Given Bergson’s commitment to a dynamic conception of time and an open future it seems likely that he would not have welcomed developments in physics which suggest that we live in an eternal four-dimensional block-universe. The route from Einstein’s special theory of relativity to the eternalist conception of time has been thoroughly explored — and Bergson himself explored ways of reconciling his own doctrines with Einstein’s theory. But there is more than one route from physics to the block-universe. The route I am concerned with here may be less familiar than Einstein’s, but is potentially of considerable significance since some contemporary physicists believe it may well be the physics of the future. Denis Villeneuve’s recent movie Arrival — together with the science fiction story by Ted Chiang it is based upon — provide useful points of entry into the relevant science.

The notion of “phenomenal field” often occurs when philosophers attempt to characterize the unity of consciousness. The phenomenal unity relationship is distinct from the coinstantiation relation. There are grounds for supposing that experiences can be phenomenally unified in the absence of any higher‐order conscious state, and in the absence of any spatial relations of a phenomenal kind. There is a way in which phenomenal unity can be construed as a primitive feature of experience. Rather than starting off from the perspective of particular experiences and looking for what binds them into more complex states, we can start with the more complex states, and regard simpler token experiences as unified by virtue of being parts of such states. The phenomenal unity relationship can as easily be viewed as a relationship between experiential parts, as it can experiential wholes.

Barry Dainton’s controversial and highly original _Stream of Consciousness_ aroused considerable interest when it was first published. This new paperback edition includes a postscript in which Dainton responds to some of his critics. Despite the recent upsurge of interest in consciousness, most of this has been focused on the relationship between consciousness and the brain. This has meant that significant and intriguing questions concerning the fundamental characteristics of consciousness itself have not received the attention they deserve. _Stream of Consciousness_ is devoted to these questions by presenting a systematic, phenomenological inquiry into the most general features of conscious life: the nature of awareness, introspection, phenomenal space and time-consciousness. Barry Dainton shows us that a stream of consciousness is not a mosiac of discrete fragments of experience, but rather an interconnected flowing whole. This compelling discussion about the structure of consciousness will interest anyone concerned with current debates on consciousness in philosophy, psychology and neuroscience.

The first edition (2001) of this title quickly established itself on courses on the philosophy of time and space. This fully revised and expanded new edition sees the addition of chapters on Zeno's paradoxes, speculative contemporary developments in physics, and dynamic time, making the second edition, once again, unrivalled in its breadth of coverage. Surveying both historical debates and the ideas of modern physics, Barry Dainton evaluates the central arguments in a clear and unintimidating way and is careful to keep the conceptual issues throughout comprehensible to students with little scientific or mathematical training. The book makes the philosophy of space and time accessible for anyone trying to come to grips with the complexities of this challenging subject. With over 100 original line illustrations and a full glossary of terms, the book has the requirements of students firmly in sight and will continue to serve as an essential textbook for philosophy of time and space courses.

The James‐Husserl thesis is potentially of great importance for the understanding of consciousness. While there may be a good deal of agreement on the need to posit a specious present in some form or other, there is profound disagreement over the correct way of conceiving of it. This chapter surveys some of the more important landmarks in this contentious territory. An account of what is the specious present was elaborated by Brentano in lectures in the 1860s. Brentano fully appreciated the importance to phenomenology – “descriptive psychology” – of understanding how people manage to perceive temporal succession. The Orthogonal and Extensional accounts of people's temporal experience are in two respects very similar. Both sides agree that change, succession, and persistence figure prominently and vividly in people's immediate experience, over short intervals of time; they also agree that this is possible in virtue of an abiding structural feature of people's consciousness.

