In recent years a number of writers have defended and attacked various features of structural, or neo-realist theories of international politics. Few, however, have quarrelled with one of the most foundational features of neorealist theory: its assumptions about the nature of science and scientific theories. In this essay I assess the views of science underlying much neorealist theory, especially as they are articulated in the work of Kenneth Waltz. I argue not only that neorealist theories rest on assumptions about science (...) and theory that have been questioned by postpositivist philosophers and historians of science, but also that the failure to consider the work of these writers yields theories of international politics that are deficient in several respects: they are weak theories in the sense that they cannot illuminate crucial features of international politics, they presuppose and sustain a narrow view of power and power relations, they reify practices and relations in the international arena and they offer little promise of producing the sort of Copernican Revolution for which Waltz called (or, more modestly, even a minimally satisfactory theory of international politics). In light of these shortcomings, I sketch an alternative approach to the study of international affairs, one that has been termed prototype studies. I contend that such an approach provides scholars with a rigorous way of studying international politics, without being a theoretical science. (shrink)
I insist that I was able to raise my hand, and I acknowledge that a law would have been broken had I done so, but I deny that I am therefore able to break a law. To uphold my instance of soft determinism, I need not claim any incredible powers. To uphold the compatibilism that I actually believe, I need not claim that such powers are even possible. My incompatibilist opponent is a creature of fiction, but he has his prototypes (...) in real life. He is modeled partly after Peter van Inwagen and partly on myself when I first worried about van Inwagen's argument against compatibilism. (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.
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)
Several alleged counterexamples to the definition of 'intrinsic' proposed in Rae Langton and David Lewis, 'Defining "Intrinsic"', are unconvincing. Yet there are reasons for dissatisfaction, and room for improvement. One desirable change is to raise the standard of non-disjunctiveness, thereby putting less burden on contentious judgements of comparative naturalness. A second is to deal with spurious independence by throwing out just the disjunctive troublemakers, instead of throwing out disjunctive properties wholesale, and afterward reinstating those impeccably intrinsic disjunctive properties that (...) are not troublemakers. (The second of these changes makes the first more affordable.) A third, suggested by Brian Weatherson, would be to invoke the general principle that the intrinsic and the extrinsic characters of things are independent, rather than relying just on one special case of this principle; but it is none too obvious how to do this.

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.
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)

This book takes up the central themes of Aristotle's metaphysical theory and the various transformations they undergo prior to their full expression in the Metaphysics. Aristotle's metaphysics is bedevilled by classic puzzles involving such notions as form, predication, universal, and substance, which result from his attempt to adapt the various requirements on primary substance developed in his earlier works so that they fit the very different metaphysical picture in his later work. Professor Lewis argues that Aristotle is himself aware (...) of most if not all of these difficulties and in the Metaphysics works hard to ensure the coherence of his theory. He presents Aristotle's views as a formal theory complete with axioms, definitions, and theorems. (shrink)
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)
Jaegwon Kim définissait une propriété intrinsèque comme une propriété compatible avec le fait que l'objet ne serait accompagné d'aucun autre être contingent. Mais cela impliquerait que la solitude serait une propriété intrinsèque, or c'est une propriété extrinsèque. Les auteurs définissent une propriété intrinsèque de base comme une propriété indépendante de la solitude et de l'accompagnement et qui n'est ni une propriété disjonctive ni une négation de propriété disjonctive. Deux doubles intrinsèques sont des objets qui ont toutes les mêmes propriétés intrinsèques (...) de base. Une propriété intrinsèque peut dès lors être définie comme une propriété qui ne peut jamais différer entre deux doubles. Cette définition est ensuite appliquée à différents problèmes. Si les lois de la nature sont absolument nécessaires ou qu'un être nécessaire existe, de nombreuses connexions deviendraient alors des propriétés intrinsèques et il sera nécessaire de conserver un sens à la possibilité que ces connexions nécessaires auraient pu ne pas exister. Les propriétés dispositionnelles seront intrinsèques ou non, selon la conception des lois de la nature. Il est possible de suivre les conséquences de la définition, en amendant éventuellement d'autres concepts. La définition peut aussi s'appliquer aux relations. Les auteurs comparent aussi leur définition à d'autres définitions antérieurement données par David Lewis et Peter Vallentyne. Jaegwon Kim had defined an intrinsic property as a property that does not imply that the object is accompanied by another contingent being. But this would imply that loneliness would be an intrinsic property, whereas it is an extrinsic property. The authors define a basic intrinsic property as a property independent from accompaniment or loneliness and which is neither a disjunctive property nor a negation of a disjunctive property. Two intrinsic duplicates are objects which have all the same basic intrinsic properties. An intrinsic property can be defined as a property which can never differ between duplicates. This definition is then applied to different problems. If laws of nature are necessary or if a necessary being exists, many connections will turn out to be intrinsic properties and it will be necessary to keep a sense of possibility according to which those necessary connections could have not obtained. Dispositions will be intrinsic or extrinsic depending on the conception of the laws of nature. It is possible to follow this definition of intrinsicness if one amends other concepts. The definition can also be applied to relations. The article ends by comparing this definition with previous ones by David Lewis and Peter Vallentyne. (shrink)

