Explaining Consciousness?

In passing remarks, some commentators have noted that for Nagel, physicalism is true. It has even been argued that Nagel seeks to find the best path to follow to achieve future physicalism. I advance these observations by adding that for Nagel, we should discuss the consciousness problem not in terms of physical and mental issues but in terms of our desire to include consciousness in an objective/scientific account, and we can achieve this only by revising our self-conception, i.e., folk psychology, (...) to develop a more detached view of experience. Through the project of objective phenomenology, Nagel aims to achieve some sort of objective, detached, and scientific explanation of the subjective nature of experience. This project seeks to make the truth of physicalism intelligible and consciousness more amenable to scientific study, potentially raising an even broader concept than the one physicalism originally proposes.

Conscious experience has been said to be outside of, or alien to, physics, and unexplained in a physical world. However, it is argued here that experience is entirely expected in a physical world that can only be defined by its power to determine patterns of experience. Something physical is something with the type of causal power that can contribute to determining the content of an experience if a subject is present at the right place and time. Physical powers also interact (...) with other physical powers, distant from any given subject, to form chains, and it is these interactions that physics handles mathematically. Nevertheless, actual causation is always defined by reference to determination of experience. The apparent puzzle of why there should be a link between experience and the physical may relate in part to the fact that experience is always immediately causally proximal, always 'here and now', at least as far as we can ascertain. Proximality, and with it the potential for mentality, cuts across existential/ ontological categories. Experience also requires a concept of an intrinsic individual, in order for there to be individual points of view. The practical problem for consciousness studies is to identify intrinsically individual causal units with event domains in human brains, that can have points of view and content that could fit with human experiences, in a way consistent with current physics. It is suggested that the 'causal diamond' concept of the here and now explored by Savitt (2015) and Arthur (2019), together with principles of field theory, may provide a useful starting point.

Quantum cognition is a new theoretical framework for constructing cognitive models based on the mathematical principles of quantum theory. Due to its increasing empirical success, one wonders what it tells us about the underlying process of cognition. Does it imply that we have quantum minds and there is some sort of quantum structure in the brain? In this paper, I address this important issue by using a new result in the research of quantum foundations. Based on the PBR theorem about (...) the reality of the wave function, I show, given certain assumptions, that the wave function assigned to a cognitive system such as our brain, which is used to calculate probabilities of thoughts/judgment outcomes in quantum cognition, is a real representation of the cognitive state of the system, not a mere representation of incomplete knowledge about the state of the system. This result supports a realist interpretation of quantum cognition, according to which the cognitive state of our brain and its dynamics are not classical but quantum in quantum cognition. In short, quantum cognition implies quantum minds. However, this result does not mean that we have quantum minds and our brain is a quantum computer, since quantum cognition by its standard formulation has not been fully confirmed by experiments. The hope is that more crucial experiments can be done in the near future to determine whether or not quantum cognition is real. (shrink)

The topic of synchronicity has long intrigued philosophers, scientists, and the general public. However, to date very little empirical research has explored the underlying mechanisms of synchronicity. In other words, why do synchronicities occur? Are synchronicities random, or do they hold clues about the ultimate nature of reality? Drawing on theoretical and empirical research, the current paper explores the idea that synchronicity might be one way that the fundamental (i.e. ontologically primary) nature of consciousness reveals itself to us in everyday (...) life, and that contemplative practices such as meditation might be capable of invoking synchronicity. In addition, this paper aims to summarize theoretical perspectives on synchronicity in an attempt to spark a renewed interest in conducting empirical research on this topic, arguing for a thoughtful consideration of post-materialist perspectives in an attempt to innovate within the field of consciousness studies and shed light on the ontological questions raised by synchronicity.

