In a recent book, Neil Levy argues that culpable action – action for which we are morally responsible – is necessarily produced by states of which we are consciously aware. However, criminal defendants are routinely held responsible for criminal harm caused by states of which they are not conscious in Levy’s sense. In this chapter I argue that cases of negligent criminal harm indicate that Levy’s claim that moral responsibility requires synchronic conscious awareness of the moral significance of (...) an act is too strict, and that tracing conditions cannot be successfully used to bolster Levy’s account. Instead, current legal practices indicate that criminal responsibility requires the capacity for diachronic agency and self-control, not synchronic conscious control. (shrink)

For millennia self has been conjectured to be necessary for consciousness. But scant empirical evidence has been adduced to support this hypothesis. Inconsistent explications of “self” and failure to design apt experiments have impeded progress. Advocates of phenomenological psychiatry, however, have helped explicate “self,” and employed it to explain some psychopathological symptoms. In those studies, “self” is understood in a minimalist sense, sheer “for-me-ness.” Unfortunately, explication of the “minimal self” (MS) has relied on conceptual analysis, and applications to psychopathology have (...) been hermeneutic, allowing for many degrees of interpretive latitude. The result is that MS’s current scientific status is analogous to that of the “atom,” at the time when “atom” was just beginning to undergo transformation from a philosophical to a scientific concept. Fortunately, there is now an opportunity to promote a similar transformation for “MS.” Discovery of the brain’s Default Mode Network (DMN) opened the door to neuroimaging investigations of self. Taking the DMN and other forms of intrinsic activity as a starting point, an empirical foothold can be established, one that spurs experimental research and that enables extension of research into multiple phenomena. New experimental protocols that posit “MS” can help explain phenomena hitherto not thought to be related to self, thereby hastening development of a mature science of self. In particular, targeting phenomena wherein consciousness is lost and recovered, as in some cases of Unresponsive Wakefulness Syndrome (UWS), allow for design of neuroimaging probes that enable detection of MS during non-conscious states. These probes, as well as other experimental protocols applied to NREM Sleep, General Anesthesia (GA), and the waking state, provide some evidence to suggest that not only can self and consciousness dissociate, MS might be a necessary precondition for conscious experience. Finally, these findings have implications for the science of consciousness: it has been suggested that “levels of consciousness” (LoC) is not a legitimate concept for the science of consciousness. But because we have the conceptual and methodological tools with which to refine investigations of MS, we have the means to identify a possible foundation—a bifurcation point—for consciousness, as well as the means by which to measure degrees of distance from that foundation. These neuroimaging investigations of MS position us to better assess whether LoC has a role to play in a mature science of consciousness. (shrink)

Disorders of consciousness (DoC)—that is, unresponsive wakefulness syndrome/vegetative state and minimally conscious state—are debilitating conditions for which no reliable markers of consciousness recovery have yet been identified. Evidence points to the GABAergic system being altered in DoC, making it a potential target as such a marker.

Recent work in neuroimaging suggests that some patients diagnosed as being in the persistent vegetative state are actually conscious. In this paper, we critically examine this new evidence. We argue that though it remains open to alternative interpretations, it strongly suggests the presence of consciousness in some patients. However, we argue that its ethical significance is less than many people seem to think. There are several different kinds of consciousness, and though all kinds of consciousness have some ethical (...) significance, different kinds underwrite different kinds of moral value. Demonstrating that patients have phenomenal consciousness — conscious states with some kind of qualitative feel to them — shows that they are moral patients, whose welfare must be taken into consideration. But only if they are subjects of a sophisticated kind of access consciousness — where access consciousness entails global availability of information to cognitive systems — are they persons, in the technical sense of the word employed by philosophers. In this sense, being a person is having the full moral status of ordinary human beings. We call for further research which might settle whether patients who manifest signs of consciousness possess the sophisticated kind of access consciousness required for personhood. (shrink)

I offer a close reading of the first part of Sartre's The Transcendence of the Ego, arguing that contrary to widely held interpretation, one of Sartre's main goals in that text is to defend the view that consciousness does not necessitate self-awareness, that not all conscious states need be, ipso facto, states of self-awareness. In addition, I explain that this view about the conceptual relationship between consciousness and self-awareness has important methodological implications. One of the standard strategies for accounting (...) for the possibility of the type of capacity to have I* thoughts and attitudes is based on the assumption that being conscious necessarily entails being self-aware in at least a minimal sense, and then proceeds to explain how it I*-thoughts and attitudes are possible on the basis of those minimal states of self-awareness. Yet if Sartre's account of self-awareness is so much as plausible, this kind of strategy is bound to be incomplete. By helping itself to a notion of minimal self-awareness that is purportedly constitutive of consciousness, it fails to account for what is, by its own lights, the most fundamental form of self-awareness.

Laura Specker Sullivan (2022) makes a fairly compelling case for the value of the perspectives of Buddhist practitioners in neuroethics. In this study, Tibetan Buddhist monks have been asked, among other things, whether consciousness, in brain-injured patients in a minimally conscious state, entails a duty to preserve life. In our view, some of the participants’ responses could be used to inform the bioethical debate on death determination.

This paper argues that the many and various conceptions of consciousness propounded by cognitive scientists and philosophers can all be understood as constituted with reference to four fundamental sorts of criterion: epistemic (concerned with kinds of consciousness), semantic (dealing with orders of consciousness), physiological (reflecting states of consciousness), and pragmatic (seeking to capture types of consciousness). The resulting four-fold taxonomy, intended to be exhaustive, suggests that all of the distinct varieties of consciousness currently encountered in cognitive neuroscience, the philosophy of (...) mind, clinical psychology, and other related fields ultimately refer to a unified natural process, analysed under four general aspects. The proposed taxonomy will, it is hoped, possess sufficient clarity to serve as a sound theoretical framework for further scientific studies, and to count as a significant step in the direction of a properly formulated unified concept of consciousness.

