth-value gaps. Both anti-skeptical strategies are then vulnerable to the same type of objections (how do we know what state we are in or how do we know what kind of language do we speak). (shrink)

In this paper, I explore connections between two disciplines not typically linked: argumentation theory and urban design. I first trace historical ties between the art of reasoned discourse and the idea of civic virtue. I next analyze discourse norms implicit in three theories of urban design: Jane Jacobs' The Death and Life of Great American Cities (1961), Christopher Alexander's A Pattern Language: Towns, Buildings, Construction (1977), and Peter Katz's The New Urbanism: Toward an Architecture of Community (1994). I then propose (...) a set of ‘settlement’ issues of potential interest to both urban designers and argumentation theorists: size, density, heterogeneity, publicity, security, and identity. I conclude by suggesting that the ‘good city’ be seen as both a spatial and a discursive entity. From such a perspective, good public discourse is dependent, at least in part, on good public space; and good public space is defined, at least in part, as a context conducive to good public discourse.

The dream argument and its role in Cartesian doubt continue to engage commentators. As recent scholarship shows, a consensus has yet to be attained. In what follows I attempt to resolve the current debate by offering an account of the dream doubt which captures Descartes’s rhetorical strategy in Meditation I. A faithful reading of the text, I propose to show, reveals that the dream doubt is not entertained seriously nor is it proposed merely for the sake (...) of methodological skepticism. It is rather an integral part of a dogmatic intrusion of Cartesian science at a pivotal point in the critique of prescientific experience. After presenting the proposed interpretation, I examine the accounts offered in the current scholarship. (shrink)

A common objection to Sosa’s epistemology is that it countenances, in an objectionable way, unsafe knowledge. This objection, under closer inspection, turns out to be in far worse shape than Sosa’s critics have realised. Sosa and his defenders have offered two central response types to the idea that allowing unsafe knowledge is problematic: one response type adverts to the animal/reflective knowledge distinction that is characteristic of bi-level virtue epistemology. The other less-discussed response type appeals to the threat of dream (...) scepticism, and in particular, to the idea that many of our everyday perceptual beliefs are unsafe through the nearness of the dream possibility. The latter dreaming response to the safety objection to Sosa’s virtue epistemology has largely flown under the radar in contemporary discussions of safety and knowledge. We think that, suitably articulated in view of research in the philosophy and science of dreaming, it has much more going for it than has been appreciated. This paper further develops, beyond what Sosa does himself, the dreaming argument in response to those who think safety (as traditionally understood) is a condition on knowledge and who object to Sosa’s account on the grounds that it fails this condition. The payoffs of further developing this argument will be not only a better understanding of the importance of insights about dreaming against safety as a condition on knowledge, but also some reason to think a weaker safety condition, one that is relativised to SSS (i.e., skill/shape/situation) conditions for competence exercise, gets better results all things considered as an anti-luck codicil on knowledge.

Big dreams are rare but highly memorable dream experiences that make a strong and lasting impact on the dreamer's waking awareness. Moving far beyond "I forgot to study and the finals are today" and other common scenarios, such dreams can include vivid imagery, intense emotions, fantastic characters, and an uncanny sense of being connected to forces beyond one's ordinary dreaming mind. In Big Dreams, Kelly Bulkeley provides the first full-scale cognitive scientific analysis of such dreams, putting forth an original (...) theory about their formation, function, and meaning.Big dreams have played significant roles in religious and cultural history, but because of their infrequent occurrence and fantastical features, they have rarely been studied in light of modern science. We know a great deal about the religious manifestations of big dreams throughout history and around the world, but until now that cross-cultural knowledge has never been integrated with scientific research on their psychological roots in the brain-mind system. In Big Dreams, Bulkeley puts a classic psychological thesis to the scientific test by clarifying and improving it with better data, sharper analysis, and a broader evolutionary framework. He brings evidence from multiple sources, shows patterns of similarity and difference, questions prior assumptions, and provides predictive models that can be applied to new sets of data. The notion of a connection between dreaming and religion has always been intuitively compelling; Big Dreams transforms it into a solid premise of religious studies and brain-mind science. Combining evidence from religious studies, psychology, anthropology, evolutionary biology, and neuroscience, Big Dreams makes a compelling argument that big dreams are a primal wellspring of religious experience. They represent an innate, neurologically hard-wired capacity of our species that regularly provokes greater self-awareness, creativity, and insight into the existential challenges and spiritual potentials of human life.

