Plausible (eikotic) reasoning known from ancient Greek (late Academic) skeptical philosophy is shown to be a clear notion that can be analyzed by argumentation methods, and that is important for argumentation studies. It is shown how there is a continuous thread running from the Sophists to the skeptical philosopher Carneades, through remarks of Locke and Bentham on the subject, to recent research in artificial intelligence. Eleven characteristics of plausible reasoning are specified by analyzing key examples of it recognized as important (...) in ancient Greek skeptical philosophy using an artificial intelligence model called the Carneades Argumentation System (CAS). By applying CAS to ancient examples it is shown how plausible reasoning is especially useful for gaining a better understanding of evidential reasoning in law, and argued that it can also be applied to everyday argumentation. Our analysis of the snake and rope example of Carneades is also used to point out some ways CAS needs to be extended if it is to more fully model the views of this ancient philosopher on argumentation.

This highly topical text considers the construction of the next generation of the Web, called the Semantic Web. This will enable computers to automatically consume Web-based information, overcoming the human-centric focus of the Web as it stands at present, and expediting the construction of a whole new class of knowledge-based applications that will intelligently utilise Web content. -/- The text is structured into three main sections on knowledge representation techniques, reasoning with multi-agent systems, and knowledge services. For each of these (...) topics, the text provides an overview of the state-of-the-art techniques and the popular standards that have been defined. Numerous small programming examples are given, which demonstrate how the benefits of the Semantic Web technologies can be realised at the present time. The main theoretical results underlying each of the technologies are presented, and the main problems and research issues which remain are summarised. -/- Based on a course on 'Multi-Agent Systems and the Semantic Web' taught at the University of Edinburgh, this text is ideal for final-year undergraduate and graduate students in Mathematics, Computer Science, Artificial Intelligence, and Logic and researchers interested in Multi-Agent Systems and the Semantic Web.

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.

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.

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.

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.

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)
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)
This article questions social constructionists' claims to introduce Wittgenstein's philosophy to psychology. 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. It is argued that a neonate Crusoe's viability in philosophy and apparent absence in psychology offends against the integrity of the philosophical contribution Wittgenstein might make to psychology. The consequences of accepting Crusoe's viability are explored as they (...) appear in both philosophy and psychology. (shrink)
The aim of the paper is to advance the theory of argument or inference schemes by suggesting answers to questions raised by Walton's Argumentation Schemes for Presumptive Reasoning (1996), specifically on: the relation between argument and reasoning; distinguishing deductive from presumptive schemes, the origin of schemes and the probative force of their use; and the motivation and justification for their associated critical questions.
The untimely passing of Reverend Canon Dr Christopher Newell, AM, came as a shock to many in the bioethics world. As well as an obituary, this article notes a number of important themes in his work, and provides a select bibliography. Christopher's major contribution to this field is that he was one of a handful of scholars who made disability not only an acceptable area of bioethics—indeed a vital, central, fertile area of enquiry. Crucially Christopher emphasised (...) that where we do ethics is actually in everyday life—while we mourn his passing, his rich work and example will continue to inspire bioethical inquiry. (shrink)

The notions of types of dialogue and dialectical relevance are central themes in Walton’s work and the grounds for a dialectical approach to many fallacies. After outlining the dialogue models constituting the background of Walton’s account, this article presents the concepts of dialectical relevance and dialogue shifts in their application to biased argumentation, fallacious moves, and illicit argumentative strategies. Showing the different dialectical proposals Walton advanced in several studies on argumentation as a development of a dialogical system, (...) it has proved possible to highlight the fundamental aspects of his theory in a comprehensive model of communication and interaction.

This paper is about Christopher Wren’s engravings for Thomas Willis’ The Anatomy of the Brain and Nerves of 1664. It is a study in the intersection of medicine and art in 17th century Britain. Willis, an eminent English physician and anatomist, was a major figure in the development of modern neurology, and The Anatomy of the Brain and Nerves was his most famous and influential book. Wren was Willis’ assistant and medical artist. I discuss the visual strategies employed by (...) Wren to present their research and frame it as genuine knowledge. (shrink)
David Hume's relatively short essay 'Of the Standard of Taste' deals with some of the most difficult issues in aesthetic theory. Apart from giving a few pregnant remarks, near the end of his discussion, on the role of morality in aesthetic evaluation, Hume tries to reconcile the idea that tastes are subjective (in the sense of not being answerable to the facts) with the idea that some objects of taste are better than others. 'Tastes', in this context, are the pleasures (...) or displeasures that a person can take in the beauties of poems, paintings, and other artistic compositions (though Hume also wants to stress the continuities between tastes, so understood, and the bodily sense of taste). The position at which Hume arrives in the essay (despite some dialectical unclarity) is that some people – the 'true judges'– determine by their 'joint verdict' which works are meritorious. This solution continues to exercise a fascination, as does Hume's complicated route to it. Author Recommends: Paul Guyer, 'The Standard of Taste and the "Most Ardent Desire of Society" ', Values of Beauty (Cambridge: Cambridge University Press, 2005), 37–76.