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)

Disorders of consciousness include coma, the vegetative state and the minimally conscious state. Such patients are often regarded as unconscious. This has consequences for end of life decisions for these patients: it is much easier to justify withdrawing life support for unconscious than conscious patients. Recent brain imaging research has however suggested that some patients may in fact be conscious.

This chapter pursues the question of naturalism in the context of non-Western philosophical contributions to ethics and philosophy of mind: First, what conception of naturalism, if any, is best suited to capture the scope of Buddhist Reductionism? Second, can such a conception still accommodate the distinctive features of phenomenal consciousness (e.g., subjectivity, intentionality, first-person givenness, etc.). The first section reviews dominant conceptions of naturalism, and their applicability to the Buddhist project. In the second section, the author provides an example of (...) problematic issues more stringent conceptions of naturalism under the guise of neurophysicalism confront, and evaluate Flanagan’s response to these issues. The third section considers briefly the reflexivity thesis (the thesis that consciousness consists in conscious mental states being implicitly self-aware), specifically as articulated by Dignaga, Dharmakirti and their followers, and uses this thesis to articulate a conception of minimal agency as mineness that, the author argues, further challenges Flanagan’s neurophysicalism stance and his compatibilist account of moral agency. The paper concludes, in the fourth section, by suggesting a way in which no-ownership conceptions of reflexive self-consciousness can help us both to get the structure of phenomenal consciousness right and to ground our conceptions of agency, intentionality, and moral responsibility.

This article introduces and defends the “pathological complexity thesis” as a hypothesis about the evolutionary origins of minimal consciousness, or sentience, that connects the study of animal consciousness closely with work in behavioral ecology and evolutionary biology. I argue that consciousness is an adaptive solution to a design problem that led to the extinction of complex multicellular animal life following the Avalon explosion and that was subsequently solved during the Cambrian explosion. This is the economic trade-off problem of having to (...) deal with a complex body with high degrees of freedom, what I call “pathological complexity.” By modeling the explosion of this computational complexity using the resources of state-based behavioral and life history theory we will be able to provide an evolutionary bottom-up framework to make sense of subjective experience and its function in nature by paying close attention to the ecological lifestyles of different animals.

The claim that consciousness constitutively involves self-consciousness has a long philosophical history, and has received renewed support in recent years. My aim in this paper is to argue that this surprisingly enduring idea is misleading at best, and insufficiently supported at worst. I start by offering an elucidatory account of consciousness, and outlining a number of foundational claims that plausibly follow from it. I subsequently distinguish two notions of self-consciousness: consciousness of oneself and consciousness of one’s experience. While “self-consciousness” is (...) often taken to refer to the former notion, the most common variant of the constitutive claim, on which I focus here, targets the latter. This claim can be further interpreted in two ways: on a deflationary reading, it falls within the scope of foundational claims about consciousness, while on an inflationary reading, it points to determinate aspects of phenomenology that are not acknowledged by the foundational claims as being aspects of all conscious mental states. I argue that the deflationary reading of the constitutive claim is plausible, but should be formulated without using a term as polysemous and suggestive as “self-consciousness”; by contrast, the inflationary reading is not adequately supported, and ultimately rests on contentious intuitions about phenomenology. I conclude that we should abandon the idea that self-consciousness is constitutive of consciousness. (shrink)

Simona Ginsburg & Eva Jablonka (G&J), in _The Evolution of the Sensitive Soul (2019)_, explore the nature and status of the mind and subjective experiences from an evolutionary perspective. They raise a fundamental question about ‘the origin of animal consciousness during evolution’ (pg.1). The book begins by tracing the roots of consciousness studies from the Aristotelian perspective on the sensitive soul, referring to the dynamics of the living organization, percepts, and feelings. They use “subjective experiencing” to refer to both sentience (...) and consciousness. They argue that to have an evolutionary account of subjective experiences, we need to develop an understanding of minimal consciousness or a marker like unlimited associative learning (UAL) indicating subjective experiences. In the book, the origin of life is marked by the evolution of goal-directed systems where the system can manifest unlimited heredity. They state that all the questions about the origin of minimal consciousness deal with ‘the emergence of new types of goal-directed systems’ (p.1). (shrink)

There is little doubt that animals are ―conscious‖. Animals hunt prey, escape predators, explore new environments, eat, mate, learn, feel, and so forth. If one defines consciousness as being aware of external events and experiencing mental states such as sensations and emotions (Natsoulas, 1978), then gorillas, dogs, bears, horses, pigs, pheasants, cats, rabbits, snakes, magpies, wolves, elephants, and lions, to name a few creatures, clearly qualify. The contentious issue rather is: Do these animals know that they are perceiving an (...) external environment and experiencing internal events? Are animals self-conscious? Recent attempts at understanding animal consciousness (e.g., Edelman & Seth, 2009) agree that non-human animals most probably possess ―primary‖ (or ―minimal‖) consciousness. But these views also argue that unlike humans animals lack many (but not all) elements that make up higher-order consciousness—the capacity to self-reflect on the contents of primary consciousness. In this chapter I will aim at offering a more elaborate picture of this position. I will present detailed information on what is meant by ―higher-order consciousness‖—i.e., selfawareness. I will suggest that some dimensions of self-awareness (e.g., self-recognition, metacognition, mental time travel) may be observed in several animals, but that numerous additional aspects (e.g., self-rumination, emotion awareness) seem to be absent. Some other self-related processes, such as Theory-of Mind, have been identified in animals, but not as the full-fledged versions found in humans. I will postulate that these differences in levels of selfawareness between humans and animals may be attributable to one distinctive feature of human experience: the ability to engage in inner speech.