In her book "descartes", Margaret wilson proposes a new interpretation of the dreaming argument. According to this interpretation, Descartes does not reach his conclusion via a subconclusion that I cannot be certain that I am not dreaming (as was claimed by more traditional authors such as moore, Malcolm, Frankfurt, And walsh), But rather directly, By pointing out that I cannot be certain that waking experience is veridical. The present article examines the arguments supporting wilson's interpretation, And finds them to (...) be faulty. Thus the article's conclusions clearly favor the traditional interpretations mentioned above. (shrink)

The phenomenal character of dreaming has long been a matter of philosophical debates. Most of the time, dreaming is either likened to perception or likened to imagination, in order to decide whether it gets closer to normal or abnormal states of consciousness. This line of debates extends from the traditional dream argument to the contemporary movement of phenomenology. This article presents what specific contributions phenomenology has made to the millennial investigations of dreaming. Its structure is twofold. Firstly, we (...) introduce how pioneering phenomenologists, including Edmund Husserl, Jan Patočka, Jean-Paul Sartre, Eugen Fink, and Jean Héring, analyse the lived characters of dreaming respectively. Secondly, we show that those pioneering phenomenologists, by engaging with the traditional dream argument, have laid out the worldliness of dreams as a crucial criterion for deciding how similar dreams and reality can be.

Does the material basis of conscious experience extend beyond the boundaries of the brain and central nervous system? In Clark 2009 I reviewed a number of ‘enactivist’ arguments for such a view and found none of them compelling. Ward (2012) rejects my analysis on the grounds that the enactivist deploys an essentially world-involving concept of experience that transforms the argumentative landscape in a way that makes the enactivist conclusion inescapable. I present an alternative (prediction-and-generative-model-based) account that neatly accommodates all the (...) positive evidence that Ward cites on behalf of this enactivist conception, and that (I argue) makes richer and more satisfying contact with the full sweep of human experience.

ArgumentThe argument of this paper is to situate The Interpretation of Dreams within an historical context. It is, therefore, impossible to believe Freud entirely when he staged himself in his letters to Fliess as a mere discoverer. In reality Freud also felt he belonged to a learned community of dream specialists, whom I call “dreaming scientists” and “scientific dreamers.” Instead of speaking, as Ellenberger does, in terms of influence, I will be offering as an example a portrait of (...) Freud as a reader of two French authors, Maury, and indirectly, Hervey de Saint-Denys. I will analyze how Freud staged himself as replacing Maury and dreaming sometimes like Hervey de Saint-Denys. My premise in this work is that we must forget Freud, in order to adventure into a learned dream culture peculiar to the nineteenth century. Only afterwards can we come back to Freud and place him in this context as a creative heir. (shrink)

This paper compares the relative merits of perceptual beliefs and introspective beliefs in the context of dream arguments for skepticism. It is argued that introspective beliefs are not epistemically privileged over perceptual beliefs.

Standard accounts of delusion explain them as responses to experience. Cognitive models of feature binding in the face recognition systems explain how experiences of mismatch between feelings of "familiarity" and faces can arise. Similar mismatches arise in phenomena such as déjà and jamais vu in which places and scenes are mismatched to feelings of familiarity. These cognitive models also explain similarities between the phenomenology of these delusions and some dream states which involve mismatch between faces, feelings of familiarity and (...) identities. Given these similarities it makes sense to retain that aspect of the standard account in the face of revisionist arguments that feature binding anomalies which lead to delusions of misidentification are not consciously experienced.

Threat themes are clearly over-represented in dreams. Threat is, however, not the only theme with potential evolutionary significance. Even for hypnagogic and hypnopompic hallucinations during sleep paralysis, for which threat themes are far commoner than for ordinary dreaming, consistent non-threat themes have been reported. Revonsuo's simulation hypothesis represents an encouraging initiative to develop an evolutionary functional approach to dream-related experiences but it could be broadened to include evolutionarily relevant themes beyond threat. It is also suggested that Revonsuo's evolutionary re-interpretation (...) of dreams might profitably be compared to arguments for, and models of, evolutionary functions of play. [Revonsuo]. (shrink)

If my argument here is successful, it will follow that this paper should have been included in the first volume of this series, The Human Agent ; for I want to contend that the topic of dreams belongs to philosophy of mind rather than to theory of knowledge.

