The informal logic movement began as an attempt to develop – and teach – an alternative logic which can account for the real life arguing that surrounds us in our daily lives – in newspapers and the popular media, political and social commentary, advertising, and interpersonal exchange. The movement was rooted in research and discussion in Canada and especially at the University of Windsor, and has become a branch of argumentation theory which intersects with related traditions and approaches (notably formal (...) logic, rhetoric and dialectics in the form of pragma-dialectics). In this volume, some of the best known contributors to the movement discuss their views and the reasoning and argument which is informal logic’s subject matter. Many themes and issues are explored in a way that will fuel the continued evolution of the field. Federico Puppo adds an insightful essay which considers the origins and development of informal logic and whether informal logicians are properly described as a “school” of thought. In considering that proposition, Puppo introduces readers to a diverse range of essays, some of them previously published, others written specifically for this volume. (shrink)

Topical Themes in Argumentation Theory brings together twenty exploratory studies on important subjects of research in contemporary argumentation theory. The essays are based on papers that were presented at the 7th Conference of the International Society for the Study of Argumentation in Amsterdam in June 2010. They give an impression of the nature and the variety of the kind of research that has recently been carried out in the study of argumentation. The volume starts with three essays that provide stimulating (...) theoretical perspectives on argumentation. Subsequently, some views are explained on the intriguing topics of ‘dissensus’ and ‘deep disagreement’. After a discussion of three different approaches to the treatment of types of argumentation some classical themes from antique argumentation theory are revisited. The new research area of visual argumentation is explored in the next part. The volume concludes with three reports of experimental studies concerning argumentative discourse.

The article develops and justifies, on the basis of the epistemological argumentation theory, two central pieces of the theory of evaluative argumentation interpretation: 1. criteria for recognizing argument types and 2. rules for adding reasons to create ideal arguments. Ad 1: The criteria for identifying argument types are a selection of essential elements from the definitions of the respective argument types. Ad 2: After presenting the general principles for adding reasons (benevolence, authenticity, immanence, optimization), heuristics are proposed for finding missing (...) reasons, for deductive arguments, e.g., semantic tableaux are suggested.

This article challenges the view that rhetoric, dialectic and logic are three perspectives on argument, relating respectively to its process, its procedure, and its product. It also questions the view that rhetorical arguments represent a distinctive type. It suggests that, as related to argument, rhetoric is the theory of arguments in speeches, dialectics the theory of arguments in conversations, and logic the theory of good reasoning in each.

In this paper, I respond to papers on my Manifest Rationality (2000) by Leo Groarke, Hans Hansen, David Hitchcock, and Christopher Tindale presented at the meetings of the Ontario Philosophical Society, October 2000. From the many useful challenges they have directed at my position, I have chosen to focus on two. The dominant issue raised by their papers concerns my definition of argument, and particularly problems with the idea of a dialectical tier. I have selected that as the first strand. (...) Second, several have raised questions that deal with the relationship between logic, rhetoric and dialectic. That is the second strand. (shrink)

J. Anthony Blair is a prominent international figure in argumentation studies. He is among the originators of informal logic, an author of textbooks on the informal logic approach to argument analysis and evaluation and on critical thinking, and a founder and editor of the journal Informal Logic. Blair is widely recognized among the leaders in the field for contributing formative ideas to the argumentation literature of the last few decades. This selection of key works provides insights into the history of (...) the field of argumentation theory and various related disciplines. It illuminates the central debates and presents core ideas in four main areas: Critical Thinking, Informal Logic, Argument Theory and Logic, Dialectic and Rhetoric. (shrink)

Taking Blair’s recent contribution to the debate about the triad as its starting point, the article discusses and challenges attempts to reduce the intricate relationship between rhetoric, dialectic and logic to a trichotomy with watertight compartments or to separate them with a single clear-cut criterion. I argue that efforts to pinpoint an essential difference, among the various typical differences partly grounded in disciplinary traditions, obscure the complexities within the fields. As a consequence, crosscutting properties of the fields as well as (...) the possibilities for theoretical bridging between them are neglected. (shrink)

In this paper we describe the approach to critical thinking pedagogy used in our new text, Reason in the Balance: An Inquiry Approach to Critical Thinking. In this text we concentrate on develop-ing students’ ability to analyze and assess competing arguments in a dialectical context. This approach shifts the emphasis from the more common and traditional approach of evaluating individual arguments and fallacy identification. Our focus is on teaching students to analyze and assess competing arguments sur-rounding an issue with the (...) goal of achieving a reasoned and justifiable judgment. (shrink)

I inquire into argument at the system level, exploring the controversy over whether climate scientists should fly. I document participants’ knowledge of a skeptical argument that because scientists fly, they cannot testify credibly about the climate emergency. I show how this argument has been managed by pro-climate action arguers, and how some climate scientists have developed parallel reasoning, articulating a sophisticated case why they will be more effective in the controversy if they fly less. Finally, I review some strategies arguers (...) deploy to use the arguments of others against them. I argue that only by attending to argument-making at the system level can we understand how arguers come to know the resources for argument available in a controversy and to think strategically about how to use them. I call for more work on argument at the system level. (shrink)

