Develops a logical analysis of dialogue in which two or more parties attempt to advance their own interests. It includes a classification of the major types of dialogues and a discussion of several important informal fallacies.

This paper presents an analysis of the concept of burden of proof in argument. Relationship of burden of proof to three traditional informal fallacies is considered: (i) argumentum ad hominem, (ii) petitio principii, and (iii) argumentum ad ignorantiam. Other topics discussed include persuasive dialoque, pragmatic reasoning, legal burden of proof, plausible reasoning in regulated disputes, rules of dialogue, and the value of reasoned dialogue.

The paper presents a historical overview of some characteristic differences between rhetoric and dialectic in the pre-modern tradition. In the light of this historical analysis, some current approaches to dialectic are characterized, with special attention to Ralph Johnson's concept of dialectical tier.

He further argues that it is necessary to rethink traditional conceptions of argument, and to find a position that avoids the limitations of both the highly abstract approach of formal logic and the highly contextualized approaches of rhetoric and communication theory.".

This volume contains 12 papers addressed to researchers and advanced students in informal logic and related fields, such as argumentation, formal logic, and communications. Among the issues discussed are attempts to rethink the nature of argument and of inference, the role of dialectical context, and the standards for evaluating inferences, and to shed light on the interfaces between informal logic and argumentation theory, rhetoric, formal logic and cognitive psychology.

The paper reacts against the strict separation between dialectical and rhetorical approaches to argumentation and argues that argumentative discourse can be analyzed and evaluated more adequately if the two are systematically combined. Such an integrated approach makes it possible to show how the opportunities available in each of the dialectical stages of a critical discussion have been used strategically to further the rhetorical aims of the speaker or writer. The approach is illustrated with the help of an analysis of an (...) `advertorial' published by R. J. Reynolds Tobacco Company. (shrink)

Normative pragmatics can bridge the differences between dialectical and rhetorical theories in a way that saves the central insights of both. Normative pragmatics calls attention to how the manifest strategic design of a message produces interpretive effects and interactional consequences. Argumentative analysis of messages should begin with the manifest persuasive rationale they communicate. But not all persuasive inducements should be treated as arguments. Arguments express with a special pragmatic force propositions where those propositions stand in particular inferential relations to one (...) another. Normative pragmatics provides a framework within which varieties of propositional inference and pragmatic force may be kept straight. Normative pragmatics conceptualizes argumentative effectiveness in a way that integrates notions of rhetorical strategy and rhetorical situation with dialectical norms and procedures for reasonable deliberation. Strategic effectiveness should be seen in terms of maximizing the chances that claims and arguments will be reasonably evaluated, whether or not they are accepted. Procedural rationality should be seen in terms of adjustment to the demands of concrete circumstances. Two types of adjustment are illustrated: rhetorical strategies for framing the conditions for dialectical deliberation and rhetorical strategies for making do with limitations to dialectical deliberation.

tational background of dialectic: the structure of formal disputation. Formal disputation Perhaps the clearest, and surely historically the most prominent, ...

In this paper I explore Ralph Johnson's proposal that in addition to premises and conclusion every argument should have a dialectical tier in which the arguer addresses objections to the argument, and considers alternative positions. After exploring several reasons for thinking that Johnson's proposal is a good one, I then raise a number of objections against it and move ahead to respond to those objections, which I do by distinguishing making out a case for a conclusion from offering an argument (...) for it, and distinguishing supplementary arguments from one's main argument. I contend that it is not realistic to see arguers as having an obligation to respond to all objections and to address all alternative positions; we must somehow discriminate those which need and merit a reply from those which do not.

In her 1997 OSSA paper, Trudy Govier discusses in detail my thesis that arguers have dialectical obligations. In a 1998 paper she further examines this thesis to see whether it is viable and concludes that it faces serious problems. In this paper, I assess the state of the thesis in light of Govier's discussion of it. I urge that we have something to gain from the empirical turn--from investigating best practices. At the end, I take a step back to ask (...) what is really at issue here and how it connect s to other issues in the theory of argument. (shrink)
