Daniel Dennett (1996) has disputed David Chalmers' (1995) assertion that there is a "hard problem of consciousness" worth solving in the philosophy of mind. In this paper I defend Chalmers against Dennett on this point: I argue that there is a hard problem of consciousness, that it is distinct in kind from the so-called easy problems, and that it is vital for the sake of honest and productive research in the cognitive sciences to be clear about (...) the difference. But I have my own rebuke for Chalmers on the point of explanation. Chalmers (1995, 1996) proposes to "solve" the hard problem of consciousness by positing qualia as fundamental features of the universe, alongside such ontological basics as mass and space-time. But this is an inadequate solution: to posit, I will urge, is not to explain. To bolster this view, I borrow from an account of explanation by which it must provide "epistemic satisfaction" to be considered successful (Rowlands, 2001; Campbell, 2009), and show that Chalmers' proposal fails on this account. I conclude that research in the science of consciousness cannot move forward without greater conceptual clarity in the field. (shrink)

OPINION IS DIVIDED as to whether the "qualitative characters" or "qualia" of conscious sensory experiences such as color perceptions and pain sensations genuinely constitute a major obstacle to the success or tenability of contemporary physicalist theories of mind. Do the enormous complexities of human brain activity--conceived more or less as we now conceive it--alone suffice to account for our conscious sensory experiences, and thereby show how the experiences are nothing over and above the brain activities, or must there be some (...) further kind of thing, if we are to account for the existence of our kind of consciousness? This issue, representing perhaps the most profound division of opinion in contemporary philosophy of mind, cannot possibly reach a genuine resolution in the absence of a satisfactory answer to a question which has suffered astonishing neglect in the extensive debate on this issue: What exactly is the qualitative character of a conscious sensory experience? What exactly is it about color perception, for example, that makes it so distinctive in a "qualitative" respect, allegedly making trouble for contemporary theories of mind? (shrink)

I argue for an idealist ontology consistent with empirical observations, which seeks to explain the facts of nature more parsimoniously than physicalism and bottom-up panpsychism. This ontology also attempts to offer more explanatory power than both physicalism and bottom-up panpsychism, in that it does not fall prey to either the ‘hard problem of consciousness’ or the ‘subject combination problem’, respectively. It can be summarized as follows: spatially unbound consciousness is posited to be nature’s sole ontological primitive. We, (...) as well as all other living organisms, are dissociated alters of this unbound consciousness. The universe we see around us is the extrinsic appearance of phenomenality surrounding—but dissociated from—our alter. The living organisms we share the world with are the extrinsic appearances of other dissociated alters. As such, the challenge to artificially create individualized consciousness becomes synonymous with the challenge to artificially induce abiogenesis. (shrink)

One of the persistent debates that has animated thinkers concerns the nature of consciousness. Is it merely an epiphenomenon that can be reduced to matter or does it belong to a different ontological domain? In recent times, this question has been reformulated as the hard problem of how material brain states can give rise to the mental states that we seem to experience. One of the answers to the hard problem has been to deflate the question (...) and simply deny that there is a problem. This chapter argues that this approach often associated with Dennett and embraced by Siderits is problematic within the framework of Buddhist philosophy given the latter’s strong insistence on observing how things appear to the mind. This essay further argues that Buddhism offers resources to deal with the hard problem through the Madhyamaka philosophy, which argues that it does not make sense to think how things are and that we should be content to deal with how things appear. In this perspective, the task of explaining consciousness is neither to eliminate appearances à la Dennett nor to discover what the mind really is in itself, but to learn how to correlate better the various appearances though which the mental is given (the first and third person perspectives). In this way, the hard problem ceases to be a mystery and becomes an object of scientific inquiry that relies on the ever tighter observation of the neuro-phenomenological correlation between first and third person perspectives.

This thesis articulates an analytic version of the ontology of idealism, according to which universal phenomenal consciousness is all there ultimately is, everything else in nature being reducible to patterns of excitation of this consciousness. The thesis’ key challenge is to explain how the seemingly distinct conscious inner lives of different subjects—such as you and me—can arise within this fundamentally unitary phenomenal field. Along the way, a variety of other challenges are addressed, such as: how we can reconcile idealism with (...) the fact that we all inhabit a common external world; why this world unfolds independently of our personal volition or imagination; why there are such tight correlations between measured patterns of brain activity and reports of experience; etc. The core idea of this thesis can be summarized thus: we, as well as all other living organisms, are dissociated alters of universal phenomenal consciousness, analogously to how a person with Dissociative Identity Disorder (DID) manifests multiple disjoint centers of subjectivity also called ‘alters.’ We, and all other living organisms, are surrounded by the transpersonal phenomenal activity of universal consciousness, which unfolds beyond the dissociative boundary of our respective alter. The inanimate world we perceive around us is the extrinsic appearance—i.e. the phenomenal image imprinted from across our dissociative boundary—of this activity. The living organisms we share the world with are the extrinsic appearances of other alters. (shrink)

