This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

EMPIRICIST THEORIES OF PERSONAL IDENTITY STATE THAT THE IDENTITY OF A PERSON OVER TIME IS A MATTER OF BODILY CONTINUITY AND/OR SIMILARITY OF MEMORY AND CHARACTER. IN CONTRAST, THIS PAPER ARGUES THAT WHILE BODILY CONTINUITY AND SIMILARITY OF MEMORY AND CHARACTER ARE EVIDENCE OF PERSONAL IDENTITY, THEY DO NOT CONSTITUTE IT. IT IS SOMETHING UNDEFINABLE. THE DIFFICULTY OF KNOWING WHAT TO SAY IN PUZZLE CASES DOES NOT SHOW THAT PERSONAL IDENTITY EXISTS IN DIFFERENT DEGREES OR THAT WE HAVE TO MAKE (...) ARBITRARY JUDGMENTS ABOUT IT. IT SHOWS ONLY THAT SOMETIMES WE CANNOT KNOW WHO IS WHO. (shrink)

_Naming and Necessity_ has had a great and increasing influence. It redirected philosophical attention to neglected questions of natural and metaphysical necessity and to the connections between these and theories of naming, and of identity. This seminal work, to which today's thriving essentialist metaphysics largely owes its impetus, is here reissued in a newly corrected form with a new preface by the author. If there is such a thing as essential reading in metaphysics, or in philosophy of language, this is (...) it. (shrink)

The late John L. Mackie, formerly of University College, Oxford.

Zombies are bodies without minds: creatures that are physically identical to actual human beings, but which have no conscious experience. Much of the consciousness literature focuses on considering how threatening philosophical reflection on such creatures is to physicalism. There is not much attention given to the converse possibility, the possibility of minds without bodies, that is, creatures who are conscious but whose nature is exhausted by their being conscious. We can call such a ‘purely conscious’ creature a ghost.

This article offers a novel, conservative account of material constitution, one that incorporates sortal essentialism and features a theory of dominant sortals. It avoids coinciding objects, temporal parts, relativizations of identity, mereological essentialism, anti-essentialism, denials of the reality of the objects of our ordinary ontology, and other departures from the metaphysic implicit in ordinary ways of thinking. Defenses of the account against important objections are found in Burke 1997, 2003, and 2004, as well as in the often neglected six paragraphs (...) that conclude section V of this article. (shrink)

A transcript of three lectures, given at Princeton University in 1970, which deals with (inter alia) debates concerning proper names in the philosophy of language.

The idea that we may continue to exist in a bodiless condition after our death has long played an important role in beliefs about immortality, ultimate rewards and punishments, the transmigration of souls, and the like. There has also been long and heated disagreement about whether the idea of disembodied existence even makes sense, let alone whether anybody can or does survive dissolution of his material form. It may seem doubtful that anything new could be added to the debate at (...) this late date, but I hope to show that this is not so. I will explore the problem of disembodiment from a somewhat different direction than has been tried before, one that leads to what seem to me more interesting and more definite conclusions about its unintelligibility. Furthermore, the approach I will be taking puts both the traditional mind-body problem and the competing claims of dualism and physicalism in a fresh light that can help us to understand better the nature of our embodied existence.

Human beings have the unique ability to view the world in a detached way: We can think about the world in terms that transcend our own experience or interest, and consider the world from a vantage point that is, in Nagel's words, "nowhere in particular". At the same time, each of us is a particular person in a particular place, each with his own "personal" view of the world, a view that we can recognize as just one aspect of the (...) whole. How do we reconcile these two standpoints--intellectually, morally, and practically? To what extent are they irreconcilable and to what extent can they be integrated? Thomas Nagel's ambitious and lively book tackles this fundamental issue, arguing that our divided nature is the root of a whole range of philosophical problems, touching, as it does, every aspect of human life. He deals with its manifestations in such fields of philosophy as: the mind-body problem, personal identity, knowledge and skepticism, thought and reality, free will, ethics, the relation between moral and other values, the meaning of life, and death. Excessive objectification has been a malady of recent analytic philosophy, claims Nagel, it has led to implausible forms of reductionism in the philosophy of mind and elsewhere. The solution is not to inhibit the objectifying impulse, but to insist that it learn to live alongside the internal perspectives that cannot be either discarded or objectified. Reconciliation between the two standpoints, in the end, is not always possible. (shrink)