According to illusionism, phenomenal consciousness is an introspective illusion. The illusion problem is to explain the cause of the illusion, or why we are powerfully disposed to judge—erroneously—that we are phenomenally conscious. I propose a theory to solve the illusion problem. I argue that on the basis of three hypotheses about the mind—which I call introspective opacity, the infallibility intuition, and the justification constraint—we can explain our disposition, on introspection, to draw erroneous unconscious inferences about our sensory states. Being subject (...) to the illusion of phenomenal consciousness consists in having this disposition. I explain our ‘problem intuitions’ about consciousness —that our sensory states bear phenomenal properties that are qualitatively like something with which we are directly acquainted that is ineffable, atomic, intrinsic, private, and non-physical. I also address the illusion meta-problem, which is to explain why illusionism seems especially counterintuitive. (shrink)

This paper aims to present a theory of consciousness called the reversed theater theory, which gives the phenomenal consciousness a functional role in cognition. According to the theory, there is a theater in the brain, but a reversed Cartesian theater that the actors are the consciousness and the audience is the unconsciousness; actors mechanically act according to the script, while the audience enjoys its content. When a performance is over, the audience compiles the next script based on their experience so (...) that the stage continues. (shrink)

This article is based on a conversation between the President of the Society for the Anthropology of Consciousness and the Editor‐in‐Chief of its journal. The aim of this conversation is threefold: (1) to engage a broader audience within the field of the anthropology of consciousness, (2) to discuss the recent history of the organization and its current direction, and (3) to recognize why concrete efforts toward a practice of decolonization is essential to maintaining the relevance of an anthropology of consciousness.

The discussion of the nature of consciousness seems to have stalled, with the “hard problem of consciousness” in its center, well-defined camps of realists and eliminativists at two opposing poles, and little to none room for agreement between. Recent attempts to move this debate forward by shifting them to a meta-level have heavily relied on the notion of “intuition”, understood in a rather liberal way. Against this backdrop, the goal of this paper is twofold. First, we want to highlight how (...) the ontological and epistemological status of intuitions restricts the arguments in the debate on consciousness that rely on them. Second, we want to demonstrate how the deadlock in those debates could be resolved through a study of a particular, “positive” kind of intuitions. We call this approach “The Canberrish Plan for Consciousness” as it adopts elements of the methodological “Canberra Plan”. (shrink)

Recent arguments in plant biology that claim to be uncovering the scientific basis for sentience in plants are grounded on assumptions that have not been sufficiently scrutinized. This paper focuses on two assumptions in particular – the semantic assumption that psychological predicates are non-rigid and hence can be extended to plants, and the assumption that Darwinian gradualism is inconsistent with consciousness emerging at a specific place on the phylogenetic tree. We interrogate both assumptions, advocating that a careful semantic analysis of (...) psychological predicates does not warrant their extension to plants on the available evidence, and that gradualism and emergentism, properly construed, are not inconsistent.

The defining principle of evolutionary biology is that all species, extant and extinct, evolved from ancient prokaryotic cells. Their initial appearance and adaptive evolution are proposed to have been accompanied by a cellular sentience, by feelings, subjectivity or, in a word, 'consciousness'. Prokaryotic cells, such as archaea and bacteria, have natural unitary, valence-marked 'mental' representations. They process and evaluate sensory information in a context-dependent manner. They learn, establish memories, and communicate using biophysical fields acting on excitable membranes. Symbiotic eukaryotic cells, (...) which evolved much later, initiated a compound cellular subjectivity utilizing 'senomic' and 'ephaptic' principles that evolved into the varieties of consciousness seen in multicellular species. This Cellular Basis of Consciousness (CBC) model provides a novel framework within which to approach fundamental issues such as the origins of life and the emergence of mind. (shrink)

An enquiry into plant consciousness requires, on the one hand, taking into account recent experiments in plant biology and, on the other hand, refining the theoretical framework of behaviour and the various degrees of cognition. The main goal of this contribution is to advance such a framework by comparing classical animal and human cognition approaches with the theories of minimal cognition. This leads us to interpret more carefully the various plant activities and to highlight the limits of classical theories of (...) zoocentric cognition. In particular, the article shows that the notions of cognition and consciousness are often abusively confused, and with that of behaviour. Once this ambiguity is removed, it is possible to better distinguish several meanings of consciousness and to evaluate their relevance to plant activities. (shrink)

