David Kellogg Lewis (1941-2001) was one of the most influential philosophers of the twentieth century. He made significant contributions to almost every area of analytic philosophy including metaphysics, philosophy of language, philosophy of mind, and philosophy of science, and set the agenda for various debates in these areas which carry on to this day. In several respects he remains a contemporary figure, yet enough time has now passed for historians of philosophy to begin to study his place in twentieth (...) century thought. His philosophy was constructed and refined not just through his published writing, but also crucially through his life-long correspondence with fellow philosophers, including leading figures such as D.M. Armstrong, Saul Kripke, W.V. Quine, J.J.C. Smart, and Peter van Inwagen. His letters formed the undercurrent of his published work and became the medium through which he proposed many of his well-known theories and discussed a range of philosophical topics in depth. A selection of his vast correspondence over a 40-year period is presented here across two volumes. The letters offer an organic story of the origins, development, breadth, and depth of his philosophy in its historical context, as well as a glimpse into the influence of his many interlocutors."-- OCLC OLUC.

Counterfactuals is David Lewis' forceful presentation of and sustained argument for a particular view about propositions which express contrary to fact conditionals, including his famous defense of realism about possible worlds and his theory of laws of nature.

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.

What knowledge would suffice to yield an interpretation of an arbitrary utterance of a language when such knowledge is based on evidence plausibly available to a nonspeaker of that language? it is argued that it is enough to know a theory of truth for the language and that the theory satisfies tarski's 'convention t' and that it gives an optimal fit to data about sentences held true, Under specified conditions, By native speakers.

This is the first of a three-volume collection of David Lewis's most recent papers in all the areas to which he has made significant contributions. The purpose of this collection (and the two volumes to follow) is to disseminate even more widely the work of a preeminent and influential late twentieth-century philosopher. The papers are now offered in a readily accessible format. This first volume is devoted to Lewis's work on philosophical logic from the last twenty-five years. The topics (...) covered include: deploying the methods of formal semantics from artificial formalised languages to natural languages, model-theoretic investigations of intensional logic, contradiction, relevance, the differences between analog and digital representation, and questions arising from the construction of ambitious formalised philosophical systems. The volume will serve as an important reference tool for all philosophers and their students. (shrink)

It is advisable to treat some sorts of discourse about fiction with the aid of an intensional operator "in such-And-Such fiction...." the operator may appear either explicitly or tacitly. It may be analyzed in terms of similarity of worlds, As follows: "in the fiction f, A" means that a is true in those of the worlds where f is told as known fact rather than fiction that differ least from our world, Or from the belief worlds of the community in (...) which the fiction originated.

In Empirical Realism David K. Clark asks, simply: is there a moral structure to the universe?

A solution to the problem of intrinsic change for enduring things should meet three conditions. It should not replace monadic intrinsic properties by relations. It should not replace the having simpliciter of properties by standing in some relation to them. It should not rely on an unexplained notion of having an intrinsic property at a time. Johnston's solution satisfies the first condition at the expense of the second. Haslanger's solution satisfies the first and second at the expense of the third.

This volume is devoted to Lewis's work in metaphysics and epistemology. Topics covered include properties, ontology, possibility, truthmaking, probability, the mind-body problem, vision, belief, and knowledge. The purpose of this collection, and the volumes that precede and follow it, is to disseminate more widely the work of an eminent and influential contemporary philosopher. The volume will serve as a useful work of reference for teachers and students of philosophy.

is the second-order theory of the part-whole relation. It can express such hypotheses about the size of Reality as that there are inaccessibly many atoms. Take a non-empty class to have exactly its non-empty subclasses as parts; hence, its singleton subclasses as atomic parts. Then standard set theory becomes the theory of the member-singleton function—better, the theory of all singleton functions—within the framework of megethology. Given inaccessibly many atoms and a specification of which atoms are urelements, a singleton function exists, (...) unique up to isomorphism.

