Conscious experience is one of the most difficult and thorny problems in psychological science. Its study has been neglected for many years, either because it was thought to be too difficult, or because the relevant evidence was thought to be poor. Bernard Baars suggests a way to specify empirical constraints on a theory of consciousness by contrasting well-established conscious phenomena - such as stimulus representations known to be attended, perceptual, and informative - with closely comparable unconscious ones - such as (...) stimulus representations known to be preperceptual, unattended, or habituated. Adducing data to show that consciousness is associated with a kind of global workplace in the nervous system, and that several brain structures are known to behave in accordance with his theory, Baars helps to clarify many difficult problems.

In The Emergent Self, William Hasker joins one of the most heated debates in contemporary analytic philosophy, that over the nature of mind.

Thomas Reid was a philosopher who founded the Scottish school of 'common sense'. Much of Reid's work is a critique of his contemporary, David Hume, whose empiricism he rejects. In this work, written after Reid's appointment to a professorship at the university of Glasgow, and published in 1785, he turns his attention to ideas about perception, memory, conception, abstraction, judgement, reasoning and taste. He examines the work of his predecessors and contemporaries, arguing that 'when we find philosophers maintaining that there (...) is no heat in the fire, nor colour in the rainbow … we may be apt to think the whole to be only a dream of fanciful men, who have entangled themselves in cobwebs spun out of their own brain'. Written by one of the Scottish Enlightenment's most important thinkers, this work brings to life the intellectual debates of the time. (shrink)

Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

This paper examines the issue of what the self is by reviewing neuropsychological research,which converges on the idea that the self may be more complex and differentiated than previous treatments of the topic have suggested. Although some aspects of self-knowledge such as episodic recollection may be compromised in individuals, other aspects—for instance, semantic trait summaries—appear largely intact. Taken together, these findings support the idea that the self is not a single, unified entity. Rather, it is a set of interrelated, functionally (...) independent systems. Implications for understanding the self in various areas of psychological research—e.g., neuroimaging, autism, amnesia, Alzheimer’s disease, and mirror self-recognition—are discussed in brief.

The incredible achievements of modern scientific theories lead most of us to embrace scientific realism: the view that our best theories offer us at least roughly accurate descriptions of otherwise inaccessible parts of the world like genes, atoms, and the big bang. In Exceeding Our Grasp, Stanford argues that careful attention to the history of scientific investigation invites a challenge to this view that is not well represented in contemporary debates about the nature of the scientific enterprise. The historical record (...) of scientific inquiry, Stanford suggests, is characterized by what he calls the problem of unconceived alternatives. Past scientists have routinely failed even to conceive of alternatives to their own theories and lines of theoretical investigation, alternatives that were both well-confirmed by the evidence available at the time and sufficiently serious as to be ultimately accepted by later scientific communities. Stanford supports this claim with a detailed investigation of the mid-to-late 19th century theories of inheritance and generation proposed in turn by Charles Darwin, Francis Galton, and August Weismann. He goes on to argue that this historical pattern strongly suggests that there are equally well-confirmed and scientifically serious alternatives to our own best theories that remain currently unconceived. Moreover, this challenge is more serious than those rooted in either the so-called pessimistic induction or the underdetermination of theories by evidence, in part because existing realist responses to these latter challenges offer no relief from the problem of unconceived alternatives itself. Stanford concludes by investigating what positive account of the spectacularly successful edifice of modern theoretical science remains open to us if we accept that our best scientific theories are powerful conceptual tools for accomplishing our practical goals, but abandon the view that the descriptions of the world around us that they offer are therefore even probably or approximately true.

John Barrow is increasingly recognized as one of our most elegant and accomplished science writers, a brilliant commentator on cosmology, mathematics, and modern physics. Barrow now tackles the heady topic of impossibility, in perhaps his strongest book yet. Writing with grace and insight, Barrow argues convincingly that there are limits to human discovery, that there are things that are ultimately unknowable, undoable, or unreachable. He first examines the limits on scientific inquiry imposed by the deficiencies of the human mind: our (...) brain evolved to meet the demands of our immediate environment, Barrow notes, and much that lies outside this small circle may also lie outside our understanding. Barrow investigates practical impossibilities, such as those imposed by complexity, uncomputability, or the finiteness of time, space, and resources. Is the universe finite or infinite? Can information be transmitted faster than the speed of light? The book also examines the deeper theoretical restrictions on our ability to know, including Godel's theorem--which proved that there were things that could not be proved--and Arrow's Impossibility theorem about democratic voting systems. Finally, having explored the limits imposed on us from without, Barrow considers whether there are limits we should impose upon ourselves. For instance, if the secrets of the atom are to be found only by recreating extreme environments at great financial cost, just how much should we devote to that quest? Weaving together this intriguing tapestry, he illuminates some of the most profound questions of science, from the possibility of time travel to the very structure of the universe. (shrink)

Reprint of the original, first published in 1919.

