Kant's most sustained discussion of obscure representations can be found in the first book of his Anthropology from a Pragmatic Point of View. What is puzzling is that in the middle of the section devoted to the topic, Kant asserts that “because this field can only be perceived in his passive side as a play of sensations, the theory of obscure representations belongs only to physiological anthropology, and so it is properly disregarded here.” So, do obscure representations belong to pragmatic (...) anthropology or not? Kant's official position is that they do not, yet the textual evidence—we find discussions of obscure representations in 20 years of his work on pragmatic anthropology—suggests that they do, in fact, belong here. Most of the literature on obscure representations focuses on their contribution to cognition and none has clarified what it would mean to assume a “pragmatic point of view” on obscure representations, and to study them in the context of pragmatic anthropology. My aim in this paper is to provide such clarification, focusing on Kant's discussion of our propensity to “play with” obscure representations and what he calls our “art of obscuring.”. (shrink)

It is commonly assumed that where consciousness is present, it is a single stream. This notion is bolstered by functions attributed to consciousness, particularly providing multi-faceted experience of a perceptual scene and contributing to the production of coherent behavior, which supposedly require consciousness to be unitary. It is believed that were the unitary structure of consciousness to break down, such that multiple streams of consciousness are present, these functions would be compromised. The split-brain syndrome is widely regarded as evidence for (...) this claim. However, the split-brain syndrome is an atypical structure of human consciousness. As such, conclusions based on the split-brain syndrome regarding the structure and functions of consciousness may be limited in generalizability. There may be cases where multiple consciousness is neither maladaptive nor anomalous but is the naturally evolved configuration, and thus may not compromise the capacity of consciousness to subserve multi-faceted experience and coherent behavior. This paper speculates on the different forms multiple consciousness may take, and demonstrates how they may be able to implement the aforementioned functions of consciousness. In doing so, the paper demonstrates that the commitment a unitary model of consciousness may be due more to anatomical constraints than functional ones. (shrink)

We present a new argument in favor of the Awareness Principle, the principle that one is always aware of one’s concurrent conscious states. Informally, the argument is this: (1) Your conscious states are such that you can attend to them without undertaking any action _beyond mere shift of attention_; but (2) You cannot come to attend to something without undertaking any action beyond mere shift of attention unless you are already aware of that thing; so, (3) Your conscious states are (...) such that you are aware of them. We open by introducing more fully the Awareness Principle (§ 1) and explicating the crucial notion of “mere shift of attention” (§ 2). We then develop the argument more fully, first in an intuitive form (§ 3) and then more formally (§ 4), before replying to a series of objections (§§ 5–7). (shrink)

Psychological and philosophical studies have extended J. J. Gibson’s notion of affordances. Affordances are possibilities for bodily action presented to us by the objects of our perception. Recent work has argued that we should extend the actions afforded by perception to mental action. I argue that we can extend the notion of affordance itself. What I call ‘Introspective Affordances’ are possibilities for mental action presented to us by introspectively accessible states. While there are some prima facie worries concerning the non-perceptual (...) nature of introspection, I will argue that our internal mental lives share enough commonalities with experiences in our environment to warrant this extension. I will demonstrate the value of introspective affordances by showing how they allow us to explain an underexplored aspect of thought insertion. (shrink)

In 'Ethics Without Sentience: Facing Up to the Probable Insignificance of Phenomenal Consciousness' (Kammerer, 2022), I argued that phenomenal consciousness is probably normatively insignificant, and does not play a significant normative role. In 'Preserving the Normative Significance of Sentience' (Dung, 2024), Leonard Dung challenges my reasoning and defends sentientism about value and moral status against my arguments. Here I respond to Dung's criticism, pointing out three flaws in his reply. My conclusion is that the view that phenomenal consciousness is distinctively (...) significant is still very much under threat. (shrink)

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

In Open Minded: Searching for Truth about the Unconscious Mind, Ben R. Newell & David R. Shanks (henceforth, N&S) challenge the popular claim that much of human judgment and decision-making is explained by unconscious processes...

