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)

How does consciousness vary across the animal kingdom? Are some animals ‘more conscious’ than others? This article presents a multidimensional framework for understanding interspecies variation in states of consciousness. The framework distinguishes five key dimensions of variation: perceptual richness, evaluative richness, integration at a time, integration across time, and self-consciousness. For each dimension, existing experiments that bear on it are reviewed and future experiments are suggested. By assessing a given species against each dimension, we can construct a (...) consciousness profile for that species. On this framework, there is no single scale along which species can be ranked as more or less conscious. Rather, each species has its own distinctive consciousness profile. (shrink)

Conscious states—state that there is something it is like to be in—seem both rich or full of detail and ineffable or hard to fully describe or recall. The problem of ineffability, in particular, is a longstanding issue in philosophy that partly motivates the explanatory gap: the belief that consciousness cannot be reduced to underlying physical processes. Here, we provide an information theoretic dynamical systems perspective on the richness and ineffability of consciousness. In our framework, the richness of conscious (...) experience corresponds to the amount of information in a conscious state and ineffability corresponds to the amount of information lost at different stages of processing. We describe how attractor dynamics in working memory would induce impoverished recollections of our original experiences, how the discrete symbolic nature of language is insufficient for describing the rich and high-dimensional structure of experiences, and how similarity in the cognitive function of two individuals relates to improved communicability of their experiences to each other. While our model may not settle all questions relating to the explanatory gap, it makes progress toward a fully physicalist explanation of the richness and ineffability of conscious experience—two important aspects that seem to be part of what makes qualitative character so puzzling.

This special issue is about something most of us might find very hard to conceive: states of consciousness in which self-consciousness is radically disrupted or altogether missing.

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)

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)

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)

Belief-state ascription — determining what someone “knew,” “believed,” was “aware of,” etc. — is central to many areas of law. In criminal law, the distinction between knowledge and recklessness, and the use of broad jury instructions concerning other belief states, presupposes a common and stable understanding of what those belief-state terms mean. But a wealth of empirical work at the intersection of philosophy and psychology — falling under the banner of “Experimental Epistemology” — reveals how laypeople’s understandings of mens rea (...) concepts differ systematically from what scholars, courts, and perhaps legislators, have assumed. -/- As implemented, mens rea concepts are much more context-dependent and normatively evaluative than the conventional wisdom suggests, even assuming that jurors are following jury instructions to the letter. As a result, there is less difference between knowledge and recklessness than is typically assumed; jurors consistently “over”-ascribe knowledge to criminal defendants; and concepts like “belief,” “awareness,” and “conscious disregard” mean different things in different contexts, resulting in mens rea findings systematically responsive to aspects of the case traditionally considered irrelevant to the meaning of those terms. -/- This Article provides the first systematic account of the factors driving jurors’ ascriptions of the specific belief states criminal law invokes. After surveying mens rea jury instructions, introducing the Experimental Epistemology literature to the legal literature on mens rea, and examining the implications of that literature for criminal law, this Article considers ways to begin bridging the surprisingly large gap between mens rea theory and practice.

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)

Since its proposition, the Knowledge Argument has been the center of debate in the Philosophy of the Mind, and many philosophers have proposed their rejections of it. This paper briefly looked at what Philip Goff characterized as the no-compromise response and the no propositional knowledge response before delving deep into a critique of Brian Loar's response to the Knowledge Argument. This paper accepts Brian Loar's critique of the semantic premise and his analysis of phenomenal concepts. However, after examining the implications (...) of Loar's response through conscious experience, this paper contends those implications conflict with simple intuitions and an analysis of the role of basic experiences in type-demonstrative referencing. It leads to new insights into the location of the dialectic of the Knowledge Argument being external to the brain. For the new dialectic of the Knowledge argument, I argue that a simpler Knowledge Argument provides an account of the referent of phenomenal concepts to be phenomenal properties (qualia), showing that Loar's response did not adequately reject the Knowledge Argument.

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)

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)

In this paper, I offer evidence that folk views of free will and moral responsibility accord a central place to consciousness. In sections 2 and 3, I contrast action production via conscious states and processes with action in concordance with an agent's long-standing and endorsed motivations, values, and character traits. Results indicate that conscious action production is considered much more important for free will than is concordance with motivations, values, and character traits. In section 4, I contrast the absence (...) of consciousness with the presence of consciousness in behaviorally identical agents. Most participants attribute free will to conscious agents, but not to nonconscious agents. Focusing in particular on two leading views of free will and moral responsibility, namely, Deep Self and Reasons-Responsive Views, I argue that these results present philosophers of mind and action with the following explanatory burden: develop a substantive theory of the connection between consciousness on the on..