The debate between Jurgen Habermas and Charles Taylor is reflective of the enduring conflict between liberal philosophy with its emphasis upon freedom, equality, and legal rights, and Aristotelianism with its accent upon the cultivation of virtue, personal responsibility and shared notions of the Good. Though grounded in opposite ends of the philosophical spectrum, both men remain critical of the burgeoning effects of instrumental rationality and the social atomization and anomie it continues to generate; both understand the extent to which the (...) self is a social construct and the role of interpersonal intersubjectivity in the development of their individual and collective identities; both argue for the centrality of certain goods in maintaining a minimal degree of social cohesion; and both affirm that the crucial feature of human life is communication and its dialogical character. ;To overcome the adverse manifestations of our positivistic ethos with its over-reliance upon purposive-instrumental reason, each has responded with a countervailing notion of rationality---"phronesis" or Aristotelian practical reason for Taylor and "communicative reason" for Habermas. Each's choice of reason has led to profound differences in their respective notions of the self as well as fundamental incongruities in their moral and political philosophies. In the interest of preserving the autonomy and integrity of the individual while yet affirming universal justice, Habermas argues for the formalism of a "proceduralistic" ethics. Taylor, on the other hand, advocates a "substantialist" one, a communal ethics that arises from out of people's deepest moral intuitions; an ethics bound up with historical values and ideals that stresses the cultivation of virtue and shared notions of the common good. ;I argue that although Habermas's "communicative action" with its focus upon intersubjective communication helps to bridge the competing philosophies of communitarianism and classical liberalism, a basic incommensurability still persists. However, rather than being mutually exclusive, there needs to be a creative, dialectical tension maintained between them whereby each continues to inform and influence the other. In this way, a postmodern ethics rooted in dialogue and communication can be constructed which maintains people's integrity and autonomy while similarly addressing their multiple needs and concerns, but also an ethics grounded in one's deepest moral intuitions which remains sensitive to the concrete, historical, and particularistic distinctions which differentiate their identities.

This volume is devoted to Lewis's work in ethics and social philosophy. Topics covered include the logic of obligation and permission; decision theory and its relation to the idea that beliefs might play the motivating role of desires; a subjectivist analysis of value; dilemmas in virtue ethics; the problem of evil; problems about self-prediction; social coordination, linguistic and otherwise; alleged duties to rescue distant strangers; toleration as a tacit treaty; nuclear warfare; and punishment. This collection, and the two preceding volumes, (...) will disseminate more widely the work of an eminent and influential contemporary philosopher. (shrink)

This is the second volume of philosophical essays by one of the most innovative and influential philosophers now writing in English. Containing thirteen papers in all, the book includes both new essays and previously published papers, some of them with extensive new postscripts reflecting Lewis's current thinking. The papers in Volume II focus on causation and several other closely related topics, including counterfactual and indicative conditionals, the direction of time, subjective and objective probability, causation, explanation, perception, free will, and rational (...) decision. Throughout, Lewis analyzes global features of the world in such a way as to show that they might turn out to supervene on the spatiotemporal arrangement of local qualities. (shrink)

Henderson and Horgan set out a broad new approach to epistemology. They defend the roles of the a priori and conceptual analysis, but with an essential empirical dimension. 'Transglobal reliability' is the key to epistemic justification. The question of which cognitive processes are reliable depends on contingent facts about human capacities.

In Chinese Confucian medical ethics, the principle of autonomy has not been recognized. Instead, the basic values of medical practice are compassion and humaneness. Patient autonomy however lies at the foundation of Western medical ethics in general and research ethics in particular. In the modern world of biotechnology, what happens when medical research is carried out in an East Asian society? Should the society adopt principles of Western medical ethics? Or can resources to ensure ethical research be found in Confucian (...) ethics? I consider answers to these questions in the context of a recent case of unethical research in Singapore. (shrink)

This book brings together in one volume some of the very latest developments in moral psychology that were presented at a major American conference in 2004. Moral psychology is a broad area at the intersection of moral philosophy and philosophy of mind and action. Essays in this collection deal with most of the central issues in moral psychology that are of interest to a large number of philosophers today, including important questions in normative ethical theory, meta-ethics, and applied ethics.

The aim of the paper is to show that there are actions which are non-intentional. An account is first given which links intentional and unintentional action to acting for a reason, or appropriate causation by an intention. Mannerisms and habitual actions are then presented as examples of behavior which are actions, but which are not done in the course of acting for a reason. This account has advantages over that of Hursthouse's "arational actions," which are allegedly intentional actions done for (...) no reason at all. Finally, one consequence of neglecting non-intentional action is discussed to illustrate its importance. (shrink)