The seminal work by one of the most important thinkers of the twentieth century, Physics and Philosophy is Werner Heisenberg's concise and accessible narrative of the revolution in modern physics, in which he played a towering role. The outgrowth of a celebrated lecture series, this book remains as relevant, provocative, and fascinating as when it was first published in 1958. A brilliant scientist whose ideas altered our perception of the universe, Heisenberg is considered the father of quantum physics; he is (...) most famous for the Uncertainty Principle, which states that quantum particles do not occupy a fixed, measurable position. His contributions remain a cornerstone of contemporary physics theory and application. Book jacket. (shrink)

A scientific community cannot practice its trade without some set of received beliefs. These beliefs form the foundation of the "educational initiation that prepares and licenses the student for professional practice". The nature of the "rigorous and rigid" preparation helps ensure that the received beliefs are firmly fixed in the student's mind. Scientists take great pains to defend the assumption that scientists know what the world is like...To this end, "normal science" will often suppress novelties which undermine its foundations. Research (...) is therefore not about discovering the unknown, but rather "a strenuous and devoted attempt to force nature into the conceptual boxes supplied by professional education". (shrink)

Thomas S. Kuhn's classic book is now available with a new index.

At the heart of Macmurray's work is his attempt to reverse the proposition of philosophy of the modern period that posits the self as thinker withdrawn from action and essentially isolated from the world about which it reflects. Macmurray labored to recast the role of philosophy in the service of a more fulfilling and basic personal communion with others, with the world, and ultimately with God. Indeed, it can be said that Macmurray's philosophy is really a philosophy of community—a philosophy (...) that relates to many contemporary philosophical and religious concerns, as well as having a bearing on current historical/sociological, political, and feminist critiques of contemporary American society.

Suitable for students and scholars, this title challenges the assumption that skepticism, rather than established belief, lies at the heart of scientific discovery.

Can we understand what makes someone the same person without understanding what it is to be a person? Prereflectively we might not think so, but philosophers often accord these questions separate treatments, with personal-identity theorists claiming the first question and free-will theorists the second. Yet much of what is of interest to a person—the possibility of survival over time, compensation for past hardships, concern for future projects, or moral responsibility—is not obviously intelligible from the perspective of either question alone. Marya (...) Schechtman encourages us to adopt a more unified perspective. (shrink)

In these essays Stephen White examines the forms of psychological integration that give rise to self-knowable and self-conscious individuals who are responsible, concerned for the future, and capable of moral commitment. The essays cover a wide range of basic issues in philosophy of mind, metaphysics, moral psychology, and political philosophy, providing a coherent, sophisticated, and forcefully argued view of the nature of the self. Beginning with mental content and ending with Rawls and utilitarianism, each essay argues a distinctive line. Together (...) they are a unified and powerful philosophical position of considerable scope, one that provides a unique vision of the mind, consciousness, personhood, and morality. White argues that the unity of the self revealed in personal identity and moral responsibility is best understood in normative terms. Basic to such features of the self are the patterns of self-concern in which they are characteristically displayed and the internal justification that supports such concern. The treatment of intentionality and consciousness that grounds this account emphasizes privileged selfknowledge and practical rationality and their corresponding contributions to the unity of the self. A final source of unity emerges from the analysis of our fundamental commitments, an analysis that ensures a central place in moral theory for the notion of the self. (shrink)

I exist, but I am not a thing among things; X exists if and only if there is something such that it=X. This is consistent, and it is a view that can be supported. Calvino’s novel The Non‐Existent Knight can be read so as to illustrate this view. But what is my relation to the things there are if I am not identical with any of them – things such as my arms, my garden, the city I live in? I (...) name this the Gurduloo problem, after the Knight’s page. This relation must be one that admits of degrees; I suggest that we say that I manifest myself through the things thus associated with me. Several pseudo‐problems, pertaining to volitional action, supervenience, observability, and the emergence of consciousness, dissolve upon inspection. (shrink)

The topic of personal identity has prompted some of the liveliest and most interesting debates in recent philosophy. In a fascinating new contribution to the discussion, Peter Unger presents a psychologically aimed, but physically based, account of our identity over time. While supporting the account, he explains why many influential contemporary philosophers have underrated the importance of physical continuity to our survival, casting a new light on the work of Lewis, Nagel, Nozick, Parfit, Perry, Shoemaker, and others. Deriving from his (...) discussion of our identity itself, Unger produces a novel but commonsensical theory of the relations between identity and some of our deepest concerns. In a conservative but flexible spirit, he explores the implications of his theory for questions of value and of the good life. (shrink)

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.

According to B-theorists, B-relations (‘earlier than’ and ‘later than’, see, e.g. Oaklander 2004: 24–25) constitute the reality of time. The B-relations are what distinguish our world from a timeless one. Yet our only awareness of the reality of time comes via our phenomenology of temporal passage. Why is this noteworthy? Our temporal phenomenology is mind-dependent and reflects no feature of reality. Epistemic access to the reality of time is, in fact, simply epistemic access to our own inner phenomenology. It doesn’t (...) reflect the way reality is. Hence, we have no understanding of what ‘B-time’ is. (shrink)

This book argues that in fact it is Locke 's critics who are wrong, and that the famous objections to his theory are invalid.