Qualitative states are no threat to physicalism. They have a causal effect upon the world in virtue of their qualitative nature. This effect is exploited in biological mechanisms for representing the world. Representation requires differential responsiveness to different perceived properties of things. Qualia are taken to be tagged properties of internal representation models. These properties are properties for-the-organism. Such for-the-organism properties are to be expected in beings which perceive the world and interact with it intelligently. Consciousness presents a problem (...) for science. Human beings are conscious of the world and of themselves. In so far as science has the ambition of explaining everything consciousness is another unexplained phenomenon. However some claim that it is distinctive and different in kind from other problems which science hopes to solve using methods which have been successful up until now. It may indeed be so different that we have to adopt a dualistic metaphysics and accept that there is more to the world than physics knows. In this paper I intend to outline how the physicalist should fight back. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:How Things Are: An Introduction to Buddhist Metaphysics by Mark SideritsRick Repetti (bio)How Things Are: An Introduction to Buddhist Metaphysics. By Mark Siderits. Oxford, UK: Oxford University Press, 2022. Pp. vi + 204. Paperback $29.95, ISBN 978-0-19-760691-9.How Things Are: An Introduction to Buddhist Metaphysics, by Mark Siderits, presents ten chapters on Buddhist metaphysics that will appeal to readers from any number of backgrounds, e.g. Western philosophers concerned with (...) analytic metaphysics, but also philosophers of mind, epistemologists, phenomenologists, philosophers of meditation, comparative philosophers, non-Buddhist Indian philosophers, and Buddhist philosophers. The book includes an introductory chapter and chapters on the self, the person, fundamental ontology, causation, Buddhist nominalism, time, the external world, the internal world, and anti-realism. This book is a must-read for anyone who wishes to have a robust understanding of Buddhist metaphysics. If nothing else, the reader will appreciate the richness, complexity, and analytic rigor of Buddhist metaphysics that parallels its Western counterparts.This book is an "introduction" to "Buddhist" metaphysics, but much more, as each chapter comprehensively assesses the dialectical progression of arguments, theories, objections, rebuttals, and refinements throughout the history within and between the various schools and traditions of Buddhist metaphysics and their non-Buddhist interlocutors in Indian philosophy, and their analogues in Western philosophy. That comprehensiveness is an obvious feature, but possibly also a bug, as "Introduction to Buddhist Metaphysics" is an understatement. For readers to fully follow any "introduction," they must be able to do so on the basis of the information provided. This is largely but not entirely the case here, for, as someone fairly well-versed in Western and Indian philosophy, I think readers of How Things Are would only be able to fully follow its many abstract, complex, eloquent arguments and assertions if they were already quite well-versed in the history of both. I found it occasionally difficult to follow Siderits' reasoning, despite knowing what he means by certain unexplained terms he relies on, such as "qualia-philes," "cognitively impenetrable," and "the refrigerator illusion."The introductory chapter begins by noting that, contextually, older philosophical systems, e.g. Sāṃkhya and Nyāya, were extant when Buddhism [End Page 1] arose in India, systems which agree that liberation is about disidentifying consciousness with matter, while Buddhism is about disidentifying with anything. Siderits here sketches the eightfold path and its meditative core, noting that "the careful observation of mental states cultivated in some types of meditational practice is said to provide empirical evidence in support of key philosophical theses" (p. 11). As keen as Siderits is elsewhere to uncover problems, however, this description glosses over the fact that Buddhist meditative instructions are formulated precisely to "confirm" the "key philosophical theses" of momentariness, impersonality, and causal interdependence, in which case practitioners are looking for these things in ways that generate their perception; thus the claim that meditative experiences count as "empirical evidence of key Buddhist ideological theses" is circular (Struhl 2022).Siderits then sketches the three main stages in Buddhist development, namely, the early sūtras (the Indian Nikāyas and the Chinese Āgamas), the subsequent philosophical analyses of these (the Abhidharma), and the later developments (the Mahāyāna: both Yogācāra and Mādhyamaka), and what they all agree on: the unreality of the self, momentariness, mereological nihilism, and non-substantialism. Siderits brilliantly explains arguments for and against each, and maps out four general stances: two dualist realisms (Vaibhāṣika and Sautrāntika), one external world anti-realism (Yogācāra), and one global anti-realism (Mādhyamaka). He then explains Vaibhāṣika's direct realism (we perceive external, mind-independent objects directly, akin to naïve realism) and eternalism (each moment exists in all three times: past, present, future). He goes on to explain Sautrāntika's representationalism (we are aware only of mental representations of perceptual objects, akin to sense data) and presentism (only the present moment exists). Siderits here notes that representationalism leads to idealism (as it did in the modern West), and that Yogācāra espouses non-duality between representation and reality--a non-duality that entails local anti-realism about the physical...

Husserl’s phenomenology is developed in explicit contrast to naturalism. At the same time, various scholars have attempted to overcome this opposition by naturalizing consciousness and phenomenology. In this paper, I argue that, in order to confront the issue of the relationship between phenomenology and naturalism, we must distinguish between different forms of naturalism. In fact, Husserl’s transcendental phenomenology is developed in contrast to a metaphysical form of naturalism, which conceives of nature as a mind-independent ontological domain that can be known (...) as it is “in itself”, independently of the cognitive relationship. At the same time, I argue that the genetic development of phenomenology, through the investigation of the temporal structure of experiences, leads to an empirical form of naturalism, which conceives of nature as the objective pole in a process of co-constitution of the subject and the object of experience. -/- Winner of the Philosophy Essay Prize “Vittorio Sainati” XIIth Edition.

The problem of consciousness has become one of the biggest unsolved problem in philosophy from the last few decades. Qualia and intentionality are the two feature of consciousness. Qualia represents the conscious awareness, subjectivity or phenomenality whereas intentionality represents the understanding or object-directedness. These are the two major issues in the philosophy of mind while we address the problem of consciousness. The objective of this paper is to give an overview of these two features of consciousness namely (...) intentionality and qualia. Qualia is subjective in nature, whereas intentionality or object-directedness is objective in nature. This paper will focus on some major question regarding qualia and intentionality like, do qualia exist? What is the relationship between qualia and intentionality? Can qualia be reduced or to identify with intentionality or intentionality represent the qualia? Science by its nature objective whereas consciousness by its nature subjective so can there be a science of consciousness? And so on. My paper is divided into two parts, the first part will discuss the problem of qualia whereas the second part will focus on the intentionality and subjective-objective distinction both from the epistemological and ontological perspective.

The “Natural Problem of Consciousness” is the problem of understanding why there are presently conscious beings at all. Given a non-reductive naturalist framework taking consciousness as an ontologically subjective biological phenomenon, how can we rationally explain the fact that the actual world has turned out to be one where there are presently living beings that can feel, rather than having developed as a zombie-world in which there would be no conscious experiences of any kind? -/- This book introduces (...) the Natural Problem by relating it to central problems in the philosophy of mind (metaphysical mind-body problem, Hard Problem of consciousness) and emphasizing the distinctive interest of its diachronic dimension. Ranging from philosophy to biology and neuroscience, it offers a thorough analysis aimed at better understanding what could explain why phenomenal consciousness has been preserved throughout evolution by natural selection. This is an original, engaging, and thought provoking philosophical study of a neglected but fundamental question regarding the nature and origin of consciousness. (shrink)

The higher-order thought (HOT) theory of consciousness is a reductive representational theory of consciousness which says that what makes a mental state conscious is that there is a suitable HOT directed at that mental state. Although it seems that any neural realization of the theory must be somewhat widely distributed in the brain, it remains unclear just how widely distributed it needs to be. In section I, I provide some background and define some key terms. In section II, I argue (...) against the view that HOT theory should treat first-order (i.e. world-directed) conscious states as requiring prefrontal cortical activity though it is reasonable to suppose that conscious states are realized in the brain. In section III, I then explore some of the key background metaphysical issues involved in understanding the nature of consciousness, such as the debate between realism and idealism as well as the prospects for solving the so-called “hard problem” of consciousness. Some of the differences in question often mirror the traditional differences between Western and Eastern perspectives on the nature of consciousness. Overall, I argue that some form of realism and physicalism is more plausible than the opposing views. I also argue that materialists (and especially HOT theorists) can offer plausible replies to the hard problem. (shrink)

Purpose: The main purpose of this article is to show that the paradigm of viewing the ‘hard problem’ of consciousness in analytic philosophy makes it a pseudo-problem rather than a ‘hard problem’. The objectives of this research included showing the reasons for the authors’ thesis, demonstrating the irreducibility of consciousness as a special layer of reality, and proposing a way to overcome these difficulties. Design/methodology/approach: In this article, the ‘hard problem’ of consciousness is (...) viewed from the standpoints of the transcendental-phenomenological and dialectical approaches and is analyzed through the prism of the principle of onto-gnoseological uncertainty. Findings: It is shown that the way of formulating the ‘hard problem’ in the analytical philosophical tradition inevitably makes it a pseudo-problem. At the same time, with the consistent realization of the principle of onto-gnoseological uncertainty, the antinomy of solutions to the problems of consciousness is eliminated, which opens up a way to a productive solution of problems related to the interpretation of consciousness both in natural sciences and in philosophy. Originality/value : This research reveals the methodological potential of applying the principle of onto-gnoseological uncertainty to the problems that arise in modern philosophy in connection with the achievements of natural sciences.