In this paper, Tyson E. Lewis challenges the dominant theoretical and practical educational responses to globalization. On the level of public policy, Lewis demonstrates the limitations of both neoliberal privatization and liberal calls for rehabilitating public schooling. On the level of pedagogy, Lewis breaks with the dominant liberal democratic tradition which focuses on the cultivation of democratic dispositions for cosmopolitan citizenship. Shifting focus, Lewis posits a new location for education out of bounds of the common sense (...) of public versus private, nationalism versus cosmopolitanism, inclusion versus exclusion, human versus civil rights. This is the space of the commonwealth whose actors cannot be identified as ‘citizens’ but are rather the anonymous multitude. In conclusion, Lewis finds a model for organizing this commonwealth in the work of Ivan Illich, whose learning networks speak to the urgent political and pedagogical need for exodus from the conceptual vocabulary that defines much of the contemporary field of educational theory.

In this essay Tyson Lewis reevaluates Jean-Jacques Rousseau's assessment of the pedagogical value of fables in Emile's education using Giorgio Agamben's theory of poetic production and Thomas Keenan's theory of the inherent ambiguity of the fable. From this perspective, the “unreadable” nature of the fable that Rousseau exposed is not simply the result of a child's innocence or developmental immaturity, but is rather a structural quality of the fable as such. Moving from a discussion of Rousseau's description of the (...) fable and its relation to early childhood development, Lewis then telescopes outward into an analysis of Emile as a reenactment of the paradoxes of the fable. While Rousseau critiqued the pedagogical value of the fable, his own pedagogical project is informed by many of the qualities that he attributed to the fable. This return of the fable is enacted through Rousseau's writing on three interconnected levels: the question of the maxim, the paradox of truth, and the paradox of freedom. Lewis argues that if we take seriously the textually fabulous dimension of Emile, then the reader is left exposed to the very same anxieties as a child who is confronted with the ambiguity of the fable. In a concluding gesture, Lewis speculates about what Emile's fabulous dimension means for the practice of educational philosophy itself. (shrink)
Paul Lewis and Walter Gulick summarize and evaluate Mark Micthell’s new book, Michael Polanyi: The Art of Knowing, and Mitchell responds to their comments in this symposium article.
Heidegger Beyond Deconstruction argues that Heidegger's question of being cannot be separated from the question of nature and culture, and that the history of being describes the growing predominance of culture and technology over nature, resulting in today's environmental crisis. It proposes that we turn to Heidegger's thought in order fully to understand this crisis. In doing so it is necessary to retrieve those elements of his thought which are most maligned by Derridean deconstruction: the pastoral, the homely, the local. (...) In a world coming to terms with the destructive nature of ‘globalisation' and the networks of distribution and travel which lacerate the globe, we are witnessing a gradual return to the ‘locally produced', the ‘organic', the ‘micro-generation' of energy unplugged from the national and international grid: in other words, a return to the ‘near'. The necessities and problems inherent in this return, which the ‘environmental movement' must address, are already to be found in Heidegger's thought. Lewis confronts this thought with that of Lacan, Levinas, Žižek, and Marx in order to reinvent the element to which deconstruction usually confines it and bring it into a position from which to confront the most pressing ethical and political questions of today.

C. S. Lewis takes us on a profound journey through both heaven and hell in this engaging allegorical tale. Using his extraordinary descriptive powers, Lewis introduces us to supernatural beings who will change the way we think about good and evil.
Many contemporary philosophers accept Hume's Dictum (HD), according to which there are no metaphysically necessary connections between distinct, intrinsically typed entities. Tacit in Lewis's work is a potential motivation for HD, according to which one should accept HD as presupposed by the best account of the range of metaphysical possibilities---namely, a combinatorial account, applied to spatiotemporal fundamentalia. Here I elucidate and assess this Ludovician motivation for HD. After refining HD and surveying its key, recurrent role in Lewis’s work, (...) I present Lewis’s appeal to HD as providing a broadly axiomatic generating basis for the space of metaphysical modality, and canvas the prima facie advantages of the resulting combinatorial principle---HD (L-combinatorialism)---as being principled, extensionally adequate and modally reductive. Most criticisms of Lewis's combinatorialism have targeted seeming ways in which the theory overgenerates the desired space; I rather argue that HD (L-combinatorialism) seriously undergenerates the desired space in three different ways. For each way I argue that available means of overcoming the undergeneration either fail to close the gap, undermine the claim that HD (L-combinatorialism) is a principled generator of metaphysical modal space, undermine the reductive status of Lewis's combinatorialism, or call into question the truth of HD.