Are plants conscious? Most knowledgeable people say they aren't. A small minority say they are. Others say we don't know. Virtually all assume the predicate '– is conscious' is fully determinate; plants are or aren't in its extension. Appealing to Mark Wilson's work on predicates and concepts, I challenge that assumption, proposing that the predicate isn't determinate for plants. I offer the start of an explanation for why this is so. We tacitly rely on many empirical correlations when we correctly (...) characterize creatures as conscious, but we have limited knowledge of those facts, and plants differ significantly from animals, while also being substantively similar to them. We don't yet know what it would be for them to be conscious. (shrink)

Integrated information theory (IIT) is a candidate theory of consciousness that highlights the role of complex interactions between parts of a system as the basis of consciousness – and, due to its general information-theoretic formulation, is capable of making statements about consciousness in neural and non-neural systems alike. Here, we argue that a system radically different to a human brain, host to complex physiological and functional structures capable of integrating information, can be found in the meristems and vascular system of (...) higher plants. Following a pragmatic and ontologically innocent approach, neither taking for granted that plants are conscious nor dismissing the possibility that they are, we argue that the time is ripe to apply analysis tools inspired by IIT to plants, taking advantage of recent developments in both plant imaging and information theory. We introduce and discuss the relevant literature, and pro information and integration in plant behaviour, assessing the plausibility of plant sentience. If successful, these experiments could position plants as the next frontier in consciousness science, and urge us to rethink our perspectives on consciousness, how to measure it, and its prevalence amongst living beings.

The study of plant signaling and behaviour, whose aim is to address the physiological basis for adaptive behaviour in plants, is a growing and thought-provoking field of research. In this review we discuss relevant studies that try to interpret in a neurocognitive fashion cases in which plants seem to behave similarly to animals. By comparing observations and experiments about plants and animals, we propose a framework composed of three axes in which interactions of living organisms with the world can be (...) represented. The first axis refers to adaptiveness, the second to sensitivity, and the third to sentience. This model allows us to interpret the behaviours of living organisms along a continuum capable of giving a smooth transition from simple to complex responses. In light of this, plants show an excellent adaptiveness, a variable level of sensitivity, and a good degree of sentience (restricted to the immediate perception that something is happening to themselves). Only the organisms with a high degree of sentience can have the basis for developing consciousness. However, even though it is necessary for consciousness, sentience is not sufficient, as it must be associated with a complex functional organization of structures that can support a recursive and synchronized processing of information. So far, plants have been found to completely lack this type of organization. Plants appear to be, therefore, sentient but not conscious. (shrink)

The attribution of sentience or consciousness to plants is currently a topic of debate among biologists and philosophers. The claim that plants are conscious is based on three arguments: (i) plants, like all living organisms, are sentient (biopsychism); (ii) there is a strong analogy between the phloem transport system of plants and the nervous system of animals; and (iii) plants are the cognitive equals of sentient animals. On the basis of a model of consciousness that spells out criteria for assigning (...) sentience to a living organism and presents a diagnostic evolutionary marker of consciousness, we argue that these arguments are flawed and discuss some of the ethical issues they raise.

In Delusions of consciousness, Blackmore supports illusionism on consciousness, using a Humean approach toward "self." First, she tries to explain away the intuitive, realistic viewpoint on self-consciousness; she "explains why some the illusionary self-consciousness is so compelling" by claiming a "simple mistake in introspections" and tries to explain it away. Secondly, she concludes that the idea of illusionary self-consciousness shows the delusion of consciousness per se. In this paper, first, I shall show that her explanation against realism on consciousness (in (...) support of the illusion of self-consciousness) is not decisive; it can be formulated such that works against illusionism. Secondly, I show that un-consciousness is a delusion and explain it away, not in a Humean approach, but in terms of the semantics of "forgetfulness." Thirdly, I shall show that Blackmore wrongly concludes delusion of consciousness, on the basis of illusionary self-consciousness, while the latter doesn't necessarily entail the former. (shrink)

Uncovering the neural basis of consciousness is a major challenge to neuroscience. In this Perspective, Tononi and colleagues describe the integrated information theory of consciousness and how it might be used to answer outstanding questions about the nature of consciousness.

