I am aware of the tree and its leaves, but am I aware of my awareness of these things? When I try to introspect my awareness, I just find myself attending to objects and their properties. This observation is known as the ‘transparency of experience’. On the other hand, I seem to directly know that I am aware. Given the first observation, it is not clear how I know that I am aware. Fred Dretske thought that the problem was so (...) acute that he issued the challenge of answering ‘How do you know that you are not a zombie?’ I propose that a view found in the Advaita Vedanta, that awareness is self luminous, reconciles these two observations. I understand self-luminosity as the thesis that: (1) I am implicitly aware of my awareness and (2) I am phenomenally aware of a distinct phenomenal character of my awareness. In support of the first claim, that I apparently only attend to objects in the world when introspecting perceptual experience, suggests that I do not know my awareness explicitly, but rather that I must know it implicitly. In support of the second claim, I argue that the mere fact that I am perceptually conscious is not sufficient to allow me to know that I am perceptually conscious. In particular, the qualities I am perceptually aware of do not tell me that I aware of them, rather they just seem to be properties of objects. I also assess whether strategies for responding to Cartesian sceptical scenarios can be employed against Dretske’s consciousness scepticism. I argue that these strategies either fail to distinguish me from a zombie or they do not adequately describe my epistemic situation. By contrast to other accounts, if awareness has its own distinct phenomenal character, then it cannot be considered to be a prima facie property of the world, hence the self-luminosity of awareness provides a plausible account of how I know that I’m not a zombie.

Our pains can be more or less intense, our mental imagery can be more or less vivid, our perceptual experiences can be more or less striking. These degrees of intensity of conscious experiences are all manifestations of a phenomenal property I call mental strength. In this article, I argue that mental strength is a domain-general phenomenal magnitude; in other words, it is a phenomenal quantity shared by all conscious experiences that explains their degree of felt intensity. Mental strength has been (...) largely overlooked in favor of mental states’ type, representational contents, domain-specific phenomenology, or processes such as attention. Considering mental strength in our reflections about the mind illuminates debates about the relation of representational contents and phenomenal character, and it also helps address questions about the structure and functions of consciousness. Mental strength provides a unifying construct to model what is shared in the phenomenology of different types of conscious experiences. (shrink)

Experiences of urges, impulses, or inclinations are among the most basic elements in the practical life of conscious agents. This article develops a theory of urges and their epistemology. The article motivates a tripartite framework that distinguishes urges, conscious experiences of urges, and exercises of capacities that agents have to control their urges. The article elaborates the elements of the tripartite framework, in particular, the phenomenological contribution of motor imagery. It argues that experiences of urges and exercises of control over (...) urges play coordinate roles in enabling an agent’s awareness of their impulses. (shrink)

I develop and defend "metaethical experientialism," the thesis that phenomenal facts explain certain kinds of value facts. I argue, for example, that anyone who knows what it’s like to feel extreme pain is in a position to know that that kind of experience is bad.

I also discuss the prospects for a pluralistic metaethics, whereby different metaethical theories hold (...) for different classes of ethical facts. (shrink)

The possibility of consciousness in human brain organoids is sometimes viewed as determinative in terms of the moral status such entities possess, and, in turn, in terms of the research protections such entities are due. This commonsense view aligns with a prominent stance in neurology and neuroscience that consciousness admits of degrees. My paper outlines these views and provides an argument for why this picture of correlating degrees of consciousness with moral status and research protections is mistaken. I then provide (...) an alternative account of the correlation between moral status and consciousness, and consider the epistemic ramifications for research protections of this account. (shrink)

The question of whether blindsight is a form of unconscious perception continues to spark fierce debate in philosophy and psychology. One side of the debate holds that while the visual information categorized in blindsight is not access-conscious, it is nonetheless a form of perception, albeit a form of unconscious perception. The opposition, by contrast, holds that blindsight is just a form of degraded conscious perception that makes the categorized information harder to access because it is degraded. In this chapter, we (...) address the opposition’s arguments for thinking that blindsight is a form of degraded conscious vision and then argue that the residual awareness found in blindsight is a form of non-perceptual awareness. To back this claim, we examine the residual visual abilities to detect and discriminate colour found in some blindsight patients and show that residual consciousness in blindsight is indirect and lacks the phenomenal character characteristic of conscious vision.