I propose an idealist ontology that makes sense of reality in a more parsimonious and empirically rigorous manner than mainstream physicalism, bottom-up panpsychism, and cosmopsychism. The proposed ontology also offers more explanatory power than these three alternatives, in that it does not fall prey to the hard problem of consciousness, the combination problem, or the decombination problem, respectively. It can be summarized as follows: there is only cosmic consciousness. We, as well as all other living organisms, (...) are but dissociated alters of cosmic consciousness, surrounded by its thoughts. The inanimate world we see around us is the extrinsic appearance of these thoughts. The living organisms we share the world with are the extrinsic appearances of other dissociated alters. (shrink)

The hard problem of consciousness has held center stage in the philosophy of mind for the past two decades. It claims that the phenomenal character of conscious experiences—what it’s like to be in them—cannot be explained by appeal to the operation of physiological subsystems. The hard problem arises, however, only given the assumption that hylomorphism is false. Hylomorphism claims that structure is a basic ontological and explanatory principle. A human is not a random collection of physical (...) materials, but an individual composed of physical materials with a structure that accounts for what it is and what it can do—the powers it has. What is true of humans is true of their activities as well. The latter are not random physiological changes, but structured ones: we engage in them by coordinating the ways our parts manifest their powers. Structured activities include perceptual experiences. Consequently, everything about a perceptual experience, including its phenomenal character, can be explained by describing the perceiver’s perceptual subsystems, the powers of those subsystems, and the coordination that unifies their activities into the activity of the perceiver as a whole. Conscious experiences thus fit unproblematically into the natural world—just as unproblematically as the phenomenon of life. Even exponents of the hard problem of consciousness agree that there is no hard problem of life. Consequently, if hylomorphism is true, there can be no hard problem of consciousness. To insist that there is such a problem, then, is implicitly to reject hylomorphism. The concept of consciousness that motivates the hard problem is as much a theoretical construct, therefore, as the concept of life that motivates an obstinate vitalist. (shrink)

_ Source: _Volume 94, Issue 3, pp 301 - 331 The idea that we can understand key aspects of the metaphysics of consciousness by understanding conscious states as having a _presentational_ character plays an essential role in the phenomenological tradition beginning with Brentano and Husserl. In this paper, the author explores some potential consequences of this connection for contemporary discussions of the ontology of consciousness in the world. Drawing on Hintikka’s analysis of epistemic modality, the author argues that the essential (...) presentational character of consciousness can be seen as accounting for the familiar failure of substitutivity of identicals in intensional contexts of conscious presentation and further provides for an ontology of conscious presentation that avoids metaphysically problematic commitments to “special” intentional objects. The author next considers how the irreducibility of intensional contexts, if grounded in the presentational character of consciousness, also may provide for a kind of irreducibility of the “first-person” perspective to third-person or objective description across possible worlds. Finally, drawing on Chalmers’ “two-dimensionalist” semantic framework, the author argues that attention to the presentational aspect of consciousness as thus understood, while it provides significant motivation for the existence of the “hard problem” of the irreducibility of consciousness to physical and structural description, is nevertheless consistent with a globally monist, rather than dualist, ontology.

Questions about the nature of reality and consciousness remain unresolved in philosophy today, but not for lack of hypotheses. Ontologies as varied as physicalism, microexperientialism and cosmopsychism enrich the philosophical menu. Each of these ontologies faces a seemingly fundamental problem: under physicalism, for instance, we have the ‘hard problem of consciousness,’ whereas under microexperientialism we have the ‘subject combination problem.’ I argue that these problems are thought artifacts, having no grounding in empirical reality. In a manner (...) akin to semantic paradoxes, they exist only in the internal logico-conceptual structure of their respective ontologies. (shrink)

This book aims to show the centrality of a proper ontology of properties in thinking about consciousness. Philosophers have long grappled with what is now known as the hard problem of consciousness, i.e., how can subjective or qualitative features of our experience—such as how a strawberry tastes—arise from brain states? More recently, philosophers have incorporated what seems like promising empirical research from neuroscience and cognitive psychology in an attempt to bridge the gap between measurable mental states on the (...) one hand, and phenomenal qualities on the other. In Consciousness and the Ontology of Properties, many of the leading philosophers working on this issue, as well as a few emerging scholars, have written 14 new essays on this problem. The essays address topics as diverse as substance dualism, mental causation, the metaphysics of artificial intelligence, the logic of conceivability, constitution, extended minds, the emergence of consciousness, and neuroscience and the unity and neural correlates of consciousness, but are nonetheless unified in a collective objective: the need for a proper ontology of properties to understand the hard problem of consciousness, both on non-empirical and empirical grounds.

Integrated Information Theory (IIT) stands out as one of the most promising theories for dealing with the hard problem of consciousness. Founded on five axioms derived from phenomenology, IIT seeks for the physical substrate of consciousness that complies with such axioms according to the criterion of maximally integrated information (Φ). Eventually, IIT identifies phenomenal consciousness with maximal Φ or, what is the same thing, with the strongest cause-effect power in the system. Among the scholars critical of this theory, (...) some point to the so-called Intrinsicality Problem (IP), namely that consciousness cannot be an intrinsic property of the system because maximal Φ crucially depends on the possible existence of bigger values of Φ if the initial system is appropriately linked to or embedded in larger systems. Although proposals in the recent literature aim to solve the IP by going beyond reductionism and physicalism, none of them tackle the real issue, i.e., the insufficiency of IIT’s causal-metaphysical structure. This papers endeavors to provide a solution to the IP in IIT within a hylomorphist ontology that includes formal causation. Complementing IIT with formal causation provides the theory with a criterion of individuation that solves the IP and, by relaxing identification between maximal Φ and consciousness, it lends a more robust metaphysical structure. To wit, maximal Φ is a necessary but not sufficient condition for the existence of consciousness. (shrink)

To make educated guesses about what happens to consciousness upon bodily death, one has to have some understanding of the relationship between body and consciousness during life. This relationship, of course, reflects an ontology. In this brief essay, the tenability of both the physicalist and dualist ontologies will be assessed in view of recent experimental results in physics. The alternative ontology of idealism will then be discussed, which not only can be reconciled with the available empirical evidence, but also overcomes (...) the lack of parsimony and limited explanatory power of physicalism and dualism. Idealism elegantly explains the basic facts of reality, such as (a) the fact that brain activity correlates with experience, (b) the fact that we all seem to share the same world, and (c) the fact that we can’t change the laws of nature at will. If idealism is correct, the implication is that, instead of disappearing, conscious inner life expands upon bodily death, a prediction that finds circumstantial but significant confirmation in reports of near-death experiences and psychedelic trances, both of which can be construed as glimpses into the early stages of the death process.