Process aspects are prevalent in many domains of reality, and consciousness is no exception. Nevertheless, while the processual approach implicitly underlies the theories of consciousness, an explicit statement of the question is scarcely found in the literature. This paper tries to bridge this gap. Here, I argue that conscious experience fulfils all the requirements for a processual analysis: it is complex, functionally/causally determined, and has a temporal basis. Then, I revisit an old concept, self-transformative processes, which refers to processes that (...) change themselves. These processes are very common. A stretched bow is the classical Heraclitean example. However, it is easy to misunderstand what self-transformativeness is. To provide a well-formed description, I characterize self-transformative processes in terms of composition (using a non-classic mereology) and in terms of functionality (by developing the concept of self-modulating variables). Finally, I apply self-transformative processes to explain consciousness. Traces of self-transformativeness can be found in many theories of consciousness, particularly when they are stressed about their internal mechanisms. Here, I focus on Integrated Information Theory as a paradigmatic example of a mathematically well-described theory, and I demonstrate that quantitative self-transformativeness is a requirement at the very core of the integration of the information.

How all philosophical explanations of human consciousness and the fundamental structure of the cosmos are bizarre—and why that’s a good thing Do we live inside a simulated reality or a pocket universe embedded in a larger structure about which we know virtually nothing? Is consciousness a purely physical matter, or might it require something extra, something nonphysical? According to the philosopher Eric Schwitzgebel, it’s hard to say. In The Weirdness of the World, Schwitzgebel argues that the answers to these fundamental (...) questions lie beyond our powers of comprehension. We can be certain only that the truth—whatever it is—is weird. Philosophy, he proposes, can aim to open—to reveal possibilities we had not previously appreciated—or to close, to narrow down to the one correct theory of the phenomenon in question. Schwitzgebel argues for a philosophy that opens. According to Schwitzgebel’s “Universal Bizarreness” thesis, every possible theory of the relation of mind and cosmos defies common sense. According to his complementary “Universal Dubiety” thesis, no general theory of the relationship between mind and cosmos compels rational belief. Might the United States be a conscious organism—a conscious group mind with approximately the intelligence of a rabbit? Might virtually every action we perform cause virtually every possible type of future event, echoing down through the infinite future of an infinite universe? What, if anything, is it like to be a garden snail? Schwitzgebel makes a persuasive case for the thrill of considering the most bizarre philosophical possibilities. (shrink)

When you have a conscious experience—such as feeling pain, watching the sunset, or thinking about your loved ones—are you aware of the experience as your own, even when you do not reflect on, think about, or attend to it? Let us say that an experience has “mineness” just in case its subject is aware of it as her own while she undergoes it. And let us call the view that all ordinary experiences have mineness “typicalism.” Recently, Guillot has offered a (...) novel argument for typicalism by leveraging the relation between self-knowledge and self-awareness. She starts by arguing that all ordinary experiences give their subjects immediate justification to believe that their experiences are their own. She then argues that this can be explained by typicalism. In this paper, I argue that her argument fails. I start by clarifying the notion of mineness and giving more details about her argument. I then explain why her argument fails by raising doubts about whether typicalism explains the target explanandum. I close by considering some implications of our discussion for self-knowledge.

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)

Organoids and specifically human cerebral organoids (HCOs) are one of the most relevant novelties in the field of biomedical research. Grown either from embryonic or induced pluripotent stem cells, HCOs can be used as in vitro three-dimensional models, mimicking the developmental process and organization of the developing human brain. Based on that, and despite their current limitations, it cannot be assumed that they will never at any stage of development manifest some rudimentary form of consciousness. In the absence of behavioral (...) indicators of consciousness, the theoretical neurobiology of consciousness being applied to unresponsive brain-injured patients can be considered with respect to HCOs. In clinical neurology, it is difficult to discern a capacity for consciousness in unresponsive brain-injured patients who provide no behavioral indicators of consciousness. In such scenarios, a validated neurobiological theory of consciousness, which tells us what the neural mechanisms of consciousness are, could be used to identify a capacity for consciousness. Like the unresponsive patients that provide a diagnostic difficulty for neurologists, HCOs provide no behavioral indicators of consciousness. Therefore, this article discusses how three prominent neurobiological theories of consciousness apply to human cerebral organoids. From the perspective of the Temporal Circuit Hypothesis, the Global Neuronal Workspace Theory, and the Integrated Information Theory, we discuss what neuronal structures and functions might indicate that cerebral organoids have a neurobiological capacity to be conscious.