According to a common view, conscious thoughts necessarily involve quasi-perceptual experiences, or mental images. This is alleged to be the case not only when one entertains conscious thoughts about perceptible things, but also when one thinks about more abstract things. In the case of conscious abstract propositional thoughts, the idea is that they occur in inner speech, which is taken to involve imagery (typically auditory) of words in a natural language. I argue that unsymbolized thinking and total aphantasia cast doubt (...) on this common view. Unsymbolized thinking is the experience of thoughts that does not involve imagery. Total aphantasia is the inability to produce mental images of all sensory modalities. I consider and reject the objection that these individuals are mistaken either because their thoughts do involve images, or because those thoughts are not conscious. Thus, unsymbolized thinking and aphantasia provide evidence that conscious thoughts can occur without imagery. (shrink)

The scientific investigation of consciousness generates new findings at a rapid pace. We argue that we need a novel theoretical framework, which we call the ALARM theory of consciousness, in order to account for all central observations. According to this theory, we need to distinguish two levels of consciousness, namely basic arousal and general alertness. Basic arousal functions as a specific alarm system, keeping a biological organism alive under sudden intense threats, and general alertness enables flexible learning and behavioural strategies. (...) This two-level theory of consciousness helps us to account for (i) recent discoveries of subcortical brain activities with a central role of thalamic processes, (ii) observations of differences in the behavioural repertoire of non-human animals indicating two types of conscious experiences. Furthermore, the framework enables us (iii) to unify the neural evidence for the relevance of subcortical processes, on the one hand, and of cortico-cortical loops, on the other, and finally (iv) to clarify the evolutionary and actual functional role of conscious experiences.

The use of brain technology that contributes to psychological changes has spurred a debate about personal identity. Some argue that neurotechnology does not undermine personal continuity (Levy, 2011) while others argue that it does (Kreitmair, 2019; Schechtman, 2010). To make these assessments, commentators fail to identify psychological changes that cause personal discontinuity. In this paper, I present a view that identifies personal continuity with the maintenance of a self-concept. I argue that a concept of self requires the ability to self-ascribe (...) physical and psychological features and that the diachronic self emerges with self-ascriptions of features that require endurance over time. I maintain that an adequate concept of self does not depend on the maintenance of any particular combination of self-ascriptions and that it can be maintained despite even significant changes in psychological or physical traits. Finally, I apply the self-concept view to identify changes that can result in discontinuity of self. (shrink)

Higher-order thought (HOT) theory says that a mental state is conscious when and only when represented by a conceptual, belief-like mental state. Plausibly, HOT theory predicts the impairment of HOT-producing brain areas to cause significant deficits in consciousness. This means that HOT theory can be refuted by identifying those brain areas that are candidates for producing HOTs, then showing that damage to these areas never produces the expected deficits of consciousness. Building this refutation is a work-in-progress, with several key components (...) of it already existing in the literature (e.g., Boly et al. in J Neurosci 37(40):9603–9613, 2017; Kozuch in Mind Lang, 37(5):790–813, 2022). This article pulls together and supplements these earlier components so as to provide a comprehensive lesion-based argument against HOT theory, one which offers extra data and arguments in support of it, and which also addresses common objections.

The science of animal consciousness investigates (i) which animal species are conscious (the distribution question) and (ii) how conscious experience differs in detail between species (the quality question). We propose a framework which clearly distinguishes both questions and tackles both of them. This two-tier account distinguishes consciousness along ten dimensions and suggests cognitive capacities which serve as distinct operationalizations for each dimension. The two-tier account achieves three valuable aims: First, it separates strong and weak indicators of the presence of consciousness. (...) Second, these indicators include not only different specific contents but also differences in the way particular contents are processed (by processes of learning, reasoning or abstraction). Third, evidence of consciousness from each dimension can be combined to derive the distinctive multi-dimensional consciousness profile of various species. Thus, the two-tier account shows how the kind of conscious experience of different species can be systematically compared. (shrink)