I argue that a version of Pascal's Wager applies to the persistent vegetative state with sufficient force that it ought to part of advance directives.

I consider the current best interests of patients who were once thought to be either completely unaware (to be in PVS) or only minimally aware (MCS), but who, because of advanced fMRI studies, we now suspect have much more “going on” inside their minds, despite no ability to communicate with the world. My goal in this chapter is twofold: (1) to set out and defend a framework that I think should always guide thinking about the best interests of highly (...) cognitively compromised patients, and then (2) to defend a particular conclusion that applies to this specific patient population. The framework requires us to ask two questions: Is the individual suffering? Is the individual gaining any benefit from life? There must be benefit of some sort for life to be worth preserving, and the benefit must outweigh any suffering (if there is suffering present). I then argue it would be best overall to allow these patients to die. Either these patients are not really very aware at all, in which case they are most likely not suffering, but not benefiting from life either, or they are mentally intact enough to make benefit a theoretical possibility, but in fact they are not benefiting because they cannot communicate with anyone. Such patients would most likely suffer. As there is no way currently to address their suffering, we should allow them to die. No matter the truth about their cognitive lives, death would either be a neutral event, or a blessing. (shrink)

How, if at all, consciousness can be part of the physical universe remains a baffling problem. This article outlines a new, developing philosophical theory of how it could do so, and offers a preliminary mathematical formulation of a physical grounding for key aspects of the theory. Because the philosophical side has radical elements, so does the physical-theory side. The philosophical side is radical, first, in proposing that the productivity or dynamism in the universe that many believe to be responsible for (...) its systematic regularities is actually itself a physical constituent of the universe, along with more familiar entities. Indeed, it proposes that instances of dynamism can themselves take part in physical interactions with other entities, this interaction then being “meta-dynamism” (a type of meta-causation). Secondly, the theory is radical, and unique, in arguing that consciousness is necessarily partly constituted of meta-dynamic auto-sensitivity, in other words it must react via meta-dynamism to its own dynamism, and also in conjecturing that some specific form of this sensitivity is sufficient for and indeed constitutive of consciousness. The article proposes a way for physical laws to be modified to accommodate meta-dynamism, via the radical step of including elements that explicitly refer to dynamism itself. Additionally, laws become, explicitly, temporally non-local in referring directly to quantity values holding at times prior to a given instant of application of the law. The approach therefore implicitly brings in considerations about what information determines states. Because of the temporal non-locality, and also because of the deep connections between dynamism and time-flow, the approach also implicitly connects to the topic of entropy insofar as this is related to time.

This essay seeks to acknowledge the unsettling reality of children being intentionally maimed towards disability and disfigurement as economic commodity. The issue is easily invisibilized in modern education, and understandably so: the trauma triggered by these bloody realities can automatically disqualify the content for formal in school education as a form of “unwelcome truth”. Freire and Fanon, however, did not shy away from the horrific state of life for the oppressed and the wretched in their consideration of pedagogy. The (...) lived experience of maimed children is tragic, but it is lived experience nonetheless – acknowledged by hooks as “a way of knowing that coexists in a non-hierarchical way with other ways of knowing” (2014). In other words, this knowledge exists but is arguably not mobilized by society towards action. Critical consciousness, upheld by Freire as the key to seeing inequality to act upon it, is a goal beyond reach for the maimed children themselves. Here, we consider the extension proposed by Nicholls (2011), who discusses pedagogy of the privileged as an equally important parallel towards collaborative action against long-standing inequalities. In the context of these children having minimal access to education, we contend that privileged students must be the ones to carry forth the knowledge towards their own critical consciousness. Specifically, we explore what acknowledging children who are maimed could offer towards pedagogy, in relation to helping students to 1) minimize the act of “othering” in a global community; 2) reconsider the role of mass-media and media literacy in their critical consciousness; and 3) move away from surface-level, performative charity against societal inequalities.

Realism about consciousness conjoins a claim that consciousness exists with a claim that the existence is independent in some interesting sense. Consciousness realism so conceived may thus be opposed by a variety of anti-realisms, distinguished from each other by denying the first, the second, or both of the realist’s defining claims. I argue that Dennett’s view of consciousness is best read as an anti-realism that affirms the existence of consciousness while denying an important independence claim.