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 argue that metaethical experientialism yields genuine counterexamples to the principle that no ethical conclusion can be derived from purely descriptive premises. I also discuss the prospects for a pluralistic metaethics, whereby different metaethical theories hold (...) for different classes of ethical facts. (shrink)

Lockean views of personal identity maintain that we are essentially persons who persist diachronically by virtue of being psychologically continuous with our former selves. In this article, I present a novel objection to this variant of psychological accounts, which is based on neurophysiological characteristics of the brain. While the mental states that constitute said psychological continuity reside in the cerebral hemispheres, so that for the former to persist only the upper brain must remain intact, being conscious additionally requires that a (...) structure originating in the brainstem—the ascending reticular activating system—be functional. Hence, there can be situations in which even small brainstem lesions render individuals irreversibly comatose and thus forever preclude access to their mental states, while the neural correlates of the states themselves are retained. In these situations, Lockeans are forced to regard as fulfilled their criterion of diachronic persistence since psychological continuity, as they construe it, is not disrupted. Deeming an entity that is never again going to have any mental experiences to be a person, however, is an untenable position for a psychological account to adopt. In their current form, Lockean views of personal identity are therefore incompatible with human neurophysiology. (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.

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.

What occurs in the mind of an expert who is performing at their very best? In this paper, I survey the history of debate concerning this question. I suggest that expertise is neither solely a mastery of the automatic nor solely a mastery of intelligence in skilled action control. Experts are also capable of performing automatic actions intelligently. Following this, I argue that unconscious-thought theory (UTT) is a powerful tool in coming to understand the role of executive, intelligent action control (...) in the fluidly automatic performance of expertise. Relying on a body of empirical evidence concerning the cognitive structures and perceptual strategies employed by experts, I show that the realm of skilled action is an ideal environment within which the powers of unconscious cognitive processing can have positive effects on action. I conclude that experts rely upon unconscious thinking in the production of intelligently automatic skilled actions. (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)

A widely shared view in the literature on first-person thought is that the ability to entertain first-person thoughts requires prior non-conceptual forms of self-consciousness. Many philosophers maintain that the distinctive awareness which accompanies the use of the first person already presupposes a non-conceptual consciousness of the fact that oneself is the owner of a first-person thought. I call this argument The Argument for Non-Conceptual Self-Consciousness based on the Meaning of “I” and will demonstrate that most proponents of the presented argument (...) fail to establish their conclusion, even though I believe that the conclusion is actually true. The argument only justifies the claim that contextual information is needed in order to recognize oneself as the referent of an occurrence of the first person. However, it does not justify the thesis that this information needs to be given consciously and thus the existence of any non-conceptual self-consciousness. Finally, I shall present an argument for the assumption that some form of self-consciousness is needed to reflexively think about oneself via the first-person concept. In order to do so, I will draw on the general discussion about the functional role of consciousness. In particular, I will rely on results recently proposed by Frith and Metzinger (2016), Frith (Pragmatics & Cognition 18:497–551, 2010, Cognitive Neuroscience 2:117–118, 2011), Graziano (2013, Frontiers in Robotics and AI 4:article 60, 2017), and Graziano and Kastner (Cognitive Neuroscience 2:98–113, 2011), which suggest that one of the central functions of consciousness is to provide information about mental states for communication.

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.

Certain contemporary philosophers have thought that the first-person, qualitative aspect of conscious experience should be taken seriously when it comes to our thinking about personal identity through time. These philosophers have thus argued that experiential continuity is essential to a person’s ability to persist identically through time. This is what I will call ‘the phenomenological theory’. In this thesis I describe the phenomenological theory and then discuss three problems that have plagued the history of this theory: the bridge problem, the (...) token problem, and the ontological problem. I will argue that a recent version of the phenomenological theory proposed by Barry Dainton and Timothy Bayne provides satisfactory answers to two of these problems, but not the third. I will conclude this thesis by proposing a superior version of the phenomenological theory—one that can handle all three problems. (shrink)

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.

