The aim of the paper is to show that the privacy of conscious experience is inconsistent with any kind of physicalism. That is, if you are a physicalist, then you have to deny that more than one subject cannot undergo the very same conscious experience. In the first part of the paper we define the concepts of privacy and physicalism. In the second part we delineate two thought experiments in which two subjects undergo the same kind of conscious (...) experience in such a way that all the physical processes responsible for their experiences are numerically the same. Based on the thought experiments and their interpretations we present our argument for the inconsistency of the privacy of experience with physicalism in the third part of the paper. In the final part we defend our argumentation against some objections. (shrink)

The human mind is constituted by inner, subjective, private, first-person conscious experiences that cannot be measured with physical devices or observed from an external, objective, public, third-person perspective. The qualitative, phenomenal nature of conscious experiences also cannot be communicated to others in the form of a message composed of classical bits of information. Because in a classical world everything physical is observable and communicable, it is a daunting task to explain how an empirically unobservable, incommunicable consciousness could have any (...) physical substrates such as neurons composed of biochemical molecules, water, and electrolytes. The challenges encountered by classical physics are exemplified by a number of thought experiments including the inverted qualia argument, the private language argument, the beetle in the box argument and the knowledge argument. These thought experiments, however, do not imply that our consciousness is nonphysical and our introspective conscious testimonies are untrustworthy. The principles of classical physics have been superseded by modern quantum physics, which contains two fundamentally different kinds of physical objects: unobservable quantum state vectors, which define what physically exists, and quantum operators (observables), which define what can physically be observed. Identifying consciousness with the unobservable quantum information contained by quantum physical brain states allows for application of quantum information theorems to resolve possible paradoxes created by the inner privacy of conscious experiences, and explains how the observable brain is constructed by accessible bits of classical information that are bound by Holevo's theorem and extracted from the physically existing quantum brain upon measurement with physical devices.

Contrary to the widely-held view that our conscious states are necessarily private (in that only one person can ever experience them directly), in this paper I argue that it is possible for a person to directly experience the conscious states of another. This possibility removes an obstacle to thinking of conscious states as physical, since their apparent privacy makes them different from all other physical states. A separation can be made in the brain between our conscious mental representations and (...) the executive processes that manipulate them and are guided by them in planning and executing behaviour. I argue here that these executive processes are also largely responsible for producing our sense of self in the moment. Our conscious perceptual representations themselves reside primarily in the posterior portions of the brain's cortex, in the temporal and parietal lobes, while the executive processes reside primarily in the prefrontal lobes. We can imagine an experiment in which we sever the association fibers that connect the posterior regions with these prefrontal regions and, instead, connect the posterior regions to the prefrontal regions of another person. According to my hypothesis, this would produce in the latter person the direct experience of the conscious perceptual states of the first person. (shrink)

[This download contains the Table of Contents and Chapter 1]. I argue here that the claim that conscious states are private, in the sense that only one person can ever experience them directly, is false. There actually is a way to connect the brains of two people that would allow one to have direct experience of the other's conscious, e.g., perceptual states. This would allow, for instance, one person to see that the other had deviant color perception (which was masked (...) by correct linguistic practice). This could be achieved by connecting one person's set of executive processes (or cognitive control network) to the conscious perceptual states of the other. Chapter 5 contains an internalist physicalist account of color according to which colors exist only as brain states. Their function is to enable more precise causal interactions between the executive processes and the brain's perceptual systems. This in turn allows for more precise action: I can select the red apples and leave the green ones. (shrink)

According to conventional wisdom, the split-brain syndrome puts paid to the thesis that consciousness is necessarily unified. The aim of this paper is to challenge that view. I argue both that disunity models of the split-brain are highly problematic, and that there is much to recommend a model of the split-brain—the switch model—according to which split-brain patients retain a fully unified consciousness at all times. Although the task of examining the unity of consciousness through the lens of (...) the split-brain syndrome is not a new one—such projects date back to Nagel’s seminal paper on the topic—the time is ripe for a re-evaluation of the issues.