When do companies deserve moral credit for doing what is right? This question concerns the positive side of corporate moral responsibility, the negative side of which is the more commonly discussed issue of when companies are blameworthy for doing what is wrong. I offer a broadly functionalist account of how companies can act from morally creditworthy motives, which defuses the following Strawsonian challenge to the claim that they can: morally creditworthy motivation involves being guided by attitudes of “goodwill” for others, (...) and these attitudes involve affect and/or phenomenal consciousness, which corporate agents cannot maintain. In response, I show that what matters about being guided by attitudes of goodwill is being directly concerned for others in one’s practical deliberation. Companies can achieve this direct concern through their decision-making procedures without affect or phenomenal consciousness. I also explore how a company’s moral creditworthiness, or lack thereof, should shape stakeholders’ relationship with it. (shrink)

Le présent essai tente de tirer au clair les différentes significations des termes « conscient » et « conscience » dans la philosophie critique de Kant et en particulier dans la Critique de la raison pure. On considère d’abord les divers types de représentations et ce que veut dire Kant lorsqu’il les dit « avec » ou « sans » conscience. On considère ensuite le concept de conscience tel qu’il apparaît dans la Déduction transcendantale des catégories, où il ne réfère (...) pas à une qualité de représentations particulières, mais à une attitude active de l’esprit. Considérée dans son ensemble, la conception kantienne de la « conscience » mêle inséparablement un aspect que nous appelons, après T. Nagel, « conscience phénoménale », et un aspect proche de la « conscience d’accès » selon N. Block, dans lequel cependant la conscience de soi, exprimable par la proposition « Je pense », joue un rôle central. Cette combinaison fait de Kant un interlocuteur unique dans les débats contemporains sur la conscience et son rôle dans notre vie mentale, ainsi que sur l’IA et sa signification pour l’avenir de l’humanité.

Proponents of the higher‐order (HO) theory of consciousness (e.g., Lau and Rosenthal) have recently appealed to brain lesion evidence to support their thesis that mental states are conscious when and only when represented by other mental states. This article argues that this evidence fails to support HO theory, doing this by first determining what kinds of conscious deficit should result when HO state‐producing areas are damaged, then arguing that these kinds of deficit do not occur in the studies to which (...) HO theorists appeal. The article also develops an apparatus that can be used to evaluate whether other lesion evidence confirms or disconfirms HO theory. (shrink)

This paper investigates the nature of emotional experience in relation to the senses, and it defends the thesis that emotional experience is partly non-sensory. In §1 I introduce my reader to the debate. I reconstruct a position I call ‘restrictivism’ and motivate it as part of a reductive approach to mind’s place in nature. Drawing on intuitive but insightful remarks on the nature of sensation from Plato, I map out the conditions under which the restrictivist thesis is both substantive and (...) plausible. I then present two arguments against it. The first argument, which I lay out in §2, draws on recent empirical results in emotion research to show that restrictivism cannot be reconciled with the possibility of knowledge of one’s own emotional state by acquaintance. The second argument, which I present in §3, individuates a claim on which most contemporary theories of emotional valence converge and uses it to demonstrate that restrictivism has a false implication: it must deny that valence is experientially felt.

The definition of death as “irreversible coma” was introduced in 1968 by the Harvard University Medical School. It was developed largely in diagnostic terms as the “irreversible cessation of all functions of the entire brain, including the brainstem.” In its review of brain death in 1981, The President’s Commission for the Study of Ethical Problems in Medicine argued that brain death is consonant with circulatory death because the loss of certain brain functions results in the “loss of integrative unity of (...) the organism,” leading to cardiac arrest. This picture of a unified conception of death was challenged by subsequent clinical evidence suggesting that, with proper treatment, circulatory death is not the inevitable result of brain death. Here, it is argued that, if death, in the morally relevant sense, is defined as irreversible loss of consciousness, a unitary conception of death can be maintained. However, significant theoretical and methodological obstacles remain in diagnosing irreversible loss of consciousness. (shrink)