David Lewis's book 'On the Plurality of Worlds' mounts an extended defense of the thesis of modal realism, that the world we inhabit the entire cosmos of which we are a part is but one of a vast plurality of worlds, or cosmoi, all causally and spatiotemporally isolated from one another. The purpose of this article is to provide an accessible summary of the main positions and arguments in Lewis's book.
David Lewis's account of intentionality is a version of what he calls 'global descriptivism'. The rough idea is that the correct interpretation of one's total theory is the one (among the admissible interpretations) that come closest to making it true. I give an exposition of this account, as I understand it, and try to bring out some of its consequences. I argue that there is a tension between Lewis's global descriptivism and his rejection of a linguistic account of (...) the intentionality of thought. I distinguish some different senses in which Lewis's theory might permit, or be committed to, a kind of holism about intentional content, and I consider the sense in which Lewis's account might be said to be an internalist account, and the motivation for this kind of internalism.

A major criticism of David Lewis’ counterfactual theory of causation is that it allows too many things to count as causes, especially since Lewis allows, in addition to events, absences to be causes as well. Peter Menzies has advanced this concern under the title “the problem of profligate causation.” In this paper, I argue that the problem of profligate causation provides resources for exposing a tension between Lewis’ acceptance of absence causation and his modal realism. The result (...) is a different problem of profligate causation—one that attacks the internal consistency of Lewisian metaphysics rather than employing common sense judgments or intuitions that conflict with Lewis’ extensive list of causes. (shrink)
David Lewis claims that his theory of modality successfully reduces modal items to nonmodal items. This essay will clarify this claim and argue that it is true. This is largely an exercise within ‘Ludovician Polycosmology’: I hope to show that a certain intuitive resistance to the reduction and a set of related objections misunderstand the nature of the Ludovician project. But these results are of broad interest since they show that would-be reductionists have more formidable argumentative resources than is (...) often thought. Lewis’s reduction depends on a set of methodological commitments each of which is fairly plausible or at least currently popular, and none of which is particular to modality. The choice of which of these commitments to reject I leave to the discerning antireductionist. The essay proceeds as follows: §1 discusses reduction generally and one or two relevant puzzles; §2 discusses Lewis’s reduction in particular; the longest section, §3 replies to four objections.

In “What Puzzling Pierre Does not Believe”, Lewis ([4], 412‐4) argues that the sentences (1) Pierre believes that London is pretty and (2) Pierre believes that London is not pretty both truly describe Kripke’s well‐known situation involving puzzling Pierre ([3]). Lewis also argues that this situation is not one according to which Pierre believes either the proposition (actually) expressed by (3) London is pretty or the proposition (actually) expressed by (4) London is not pretty. These claims, Lewis (...) suggests, provide a starting point from which a correct resolution of Kripke’s puzzles about belief ([3]) can be developed. At the end of his paper ([4], p. 414‐7), Lewis considers and replies to a number of potential objections to his position. According to one of these, Lewis’s contentions regarding (1)‐(4) cannot all be true because ‘believes that’ and ‘believes the proposition that’ are synonymous. Although the objection Lewis considers is unsound and his response to it correct, a minor variant of that objection provides significant reason to be skeptical of his contentions. This variant, moreover, is not persuasively addressed by anything either Lewis or any other well‐known defender of this sort of view (such as Stalnaker [8]) has had to say on the matter. All of this is relevant, moreover, not 2 only when it comes to assessing Lewis’s contentions regarding (1)‐ (4), but also when it comes to drawing lessons from certain standard objections to the view that the propositional objects of belief and assertion are sets of metaphysically possible worlds.

This paper examines a promising probabilistic theory of singular causation developed by David Lewis. I argue that Lewis' theory must be made more sophisticated to deal with certain counterexamples involving pre-emption. These counterexamples appear to show that in the usual case singular causation requires an unbroken causal process to link cause with effect. I propose a new probabilistic account of singular causation, within the framework developed by Lewis, which captures this intuition.
Helen Beebee has recently argued that David Lewis’s account of compatibilism, so-called local miracle compatibilism (LMC), allows for the possibility that agents in deterministic worlds have the ability to break or cause the breaking of a law of nature. Because Lewis’s LMC allows for this consequence, Beebee claims that LMC is untenable and subsequently that Lewis’s criticism of van Inwagen’s Consequence Argument for incompatibilism is substantially weakened. I review Beebee’s argument against Lewis’s thesis and argue (...) that Beebee has not refuted LMC and concomitantly has not demonstrated that Lewis’s criticism of the Consequence Argument fails.

