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.

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)

_ Convention_ was immediately recognized as a major contribution to the subject and its significance has remained undiminished since its first publication in 1969. Lewis analyzes social conventions as regularities in the resolution of recurring coordination problems-situations characterized by interdependent decision processes in which common interests are at stake. Conventions are contrasted with other kinds of regularity, and conventions governing systems of communication are given special attention.

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)

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.

In his note "can there be vague objects?" ("analysis", 1978), Gareth evans presents a purported proof that there can be no vague identity statements. Some readers think that evans endorses the proof and its false conclusion. Not so. His point is that those who put vagueness in the world, Rather than in language, Will have no way to fault the proof and no way to escape the false conclusion.

Many years ago, C.B. Martin drew our attention to the possibility of ‘finkish’ dispositions: dispositions which, if put to the test would not be manifested, but rather would disappear. Thus if x if finkishly disposed to give response r to stimulus s, it is not so that if x were subjected to stimulus r, x would give response z; so finkish dispositions afford a counter‐example to the simplest conditional analysis of dispositions. Martin went on to suggest that finkish dispositions required (...) a theory of primitive causal powers; there, I think, he was mistaken. All that they require is an improved conditional analysis, and this improved analysis can be built upon whatever treatments of properties and of laws we may favour on other grounds. (shrink)

The void is deadly. If you were cast into a void, it would cause you to die in just a few minutes. It would suck the air from your lungs. It would boil your blood. It would drain the warmth from your body. And it would inflate enclosures in your body until they burst}.

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.

This outline for a paper, which develops a compatibilist analysis of abilities, was completed by David Lewis during his sabbatical in the Fall semester of 2000 and is dated 20 January 2001. Starting from the claim that it’s a “Moorean fact” that we are often able to do otherwise, Lewis provides a “simple proof of compatibilism.” He then presents his own account of abilities: S is able to A if and only if there are no obstacles to (...) their A-ing, where an obstacle is a “robust preventer”: something that would cause S not to A, and which “wouldn’t go away if things were just a little different.”.

There is no distinct correspondence theory of truth, truth is correspondence to fact. If facts are taken to be true propositions, we wind up with just another version of the correspondence theory's ostensible competitor, the redundancy theory of truth. If instead facts are taken to be Armstrong's states of affairs, or Tractarian facts, or Mellor's _facta<D>, we get a _truthmaker<D> principle, that for every truth there is a truthmaker; something whose existence implies the proposition in question. Truthmaker principles are interesting (...) and useful, but go far beyond truth as correspondence with fact, and so are not really theories of truth at all. (shrink)

Christianity teaches that whenever evil is done, God had ample warning. He could have prevented it, but He didn't. He could have stopped it midway, but He didn't. He could have rescued the victims of the evil, but - at least in many cases - He didn't. In short, God is an accessory before, during, and after the fact to countless evil deeds, great and small. An explanation is not far to seek. The obvious hypothesis is that the Christian God (...) is really some sort of devil. Maybe He is a devil as popularly conceived, driven' by malice. Or maybe He is unintelligibly capricious. Or maybe He is a fanatical artist who cares only for the aesthetic quality of creation - perhaps the abstract beauty of getting rich variety to emerge from a few simple laws, or perhaps the concrete drama of human life with all its diversity - and cares nothing for the good of the creatures whose lives are woven into His masterpiece. Oust as a tragedian has no business providing a happy end out of compassion for his characters.) But no; for Christianity also teaches that God is morally perfect and perfectly benevolent, and that He loves all of His creatures; and that these things are true in a sense not a million miles from the sense in which we attribute morality, benevolence, or love to one another.

If a guilty offender is justly sentenced to be punished and an innocent volunteer agrees to be punished instead, is that any reason to leave the offender unpunished? In the context of mundane criminal justice, we mostly think not. But in a religious context, some Christians do believe in penal substitution as a theory of the atonement. However, it is not just these Christians, but most of us, who are of two minds. If the punishment is an imprisonment or death, (...) we do not believe in penal substitution. But if it’s a fine, even a big fine, we mostly do. (shrink)

D. H. Hodgson has argued that among highly knowledgeable and rational act-Utilitarians there is no non-Circular reason to be truthful or to expect truthfulness from others; wherefore these utilitarians forfeit the benefits of communication. I reply that hodgson goes wrong by tacitly assuming that his utilitarians have no premises to reason from except those that hodgson lays down in specifying the example under consideration.

David Lewis's untimely death on 14 October 2001 deprived the philosophical community of one of the outstanding philosophers of the 20th century. As many obituaries remarked, Lewis has an undeniable place in the history of analytical philosophy. His work defines much of the current agenda in metaphysics, philosophical logic, and the philosophy of mind and language. This volume, an expanded edition of a special issue of the Australasian Journal of Philosophy, covers many of the topics for which (...) Lewis was well known, including possible worlds, counterpart theory, vagueness, knowledge, probability, essence, fiction, laws, conditionals, desire and belief, and truth. Many of the papers are by very established philosophers; others are by younger scholars including many he taught. The volume also includes Lewis's Jack Smart Lecture at the Australian National University, "How Many Lives has Schrodinger's Cat?," published here for the first time. Lewisian Themes will be an invaluable resource for anyone studying Lewis's work and a major contribution to the many topics that he mastered. (shrink)

The life-long correspondence of David K. Lewis, one of the most influential philosophers of the twentieth century, reveals the development, breadth, and depth of his philosophy in its historical context. The first of this two volume collection of letters focuses on his contributions to metaphysics, arguably where he made his greatest impact.

The aim of this paper is to make a comparison between two philosophical theories on convention, totally independent from each other, and produced by two thinkers of this century yet totally unknown to each other, in order to assess to what extent both theories meet the same facts or are verified by the same features. The result of this inquiry is that each theory is autonomous, but that both theories are quite compatible with each other, that they even fairly coincide (...) with each other, and that there where they emphasize different aspects of a convention they are complementary to each other. In a general introductory paragraph we lay stress upon the distinction between something conventional and something arbitrary and assign a place to conventionalism between rationalism and relativism. In the second part of the paper we examine D. K. Lewis's conception and analysis of the notion of a convention, which he defines in terms of the theory of games of pure coordination, in terms of coordination equilibrium, of orders of mutual expectations, of preferences and of regularities. In the third part of the paper we show that Dupréel's sociological concept of 'being of one mind' is the analogue of Lewis's definition. We also compare Lewis's remarks on the phenomenon of the imitation with Dupréel's theory of the consolidation and endorse the latter's view that a convention has a creative function so that it cannot be reduced to being a pure sign of something else. In the fourth part of our paper we analyze the relation between value and convention and claim that in Dupréel's philosophy the main values may not be identified with conventions. Lastly we justify our conclusion as already stated at the beginning of this summary. (shrink)

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.