Although many find it hard to believe that every physical thing—no matter how simple or small—involves some form of consciousness, panpsychists offer the reassurance that their claims are perfectly compatible with everything physics has to say about the physical world. This is because although physics has a lot to say about causal and structural properties it has nothing to say about the intrinsic natures of physical things, and if physics is silent in this regard it is perfectly possible that everything physical has an experiential intrinsic nature. Following in Thomas Nagel’s footsteps, panpsychists have also argued that by revealing that everything is composed of the same fundamental ingredients, physics provides grounds for holding that if any physical things (e.g. our neural processes) have an experiential intrinsic nature then all must. My main contention in this paper is that the relationship between physics and panpsychism is considerably more complex than panpsychists have tended to assume. Nagel’s reasoning may be sound in the context of simplistic atomic theories which posit just one kind of fundamental particle. However, it begins to look distinctly dubious in the context of the diverse range of primitive entities that are to be found in the Standard Model of particle physics. Galen Strawson has suggested that mass-energy interconvertibility should be regarded as evidence that everything physical has the same intrinsic nature. I suggest Strawson’s claim relies on a dubious construal of the nature of energy. Special relativity is another of the cornerstones of contemporary physics, and it too makes life difficult for panpsychists, a fact which emerges when we consider what it would like to be a ray of light. However in this case I suggest that there is an interesting—if radical—move open to the panpsychist: they can simply deny that light exists. To conclude I briefly consider whether what QCD has revealed about the nature of mass poses a problem for panpsychism.

Bringing together literary scholars, computer scientists, ethicists, philosophers of mind, and scholars from affiliated disciplines, this collection of essays offers important and timely insights into the pasts, presents, and, above all, possible futures of Artificial Intelligence. This book covers topics such as ethics and morality, identity and selfhood, and broader issues about AI, addressing questions about the individual, social, and existential impacts of such technologies. Through the works of science fiction authors such as Isaac Asimov, Stanislaw Lem, Ann Leckie, Iain M. Banks, and Martha Wells, alongside key visual productions such as Ex Machina, Westworld, and Her, contributions illustrate how science fiction might inform potential futures as well as acting as a springboard to bring disciplinary knowledge to bear on significant developments of Artificial Intelligence. Addressing a broad, interdisciplinary audience, both expert and non-expert readers gain an in-depth understanding of the wide range of pressing issues to which Artificial Intelligence gives rise, and the ways in which science fiction narratives have been used to represent them. Using science fiction in this manner enables readers to see how even fictional worlds and imagined futures have very real impacts on how we understand these technologies. As such, readers are introduced to theoretical positions on Artificial Intelligence through fictional works as well as encouraged to reflect on the diverse aspects of Artificial Intelligence through its many philosophical, social, legal, scientific, and cultural ramifications.

The concept of force can seem comparatively unproblematic—forces are responsible for making things move. However, the history of both physics and metaphysics reveals considerable controversy concerning both the nature of forces, and their very existence. My survey takes in the Greek atomists, Aristotelian physics, the “mechanical” philosophy of the scientific revolution, the innovations of Descartes and Newton, Hume-inspired skepticism, the dynamism of Leibniz, Kant and Boscovich, the field theories of Faraday and Maxwell, and the impact of Einstein’s relativity theories and quantum mechanics. A recurring theme is the contrasting attitudes taken towards “action at a distance” causal influences by both philosophers and scientists.

Different conceptions of the nature of subjects of experience have very different implications for the sort of relationship which exists between subjects and their experiences. On my preferred view, since subjects consist of nothing but capacities for experience, the ‘having’ of an experience amounts to a subject’s producing it. This relationship may look to be problematic, but I argue that here at least appearances are deceptive. I then move on to consider some of the ways in which experiences can seem to have subjects or owners, and argue that those who take a ‘sense of self’ to be an essential feature of all forms of consciousness may well be mistaken.