In the cognitive neuroscience of consciousness, participants have commonly been instructed to report their conscious content. This, it was claimed, risks confounding the neural correlates of consciousness (NCC) with their preconditions, i.e., allocation of attention, and consequences, i.e., metacognitive reflection. Recently, the field has therefore been shifting towards no-report paradigms. No-report paradigms draw their validity from a direct comparison with no-report conditions. We analyze several examples of such comparisons and identify alternative interpretations of their results and/or methodological issues in all (...) cases. These go beyond the previous criticism that just removing the report is insufficient, because it does not prevent metacognitive reflection. The conscious mind is fickle. Without having much to do, it will turn inward and switch, or timeshare, between the stimuli on display and daydreaming or mind-wandering. Thus, rather than the NCC, no-report paradigms might be addressing the neural correlates of conscious disengagement. This observation reaffirms the conclusion that no-report paradigms are no less problematic than report paradigms. (shrink)

In recent decades, the scientific study of consciousness has significantly increased our understanding of this elusive phenomenon. Yet, despite critical development in our understanding of the functional side of consciousness, we still lack a fundamental theory regarding its phenomenal aspect. There is an “explanatory gap” between our scientific knowledge of functional consciousness and its “subjective,” phenomenal aspects, referred to as the “hard problem” of consciousness. The phenomenal aspect of consciousness is the first-person answer to “what it’s like” question, and it (...) has thus far proved recalcitrant to direct scientific investigation. Naturalistic dualists argue that it is composed of a primitive, private, non-reductive element of reality that is independent from the functional and physical aspects of consciousness. Illusionists, on the other hand, argue that it is merely a cognitive illusion, and that all that exists are ultimately physical, non-phenomenal properties. We contend that both the dualist and illusionist positions are flawed because they tacitly assume consciousness to be an absolute property that doesn’t depend on the observer. We develop a conceptual and a mathematical argument for a relativistic theory of consciousness in which a system either has or doesn’t have phenomenal consciousness with respect to some observer. Phenomenal consciousness is neither private nor delusional, just relativistic. In the frame of reference of the cognitive system, it will be observable and in other frame of reference it will not. These two cognitive frames of reference are both correct, just as in the case of an observer that claims to be at rest while another will claim that the observer has constant velocity. Given that consciousness is a relativistic phenomenon, neither observer position can be privileged, as they both describe the same underlying reality. Based on relativistic phenomena in physics we developed a mathematical formalization for consciousness which bridges the explanatory gap and dissolves the hard problem. Given that the first-person cognitive frame of reference also offers legitimate observations on consciousness, we conclude by arguing that philosophers can usefully contribute to the science of consciousness by collaborating with neuroscientists to explore the neural basis of phenomenal structures.

There is a strong intuition that a zombie’s life is never good or bad for the zombie. What explains this? In this paper, I consider five possible explanations of the intuition that a zombie’s life is never worth living, plus the option of rejecting the intuition. I point out the considerable costs of each option, though making clear which option strikes me as least problematic.

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)

Philosophers and scientists refer to the special character of phenomenal consciousness, something supposedly obvious to all conscious persons. However, we had no empirical evidence about the folk view of consciousness until the first studies were carried out in the experimental philosophy of consciousness. According to the leading interpretation of these results, laypersons—people without academic knowledge about consciousness—do not notice the phenomenal aspect of consciousness. The aim of the article is to answer the question of whether we can trust these results. (...) I show that there are serious doubts about the validity of the experimental philosophy of consciousness research. As a result, the leading interpretation should be rejected, and the question about the folk nature of the concept of consciousness must be regarded as open. (shrink)

The groundbreaking, viewpoint theory of Merker et al. explains several properties of the conscious field, including why the observer cannot directly apprehend itself. We propose that viewpoint theory might also provide a progressive, constitutive marker of consciousness and shed light on why most of the contents of consciousness are encapsulated.

Merker et al. argue that integrated information theory is not a theory of consciousness because the IIT formalism does not match phenomenology. I argue that the authors ultimately fail to articulate the problem of the inference of the postulates from the axioms. I suggest a different version of this problem, and argue that this can help rethink IIT's potential for consciousness science.

The problem of higher-order misrepresentation poses a dilemma for the higher-order theory of consciousness. The two ways of conceiving of the theory each run into a different difficulty raised by the problem of misrepresentation. If the theory is conceived relationally, i.e., conceived so as the higher-order state causes or makes a first-order state conscious, then the theory faces a problem raised by Block concerning the implausibility of non-existent conscious states. If conceived non-relationally, i.e., conceived in such a way as it (...) is the higher-order state itself which is the conscious state, then consideration of Neander’s original misrepresentation problem, that this seems to make the first-order state a spinning wheel in the explanation of consciousness, raises the conceptual problem that this version of the higher-order theory seems not to offer a philosophical theory of consciousness that is distinct from the first-order theory.

‘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)
