Theories of Consciousness

Identifying the physiological processes in the central nervous system that underlie our conscious experiences has been at the forefront of cognitive neuroscience. While the principles of classical physics were long found to be unaccommodating for a causally effective consciousness, the inherent indeterminism of quantum physics, together with its characteristic dichotomy between quantum states and quantum observables, provides a fertile ground for the physical modeling of consciousness. Here, we utilize the Schrödinger equation, together with the Planck-Einstein relation between energy and frequency, (...) in order to determine the appropriate quantum dynamical timescale of conscious processes. Furthermore, with the help of a simple two-qubit toy model we illustrate the importance of non-zero interaction Hamiltonian for the generation of quantum entanglement and manifestation of observable correlations between different measurement outcomes. Employing a quantitative measure of entanglement based on Schmidt decomposition, we show that quantum evolution governed only by internal Hamiltonians for the individual quantum subsystems preserves quantum coherence of separable initial quantum states, but eliminates the possibility of any interaction and quantum entanglement. The presence of non-zero interaction Hamiltonian, however, allows for decoherence of the individual quantum subsystems along with their mutual interaction and quantum entanglement. The presented results show that quantum coherence of individual subsystems cannot be used for cognitive binding because it is a physical mechanism that leads to separability and non-interaction. In contrast, quantum interactions with their associated decoherence of individual subsystems are instrumental for dynamical changes in the quantum entanglement of the composite quantum state vector and manifested correlations of different observable outcomes. Thus, fast decoherence timescales could assist cognitive binding through quantum entanglement across extensive neural networks in the brain cortex. (shrink)

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.

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)

Carruthers has recently argued for a surprising conditional: if a global workspace theory of phenomenal consciousness is both correct and fully reductive, then there are no substantive facts to discover about phenomenal consciousness in non-human animals. I present two problems for this conditional. First, it rests on an odd double-standard about the ordinary concept of phenomenal consciousness: its intuitive non-gradability is taken to be unchallengeable by future scientific developments, whereas its intuitive determinacy is predicted to fall by the wayside. Second, (...) it relies on dismissing, prematurely, the live empirical possibility that phenomenal consciousness may be linked to a core global broadcast mechanism that is (determinately) shared by a wide range of animals. Future developments in the science of consciousness may lead us to reconsider the non-gradability of phenomenal consciousness, but they are unlikely to lead us to accept that there are no facts to discover outside the paradigm case of a healthy adult human.

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)

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)

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.

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)

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.

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)

It is most likely for anyone to ask himself at least once if it would be possible to live in a dream? Questioning the fabric of “reality” we live in consciously was one of the main doubts man ever had. It is so likely for us to answer positively to it due to so many factors; starting from the many and various facets of reality each individual envision the world, from the enormous differences we all have while perceiving and defining (...) the reality, etc. That is why, at the conscious level, life seems almost like a dream in a dream, always hoping to wake up from the negative, unwanted version of it. That is why my assertion here, based on latest theories on consciousness and AI, aim to say that we live in between reality and dream, being “conscious” of ourselves, but not really wanting to be “aware” of what is really going on with us. Living as a human is not a path towards improvement in the way of getting rid of subjectiveness and valorization because these so-called errors make the most of human living. (shrink)

The subjective features of psychological phenomena have been studied intensively in experimental science in recent years. Although various methods have been proposed to identify subjective features of psychological phenomena, there are elusive subjective features such as the spatiotemporal structure of experience, which are difficult to capture without some additional methodological tools. We propose a new experimental method to address this challenge, which we call the contrast-based experimental phenomenological method (CEP). CEP proceeds in four steps: (i) front-loading phenomenology, (ii) online second-personal (...) interview, (iii) questionnaire survey, and (iv) hypotheses testing. It differs from other experimental phenomenological methods in that it takes advantage of phenomenal contrasts in collecting phenomenological data. In this paper, we verify the validity and productivity of this method by applying it to binocular rivalry (BR). The study contributes to empirical research on BR in three respects. First, it provides additional evidence for existing propositions about the subjective features of BR: e.g. the proposition that the temporal dynamics of the experience depend upon subject-dependent parameters such as attentional change. Second, it deepens our understanding of the spatiotemporal structures of the transition phase of BR. Third, it elicits new research questions about depth experience and individual differences in BR. The presence of such contributions demonstrates the validity and productivity of CEP. (shrink)