For the anti-realist, the truth about a subject's past thoughts and attitudes is determined by what he is subsequently disposed to judge about them. The argument for an anti-realist interpretation of Wittgenstein's view of past-tense statements seems plausible in three cases: dreams, calculating in the head, and thinking. Wittgenstein is indeed an anti-realist about dreaming. His account of calculating in the head suggests anti-realism about the past, but turns out to be essentially realistic. He does not endorse general anti-realism (...) about past thoughts; but his treatment does in some cases involve elements of anti-realism, unacceptable in some instances but possibly correct in others.

As sources of knowledge, perception and testimony are both vulnerable to sceptical arguments. To both arguments a Moorean response is possible: both can be refuted by reference to particular things known by perception and testimony. However, lies and dreams are different possibilities and they are different in a way that undercuts the plausibility of a Moorean response to a scepticism of testimony. The condition placed on testimonial knowledge cannot be trivially satisfied in the way the Moorean would suggest. This has (...) substantial implications for any non-sceptical epistemological theory of testimony. (shrink)

In a recent, and influential, article, Crispin Wright maintains that a familiar form of scepticismwhich finds its core expression in Descartes’ dreaming argumentcan be defused (or, to use Wright’s own parlance, “imploded”), by showing how it employs self-defeating reasoning. I offer two fundamental reasons for rejecting Wright’s ‘implosion’ of scepticism. On the one hand, I argue that, even by Wright’s own lights, it is unclear whether there is a sceptical argument to implode in the first place. On the (...) other, I claim that even on the supposition that Wright has indeed succeeded in setting-up such an argument, he nevertheless fails to follow-through with an adequate response. A diagnosis of the failure of Wright’s approach is then given in the context of the wider sceptical debate. (shrink)

A familiar anti-sceptical response (à la Sosa) to radical sceptical scenarios employs the safety of knowledge. Radical sceptical scenarios are purported to be too modally remote to really threaten knowledge of ordinary propositions. Why? Because knowledge requires safety, and safety requires the target belief to be true in all nearby possible worlds, but radical sceptical scenarios purportedly take place at distant possible worlds. Hence, the safety theorist claims that radical sceptical scenarios don’t challenge our knowledge of ordinary propositions. But it's (...) alleged by Sosa and others that there's one radical sceptical scenario that can’t be dismissed so easily: the dream scenario. After all, unlike evil demons and brains in vats, ‘dreaming is a daily part of our lives…it is too close for comfort’. In this paper, I sketch an argument to the effect that there's good reason to think that the dream of dream scepticism describes a modally remote possibility, in which case I argue that if the safety-based anti-sceptical response is successful against the evil demon sceptical scenario, the brain in a vat sceptical scenario, and other Cartesian sceptical scenarios in this mould, then it's successful against the dream sceptical scenario as well.

J. L. Austin’s attitude towards traditional epistemological problems was largely negative. They arise and are maintained, he charged, by “sleight of hand,” “wile,” “concealed motives,” “seductive fallacies,” fixation on a handful of “jejune examples” and a host of small errors, misinterpretations, and mistakes about matters of fact (1962: 3- 6, 1979: 87). As these charges indicate, he did not offer a general critical theory of traditional epistemological theorizing or of the intellectual motivations that lead to it. Instead, he subjected individual (...) arguments to piecemeal criticism, patiently showing how things go awry in conception, motivation, argumentation, and plain fact. The work was incremental, but the goal was radical: to reduce large edifices to rubble. As he put it regarding certain sense datum theories, “the right policy is to go back to a much earlier stage, and to dismantle the whole doctrine before it gets off the ground” (1962: 142). It is often said that Austin’s criticisms were linguistic, but this is only partly right. While he occasionally charges traditional epistemologists with misusing crucial words and relying on unregulated and inadequately motivated technical terms, he also charges them with factual errors and with distorting or misunderstanding the procedures involved in epistemically evaluating people’s claims and beliefs. For this reason, it is best to see Austin as criticizing traditional epistemological puzzles and projects from the point of view of our ordinary lives (including our best scientific theories and practices). He starts with a commitment to our ordinary ways of using words, our ordinary convictions about.. (shrink)