Bayne and Carter argue that the mode of consciousness induced by psychedelic drugs does not fit squarely within the traditional account of modes as levels of consciousness, and favor instead a multi-dimensional account according to which modes of consciousness differ along several dimensions—none of which warrants a linear ordering of modes. We discuss the assumption that psychedelic drugs induce a single or paradigmatic mode of consciousness, as well as conceptual issues related to Bayne and Carter’s main (...) argument against the traditional account. Finally, we raise a set of questions about the individuation of dimensions selected to differentiate modes of consciousness that could be addressed in future discussions of the multi-dimensional account.

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.

Important conceptual and metaphysical issues arise when we try to understand the mental lives of “split-brain” subjects. How many distinct streams of consciousness do they have? According to Elizabeth Schechter’s partial unity model, the answer is one. A related question is whether co-consciouness, in general, is transitive. That is, if α and β are co-conscious experiences, and β and γ are co-conscious experiences, must α and γ be co-conscious? According to Schechter, the answer is no. The partial unity model (...) faces some serious objections. Its underpinnings are suspect, and ways of working out the model fall into trouble of various sorts: incoherence, emptiness, or unacceptable indeterminacy about the identity of (token) conscious states. One apparent lesson is that a subject can host two distinct conscious experiences of the same sort. Another is that the co-consciousness relation is transitive after all. (shrink)

In recent years, the scientific study of meditation and psychedelic drugs has seen remarkable developments. The increased focus on meditation in cognitive neuroscience has led to a cross-cultural classification of standard meditation styles validated by functional and structural neuroanatomical data. Meanwhile, the renaissance of psychedelic research has shed light on the neurophysiology of altered states of consciousness induced by classical psychedelics, such as psilocybin and LSD, whose effects are mainly mediated by agonism of serotonin receptors. Few attempts have been (...) made at bridging these two domains of inquiry, despite intriguing evidence of overlap between the phenomenology and neurophysiology of meditation practice and psychedelic states. In particular, many contemplative traditions explicitly aim at dissolving the sense of self by eliciting altered states of consciousness through meditation, while classical psychedelics are known to produce significant disruptions of self-consciousness, a phenomenon known as drug-induced ego dissolution. In this article, we discuss available evidence regarding convergences and differences between phenomenological and neurophysiological data on meditation practice and psychedelic drug-induced states, with a particular emphasis on alterations of self-experience. While both meditation and psychedelics may disrupt self-consciousness and underlying neural processes, we emphasize that neither meditation nor psychedelic states can be conceived as simple, uniform categories. Moreover, we suggest that there are important phenomenological differences even between conscious states described as experiences of self-loss. As a result, we propose that self-consciousness may be best construed as a multidimensional construct, and that “self-loss,” far from being an unequivocal phenomenon, can take several forms. Indeed, various aspects of self-consciousness, including narrative aspects linked to autobiographical memory, self-related thoughts and mental time travel, and embodied aspects rooted in multisensory processes, may be differently affected by psychedelics and meditation practices. Finally, we consider long-term outcomes of experiences of self-loss induced by meditation and psychedelics on individual traits and prosocial behavior. We call for caution regarding the problematic conflation of temporary states of self-loss with “selflessness” as a behavioral or social trait, although there is preliminary evidence that correlations between short-term experiences of self-loss and long-term trait alterations may exist.

A model of human consciousness is presented here in terms of physics and electronics using Upanishadic awareness. The form of Atman proposed in the Upanishads in relation to human consciousness as oscillating psychic energy-presence and its virtual or unreal energy reflection maya, responsible for mental energy and mental time-space are discussed. Analogy with Fresnel’s bi-prism experimental set up in physical optics is used to state, describe and understand the form, structure and function of Atman and maya, the ingredients (...) of human consciousness. A description of phases of mind in terms of conscious states and transformation of mental energy is given. Four states of consciousness and four modes of language communication and understanding processes are also given. Implications of above scientific awareness of Upanishadic wisdom to the modern scientific fields of physiological psychology, cognitive sciences, mind-machine modeling and natural language comprehension are suggested. -/- .