The extended dual-aspect monism framework of consciousness, based on neuroscience, consists of five components: (1) dual-aspect primal entities; (2) neural-Darwinism: co-evolution and co-development of subjective experiences (SEs) and associated neural-nets from the mental aspect (that carries the SEs/proto-experiences (PEs) in superposed and unexpressed form) and the material aspect (mass, charge, spin and space-time) of fundamental entities (elementary particles), respectively and co-tuning via sensorimotor interaction; (3) matching and selection processes: interaction of two modes, namely, (a) the non-tilde mode that is the (...) material and mental aspect of cognition (memory and attention) related feedback signals in a neural-network, which is the cognitive nearest past approaching towards present; and (b) the tilde mode that is the material and mental aspect of the feed forward signals due to external environmental input and internal endogenous input, which is the nearest future approaching towards present and is a entropy-reversed representation of non-tilde mode; (4) the segregation and integration of information, and (5) the necessary ingredients of SEs (such as wakefulness, attention, re-entry, working memory, stimulus at or above threshold level, and neural-net PEs). This framework leads to structural and functional coherence between the mind and the brain, bridges the explanatory gap (the gap between SEs and their neural-correlates), and leads to our mundane subjective experiences. This extended dual-aspect monism (eDAM) framework (Vimal, 2008, 2010, 2013, 2015a, 2015b) could be the fundamental basis of various religions and philosophies. This is a Western perspective. On the other hand, Eastern perspectives emphasize the practical methods for achieving altered experience at samadhi state. An important corollary of these methods (such as yogic method) is the sublimation of negative aspects of seven groups of self-protective energy system (desire, anger, ego, greed, attachment, jealousy, and selfish-love) into their positive aspects. Their negative aspects create war and suffering, whereas their positive aspects advance science and technology, family values, peace, and happiness. Here, the Western perspective framework is extended to include the concepts of the sublimation process to encompass Eastern perspectives. The four elements (war, suffering, peace, and happiness) are ubiquitous in both space and time because they are essential contributors to the variations for natural selection in our evolutionary system. The sublimation process optimizes the system: minimizes war and suffering, maximizes peace and happiness, and enhances family values and individual progress. This is consistent with both Eastern and Western perspectives. (shrink)

A main goal of the neuroscience of consciousness is: find the neural correlate to conscious experiences (NCC). When have we achieved this goal? The answer depends on our operationalization of “NCC.” Chalmers (2000) shaped the widely accepted operationalization according to which an NCC is a neural system with a state which is minimally sufficient (but not necessary) for an experience. A deeper look at this operationalization reveals why it might be unsatisfactory: (i) it is not an operationalization (...) of a correlate for occurring experiences, but of the capacity to experience; (ii) it is unhelpful for certain cases which are used to motivate a search for neural correlates of consciousness; (iii) it does not mirror the usage of “NCC” by scientists who seek for unique correlates; (iv) it hardly allows for a form of comparative testing of hypotheses, namely experimenta crucis. Because of these problems (i–iv), we ought to amend or improve on Chalmers's operationalization. Here, I present an alternative which avoids these problems. This “NCC2.0” also retains some benefits of Chalmers's operationalization, namely being compatible with contributions from extended, embedded, enacted, or embodied accounts (4E-accounts) and allowing for the possibility of non-biological or artificial experiencers.

How can consciousness, how can the mind be causally efficacious in a world which seems—in some sense—to be thoroughly governed by physical causality? Mental causation has been a nagging problem in philosophy since the beginning of the modern age, when, inspired by the rise of physics, a metaphysical picture became dominant according to which the manifest macrophysical world of rocks, trees, colors, sounds etc. could be eliminated in favor of, or identified with, the microconstituents of these entities and their basic (...) physical properties, plus their effects on human or animal minds. Against the background of this ontology, the argument from causal closure, or the causal completeness of physics, exerts strong pressure to also identify consciousness with microphysical entities—or even to eliminate it in favor of the latter—the only other options apparently being either the denial of the causal closure of the physical level, epiphenomenalism about the mind, or the view that its physical effects are generally overdetermined. In this paper, however, I want to introduce what I call the “microstructure view” (MV) of the brain-consciousness relation, and I want to try to make plausible that the problem of mental causation can also be solved, or perhaps rather dissolved, on the basis of this account. On the MV, the minimal neuronal correlates of consciousness—of the global state of consciousness, or specific states of consciousness such as pain—are not identical with these states, but rather constitute their microstructure, or, as I shall also say, equivalently, compose them.

Mackenzie Graham has made an important contribution to the literature on decisionmaking for patients with disorders of consciousness. He argues, and I agree, that decisions for unresponsive patients who are known to retain some degree of covert awareness ought to focus on current interests, since such patients likely retain the kinds of mental capacities that in ordinary life command our current respect and attention. If he is right, then it is not appropriate to make decisions for such patients by appealing (...) to the values they had in the past, either the values expressed in an advance directive or the values recalled by a surrogate. There are two things I wish to add to the discussion. My first point is somewhat critical, for although I agree with his general conclusion about how, ideally, such decisions should be approached, I remain skeptical about whether his conclusion offers decisionmakers real practical help. The problem with these cases is that the evidence we have about the nature of the patient’s current interests is minimal or nonexistent. However—and this is important—Graham’s conclusion will be extremely relevant if in the future, our ability to communicate with such patients improves, as I hope it will. This leads to my second point. Graham’s conclusion illustrates a more general problem with our standard framework for decisionmaking for previously competent patients, a problem that has not been adequately recognized. So, in what follows, I explain the problem I see and offer some brief thoughts about solutions. (shrink)