The unity of consciousness has so far been studied only as a relation holding among the many experiences of a single subject. I investigate whether this relation could hold between the experiences of distinct subjects, considering three major arguments against the possibility of such ‘between-subjects unity’. The first argument, based on the popular idea that unity implies subsumption by a composite experience, can be deflected by allowing for limited forms of ‘experience-sharing’, in which the same token experience belongs to (...) more than one subject. The second argument, based on the phenomenological claim that unified experiences have interdependent phenomenal characters, I show to rest on an equivocation. Finally, the third argument accuses between-subjects unity of being unimaginable, or more broadly a formal possibility corresponding to nothing we can make sense of. I argue that the familiar experience of perceptual co-presentation gives us an adequate phenomenological grasp on what between-subjects unity might be like. (shrink)

One sometimes believes a proposition without grasping it. For example, a complete achromat might believe that ripe tomatoes are red without grasping this proposition. My aim in this paper is to shed light on the difference between merely believing a proposition and grasping it. I focus on two possible theories of grasping: the inferential theory, which explains grasping in terms of inferential role, and the phenomenal theory, which explains grasping in terms of phenomenal consciousness. I argue that the phenomenal (...) theory is more plausible than the inferential theory. (shrink)

Recent work within such disparate research areas as the epistemology of perception, theories of well-being, animal and medical ethics, the philosophy of consciousness, and theories of understanding in philosophy of science and epistemology has featured disconnected discussions of what is arguably a single underlying question: What is the value of consciousness? The purpose of this paper is to review some of this work and place it within a unified theoretical framework that makes contributions (and contributors) from these disparate (...) areas more visible to one another.

This report highlights and explores five questions which arose from The Unity of Consciousness and Sensory Integration conference at Brown University in November of 2011: 1. What is the relationship between the unity of consciousness and sensory integration? 2. Are some of the basic units of consciousness multimodal? 3. How should we model the unity of consciousness? 4. Is the mechanism of sensory integration spatio-temporal? 5. How Should We Study Experience, Given Unity Relations?

What is dignity? My starting point is that dignity is one of those philosophical primitives that admit of no informative analysis. Nonetheless, I suggest, dignity might yield to indirect illumination when we consider the kind of experience we have (or rather find it fitting to have) in its presence. This experience, I claim, is what is sometimes known as recognition-respect. Through an examination of a neglected aspect of the phenomenology of recognition-respect, I argue that the possession of inner consciousness (...) is a precondition for the possession of dignity. The reason for this, I suggest, is that the ultimate privacy of the contents of our consciousness grounds a kind of inviolability characteristic of dignity. (shrink)

The aesthetic tradition has identified as paradigmatically sublime such objects as imposing mountains and intense storms, as well as monumental art. But the tradition also acknowledges less paradigmatic cases, including sometimes mathematical structures or abstract concepts. In this paper, we argue that there is also a case for considering phenomenal consciousness – the experiential quality of subjective awareness – as a sublime phenomenon. One appreciates this, we argue, when one is struck by (fitting) awe upon contemplating (a) the perplexing (...) existence of something like phenomenal consciousness in an otherwise completely material universe and (b) the role of consciousness in injecting meaning and value in an otherwise brutally factual reality.

It is intuitive that free action depends on consciousness in some way, since behavior that is unconsciously generated is widely regarded as un-free. But there is no clear consensus as to what such dependence comes to, in part because there is no clear consensus about either the cognitive role of consciousness or about the essential components of free action. I divide the space of possible views into four: the Constitution View (on which free actions metaphysically consist, at least (...) in part, in phenomenally conscious episodes of a special sort), the Causal-Dependence View (on which free actions are necessarily caused by conscious episodes), the Counterfactaul-Dependence View (on which free actions necessarily counterfactually dependent on conscious episodes of certain types), and the Independence View (on which there are no necessary dependence-relations that hold between free action and conscious episodes). After surveying recent empirical literature that purports to show that consciousness plays a smaller role in generating action than is usually supposed, I conclude that it is plausible that free action depends on consciousness in two ways. First, free action causally depends on consciousness control. Second, free action counterfactually depends on the agent's being responsive to certain reasons. (shrink)

Although the study of epileptic absence seizures has the potential to contribute a great deal to the scientific understanding of consciousness, this potential has yet to be fully exploited. There have been a number of insightful discussions of consciousness in the context of epileptic seizures, but the basic conceptual issues are still poorly understood and many empirical questions remain unexplored. In this paper I review a number of questions that are of interest to consciousness scientists and identify (...) ways in which the study of absence seizures might bear on their investigation.