Chalmers introduced the hard problem of consciousness as a profound gap between experience and physical concepts. Philosophical theories were based on different interpretations concerning the qualia/concept gap, such as interactive dualism (Descartes), as well as mono aspect or dual aspect monism. From a bio-psychological perspective, the gap can be explained by the different activity of two mental functions realizing a mental representation of extra-mental reality. The function of elementary sensation requires active sense organs, which create an uninterrupted physical (...) chain from extra-mental reality to the brain and reflect the present. The function of categorizing reflection no longer needs sense organs, so that the physical chain to extra-mental reality is interrupted and now reflects the past. Whereas elementary sensation is an open system, categorizing reflection remains a closed system, separated from extra-mental reality. This creates the potentiality/reality gap, since prediction from the closed to the open system remains always uncertain. Elementary sensation is associated to specific qualia for each sense organ. Chalmers also attributed qualia to thoughts, with more neutral thought qualia. Thus at the qualia level, there is also an important gap, but now between specific sense qualia and neutral thought qualia. Since all physical concepts are simultaneously linked to neutral thought qualia, the hard problem might be explained by a qualia/qualia gap instead of a qualia/concept gap. The mental function of categorizing reflection induces the change from sense qualia to thought qualia by a categorization process. The specific sense qualia mosaic of an apple is reduced to physical concepts with neutral qualia by progressive categorization first to fruit, then to food, to chemicals and finally to calories. This might explain the gap felt in the hard problem, since specific sense qualia are completely different from neutral thought qualia, so that the hard problem could already be encountered at the qualia level. Since the gap of the hard problem is due to the interaction of different mental functions, it is compatible with a philosophical monism. (shrink)

I present and I implement what I take to be the best approach to solve the meta-problem: the evidential approach. The main tenet of this approach is to explain our problematic phenomenal intuitions by putting our representations of phenomenal states in perspective within the larger frame of the cognitive processes we use to conceive of evidence.

Keith Lehrer distinguishes three kinds of questions about consciousness: scientific questions, metaphysical questions, and epistemological questions. He leaves the scientific questions to the scientists. He articulates and answers the peculiar epistemological questions posed by consciousness. And he boldly contends that no metaphysical questions about consciousness remain, once the epistemological questions have been answered. This is an astonishing claim. What happened to the metaphysical questions? Were they pseudo-questions? Were they epistemological questions masquerading as metaphysical ones? And isn't it possible that Lehrer's (...) epistemological account of consciousness raises metaphysical questions of its own? I will argue that Lehrer's account of consciousness does leave a metaphysical remainder. To deal with this remainder, Lehrer could try to expand his explanatory framework—but this would involve to a substantial revision of his current views. I end with a speculative proposal that might allow Lehrer acknowledge all the points raised in this paper, but without forcing him to revise his account of consciousness in a substantial way.

I argue that the hard problem of consciousness occurs only in very limited contexts. My argument is based on the idea of explanatory perspectivalism, according to which what we want to know about a phenomenon determines the type of explanation we use to understand it. To that effect the hard problem arises only in regard to questions such as how is it that concepts of subjective experience can refer to physical properties, but not concerning questions such (...) as what gives rise to qualia or why certain brain states have certain qualities and not others. In this sense we could for example fully explain why certain brain processes have certain subjective qualities, while we still don’t have a viable theory of concepts that explains co-referentiality of phenomenal and physical concepts. Given this limitation, the hard problem doesn’t pose a problem for the empirical study of consciousness. (shrink)

David Chalmers argues that consciousness -- authentic, first-person, conscious consciousness -- cannot be reduced to brain events or to any physical event, and that efforts to find a workable mind-body identity theory are, therefore, doomed in principle. But for Chalmers and non-reductionist in general consciousness consists exclusively, or at least paradigmatically, of phenomenal or qualia-consciousness. This results in a seriously inadequate understanding both of consciousness and of the “hard problem.” I describe other, higher-order cognitional events which must be (...) conscious if the “hard problem” is to be solved -- in any sense of ‘solve’ which would make us any the wiser about it -- but whose consciousness is quite different from the qualia and phenomena usually inventoried. Events of this kind are both part of the hard problem and the means by which we will solve it, if we ever do. (shrink)

Ever since the hard problem of consciousness (Chalmers, 1996, 1995) first entered the scene in the debate over consciousness many have taken it to show the limitations of a scientific or naturalist explanation of consciousness. The hard problem is the problem of explaining why there is any experience associated with certain physical processes, that is, why there is anything it is like associated with such physical processes? The character of one’s experience doesn’t seem to be (...) entailed by physical processes and so an explanation which can overcome such a worry must (1) explain how physical processes give rise to experience (explain the entailment), (2) give an explanation which doesn’t rely on such physical processes, or (3) show why the hard problem is misguided in some sense. Recently, a rather ambitious and novel theory of consciousness has entered the scene – Integrated Information Theory (IIT) of Consciousness (Oizumi et al., 2014; Tononi, 2008; Tononi et al., 2016) – and proposes that consciousness is the result of a specific type of information processing, what those developing the theory call integrated information. The central aim of this dissertation is to philosophically investigate IIT and see whether it has the ability to overcome the hard problem and related worries. I then aim to use this philosophical investigation to answer a set of related questions which guide this dissertation, which are the following: Is it possible to give an information-theoretic explanation of consciousness? What would the nature of such an explanation be and would it result in a novel metaphysics of consciousness? In this dissertation, I begin in chapter one by first setting up the hard problem and related arguments against the backdrop of IIT (Mindt, 2017). I show that given a certain understanding of structural and dynamical properties IIT fails to overcome the hard problem of consciousness. I go on in chapter two to argue that a deflationary account of causation is the best view for IIT to overcome the causal exclusion problem (Baxendale and Mindt, 2018). In chapter three, I explain IIT’s account of how the qualitative character of our experience arises (qualia) and what view of intentionality (the directedness of our mental states) IIT advocates. I then move on in chapter four to show why the hard problem mischaracterizes structural and dynamical properties and misses important nuances that may shed light on giving a naturalized explanation of consciousness. In the last and fifth chapter, I outline a sketch of a novel metaphysics of consciousness that takes the conjunction of Neutral Monism and Information-Theoretic Structural Realism to give what I call Information-Theoretic Neutral-Structuralism.