This thesis investigates the relationship between consciousness and self-consciousness. I consider two broad claims about this relationship: a constitutive claim, according to which all conscious experiences constitutively involve self-consciousness; and a typicalist claim, according to which ordinary conscious experiences contingently involve self-consciousness. Both of these claims call for elucidation of the relevant notions of consciousness and self-consciousness. -/- In the first part of the thesis ('The Myth of Constitutive Self-Consciousness'), I critically examine the constitutive claim. I start by (...) offering an elucidatory account of consciousness, and outlining a number of foundational claims that plausibly follow from it. I subsequently distinguish between two concepts of self-consciousness: consciousness of one's experience, and consciousness of oneself (as oneself). Each of these concepts yields a distinct variant of the constitutive claim. In turn, each resulting variant of the constitutive claim can be interpreted in two ways: on a 'minimal' or deflationary reading, they fall within the scope of foundational claims about consciousness, while on a 'strong' or inflationary reading, they point to determinate aspects of phenomenology that are not acknowledged by the foundational claims as being aspects of all conscious mental states. I argue that the deflationary readings of either variant of the constitutive claim are plausible and illuminating, but would ideally be formulated without using a term as polysemous as 'self-consciousness'; by contrast, the inflationary readings of either variant are not adequately supported. -/- In the second part of the thesis ('Self-Consciousness in the Real World'), I focus on the second concept of self-consciousness, or consciousness of oneself as oneself. Drawing upon empirical evidence, I defend a pluralist account of self-consciousness so construed, according to which there are several ways in which one can be conscious of oneself as oneself – through conscious thoughts, bodily experiences and perceptual experiences – that make distinct determinate contributions to one's phenomenology. This pluralist account provides us with the resources to vindicate the typicalist claim according to which consciousness of oneself as oneself – a sense of self – is pervasive in ordinary conscious experiences, as a matter of contingent empirical fact. It also provides us with the resources to assess the possibility that a subject might be conscious without being conscious of herself as herself in any way. (shrink)

Explanation does not exist in a metaphysical vacuum. Conceptions of the structure of a phenomenon play an important role in guiding attempts to explain it, and erroneous conceptions of a phenomenon may direct investigation in misleading directions. I believe that there is a case to be made for thinking that much work on the neural underpinnings of consciousness—what is often called the neural correlates of consciousness—is driven by an erroneous conception of the structure of consciousness. The aim of this paper (...) is lay bare some connections between the explanation of consciousness and the structure of consciousness, and to argue for a conception of the structure of consciousness that is more adequate than that which currently drives much research into the neural correlates of consciousness.

One of the final obstacles to understanding consciousness in physical terms concerns the question of whether conscious states can exist in posterior regions of the brain without active connections to the brain's prefrontal lobes. If they can, difficult issues concerning our knowledge of our conscious states can be resolved. This paper contains a list of types of conscious states that may meet this criterion, including states of coma, states in which subjects are absorbed in a perceptual task, (...) states in brains with damaged prefrontal lobes, states of meditation and conscious states of some infants and animals. Recent evidence also suggests that conscious states of some people with autism may meet this criterion. (shrink)

This chapter explains how mindmelding — the direct experience by one person of another's conscious states — is in fact possible. The temporal lobes causally interact with the prefrontal lobes by way of fiber bundles that run underneath the cortical surface. This provides the perfect first experiment in mindmelding: to ‘branch’ those fiber bundles and run the other end into the brain of another person. Evidence is provided that these bundles have close connections to consciousness, in that whatever affects (...) them has immediate effects on consciousness. Then, before responding to several objections, the chapter considers another issue brought up by these experiments — the question of the relation between mindmelding and mindreading. Is mindmelding similar to mindreading? Does the existence of a mindreading system help us achieve mindmelding? (shrink)

Consciousness is known to be limited in processing capacity and often described in terms of a unique processing stream across a single dimension: time. In this paper, we discuss a purely temporal pattern code, functionally decoupled from spatial signals, for conscious state generation in the brain. Arguments in favour of such a code include Dehaene et al.'s long-distance reverberation postulate, Ramachandran's remapping hypothesis, evidence for a temporal coherence index and coincidence detectors, and Grossberg's Adaptive Resonance Theory. A time-bin (...) resonance model is developed, where temporal signatures of conscious states are generated on the basis of signal reverberation across large distances in highly plastic neural circuits. The temporal signatures are delivered by neural activity patterns which, beyond a certain statistical threshold, activate, maintain, and terminate a conscious brain state like a bar code would activate, maintain, or inactivate the electronic locks of a safe. Such temporal resonance would reflect a higher level of neural processing, independent from sensorial or perceptual brain mechanisms. (shrink)

Should models of consciousness be detailed _mechanistic_ models of particular types of systems, or should they be _minimal_ models that abstract away from the underlying mechanistic details and provide generalisations? Detailed mechanistic models may afford a complete and precise account of consciousness in human beings and other, physiologically similar mammals. But they do not provide a good model of consciousness in other animals, such as non-vertebrates, let alone artificial systems. Minimal models can be applicable to a wide range of different (...) conscious systems. But do they provide genuine explanations that are autonomous from explanations by detailed mechanistic models? This paper provides a taxonomy of minimal models and measures of consciousness, clarifies their relation to detailed mechanistic models, and highlights benefits of different minimalist approaches to consciousness.

The possibility of algorithmic consciousness depends on the assumption that conscious states can be copied or repeated by sufficiently duplicating their underlying physical states, leading to a variety of paradoxes, including the problems of duplication, teleportation, simulation, self-location, the Boltzmann brain, and Wigner’s Friend. In an effort to further elucidate the physical nature of consciousness, I challenge these assumptions by analyzing the implications of special relativity on evolutions of identical copies of a mental state, particularly the divergence of (...) these evolutions due to quantum fluctuations. By assuming the supervenience of a conscious state on some sufficient underlying physical state, I show that the existence of two or more instances, whether spacelike or timelike, of the same conscious state leads to a logical contradiction, ultimately refuting the assumption that a conscious state can be physically reset to an earlier state or duplicated by any physical means. Several explanatory hypotheses and implications are addressed, particularly the relationships between consciousness, locality, physical irreversibility, and quantum no-cloning. (shrink)