This essay explores the nature of consciousness and its evolution, guiding the reader through the journey of early life forms and the development of human consciousness. It introduces the idea of a biological framework for a mathematical universe, suggesting that the mathematical structure of the universe is biological in nature. This theory proposes that living organisms and consciousness are a direct result of the universe's biologically-patterned processes, and that these processes can be observed and understood through physiological (...) patterns. The hidden biological patterns in our environment drive the creation and evolution of life and consciousness. (shrink)

Illusionism about phenomenal consciousness is the thesis that phenomenal consciousness does not exist, even though it seems to exist. This thesis is widely judged to be uniquely counterintuitive: the idea that consciousness is an illusion strikes most people as absurd, and seems almost impossible to contemplate in earnest. Defenders of illusionism should be able to explain the apparent absurdity of their own thesis, within their own framework. However, this is no trivial task: arguably, none of the illusionist (...) theories currently on the market is able to do this. I present a new theory of phenomenal introspection and argue that it might deal with the task at hand. (shrink)

The term action of consciousness is used to refer to an influence, such as psychokinesis or free will, that produces an effect on matter that is correlated to mental intention, but not completely determined by physical conditions. Such an action could not conserve energy. But in that case, one wonders why, when highly accurate measurements are done, occasions of non-conserved energy (generated perhaps by unconscious PK) are not detected. A possible explanation is that actions of consciousness take place (...) within the limits of the uncertainty principle. Two models are reviewed that, using the latter assumption, propose that consciousness can originate an action potential in the brain. One (that of Eccles) uses the latter assumption only, and the other (that of Burns) additionally assumes that consciousness acts, within those limits, by ordering quantum fluctuations. (shrink)

As for most measurement procedures in the course of their development, measures of consciousness face the problem of coordination, i.e., the problem of knowing whether a measurement procedure actually measures what it is intended to measure. I focus on the case of the Perceptual Awareness Scale to illustrate how ignoring this problem leads to ambiguous interpretations of subjective reports in consciousness science. In turn, I show that empirical results based on this measurement procedure might be systematically misinterpreted.

Consciousness may not only be a problem how to know the brain but also a problem how to understand what known. Understanding is always an ontological system created as the explanation of what known by us. And, if all brains, including human brains, may be defined as the mind, consciousness must be part of our understanding of the mind. The author argues that no mind may exist if not be a life or lives, no life may exist if (...) not be a mind or a part of it, and, if it is the mind that needs to be explained, it must finally and fundamentally be explained as a life or a living system. An ontological definition of life is proposed first in this article, which is also applicable to fields such as physics, biology, psychology, and sociology. Based on an analysis of two kinds of lives and their relationship with matter and energy, a living system is modeled as the organization of two system relations, which explains not only consciousness but also wakefulness, emotion, intelligence, language and mind-body relationship. And finally, a semantic theory is reached, which takes lives as the only meaning of all symmetrical and conservative changes, such as the location changes or form changes of consciousness, or the state changes of memories. The concept of life, the model of living systems and the semantic theory together provide a framework for us to understand what and how consciousness is, why there is consciousness, where and when consciousness occurs.

If one lives in a city and wants to be by oneself or have a private conversation with someone else, there are two ways to set about it: either one finds a place of solitude, such as one’s bedroom, or one finds a place crowded enough, public enough, that attention to each person dilutes so much so as to resemble a deserted refuge. Often, one can get more privacy in public places than in the most private of spaces. The (...) home is not always the ideal place to find privacy. Neighbours snoop, children ask questions, and family members judge. When the home suffocates privacy, the only escape is to go out, to the coffee shop, the public square. For centuries, city streets have been the true refuges of the solitaries, the overwhelmed, and the underprivileged. -/- Yet time and again we hear people arguing that we do not have any claim to privacy while on the streets because they are part of the so-called public sphere. The main objective of this chapter is to argue that privacy belongs as much in the streets as it does in the home. (shrink)

This article introduces and defends the “pathological complexity thesis” as a hypothesis about the evolutionary origins of minimal consciousness, or sentience, that connects the study of animal consciousness closely with work in behavioral ecology and evolutionary biology. I argue that consciousness is an adaptive solution to a design problem that led to the extinction of complex multicellular animal life following the Avalon explosion and that was subsequently solved during the Cambrian explosion. This is the economic trade-off problem (...) of having to deal with a complex body with high degrees of freedom, what I call “pathological complexity.” By modeling the explosion of this computational complexity using the resources of state-based behavioral and life history theory we will be able to provide an evolutionary bottom-up framework to make sense of subjective experience and its function in nature by paying close attention to the ecological lifestyles of different animals.