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)

Ever since the early days of quantum mechanics it has been suggested that consciousness could be linked to the collapse of the wave function. However, no detailed account of such an interplay is usually provided. In this paper we present an objective collapse model where the collapse operator depends on integrated information, which has been argued to measure consciousness. By doing so, we construct an empirically adequate scheme in which superpositions of conscious states are dynamically suppressed. Unlike other (...) proposals in which “consciousness causes the collapse of the wave function,” our model is fully consistent with a materialistic view of the world and does not require the postulation of entities suspicious of laying outside of the quantum realm.

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)

The stream of human consciousness appears to be interruptible, in that we can experience a sensation of ‘returning to ourselves after an absence of content’ (e.g. sleep, anaesthesia, full-absorption meditation). Prima facie, such evidence poses a challenge to simple applications of theories of consciousness based on electromagnetic or neural activity in the brain, because some of this activity persists during periods of interruption. This paper elaborates one of several possible responses to the challenge. We build on a previous (...) theory in which EM field topology delineates complex macrophenomenal experience. We first apply an analytic lens to identify different ways in which field topologies might generate sensations of ‘absence of content’. We then test the feasibility of a particular phenomenological approach for assessing those field topologies, powered by the unusual lucidity about cessation pathways induced via certain meditation practices and psychedelic dosages. We build computational simulations of these cessation pathways and test them on eight interviewees with various levels of experience in cessation states. We conclude that this approach can generate usable insight, but requires further formalisation to fulfil its potential. The findings tentatively support our claims but the theory remains speculative at this stage. We set out empirical tests with 11 specific predictions, both for further phenomenological research and for brain manipulation research. Although they align neatly, our ontological and cessation theories can also be separated. The paper describes how our theories can be consistent with other perspectives on consciousness, such as variants of predictive processing or global network theory. (shrink)

In the science of consciousness, it’s oftentimes assumed that some creatures (or mental states) are more conscious than others. But in recent years, a number of philosophers have argued that the notion of degrees of consciousness is conceptually confused. This paper (1) argues that the most prominent objections to degrees of consciousness are unsustainable, (2) examines the semantics of ‘more conscious than’ expressions, (3) develops an analysis of what it is for a degreed property to count as (...) degrees of consciousness, and (4) applies the analysis to various theories of consciousness. I argue that whether consciousness comes in degrees ultimately depends on which theory of consciousness turns out to be correct. But I also argue that most theories of consciousness entail that consciousness comes in degrees. (shrink)

This paper has three goals. The first is to introduce the “knowledge game”, a new, simple and yet powerful tool for analysing some intriguing philosophical questions. The second is to apply the knowledge game as an informative test to discriminate between conscious (human) and conscious-less agents (zombies and robots), depending on which version of the game they can win. And the third is to use a version of the knowledge game to provide an answer to Dretske’s question “how do you (...) know you are not a zombie?”. (shrink)

I introduce a novel multidimensional framework tailored to investigate a set of phenomena that might appear intractable and render them amenable to scientific inquiry. In particular, I focus on examining altered states of consciousness that appear to the experiencing subject as “contentless” or “objectless” states in some form, either by having disrupted or reduced content of awareness, or content that appears as missing altogether. By drawing on empirical research, I propose a cluster of phenomenological dimensions aimed at enhancing our (...) understanding of this group of experiences of minimal awareness, including “Richness of the Content”, “Bodily-Awareness”, “Passage of Time”, “Attentional Focus”, and “Self-Revelation”. The result is a robust framework that provides precise scientific terminology, facilitating its operationalisation and adaptability for future empirical work. I show the explanatory power of this framework through a case study of the state of clear light sleep—a state widely reported by Indo-Tibetan Buddhist traditions as an instance of pure awareness during sleep, a state of consciousness-as-such. This rare phenomenon has gained increasing attention in contemporary analytic philosophy of mind for the study of the nature of consciousness. However, we still lack consensus on its characterisation and potential identity with other associated states. I end the paper by illustrating how the state of clear light sleep can be situated in relation to other associated states and more ordinary ones as regions of a multidimensional state space.