Predictive Processing theory, hotly debated in neuroscience, psychology and philosophy, promises to explain a number of perceptual and cognitive phenomena in a simple and elegant manner. In some of its versions, the theory is ambitiously advertised as a new theory of conscious perception. The task of this paper is to assess whether this claim is realistic. We will be arguing that the Predictive Processing theory cannot explain the transition from unconscious to conscious perception in its proprietary terms. The explanations offer (...) by PP theorists mostly concern the preconditions of conscious perception, leaving the genuine material substrate of consciousness untouched. (shrink)

This study advances a refutation of Physicalism. It demonstrates that it cannot, coherently, be maintained. An alternative approach based on Husserl’s ‘transcendental ego’ is developed. This is an account where the physical world is constituted by a freely acting self from a phenomenology that is ontologically neutral. By doing so, the, so-called, ‘hard problem’ of consciousness is dissolved. It will be shown that the self is compelled to attribute moral and aesthetic value to the world that it has constituted. The (...) determinism that Physicalism engenders is shown to lead to a nihilism that makes all knowledge impossible. Genuine personal responsibility for action, is asserted within strict limits. A position is outlined that gives a role to the self in causation and one that entails the possibility of panpsychism. (shrink)

The main topic of this paper is the mind-body problem. The author analyzes it in the context of Hus- serlian phenomenology. The key texts for the analysis and interpretation are Descartes’ magnum opus “Meditations on the First Philosophy” and Husserl’ last work “The Crisis of European Sciences and Transcendental Phenomenology”. The author claims that already in Descartes’ text instead of one mind-body problem, one can find two: the ontological mind-body problem (mind-brain relation) and conceptual one (“mind” and “body” as concepts). (...) In Descartes’ “Meditations”, the ontological level is explicit, while the conceptual level is implicit. In Husserl’s “Crisis”, on the other hand, the situation is different: the conceptual level of the problem (as the opposition between transcendental phenomenology and natural sciences) is explicit, while the ontological level is implicit. Nevertheless, it seems that Husserl has answers to both the “traditional” as well as the “conceptual” mind-body problems. (shrink)

In this paper, I attempt to clarify the heart of Dewey’s philosophy: his method (denotative method (DM) / pattern of inquiry (PI)). Despite the traditional understanding of Dewey as anti-foundationalist, I want to show that Dewey did have metaphysical foundations for his method: the principle of continuity or theory of emergentism. I also argue that Dewey’s metaphysical position is better named as ‘cultural emergentism’, rather than his own term ‘cultural naturalism’. What Dewey called ‘common sense’ in his Logic, Husserl termed (...) as the ‘life-world’ in his Crisis. I compare two perspectives of dealing with the phenomenon and conclude that for Dewey, the difference between natural sciences and the common sense inquiry is that of subject-matter but not of method. Thus, the goal is to find the unified method to be applied in both domains. Whereas Husserl was more pessimistic: for him, the difference was not only in subject-matter, but in the very methods. Following that discussion, I also attempt to reformulate the hard problem of consciousness in Deweyan terms. In the end, I compare Dewey’s DM / PI with Popper’s understandings of scientific method and conclude that there is no significant difference between the two and that Dewey’s method could also be looked at as hypothetic-deductive method, with the only difference in emphases.

This paper explores the problematic issue of the theoretical dominance of neuroscience in the discipline of consciousness studies and tries to explain why such a dominance must not be encouraged through the philosophical and logical divulgement of the methodological shortcomings of neuroscience in explaining consciousness. Besides this, the paper also reminds us of the utmost and exclusive importance of 'consciousness' in consciousness studies and rivets our attention to the immense importance of adopting a multidisciplinary ecumenic approach towards understanding consciousness.

