Jonardon Ganeri presents a ground-breaking study of selfhood, drawing on Indian theories of consciousness and mind.

In Consciousness and Persons: Unity and Identity, Michael Tye takes on the thorny issue of the unity of consciousness and answers these important questions: What exactly is the unity of consciousness? Can a single person have a divided consciousness? What is a single person? Tye argues that unity is a fundamental part of human consciousness -- something so basic to everyday experience that it is easy to overlook. For example, when we hear the sound of waves crashing on a beach (...) and at the same time see a red warning flag, there is an overall unity to our experience; the sound and the red shape are presented together in our consciousness. Similarly, when we undergo a succession of thoughts as we think something through, there is an experience of succession that unifies the thoughts into a conscious whole. But, Tye shows, consciousness is not always unified. Split-brain subjects, whose corpus callosum has been severed, are usually taken to have a divided or disunified consciousness. Their behavior in certain situations implies that they have lost the unity normal human subjects take for granted; it is sometimes even supposed that a split-brain subject is really two persons.Tye begins his account by proposing an account of the unity of experience at a single time; this account is extended over the succeeding chapters to cover bodily sensations at a single time and perceptual experience, bodily sensations, conscious thoughts, and felt moods at a single time. Tye follows these chapters with a discussion of the unity of experience through time. Turning to the split-brain phenomenon, he proposes an account of the mental life of split-brain subjects and argues that certain facts about these subjects offer support for his theory of unity. Finally, addressing the topic of the nature of persons and personal identity, Tye finds the two great historical accounts -- the ego theory and the bundle theory -- lacking and he makes an alternative proposal. He includes an appendix on the general representational approach to consciousness and its many varieties, because of the relevance of representationalism to the theory of unity being adanced.

There is much to admire in this book. It is written in a pleasingly straightforward style, and offers insight on a wide range of important issues.

While Derek Parfit is aware that his reductionism about persons is anticipated in early Buddhism and Abhidharma, he has not explored that tradition for any clues it might yield concerning the consequences of adopting the position. In this essay, the tradition is used to construct a taxonomy of possible views about persons, and then examine the meta-physical commitments that Buddhist reductionists claim are entailed by their view. While these turn out to be significant, it is argued here that this is (...) a price a reductionist should be prepared to pay. (shrink)

The original data reported by Benjamin Libet and colleagues are reinterpreted, taking into account the facilitation which is experimentally demonstrated in the first of their series of articles. It is shown that the original data equally well or better support a quite different set of conclusions from those drawn by Libet. The new conclusions are that it takes only 80 ms for stimuli to come to consciousness and that “subjective back-referral of sensations in time” to the time of the stimulus (...) does not occur.

The duration of “now” is shown to be important not only for an understanding of how conscious beings sense duration, but also for the validity of the phenomenological enterprise as Husserl conceived it. If “now” is too short, experiences can not be described before they become memories, which can be considered to be transcendent rather than immanent phenomena and therefore inadmissible as phenomenological data. Evidence concerning (a) the objective duration of sensations in various sensory modalities, (b) the time necessary for (...) sensations to enter consciousness and (c) the variability in the subjective sense of time's passing under different conditions is used to conclude that the duration of “now” can actually vary under normal conditions from about 10 ms to several seconds and in extreme cases up to several hours. Thus the immanent moment can be long enough to encompass a report of the contents of consciousness, making phenomenology a viable project. A further speculation from the evidence described is that consciousness takes discrete samples of the external world, at a rate inversely proportional to the duration of the “now” moment. (shrink)

Empirical work is reviewed which correlates the presence or absence of various parts of the auditory evoked potential with the disappearance and reemergence of auditory sensation during induction of and recovery from anesthesia. As a result, the hypothesis is generated that the electrophysiological correlate of auditory sensation is whatever neural activity generates the middle latency waves of the auditory evoked potential. This activity occurs from 20 to 80 ms poststimulus in the primary and secondary areas of the auditory cortex. Evidence (...) is presented suggesting that earlier or later waves in the auditory evoked potential do not covary with auditory sensation (as opposed to auditory perception) and it is therefore suggested that they are possibly not the electrophysiological correlates of sensation.

Philosophers have long struggled to understand our perceptual experience of temporal properties such as succession, persistence and change. Indeed, strikingly, a number have felt compelled to deny that we enjoy such experience. Philosophical puzzlement arises as a consequence of assuming that, if one experiences succession or temporal structure at all, then one experiences it at a moment. The two leading types of theory of temporal awareness—specious present theories and memory theories—are best understood as attempts to explain how temporal awareness is (...) possible within the constraints of this principle. I argue that the principle is false. Neither theory of temporal awareness can be made workable unless it is rejected. Our experience of temporal phenomena cannot be understood if we attempt to break experience down into instantaneous slices. In order to understand the perception of temporal properties we must look beyond the instant. (shrink)

The presentist view of time is psychologically appealing. I argue that, ironically, contingent facts about the temporal properties of consciousness are very difficult to square with presentism unless some form of mind/body dualism is embraced.