It is often thought that consciousness has a qualitative dimension that cannot be tracked by science. Recently, however, some philosophers have argued that this worry stems not from an elusive feature of the mind, but from the special nature of the concepts used to describe conscious states. Marc Champagne draws on the neglected branch of philosophy of signs or semiotics to develop a new take on this strategy. The term “semiotics” was introduced by John Locke in the modern period (...) – its etymology is ancient Greek, and its theoretical underpinnings are medieval. Charles Sanders Peirce made major advances in semiotics, so he can act as a pipeline for these forgotten ideas. Most philosophers know Peirce as the founder of American pragmatism, but few know that he also coined the term “qualia,” which is meant to capture the intrinsic feel of an experience. Since pragmatic verification and qualia are now seen as conflicting commitments, Champagne endeavors to understand how Peirce could (or thought he could) have it both ways. The key, he suggests, is to understand how humans can insert distinctions between features that are always bound. Recent attempts to take qualities seriously have resulted in versions of panpsychism, but Champagne outlines a more plausible way to achieve this. So, while semiotics has until now been the least known branch of philosophy ending in –ics, his book shows how a better understanding of that branch can move one of the liveliest debates in philosophy forward.

According to the transparency thesis, some conscious states are transparent or “diaphanous”. This thesis is often believed to be incompatible with an inner‐awareness account of phenomenal consciousness. In this article, I reject this incompatibility. Instead, I defend a compatibilist approach to transparency. To date, most attempts to do so require a rejection of strong transparency in favor of weak transparency. In this view, transparent states can be attended to by attending (in the right way) to the presented world: that (...) is, they are merely translucent. Here, I first argue that this understanding of transparency is too weak to qualify as a compatibilist view. Drawing on insights from Franz Brentano, I then describe a middle road between strong and weak transparency. The crucial idea is that, although transparent states cannot be attended to, they can be noticed (under suitable conditions). This view, I submit, allows supporters of inner awareness to commit themselves to a more interesting understanding of transparency—moderate transparency—that preserves the initial intuition underlying the transparency metaphor.

Many philosophers and scientists have argued that the difference between phenomenally conscious states and other kind of states lies in the implicit self-awareness that conscious states have. Higher-Order Representationalist theories, attempt to explain such a self-awareness by means of a higher-order representation. Consciousness relies on our capacity to represent our own mental states, consciousness depends on our Theory of Mind. Such an ability can, at least conceptually, be decomposed into another two: mindreading and metacognition. In this paper I (...) will argue that consciousness cannot depend on mindreading. The tenability of HOR theories depends, therefore, on the relation between mindreading and metacognition. I analyze several views on such a relation and argue that none of them seem to be a plausible option for HOR theories. (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.

We generally accept that medicine’s conceptual and ethical foundations are grounded in recognition of personhood. With patients in vegetative state, however, we’ve understood that the ethical implications of phenomenal consciousness are distinct from those of personhood. This suggests a need to reconsider medicine’s foundations. What is the role for recognition of consciousness (rather than personhood) in grounding the moral value of medicine and the specific demands of clinical ethics? I suggest that, according to holism, the moral value of (...) medicine is secured when conscious states are recognized in everyday medical science. Moreover, consciousness fully motivates traditional principles of clinical ethics if we understand respect for autonomy as respect for the dominion of an experiencer in the private, inescapable realm of bodily experience. When medicine’s foundations are grounded in recognition of consciousness, we understand how patients fully command respect even when they lack capacity to exercise their bodily dominion through decision-making.

"Illusory Self Framework," a novel model integrating insights from predictive brain and contemplative practices. The framework proposes a hierarchical cognitive architecture grounded in the "all-ground," the foundational space of pure awareness. Within this architecture, neuronal packets, knowledge domains, and thoughtseeds interact, leading to an emergent self—a dynamic Markov blanket modulating conscious experience. This framework explores the dissolution of the illusory self through contemplative practices drawn from Indo-Tibetan traditions, the insights of J. Krishnamurti and recent research on minimal phenomenal experiences (MPEs) (...) and self-models. It posits that by modulating attention, reducing self-referential processing, and cultivating stillness, one can weaken the emergent self and reveal the underlying all-ground of pure awareness. An illustrative mathematical model formalizes these concepts, for emergence and the dissolving process of the illusory self. Furthermore, the framework elucidates the unfolding of MPEs by proposing a 5-stage lucidity pathway for advanced meditators. This pathway begins with lucid dreaming and culminates in an attentive sleepful state, highlighting the progressive dissolution of the illusory self and the deepening of non-dual awareness. The framework also offers testable predictions about the sleep architecture of advanced meditators using signal-validated lucidity tracking measures and how it might change with progression in these practices.