In his metaphysical summa of 1986, The Plurality of Worlds, David Lewis famously defends a doctrine he calls ‘modal realism’, the idea that to account for the fact that some things are possible and some things are necessary we must postulate an infinity possible worlds, concrete entities like our own universe, but cut off from us in space and time. Possible worlds are required to account for the facts of modality without assuming that modality is primitive – that there (...) are irreducibly modal facts. We argue that on one reading, Lewis’s theory licenses us to assume maverick possible worlds which spread through logical space gobbling up all the rest. Because they exclude alternatives, these worlds result in contradictions, since different spread worlds are incompatible with one another. Plainly Lewis’s theory must be amended to exclude these excluders. But, we maintain, this cannot be done without bringing in modal primitives. And once we admit modal primitives, bang goes the rationale for Lewis’s modal realism. (shrink)
In this paper, we review Keith Lehrer’s account of the basing relation, with particular attention to the two cases he offered in support of his theory, Raco (Lehrer, Theory of knowledge, 1990; Theory of knowledge, (2nd ed.), 2000) and the earlier case of the superstitious lawyer (Lehrer, The Journal of Philosophy, 68, 311–313, 1971). We show that Lehrer’s examples succeed in making his case that beliefs need not be based on the evidence, in order to be justified. These cases (...) show that it is the justification (rather than the belief) that must be based in the evidence. We compare Lehrer’s account of basing with some alternative accounts that have been offered, and show why Lehrer’s own account is more plausible. (shrink)
My aim is to rekindle interest in David Lewis's (1983) infamous but neglected Mixed Theory of mental states. The Mixed Theory is a mix of physicalism and functionalism designed to capture the intuitions that both Martians and abnormal human Madmen can be in pain. The Mixed Theory is widely derided. But I offer a new development of the Mixed Theory immune to its most prominent objections. In doing so, I uncover a new motivation for the Mixed Theory: its unique (...) ability to explain cases in which it is plausibly indeterminate whether something is in pain. The Mixed Theory, whether or not it is ultimately correct, at least deserves renewed attention. (shrink)
This paper examines a special kind of social preference, namely a preference to do one's part in a mixed-motive setting because the other party expects one to do so. I understand this expectation-based preference as a basic reactive attitude (Strawson 1974). Given this, and the fact that expectations in these circumstances are likely to be based on other people's preferences, I argue that in cooperation a special kind of equilibrium ensues, which I call a loop, with people's preferences and expectations (...) mutually cross-referring. As with a Lewis-norm, the loop can get started in a variety of ways. It is self-sustaining in the sense that people with social preferences have sufficient reason not to deviate. (shrink)
By the early 1970s, and continuing through 2001, David Lewis and Saul Kripke had taken over W.V.O. Quine’s leadership in metaphysics, epistemology, philosophy of language, and philosophical logic in the English-speaking world. Quine, in turn, had inherited his position in the early 1950s from Rudolf Carnap, who had been the leading logical positivist -- first in Europe, and, after 1935, in America. A renegade positivist himself, Quine eschewed apriority, necessity, and analyticity, while (for a time) adopting a holistic version (...) of verificationism. Like Carnap, he placed philosophical logic and the philosophy of science at the center of philosophy. (shrink)
There are two parts to Lewis's account of the de se. First there is the idea that the objects of de se thought (and, by extension of de dicto thought too) are properties, not propositions. This is the idea that is center-stage in Lewis's discussion. Second there is the idea that the relation that thinkers bear to these properties is that of self-ascription. It is crucial to LewisÕs account that this is understood as a fundamental, unanalyzable, notion: self-ascription (...) of a property is not ascription of a property to the self, on a par with ascription to someone else. This has been overlooked in much recent discussion, especially when Lewis's account is understood in terms of centered worlds. When it is back in focus it brings problems. An almost Cartesian starting point is required; and first-person plural ascriptions, and those with first person pronouns other than in subject position, become unmanageably complex. (shrink)
Recently, new life has been breathed into the ancient philosophical topic of skepticism. The subject of some of the best and most provocative work in contemporary philosophy, skepticism has been addressed not only by top epistemologists but also by several of the world's finest philosophers who are most known for their work in other areas of the discipline. Skepticism: A Contemporary Reader brings together the most important recent contributions to the discussion of skepticism. Covering major approaches to the skeptical problem, (...) it features essays by Anthony Brueckner, Keith DeRose, Fred Dretske, Graeme Forbes, Christopher Hill, David Lewis, Thomas Nagel, Robert Nozick, Hilary Putnam, Ernest Sosa, Gail Stine, Barry Stroud, Peter Unger, and Ted Warfield. The book opens with a thorough introduction that outlines the skeptical problem, explains the dominant responses to skepticism, and discusses the strengths, weaknesses, and unresolved issues of each response, providing undergraduate students and nonphilosophers with the background and context necessary to understand the essays. Skepticism: A Contemporary Reader serves as an ideal text for courses in epistemology and skepticism and will also appeal to professional philosophers and interested general readers. (shrink)
David Lewis's approach to analysing truth in fiction, significantly amended by 'Postscripts' in 1983, has been widely criticized on three main grounds, and it seems fair to say that nearly every writer on the subject thinks that one of these grounds is sufficient to show that Lewis is mistaken. I argue that with some minor revision, Lewis's approach survives all extant objections. Indeed, I judge the Lewis approach to be even more successful than Lewis himself (...) seems to think. (shrink)
The epistemology of modality is gradually coming to play a central role in general discussions about modality. This paper is a contribution in this direction, in particular I draw a comparison between Lewis’s Modal realism and Timothy Williamson’s recent account of modality in terms of counterfactual thinking. In order to have criteria of evaluation, I also formulate four requirements which are supposed to be met by any theory of modality to be epistemologically adequate.
Some argue that Lewisian realism fails as a reduction of modality because in order to meet some criterion of success the account needs to invoke primitive modality. I defend Lewisian realism against this charge; in the process, I hope to shed some light on the conditions of success for a reduction. In §1 I detail the resources the Lewisian modal realist needs. In §2 I argue against Lycan and Shalkowski’s charge that Lewis needs a modal notion of ‘world’ to (...) ensure that worlds correspond to possibilities. In §3 I respond to Divers and Melia’s objection that Lewis needs to invoke primitive modality to give a complete account of what worlds there are. In §4 I ask what it is for a notion to ‘involve’ modality. I conclude that the question is either in bad standing or at best offers little traction on the debate, and propose a different way of assessing when materials are appropriately included in a reductive base.

