The Conscious Brain brings neuroscientific evidence to bear on enduring philosophical questions. Major philosophical and scientific theories of consciousness are surveyed, challenged, and extended.

It is an important feature of creatures like us that our various motivations compete for control over our behaviour, including mental behaviour such as imagining and attending. In large part, this competition is adjudicated by the stimulation of affect — the intrinsically pleasant or unpleasant aspects of experience. In this paper I argue that the motivation-affect system controls a sub-type of attention called 'alerting attention' to bring various goals and stimuli to consciousness and thereby prioritize those contents for action. (...) This view allows me to flesh out the global workspace theory of consciousness, as well as some of the phenomenal characteristics of conscious experience. (shrink)

It is well known that the nature of consciousness is elusive, and that attempts to understand it generate problems in metaphysics, philosophy of mind, psychology, and neuroscience. Less appreciated are the important – even if still elusive – connections between consciousness and issues in ethics. In this chapter we consider three such connections. First, we consider the relevance of consciousness for questions surrounding an entity’s moral status. Second, we consider the relevance of consciousness for questions surrounding (...) moral responsibility for action. Third, we consider the relevance of consciousness for the acquisition of moral knowledge. (shrink)

In this paper I aim to defend David Rosenthal's higher-order thought theory of consciousness against a prominent objection. The central claim of HOT theory is that a mental state is conscious only if one has the HOT that one is in that state. In broad outline, the objection is that HOT theory is unable to account for cases where the relevant HOTs are false. I consider two variants of the objection, corresponding to two kinds of false HOT: those that (...) merely misrepresent their targets, and those which lack targets altogether. I argue that a satisfactory response to the objection involving the latter, targetless, kind of HOTs, is to deny that one is in any conscious state in virtue of such HOTs. I show how this response is superior to Rosenthal's own response, and defend it against objections. I also argue that my account of targetless HOT cases may be generalized to cover cases of misrepresenting HOTs. (shrink)

Colin McGinn presents his latest work on consciousness in ten interlinked papers, four of them previously unpublished. He extends and deepens his controversial solution to the mind-body problem, defending the view that consciousness is both ontologically unproblematic and epistemologically impenetrable. He also investigates the basis of our knowledge that there is a mind-body problem, and the bearing of this on attempted solutions. McGinn goes on to discuss the status of first-person authority, the possibility of atomism with respect to (...) consciousness, extreme dualism, and the role of non-existent objects in constituting intentionality. He argues that traditional claims about our knowledge of our own mind and of the external world can be inverted; that atomism about the conscious mind might turn out to be true; that dualism is more credible the more extreme it is; and that all intentionality involves non-existent objects. These are all surprising positions, but he contends that what the philosophy of mind needs now is 'methodological radicalism' - a willingness to consider new and seemingly extravagant ideas.

What is consciousness? How does it arise? And why does it exist? We take our experience of being in the world for granted. But the very existence of consciousness raises profound questions: Why would any collection of matter in the universe be conscious? How are we able to think about this? And why should we? In this wonderfully accessible book, Annaka Harris guides us through the evolving definitions, philosophies, and scientific findings that probe our limited understanding of (...) class='Hi'>consciousness. Where does it reside, and what gives rise to it? Could it be an illusion, or a universal property of all matter? As we try to understand consciousness, we must grapple with how to define it and, in the age of artificial intelligence, who or what might possess it. Conscious offers lively and challenging arguments that alter our ideas about consciousness--allowing us to think freely about it for ourselves, if indeed we can." -- book jacket. (shrink)

A pioneering work in the philosophy of mind, Content and Consciousness brings together the approaches of philosophers and scientists to the mind--a connection that must occur if genuine analysis of the mind is to be made. This unified approach permits the most forbiddingly mysterious mental phenomenon--consciousness--to be broken down into several distinct phenomena, and these are each given a foundation in the physical activity of the brain. This paperback edition contains a preface placing the book in the context (...) of recent work in the area. (shrink)

Could a sufficiently detailed computer simulation of consciousness replicate consciousness? In other words, is performing the right computations sufficient for artificial consciousness? Or will there remain a difference between simulating and being a conscious system, because the right computations must be implemented in the right way? From the perspective of Karl Friston's free energy principle, self-organising systems (such as living organisms) share a set of properties that could be realised in artificial systems, but are not instantiated by (...) computers with a classical (von Neumann) architecture. I argue that at least one of these properties, viz. a certain kind of causal flow, can be used to draw a distinction between systems that merely simulate, and those that actually replicate consciousness. Since this property is instantiated by all systems that conform to the free energy principle (not just conscious beings), the account on offer here can be extended to draw a distinction between simulating and being a certain type of system, more generally. In particular, this may inform meta-ethical accounts of artificial moral status and artificial moral agency. (shrink)

What is the role of consciousness in our mental lives? Declan Smithies argues here that consciousness is essential to explaining how we can acquire knowledge and justified belief about ourselves and the world around us. On this view, unconscious beings cannot form justified beliefs and so they cannot know anything at all. Consciousness is the ultimate basis of all knowledge and epistemic justification.