In “Radical Interpretation” (1974), David Lewis asked: by what constraints, and to what extent, do the non-intentional, physical facts about Karl determine the intentional facts about him? There are two popular approaches: the reductive externalist program and the phenomenal intentionality program. I argue against both approaches. Then I sketch an alternative multistage account incorporating ideas from both camps. If we start with Karl's conscious experiences, we can appeal to Lewisian ideas to explain his other intentional states. This account develops the (...) multistage Lewisian approach presented at the end of my earlier "Does Phenomenology Ground Mental Content?" (2013). (shrink)

When someone is in a conscious state, must they be aware of it? The Buddhist philosopher Dignāga offers a brilliant route to answering this question by leveraging the role awareness might play as a constraint on memory. I begin by clarifying his strategy and what conclusions it might be used to establish, and then turn to explain why it fails. The first main problem is that, contrary to his contemporary defenders, there is no good way to use it to reach (...) a conclusion about all conscious states. The second main problem is that the proposed awareness constraint on memory is highly problematic, in tension both with ancient objections as well as current psychology. (shrink)

The chief themes of this discussion are as follows. First, we need a theory of the grounds of moral status that could guide practical considerations regarding how to treat the wide range of potentially conscious entities with which we are acquainted – injured humans, cerebral organoids, chimeras, artificially intelligent machines, and non-human animals. I offer an account of phenomenal value that focuses on the structure and sophistication of phenomenally conscious states at a time and over time in the mental lives (...) of conscious subjects. Second, we need to map a theory of moral status onto practical considerations. I prefer the precautionary framework proposed by many, and fruitfully precisified recently by Birch. I have suggested that in addition to further discussion surrounding the evidential bar for attributing consciousness to different types of entities, more discussion is needed regarding how value and moral status may vary across different entity-types, and regarding the sources of value in an entity’s mental life.

We defend a functionalist approach to emotion that begins by focusing on emotions as central states with causal connections to behavior and to other cognitive states. The approach brackets the conscious experience of emotion, lists plausible features that emotions exhibit, and argues that alternative schemes are unpromising candidates. We conclude with the benefits of our approach: one can study emotions in animals; one can look in the brain for the implementation of specific features; and one ends up with an architecture (...) of the mind in which emotions are fully accommodated through their relations to the rest of cognition. Our article focuses on arguing for this general approach; as such, it is an essay in the philosophy of emotion rather than in the psychology or neuroscience of emotion. (shrink)

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)

In this paper we describe a few interrelated issues for validating theories that posit levels of consciousness. First, validating levels of consciousness requires consensus about the ordering of conscious states, which cannot be easily achieved. This problem is particularly severe if we believe conscious states can be irreducibly smeared over time. Second, the relationship between conscious states is probably sometimes intransitive, which means levels of consciousness will not be amenable to a single continuous measure. Finally, even if (...) a multidimensional approach to levels of consciousness is adopted, we argue that there are further problems for its validation. (shrink)

[This download contains the table of contents and Chapter 1]. I argue here that the claim that conscious states are private, in the sense that only one person can ever experience them directly, is false. There actually is a way to connect the brains of two people that would allow one to have direct experience of the other's conscious, e.g., perceptual states. This would allow, for instance, one person to see that the other had deviant color perception (which was masked (...) by correct linguistic practice). This could be achieved by connecting one person's set of executive processes (or cognitive control network) to the conscious perceptual states of the other. Chapter 5 contains an internalist physicalist account of color according to which colors exist only as brain states. Their function is to enable more precise causal interactions between the executive processes and the brain's perceptual systems. This in turn allows for more precise action: I can select the red apples and leave the green ones. (shrink)