The claim that phenomenal consciousness essentially involves self-consciousness, in the sense of _mineness_, has gained momentum in recent years. In this paper, I discuss the main non-phenomenological, theoretical argument for this claim: the so-called “transcendental argument” for universal mineness (Zahavi 2018, p. 711), which, in essence, corresponds to Shoemaker’s critique of the perceptual model of self-consciousness. I point out the potential of the transcendental argument, but most importantly its limitations. And I show that, even if successful, the argument cannot vindicate (...) the claim of an essential connection between phenomenal consciousness and self-consciousness. Since the transcendental argument is depicted as the “central argument” for universal mineness (Zahavi 2018, p. 711), I contend that, in view of its failure, the claim that all of my experiences have to be given to me _as mine_, all of your experiences have to be given to you _as yours_, etc., appears insufficiently substantiated. The idea that there is an essential connection between phenomenal consciousness and self-consciousness must be called into question. (shrink)

This paper controverts the ability of intentionalism about perception to account for unique epistemic significance of phenomenal consciousness. More specifically, the intentionalist cannot explain the latter without denying two well-founded claims: the transparency of experience, and the possibility of unconscious perception. If they are true, intentionality of perception entails that phenomenal consciousness has no special epistemic role to play. Although some intentionalists are ready to bite this bullet, by doing so they effectively undermine one of the standard motivations of their (...) view, i.e. the claim that perceptual experiences justify beliefs. Consequently, whatever reason might there be to think that phenomenal consciousness has unique epistemic import, it is also a reason to reject intentionalism. I recommend replacing the latter with an unorthodox formulation of relationalism about perception. (shrink)

Many philosophers have understood the representational dimension of affective states along the model of perceptual experiences. This paper argues affective experiences involve a kind of personal level affective representation disanalogous from the representational character of perceptual experiences. The positive thesis is that affective representation is a non-transparent, non-sensory form of evaluative representation, whereby a felt valenced attitude represents the object of the experience as minimally good or bad, and one experiences that evaluative standing as having the power to causally motivate (...) the relevant attitude. I show how this view can make sense of distinctive features of affective experiences, such as their valence and connection to value in a way which moves beyond current evaluativist views of affect.

In the last decade, Guilio Tononi has developed the Integrated Information Theory (IIT) of consciousness. IIT postulates that consciousness is equal to integrated information (Φ). The goal of this paper is to show that IIT fails in its stated goal of quantifying consciousness. The paper will challenge the theoretical and empirical arguments in support of IIT. The main theoretical argument for the relevance of integrated information to consciousness is the principle of information exclusion. Yet, no justification is given to support (...) this principle. Tononi claims there is significant empirical support for IIT, but this is called into question by the creation of a trivial theory of consciousness with equal explanatory power. After examining the theoretical and empirical evidence for IIT, arguments from philosophy of mind and epistemology will be examined. Since IIT is not a form of computational functionalism, it is vulnerable to fading/dancing qualia arguments. Finally, the limitations of the phenomenological approach to studying consciousness are examined, and it will be shown that IIT is a theory of protoconsciousness rather than a theory of consciousness.

The most widely endorsed philosophical and scientific theories of consciousness assume that it contributes a single functional capacity to an organism’s information processing toolkit. However, conscious processes are a heterogeneous class of psychological phenomena supported by a variety of neurobiological mechanisms. This suggests a plurality of functional contributions of consciousness (FCCs), in the sense that conscious experience facilitates different functional capacities in different psychological domains. In this paper, I first develop a general methodological framework for isolating the psychological functions that (...) are associated with conscious experience. I then use this to show that the leading accounts—Global Workspace Theories, Higher Order Thought Theory and Information Integration Theory—all fail to acknowledge this functional pluralism, which limits their applicability as theories of consciousness.