Does consciousness have non-instrumental aesthetic value? This paper answers this question affirmatively by arguing that consciousness is sublime. The argument consists of three premises. (1) An awe experience of an object provides prima facie justification to believe that the object is sublime. (2) I have an awe experience about consciousness through introspecting three features of consciousness, namely the mystery of consciousness, the connection between consciousness and well-being, and the phenomenological complexity of consciousness. (3) (...) There is no good defeater of the justificatory force of my feeling of awe for the sublime of consciousness. To defend the third premise, I argue against two potential defeaters: The first is that most people do not regard consciousness as sublime. The second is that there do not seem to be physical properties that can ground the sublimity of consciousness. I conclude by emphasizing an important ethical implication of the thesis that consciousness is sublime, namely that it explains why even conscious subjects who cannot have valenced experiences deserve moral consideration.

This paper distinguishes between implicit self-related information and explicit self-representation and argues that the latter is required for self-consciousness. It is further argued that self-consciousness requires an awareness of other minds and that this awareness develops over the course of an increasingly complex perspectival differentiation, during which information about self and other that is implicit in early forms of social interaction becomes redescribed into an explicit format.

Consciousness is explored as a living stream of lucid experience composed of the essence of the moments of our lives. Grounded in Ken Wilber's model, consciousness is explained from many points of view: its historical evolution, its growth in the individual, its mystical dimensions, and the meaning of enlightenment"--Provided by publisher.

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible , and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and arguments (...) developed earlier to defend a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

What does the fact that we feel shame tell us about the nature of self? Does shame testify to the presence of a self-concept, a self-ideal, and a capacity for critical self-assessment, or does it rather, as some have suggested, point to the fact that the self is in part socially constructed? Should shame primarily be classified as a self-conscious emotion, is it rather a distinct social emotion, or might this forced alternative be misguided? In the chapter, I contrast certain (...) prevalent cognitivist accounts of shame with different proposals that can be found in the phenomenological tradition and ultimately argue that prototypical forms of shame provide vivid examples of other-mediated forms of self-experience.

This paper examines two objections by Colin McGinn to panexperientialist metaphysics as a solution to the mind-body problem. It begins by briefly stating how the `ontological problem' of the mind-body relationship is central to the philosophy of mind, summarizes the difficulties with dualism and materialism, and outlines the main tenets of panexperientialism. Panexperientialists, such as David Ray Griffin, claim that theirs is one approach to solving the mind-body problem which does not get stuck in accounting for interaction nor in the (...) difficulties with emergentism and epiphenomenalism . McGinn attacks panexperientialism on two fronts: the Whiteheadian distinction between `consciousness' and `experience' and the notion of consciousness emerging from `non-conscious experience'; and the implicit `absurdities' inherent in the notion of experience and self-agency in the fundamental particles of physics. Griffin's defence fails to satisfactorily address challenge ; though a model is presented by the author which may offer panexperientialism a way out. McGinn's challenge is an attempted reductio which Griffin rejects: that panexperientialism contradicts the evidence of modern quantum- relativistic physics. The author's analysis of the opposing positions shows that both philosophers are arguing from incompatible `geometries of discourse' and radically inconsistent metaphysical assumptions. The paper concludes that a resolution of both the mind-body problem in general, and of the McGinn-Griffin dispute in particular, needs to involve an epistemological shift to include extra-rational ways of knowing.

Consciousness is connected with the fact that a subject is aware and open to the manifestation of whatever appears. Existence, by contrast, is used to express the fact that something is given in experience, is present, or is real. Usually, the two notions are taken to be somehow related. This chapter suggests that existence is at best introduced as a metaphysical (or meta-experiential) concept that inevitably escapes the domain of conscious experience. In order to illustrate this claim, two case (...) studies are considered. The first case is provided by Descartes’s famous treatment of consciousness and existence in his Meditations on First Philosophy. The second case is meant to contrast the Cartesian approach by taking the opposite route, as delineated by Emanuele Severino (1929–2020) in his ‘fundamental ontology’. (shrink)

This text centers on the analysis of pure consciousness as found in Advaita Vedanta, one of the main schools of Indian philosophy. Written lucidely and clearly, it reveals the depth and implications of Indian metaphysics and argument.

Realism about consciousness conjoins a claim that consciousness exists with a claim that the existence is independent in some interesting sense. Consciousness realism so conceived may thus be opposed by a variety of anti-realisms, distinguished from each other by denying the first, the second, or both of the realist’s defining claims. I argue that Dennett’s view of consciousness is best read as an anti-realism that affirms the existence of consciousness while denying an important independence claim.

