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)

In this overview article, we first explain what we take informal logic to be, discussing misconceptions and distinguishing our conception of it from competing ones; second, we briefly catalogue recent informal logic research, under 14 headings; third, we suggest four broad areas of problems and questions for future research; fourth, we describe current scholarly resources for informal logic; fifth, we discuss three implications of informal logic for philosophy in particular, and take note ofpractical consequences of a more general sort.

While many "benchtop-to-bedside" research pathways have been developed in "Type I" translational medicine, vehicles to facilitate "Type II" and "Type III" translation that convert scientific data into clinical and community interventions designed to improve the health of human populations remain elusive. Further, while a high percentage of physicians endorse the principle of citizen leadership, many have difficulty practicing it. This discrepancy has been attributed, in part, to lack of training and preparation for public advocacy, time limitation, and institutional resistance. As (...) translational medicine and physician-citizenship implicate social, political, economic and cultural factors, both enterprises require "integrative" research strategies that blend insights from multiple fields of study, as well as rhetorical acumen in adapting messages to reach multiple audiences. This article considers how argumentation theory's epistemological flexibility, audience attentiveness, and heuristic qualities, combined with concepts from classical rhetoric, such as rhetorical invention, the synecdoche, and ethos, yield tools to facilitate translational medicine and enable physician-citizenship.

In this paper it is argued that much can be gained for the analysis and evaluation of arguing when fallacies are not, or not only, conceived of as flawed premise–conclusion complexes but rather as argumentative moves which distort harmfully an interaction aiming at resolving communication problems argumentatively. Starting from Normative Pragmatics and the pragma-dialectical concept of fallacy, a case study is presented to illustrate a fallacy which is termed the 'revelation argument' because it is characterized by an interactor's revealing her (...) thoughts and/or emotions to the addressees and claiming that these would have justificatory or refutatory potential with respect to the problem discussed. Although the revelation argument may not be a paradigm case of resolution- hindering moves, it is an extreme case of flawed reasoning that illustrates plainly the advantages of a communicational perspective on arguing and fallacies.

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.

How do Dutch people let each other know that they disagree? What do they say when they want to resolve their difference of opinion by way of an argumentative discussion? In what way do they convey that they are convinced by each other’s argumentation? How do they criticize each other’s argumentative moves? Which words and expressions do they use in these endeavors? By answering these questions this short essay provides a brief inventory of the language of argumentation in Dutch.

Since Toulmin’s discovery of the field-dependency of arguments, and Perelman’s emphasis on audiences, argumentation theorists have developed the notion of “spheres of arguments” or “argument communities”. Since argument communities are communities of discourse guided by the participants’ cog-nitive experiences, they are also cognitive communities. “Cognitive breaks” between different argument communities will produce misunderstanding and futile argument. The paper will investigate “cognitive breaks” and describe in which ways they may obstruct reasonable argumentation between communities.

The article outlines a general epistemological theory of argument: a theory that regards providingjustified belief as the principal aim of argumentation, and defends it instrumentalistically. After introducing some central terms of such a theory, answers to its central questions are proposed: the primary object and structure of the theory, the function of arguments, which is to lead to justified belief, the way such arguments function, which is to guide the addressee's cognizing, objective versus subjective aspects of argumentation, designing different types (...) of argument. Then the notion of ' valid argument' is defined and criteria for the adequate use of such arguments are introduced. Finally, this conception is justified as, among others, leading to more true beliefs than competing conceptions. (shrink)

I propose some changes to the conceptions of argument and of argumentative discussion in Ralph Johnson's Manifest Rationality (2000). An argument is a discourse whose author seeks to persuade an audience to accept a thesis by producing reasons in support of it and discharging his dialectical obligations. An argumentative discussion (what Johnson calls ‘argumentation’) is a sociocultural activity of constructing, presenting, interpreting, criticizing, and revising arguments for the purpose of reaching a shared rationally supported position on some issue. Johnson's theory (...) of argumentative discussion, with occasional modifications, is derived from this definition as a sequence of 17 theorems. Argumentative discussion is a valuable cultural practice; it is the most secure route to correct views and wise policies. (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)

This paper examines Andrei Sakharov's dissident protests against the Soviet regime as arguments to a non-cooperating interlocutor. Approaching the 1970s-1980s Soviet dissident public sphere as a Toulminian ‘field’ of argumentation, I infer a field-dependent function of Sakharov's argument from an analysis of its structure and implicit assessment criteria. Besides justification, the function of Sakharov’s argument is performative: he argues for political action by demonstrating a model of practical reasoning that raises private consciousness to the level of public agency. By exposing (...) his own political rationality as a ‘live’ mode of proof for the speculative ‘truth’ of his conviction, Sakharov suggests a connection between theoretical thinking and action.

From Spinoza to today, it has been noted that human beings respond to what is unusual in our lives. The advertising community knows this and struggles to find ways to be unusual in the face of an estimated 3,500 ads per day. One way is through emotion. This paper examines arguments made in advertisements where emotional cognition is appealed to and how they differ from ads that appeal to rational cognition.

