The twelve essays by Kendall Walton in this volume address a broad range of issues concerning the arts. Walton introduces an innovative account of aesthetic value, and explores relations between aesthetic value and values of other kinds. His classic 'Categories of Art' is included, as is 'Transparent Pictures', his controversial account of what is special about photographs. A new essay investigates the fact that still pictures are still, although some of them depict motion. New postscripts have been (...) added to several of the reprinted essays. (shrink)

Mimesis as Make-Believe is important reading for everyone interested in the workings of representational art.

It is a very great honor to address my friends and colleagues as president of the American Society for Aesthetics, an organization that plays a unique role in a field that is, at once, a major traditional branch of philosophy and also central to disciplines often regarded as remote from philosophy, as well as depending crucially on their contributions.

But to return to myself, I was thinking about my book in more modest terms, and it would even be a mistake to say that I was thinking of those who would read it as my readers. For they were not, as I saw it, my readers, so much as readers of their own selves, my book being merely one of those magnifying glasses of the sort the optician at Combray used to offer his customers; my book, but a book (...) thanks to which I would be providing them with the means of reading within themselves. With the result that I would not ask them to praise me or to denigrate me, only to tell me if it was right, if the words they were reading in themselves were really the ones I had written (possible divergences in this regard not necessarily always originating, it should be said, in my having been wrong, but sometimes in the fact that the reader’s eyes might not be of a type for which my book was suitable as an aid for self-reading).

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.

The book also includes an appendix of related writings by Lewis.

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)

Fundamentals of Critical Argumentation presents the basic tools for the identification, analysis, and evaluation of common arguments for beginners. The book teaches by using examples of arguments in dialogues, both in the text itself and in the exercises. Examples of controversial legal, political, and ethical arguments are analyzed. Illustrating the most common kinds of arguments, the book also explains how to evaluate each kind by critical questioning. Douglas Walton shows how arguments can be reasonable under the right dialogue conditions (...) by using critical questions to evaluate them. The book teaches by example, both in the text itself and in exercises, but it is based on methods that have been developed through the author's thirty years of research in argumentation studies.

Media argumentation is a powerful force in our lives. From political speeches to television commercials to war propaganda, it can effectively mobilize political action, influence the public, and market products. This book presents a new and systematic way of thinking about the influence of mass media in our lives, showing the intersection of media sources with argumentation theory, informal logic, computational theory, and theories of persuasion. Using a variety of case studies that represent arguments that typically occur in the mass (...) media, Douglas Walton demonstrates how tools recently developed in argumentation theory can be usefully applied to the identification, analysis, and evaluation of media arguments.

The paper considers contemporary models of presumption in terms of their ability to contribute to a working theory of presumption for argumentation. Beginning with the Whatelian model, we consider its contemporary developments and alternatives, as proposed by Sidgwick, Kauffeld, Cronkhite, Rescher, Walton, Freeman, Ullmann-Margalit, and Hansen. Based on these accounts, we present a picture of presumptions characterized by their nature, function, foundation and force. On our account, presumption is a modal status that is attached to a claim and has (...) the effect of shifting, in a dialogue, a burden of proof set at a local level. Presumptions can be analysed and evaluated inferentially as components of rule-based structures. Presumptions are defeasible, and the force of a presumption is a function of its normative foundation. This picture seeks to provide a framework to guide the development of specific theories of presumption. (shrink)

Abstract This paper addresses the role that argumentation schemes and argument visualization software tools can play in helping to find and counter objections to a given argument one is confronted with. Based on extensive analysis of features of the argumentation in these two examples, a practical four-step method of finding objections to an argument is set out. The study also applies the Carneades Argumentation System to the task of finding objections to an argument, and shows how this system has some (...) capabilities that are especially useful.