Let a smooth experience be an experience with perfectly gradual changes in phenomenal character. Consider, as examples, your visual experience of a blue sky or your auditory experience of a rising pitch. Do the phenomenal characters of smooth experiences have continuous or discrete structures? If we appeal merely to introspection, then it may seem that we should think that smooth experiences are continuous. This paper (1) uses formal tools to clarify what it means to say that an experience is continuous (...) or discrete, and (2) develops a discrete model of the phenomenal characters of smooth experiences. As a result, I'll argue that introspection leaves open whether smooth experiences are continuous or discrete. Yet I’ll also argue—perhaps surprisingly—that the discrete theory may better fit our introspective evidence. (shrink)

Intuitively, there is a close link between moral status and phenomenal consciousness. Taking the link seriously can serve as the basis of a proposal that appears to have a surprising number of theoretical benefits. This proposal is the moral option, according to which moral status is partly determinative of phenomenal consciousness, and phenomenal consciousness is sufficient for possession of a moral property I refer to as “moral status.” I argue for this view on the basis of its (...) ability to shed light on the distribution problem of determining which systems are phenomenally conscious. I explicate it by drawing on a theory of attributions of phenomenal consciousness, and considering its relationship to positions on the metaphysics of consciousness. I defend it against a series of objections, including three based on previous theories of the link between phenomenal consciousness and moral status. The moral option should, in my view, be a serious contender among theories of phenomenal consciousness. (shrink)

In this book Daniel Wegner offers a novel understanding of the relation of consciousness, the will, and our intentional and voluntary actions. Wegner claims that our experience and common sense view according to which we can influence our behavior roughly the way we experience that we do it is an illusion.

This chapter discusses the main types of so-called ’subjective measures of consciousness’ used in current-day science of consciousness. After explaining the key worry about such measures, namely the problem of an ever-present response bias, I discuss the question of whether subjective measures of consciousness are introspective. I show that there is no clear answer to this question, as proponents of subjective measures do not employ a worked-out notion of subjective access. In turn, this makes the problem of (...) response bias less tractable than it might otherwise be. (shrink)

Qualitative consciousness is conscious experience marked by the presence of sensory qualities, like the experienced painfulness of having a piano dropped on your foot, or the consciousness of seeing the brilliant reds and oranges of a sunset. Over his career, philosopher David Rosenthal has defended an influential theoretical approach to explaining qualitative consciousness. This approach involves the development of two theories – the higher-order thought theory of mental state consciousness and the quality space theory of sensory (...) quality. If the problem of explaining qualitative consciousness is divided into two more manageable pieces, the door opens to a satisfying explanation of what is seen by some to be an intractable explanatory puzzle. This interdisciplinary collection develops, criticizes, and expands upon themes inspired by Rosenthal's work. The result is an exciting collection of new essays by philosophers and scientists, which will be of interest to all those engaged in consciousness studies. (shrink)

As a tactic for preventing an enquiry into attention’s relationship to consciousness from lapsing into ill-definition, this chapter treats ‘attention’ as a term defined by the role that is assigned to it in our explanations of empirically established psychological phenomena (especially those involving the modulation of reaction times). It reviews evidence showing that such modulations are associated with processing that stands in various relations to consciousness. The psychological phenomena that explain these modulations cannot be identified with the causes (...) of consciousness. Nor do they operate exclusively within the field of conscious awareness. If the explanation of these phenomena is to cast explanatory light on how and when consciousness occurs, it will need to do so in the context of some more complex explanatory theory. (shrink)

How does your mind work? How does your brain give rise to your mind? These are questions that all of us have wondered about at some point in our lives, if only because everything that we know is experienced in our minds. They are also very hard questions to answer. After all, how can a mind understand itself? How can you understand something as complex as the tool that is being used to understand it? This book provides an introductory and (...) self-contained description of some of the exciting answers to these questions that modern theories of mind and brain have recently proposed. Stephen Grossberg is broadly acknowledged to be the most important pioneer and current research leader who has, for the past 50 years, modelled how brains give rise to minds, notably how neural circuits in multiple brain regions interact together to generate psychological functions. This research has led to a unified understanding of how, where, and why our brains can consciously see, hear, feel, and know about the world, and effectively plan and act within it. The work embodies revolutionary Principia of Mind that clarify how autonomous adaptive intelligence is achieved. It provides mechanistic explanations of multiple mental disorders, including symptoms of Alzheimer's disease, autism, amnesia, and sleep disorders; biological bases of morality and religion, including why our brains are biased towards the good so that values are not purely relative; perplexing aspects of the human condition, including why many decisions are irrational and self-defeating despite evolution's selection of adaptive behaviors; and solutions to large-scale problems in machine learning, technology, and Artificial Intelligence that provide a blueprint for autonomously intelligent algorithms and robots. Because brains embody a universal developmental code, unifying insights also emerge about shared laws that are found in all living cellular tissues, from the most primitive to the most advanced, notably how the laws governing networks of interacting cells support developmental and learning processes in all species. The fundamental brain design principles of complementarity, uncertainty, and resonance that Grossberg has discovered also reflect laws of the physical world with which our brains ceaselessly interact, and which enable our brains to incrementally learn to understand those laws, thereby enabling humans to understand the world scientifically. Accessibly written, and lavishly illustrated, Conscious Mind/Resonant Brain is the magnum opus of one of the most influential scientists of the past 50 years, and will appeal to a broad readership across the sciences and humanities.