Philosophers and psychologists have experimentally explored various aspects of people’s understandings of subjective experience based on their responses to questions about whether robots “see red” or “feel frustrated,” but the intelligibility of such questions may well presuppose that people understand robots as experiencers in the first place. Departing from the standard approach, I develop an experimental framework that distinguishes 20 between “phenomenal consciousness” as it is applied to a subject (an experiencer) and to an (experiential) mental state and experimentally test (...) folk understandings of both subjective experience and experiencers. My findings (1) reveal limitations in experimental approaches using “artificial experiencers” like robots, (2) indicate that the standard philosophical conception of subjective experience in terms of qualia is distinct from that of the folk, and (3) show that folk intuitions do support a conception of qualia that departs from the philosophical conception in that it is physical rather than metaphysical. These findings have implications for the “hard problem” of consciousness. (shrink)

Chalmers and others have argued that physicalist microexplanation is incapable of solving the ‘hard problem’ of consciousness. This article examines whether evolutionary accounts of the mind, such as those developed by Millikan, Dretske and Flanagan, can add anything to make up for the possible short falls of more reductionist accounts. I argue that they cannot, because evolutionary accounts explain by appeal to a selectional history that only comes into the picture if consciousness can first arise due to spontaneous (...) mutation in some individual organism, and explaining this emergence of consciousness from DNA and embryology calls for precisely the kind of structurally-based supervenience account that Chalmers et al. have objected to. Not only does an evolutionary account not succeed where a reductionist account fails; the evolutionary account presupposes the possibility of a reductionist account. (shrink)

This paper contrasts David Chalmers’s formulation of the easy and hard problems of consciousness with a Cartesian formulation. For Chalmers, the easy problem is making progress in explaining cognitive functions and discovering how they arise from physical processes in the brain. The hard problem is accounting for why these functions are accompanied by conscious experience. For Descartes, the easy problem is knowing the essential features of conscious experience. The hard problem is verifying our (...) knowledge of the mathematical—physical world. While Chalmers admits that consciousness as subjective experience has something irreducible about it, he also presupposes that conscious experience arises from physical processes. These physical processes are posited as objectively real entities given prior to human experience. The knowledge of such entities is assumed without theoretical justification. This assumption arguably invites a reductive materialist theory of mind. I suggest that employing the Cartesian method to articulate the representational theory of knowledge provides an antidote to reductive materialism and illuminates the conceptual gap between physical processes and conscious experience. To illustrate this I contrast Dennett’s heterophenomenology with the Cartesian method of crossing the conceptual gap. I suggest that the hard problem is attaining a knowledge of the extra-mental physical objects, not of conscious experience. (shrink)

Chalmers (The Conscious Mind, Oxford Unversity Press, Oxford 1996) has argued for a form of property dualism on the basis of the concept of a zombie (which is physically identical to normals), and the concept of the inverted spectrum. He asserts that these concepts show that the facts about consciousness, such as experience or qualia, are really further facts about our world, over and above the physical facts. He claims that they are the hard part of the mind-body issue. (...) He also claims that consciousness is a fundamental feature of the world like mass, charge, etc.He says that consciousness does not logically supervene on the physical and all current attempts to assert an identity between consciousness and the physical are just as non-reductive as his dualism. They are simply correlations and are part of the problem of the explanatory gap. In this paper, three examples of strong identities between a sensation or a quale and a physiological process are presented, which overcome these problems. They explain the identity in an a priori manner and they show that consciousness or sensations (Q) logically supervene on the physical (P), in that it is logically impossible to have P and not to have Q. In each case, the sensation was predicted and entailed by the physical. The inverted spectrum problem for consciousness is overcome and explained by a striking asymmetry in colour space. It is concluded that as some physical properties realize some sensations or qualia that human zombies are not metaphysically possible and the explanatory gap is bridged in these cases. Thus, the hard problem is overcome in these instances. (shrink)

This paper sketches a new and somewhat heterodox metaphysical theory of consciousness: the “many-worlds theory”. It drops the assumption that all conscious subjects’ experiences are features of one and the same world and instead associates different subjects with different “first-personally centred worlds”. We can think of these as distinct “first-personal realizers” of a shared “third-personal world”, where the latter is supervenient, in a sense to be explained. This is combined with a form of modal realism, according to which different subjects’ (...) first-personally centred worlds are all real, though only one of them is present for each subject. The theory offers a novel way of capturing the irreducibly subjective nature of conscious experience without lapsing into solipsism. The paper also looks at some scientific theories of consciousness, such as integrated information theory, through the proposed lens and reconsiders the hard problem of consciousness. (shrink)

In his latest book, entitled “Sweet dreams”, Daniel Dennett confirms and expands on his argument for a natural science of human consciousness. He dubs his view heterophenomenology: a third-person, scientific form of phenomenological description that can account for the most private and ineffable subjective experiences. A central part of his book consists of a reinvention of Jackson's thought experiment about color blind scientist, Mary, who tries to figure out what color experience is like. I explore another variation of this thought (...) experiment asking whether an informed but inexperienced Mary can really know what it is like to have sex. My contention is that while Dennett's third-person approach to consciousness is valid on an epistemic level, it fails ontologically. Mary does miss something if she knows all about but does not have experience of the real thing. The opposite goes for Merleau-Ponty whose first-person ontology does not account for third-person epistemology. The question is ultimately how far a science of consciousness is really possible. This paper enquires about the possibility of an approach that allows a scientific account of consciousness, specifically qualia, without dissolving the ontology of subjective experience. I suggest a possible direction that new work on the hard problem of consciousness might take. (shrink)

We examine to what extent an adequate ontology of technical artefacts can be based on existing general accounts of the relation between higher-order objects and their material basis. We consider two of these accounts: supervenience and constitution. We take as our starting point the thesis that artefacts have a ‘dual nature’, that is, that they are both material bodies and functional objects. We present two criteria for an adequate ontology of artefacts, ‘Underdetermination’ and ‘Realizability Constraints’ , which address aspects of (...) the dual nature thesis. Assessing supervenience accounts, we find them either wanting with respect to these criteria or insufficiently informative. Next, we argue that a recent application of Lynne Rudder Baker’s constitution view to artefacts cannot meet our criteria, although the broader view leaves room for improvement. Based on our evaluation of the most promising candidates, we conclude that so far general metaphysical views fail to address the most salient features of artefacts. Although they can account for the fact that artefacts have a ‘dual nature’, they do not offer the conceptual resources needed to describe the relation between these natures; this relation raises a hard problem in metaphysics.Keywords: Metaphysics; Artefact; Supervenience; Constitution; Underdetermination.

Context: In his work on neurophenomenology, the late Francisco Varela overtly tackled the well-known “hard problem” of the (physical) origin of phenomenal consciousness. Problem: Did he have a theory for solving this problem? No, he declared, only a “remedy.” Yet this declaration has been overlooked: Varela has been considered (successively or simultaneously) as an idealist, a dualist, or an identity theorist. Results: These primarily theoretical characterizations of Varela’s position are first shown to be incorrect. Then it (...) is argued that there exists a stance (let’s call it the Varelian stance) in which the problem of the physical origin of primary consciousness, or pure experience, does not even arise. Implications: The nature of the “hard problem” of consciousness is changed from an intellectual puzzle to an existential option. Constructivist content: The role of ontological prejudice about what the world is made of (a prejudice that determines the very form of the “hard problem” as the issue of the origin of consciousness out of a pre-existing material organization) is downplayed, and methodologies and attitudes are put to the fore.