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible , and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and arguments developed earlier to defend (...) a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

Despite the current resurgence of modest forms of mind–body dualism, traditional Cartesian immaterial-substance dualism has few, if any, defenders. This paper argues that no convincing case has been made against substance dualism, and that standard objections to it can be credibly answered.

Given the recent interest in the subjective or phenomenal dimension of consciousness it is no wonder that many authors have once more started to speak of the need for pheno- menological considerations. Often however the term ‘phenomenology’ is being used simply as a synonym for ‘folk psychology', and in our article we argue that it would be far more fruitful to turn to the argumentation to be found within the continental tradition inaugurated by Husserl. In order to exemplify this claim, (...) we criticize Rosenthal's higher-order thought theory as well as Strawson's recent contribution in this journal, and argue that a phenomenological analysis of the nature of self-awareness can provide us with a more sophisticated and accurate model for understanding both phenomenal consciousness and the notion of self.

Many materialist ontologies characterize the existence of everyday, middle-sized objects as reducible to collections or mereological sums of smaller, more fundamental particle constituents. Baker would have it otherwise and has set out a defence of her Constitution View of ontology that takes everyday objects to be irreducibly real and of a vast array of kinds.Motivating an interest in the metaphysics of everyday objects is not obviously straightforward when contemporary metaphysics is filled with attempts to answer seemingly more challenging questions about (...) the existence of disputed classes of objects, such as abstracta, or very specific, unusual phenomena such as holes, rather than the mundane case of these middle-sized concreta. Yet this is Baker's point: that many kinds of ordinary objects have been overlooked by philosophers to the point where we lack an adequate account of their significance in our practices and attitudes. Moreover, in a climate of metaphysics often governed by those of a strong eliminitivist inclination with a preference for Quinean desert landscapes, the advocating of an almost indulgent ontological pluralism is enough to make this book worth reading.Those familiar with Baker's work will not be surprised that this approach to ontology is grounded from her perspective of ‘Practical Realism’. This view – partly a legacy of Aristotle, partly of G. E. …. (shrink)

In the preface, Kim writes hopefully that his introduction to the philosophy of mind is “intended to be accessible to those without a formal background in philosophy”. The blurb at the end is more realistic: Philosophy of Mind is “a textbook for upper-level undergraduates and graduate students”. It is an admirable addition to Westview’s excellent Dimensions of Philosophy series. Brisk, workmanlike chapters profile the usual suspects: behaviorism, the identity theory, mind as computer and as causal structure, mental causation, consciousness, mental (...) content, and reductive and nonreductive physicalism. Each chapter ends with a useful note on further readings. (shrink)

This paper seeks to overturn the claim that Cartesian arguments for dualism based on the conceivable separation of person and body lack warrant, since it is just as conceivable that persons are identical with their bodies as it is that persons and their bodies are distinct. If the thesis of the paper is cogent, then it is not as easy to imagine person-body identity as many anti-Cartesians suppose.

If you have become as discouraged as I have in the past in the struggle to decipher what philosophers are really up to, then this book will provide very helpful explanations. It is not a book that can be read through quickly, and it does require a fairly broad familiarity with the language of philosophy, however the effort to understand it is very well worth it. It is also not a book that reassures the kind of person who seeks to (...) avoid personal responsibility and self-direction. It dissolves ordinary refuges of transcendently comforting words rather than promotes them. That is, this book is for fiercely independently-minded individuals. If you want to not be misled into the same mistakes philosophers have been making over the past two millennia, then this book is essential towards your quest. (shrink)