When physical structures resonate in proximity to each other they will under certain circumstances 'sync up' in a shared resonance frequency. This is the phenomenon of spontaneous selforganization. General resonance theory (GRT), a theory of consciousness developed by Hunt and Schooler, suggests that consciousness is a product of various shared resonance frequencies at different physical scales. I suggest a heuristic for calculating the boundaries and resulting capacity for phenomenal consciousness in such resonating structures. Shared resonance results in phase transitions in (...) the speed and bandwidth of information exchange and thus richer and more complex consciousness. This approach is a solution to the 'combination problem' and 'boundary problem' of consciousness. The proposed mathematical heuristic is a practical approach for identifying potential conscious structures and the spatial and temporal boundaries of such structures over time, and also for calculating the capacity for phenomenal consciousness of any putative conscious entity. The slowest-frequency shared resonance -- the 'slowest common denominator'-- is the limiting factor for the spatial extent of any macro-consciousness. Various synchrony indexes are discussed. I describe some limitations of the proposed framework, and how it compares to Tononi's integrated information theory. IIT's constellation- qualia characterization framework is compatible with GRT and may be a useful tool in conjunction with GRT's quantification framework. (shrink)

It is proposed that a human conscious experience of the sort we report to each other reflects a direct causal interaction between a pattern of information about the world, encoded in a field of postsynaptic potentials, and a quantized mode of excitation occupying dendritic cytoskeleton. The requirement for a quantized account is seen simply as the need for an event of experience to be a single indivisible, but richly patterned, causal relation between information and an 'informee'. It is argued that (...) the informee is likely to be a higher-order quantized collective mode (much as proposed by Craddock and colleagues, 2017) with the biologically relevant dynamics likely also to be describable in classical terms. No specific interpretation of quantum theory is needed. In this scenario, anaesthetics would abrogate reportable experience by detuning parameters underpinning cytoskeletal informee modes, perhaps critically increasing associated impedence. It is also proposed that tuning and detuning of informee modes in individual dendritic trees by binding of accessory proteins to cytoskeleton plays a physiological role in short-term memory and truth evaluation through ascertainment of sequential signal pattern consonance. Components of this model may be involved in cellular adaptive responses in many types of organism. (shrink)

Higher-order theories of consciousness come in many varieties, but all adopt the 'transitivity principle' as a central, explanatory premise. The transitivity principle states that a mental state of a subject is conscious if and only if the subject is aware of it. This higher-order awareness is realized in different ways in different forms of higher-order theory. I argue that empirical studies of metacognition have falsified the transitivity principle by showing that there can be awareness of a mental state without that (...) state's becoming conscious. I present two such studies in detail and argue that the measures they employ cannot be interpreted in a way that would make the results compatible with higher-order theory. Since all versions of the theory rely on the transitivity principle, this entails that all forms of higher-order theory are false. (shrink)

Overgaard and Kirkeby-Hinrup conclude their comment on our Opinion article by asking, ‘Does SOMA entail that animals, children and many adults are not conscious?’ This question is indeed essential, and our answer is a clear: ‘We do not know, nor does anyone else.’ But we want to state right away that we believe they are. In this respect, Overgaard and Kirkeby-Hinrup’s core critique is misguided. We need to carefully distinguish between ethical and scientific considerations. Scientific claims are based on what (...) we think is the case, whereas ethical considerations are based on what we think ought to be the case. Thus, one might think that infants lack consciousness yet choose to act toward them as though they were. Hinduism considers that all living things are sacred and should not be harmed ( ahimsa). Jainists go further and will wear masks to avoid accidentally breathing in insects. Such beliefs and practices are independent of our scientific knowledge. Although one may wish that our ethics be informed by science, the former is independent of the latter and should in no way be subsidiary to it. Appealing to ethical considerations to rebut scientific claims is rhetorically unsound. (shrink)