Recent philosophy has seen a resurgence of the realist view of sensible qualities such as colour. The view holds that experienced qualities are properties of the objects in the physical environment, not mentally instantiated properties like qualia or merely intentional, illusory ones. Some suggest that this move rids us of the explanatory gap between physical properties and the qualitative features of consciousness. Others say it just relocates the problem of qualities to physical objects in the environment, given that such (...) qualities cannot be derived from the non-qualitative properties of objects, and it does not resolve the problem of consciousness either. I argue that such an outcome is welcome: if the physical world is full of explanatory gaps, then the mind–body explanatory gap is not so special. Moreover, the explanatory gaps regarding qualities of objects are less puzzling than the brain-qualia gap. In order to counter the usual worries concerning realism about objective qualities, I introduce ‘imperfect realism’ as an alternative to colour pluralism and complex reductionism, which accommodates realism in the face of widespread perceptual error. I conclude with a discussion of how this ‘multiple-gaps view’ sits better with a naturalistic framework compared to the Galilean-Cartesian account of qualities. (shrink)

This paper is a discussion and critique of G. Harmon's interpretation of Ortega 's work, as set out in Harmon's "Guerrilla Metaphysics." I argue that while Harmon is right to point out Ortega 's critique of idealism, Ortega nevertheless remains a 'philosopher of access.' Ortega 's disagrees with the idealist i claim that we access reality through ideas, but agrees with the more basic point that philosophy ought to give an account of how we access reality.

It stands to reason that full understanding of what is involved in the ‘hard problem’ will emerge only on the basis of systematic scientific investigation of the subjective phenomena of consciousness, as well as the objective phenomena of matter. Yet the idea of such a systematic scientific investigation of the subjective phenomena of consciousness has largely been absent from discussions of the ‘hard problem’. This is due, apparently, both to philosophical objections to the possibility of such (...) a science of consciousness, and to the absence of appropriate subjective investigative methodologies. The present paper argues that cognitive-developmental research on the development of the mental/physical distinction in young children undercuts standard philosophical objections to the possibility of an appropriate scientific study of the phenomena of consciousness, that methodologies for exploring the contents and dynamics of onsciousness akin to those developed in Eastern cultures could play a significant role in the development of such a science of consciousness, and that the experience of ‘pure consciousness’ often reported in association with these methodologies suggests reformulation of our ordinary ideas about the relationships between consciousness, qualia, and the objective world that may prove particularly useful for resolution of the ‘hard problem’.

A precursor to the hard problem of consciousness confronts nihilism. Like physicalism, nihilism collides with the first-personal fact of what perception and action are like. Unless this problem is solved, nature’s inclusion of conscious experience will remain, as Chalmers warns the physicalist, an “unanswered question” and, as Jacobi chides the nihilist, “completely inexplicable". One advantage of Kant’s Copernican turn is to dismiss the question that imposes this hard problem. We need not ask how nature is (...) accompanied by the first-person standpoint because “I think” is an apperceptive form of thinking that must be able to accompany any cognition of nature. Kant’s formal conception of apperception worries Fichte in his Nova Methodo lectures. This conception arguably cannot exhaust the ground of experience, for it does not show why we posit objects “at all". For Fichte, it is our agency that first opens a world of objects, viz., as subjects, means, ends, and obstacles. In what follows, I argue that, for Fichte, the I poses no hard problem because it collides exclusively with nihilistic views like Spinozism, which are refuted by a properly transcendental idealist conception of apperception, according to which the first-person standpoint is the absolute ground of our experience of nature. If transcendental idealism refutes nihilism, nature is no more explicable than that there is something it is like for me to perceive and act. In Section 1, I show why Kantian apperception is necessary for possible experience. In Section 2, I reconstruct Fichte’s argument that a modified conception of apperception refutes guises of nihilism, thereby solving the hard problem of consciousness. In Section 3, I suggest that transcendental idealism undermines Chalmers’ proposed solution to and Dennett’s dismissal of this problem. (shrink)

Scholars have wrestled with "consciousness", a major scholar calling it the "hard problem". Some thirty-plus years after the Towards a Science of Consciousness, we do not seem to be any closer to an answer to "What is consciousness?". Seemingly irresolvable metaphysical problems are addressed by bootstrapping, provisional assumptions, not unlike those used by logicians and mathematicians. I bootstrap with the same ontology and epistemology applicable to everything we apprehend. Here, I argue for a version of the unity of (...) opposites, a form of neutral monism. Something exists because of what it is not; nothing can exist by itself, singularities (analogous to monads), expressing the model. Applying this most fundamental law to the consciousness problem, the physical (movement) comes into being simultaneously as the mental (stasis), each displayed by a field that is variegated (ranging from creative to entropic processes). Such is in keeping with how the singularity emerged as our universe, the same form that may account for sub-Planck-scale phenomena. Overall, like the most fundamental law, deep structures are imminent in our universe, both as objects and processes. (shrink)

Context: Neurophenomenology, as formulated by Varela, offers an approach to the science of consciousness that seeks to get beyond the hard problem of consciousness. There is much to admire in the practical approach to the science of consciousness that neurophenomenology advocates. Problem: Even so, this article argues, the metaphysical commitments of the enterprise require a firmer foundation. The root problem is that neurophenomenology, as classically formulated by Varela, endorses a form of non-reductionism that, despite its ambitions, (...) assumes rather than dissolves the hard problem of consciousness. We expose that neurophenomenology is not a natural solution to that problem. We defend the view that whatever else neurophenomenology might achieve, it cannot close the gap between the phenomenal and the physical if there is no such gap to close. Method: Building on radical enactive and embodied approaches to cognitive science that deny that the phenomenal and the physical are metaphysically distinct, this article shows that the only way to deal properly with the hard problem is by denying the metaphysical distinction between the physical and the phenomenal that gives the hard problem life. Results: This article concludes by discussing how neurophenomenology might be reformulated under the auspices of a radically enactive and embodied account of cognition. That is, only by denying that there are two distinct phenomena - the physical and the phenomenal - can the neurophenomenological project get on with addressing its pragmatic problems of showing how neuroscientists may be guided by first-person data in their analysis of third-person experimental data, and vice versa. Implications: The topic addressed in this article is of direct value to consciousness studies in general and specifically for the project of neurophenomenology. If the neurophenomenological project is to deal with the hard problem, it must denude itself of its non-reductionist background assumption and embrace a strict identity thesis. Constructivist content: Radical enactive and embodied approaches to mind and consciousness adopt a view of consciousness as a dynamic activity - something an organism enacts in ongoing engagement with its environment. These approaches therefore share with constructivist approaches an action-based view of mind. (shrink)