The principal aim of the thesis is to develop a developmental account of conscious experience. In this account, the objective is to understand and explain the phenomenal experience of newborns and pre-linguistic infants. The question that guides the investigation concerns the phenomenality of babies' experiences: what is it like to be a baby? There are some crucial philosophical issues that any account of the nature of infant consciousness must face: the ontology of early conscious states; the epistemic status of (...) infants' experiences; the content of infants' experiences. The thesis addresses how we evolve as conscious beings from early states of life until we become full self-conscious beings who are morally responsible for our actions. The thesis involves four chapters. The first chapter explores phenomenal consciousness in newborns, first addressing the epistemological and methodological problems, and then arguing that newborns are phenomenally conscious and have a variety of phenomenal experiences. The second chapter addresses representation in newborns, claiming that their conscious experiences represent the world and discussing the consequences for representationalism. The third chapter focuses on the sense of agency, arguing that infants have a sense of agency and a sort of self-consciousness. The fourth chapter discusses moral agency, focusing mainly on the role of empathy. (shrink)

We generally accept that medicine’s conceptual and ethical foundations are grounded in recognition of personhood. With patients in vegetative state, however, we’ve understood that the ethical implications of phenomenal consciousness are distinct from those of personhood. This suggests a need to reconsider medicine’s foundations. What is the role for recognition of consciousness (rather than personhood) in grounding the moral value of medicine and the specific demands of clinical ethics? I suggest that, according to holism, the moral value of (...) medicine is secured when conscious states are recognized in everyday medical science. Moreover, consciousness fully motivates traditional principles of clinical ethics if we understand respect for autonomy as respect for the dominion of an experiencer in the private, inescapable realm of bodily experience. When medicine’s foundations are grounded in recognition of consciousness, we understand how patients fully command respect even when they lack capacity to exercise their bodily dominion through decision-making.

According to proponents of the extended mind, bio-external resources, such as a notebook or a smartphone, are candidate parts of the cognitive and mental machinery that realises cognitive states and processes. The present chapter discusses three areas of ethical concern associated with the extended mind, namely mental privacy, mental manipulation, and agency. We also examine the ethics of the extended mind from the standpoint of three general normative frameworks, namely, consequentialism, deontology, and virtue ethics.

An extended examination of Libet's works led to a comprehensive reinterpretation of his results. According to this reinterpretation, the Minimum Train Duration of electrical brain stimulation should be considered as the time needed to create a brain stimulus efficient for producing conscious sensation and not as a basis for inferring the latency for conscious sensation of peripheral origin. Latency for conscious sensation with brain stimulation may occurafterthe Minimum Train Duration. Backward masking with cortical stimuli suggests a 125-300 ms minimum value (...) for the latency for conscious sensation of threshold skin stimuli. Backward enhancement is not suitable for inferring this latency. For determining temporal relations between stimuli that correspond to subjects' reports, theendof cerebral Minimum Train Duration should be used as reference, rather than its onset. Results of coupling peripheral and cortical stimuli are explained by a latency after the cortical Minimum Train Duration, having roughly the same duration as the latency for supraliminal skin stimuli. Results of coupling peripheral stimuli and stimuli to medial lemniscus (LM) are explained by a shorter LM latency and/or a longer peripheral latency. This interpretation suggests a 230 ms minimum value for the latency for conscious sensation of somatosensory near-threshold stimuli. The backward referral hypothesis, as formulated by Libet, should not be retained. Long readiness potentials preceding spontaneous conscious or nonconscious movements suggest that both kinds of movement are nonconsciously initiated. The validity of Libet's measures of W and M moments (Libet et al., 1983a) is questionable due to problems involving latencies, training, and introspective distinction of W and M. Veto of intended actions may be initially nonconscious but dependent on conscious awareness. (shrink)

There is a strong intuition that a zombie’s life is never good or bad for the zombie. This suggests that consciousness has a special role in making life good or bad for the one who lives it. What explains this? In this paper, I consider five possible explanations of the intuition that a zombie’s life is never worth living, plus the option of rejecting the intuition. I point out the considerable costs of each option, though making clear which option (...) strikes me as least problematic. (shrink)

Locke has been accused of failing to have a coherent understanding of consciousness, since it can be identical neither to reflection nor to ordinary perception without contradicting other important commitments. I argue that the account of consciousness is coherent once we see that, for Locke, perceptions of ideas are complex mental acts and that consciousness can be seen as a special kind of self-referential mental state internal to any perception of an idea.

