The phenomenon of multiple personality--Like the "split-Brain" phenomenon--Involves a disintegration of the normally unified self to the point where one must question whether there is one, Or more than one, Person associated with the body even at a single moment in time. Besides the traditional problem of determining identity over time, There is now a new problem of personal identity--Determining identity at a single moment in time. We need the conceptual apparatus to talk about this new problem and a test, (...) Like the one I propose, For determining the number of persons associated with a body at a single moment in time.

Since its publication in 1959, Individuals has become a modern philosophical classic. Bold in scope and ambition, it continues to influence debates in metaphysics, philosophy of logic and language, and epistemology. Peter Strawson's most famous work, it sets out to describe nothing less than the basic subject matter of our thought. It contains Strawson's now famous argument for descriptive metaphysics and his repudiation of revisionary metaphysics, in which reality is something beyond the world of appearances. Throughout, Individuals advances some highly (...) influential and controversial ideas, such as 'non-solipsistic consciousness' and the concept of a person a 'primitive concept'. (shrink)

The classic, influential essay in 'descriptive metaphysics' by the distinguished English philosopher.

Commissurotomy surgery has lately attracted considerable philosophical attention. It has seemed to some that the surgical scalpel that bisects the brain bisects consciousness and the mind as well; and that the ordinary concept of a person is thereby most seriously threatened. I shall assess the extent of the threat, arguing that it is overestimated. The argument begins with section III; section II, which describes the operation and its effects, should be omitted by those already familiar with these facts.

Physical and chemical processes may act upon the mind; and when we are writing a difficult letter, our mind acts upon our body and, through a chain of physical...

Reviews evidence which suggests that there may be little or no direct introspective access to higher order cognitive processes. Ss are sometimes unaware of the existence of a stimulus that importantly influenced a response, unaware of the existence of the response, and unaware that the stimulus has affected the response. It is proposed that when people attempt to report on their cognitive processes, that is, on the processes mediating the effects of a stimulus on a response, they do not do (...) so on the basis of any true introspection. Instead, their reports are based on a priori, implicit causal theories, or judgments about the extent to which a particular stimulus is a plausible cause of a given response. This suggests that though people may not be able to observe directly their cognitive processes, they will sometimes be able to report accurately about them. Accurate reports will occur when influential stimuli are salient and are plausible causes of the responses they produce, and will not occur when stimuli are not salient or are not plausible causes.

Many philosophers, both past and present, object to materialism not from any romantic anti-scientific bent, but from sheer inability to understand the thesis. It seems utterly inconceivable to some that qualia should exist in a world which is entirely material. This paper investigates the grain objection, a much neglected argument which purports to prove that sensations could not be brain events. Three versions are examined in great detail. The plausibility of the first version is shown to depend crucially on whether (...) one holds a direct or non-direct theory of perception. Only on the latter is this version plausible. An analysis of the second "semantic" version concludes that a materialist description and explanation of the world should not be expected to transparently convey all that would be of interest or importance to human beings. The final version explicitly makes use of Grover Maxwell's non-direct perceptual theory of structural realism. Although a confusion is charged to Maxwell between phenomenal and objective properties, the critical difficulty for the grain objection is its failure to characterize "structure" from a non-percipient point of view. As the grain objection is ultimately found wanting, the real difficulty for materialism crystallizes as its irreconciliability with the mere existence of sentience, which seems to force some sort of emergence upon us.

An examination of split-brain syndrome, and whether split-brain patients have two minds.

A seminal work on the unconscious and its mechanisms. Examines the interaction between voluntary (conscious) and involuntary (unconscious) human control mechanisms in terms of dissociation of divided consciousness. Delineates a neodissociation interpretation that recognizes historical roots without requiring commitment. Presents a wide range of data on possession states, fugues, multiple personalities, amnesia, dreams, hallucinations, automatic writing, and aggressions.

This edition's postscript includes further reflections on these themes and others, and relates them to recent writings of other philosophers and computer ...

CONSCIOUSNESS AND THE BRAIN SELF-REGULATION PARADOX The relationship of consciousness to biology has intrigued mankind thoroughout recorded history. However, little progress has been made not only in understanding these issues but also in raising fundamental questions central to the problem. As Davidson and Davidson note in their introduction, William James suggested, almost a century ago in his Principles of Psychology, that the brain was the organ of mind and be havior. James went so far as to suggest that the remainder (...) of the Principles was but a "footnote" to this central thesis. This volume brings together diverse biobehavioral scientists who are addressing the various aspects of the mindlbrainlbodylbehavior issue. Although some of the authors have previously published together in other volumes, by and large the particular combination of authors and topics selected by the editors makes this volume unique and timely. Unlike the Consciousness and Self-Regulation series (Schwartz & Shapiro, 1976, 1978), also published by Plenum, this volume is devoted entirely to a psychobiological approach to consciousness. Although readers will differ in their interest in specific chapters, the well-rounded investigator who is concerned with the psychobiology of consciousness will want to become intimately acquainted with all the views presented in this volume. As noted by the individual contributors, the topic of this volume stimulates fundamental questions which, on the surface, may appear trivial, yet, on further reflection, turn out to have deep significance.