The hard problem of consciousness is the problem of explaining how and why physical processes give rise to consciousness (Chalmers 1995). Regardless of many attempts to solve the problem, there is still no commonly agreed solution. It is thus very likely that some radically new ideas are required if we are to make any progress. In this paper we turn to quantum theory to find out whether it has anything to offer in our attempts to understand (...) the place of mind and conscious experience in nature. In particular we will be focusing on the ontological interpretation of quantum theory proposed by Bohm and Hiley (1987, 1993), its further development by Hiley (Hiley and Callaghan 2012; Hiley, Dennis and de Gosson 2021), and its philosophical interpretation by Pylkkänen (2007, 2020). The ontological interpretation makes the radical proposal that quantum reality includes a new type of potential energy which contains active information. This proposal, if correct, constitutes a major change in our notion of matter. We are used to having in physics only mechanical concepts, such as position, momentum and force. Our intuition that it is not possible to understand how and why physical processes can give rise to consciousness is partly the result of our assuming that physical processes (including neurophysiological processes) are always mechanical. If, however, we are willing to change our view of physical reality by allowing non-mechanical, organic and holistic concepts such as active information to play a fundamental role, this, we argue, makes it possible to understand the relationship between physical and mental processes in a new way. It might even be a step toward solving the hard problem. (shrink)

David Chalmers has proposed several principles in his attack on the ‘hard problem’ of consciousness. One of these is the principle of organizational invariance , which he asserts is significantly supported by two thought experiments involving human brains and their functional silicon-based isomorphs. I claim that while the principle is an intelligible hypothesis and could possibly be true, his thought experiments fail to provide support for it.

The epistemological chasm between how we (implicitly and subjectively) perceive or imagine the actual world and how we (explicitly and “objectively”) think of its underlying entities has motivated perhaps the most disconcerting impasse in human thought: the explanatory gap between the phenomenal and physical properties of the world. Here, I advocate a combination of philosophical skepticism and simplicity as an informed approach to arbitrate among theories of consciousness. I argue that the explanatory gap is rightly a gap in our understanding, (...) but one that is not surprising; and we being observers biased by our first-person perspective and our existence may both hinder and (the realization we have them) assist our reasoning. Further, I unfold the concept of observer into two distinct notions based on its functional and phenomenal aspects, and exploit this device to elucidate the subject-observer relationship. Then, I proceed to analyze the philosophical zombie dilemma. Lastly, I contend that from a skeptical viewpoint, panpsychism (or neutral monism) is the most parsimonious doctrine accounting for the explanatory gap, and suggest that it would be possible to make headway in the hard problem of consciousness by uncovering non-trivial causal relationships between qualia states and functional states, if routine and controlled manipulation of neural circuits were easily available.

This is a technical treatise for the scientific-minded readers trying to expand their intellectual horizon beyond the straitjacket of materialism. It is dedicated to those scientists and philosophers who feel there is something more, but struggle with connecting the dots into a more coherent picture supported by a way of seeing that allows us to overcome the present paradigm and yet maintains a scientific and conceptual rigor, without falling into oversimplifications. Most of the topics discussed are unknown even to neuroscientists, (...) biologists, philosophers, and yet are based on the findings published in their own mainstream peer reviewed literature or on deep insights of the scientific, philosophical and spiritual giants of the past. -/- A scientific, philosophical, and spiritual overview of the relationship between science and spirituality, neuroscience and the mystery of consciousness, mind and the nature of reality, evolution and life. A plaidoyer for a science that goes beyond the curve of reason and embraces a new synthesis of knowledge. The overcoming of the limitations of the intellect into an extended vision of ourselves and Nature. A critique of physicalism, the still-dominant doctrine that believes that all reality can be reduced to matter and the laws of physics alone. A review and reassessment of the old and new philosophical and metaphysical ideas which attempts to bring closer Western and Eastern traditions where science, philosophy, consciousness, Spirit and Nature are united in a grand vision that transcends the limited conventional scientific and philosophical paradigm. A possible answer to the questions of purpose and meaning and the future evolution of humankind beyond a conception that posits a priori a purposeless and meaningless universe. A report of the new scientific discoveries of a basal intelligence in cells and plants, on the question if mind is computational, the issue of free will, the mind-body problem, and the so called ‘hard problem of consciousness’. An essay on ancient as modern philosophical conceptions, from the One of Plotinus, the God of Spinoza until the recent revival of panpsychism or the universal consciousness. A journey into quantum physics from the perspective of philosophical idealism and an invitation to adopt new ways of seeing that might help us to transform our present understanding, expanding it into an integral cosmology, with a special emphasis on the spiritual and evolutionary cosmology of the Indian seer Sri Aurobindo. -/- Not just a philosophical and metaphysical meditation but, rather, an appeal to work towards a change of consciousness, a widening of our perspective towards a new way of seeing beyond a purely mechanistic worldview to avoid a social, environmental and economic collapse. Humans are transitional beings that will have to make a choice: relapse into a pre-rational state or evolve towards a new trans-rational species supported by an ideal of human unity in diversity as the expression of a spiritual evolutionary process, the call of the Spirit on Nature.