If moral status depends on the capacity for consciousness, what kind of consciousness matters exactly? Two popular answers are that any kind of consciousness matters (Broad Sentientism), and that what matters is the capacity for pleasure and suffering (Narrow Sentientism). I argue that the broad answer is too broad, while the narrow answer is likely too narrow, as Chalmers has recently argued by appeal to ‘philosophical Vulcans’. I defend a middle position, Motivational Sentientism, on which what matters is motivating consciousness: (...) any kind of consciousness which presents its subject with reasons for action. (shrink)

The book’s core argument is that an artificial intelligence that could equal or exceed human intelligence—sometimes called artificial general intelligence (AGI)—is for mathematical reasons impossible. It offers two specific reasons for this claim: Human intelligence is a capability of a complex dynamic system—the human brain and central nervous system. Systems of this sort cannot be modelled mathematically in a way that allows them to operate inside a computer. In supporting their claim, the authors, Jobst Landgrebe and Barry Smith, marshal evidence (...) from mathematics, physics, computer science, philosophy, linguistics, and biology, setting up their book around three central questions: What are the essential marks of human intelligence? What is it that researchers try to do when they attempt to achieve "artificial intelligence" (AI)? And why, after more than 50 years, are our most common interactions with AI, for example with our bank’s computers, still so unsatisfactory? Landgrebe and Smith show how a widespread fear about AI’s potential to bring about radical changes in the nature of human beings and in the human social order is founded on an error. There is still, as they demonstrate in a final chapter, a great deal that AI can achieve which will benefit humanity. But these benefits will be achieved without the aid of systems that are more powerful than humans, which are as impossible as AI systems that are intrinsically "evil" or able to "will" a takeover of human society.

An alternative model of the relation between consciousness and self-consciousness is proposed. The model combines a non-standard version of the higher-order theory of consciousness with the global neuronal workspace theory and argues that implicit higher-order self-awareness is a pervasive feature of the globally integrative states formed in the global workspace.

What connection is there between linguistic sounds and meaning? The present study claims that there is no such connection, and that linguistic sounds are the same as meaning. It is traditionally accepted that there is an arbitrary association between linguistic sounds and meaning. In the present paper, drawing from the concept of language authority for mind, I will talk about a distinction between live time of understanding - in which linguistic sounds are produced and understood - and non-live or historical (...) time of understanding. Through making this distinction, I will show that in live time of understanding, assuming any relationship between the mental state of linguistic sounds and that of meaning is inadequate, and that the best way to explain why linguistic sounds are understood instantly and effortlessly as soon as they are heard is to imagine that linguistic sounds are the same as meaning or that at least we are only faced with a single sound-meaning mental state. In addition, making a comparison between hearing linguistic sounds and seeing objects helps us consider linguistic sounds the same as meaning in the context of live time of understanding. (shrink)

Definitions of animal welfare often invoke consciousness or sentience. Marian Stamp Dawkins has argued that to define animal welfare this way is a mistake. In Dawkins’s alternative view, an animal with good welfare is one that is healthy and “has what it wants.” The dispute highlights a source of strain on the concept of animal welfare: consciousness-involving definitions are better able to capture the normative significance of welfare, whereas consciousness-free definitions facilitate the validation of welfare indicators. I reflect on how (...) the field should respond to this strain, ultimately recommending against splitting the concept and in favor of consciousness-involving definitions. (shrink)

According to unconscious perception hypothesis (UP), mental states of the same fundamental kind as ordinary conscious seeing can occur unconsciously. The proponents of UP often support it with empirical evidence for a more specific hypothesis, according to which colours can be seen unconsciously (UPC). However, UPC is a general claim that admits of many interpretations. The main aim of this paper is to determine which of them is the most plausible. To this end, I investigate how adopting various conceptions of (...) colour and perceptual phenomenal character affects UPC’s resilience to objections. This brings me to the conclusion that the most plausible reading of UPC is the one according to which the phenomenal character of colour perception (i) is constituted by colours qua primitive mind-independent qualities of the environment and (ii) is not essentially tied to consciousness. My conclusion not only identifies the most plausible interpretation of UPC, but also highlights and supports an unorthodox version of the relational theory of perception, which is a perfectly viable yet so far overlooked stance in the debate about unconscious perception.

There is a strong intuition that a zombie’s life is never good or bad for the zombie. What explains this?