The aim of this paper is make a contribution to the ongoing search for an adequate concept of the a priori element in scientific knowledge. The point of departure is C.I. Lewis’s account of a pragmatic a priori put forward in his "Mind and the World Order" (1929). Recently, Hasok Chang in "Contingent Transcendental Arguments for Metaphysical Principles" (2008) reconsidered Lewis’s pragmatic a priori and proposed to conceive it as the basic ingredient of the dynamics of an embodied (...) scientific reason. The present paper intends to further elaborate Chang’s account by relating it with some conceptual tools from cognitive semantics and certain ideas that first emerged in the context of the category-theoretical foundations of mathematics.

In 'How Many Lives Has Schrödinger's Cat?' David Lewis argues that the Everettian no-collapse interpretation of quantum mechanics is in a tangle when it comes to probabilities. This paper aims to show that the difficulties that Lewis raises are insubstantial. The Everettian metaphysics contains a coherent account of probability. Indeed it accounts for probability rather better than orthodox metaphysics does.
David Lewis is widely credited with the first formulation of common knowledge and the first rigorous analysis of convention. However, common knowledge and convention entered mainstream game theory only when they were formulated, later and independently, by other theorists. As a result, some of the most distinctive and valuable features of Lewis' game theory have been overlooked. We re-examine this theory by reconstructing key parts in a more formal way, extending it, and showing how it differs from more (...) recent game theory. In contrast to current theories of common knowledge, Lewis' theory is based on an explicit analysis of the modes of reasoning that are accessible to rational individuals and so can be used to analyse the genesis of common knowledge. Lewis' analysis of convention emphasises the role of inductive reasoning and of salience in the maintenance of conventions over time.

David Lewis famously takes mereology “to be perfectly understood, unproblematic, and certain” (1991, 75). It is central to his thought, appearing in his discussions of set theory, modality, vagueness, structural universals, and elsewhere. He held views not only about how composition works and when it occurs, but also about the role of mereology in philosophy. In this essay, I will proceed by articulating four theses that Lewis holds about composition. (I would call them the four U’s, if only (...) ‘unguilty’ were a word!) Three of them are familiar; Lewis himself explicitly articulates and relies upon them. The fourth remains implicit, but it is nonetheless important. Here they are: Composition is unique —the same things cannot have two different fusions. Composition is unrestricted —any two things whatsoever have a fusion. (shrink)
The most important theories in fundamental physics, quantum mechanics and statistical mechanics, posit objective probabilities or chances. As important as chance is there is little agreement about what it is. The usual “interpretations of probability” give very different accounts of chance and there is disagreement concerning which, if any, is capable of accounting for its role in physics. David Lewis has contributed enormously to improving this situation. In his classic paper “A Subjectivist's Guide to Objective Chance” he described a (...) framework for representing single case objective chances, showed how they are connected to subjective credences, and sketched a novel account what they are within his Humean account of scientific laws. Here I will describe these contributions and add a little to them. (shrink)
Derek Parfit's “reductionist” account of personal identity (including the rejection of anything like a soul) is coupled with the rejection of a commonsensical intuition of essential self-unity, as in his defense of the counter-intuitive claim that “identity does not matter.” His argument for this claim is based on reflection on the possibility of personal fission. To the contrary, Simon Blackburn claims that the “unity reaction” to fission has an absolute grip on practical reasoning. Now David Lewis denied Parfit's claim (...) that reductionism contravenes common sense, so I revisit the debate between Parfit and Lewis, showing why Parfit wins it. Is reductionism about persons then inherently at odds with the unity reaction? Not necessarily; David Velleman presents a reductionist theory according to which fission does not conflict with the unity reaction. Nonetheless, relying on the distinction between person level descriptions of first-person states and the first-person perspective itself, I argue that Velleman's theory does not eliminate fission-based conflict with the unity reaction.