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)

Can information theory be used to understand neural signaling? Yes, but assumptions have to be made about the nature of that signaling. The traditional view is that the individual neural spike is an all-or-none phenomenon, which allows neural spikes to be viewed as discrete, binary pulses, similar in kind to the signals in digital computers. Under this assumption, the tools of information theory can be used to derive results about the properties of neural signals. However, new results from neuroscience demonstrate (...) that the precise shape of the individual spike can be functionally significant, thus violating the assumption that spikes can always be treated as a binary pulse. Instead, spikes must sometimes be viewed as a continuous signal. Fortunately, information-theoretic tools exist for the study of continuous signals; unfortunately, their use in the continuous domain is very different from their use in the discrete domain, and not always well understood. Researchers interested in making precise claims about the nature of the information used, stored, and processed in neural systems must pay careful attention to these differences. (shrink)

Peter Carruthers argues that the global workspace theory implies there are no facts of the matter about animal consciousness. The argument is easily extended to other cognitive theories of consciousness, posing a general problem for consciousness studies. But the argument proves too much, for it also implies that there are no facts of the matter about human consciousness. A key assumption of the argument is that scientific theories of consciousness must explain away the explanatory gap. I criticize this assumption and (...) point to an alternative strategy for defending scientific theories of consciousness, one that better reflects the ongoing scientific practice. I argue there are introspectable inferential connections from phenomenal concepts to functional concepts that scientists can use to individuate the global workspace in terms of capacities that animals and humans share. (shrink)

Scientists disagree about which capacities a functional analysis of consciousness should target. To address this disagreement, I propose that a good functional analysis should target the etiological functions of consciousness. The trouble is that most hypotheses about the etiological origins of consciousness presuppose particular functional analyses. In recent years, however, a small number of scientists have begun to offer evolutionary hypotheses that are relatively theory neutral. I argue that their hypotheses can serve an independent standard for evaluating among theories of (...) consciousness. (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.

Emotions and feelings affect economic systems. This is well known as e.g. stock markets tend to react to sudden political and emotional events. However, the link between emotions, consciousness, and economic systems at a deeper level than the aggregate resulting action of people at large is yet to be explored and understood. In this paper, a first building block is presented as it is shown that a variable derived from the random numbers obtained by the Global Consciousness Project is statistically (...) related to various well-known stock market index returns. The relationship is shown to be non-linear and that variations in the variable, to some extent, predate the underlying trade. The results presented are found to be robust and qualitatively unaffected by the removal of outliers. Apart from the pure economic value of these findings, the results have truly baffling implications. This is the case as they confirm some previous unorthodox research suggesting that consciousness stretches out beyond the locally confined space of our heads and that consciousness can affect hardwaregenerated random numbers at a distance. Thus, these results put doubt on the existing paradigm with regards to consciousness and highlight the need for further research. (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.

A mechanism for life after death is given.

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)

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.

Chalmers (2018) considers a wide range of possible responses to the meta-problem of consciousness. Among them is the ignorance hypothesis -- the view that there only appears to be a hard problem because of our inadequate conception of the physical. Although Chalmers quickly dismisses this view, I argue that it has much greater promise than he recognizes. The plausibility of the ignorance hypothesis depends on how exactly one frames the 'problem intuitions' that a solution to the meta-problem must explain. I (...) argue that problem intuitions are hybrid intuitions that encompass one's intuitive take on the phenomenal and one's intuitive take on the physical. The ignorance hypothesis undermines the second half of these hybrid intuitions. I show how the ignorance hypothesis is preferable to the alternatives and attempt to explain why there is such widespread resistance to this promising position. (shrink)

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 (...) Harold Langsam—discuss how more precisely its answer to the challenge would go. (shrink)

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. (shrink)

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)

The meta-problem of consciousness is the problem of explaining why we have problem intuitions about consciousness, why we intuitively think that conscious experience cannot be scientifically explained. In his discussion of this problem, David Chalmers briefly considers the possibility of giving a 'genealogical' solution, according to which problem intuitions are 'accidents of cultural history' (2018, p. 33). Chalmers' response to this solution is largely dismissive. In this paper, we defend the viability of a genealogical solution. Our strategy is to focus (...) on a particular problem intuition: the thought that the phenomenal character of colour experience is irreducibly subjective. We use the history of the inverted spectrum thought experiment as a window into how various philosophers have thought about colour experience. Our genealogy reveals that problem intuitions about colour are not timeless, but instead arise in a specific historical context, one that, in large part, explains why we have these intuitions. (shrink)