The contemporary debate around consciousness presents us (and often leads us to embrace) a specific current of thought: physicalism, which states that everything in our reality is physical1. In this paper I want to introduce the main points of the opposite view, dualism, according to which there are two different realms of reality: the mental and the physical one. In the introduction I give the main idea and sketch the general intuition behind dualism. In Section 1 I present substance dualism (...) and its more refined version, which is interactionism. In sub-section 1.1 I describe property dualism, which is the mainstream form of dualism adopted nowadays. In sub-sections 1.1.2 and 1.1.3 are proposed two variations of property dualism: epiphenomenalism and panpsychism. Finally, in Section 2 and its two sub-sections (2.1 and 2.2.) I recall Frank Jackson’s famous 1982 thought experiment and two classical objections to it, which are the Ability Hypothesis and the phenomenal concept strategy one. I conclude with a short reflection if we were to take under consideration the acceptance of dualism as an explanation of consciousness and its nature. PS: there's a mistake at page 12, as there's a note in the middle of the page that is not supposed to be there. (shrink)

Not only does Hoffman claim that we do not see reality as it is, but that unperceived brains, trees and moons do not exist. His “interface theory of perception” is a peculiar blend of metaphorical ontology (objects are icons, space-time is a desktop) and mathematical modelling (the game-theoretical argument that fitness trumps truth. Conflating abstractions with concrete experience, evolution is used to refute everything (including evolution itself. Hoffman’s sweeping iconoclasm then lands where it took off: addressing the problem of consciousness. (...) After arguing against reality, he will tell us what it is. (shrink)

I begin by developing a challenge for the Higher-Order Thought variant of Higher-Order representational theories of consciousness. The challenge is to account for the distinctive phenomenal character of visual experience—its presentational character. After setting out the challenge, I articulate a novel form of Higher-Order theory that can account for presentational character: the Map Theory of consciousness. The theory’s distinctive claim is that the relevant higher-order representations have a cartographic format.

We suggest a teleological approach to subjective experiencing or phenomenal consciousness. Like living, subjective experiencing is a teleology-constituting mode of being, which is made up of coupled, functional processes. We explicate our notion of a 'teleological mode of being' and distinguish between three different modes: a living (non-sentient) mode of being, a sentient mode of being, and a rational-symbolic (human) mode of being, which correspond to the three levels of soul suggested by Aristotle. These evolved teleological modes of being are (...) characterized by the possession of distinct, hierarchically nested goals and value systems. We argue that the functions of parts and processes within living systems have to be situated within the appropriate teleological frame of reference. Our evolutionary and comparative approach to the mode of being of subjectively experiencing animals clarifies why functions are best attributed to the parts that constitute sentience. Our proposal resolves the problem of attributing functions to phenomenal consciousness, resonates with basic teleological intuitions and distinctions, and corresponds to the modern broad understanding of selection and evolution.

This article discusses two arguments against the integrated information theory (IIT) of consciousness. The first argument says that IIT is wrong in saying that conscious experiences are identical to conceptual structures; they are very different in many ways. The second argument says that the seeming presence of non-conscious integrated information either makes IIT falsified or unfalsifiable. The first argument seeks to show that integrated information is not identical to consciousness; the second argument seeks to show that integrated information is not (...) even always correlated with consciousness.

An abundant literature on autism shows differences in emotional consciousness between neurotypical and autistic people. This paper proposes an interpretation of these results through a conceptual clarification of emotional consciousness. It suggests that autistic people generally access their emotions through a thirdperson's perspective whereas neurotypical people's emotions reach consciousness via first-person access. This interpretation is based on a model of 'emotional consciousness' that applies leading theories of consciousness to emotions as well as on research on the way autistic people relate (...) to their own emotions. This model differentiates two routes through which emotions can access consciousness. Therefore, research on emotions in autism helps to give a more complete account for emotional consciousness in general. (shrink)

Integrated Information Theory posits a new kind of information, which, given certain constraints, constitutes consciousness. Searle objects to IIT because its appeal to information relies on observer-relative features. This misses the point that IIT’s notion of integrated information is intrinsic, the opposite of observer-relative. Moreover, Searle overlooks the possibility that IIT could be embraced as an extension of his theory. While he insists that causal powers of the brain account for consciousness, he maintains that these causal powers aren’t tied to (...) protoplasmic material. Whatever these causal powers are, they don’t consist in mere information-processing or computation. IIT agrees, and also positively characterizes the relevant causal powers as those involved in generating integrated information. Examining the further commitments of each theory reveals that IIT renews a fundamentally ontological challenge to information-processing and computational theories of mind. (shrink)