Some have argued that a subject has an inner awareness of its conscious mental states by virtue of the non-introspective, reflexive awareness that any conscious state has of itself. But, what exactly is it like to have a ubiquitous and reflexive inner awareness of one’s conscious states, as distinct from one’s outer awareness of the apparent world? This essay derives a model of ubiquitous inner awareness (UIA) from Sebastian Watzl’s recent theory of attention as the activity (...) of structuring consciousness into an experiential center and periphery. I develop Watzl’s theory into an account of UIA by suggesting that a subject is acquainted with its own conscious mental states through being reflexively aware of how these states are structured by attention into a unified subjective perspective. I favorably compare this Watzl-inspired account of UIA against other contemporary analytic and classical Buddhist accounts of reflexive awareness and subjective character, which variously ground the inner awareness of conscious states on their intrinsic phenomenal quality of “for-me-ness,” their affective/hedonic valence, or a subject’s disposition to introspect them. The Watzl-inspired account also accommodates possible counter-examples to Watzl’s theory posed by states of minimal phenomenal experience such as lucid dreamless sleep and non-dual meditative awareness.

According to Rosenthal's higher-order thought (HOT) theory of consciousness, one is in a conscious mental state if and only if one is aware of oneself as being in that state via a suitable HOT. Several critics have argued that the possibility of so-called targetless HOTs?that is, HOTs that represent one as being in a state that does not exist?undermines the theory. Recently, Wilberg (2010) has argued that HOT theory can offer a straightforward account of such cases: (...) since consciousness is a property of mental state tokens, and since there are no states to exhibit consciousness, one is not in conscious states in virtue of targetless HOTs. In this paper, I argue that Wilberg's account is problematic and that Rosenthal's version of HOT theory, according to which a suitable HOT is both necessary and sufficient for consciousness, is to be preferred to Wilberg's account. I then argue that Rosenthal's account can comfortably accommodate targetless HOTs because consciousness is best understood as a property of individuals, not a property of states. (shrink)

Commentary on: Olaf Blanke, Thomas Metzinger, Full-body illusions and minimal phenomenal selfhood, Trends in Cognitive Sciences, Volume 13, Issue 1, January 2009, Pages 7-13, ISSN 1364-6613, DOI: 10.1016/j.tics.2008.10.003.

I discuss here the nature of nonconscious mental states and the ways in which they may differ from their conscious counterparts. I first survey reasons to think that mental states can and often do occur without being conscious. Then, insofar as the nature of nonconscious mentality depends on how we understand the nature of consciousness, I review some of the major theories of consciousness and explore what restrictions they may place on the kinds of states that can occur (...) nonconsciously. I close with a discussion of what makes a state mental, if consciousness is not the mark of the mental. (shrink)

Consciousness in experimental subjects is typically inferred from reports and other forms of voluntary behaviour. A wealth of everyday experience confirms that healthy subjects do not ordinarily behave in these ways unless they are conscious. Investigation of consciousness in vegetative state patients has been based on the search for neural evidence that such broad functional capacities are preserved in some vegetative state patients. We call this the standard approach. To date, the results of the standard approach have (...) suggested that some vegetative state patients might indeed be conscious, although they fall short of being demonstrative. The fact that some vegetative state patients show evidence of consciousness according to the standard approach is remarkable, for the standard approach to consciousness is rather conservative, and leaves open the pressing question of how to ascertain whether patients who fail such tests are conscious or not. We argue for a cluster-based ‘natural kind’ methodology that is adequate to that task, both as a replacement for the approach that currently informs research into the presence or absence of consciousness in vegetative state patients and as a methodology for the science of consciousness more generally. 1.

The viewpoint that consciousness, including feeling, could be fully expressed by a computational device is known as strong artificial intelligence or strong AI. Here I offer a defense of strong AI based on machine-state functionalism at the quantum level, or quantum-state functionalism. I consider arguments against strong AI, then summarize some counterarguments I find compelling, including Torkel Franzén’s work which challenges Roger Penrose’s claim, based on Gödel incompleteness, that mathematicians have nonalgorithmic levels of “certainty.” Some consequences of strong (...) AI are then considered. A resolution is offered of some problems including John Searle’s Chinese Room problem and the problem of consciousness propagation under isomorphism. (shrink)

Working memory, an important posit in cognitive science, allows one to temporarily store and manipulate information in the service of ongoing tasks. Working memory has been traditionally classified as an explicit memory system – that is, as operating on and maintaining only consciously perceived information. Recently, however, several studies have questioned this assumption, purporting to provide evidence for unconscious working memory. In this paper, we focus on visual working memory and critically examine these studies as well as studies of unconscious (...) perception that seem to provide indirect evidence for unconscious working memory. Our analysis indicates that current evidence does not support an unconscious working memory store, though we offer independent reasons to think that working memory may operate on unconsciously perceived information.