This essay addresses the collapse/incoherence problem for normative frameworks that contain both fundamental values and rules for promoting those values. The problem is that in some cases, we would bring about more of the fundamental value by violating the framework’s rules than by following them. In such cases, if the framework requires us to follow the rules anyway, then it appears to be incoherent; but if it allows us to make exceptions to the rules, then the framework “collapses” into one (...) that doesn’t make use of rules in the first place. The chapter begins with an examination of happiness and truth as fundamental values in Mill’s work, which lead into parallel versions of the collapse/incoherence problem in ethics and epistemology. It then sets out the collapse problem for rule-consequentialist approaches in ethics, truth-directed accounts of justification in epistemology, and epistemological approaches to argument cogency. The chapter closes with discussion of two potential solutions to the problem. (shrink)

In a critical discussion, interlocutors can strategically maneuver by shading their expressed degree of standpoint commitment for rhetorical effect. When is such strategic shading reasonable, and when does it cross the line and risk fallacious derailment of the discussion? Analysis of President George W. Bush’s 2002–2003 prewar commentary on Iraq provides an occasion to explore this question and revisit Douglas Ehninger’s distinction between argumentation as coercive correction and argumentation as a person-risking enterprise. Points of overlap between Ehninger’s account and pragma-dialectical (...) argumentation theory suggest avenues for harmonization of rhetorical and dialectical perspectives on argumentation. Out of this conceptual convergence comes theoretical resources for understanding strategic maneuvering, by accounting for ways that discussants exploit gaps between their externalized and actual discussion attitude. As such higher-order strategic maneuvering played a major role in the 2003 Iraq prewar discourse failure, perspicacious understanding of this particular argumentative maneuver carries practical, as well as theoretical import.

This paper describes the development of pragma-dialectics as a theory of argumentative discourse. First the development of the pragma-dialectical model of a critical discussion is explained, with the rules that are to be complied with in order to avoid fallacies from occurring. Then the integration is discussed of rhetorical insight in the dialectical framework. In this endeavour, the concept of strategic manoeuvring is explained that allows for a more refined and more profoundly justified analysis of argumentative discourse and a better (...) identification of fallacies. The paper ends with a brief overview of current research projects. (shrink)

A critical examination of the dialectical approach, focusing on a comparison ofthe illative and the dialectical definitions of argument. I distinguish a moderate, a strong and a hyper dialectical conception of argument. I critique Goldman's argument for the moderate conception and Johnson's argument for the strong conception, and argue that the moderate conception is correct.

The first part of this essay argues that the specification of rationality operating in Manifest Rationality does not allow for the inclusion of the dialectical tier as a necessary component of a rational product. It next considers Perelman's conception of "reasonableness" as an alternative to Johnson's structural sense of rationality. Adopting a contextually rich conception of rationality, like that of Perelman, allows Johnson to insist that a rational product must consist of both an illative core and a dialectical tier.

‘In Context’ is aimed at giving contextualization its rightful place in the study of argumentation. First, Frans H. van Eemeren explains the crucial role of context in a reconstructive analysis of argumentative discourse. He distinguishes four levels of contextualization. Second, he situates his approach to context in the field of argumentation studies by comparing it with Walton’s approach. He emphasizes the importance of distinguishing clearly between a normatively motivated theoretical ideal model and empirically-based communicative activity types. Third, van Eemeren concentrates (...) on the ‘macro-level’ of contextualization: contextualization in institutionalized communicative activity types. He makes clear that the macro-context of a communicative activity type can be characterized argumentatively by describing the disctinctive features of the empirical counterparts of the four stages of a critical discussion in the activity type concerned. Fourth, he points out what the consequences of the macrocontextualization of argumentative discourse in a certain communicative activity type are for the strategic maneuvering that may takes place and the identification of fallacies as derailments of strategic maneuvering. Fifth, van Eemeren draws some general conclusions regarding the role of contextualization in the analysis and evaluation of argumentative discourse. (shrink)

This paper has three dimensions, historical, theoretical and social. The historical dimension is to show how the Ciceronian system of dialectical argumentation served as a precursor to computational models of argumentation schemes such as Araucaria and Carneades. The theoretical dimension is to show concretely how these argumentation schemes reveal the interdependency of rhetoric and logic, and so the interdependency of the normative with the empirical. It does this by identifying points of disagreement in a dialectical format through using argumentation schemes (...) and critical questions. The social dimension is to show how the Ciceronian dialectical viewpoint integrates with the use of computational tools that can be used to support the principle of reason-based deliberation and facilitate deliberative democracy.

Taking Blair’s recent contribution to the debate about the triad as its starting point, the paper discusses and challenges the effort to reduce the intricate relationship between rhetoric, dialectic, and logic to a single criterion or watertight trichotomy. I argue that such efforts obscure the complexities within the fields, their differences being partly due to disciplinary traditions. They neglect the intermingling properties of the fields as well as the possibilities for theoretical bridging between them.