Lewis's work on causation was governed by a familiar methodological approach: the aim was to come up with an account of causation that would recover, in as elegant a fashion as possible, all of our firm “pre‐theoretic” intuitions about hypothetical cases. That methodology faces an obvious challenge, in that it is not clear why anyone not interested in the semantics of the English word “cause” should care about its results. Better to take a different approach, one which treats our (...) intuitions about cases merely as guides in the construction of a causal concept or concepts that will serve some useful theoretical purpose. I sketch one central such purpose, suggesting, first, that an account of causation that, like Lewis's, gives a central role to counterfactuals is well‐suited to fulfill it, and, second, that the most famous pre‐emption‐based counterexamples to a counterfactual account yield an important constraint on a successful account.

Lewis has argued that quasi-realism is fictionalism. Blackburn denies this, offering reasons which rely on a descriptive reading of quasi-realism. This note offers a different, more general argument against Lewis's claim, available to prescriptive as well as descriptive quasi-realists.
It is sometimes claimed (e.g., by Sider (2001a,b); Holton (2003); Stalnaker (2004); Williams (2007); Weatherson (2003, 2010)) that a theory of predicate meaning that assigns a central role to naturalness is either (a) Lewisian, (b) true, or (c) both. The theory in question is rarely developed in particularly great detail, but the rough intuitive idea is that the meaning of a predicate is the most natural property that is more-or-less consistent with the usage of the predicate. The point of this (...) note is to investigate whether a version of this idea could be true, and whether it could be properly attributed to Lewis. I’m going to mostly focus on the second question, but I think in such a way that light is shed on the first question. To anticipate the answer a little, I’m going to say that whether the use plus naturalness theory is plausibly attributed to Lewis (and is plausibly true) depends on what we want a theory of (predicate) meaning to do. Here are two very distinct tasks we could be engaged in. First, we could be investigating the metaphysics of meaning, and so be interested in how it is that a pattern of animal noises can come to have any kind of content at all. Second, we could be investigating the meaning of some particular term, where substantive claims about the meanings of other terms are presupposed in our inquiry. Call the first project metasemantics, and the second project applied semantics. I’m going to conclude that use plus naturalness is a plausible way to approach applied semantics. But it isn’t a great way to approach metasemantics. The problem is that once we crunch through the details, it’s impossible to disentangle a notion of “use” such that naturalness can be added to it to get a theory of meaning. Before we can get very far on any of these inquiries, we need to say a bit about what we mean by ‘naturalness’. Naturalness plays a lot of distinctive roles for Lewis. Some of these broadly metaphysical roles. These roles are the primary focus of (Lewis, 1983a).. (shrink)
It has been argued that a combination of game-theoretic semantics and independence-friendly (IF) languages can provide a novel approach to the conceptual foundations of mathematics and the sciences. I introduce and motivate an IF first-order modal language endowed with a game-theoretic semantics of perfect information. The resulting interpretive independence-friendly logic (IIF) allows to formulate some basic model-theoretic notions that are inexpressible in the ordinary quantified modal logic. Moreover, I argue that some key concepts of Kripke’s new theory of reference are (...) adequately modeled within IIF. Finally, I compare the logic IIF to David Lewis' counterpart theory, drawing some morals concerning the interrelation between metaphysical and semantic issues in possible-world semantics. (shrink)
The model-theoretic argument known as Putnam´s paradox threatens our notion of truth with triviality: Almost any world can satisfy almost any theory. Formal argument and intuition are at odds. David Lewis devised a solution according to which the very stucture of the world fixes how it is to be divided into elite classes which determine the reference of any true theory. Three claims are defended: Firstly, Lewis´ proposal must be completed by an account of successful referential intentions. Secondly, (...) contrary to Catherine Elgin´s criticism of Lewis, natural properties corresponding to elite classes may play a role in sound scientific inquiry. Thirdly, despite Bas van Fraassen´s objection that the sceptic cannot consistently maintain doubts about reference, there is a promising sceptical strategy of exploiting Putnam´s results which is answered by Lewis´ account.