It is shown that the facts of behavior which Freud sought to encompass by his distinction of Primary and Secondary Process can be formulated in terms of Skinner's system of behavior. This is illustrated by considering the 'primary process' behavior in dreaming, some of whose characteristics according to Freud are: it is illogical and random; visual images predominate in primary process thinking; it is highly charged with affect compared to 'secondary process' thinking; it shows 'condensation' — the fusing together of (...) two or more images into a single image. It is shown that all of these properties can be derived from Skinner's account of behavior. It is then pointed out that both Freud and Skinner have pointed to similar controlling variables of behavior, utilized mainly similar processes, and drawn many of the same distinctions. Implications for contemporary criticisms of Skinner's account of 'thinking' are pointed out. The above is preceded by a preliminary argument that since both Freud and Skinner performed functional analyses of behavior, it should be possible to compare the two accounts if the 'superfluous' middle term — the intrapsychic apparatus — in Freud's account is ignored. It is pointed out that in extrapolating his system to human behavior, Skinner has described in terms of his own system some of the characteristically 'Freudian' facts of behavior, and his formulations on the phenomena of 'repression' are summarized. The Skinnerian formulation of the primary and secondary process distinction is then presented in support of the argument that other facts of behavior which have not been discussed by Skinner can nevertheless be represented within his system of behavior.

In this series of articles, several new hypotheses on sleep and dreaming are presented. In each case, we feel the data do not adequately support the hypothesis. In their lengthy discourse, Hobson et al. represent to us the familiar reciprocal interaction model dressed in new clothes, but expanded beyond reasonable testability. Vertes & Eastman have proposed that REM sleep is not involved in memory consolidation. However, we do not find their arguments persuasive in that limited differences in activity in REM (...) and waking do not lend credence to the idea that memory consolidation occurs in one state and not the other. Solms makes an argument that dreams are generated from the dopaminergic forebrain based largely on pathological lesion studies in humans. We recognize that this argument has some intuitive appeal and agree with some of the tenets but we do not feel that the arguments are completely convincing due to the lack of anatomical controls, including symmetry and laterality. On the whole, there are interesting arguments put forward in these target articles but the evidence does not convince us that new vistas are opened. No Holy Grail of sleep here! [Hobson et al.; Solms; Vertes & Eastman]. (shrink)

Nanotechnology has recently been identified with principles of sustainability and with a ‘green’ agenda generally . Some maintain that this green dream of nanotechnology is a rather ephemeral societal phenomenon that owes its existence to the campaign ploys of politics and business. This paper argues that deeper lying societal and cognitive structures are at work here that complement or even substantiate in some sense the seemingly manipulative saying of a greening of nanotechnologies. Taking seriously the concept of ‘green nano’, (...) this paper examines the common ground between sustainability discourse and the discourse of nanotechnology. Green nanotechnology is understood as a boundary concept in which disparate discourses and concepts join together. The primary concern of the paper is to show that nanodiscourse and ecodiscourse share visions of control and of excess. Both ecotechnology and nanotechnology accept and incorporate arguments about limited growth, and each develops strategies of control—be it through a new-found precision in the control of material flows or through greater efficiency in product design.

In his De Natura et Origine Animae, an answer to a work by Vincentius Victor, Augustine was drawn into attempting to answer some questions about what kind of reality dream-bodies, dream-worlds and dream-pains have. In this paper I concentrate on Augustine's attempts to show that none of Victor's arguments for the corporeality of the soul are any good, and that Victor's inflated claims about the extent of the soul's self-knowledge are the result of mistaking self-awareness for self-knowledge. (...) Augustine takes the position that the feelings we have in dreams and the feelings of the dead, although they are real feelings, are not always the feelings they seem to be. This position is consistent with Augustine's later works, though it departs from his understanding of these issues in his earliest works. (shrink)

Jennifer Windt’s Dreaming is an enormously rich and thorough book, developing illuminating connections between dreaming, the methodology of psychology, and various philosophical subfields. I’ll focus on two epistemological threads that run through the book. The first has to do with the status of certain assumptions about dreams. Windt argues that the assumptions that dreams involve experiences, and that dream reports are reliable — are methodologically necessary default assumptions, akin to Wittgensteinian hinge propositions. I’ll suggest that Windt is quietly pre-supposing (...) some sceptical assumptions, and that recent literature in epistemic externalism may bear in important ways on her arguments. The second thread involves the perennial sceptical worry that dreaming threatens ordinary knowledge. I’ll suggest again that Windt makes tacit sceptical assumptions one may wish to resist. (shrink)