This book contains 20 essays tracing the work of David Zarefsky, a leading North American scholar of argumentation from a rhetorical perspective. The essays cohere around 4 general themes: objectives for studying argumentation rhetorically, approaches to rhetorical study of argumentation, patterns and schemes of rhetorical argumentation, and case studies illustrating the potential of studying argumentation rhetorically. These articles are drawn from across Zarefsky’s 45-year career. Many of these articles originally appeared in publications that are difficult to access today, and this (...) collection brings the reader up to date on the topic. Zarefsky’s scholarship focuses on the role of language in political argumentation, the ways in which argumentation creates public knowledge and belief, the influence of framing and context on what is said and understood, the deployment of particular patterns and schemes of argumentation in public reasoning, and the influence of debate on politics and governance. All these topics are addressed in this book. Each of the conceptual essays includes brief application to specific cases, and five extended case studies are also presented in this volume. The case studies cover different themes: two explore famous political debates, the third focuses on presidential rhetoric across the course of United States history, the fourth on the arguments for liberalism at a time of political polarization, and the fifth on the contemporary effort to engage the United States with the Muslim world. This book is of interest to scholars in the fields of philosophy, logic, law, philosophy of law, and legal history. The range of topics and concepts addressed, the interplay of concepts and cases and the unifying perspective of rhetorical argumentation make this book a valuable read for students of argumentative practice, whether rhetorically or otherwise.

In The Uses of Argument, Stephen Toulmin proposed a model for the layout of arguments: claim, data, warrant, qualifier, rebuttal, backing. Since then, Toulmin’s model has been appropriated, adapted and extended by researchers in speech communications, philosophy and artificial intelligence. This book assembles the best contemporary reflection in these fields, extending or challenging Toulmin’s ideas in ways that make fresh contributions to the theory of analysing and evaluating arguments.

More than current scholarship in argumentation suggests, successful defense of standpoints depends on learning. As long as arguers comply with a minimum co-operativity, argumentation has genuinely an epistemic interest insofar as any position agreed upon becomes agreeable, i.e., intersubjectively shared because those who did not share it have learned why it is agreeable. Since the epistemic interest of argumentation is absent from most of current scholarship, `intersubjectification' is basically treated as being always possible. In this paper I argue that `intersubjectification' (...) – the `matching of the arguers' communicative backgrounds,' as I will term it – is not a given, but a communicative activity which may or may not succeed. Hence, different types of arguing come into being, depending on how and what arguers are prepared to learn. In the paper, examples are given for unproblematic `intersubjectification,' for `intersubjectification' that requires considerable argumentative co-operation, and for `intersubjectification' that fails utterly. From the analyses, a continuous scale of types of communicative processes of arguing is presented that ranges from one extreme case, termed `dogmatic arguing,' to another extreme case, termed `emergent arguing.'.

The move to Postmodernism in argumentation is often predicated on the rejection of the formal basis of argument in logic. While this rejection may be justified, and is widely discussed in the literature, the loss of logic creates problems that a Postmodern theory of argument must address without recourse to logic and its attendant modernist assumptions. This essay argues that conceiving of argument in terms ofpractices will address the key problematics of Postmodernism without abandoning those features of argumentation that make (...) it an important social, cultural and political practice. Implications for both theory and pedagogy are discussed. (shrink)

This paper is concerned with argumentation in legal proceedings, namely in criminal cases. My interest is to explore how in the legal realm different argumentation fields interact, the juridical field being just one of them. The paper lays out an approach of studying argumentation in the legal realm in the framework of an ethnographic methodology by identifying the “topical rules” the participants in criminal trials adhere to. Suggesting the notion of field-dependence as a good starting point for the analysis of (...) legal argumentation, I will give several examples of different fields of argumentation interacting in criminal proceedings. The examination of what counts as a good reason and how arguments are employed, negotiated, and evaluated within a criminal proceeding might shed light on the practice of constructing facts and arriving at decisions in court. It can furthermore point at the constitution of legal rationality and how it is produced in criminal trials. I argue that rationality in criminal proceedings is interactively accomplished by negotiating different standards of validity. (shrink)

Argumentation is a form of communication, rather than an application of(formal) logic, and is used in communicative activity as a means forinquiry, although it is more typically thought of as bringing inquiry toclosure. Thus interpretation is an intrinsic and crucial aspect ofconversational (interactive) argumentation. In order to further thisunderstanding of argumentative activity, I propose a procedure forinterpretation that draws upon hermeneutic phenomenology. In response tocriticisms by argumentation theorists (and others) who understand thistradition as oriented to psychological, perceptual, or textual objects, (...) Iargue that hermeneutic phenomenology supports methods for analysis ofpublic communicative activity. The resulting conception of ’thick argumentation‘ responds to contemporary (postmodern) claims that argumentation valorizes univocity, stasis, and certainty at the expense ofthe pluralism, fluctuation, and range of epistemic results thatcharacterize discourse in the public sphere.

The current dominant approach on the assessment of critical thinking takes as a starting point a conception of criticality that does not commit to any substantive view or context of meaning concerning what issues are relevant to be critical about in society or in life. Nevertheless, as a detailed examination of the identification of assumptions shows, when going from the theory of critical thinking to the praxis of producing and evaluating arguments, the critical person will inevitably make such commitments from (...) particular perspectives, using particular contexts of meaning. But then she may fail to take notice of relevant ones and may end up using her critical powers in a mercenary way. It is then proposed, in the context of assessment of critical thinking, to choose and use some privileged contexts of meaning, while making them available for critical scrutiny and allowing for the possibility that new ones be brought up by those being assessed.

In addition to functions traditionally ascribed to the socio-linguistic practice of arguing for a thesis, we can add: determining whether an advertisement is ethical. Ads regularly use fallacy and exaggeration, but when an ad uses argumentation that is based in unfair, damaging, dangerous fallacy, we may question its ethics. This paper uses Gilbert's model of Multi-Modal Argumentation to decide whether the arguments underlying an advertisement make it an ethical one.

This paper examines, in studies utilizing Gilbert’s Multi-Modal Argumentation Model, processing of emotional arguments in ads which, due to Western Society’s bias, has tended toward logical analysis, even though they are emotional arguments. It explores reframing the analysis in the culture of Informal Logic, with particular reference to issues of the alethic status of premises, the ethics of claims, the context of assumptions, and the question of what constitutes truth in the context of emotions.