In this paper we describe a few interrelated issues for validating theories that posit levels of consciousness. First, validating levels of consciousness requires consensus about the ordering of conscious states, which cannot be easily achieved. This problem is particularly severe if we believe conscious states can be irreducibly smeared over time. Second, the relationship between conscious states is probably sometimes intransitive, which means levels of consciousness will not be amenable to a single continuous measure. Finally, even if (...) a multidimensional approach to levels of consciousness is adopted, we argue that there are further problems for its validation. (shrink)

Abstract: Nietzsche’s famously wrote that “consciousness is a surface” (EH, Why I am so clever, 9: 97). The aim of this paper is to make sense of this quite puzzling contention—Superficiality, for short. In doing this, I shall focus on two further claims—both to be found in Gay Science 354—which I take to substantiate Nietzsche’s endorsement of Superficiality. The first claim is that consciousness is superfluous—which I call the “superfluousness claim” (SC). The second claim is that consciousness (...) is the source of some deep falsification—which I call the “falsification claim” (FC). I shall start by considering Nietzsche’s notion of consciousness. Here, I shall argue that the kind of consciousness he is concerned with is in fact self-consciousness and that he put forward a higher-order theory of it. Then, I shall address the two claims. Regarding (FC), my proposal will be that, according to Nietzsche, the content of (self-)conscious mental states is falsified in virtue of its being articulated propositionally. Regarding (SC), I shall claim that it is best read as a weak version of epiphenomenalism about conscious causation. In addressing both points, I shall discuss in particular the influential reading of Nietzsche’s theory of consciousness offered by Katsafanas (2005). (shrink)

The neurophilosophy of consciousness brings neuroscience to bear on philosophical issues concerning phenomenal consciousness, especially issues concerning what makes mental states conscious, what it is that we are conscious of, and the nature of the phenomenal character of conscious states. Here attention is given largely to phenomenal consciousness as it arises in vision. The relevant neuroscience concerns not only neurophysiological and neuroanatomical data, but also computational models of neural networks. The neurophilosophical theories that bring such data to (...) bear on the core philosophical issues of phenomenal conscious construe consciousness largely in terms of representations in neural networks associated with certain processes of attention and memory.

The physical sciences, as generally understood, are disciplines concerned with the characteristics and behavior of physical objects and states. What is evident about the current condition of consciousness is that: 1) It has no identified physical states; 2) There is no generally accepted vocabulary of its functioning, or its participant entities; and 3) No ‘normal science’ operative structure upon which a community of scientists agree. The reasons are that consciousness is a prescientific concept persisting because there is no (...) adequate physicalist theory to replace it, and because biology operates in a way ‘invisible’ to assumed mental processes and vocabulary. What is required is a plausible theory built on a biophysical base. A theory is being developed: it is termed the _theory of brain-sign_. Brain-sign replaces consciousness as an evolved neural operation in which brains communicate with each other in the collective action of organisms, so addressing the limitations of being an isolated individual. It depends upon neural signification, in this case of the organisms’ immediate _causal orientation_ towards the world. Thus, multiple organisms are linked as one biophysical operation. Signs are biologically ubiquitous and inherently physical. Organisms are not subjective agents with transcendent powers acting in a perceivable world, but evolved organic objects with the ability to cooperate as one overarching biological process. It is anticipated this theoretical operation and vocabulary will explain brain function, which mind fails to do. It accounts for science from both its neural origins and its communal nature. ER -.

This is an excerpt of a report that highlights and explores five questions which arose from The Unity of Consciousness and Sensory Integration conference at Brown University in November of 2011. This portion of the report explores the question: How should we model the unity of consciousness?

The aim of this paper is to provide an interpretation for Sartre’s account of the unity of consciousness in The Transcendence of the Ego. I will argue that it is only once The Transcendence of the Ego is read alongside other texts written around the same time, such as The Imaginary, that we can understand how Sartre believes it is possible for consciousness to be unified without an I. I begin by setting out the Kantian context that Sartre (...) develops for his views, before looking at Sartre’s arguments themselves. I then turn to some of the difficulties other readers have encountered with making sense of the arguments of the Transcendence of the Ego. I argue that it is only in relation to Sartre’s account of what he calls the illusion of immanence in The Imaginary, that we can make sense of Sartre’s account of consciousness, before reconstructing what I take to be Sartre’s position drawing on Sartre’s references to Bergson and Spinoza.