The Origin of Consciousness Abstract The existence of human consciousness has received a great deal of attention within the scientific community. There are some who deny its existence altogether. There are those who believe it is nothing more than the result of physical properties within the brain. And there are some who contend it exists separate and apart from the brain. Many of these theories have been shaped by the desire of evolutionists to explain human consciousness via a purely materialistic/mechanistic (...) bent. In this paper, we provide a historical background to the conflict and examine the two broad categories—monism and dualism—that are used in an attempt to explain human consciousness. We also discuss many of their subcategories, to see how each fare in light of the available facts. Increasingly, experimental data document the fact that human consciousness is separate and distinct from the mere physical matter of the brain. This understanding indicates that there is, then, a non-material aspect of human beings that must be accounted for. (shrink)

Experimental philosophy of consciousness aims to investigate and explain our thinking about phenomenally conscious states. Based on empirical studies, researchers have argued (a) that we lack a folk concept of consciousness, (b) that we do not think entities like Microsoft feel regret, (c) that unfelt pains are widely accepted, and (d) that people do not attribute phenomenally conscious states to duplicated hamsters. In this article, I review these and other intriguing claims about people’s understanding of phenomenal consciousness. In (...) doing so, I also show why experimental philosophy of consciousness is challenging, although perhaps not quite as daunting as studying phenomenal consciousness itself. (shrink)

This article reconstructs Sartre’s theory of selfhood against the background of the contemporary debate between minimal-self theories and narrative-self theories. I argue that Sartre’s theory incorporates both an emphasis on the singular first-person perspective, which is characteristic of minimal-self theories, and an emphasis on the practical intelligibility of experience, which is characteristic of narrative-self theories. The distinctiveness of the Sartrean combination of these motifs consists in its idea of the necessary ideal-relatedness of consciousness. According to Sartre, the logical structure of (...) the pre-reflective cogito requires the haunting presence of an ideal of self-coincidence, which determines for consciousness the meaning of its lived experiences. Consciousness exists as a question to itself due to this ideal-relatedness, and it answers this question by projecting its possibilities as creative and symbolic realizations of this ideal. Establishing the connection between Sartre’s theory of imagination and his theory of selfhood, I suggest that both the ideal and the possibility of consciousness are lived in the manner of the imaginary.

An important distinction lies between consciousness attributed to creatures, or subjects, (creature consciousness) and consciousness attributed to mental states (state consciousness). Most contemporary theories of consciousness aim at explaining what makes a mental state conscious, paying scant attention to the problem of creature consciousness. This attitude relies on a deeper, and generally overlooked, assumption that once an explanation of state consciousness is provided, one has also explained all the relevant features of creature consciousness. I call this (...) the priority of state consciousness thesis (PSC). In this paper, I want to explore how the renewed centrality bestowed to phenomenology in contemporary discussions on consciousness challenges PSC and, consequently, the standard way of framing the problem of consciousness. More precisely, I examine PSC in light of a view about the structure of phenomenal character that is paradigmatic of the approach above. This is subjectivism about phenomenal character (SUBJ), according to which a mental state is conscious when it acquires the property of for-me-ness. I argue that PSC and SUBJ are incompatible because the latter implies that creature consciousness is explanatorily prior to state consciousness. Consequently, if SUBJ is true, then PSC is false, and what constitutes the problem of consciousness is primarily a problem of explaining (a kind of) creature consciousness. I conclude by defending my claim from a pair of possible objections and drawing some implications for the discussion of for-me-ness and the debate on the explanation of consciousness. (shrink)

Some of my mental states are conscious and some of them are not. Sometimes I am so focused on the wine in front of me that I am unaware that I am thinking about it; but sometimes, of course, I take a reflexive step back and become aware of my thinking about the wine in front of me. What marks the difference between a conscious mental state and an unconscious one? In this paper, I focus on Durand (...) of St.-Pourçain’s rejection of the higher-order theory of state consciousness, according to which a mental act is conscious when there is another, suitably related, mental (reflex) act that exists at the same time with it. Durand rejects such higher-order theories on the grounds that they violate the thesis that a given mental power can have or elicit only one mental act at a given time. I first go over some of Durand’s general arguments for this thesis. I then turn to Durand’s application of the thesis to the issue of state consciousnes and reflex acts. I close by considering the objection that Durand’s same-order theory of state consciousness makes consciousness ubiquitous. (shrink)

The nature of human mind has been an open question for more than 2000 years and it is still today a mystery. There has been during the last 30 years a renewed interest from science and philosophy on that subject. Among the existing research domains is neurophilosophy, an interdisciplinary study of neuroscience and philosophy looking at neuronal aspects of access consciousness, of phenomenal consciousness and at functional aspects of consciousness. We propose here to look if self-consciousness could have a place (...) in neurophilosophy by using an existing evolutionary scenario that can introduce possible links between neural processing and some aspects of self-consciousness. The scenario is about an evolutionary nature of self-consciousness where evolutions of inter-subjectivity and meaningful representations may have led our ancestors to identify with their conspecifics. The scenario proposes that this process has brought our pre-human ancestors to represent themselves as existing entities like the conspecifics they identified with were represented. Such a representation of oneself as an existing entity may have created an elementary version of self-consciousness that we name “ancestral self-consciousness”. But identification with suffering or endangered conspecifics has also produced an important anxiety increase. To limit that anxiety our ancestors have developed mental states and behaviors like caring, imitation communication and simulation. These performances have introduced evolutionary advantages leading to an evolutionary engine that has favored the development of ancestral self-consciousness toward our human self-consciousness. We begin by presenting a model for the generation of meaningful information based on a system submitted to an internal constraint (the Meaning Generator System). We use that model to introduce meaningful representations as networks of meaningful information. We then present the evolutionary scenario for self-consciousness that uses meaningful representations and the performance of inter-subjectivity. The scenario leads to propose two links between self-consciousness and neural processes: mirror-neurons as neural introduction to inter-subjectivity and self-consciousness as neural computation on meaningful representations. Possible continuations are highlighted. (shrink)