In questo lavoro distinguo tra due versioni della tesi del carattere incarnato della mente: “debole” e “forte”. Secondo la versione debole, il possesso di stati mentali presuppone l’esistenza di un corpo che si muove ed agisce nell’ambiente, ossia un corpo funzionale. Secondo la versione forte, invece, il possesso di stati mentali presuppone l’esistenza di un corpo non solo funzionale ma anche senziente, ossia: il corpo come sede della sensibilità o coscienza fenomenica. Sostengo che alcuni approcci all’interno della “scienza cognitiva incarnata” (...) implicano la forma debole di embodiment : la robotica di Brooks, l’enattivismo sensomotorio di Noë e O’Regan e l’enattivismo radicale di Hutto e Myin. In contrapposizione a queste prospettive, e basandomi sull’analisi fenomenologica della corporeità vivente e vissuta, difendo la forma forte di embodiment, secondo cui la mente si fonda essenzialmente sul corpo funzionale e senziente. Parole chiave: Fenomenologia; Embodiment; Coscienza fenomenica; Enattivismo; Qualità sensibili -/- Abstract (english) -/- Functional body and sentient body. The strong view on the embodied mind in phenomenology: In this paper, I draw a distinction between weak and strong versions of the “embodiment thesis”. The weak version claims that mental states are grounded in a body that moves and acts in the environment, i.e., a functional body. The strong version claims that mental states are grounded in a body that is not only functional but also sentient, i.e., a body that is the locus of sensibility or phenomenal consciousness. I argue that some approaches within the “new embodied cognitive science” – Brooks’ robotics, Noë’s and O’Regan’s sensorimotor enactivism, Hutto’s and Myin’s radical enactivism – imply a weak version of the embodiment thesis. In contrast, by drawing on a phenomenological analysis of living and lived corporeality, I argue for the strong version, which claims that the mind is essentially grounded in the functional and sentient body. Keywords: Phenomenology; Embodiment; Phenomenal Consciousness; Enactivism; Sensible Qualities. (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)

In Section I, I clarify turning point issues in the Phillips and Block debate about whether there is unconscious perception. These include questions about whether uptake of certain visual information is an individual or person level accomplishment, as required for genuine unconscious _perceiving_. Section II takes up a recent reorientation proposed in Block ( 2017 ) towards the question of whether there is unconscious perceiving, where we are to look for the pervasive role of unconscious perceiving in, perhaps especially, the (...) online control of everyday reaching and grasping. I point out that while this may well be a helpfully different approach to explore, it does not evade the central questions and challenges familiar from the prior debate between Phillips and Block. Section III reviews an approach summarized in Dehaene ( 2014 ), drawing from a range of measures of neural activity. Dehaene provides evidence of quite rich non-conscious perceptual system responses, some arguably individual or person level. But in a fairly thin or fragile way, absent taking up, in higher level assessment, the information encoded in initial visual response. Or that is the interpretation I argue for, in relating the Dehaene account to the Phillips and Block debate, in a way that illuminates the Phillips and Block discussions. An Appendix provides an overview of debates in the literature about the Goodale and Milner Two Visual Systems Hypothesis, that Block ( 2017 ) makes central appeal to. (shrink)

How are attention and consciousness related? Can we learn what the contents of someone’s consciousness are if we know the targets of their attention? What can we learn about the contents of consciousness if we know the targets of attention? Although introspection might suggest that attention and consciousness are intimately connected, a good body of recent findings in cognitive psychology and cognitive neuroscience brings compelling reasons to believe that they are two separate and independent processes. This paper attempts to bring (...) attention and consciousness back together to make the study of attentional distributions an essential ingredient for the study of the contents of consciousness. My proposal has two main components. First, I introduce a framework for systematizing the relations between attention in its different forms and consciousness in its different forms. Although philosophers and cognitive scientists have repeatedly highlighted the importance of such systematization, most details are still to be worked out. Here I take an initial stab at this project based on the notion of degrees of informational enhancement. Second, I introduce the notion of vicarious attention to account for a kind of additional processing benefit that comes for free when attention is allocated to a target. I then propose that this kind of processing must also be considered when mapping attention targets into contents of consciousness. (shrink)