Beginning with the paradoxes of zombie twins, we present an argument that dualism is both true and false. We show that avoiding this contradiction is impossible. Our diagnosis is that consciousness itself engenders this contradiction by producing contradictory points of view. This result has a large effect on the realism/anti-realism debate, namely, it suggests that this debate is intractable, and furthermore, it explains why this debate is intractable. We close with some comments on what our results mean for metaphysics (...) and philosophy, in general. (shrink)

Theories of the mind have been celebrating their new-found freedom to study consciousness. Earlier this century, when the methodology of psychology was still under the influence of behaviourism—the view that psychology can only study observable behaviour—the ‘superstition and magic’ of consciousness (in John Watson’s words) was not the proper object of scientific investigation. But now, there are respectable journals devoted to the study of consciousness, there are international interdisciplinary conferences on the subject, and some of the world’s (...) leading scientists—notably Roger Penrose and Francis Crick—have stepped in to have their say about the nature of consciousness.

This paper explores the elusive dialectic between concentration and forgetfulness, consciousness and unconsciousness in spontaneous artistic creation favoured by artists and advocated by critics in Chinese art history, by examining texts on painting and tracing back to ancient Daoist philosophical ideas, in a comparison with Kantian and post-Kantian aesthetics. Although artistic spontaneity in classical Chinese aesthetics seems to share similarities with Kant’s account of spontaneity in the art of genius, the emphasis on unconsciousness is valued by classical Chinese artists (...) and critics inspired by the Daoist idea of ‘Wu Wei’ (acting without conscious intention or effort). As the Qing painter Wang Yuanqi (1642–1715) claimed when admitting his failure to copy the Yuan master Ni Zan (1301–1374), Ni Zan’s success in natural and untrammelled expression lies ‘in between having an intention and not having one’. A similar idea about the dialectic of consciousness and unconsciousness in artistic spontaneity was suggested by Heinrich von Kleist’s On the Marionette Theatre (1880), which demonstrated that while self-consciousness might disturb and hinder the naturalness of artistic expression and thus encourage affectation, it does not mean that there is no role for consciousness. Although the views on unconsciousness in art and the co-play of consciousness and unconscious in artistic creation by Schelling, Schiller, Goethe, and even Nietzsche might get inspirations from Kant’s hidden view of the unconscious, Kant’s emphasis on the harmonious cooperation between imagination and understanding disguises his inexplicit idea of the unconscious. This paper will demonstrate that while in both Classical Chinese and European cultural contexts, artists, critics and philosophers talk about the same elusive relation, the philosophical explanations of the same phenomenon are essentially distinctive.

The problem of consciousness is taken to concern items which are internal to the mind, and phenomenal, subjective, and private. Understanding the notion of innerness in this enables us to understand the rest in physical terms.

Does consciousness survive bodily death? This question remains a profound, perennial mystery. Although scientific studies have focused on out-of-body experiences (OBEs) and near-death experiences (NDEs), there is scant evidence to support the claim that consciousness survives death. Many speculative theories state that consciousness moves through various afterlife realities. Tantalizing clues are found in world religion, esoteric philosophy, extrasensory perception, hypnotic regression, and scientific experimentation. At the present time, there is an abundance of theoretical scholarly discourse on the (...) topic of “survival.” After 60 years of NDE research, common ground has been established from NDEers’ anecdotal evidence and perceptual experiences.

Why consciousness cannot be explained scientifically (causally) and requires an approach that incudes agency.

Some time ago, in an article for the Journal of Consciousness Studies, David Chalmers challenged his peers to identify the ingredient missing from our current theories of consciousness, the absence of which prevents us from solving the 'hard' problem and forces us to make do with nonreductive theories. Here I respond to this challenge. I suggest that consciousness is a metaphysical problem and as such can be solved only within a global metaphysical theory. Such a theory would (...) look very like the information theory proposed by Chalmers, but with the addition of an extra phenomenon that would allow it to become fundamental. (shrink)

Peter Godfrey-Smith’s Metazoa and Joseph LeDoux’s The Deep History of Ourselves present radically different big pictures regarding the nature, evolution and distribution of consciousness in animals. In this essay review, I discuss the motivations behind these big pictures and try to steer a course between them.