This is the second volume of philosophical essays by one of the most innovative and influential philosophers now writing in English. Containing thirteen papers in all, the book includes both new essays and previously published papers, some of them with extensive new postscripts reflecting Lewis's current thinking. The papers in Volume II focus on causation and several other closely related topics, including counterfactual and indicative conditionals, the direction of time, subjective and objective probability, causation, explanation, perception, free will, and rational (...) decision. Throughout, Lewis analyzes global features of the world in such a way as to show that they might turn out to supervene on the spatiotemporal arrangement of local qualities. (shrink)

Most modern analytic philosophers have ignored works of Indian philosophy such as Vasubandhu's 'Treasury of Metaphysics'. This neglect is unjustified. The account of the nature of the physical world given in the 'Treasury' is a one-category ontology of dharmas, which are simple, momentary tropes. They include basic physical tropes, the most fundamental level of the physical world, as well as higher-level tropes, including sensible properties such as colours, which are known as derived form. I argue that the relationship between the (...) basic physical tropes and derived form is one of supervenience. Vasubandhu's theory is a powerful and flexible one, which can be adapted so as to be consistent with modern science. (shrink)

This introductory chapter attempts to clarify the philosophical, empirical, and theoretical bases on which a cognitive neuroscience approach to consciousness can be founded. We isolate three major empirical observations that any theory of consciousness should incorporate, namely (1) a considerable amount of processing is possible without consciousness, (2) attention is a prerequisite of consciousness, and (3) consciousness is required for some specific cognitive tasks, including those that require durable information maintenance, novel combinations of operations, or the spontaneous generation of intentional (...) behavior. We then propose a theoretical framework that synthesizes those facts: the hypothesis of a global neuronal workspace. This framework postulates that, at any given time, many modular cerebral networks are active in parallel and process information in an unconscious manner. An information becomes conscious, however, if the neural population that represents it is mobilized by top-down attentional amplification into a brain-scale state of coherent activity that involves many neurons distributed throughout the brain. The long-distance connectivity of these `workspace neurons' can, when they are active for a minimal duration, make the information available to a variety of processes including perceptual categorization, long-term memorization, evaluation, and intentional action. We postulate that this global availability of information through the workspace is what we subjectively experience as a conscious state. A complete theory of consciousness should explain why some cognitive and cerebral representations can be permanently or temporarily inaccessible to consciousness, what is the range of possible conscious contents, how they map onto specific cerebral circuits, and whether a generic neuronal mechanism underlies all of them. We confront the workspace model with those issues and identify novel experimental predictions. Neurophysiological, anatomical, and brain-imaging data strongly argue for a major role of prefrontal cortex, anterior cingulate, and the areas that connect to them, in creating the postulated brain-scale workspace.

Dreyfus examines the central ideas of Dharmakīrti, one of the most important Indian Buddhist philosophers, and their reception among Tibetan thinkers. During the golden age of ancient Indian civilization, Dharmakīrti articulated and defended Buddhist philosophical principles. He did so more systematically than anyone before his time (the seventh century CE) and was followed by a rich tradition of profound thinkers in India and Tibet. This work presents a detailed picture of this Buddhist tradition and its relevance to the history of (...) human ideas. Its perspective is mostly philosophical, but it also uses historical considerations as they relate to the evolution of ideas. (shrink)

Early Buddhist Metaphysics provides a philosophical account of the major doctrinal shift in the history of early Theravada tradition in India: the transition from the earliest stratum of Buddhist thought to the systematic and allegedly scholastic philosophy of the Pali Abhidhamma movement. Entwining comparative philosophy and Buddhology, the author probes the Abhidhamma's metaphysical transition in terms of the Aristotelian tradition and vis-à-vis modern philosophy, exploits Western philosophical literature from Plato to contemporary texts in the fields of philosophy of mind and (...) cultural criticism.

Original in content and approach, Philosophy in Classical India focuses on the rational principles of Indian philosophical theory, rather than the mysticism usually associated with it. Ganeri explores the philosophical projects of a number of major Indian philosophers and looks into the methods of rational inquiry deployed within these projects. In so doing, he illuminates a network of mutual reference and criticism, influence and response, in which reason is simultaneously used constructively and to call itself into question.

_Stream of Consciousness_ is about the phenomenology of conscious experience. Barry Dainton shows us that stream of consciousness is not a mosaic of discrete fragments of experience, but rather an interconnected flowing whole. Through a deep probing into the nature of awareness, introspection, phenomenal space and time consciousness, Dainton offers a truly original understanding of the nature of consciousness.