This paper outlines Lewis’s favoured foundational account of linguistic representation, and outlines and briefly evaluates variations and modifications. Section 1 gives an opinionated exegesis of Lewis’ work on the foundations of reference—his interpretationism. I look at the way that the metaphysical distinction between natural and non-natural properties came to play a central role in his thinking about language. Lewis’s own deployment of this notion has implausible commitments, so in section 2 I consider variations and alternatives. Section 3 (...) briefly considers a buck-passing strategy involving fine-grained linguistic conventions. (shrink)
David Lewis's account of intentionality is a version of what he calls 'global descriptivism'. The rough idea is that the correct interpretation of one's total theory is the one (among the admissible interpretations) that come closest to making it true. I give an exposition of this account, as I understand it, and try to bring out some of its consequences. I argue that there is a tension between Lewis's global descriptivism and his rejection of a linguistic account of (...) the intentionality of thought. I distinguish some different senses in which Lewis's theory might permit, or be committed to, a kind of holism about intentional content, and I consider the sense in which Lewis's account might be said to be an internalist account, and the motivation for this kind of internalism. (shrink)
This paper considers two aspects of Lewis's metaphysics to which spatiotemporal relations appear central, with the aim of showing them to be less so. First, Lewis reluctantly characterises what it is for two things to be part of the same possible world in terms of an analogically spatiotemporal category of relations, rather than a wider natural external category. But Lewis's reason for restricting himself to the narrower category is unpersuasive. Second, Humean supervenience is formulated (...) with spatiotemporal relations at its core. But that seems negotiable. A reason for caring about this is that quantum mechanics is supposed to threaten Lewis's metaphysics by introducing natural external relations that are not (even analogically) spatiotemporal, hence the interest in how central spatiotemporal relations really are. (shrink)
Many writers have held that in his later work, David Lewis adopted a theory of predicate meaning such that the meaning of a predicate is the most natural property that is (mostly) consistent with the way the predicate is used. That orthodox interpretation is shared by both supporters and critics of Lewis's theory of meaning, but it has recently been strongly criticised by Wolfgang Schwarz. In this paper, I accept many of Schwarze's criticisms of the orthodox interpretation, and (...) add some more. But I also argue that the orthodox interpretation has a grain of truth in it, and seeing that helps us appreciate the strength of Lewis's late theory of meaning. References T. Bays.

