Argumentation logicians have recognized a specter of relativism to haunt their philosophy of argument. However, their attempts to dispel pernicious relativism by invoking notions of a universal audience or a community of model interlocutors have not been entirely successful. In fact, their various discussions of a universal audience invoke the context-eschewing formalism of Kant’s categorical imperative. Moreover, they embrace the Kantian method for resolving the antinomies that continually vacillates between opposing extremes – here between a transcendent universal audience and a (...) context-embedded particular audience. This tack ironically restores the very external mediation they thought to obviate in their aim to ‘dethrone’ the absolutism and totalitarianism of formal logic with a democratic turn to audience adherence, the acceptability of premises and inferential links, and a contextual, or participant-relative, notion of cogency.

This discussion reviews the thinking of some prominent philosophers of argument to extract principles common to their thinking. It shows that a growing concern with dialogical pragmatics is better appreciated as a part of applied ethics than of applied epistemology. The discussion concludes by indicating a possible consequence for philosophy of argument and invites further discussion by asking whether argumentation philosophy has an implicit, underlying moral, or even political, posture.

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)

In a posthumous paper, Perelman discusses his decision to bring his theory of argumentation together with rhetoric rather than calling it an informal logic. This is due in part because of the centrality he gives to audience, and in part because of the negative attitude that informal logicians have to rhetoric. In this paper, I explore both of these concerns by way of considering what benefits Perelman’s work can have for informal logic, and what insights the work of informal logicians (...) might bring to the project of Perelman and Olbrechts-Tyteca.

In this paper, I propose that the inquiry known as a/the theory of argument is the “invention” of Trudy Govier, using that term in its rhetorical sense, viz., the process of choosing ideas appropriate to the subject. In her paper, “Is a Theory of Argument Possible?” Govier used the idea of theory of argument to focus her discussion on problems in argument analysis and evaluation that came to light in the 1970s and 1980s. The idea of a theory of argument (...) was already there but Govier “discovered” it in the sense that she made its potential clear. (shrink)

Informal logic is a new sub-discipline of philosophy, roughly definable as the philosophy of argument. Contributors have challenged the traditional concept of an argument as a premiss-conclusion complex, in favour of speech-act, functional and dialogical conceptions; they have identified as additional components warrants, modal qualifiers, rebuttals, and a dialectical tier. They have objected that "soundness" is neither necessary nor sufficient for a good argument. Alternative proposals include acceptability, relevance and sufficiency of the premisses; conformity to a valid argument schema; conformity (...) to rules for discussion aimed at rational resolution of a dispute. Informal logic is a significant part of philosophy. (shrink)

I wish to argue in favor of a particular orientation, one expressed in Brockriede’s remark that “aruments are not in statements but in people.” While much has been gained from textual analyses, even more will accrue by additional attention to the arguers. I consider that textual materials are really only the artifacts of arguments. The actual arguing is done exclusively by people, either the argument producers or receivers, and never by words on a page. In fact, most of our textua (...) l interpretations are quietly founded on the assumption that the artifact is fully informative about what people think. (shrink)

We argue that Hilary Putnam's pragmatism provides an epistemological perspective which can help us understand--and can positively inform--the development of informal logic.

Given the pragmatic tum recently taken by argumentation studies, we owe renewed attention to Henry Johnstone's views on the primacy of process over product. In particular, Johnstone's decidedly non-cooperative model is a refreshing alternative to the current dialogic theories of arguing, one which opens the way for specifically rhetorical lines of inquiry.

I begin by formulating the problem of the nature of fallacy in terms of the logic of the negative evaluation of argument, that is, in terms of a theory of logical criticism; here I discuss several features of my approach and several advantages vis-à-vis other approaches; a main feature of my approach is the concern to avoid both formalist and empiricist excesses. I then define six types of fallaciousness, labeled formal, explanatory, presuppositional, positive, semantical, and persuasive; they all involve arguments (...) whose conclusion may be said not to follow from the premises, that is, they involve the logical evaluation of relationships among propositions. I also provide a set of data consisting of four historical cases or nine specific instances of fallacious arguments; these all pertain to the Copernican controversy about the earth's motion in the seventeenth century. I end with a discussion of further problems and inquiries that deserve attention. (shrink)

This essay begins with a brief description of my approach to the study of argumentation and fallacies which is empirical, historical-textual, dialectical, and meta-argumentational. It then focuses on the fallacy of composition and elaborates a number of conceptual definitions and distinctions: argument of composition; fallacy of composition; arguments and fallacies of division; arguments that confuse the distributive and collective meaning of terms; arguments from a property belonging to members of a group to its belonging to the entire group; several nuanced (...) schemes for arguments of composition; and several principles for the evaluation of such arguments. I then call attention to the fact that some scholars have claimed that the basic argument for global warming commits the fallacy of composition, and undertake a critical analysis of this claim. I show that the global-warming argument is not a fallacy of composition, but is rather a deductively valid argument of composition from the temperature of the parts to the temperature of the whole earth; moreover, I criticize the meta-argumentation of these scholars by showing that the global-warming argument is not similar to the one for global pollution, which is indeed fallacious; finally, I argue that these scholars confuse the global-warming argument with the argument claiming that all effects of global warming are harmful, which is indeed incorrect as a hasty generalization.

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 paper will describe what happened to the community of informal logicians between 1983 and 1987, when they started to interact with communication scholars, rhetoricians and Pragma-Dialecticians. Special attention will be paid to key events, such as the Second International Symposiums on Informal Logic, the founding of AILACT in 1983, the start of journal Informal logic in 1984, and the international conference on argumentation held at Amsterdam in 1986.

This paper examines whether philosophers of argument, in spite of their disavowing ‘timeless principles’, nevertheless embrace a set of principles, or axioms, to underlie argumentation theory. First, it reviews the thinking of some prominent philosophers of argument; second, it extracts some principles common to their philosophies; and third, it draws out possible consequences for argumentation theory and asks whether such theory has an underlying political posture.

When ‘making a case’ in court, the defense lawyer engages different arguments in a situated performance. At the same time, these arguments have developed over time in front of different audiences. In this paper I will follow the construction of arguments in an actual criminal case from preparation to the trial by focusing on the developments and refinements of the arguments that inform and shape the case.