Those who believe suitably programmed computers could enjoy conscious experience of the sort we enjoy must accept the possibility that their own experience is being generated as part of a computerized simulation. It would be a mistake to dismiss this is just one more radical sceptical possibility: for as Bostrom has recently noted, if advances in computer technology were to continue at close to present rates, there would be a strong probability that we are each living in a computer simulation. The first part of this paper is devoted to broadening the scope of the argument: even if computers cannot sustain consciousness (as many dualists and materialists believe), there may still be a strong likelihood that we are living simulated lives. The implications of this result are the focus of the second part of the paper. The topics discussed include: the Doomsday argument, scepticism, the different modes of virtual life, transcendental idealism, the Problem of Evil, and simulation ethics.

Available from UMI in association with The British Library. Requires signed TDF. ;We are mental beings whose identity is absolute, intrinsic and real. This conception of the self, which, it is argued, corresponds to our deeper beliefs about, and attitudes towards, ourselves and others, is a consequence of taking the experienced unity and continuity of consciousness as the key to self-identity. Some of the difficulties often taken as fatal to this "subjectivist" view of the self, considerations concerning private languages and the individuation of conscious beings from within pure consciousness, are disposed of in Chapter 2. The next two chapters focus on the stream of consciousness. It is shown that the unity and copersonality of intra-streamal experiences both at and over time is constituted by and experience of unity. Building on this result, in Chapter 5 an account of the self as a mental entity whose identity consists in the persistence of potential streamal experience is developed. The notion of the Pure Ego is then examined; the reasons for positing such an entity are found wanting; but the neoHumean account of the self which has by this point emerged is compatible with the intuition that the self is a simple and basic entity, distinct from its actual mental states. In Chapter 7 the alleged possibility of selves undergoing fission and fusion is investigated. This is found to be a genuine possibility, but the claim that we should conclude from this that self-identity is not a relation which deeply matters is rejected, on the grounds that when a self divides, the products of fission are identical with one another. The apparent absurdity of this result is reduced by taking seriously the notion of topologically deviant subjective time dimensions; our identity matters, but our lives need not be linear.

According to proponents of ‘phenomenal holism’, the intrinsic characteristics of the parts of unified conscious states are dependent to some degree on the characteristics of the wholes to which they belong. Although the doctrine can easily seem obscure or implausible, there are eminent philosophers who have defended it, amongst them Timothy Sprigge. In Stream of Consciousness (2000) I found Sprigge’s case for phenomenal holism problematic on several counts; in this paper I re-assess some of these criticisms. Recent experimental work suggests cross-modal perceptual interference may be far more prevalent than expected. I argue that although these results do lend support to phenomenal holism in one of its guises, they do not support the strong form of holism espoused by Sprigge. I then move on to consider the relevance and impact of certain gestalt-related considerations, and argue that these considerations at best establish that the stronger form of holism applies to some parts of some experiential states, but not to all parts of all states, as Sprigge claims. I then consider a more promising way forward for anyone who wishes to defend an across-the-board holism of the strong variety, arguing that what is required is a form of phenomenal interdependence that is rooted solely in phenomenal unity. I conclude by outlining a case for thinking that an interdependence of this sort is a quite general feature of unified conscious states.

Analytic philosophy in the 20 th century was largely hostile territory to the self as traditionally conceived, and this tradition has been continued in two recent works: Mark Johnston’s Surviving Death, and Galen Strawson’s Selves. I have argued previously that it is perfectly possible to combine a naturalistic worldview with a conception of the self as a subject of experience, a thing whose only essential attribute is a capacity for unifi ed and continuous experience. I argue here that this conception of the self is unthreatened by the otherwise valuable considerations advanced by Johnston and Strawson. Both are inclined to identify selves-at-times with momentary episodes of experience (or centres or ‘arenas’ of consciousness). Both go on to argue, albeit in diff erent ways, that individual selves cannot extend beyond the confi nes of these brief episodes. However, in so doing they give insuffi cient weight to an important phenomenological datum: the continuity of our ordinary experience. When the latter is recognized, and appropriately understood, it provides us with a secure basis upon which a more recognizable conception of the self can be constructed.