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, the defeasible argumentation scheme for practical reasoning (Walton 1990) is revised. To replace the old scheme, two new schemes are presented, each with a matching set of critical questions. One is a purely instrumental scheme, while the other is a more complex scheme that takes values into account. It is argued that a given instance of practical reasoning can be evaluated, using schemes and sets of critical questions, in three ways: by attacking one or more (...) premises of the argument, by attacking the inferential link between the premises and conclusion, or by mounting a counter-argument. It is argued that such an evaluation can be carried out in many cases using an argument diagram structure in which all components of the practical reasoning in the case are represented as premises, conclusions, and inferential links between them that can be labeled as argumentation schemes. This system works if every critical question can be classified as a assumption of or an exception to the original argument. However, it is also argued that this system does not work in all cases, namely those where epistemic closure is problematic because of intractable disputes about burden of proof. (shrink)

Recent work in artificial intelligence has increasingly turned to argumentation as a rich, interdisciplinary area of research that can provide new methods related to evidence and reasoning in the area of law. Douglas Walton provides an introduction to basic concepts, tools and methods in argumentation theory and artificial intelligence as applied to the analysis and evaluation of witness testimony. He shows how witness testimony is by its nature inherently fallible and sometimes subject to disastrous failures. At the same time (...) such testimony can provide evidence that is not only necessary but inherently reasonable for logically guiding legal experts to accept or reject a claim. Walton shows how to overcome the traditional disdain for witness testimony as a type of evidence shown by logical positivists, and the views of trial sceptics who doubt that trial rules deal with witness testimony in a way that yields a rational decision-making process.

Abstract Argumentation schemes are forms of reasoning that are fallible but correctable within a self-correcting framework. Their use provides a basis for taking rational action or for reasonably accepting a conclusion as a tentative hypothesis, but they are not deductively valid. We argue that teleological reasoning can provide the basis for justifying the use of argument schemes both in monological and dialogical reasoning. We consider how such a teleological justification, besides being inspired by the aim of directing a bounded cognizer (...) to true belief and correct choices, needs to take into account the attitudes of dialogue partners as well as normative models of dialogue and communicative activity types, in particular social and cultural settings.

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)

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.

Informal Logic is an introductory guidebook to the basic principles of constructing sound arguments and criticizing bad ones. Non-technical in approach, it is based on 186 examples, which Douglas Walton, a leading authority in the field of informal logic, discusses and evaluates in clear, illustrative detail. Walton explains how errors, fallacies, and other key failures of argument occur. He shows how correct uses of argument are based on sound strategies for reasoned persuasion and critical responses. Among the many (...) subjects covered are: forms of valid argument, defeasible arguments, relevance, appeals to emotion, personal attack, straw man argument, jumping to a conclusion, uses and abuses of expert opinion, problems in drawing conclusions from polls and statistics, loaded terms, equivocation, arguments from analogy, and techniques of posing, replying to, and criticizing questions. This new edition takes into account many new developments in the field of argumentation study that have occurred since 1989, many created by the author. Drawing on these developments, Walton includes and analyzes 36 new topical examples and also brings in recent work on argumentation schemes. Ideally suited for use in courses in informal logic and introduction to philosophy, this book will also be valuable to students of pragmatics, rhetoric, and speech communication. (shrink)

A "slippery slope argument" is a type of argument in which a first step is taken and a series of inextricable consequences follow, ultimately leading to a disastrous outcome. Many textbooks on informal logic and critical thinking treat the slippery slope argument as a fallacy. Walton argues that used correctly in some cases, they can be a reasonable type of argument to shift a burden of proof in a critical discussion, while in other cases they are used incorrectly. (...) class='Hi'>Walton identifies and analyzes four types of slippery slope argument. Walton presents guidelines that show how each type of slippery slope argument can be used correctly or incorrectly, using over fifty case studies of argumentation on controversial issues. These include abortion, medical research on human embryos, euthanasia, the decriminalization of marijuana, pornography, and censorship, and banning of American flag burning. (shrink)

most famous and, arguably, most important papers in modern aesthetics. Despite this, and the various references to it and discussions of it within the literature, there are no general commentaries on this essay. In addition to outlining a general framework for approaching the article, I identify and explicate the two main exegetical issues regarding it. The first concerns how to understand Walton's main thesis that the aesthetic character of artworks is determined, in part, by their ‘correct category’. I suggest (...) that the traditional interpretation of Walton's proposal is mistaken, and defend an alternative view at length. The second issue concerns the relationship between Walton's view and competing accounts of the aesthetics of artworks. Here I suggest that Walton's position is unique, contrasting the views of both typical formalists, on the one hand, and ordinary contextualists, on the other, in philosophically significant ways. Careful reflection on this particular issue helps reveal some very important distinctions among aesthetic theories, which have not been previously drawn or emphasized.