In a recent paper, Eric Schwitzgebel argues that if materialism about consciousness is true, then the United States is likely to have its own stream of phenomenal consciousness, distinct from the streams of conscious experience of the people who compose it. Indeed, most plausible forms of materialism have to grant that a certain degree of functional and behavioral complexity constitutes a sufficient condition for the ascription of phenomenal consciousness – and Schwitzgebel makes a case to show that the United (...) States as a whole fulfills this condition. One way to avoid this counter-intuitive consequence of materialism about consciousness is to adopt what Schwitzgebel calls an “anti-nesting principle”: a principle that states that there can be no nested forms of phenomenal consciousness and that therefore a conscious whole cannot have parts that are themselves conscious. However, Schwitzgebel then proceeds in his paper to draw up various objections, notably based on thought experiments, in order to dismiss these kinds of “anti-nesting” principles. My aim in this paper is to present a version of a sophisticated anti-nesting principle that avoids Schwitzgebel’s objections. This principle is reasonable, intuitive, and as non-arbitrary as possible. Moreover, it can resist the objections mounted by Schwitzgebel against simple anti-nesting principles. This principle helps materialists avoid the implication that the United States has its own stream of consciousness, while granting consciousness to some entities which, in many cases, are intuitive instantiators of phenomenal consciousness. This principle therefore constitutes a way out for a materialist who wants to deny that the United States is conscious. (shrink)

Conscious intentional states are mental states that represent things as being a certain way and do so consciously: they involve a phenomenally conscious representation. For any phenomenally conscious state, there is something it is like for its subject to be in it. The way it is like for a subject to be in a certain phenomenal state is the state’s phenomenal character. According to some authors, phenomenal character has two components: qualitative character (i.e., the (...) “what it is like” component) and subjective character (the “for the subject” component). Elsewhere, I have argued for an acquaintance theory of subjective character: a conscious representation is “for the subject” iff the subject is acquainted with it (Giustina forthcoming). The aim of this paper is to take some initial steps toward developing an acquaintance account of qualitative character. More specifically, I develop an acquaintance-representational account of the qualitative character of conscious intentional states, on which qualitative character is constituted by a subject’s being acquainted with the conscious intentional state’s representational properties. By reviewing the main extant accounts of qualitative character and highlighting their shortcomings, I argue that the acquaintance-representational account is antecedently more plausible than its competitors.

As soon as you believe an imagination to be nonfictional, this imagination becomes your ontological theory of the reality. Your ontological theory (of the reality) can describe a system as the reality. However, actually this system is only a theory/conceptual-space/imagination/visual-imagery of yours, not the actual reality (i.e., the thing-in-itself). An ontological theory (of the reality) actually only describes your (subjective/mental) imagination/visual-imagery/conceptual-space. An ontological theory of the reality, is being described as a situation model (SM). There is no way to prove/disprove (...) that there is only one reality, or there are two realities (i.e., “subjective reality” and “objective reality”). So, every ontology talk/theory/imagination about the two realities is only a talk/theory/imagination – we will never know whether it is true or not. The conventionally-called “physical/objective reality/world” around my conventionally-called “physical/objective body” is actually a geometric mathematical model (being generated/mathematically-modeled by my brain) – it's actually a subset/component/part/element of my brain’s mind/consciousness/manifest-image. Our cosmos is an autonomous objective parallel computing automaton (aka state machine) which evolves by itself automatically/unintentionally – wave-particle duality and Heisenberg’s uncertainty principle can be explained under this SM of my brain. Each elementary particle (as a building block of our cosmos) is an autonomous mathematical entity itself (i.e., a thing in itself). Our cosmos has the same nature as a Game of Life system – both are autonomous objective parallel-computing automata. Cosmos (as a state machine) is indistinguishable from a digital simulation – my consciousness (as something nonphysical) is not cosmos (as a state machine). If we are happy to accept randomness/stochasticity, then it is obviously possible that all other worlds in the many-worlds interpretation (MWI) actually do not exist (objectively). As one metaphysical option, we can treat all other worlds as subjective only (even if they are actually objective). Under the context of this metaphysical option, we are only living in one world (i.e., the world we are currently living in; this world) – we are not living in many worlds at the same time parallelly. Under the context of this metaphysical option, there is only one possible future. The relationship among any number of elementary particles, is governed/described by Schrodinger equation. If (in theory) Schrodinger equation can’t be used to reliably forecast whether I will go to McDonald for dinner in this world (based on the current state of all elementary particles of the cosmos), then what can Schrodinger equation do? The conventionally-called “space” does not exist objectively. “Time” and “matter” are not physical. Consciousness is the subjective-form (aka quale) of the mathematical models (of the objective cosmos) which are intracorporeally/subjectively used by the control logic of a Turing machine’s program fatedly. A Turing machine’s mind/consciousness/manifest-image or deliberate decisions/choices should not be able to actually/objectively change/control/drive the (autonomous or fated) worldline of any elementary particle within this world (i.e., the world we are currently living in, under the context of MWI). Besides the Schrodinger equation (or another mathematical equation/function which is yet to be discovered) which is a valid/correct/factual causality of our cosmos/state-machine, every other causality (of our cosmos/state-machine) is either invalid/incorrect/counterfactual or can be proved by deductive inference based on the Schrodinger equation (or the aforementioned yet-to-be-discovered mathematical equation/function) only. Closed causality entails no causality. Consciousness plays no causal role (“epiphenomenalism”), or in other words, any cognitive/behavioural activity can in principle be carried out without consciousness (“conscious inessentialism”). If the “loop quantum gravity” theory is correct, then time/space does not actually/objectively exist in the objective-evolution of the objective cosmos, or in other words, we should not use the subjective/mental concept of “time”, “state” or “space” to describe/imagine the objective-evolution of our cosmos.