Conceivability arguments constitute a serious threat against reductive physicalism. Recently, a number of authors have proven and characterized a devastating logical truth, centered on these arguments: namely, that their soundness entails the inconceivability of reductive physicalism. In this paper, I demonstrate that is only a logical truth when reductive physicalism is interpreted in its stronger, intrinsic sense, as opposed to its weaker—yet considerably more popular—extrinsic sense. The basic idea generalizes: perhaps surprisingly, stronger forms of reduction are uniquely resistant to the (...) conceivability arguments opposing them. So far as the modal epistemology of reduction is concerned, therefore, it pays to go intrinsic. (shrink)

In defining physical (i.e. causal dynamic) units to which conscious experience is to be ascribed, integrated information theory (IIT) raises three notable requirements: (1) that a unit to which consciousness is ascribed must be defined, or circumscribed, by some intrinsic aspect or property, where intrinsic implies existing 'for itself' or 'from its point of view'; (2) that the intrinsic aspect that defines the unit to which consciousness is ascribed must be dynamic (i.e. involve causal power) rather than purely structural or (...) kinematic; (3) that this dynamic aspect must involve the integration of elements of information in such a way that semantic values of elements are interdependent, allowing rich meaning. It will be argued that, although these requirements are all well-motivated, IIT falls short on them within a testable natural science framework. Concerns raised about the three requirements all point towards one central problem: that the concept of 'integrated information' does not involve any specific causal relation. Although IIT starts from strictly causal premises, the final analysis appears to invoke two incompatible accounts of the same events, with 'integration' having no causal relational basis. It will also be argued that the way IIT attempts to provide a testable theory of dynamic units to which consciousness is ascribed mustcausal reason inherent in any means of testing, be at best redundant for in the human case and, as a general principle, untenable.

This paper reviews and discusses empirical evidence from consciousness research, especially research into anomalies, and asks the question what, if taken seriously, would those data mean for our concepts of consciousness, science, and religion. It shows that the process of naturalization, i.e. finding scientific explanations for as yet badly understood phenomena, is not finished yet and could have a profound impact both on science and religion: traditional religious concepts would have to be reconsidered, and the scientistic materialist worldview that is (...) currently implicitly underpinning much of science would prove to be untenable. The empirical evidence, if accepted, demands a concept of consciousness that grants consciousness some fundamental status in the world, and the capacity to non-locally connect to events and other consciousnesses. This would seem to preclude a materialist concept of science, as well as some fundamentalist concepts of religion. It would continue the process of naturalizing religion into some as yet uncharted territory. (shrink)

'Thick neural event' is introduced to mean an event that requires firings of more than one neuron and a substantive (i.e. additional to merely temporal and spatial) relation among them. It is shown that some well regarded theories (e.g. by Lamme, Koch, etc.) strongly suggest that neural correlates of consciousness (NCCs) are thick neural events. It is then shown that thin (= not thick) neural events provide sufficient causation for neural events leading to behaviour, and that there are good reasons (...) to reject overdetermination by thick events. Thus, any physicalism that recognizes legitimacy of a search for NCCs must either reject theories that embrace thickness of NCCs, or accept the epiphenomenalistic view that the properties in virtue of which we are conscious are not properties in virtue of which events causally contribute to our behaviour.

The meta-problem of consciousness is to explain why we think that there is a hard problem of consciousness. On Chalmers' view of the meta-problem, our judgments about the hard problem of consciousness arise non-inferentially as a result of introspection. I raise two problems for such a non-inferentialist view of the metaproblem. It does not seem to match the psychological facts about how we come to the realization of the hard problem, and it is unclear how the view can bridge the (...) gap between the content of introspection and the content involved in formulations of the hard problem. The inferentialist view of the meta-problem, on which the hard problem results from inference, explains both the psychology and content introduction. We should therefore prefer an inferentialist view of the meta-problem. (shrink)