How is it that we can be moved by what we know does not exist? In this paper, I examine the so-called 'paradox of fiction', showing that it fatally hinges on cognitive theories of emotion such as Kendall Walton's pretend theory and Peter Lamarque's thought theory. I reject these theories and acknowledge the concept-formative role of genuine emotion generated by fiction. I then argue, contra Jenefer Robinson, that this 'éducation sentimentale' is not achieved through distancing, but rather through (...) the engagement of our emotions. Literature does this, I claim, by its uniquely perspicuous presentations of emotional concepts, and the cognitive pleasure that such 'presentations' prompt in us. (shrink)

Ornamentality is pervasive in the new media and it is related to their essential characteristics: dispersal, hypertextuality, interactivity, digitality and virtuality. I utilize Kendall Walton's theory of ornamentality in order to construe a puzzle pertaining to the new media. the ornamental erosion of information. I argue that insofar as we use the new media as conduits of real life, the excessive density of ornamental devices which is prevalent in certain new media environments, forces us to conduct our inquiries (...) under conditions of neustic uncertainty, that is, uncertainty concerning the kind of relationship we, the users, have to the propositional content mediated. I suggest that this puzzle calls upon us to consider what would be a viable logic of virtual discovery. (shrink)

The philosophical fiction of a neonate Crusoe is introduced to cast doubt on the interpretations and use of the private language argument to support a new psychology developed by the constructionists.

Many philosophers have maintained that secondary qualities are private mental entities. In this paper I use the discussions of H. A. Prichard, Berkeley and G. E. Moore on the status of secondary qualities to bring out the assumptions that underlie this view. One of these is that secondary qualities are particular. I show that Prichard holds these assumptions and then I attempt to diagnose why he holds them. In the course of this diagnosis I explore several senses of 'dependent' which (...) play a role in this view. Finally, I show that a causal dependence of secondary qualities upon the perceiver will not lead to the conclusion that secondary qualities are private unless the philosophical thesis that they are particular is already assumed.

I take up the task of examining how someone who takes seriously the ambitious programme of conceptual analysis advocated by the Canberra School can minimise the eliminative consequences which I argue the Ramsey-Carnap-Lewis recipe of conceptual analysis is likely to have for many folk discourses. The objective is to find a stable means to preserve the constative appearance of folk discourse and to find it generally successful in its attempts to describe an external world, albeit in non-scientific terms that (...) do not reflect the nature of things. The view I settle on, quasi-fictionalism, is modelled on a modified descriptivist version of Kendall Walton’s account of prop-oriented games of make-believe. (shrink)

There are propositions constituting the content of fictions—sometimes of the utmost importance to understand them—which are not explicitly presented, but must somehow be inferred. This essay deals with what these inferences tell us about the nature of fiction. I will criticize three well-known proposals in the literature: those by David Lewis, Gregory Currie, and Kendall Walton. I advocate a proposal of my own, which I will claim improves on theirs. Most important for my purposes, I will argue (...) on this basis, against Walton’s objections, for an illocutionary-act account of fiction, inspired in part by some of Lewis’s and Currie’s suggestions, but (perhaps paradoxically) above all by Walton’s deservedly influential views. (shrink)

Here, I defend the view that fictional narratives are illusionary and that fictional names are to be accounted metalinguistically, a blend of Walton’s and Donnellan’s theories. Besides, I offer a remedial semantic for sentences external to the story which connects those uses back to the text of the story and to the neighborhood of its retellings.

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.

This paper analyzes Kendall Walton's theory of depiction and, more specifically, his notion of twofoldness. I argue that (1) Walton’s notion of twofoldness is, in spite of what Walton claims, very different from Richard Wollheim’s and (2) Walton’s notion of twofoldness is inconsistent with the rest of his theory of depiction.