The critic of substance immobility through negation constitutes the starting point of the ‘voyage of discovery’ of Hegel’s Phänomenologie des Geistes, in which mind and body experiences are considered in terms of mutual recognition, without denying the subjectivity. In this article I am discussing some aspects of Hegel’s philosophy of spirit after Nietzsche’s ‘experimentalism’ and Dennett’s theory of mind, in order to articulate, through Bergson, two fundamental reasons. The first concerns the subject and the dramatic awareness of its constitutional temporality (...) and, at the same time, the possibility to transcend the limit of ‘here’ and ‘now’. On this basis, the second regards the indefensibility of nihilism, because, thanks to consciousness and its continuous activity, the temporal subject, from Hegel to Bergson, persists as a ‘dark side’, in which a constant ‘overcoming’ (élan) of an implicitly normative and essentially social practice takes place.

The Evolution of the Sensitive Soul is a landmark attempt to make progress on the problem of animal consciousness. Ginsburg and Jablonka propose a general cognitive marker of the presence of consciousness: Unlimited Associative Learning. They use this marker to defend a generous view about the distribution of consciousness in the natural world, on which a capacity for conscious experience is common to all vertebrates, many arthropods and some cephalopod molluscs. They use this inferred distribution to defend (...) a view about the evolution of consciousness, on which it has evolved at least three times, first evolved at around the time of the Cambrian explosion, and was in fact the driving force behind that explosion. In this essay review, I reflect critically on the book’s central idea: the proposal that Unlimited Associative Learning provides a general marker of consciousness. (shrink)

Perception enables us to think demonstrative thoughts about the world around us, but what must perception be like in order to play this role? Does perception enable demonstrative thought only if it is conscious? This paper examines three accounts of the role of consciousness in demonstrative thought, which agree that consciousness is essential for demonstrative thought, but disagree about why it is. First, I consider and reject the accounts proposed by Gareth Evans in The Varieties of Reference and (...) by John Campbell in Reference and Consciousness before offering an alternative proposal of my own. My proposal is that consciousness plays an essential epistemic role in explaining the capacity for demonstrative thought about an object by enabling the subject to form immediately justified beliefs about the object.

Not only Descartes, but also any theist thinker who faces the problem of consciousness, will face a problem with closure of the physical. In other words, there could not be a theory of consciousness that is compatible both with classical theism and closure of the physical. Therefore, the best strategy for theist thinkers is to follow the fallacy of the closure of the physical. There would be options such as the new forms of interactionist dualism and panpsychism.

The Significance Argument (SA) for the irreducibility of consciousness is based on a series of new puzzle-cases that I call multiple candidate cases. In these cases, there is a multiplicity of physical-functional properties or relations that are candidates to be identified with the sensible qualities and our consciousness of them, where those candidates are not significantly different. I will argue that these cases show that reductive materialists cannot accommodate the various ways in which consciousness is significant and (...) must allow massive vagueness in conscious experience. I also will argue that a nonreductive theory of the conscious-of relation can easily provide a very satisfying, unified explanation of the ways in which this relation is significant. (shrink)

This goal of this thesis in the philosophy of nature is to move us closer towards a true biological science of consciousness in which the evolutionary origin, function, and phylogenetic diversity of consciousness are moved from the field’s periphery of investigations to its very centre. Rather than applying theories of consciousness built top-down on the human case to other animals, I argue that we require an evolutionary bottomup approach that begins with the very origins of subjective experience (...) in order to make sense of the place of mind in nature. To achieve this goal, I introduce and defend the pathological complexity thesis as both a framework for the scientific investigation of consciousness and as a lifemind continuity thesis about the origins and function of consciousness.

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)

In recent years, the science and the philosophy of consciousness has seen growing interest in structural questions about consciousness. This is the Editorial Introduction for a special volume for Philosophy and the Mind Sciences on “Structuralism in Consciousness Studies.”.

According to the standard view in philosophy, intentionality is the mark of genuine action. In psychology, human cognition and agency are now widely explained in terms of the workings of two distinct systems (or types of processes), and intentionality is not a central notion in this dual-system theory. Further, it is often claimed, in psychology, that most human actions are automatic, rather than consciously controlled. This raises pressing questions. Does the dual-system theory preserve the philosophical account of intentional action? How (...) much of our behavior is intentional according to this view? And what is the role of consciousness? I will propose here a revised account of intentional action within the dual-system framework, and we will see that most of our behavior can qualify as intentional, even if most of it is automatic. An important lesson will be that philosophical accounts of intentional action need to pay more attention to the role of consciousness in action. (shrink)