Why is there a 'hard problem' of consciousness? Why do we seem unable to grasp intuitively that physical brain processes can be identical to experiences? Here I comment on the 'meta-problem' (Chalmers, 2018), based on previous ideas (Storm, 2014; 2018). In short: humans may be 'inborn dualists' ('neuroscepticism'), because evolution gave us two (types of) brain systems (or functional modes): one (Sp) for understanding relatively simple physical phenomena, and another (Sm) specialized for mental phenomena. Because Sp cannot deal with the (...) immense complexity of the brain processes underlying consciousness, it represents them as fundamentally different from nonmental physical phenomena (dualist intuition), using 'simulations' to produce 'Sm-type understanding'/predictions that seems radically different from 'Sp-type understanding'. (By analogy, different sensory modalities, handled by distinct brain systems, evoke qualitatively different experiences.) Brain systems for Sp representations of our brain processes never evolved, because they would be useless. When lacking a single 'template' matching different aspects of reality (objective vs. subjective = simulated), complementary 'models' are needed ('neuro-complementarity'), like the wave–particle duality in quantum mechanics. Thus, it seems plausible that Sp and Sm evolved because they were needed to cope with different challenges, and that 'problem intuitions' are side effects of these useful but different brain systems. (shrink)

I argue that there is a version of (quasi-Armstrongian) weak illusionism that intelligibly relates phenomenal concepts and introspective opacity, accounts for the (hard) problem intuitions Chalmers highlights (modal, epistemic, explanatory, and metaphysical), and undermines the most important arguments Chalmers deploys against type-B and type-C materialisms. If this is successful, we can satisfactorily account for the meta-problem of consciousness, mollify our hard problem intuitions, and remain genuine realists about phenomenal experience.

Solving the meta-problem of consciousness requires, among other things, explaining why we are so reluctant to endorse various forms of illusionism about the phenomenal. I will try to tackle this task in two steps. The first consists in clarifying how the concept of consciousness precludes the possibility of any distinction between 'appearance' and 'reality'. The second consists in spelling out our reasons for recognizing the existence of something that satisfies that concept.

The meta-problem of consciousness is the problem of explaining why we have the intuition that there is a hard problem of consciousness. David Chalmers briefly notes that my phenomenal powers view may be able to answer to this challenge in a way that avoids problems (having to do with avoiding coincidence) facing other realist views. In this response, I will briefly outline the phenomenal powers view and my main arguments for it and—drawing in part on a similar view developed by (...)

Chalmers' (2018) meta-problem of consciousness emphasizes unexpected common ground between otherwise incompatible positions. We argue that the materialist should welcome discussion of the meta-problem. We suggest that the core of the metaproblem is the seeming arbitrariness of subjective experience. This has an unexpected resolution when one moves to an interventionist account of scientific explanation: the same interventions that resolve the hard problem should also resolve the meta-problem.

Chalmers (2018) raises three challenges for Michael Graziano's attention schema theory. Our aim in this paper is to bolster Graziano's attention schema theory with some tools and insights from the predictive processing framework, in order to respond to the challenges raised by Chalmers and more generally strengthen the theory. We will first introduce the attention schema theory and the three challenges raised by Chalmers, before outlining our application of predictive processing to the theory and how it can resolve these challenges, (...) thus offering a solution to the meta-problem.

The hard problem of consciousness is about how we could explain in physicalist terms why we are conscious. The meta-problem of consciousness is about how we could explain why we have a hard problem of consciousness. In this note I argue that the phenomenal concept strategy can in principle provide a satisfactory solution to the meta-problem.

I present two caveats to the meta-problem challenge to theories of consciousness. Chalmers suggests that a theory of consciousness that solves the hard problem should also inform us about the meta-problem, and vice versa. The first caveat is the view that mechanism M, the mechanism through which content becomes conscious, may be neutral with respect to the content it renders conscious. This means that there can be no systematic connection between M and conscious content. The second caveat concerns how we (...) should treat the problem intuitions fueling the meta-problem. I argue that we should award them no special status with respect to their explanatory power in relation to the hard problem. (shrink)