David Lewis, Stewart Cohen, and Keith DeRose have proposed that sentences of the form S knows P are indexical, and therefore differ in truth value from one context to another.1 On their indexical contextualism, the truth value of S knows P is determined by whether S meets the epistemic standards of the speakers context. I will not be concerned with relational forms of contextualism, according to which the truth value of S knows P is determined by the standards (...) of the subject Ss context, regardless of the standards applying to the speaker making the knowledge claim. Relational contextualism is a form of normative relativism. Indexical contextualism is a semantic theory. When the subject is the speaker, as when S is the first person pronoun I, the two forms of contextualism coincide. But otherwise, they diverge. I critically examine the principal arguments for indexicalism, detail linguistic evidence against it, and suggest a pragmatic alternative. (shrink)
Like many discussions on the pros and cons of epistemic foundationalism, the debate between C.I. Lewis and H. Reichenbach dealt with three concerns: the existence of basic beliefs, their nature, and the way in which beliefs are related. In this paper we concentrate on the third matter, especially on Lewis’s assertion that a probability relation must depend on something that is certain, and Reichenbach’s claim that certainty is never needed. We note that Lewis’s assertion is prima (...) facie ambiguous, but argue that this ambiguity is only apparent if probability theory is viewed within a modal logic. Although there are empirical situations where Reichenbach is right, and others where Lewis’s reasoning seems to be more appropriate, it will become clear that Reichenbach’s stance is the generic one. This follows simply from the fact that, if P(E|G) > 0 and P(E|not-G) > 0, then P(E) > 0. We conclude that this constitutes a threat to epistemic foundationalism. (shrink)
According to David Lewis's extreme modal realism, every waythat a world could be is a way that some concretely existingphysical world really is. But if the worlds are physicalentities, then there should be a set of all worlds, whereasI show that in fact the collection of all possible worlds is nota set. The latter conclusion remains true even outside of theLewisian framework.
According to Lewis's modal realism, all ways the world could be are represented by possible worlds, and all possible worlds represent some way the world could be. That there are just the right possible worlds to represent all and only the ways the world could be is to be guaranteed by the principle of recombination. Lewis sketches the principle (put roughly: anything can co-exist with anything else), but does not spell out a precise version that generates just the (...) right possibilities. David Efird and Tom Stoneham have offered a principle that aims to do just that.In this paper, we argue that Efird's and Stoneham's principle of recombination is not successful – it fails to generate the right possibilities – but we also suggest ways that their account might be improved to solve the problem we raise. We also argue against Efird's and Stoneham's claim that the correct principle of recombination demonstrates the possibility of nothing concrete – it is true that their principle of recombination has models consistent with the existence of an empty world, but we only get the possibility of nothing if mereologically null individuals are possible. The Lewisian should only think mereologically null individuals are possible if he or she has some independent reason for believing in the possibility of an empty world, so the principle of recombination provides no new evidence for that possibility. We draw some morals from this for the correct way to formulate the principle of recombination. (shrink)
Consider a cat on a mat. On the one hand, there seem to be just one cat, but on the other there seem to be many things with as good a claim to being a cat, and there seems to be nothing in the vicinity with a better claim. Hence, the problem of the many. In his ‘Many, but Almost One,’ David Lewis offered two solutions. According to the first, only one of the many is indeed a cat, although (...) it is indeterminate exactly which one. According to the second, the many are all cats, but they are almost identical to each other, and hence they are almost one. For Lewis, the two solutions do not compete with each other but are mutually complementary, as each can assist the other. This paper has two aims: first to argue against the first of these two solutions, and then to defend the second as a self-standing solution from Lewis’s considerations to the contrary. In both parts I will assume the certainly plausible but also controversial view on the nature of vagueness, having it that vagueness is a kind of semantic indecision—of which Lewis himself is one of the main defenders. (shrink)
I argue for the claim that if Lewis’s regularity theory of laws were true, we could not know any positive law statement to be true. Premise 1: According to that theory, for any law statement true of the actual world, there is always a nearby world where the law statement is false (a world that differs with respect to one matter of particular fact). Premise 2: One cannot know a proposition to be true if it is false in a (...) nearby world (the epistemological safety principle). The conclusion that no law statement can be known to be true follows immediately from the two premises. (shrink)
I formulate a counterfactual version of the notorious ‘Ramsey Test’. Even in a weak form, this makes counterfactuals subject to the very argument that Lewis used to persuade the majority of the philosophical community that indicative conditionals were in hot water. I outline two reactions: to indicativize the debate on counterfactuals; or to counterfactualize the debate on indicatives.
In 'How Many Lives Has Schrödinger's Cat?' David Lewis argues that the Everettian no-collapse interpretation of quantum mechanics is in a tangle when it comes to probabilities. This paper aims to show that the difficulties that Lewis raises are insubstantial. The Everettian metaphysics contains a coherent account of probability. Indeed it accounts for probability rather better than orthodox metaphysics does.
The recent popularity of contextualist treatments of the key epistemic concepts has tended to obscure the differences that exist between the various kinds of contextualist theses on offer. The aim of this paper is to contribute towards rectifying this problem by exploring two of the main formulations of the contextualist position currently on offer in the literature—the 'semantic' contextualist thesis put forward by Keith DeRose and David Lewis, and the 'inferential' contextualist thesis advanced by Michael Williams. It is (...) argued that by evaluating these theses in the light of each other one can gain a deeper understanding of the contextualist position. In particular, it is argued that this relative evaluation highlights one interesting way in which contextualism might be developed. (shrink)
In this paper I reply to Keith Yandell's recent charge that Anselmian theists cannot also be Trinitarians. Yandell's case turns on the contention that it is impossible to individuate Trinitarian members, if they exist necessarily. Since the ranks of Anselmian Trinitarians includes the likes of Alvin Plantinga, Robert Adams, and Thomas Flint, Yandell's claim is of considerable interest and import. I argue, by contrast, that Anselmians can appeal to what Plantinga calls an essence or haecceity – a property essentially (...) unique to an object – to distinguish Trinitarian members. I go on to show that the main Yandellian objection to this individuative strategy is not successful. (shrink)
Keith Donnellan (1931 – ) began his studies at the University of Maryland, and earned his Bachelor’s degree from Cornell University. He stayed on at Cornell, earning a Master’s and a PhD in 1961. He also taught at there for several years before moving to UCLA in 1970, where he is currently Emeritus Professor of Philosophy. Donnellan’s work is mainly in the philosophy of language, with an emphasis on the connections between semantics and pragmatics. His most influential work was (...) his 1966 paper “Reference and Definite Descriptions”. In this paper, he challenges the canonical view, due to Bertrand Russell, about definite descriptions. Russell had argued that the proper semantic treatment of a definite description such as “the present king of France” was quantificational. Thus, a sentence like “the present king of France is bald” should be analyzed as “There exists one and only one entity x that is the present king of France, and x is bald”. Donnellan argues that in natural languages, there are actually two different kinds of uses of definite descriptions. Russell’s analysis picks out the “attributive” use of definite descriptions. When we use a definite description (“the F”) this way, we mean to make statements about the unique entity x that is F. However, Donnellan notes that we also sometimes use definite descriptions “referentially” to pick out a given entity and say something about it. To see this, imagine you are at a party where virtually everyone is drinking beer. However, you and your friend are observing a man in a corner of the room holding a martini glass. Unbeknownst to you, the man’s glass is filled with water. You turn to your friend and ask, “who is the man drinking a martini?” Suppose further that your friend knows that the man in question is Fred and that Fred’s glass is filled with water. According to the Russellian attributive analysis, such a question would amount to asking for the identity of the one and only one man drinking a martini. But the presupposition that there is a man drinking a martini is false, and so there should be no answer to the question.. (shrink)
In his ‘Causation as Influence’,1 David Lewis proposed a counterfactual theory of cause which was designed to improve on his previous account.2 Here I offer counter-examples to this new account, involving early preemption and late preemption, and a revised account, which is no longer an influence theory, that handles those counter-examples.
Lewis never saw philosophy of language as foundational in the way that many have. One of the most distinctive features of his work is the robust confidence that questions in metaphysics or mind can be addressed head on, and not through the lens of language.