I first clarify the idea that blameworthiness requires consciousness as the view that one can be blameworthy only for what is a response to a reason of which one is conscious. Next I develop the following argument: blameworthiness requires exercising control in a way distinctive of persons and doing this, in view of what it is to be a person, requires responding to a reason of which one is conscious. Then I defend this argument from an objection inspired by Arpaly (...) and Schroeder according to which responding to moral reasons suffices for exercising control distinctive of persons. (shrink)

‘Sentience’ sometimes refers to the capacity for any type of subjective experience, and sometimes to the capacity to have subjective experiences with a positive or negative valence, such as pain or pleasure. We review recent controversies regarding sentience in fish and invertebrates and consider the deep methodological challenge posed by these cases. We then present two ways of responding to the challenge. In a policy-making context, precautionary thinking can help us treat animals appropriately despite continuing uncertainty about their sentience. In (...) a scientific context, we can draw inspiration from the science of human consciousness to disentangle conscious and unconscious perception (especially vision) in animals. Developing better ways to disentangle conscious and unconscious affect is a key priority for future research. (shrink)

Is a human more conscious than an octopus? 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)

Illusionism is the thesis that phenomenal consciousness does not exist, but merely seems to exist. Many opponents to the thesis take it to be obviously false. They think that they can reject illusionism, even if they conceded that it is coherent and supported by strong arguments. David Chalmers has articulated this reaction to illusionism in terms of a “Moorean” argument against illusionism. This argument contends that illusionism is false, because it is obviously true that we have phenomenal experiences. I argue (...) that this argument fails by showing that its defenders cannot maintain that its crucial premise has the kind of support needed for the argument to work, without begging the question against illusionism.

This article proposes a methodological schema for engaging in a productive discussion of ethical issues regarding human brain organoids, which are three-dimensional cortical neural tissues created using human pluripotent stem cells. Although moral consideration of HBOs significantly involves the possibility that they have consciousness, there is no widely accepted procedure to determine whether HBOs are conscious. Given that this is the case, it has been argued that we should adopt a precautionary principle about consciousness according to which, if we are (...) not certain whether HBOs have consciousness—and where treating HBOs as not having consciousness may cause harm to them—we should proceed as if they do have consciousness. This article emphasizes a methodological advantage of adopting the precautionary principle: it enables us to sidestep the question of whether HBOs have consciousness and, instead, directly address the question of what kinds of conscious experiences HBOs can have, where the what-kind-question is more tractable than the whether-question. By addressing the what-kind-question, we will be able to examine how much moral consideration HBOs deserve. With this in mind, this article confronts the what-kind-question with the assistance of experimental studies of consciousness and suggests an ethical framework which supports restricting the creation and use of HBOs in bioscience.

The Integrated Information Theory (IIT) formulated for the first time in 2004 by the neuroscientist Giulio Tononi, is a theoretical framework aiming to scientifically explain phenomenal consciousness. The IIT is presented in the first part of this work. Broadly speaking, integrated information is an abstract quantitative measure of the causal power a system has on itself. The main claim of IIT is the identity between informational structures and experience. The nature of this identity will be the subject of the second (...) part. One can interpret the IIT as a fundamental law of nature connecting the physical domain to the mental domain. The philosophical implications of such a claim are numerous and they are subject to criticism. This will be the main concern of the third and last part. (shrink)

Is it possible to build a conscious machine, an artifact that has qualitative experiences such as feeling pain, seeing the redness of a flower or enjoying the taste of coffee ? What makes such experiences conscious is their phenomenal character: it is like something to have such experiences. In contemporary philosophy of mind, the question of the qualitative aspect of conscious experiences is often addressed in terms of qualia. In a pre-theoretical and intuitive sense, qualia refer to the phenomenal character (...) or “what-it’s-like-ness” of a conscious experience: the painfulness of a pain experience or the redness of a visual experience of a red object. The problem of artificial qualia is the question of the theoretical possibility of the realization of qualia by artifacts. In this work, this problem will serve as a methodological tool to address what is arguably the most fundamental question of philosophy of mind: what exactly is consciousness? (shrink)

If we were to connect two individuals’ brains together, how would this affect the individuals’ conscious experiences? In particular, it is possible for two people to share any of their conscious experiences; to simultaneously enjoy some token experiences while remaining distinct subjects? The case of the Hogan twins—craniopagus conjoined twins whose brains are connected at the thalamus—seems to show that this can happen. I argue that while practical empirical methods cannot tell us directly whether or not the twins share conscious (...) experiences, considerations about the locality of content processing in the brain entails that they most likely do so.