Aphantasia is a recently discovered disorder characterised by the total incapacity to generate visual forms of mental imagery. This paper proposes that aphantasia raises important theoretical concerns for the ongoing debate in the philosophy and science of consciousness over the nature of dreams. Recent studies of aphantasia and its neurobehavioral correlates reveal that the majority of aphantasics, whilst unable to produce visual imagery while awake, nevertheless retain the capacity to experience rich visual dreams. This finding constitutes a novel explanandum for (...) theories of dreaming. Specifically, I argue that the recent dream reports of aphantasics constitute an empirical challenge to the emerging family of views which claim that dreams are essentially imaginative experiences, constitutively involving the kinds of mental imagery which aphantasics, ex-hypothesi, lack. After presenting this challenge in the context of Jonathan Ichikawa’s recent arguments for this view, I argue that this empirical challenge may be overcome if the imagination theorist abandons Ichikawa’s account of dreaming in favour of a modified version. This involves the claim that dreams are essentially inactive and constitutively involve non voluntary forms of imagination. I conclude with a suggestion for further research which can test the viability of this alternative hypothesis, and move the debate forward. (shrink)

Dreaming is a communicative activity between the most sensitive archive of the enregistered experience of life on the earth, the brain, and the most plastic medium for the discovery and practice of meaning, the mind or culture. Both love and war have been made on the basis of dreams, not to mention scientific discoveries. In ancient Greece dreams were medicinal parts of curative sleeping or "incubation" rites in the temple of Aesculapius, and many psychoanalytic physicians today still consider dreams as (...) possessing therapeutic potential. The ethnographic literature gives ample testimony to the great significance accorded to dreams by all of the world cultures. Dreams form a rich store of ethnographic evidence, and their indigenous interpretations can often illuminate the central issues and conflicts of a people otherwise hidden from obvious view. Given these facts, plus the physiological facts that the dream process itself involves deeply-rooted material brain functions, and that rapid eye movement, or REM, sleep, which is the key indicator of human dreaming, is shared by all mammals, it remains strange how little attention is given to dreaming as a formative aspect of human evolution and culture. -/- This essay addresses dreaming as a formative aspect of human evolution and culture by viewing dreaming as a borderland between biology and culture, a thoroughly social, yet private experience. Dreaming not only highlights the "cultic" roots of culture—the spontaneous impulse to meaning—but also illustrates one of the ways in which the technics of the biosocial human body itself form the primary source of culture. I show why dreaming, although private, is a thoroughly cultural, biological, communicative activity. -/- Culture and biology are often treated by social scientists as though they were oil and water, not to be mixed. I should inform the culture theorist at the start that I am fully aware of the assumed nature-culture dichotomy, and that I reject it. I do so not because I am a sociobiologist, quite the contrary, rather because I am a semiotician, and my studies of signs have led me toward a critical reconstruction of the concepts of nature and culture. In what follows I beg the reader's patience, since I will draw from diverse materials and project some speculative hypotheses in places in order to make my argument. -/- . (shrink)

Higher-Order Thought (HOT) theories of consciousness maintain that the kind of awareness necessary for phenomenal consciousness depends on the cognitive accessibility that underlies reporting. -/- There is empirical evidence strongly suggesting that the cognitive accessibility that underlies the ability to report visual experiences depends on the activity of the dorsolateral prefrontal cortex (dlPFC). This area, however, is highly deactivated during the conscious experiences we have during sleep: dreams. HOT theories are jeopardized, as I will argue. I will briefly present HOT (...) theories in the first section. Section 2 offers empirical evidence to the effect that the cognitive accessibility that underlies the ability to report depends on the dorsolateral prefrontal cortex: dlPFC is the neural correlate of HOTs. Section 3 shows the evidence we have of the deactivation of this brain area during dreams and, in section 4, I present my argument. Finally, I consider and rejoin two possible replies that my opponent can offer: the possibility of an alternative neural correlate of HOTs during dreams and the denial that we have phenomenally conscious experiences during sleep.