Given the ever-present subject of consciousness wherever consciousness is, it is peculiar that consciousness researchers often mention mental states as if they are conscious independently of being the conscious states of someone [1, p. 132]. We refer to visual perceptions that become conscious, when in reality no one has ever studied mere conscious visual perceptions. What are studied are visual perceptions belonging to conscious human or animal subjects; it is the subjects who are conscious of visual stimuli, (...) not the visual perceptions. I do not know all the reasons why conscious subjects are rarely mentioned in consciousness science, but one could be pragmatic. Explaining the mysterious jump from the nonconscious nuts and bolts of neurons to the aurora borealis of consciousness is a hard problem. But it is an easy problem compared to explaining the emergence of a single conscious subject from the human brain’s 86 billion neurons [cf. 5]. Perhaps it is more practically realistic to solve the less hard problem before attempting to solve the harder hard problem. On the other hand, if we ignore a necessary condition for the presence of consciousness, our explanations of it could be plagued by inadequacy. And how can we explain our whole data set regarding consciousness if we neglect the most fundamental aspect of the data? (shrink)

Locke’s theory of personal identity was philosophically groundbreaking for its attempt to establish a non-substantial identity condition. Locke states, “For the same consciousness being preserv’d, whether in the same or different Substances, the personal Identity is preserv’d” (II.xxvii.13). Many have interpreted Locke to think that consciousness identifies a self both synchronically and diachronically by attributing thoughts and actions to a self. Thus, many have attributed to Locke either a memory theory or an appropriation theory of personal identity. But (...) the former stumble on circularity and the latter is insufficient for Locke’s moral theory insofar as he is committed to a theory of divine rectification. The common problem is that Locke’s theory seems to demand an objective, or metaphysical, fact of a continuing consciousness that does not appeal to a traditional notion of substance for the continuity. I’m suggesting something new. In II.xxvii of the Essay, we see an ambiguity in Locke’s use of the term ‘consciousness’. Locke seems to see consciousness as both a mental state by means of which we are aware of ourselves as perceiving and as the ongoing self we are aware of in these conscious states. First, I make the textual argument why we should read Locke as having a conception of a metaphysical fact of a continuing consciousness that does not appeal to thinking or bodily substance to establish its continuity. I then argue that the metaphysical fact of an enduring consciousness is revealed to us as a phenomenological fact of experience. Due to the nature of certain kinds of perceptual situations we have an experience of ourselves as temporally extended. Although the text bears out that Locke seemed to think there is a fact of an ongoing consciousness, I argue that it is consistent with his reluctance elsewhere that he makes no further epistemological or ontological claims about it. Finally, I provide an account of Locke’s understanding of memory and its relation to consciousness that supports the claim that consciousness is something ontologically distinct from either thinking or bodily substance.

There is good reason to think that, in every case of perceptual consciousness, there is something of which we are conscious; but there is also good reason to think that, in some cases of perceptual consciousness—for instance, hallucinations—there is nothing of which we are conscious. This paper resolves this inconsistency—which we call the presentation problem—by (a) arguing that ‘conscious of’ and related expressions function as intensional transitive verbs and (b) defending a particular semantic approach to such verbs, on (...) which they have readings that lack direct objects or themes. The paper further argues that this approach serves not only as a linguistic proposal about the semantics of ‘conscious of’, but also as a proposal about the metaphysics of conscious states. (shrink)

Control consciousness is the awareness or experience of seeming to be in control of one’s actions. One view, which I will be arguing against in the present paper, is that control consciousness is a form of sensory consciousness. In such a view, control consciousness is exhausted by sensory elements such as tactile and proprioceptive information. An opposing view, which I will be arguing for, is that sensory elements cannot be the whole story and must be supplemented (...) by direct contributions of nonsensory, motor elements. More specifically, I will be arguing for the view that the neural basis of control consciousness is constituted by states of recurrent activation in relatively intermediate levels of the motor hierarchy.

A widespread assumption in current philosophy of mind is that a conscious state’s phenomenal properties vary with its representational contents. In this paper, I present (rather dogmatically) an alternative picture that recognizes two kinds of phenomenal properties that do not vary concomitantly with content. First, it admits phenomenal properties that vary rather with attitude: what it is like for me to see rain is phenomenally different from what it is like for me to remember (indistinguishable) rain, which is different again (...) from what it is like for me to visualize (indistinguishable) rain – where these differences cannot be traced back to variations in content. Secondly, there is a kind of phenomenal property that varies neither with content nor with attitude but is altogether invariant across all conscious states: a substantive phenomenal commonality among what it is like for me to see, remember, and visualize rain, cats, or dogs. This substantive commonality, I will suggest, is the for-me-ness component of what it is like for me to have any of these experiences. I will close by discussing the interrelations among these three concentric layers of phenomenality: content-based, attitude-based, and for-me-ness. (shrink)