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.

Most people believe that consciousness is real. But illusionists say it isn’t—they say consciousness is an illusion. One common illusionist strategy for defending their view involves a debunking argument. They explain why people _believe_ that consciousness exists in a way that doesn’t imply that it _does_ exist; and, in so doing, they aim to show that that belief is unjustified. In this paper I argue that we can know consciousness exists even if these debunking arguments are sound. To do this, (...) I draw on the claim that some knowledge is constituted, not by beliefs in propositions, but by awareness of properties and objects. Then I argue that accepting this claim allows us to evade illusionists’ debunking arguments by allowing us to hold that our knowledge of consciousness does not depend solely on potentially debunked _beliefs_ in consciousness. Finally, while considering potential illusionist responses, I suggest that my strategy also yields a plausible account of our most basic knowledge of consciousness and an explanation for why so few people accept illusionism even when they have (or had) no decisive reply to illusionists’ arguments.

Clark and Chalmers propose that the mind extends further than skin and skull. If they are right, then we should expect this to have some effect on our way of knowing our own mental states. If the content of my notebook can be part of my belief system, then looking at the notebook seems to be a way to get to know my own beliefs. However, it is at least not obvious whether self-ascribing a belief by looking at my notebook (...) is a case of introspection the same way that knowing my non-extended beliefs is. Traditionally this sort of introspection is thought to be privileged and special in ways that the extended introspection case seems not to be. There is nothing privileged about looking at my notebook. Anyone could do it. The aim of the paper is to find out how to understand extended introspection and whether there is something privileged and special about knowing one’s own extended beliefs. Moreover, the notebook case has close analogs using twenty-first century technology. It seems possible to know our beliefs that are extended to smartphones, wearable technology or a cloud-based data store. First, I present the case of extended introspection. I then discuss whether it should be understood as ordinary introspection or as mind-reading. Both seem to be bad fits, which finally prompts an original account for extended introspection based on epistemic rules. (shrink)

Bayne and McClelland (2016) raise the matching content challenge for proponents of cognitive phenomenology: if the phenomenal character of thought is determined by its intentional content, why is it that my conscious thought that there is a blue wall before me and my visual perception of a blue wall before me don’t share any phenomenology, despite their matching content? In this paper, I first show that the matching content challenge is not limited to proponents of cognitive phenomenology but extends to (...) cases of cross-modal perception, threatening representationalism about consciousness in general. I then give two responses to the challenge, both of which appeal to intentional modes. The difference in intentional mode between a thought and a visual perception can either explain why we should not expect any phenomenal overlap between the two experiences, or it can make it clear why the phenomenal overlap is easy to overlook. I show that these responses are available to the representationalist about perceptual consciousness, as well as the proponent of cognitive phenomenology. The upshot is that, when it comes to the matching content challenge, both perceptual representationalism and cognitive representationalism stand on equal dialectical footing. (shrink)

Our ordinary conception of imagination takes it to be essentially a conscious phenomenon, and traditionally that’s how it had been treated in the philosophical literature. In fact, this claim had often been taken to be so obvious as not to need any argumentative support. But lately in the philosophical literature on imagination we see increasing support for the view that imagining need not occur consciously. In this paper, I examine the case for unconscious imagination. I’ll consider four different arguments that (...) we can find in the recent literature—three of which are based on cases and one that is based on considerations relating to action guidance. To my mind, none of these arguments is successful. I conclude that the case for postulating unconscious imagining has not yet been well motivated. (shrink)