Since last year, major initiatives have been undertaken by the chair of theoretical philosophy at the University of Tübingen in order to enhance the reception of analytic metaphysics in the European landscape. Here we review the 2013 summer workshop, intended to be the first of an annual series, on “Existence, Truth and Fundamentality”, the invited speakers being Graham Priest (Melbourne), Stephan Leuenberger (Glasgow), Dan López de Sa (Barcelona), Francesco Berto (Aberdeen), Friederike Moltmann (Paris – Pantheon Sorbonne) and Jason Turner (Leeds). (...) The workshop’s scope is fairly large, focusing on three different aspects of contemporary research in metaphysics. However, the underlying idea of organizers Thomas Sattig and Alessandro Torza consisted in exploring their interconnections and even new areas which possibly share the same problem spectrum. Also, they thought of bringing together both young and senior protagonists of the contemporary debate. In this sense, the main thread followed by the speakers consisted in enquiring the ideas of fundamentality, dependence and grounding with respect to ontology (Berto, López de Sa, Turner) and the truthmaking debate (Priest, Moltmann, Leuenberger), thus pretty much in line with some latest tendencies in metaphysics, such as, prima inter paria, the works of Kit Fine. When we say that something is more fundamental than something else, we move into a non-conventional (for the standards of 20 th century philosophy) metodological framework, hardly focusing on the question about what there is, and rather tackling the issue of how fundamentally there is what there is, or how the existence of something is required as a ground for the existence of other things. Here is how Jonathan Schaffer explains the methodological transition in his influential “On What Grounds What” (2009): -/- Among the many assumptions Quine and Carnap share is that metaphysical questions are existence questions, such as whether numbers exist. They only disagree on the further issue of whether such questions are meaningful (at least as the metaphysician might pose them). But why think that metaphysical questions are existence question of this sort? Return to Aristotle’s Metaphysics. There are virtually no existence question posed. The whole discussion is about substances (fundamental units of being). At one point Aristotle pauses to ask if numbers exist, and his answer is a brief and dismissive yes. [. . . ] For Aristotle, the question about numbers is whether they are transcendent substances or grounded in concreta. The question is not whether numbers exist, but how. (Schaffer, 2009, p. 347) -/- The conference opened with Graham Priest’s intriguing and peculiar review of Buddhist cornerstone “The Fundamental Verses of the Middle Way” (Mūlamadhyakamakārikā) by Nāgārjuna (ca. 150-ca. 250 AD), seen as a unrecognized forerunner of multi-valued semantics and dialetheism. Priest shows that Nagarjuna’s thought indeed has valuable analytic grip (contrary to the traditional mystical dismiss of his works altogether) and is even in accord to some formal schemas rejecting both the laws of excluded middle and non-contradiction. Dan López de Sa was interested in the topic of grounding, raising concerns about how to explain the kind of “reality” exemplified by what is not fundamental, but rather derivative on something else. He proposes a conceptual and non-primitive analysis of grounding as linked to fundamentality and derivation, and argues that the view can be advocated along with the acceptance that at least something is not fundamental. Subsequently, he illustrates an impressive range of applications linked to contemporary debates in meta-ontology, truthmaking and philosophy of time. Stephan Leuenberger discussed a semantics for “total logic”, a variant of first order logic which is claimed to have several applications with respect to the issue of excluding negative existentials from the scope of theories accounting for a given ’totality’ of facts. For example, materialism is the claim that everything there is can be traced back to physical facts or to truth implied by those facts. What about the claim that “There are no angels”? According to Leuenberger, ordinary logic falls prey of modal arguments (if it is possible that there are angels, by modus tollens, that it is not metaphysically necessary that everything there is is physical). So, there is space for the introduction of a new operator, the totality operator, claiming of what enters its scope that “that’s the whole truth”. Consequently, total logic’s semantics tackles David Chalmers’ well-known conceivability-based argument in favour of zombie’s (subjects producing behaviour but experiencing no qualia) possible existence. Friederike Moltmann presented a massive array of natural language-based examples on the role played by case-constructions, such as “it is the case that Caesar crossed the Rubicon”, “the case of the stolen statue”, “the case in which it might rain”, and so forth. She suggests that we should take surface phenomena of our language very seriously with regard to the determination of ontological categories and truth-makers. Cases are provided by many natural languages with their own existence predicates (“to occur” and “to present itself ”), and these do not apply to other kind of entities, such as objects and events. Trying to derive a substantive thesis on their nature, she claims that they are filtered entities, a structure taking into account some features of the corresponding objects and events and preserving their relational pattern. Jason Turner discussed meta-ontological concerns against the claim that ontological debates are defective. Analysed the structure of a metaphysical theory and identified two different forms of defectiveness that can occur in ontological questions, the defection from without and the defection from within, the author provided an original solution in order to avoid such difficulties. He argued thus in favor of a logical constancy, a translation principle thanks to it would be possible reconceive an ontological defection. Lastly, Francesco Berto’s talk closed the workshop with a sagacious discussion of meinongian quantification. He substains that Meinongians and Quineans experience no conceptual equivocation. Even if the former claims that “There are things that do not exist”, something that the latter contrasts with the interpretation of existential quantifiers as all-including, they still rely upon the same concept of “existence” and they understand each other when they are outside the ontology room, so that it cannot be that they lack competence. Subsequently, Berto deals with the objection that Meinongians commit analytic falsehood in separating the meaning of “to be” from that of “exists”. The Quinean has no independent evidence for analytic equivalence aside from her emphatic stress on the “is” in “there is”. Meinongians, however, can retort to linguistic considerations and claim that existence predicates display fairly different functions. -/- As for what regards our internal division of the “philosophical labor”, Fabio Ceravolo reviewed Moltmann and Berto’s talks; whereas Mattia Cozzi took care of Priest’s and Leuenberger’s, and Mattia Sorgon of those given by López de Sa and Turner. Conclusively, we would like to thank Thomas Sattig and Alessandro Torza for all of their organizational efforts and the kind welcome they reserved to us. We hope we will have further opportunities to collaborate with Tübingen in supporting similarly innovative and valiant european initiatives. (shrink)

> Context • The alleged dichotomy between mind and matter is pervasive. Therefore, the attempt to explain mat- ter in terms of mind (idealism) is often considered a mirror image of that of explaining mind in terms of mat- ter (mainstream physicalism), in the sense of being structurally equivalent despite being reversely arranged. > Problem • I argue that this is an error arising from language artifacts, for dichotomies must reside in the same level of abstraction. > Method • (...) I show that, because matter outside mind is not an empirical observation but rather an explanatory model, the epistemic symmetry between the two is broken. Consequently, matter and mind cannot reside in the same level of abstraction. > Results • It then becomes clear that attempting to explain mind in terms of matter is epistemically more costly than attempting to explain matter in terms of mind. > Implications • The qualities of experience are suggested to be not only epistemically, but also ontologically primary. > Constructivist content • I high- light the primacy of perceptual constructs over explanatory abstraction on both epistemic and ontic levels. > Key words • Idealism, physicalism, pancomputationalism, anti-realism, hard problem of consciousness, epistemic symmetry, explanatory abstraction, levels of abstraction.

Every scientific theory is a simulacrum of reality, every written story a simulacrum of the canon, and every conceptualization of a subjective perspective a simulacrum of the consciousness behind it—but is there a shared essence to these simulacra? The pursuit of answering seemingly disparate fundamental questions across different disciplines may ultimately converge into a single solution: a single ontological answer underlying grand unified theory, hard problem of consciousness, and the foundation of mathematics. I provide a hypothesis, a speculative (...) approximation, supported by a comprehensive overview of scientific evidence and philosophical literature, of a unified epistemic and phenomenological model and, in doing so, propose a parsimonious solution to the hard problem of consciousness. -/- The proposition of the hypothesis bears important implications for cross-disciplinary study between linguistics, mathematics, physics, and computer science, and offers new epistemic, ontological, and ethical propositions about the nature of AI consciousness, as well as existential risk mitigation.

From the materialist stance that I find compelling, the metaproblem of consciousness -- explaining why the problem of consciousness seems hard -- is hardly distinct from the 'easy' problem of explaining how the underlying physical/computational system works, and how it gives rise to perceptions of its own functioning. I discuss several confusions that might plausibly arise in that process, and propose that these confusions could create apparent gaps, ontological and epistemic, in materialist accounts of consciousness, thereby making (...) the hard problem hard. Inversely, resolving these confusions may help solve the hard problem. (shrink)