This paper explores the evolution of consciousness and subjectivity through a biological framework for understanding the universe. It posits that functional patterns in biological systems mirror cosmic mathematical principles, defining our objective reality. Similar to wave and Fibonacci patterns in different physical phenomena, biological patterns are intrinsic to all things and can be quantified using Dedre Gentner’s approach to analogy. For example, Earth’s ocean currents and the melting and freezing of Antarctica resemble the circulatory system and heart, while the (...) production of music from instruments is analogous to ribosomal protein synthesis. Shelves, tables, and chairs function like cytosol by holding objects in space, and a coffee cup mirrors red blood cell distribution. These analogies reveal a universal order rooted in biology’s functional patterns, essential for shaping the emergence and evolution of life. The paper traces the development of consciousness from its rudimentary cellular states to complex human cognition, highlighting the role of biologically-patterned environments in driving evolutionary changes. Organisms that recognized and organized according to these patterns evolved as “pattern recognition engines” crucial for survival—thus, Life (survival) being the primary measure of consciousness. Humans advanced this capacity, gaining cognitive freedom by insulating themselves from environmental constraints, but faced increased subjectivity complexity. Consciousness, while inherently subjective and necessary for cognitive development, evolves in humans to understand objective reality and its biological nature, so to understand and navigate complexities of subjectivity. Ultimately, the paper asserts consciousness is the ability to recognize and adhere to life-sustaining patterns and principles. Successful adherence deems them worthy of continued existence, while failure leads to demise. Parallels with historical concepts like Atman and Brahman in Hinduism suggest ancient recognition of the correspondence between human and universal patterns. This ancient understanding, coupled with modern scientific evidence, reveals the interconnectedness and intrinsic biological nature of reality. (shrink)

Starting from the paradigm of the material continuum we discuss the possibility to transcend the space-time reality (Here-and-Now) in the aim of investigating the energetic and informational reality, support of the continuous present. The altered states of consciousness, obtained by means of "psyche"-type techniques, allow the transformation of a future temporal nexus in an element of the present time. Through this "psyche anticipation" process, a sliding of the time reference takes place, since the future becomes present and the present (...) an element of the past. In this way the initial anticipatory potential is enhanced and allows one more energetic and informational step. By such a step-by-step progression segments of the future could be investigated, thus building an anticipatory model. The "psyche anticipation" techniques can be successfully used in the healing process of some diseases. (shrink)

How has multiplicity superseded impossibility in philosophical challenges to artificial consciousness? I assess a trajectory in recent debates on artificial consciousness, in which metaphysical and explanatory challenges to the possibility of building conscious machines lead to epistemological concerns about the multiplicity underlying ‘what it is like’ to be a conscious creature or be in a conscious state. First, I analyse earlier challenges which claim that phenomenal consciousness cannot arise, or cannot be built, in machines. These are based (...) on Block’s Chinese Nation and Chalmers’ Hard Problem. To defuse such challenges, theorists of artificial consciousness can appeal to empirical methods and models of explanation. Second, I explain why this naturalistic approach produces an epistemological puzzle on the role of biological properties in phenomenal consciousness. Neither behavioural tests nor theoretical inferences seem to settle whether our machines are conscious. Third, I evaluate whether the new challenge can be managed through a more fine-grained taxonomy of conscious states. This strategy is supported by the development of similar taxonomies for biological species and animal consciousness. Although it makes sense of some current models of artificial consciousness, it raises questions about their subjective and moral significance. (shrink)

Consciousness and emotion feature prominently in our personal lives, yet remain enigmatic. Recent advances prompt further distinctions that should provide more experimental traction: we argue that emotion consists of an emotion state (functional aspects, including emo- tional response) as well as feelings (the conscious experience of the emotion), and that consciousness consists of level (e.g. coma, vegetative state and wake- fulness) and content (what it is we are conscious of). Not only is consciousness important to aspects of (...) emotion but structures that are important for emotion, such as brainstem nuclei and midline cortices, overlap with structures that regulate the level of consciousness. The intersection of consciousness and emotion is ripe for experimental investigation, and we outline possible examples for future studies. (shrink)
