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)

In 1931 the mathematical logician Kurt Godel published a revolutionary paper that challenged certain basic assumptions underpinning mathematics and logic. A colleague of Albert Einstein, his theorem proved that mathematics was partly based on propositions not provable within the mathematical system and had radical implications that have echoed throughout many fields. A gripping combination of science and accessibility, _Godel’s Proof_ by Nagel and Newman is for both mathematicians and the idly curious, offering those with a taste for logic and philosophy (...) the chance to satisfy their intellectual curiosity.

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work is his attempt to reverse the proposition of philosophy of the modern period that posits the self as thinker withdrawn from action and essentially isolated from the world about which it reflects.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.

A Nobel prize winner, a great man and a great scientist, Erwin Schrödinger has made his mark in physics, but his eye scans a far wider horizon: here are two stimulating and discursive essays which summarize his philosophical views on the nature of the world. Schrödinger's world view, derived from the Indian writings of the Vedanta, is that there is only a single consciousness of which we are all different aspects. He admits that this view is mystical and metaphysical and (...) incapable of logical deduction. But he also insists that this is true of the belief in an external world capable of influencing the mind and of being influenced by it. Schrödinger's world view leads naturally to a philosophy of reverence for life. (shrink)

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)

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.

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)

This paper is about the neglected question of what sort of things we are metaphysically speaking. It is different from the mind-body problem and from familiar questions of personal identity. After explaining what the question means and how it differs from others, the paper tries to show how difficult it is to give a satisfying answer.

Most philosophers writing about personal identity in recent years claim that what it takes for us to persist through time is a matter of psychology. In this groundbreaking new book, Eric Olson argues that such approaches face daunting problems, and he defends in their place a radically non-psychological account of personal identity. He defines human beings as biological organisms, and claims that no psychological relation is either sufficient or necessary for an organism to persist. Olson rejects several famous thought-experiments dealing (...) with personal identity. He argues, instead, that one could survive the destruction of all of one's psychological contents and capabilities as long as the human organism remains alive--as long as its vital functions, such as breathing, circulation, and metabolism, continue.

Personal Identity is a comprehensive introduction to the nature of the self and its relation to the body. Harold Noonan places the problem of personal identity in the context of more general puzzles about identity, discussing the major historical theories and more recent debates. The second edition of Personal Identity contains a new chapter on 'animalism' and a new section on vagueness.

What is the self? And how does it relate to the body? In the second edition of Personal Identity, Harold Noonan presents the major historical theories of personal identity, particularly those of Locke, Leibniz, Butler, Reid and Hume. Noonan goes on to give a careful analysis of what the problem of personal identity is, and its place in the context of more general puzzles about identity. He then moves on to consider the main issues and arguments which are the subject (...) of current debate, including the work of Bernard Williams and Derek Parfit, and makes new and challenging interpretations of them. This new edition contains additional material assessing the biological approach which has become increasingly popular in recent years, and extends the treatment of indeterminate identity to take account of the epistemic view of vagueness. This book covers the problem of personal identity from its origin in Locke's work to the most recent debates in the philosophical literature, and will be invaluablereading for any student of the topic.

Self-knowledge is based on several different forms of information, so distinct that each one essentially establishes a different 'self. The ecological self is the self as directly perceived with respect to the immediate physical environment; the interpersonal self, also directly perceived, is established by species-specific signals of emotional rapport and communication; the extended self is based on memory and anticipation; the private self appears when we discover that our conscious experiences are exclusively our own; the conceptual self or 'self-concept' draws (...) its meaning from a network of socially-based assumptions and theories about human nature in general and ourselves in particular. Although these selves are rarely experienced as distinct (because they are held together by specific forms of stimulus information), they differ in their developmental histories, in the accuracy with which we can know them, in the pathologies to which they are subject, and generally in what they contribute to human experience.