Over the centuries, the idea of the self has both fascinated and confounded philosophers. From the ancient Greeks, who problematized issues of identity and self-awareness, to Locke and Hume, who popularized minimalist views of the self, to the efforts of postmodernists in our time to decenter the human subject altogether, the idea that there is something called a self has always been in steady decline. But for Richard Sorabji, one of our most celebrated living intellectuals, this negation of the self (...) is dispiriting. In Self , he sets out to recover the rich variety of positive accounts of the self from Antiquity right up to the present, while offering his own inspiring view of what precisely the self might be. Drawing on Eastern religion, classical antiquity, and Western philosophy, Sorabji proceeds to tackle a number of thematic debates that have preoccupied philosophers over the ages, including the concept of the self, its sameness and mutability, the idea of the resurrection of the body and spirit, and the fear of death. According to Sorabji, the self is not an undetectable soul or ego, but an embodied individual whose existence is plain to see. It is also neither a linguistic creation nor a psychological fiction, but something that owns both a consciousness and a body. Ultimately, Sorabji argues, the demise of a positive idea of the self stems from much older and more pervasive problems of identity than we realize. Through an astute reading of this tradition, he helps us come to terms with our uneasiness about the subject in an account that will be at the forefront of philosophical debates for years to come.

Richard Sorabji presents a brilliant exploration of the history of our understanding of the self, which has remained elusive and mysterious throughout the spectacular development of human knowledge of the outside world. He ranges from ancient to contemporary thought, Western and Eastern, to reveal and assess the insights of a remarkable variety of thinkers. On this basis he rejects the common idea that the self is an illusion, and develops his own original conception of the self as essential to our (...) ownership of our experience and our apprehension of the world.

What does it mean to say that this person at this time is 'the same' as that person at an earlier time? If the brain is damaged or the memory lost, how far does a person's identity continue? In this book two eminent philosophers develop very different approaches to the problem.

Marya Schechtman takes issue with analytic philosophy's emphasis on the first sort of question to the exclusion of the second.

Phenomenological psychiatry has suffered from a failure to translate its insights into terms specific enough to be applied to psychiatric diagnosis or to be used in contemporary research programs. This difficulty can be understood in light of the well-known tradeoff between reliability and validity. We argue, however, that with sufficient ingenuity, phenomenological concepts can be adapted and applied in a research context. Elsewhere, we have described a phenomenologically oriented conception of schizophrenia as a self- or ipseity-disorder with two main facets: (...) decline in the sense of existing as a subject of awareness (diminished self-affection) and heightened awareness of aspects of experience that would normally remain tacit or presupposed (hyperreflexivity). This approach is consistent with Minkowski, Blankenburg, and Kimura and offers one possible synthesis of their views. Here we describe two areas of empirical research that are congruent with, or actually inspired by, a phenomenological approach emphasizing such disorders of consciousness and self-experience: (1) Phenomenologically oriented, interview studies show that, whereas negative-symptom patients generally deny any diminishment of affect and thinking, they do describe qualitative alterations of experience suggestive of hyperreflexivity and diminished self-affection. (2) Another line of research suggests that the early detection of schizophrenic symptoms may be enhanced by adopting a phenomenological approach. (shrink)

No mental phenomenon is more central than consciousness to an adequate understanding of the mind. Nor does any mental phenomenon seem more stubbornly to resist theoretical treatment. Consciousness is so basic to the way we think about the mind that it can be tempting to suppose that no mental states exist that are not conscious states. Indeed, it may even seem mysterious what sort of thing a mental state might be if it is not a conscious state. On this way (...) of looking at things, if any mental states do lack consciousness, they are exceptional cases that call for special explanation or qualification. Perhaps dispositional or cognitive states exist that are not conscious, but nonetheless count as mental states. (shrink)

Is it conceptually possible for one person to ‘remember’ the experiences of another person? Many philosophical discussions of personal identity suppose that this is possible. For example, some philosophers believe that our personal identity through time consists in the continuation of our mental lives, including the holding of memories over time. However, since a person’s memories are necessarily memories of her own experiences, a definition of personal identity in terms of memory risks circularity. To avoid this, we must invoke the (...) concept of ‘quasi-memory’. From my quasi-memory of doing x, I cannot infer that I did x; but I can infer that somebody did x. It is then a further question as to whether the person who did x is me, the answer to which will depend upon what we believe personal identity to consist in. Quasi-memory, then, allows us to separate the concept of memory from the concept of personal identity. (shrink)

There are two fundamental aspects of the notion of a self: it is the owner of one's experiences, that to which one's experiences are properly attributed, and it perceives itself. is a condition on the self's being capable of attributing experiences to itself or being introspectively aware of its experiences, which constitutes a third, higher-order aspect of the self. I claim that it is a common sense assumption, enshrined in the use of 'I', that one's body satisfies the first two (...) aspects. I then argue that these two aspects are not really satisfied by one's body, which is essentially a human organism. Nor are they satisfied by anything of any other kind. So we are not identical to things of any kind, since one can be identical only to that which is one's self or is the referent of one's uses of, 'I'. (shrink)