This chapter, embedded in an exposition of Mothersill's 'First Thesis' (the denial that there are principles of taste) and 'Second Thesis' (the affirmation that some judgments of taste are genuine judgments), gives a detailed running commentary on Hume's essay.

In this interview, Christopher Norris discusses a wide range of issues having to do with postmodernism, deconstruction and other controversial topics of debate within present-day philosophy and critical theory. More specifically he challenges the view of deconstruction as just another offshoot of the broader postmodernist trend in cultural studies and the social sciences. Norris puts the case for deconstruction as continuing the 'unfinished project of modernity' and—in particular—for Derrida's work as sustaining the values of enlightened critical reason in various (...) spheres of thought from epistemology to ethics, sociology and politics. Along the way he addresses a number of questions that have lately been raised with particular urgency for teachers and educationalists, among them the revival of creationist doctrine and the idea of scientific knowledge as a social, cultural, or discursive construct. In this context he addresses the 'science wars' or the debate between those who uphold t. (shrink)
The paper examines Walton‘s concept of fallacy as it develops throughthree stages of his work: from the early series of papers co-authored withJohn Woods; through a second phase of involvement with thepragma-dialectical perspective; and on to the final phase in which heoffers a distinct pragmatic theory that reaches beyond the perceived limitsof the pragma-dialectical account while still exhibiting a debt to thatperspective and the early investigations with Woods. It is observed how Walton‘s model of fallacy is established in (...) distinction to its competitors,and its various problems and successes are discussed. (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.

In this review of Christopher Winch's new book, Education, Autonomy and Critical Thinking (2006), I discuss its main theses, supporting some and criticising others. In particular, I take issue with several of Winch's claims and arguments concerning critical thinking and rationality, and deplore his reliance on what I suggest are problematic strains of the later Wittgenstein. But these criticisms are not such as to upend Winch's powerful critique of antiperfectionism and 'strong autonomy' or his defence of 'weak autonomy'. His (...) account of autonomy as an educational aim is important and in several respects compelling. (shrink)
Responding to criticisms raised by Christopher Norris, this paper defends an anti-relativist reading of the work of both Davidson and Heidegger arguing that that there are important lessons to be learnt from their example - one can thus be an anti-relativist (as well as a certain sort of realist) without giving up on Davidson or on Heidegger.
In this book, Christopher Peacocke proposes a general theory about what it is for a thinker to be entitled to form a given belief. This theory is distinctively rationalist: that is, it gives a large role to the a priori, while insisting that the propositions or contents that can be known a priori are not in any way “true in virtue of meaning” (and without in any other way denigrating these propositions as “trivial”, or as propositions that “tell us (...) nothing about the world”, or the like). Peacocke then applies this theory to several classical problems in epistemology — to the problem of how our sensory experiences can entitle us to form beliefs about the external world, to the problem of induction, and to the problem of what entitles us to form moral beliefs.

Christopher Bennett has argued that state support of conjugal relationships can be founded on the unique contribution such relationships make to the autonomy of their participants by providing them with various forms of recognition and support unavailable elsewhere. I argue that, in part because a long history of interaction between two people who need each other’s validation tends to produce less meaningful responses over time, long-term conjugal relationships are unlikely to provide autonomy-enhancing support to their participants. To the extent (...) that intimate relationships can provide a unique form of reciprocal support, Bennett fails to show that couples have an advantage over multiple-partner arrangements in doing so.

This paper analyzes Kendall Walton's theory of depiction and, more specifically, his notion of twofoldness.

In his contribution, “Critical Investments: AIDS, Christopher Reeve, and Queer/Disability Studies,” Robert McRuer calls for the recognition of the points of convergence between AIDS theory, queer theory, and disability theory. McRuer points out ways in which minority identity groups such as people with AIDS, gays, lesbians, and bisexuals, and those with so-called disabilities, whose status has been described by others as “impaired,” have resisted this judgment by calling its ideological underpinnings into question. He contends that a critical alliance between (...)

In his recent book, Aquinas and the Ship of Theseus, Christopher Brown has argued that the metaphysics of St. Thomas is preferable to contemporary analyticviews because it can solve the “problem of material constitution” (PMC) without requiring us to relinquish any of the common-sense beliefs that generate that problem. In this critical study, I show that in the case of both substances and aggregates, Brown’s Aquinas endorses views that are extremely implausible. Consequently, even if it is granted that the (...) solutions to the PMC fall right out of his views, it is still not clear that this gives us reason to prefer his ontology to its competitors. I also consider Brown’s take on the status of the human being after death. (shrink)