The meta-problem of consciousness is framed as a route into investigating why there are problems in understanding consciousness by describing the mechanisms underpinning our tendency to describe consciousness as problematic, and the evolutionary origins of these mechanisms. This is framed as a means of uniting illusionists and realists toward a common goal, but this supposes that the only viable form of illusionism is what I call 'hard-wired' illusionism, under which phenomenal judgments are a direct product of natural selection. I argue (...) that, instead, 'soft-wired' illusionism is more plausible, where phenomenal judgments are seen to be cultural phenomena. Since the problem of consciousness arises from a flawed theory of consciousness, pointing out the mechanisms underlying expression of the theory and the historical origins of the theory will not suffice to tell us why the theory is problematic. As such, the meta-problem is exclusionary toward soft-wired illusionism. (shrink)

Information and meanings are present everywhere around us and within ourselves. Specific studies have been implemented in order to link information and meaning (Linguistic, Semiotic, Biosemiotic, Psychology, Psychiatry, Biology, Neurology, Cognition, Artificial Intelligence... ). No general coverage is available for the notion of meaning. We propose to complement this lack by a system approach for meaning genaration. A Meaning Generator System based on constraint satisfaction is presented. It can be used for animals, humans and artificial agents, and makes available definitions (...) for agency and autonomy. Usage of the MGS with the Turing Test shows why today computers cannot think like humans do. The MGS introduces evolutionary scenarios for cognition, intentionality and self-consciousness where a specific human anxiety is highlighted. Anxiety limitation is then a key human constraint tightly related to an evolutionary nature of self-consciousness. That new perspective positions mostly unconscious anxiety management processes as driving human mental states and conditioning our mental health, much more than assumed so far. Continuations are proposed. (shrink)

I argue that our direct experience and some physical facts do not go well with an understanding of perception as a mechanism producing a representation of a ''truly'' outer world. Instead, it is much more coherent to treat what is traditionally considered an image in this context as a closed structure equipped in its own ontology, replacing the ''truly'' outer one from the point of view of an agent possessing it. In such a framework, the notion of existence is taken (...) to be defined by consciousness in a way similar to qualia, making it subjective on the one hand, and reducing it to a tool on the other. This implies, in turn, that we need a form of mind-brain dualism; the best we can do in such circumstances about explaining consciousness as an epistemic device - a role intuitively imposing itself in a variety of situations - is to embed it in an abstract ontology merely serving the purpose of a ''true'' reality with the help of the mind-brain link. Obviously, the approach favors subjectivity as a foundation in the ontological sense. Objectivity is considered here only as a suitably understood product from an ''observer's'' point of view, although a functional and useful one. The paper is addressed to readers with interest in both the mind-body problem and ontological foundations of present-day physics, specifically quantum theory. The main conclusion can be absorbed without the quantum part, although it is a bit less convincing then. (shrink)

Consciousness is widely perceived as a phenomenon that poses a special explanatory problem for science. The problem arises from the apparent rift between immediate first-person acquaintance with consciousness and our inability to provide an objective/scientific third-person characterization of consciousness. In this paper, I outline a theory of perceptual consciousness called the 'Quantum Uncertainty Reduction (QUR)1 Theory of Access and Phenomenal Consciousness'. The theory offers a functional solution to the hard problem of consciousness in terms of quantum information processing in a (...) Bayesian brain-inspired information processing system. I argue that the central aspect/step of information processing, namely, quantum uncertainty reduction, gives rise to qualitative properties of phenomenal and access consciousness. (shrink)

What is it like to be an octopus, one of those eight-armed, infinitely flexible sea creatures with a nervous system distributed over head, eyes and arms? One interesting approach is to argue that octopuses, because of their distributed nervous systems, are likely to possess disunified consciousness (Carls-Diamante 2017). However, this supposed isomorphism between a “unified” nervous system and “unified” consciousness is problematic, since the term “unity” is taken as a “given” even though it is far from clear what it means. (...) I will argue that explaining the structure of consciousness requires a prior explanation in terms of how it is achieved by the organism through sensorimotor integration. On this account, the structure of an organism’s consciousness is explained partly by what the external world is like, and partly by how the organism’s body, senses and nervous system enable the organism to interact with the external world.
