This paper attempts to systematically characterize critical reactions in argumentative discourse, such as objections, critical questions, rebuttals, refutations, counterarguments, and fallacy charges, in order to contribute to the dialogical approach to argumentation. We shall make use of four parameters to characterize distinct types of critical reaction. First, a critical reaction has a focus, for example on the standpoint, or on another part of an argument. Second, critical reactions appeal to some kind of norm, argumentative or other. Third, they each have (...) a particular illocutionary force, which may include that of giving strategic advice to the other. Fourth, a critical reaction occurs at a particular level of dialogue (the ground level or some meta-level). The concepts here developed shall be applied to discussions of critical reactions by Aristotle and by some contemporary authors. (shrink)

The problem of defining ‘critical thinking’ needs a fresh approach. When one takes into consideration the sheer quantity of definitions and their obvious differences, an onlooker might be tempted to conclude that there is no inherent meaning to the term: that each author seems to consider that he or she is free to offer a definition that suits them. And, with a few exceptions, there has not been much discussion among proposers about the strength and weaknesses of the attempted definitions. (...) Therefore, the approach we will argue for here is a ‘meta-level approach’: proposers of new definitions of ‘critical thinking’ should begin by arguing that none of the current crop of definitions is viable. They should then state what kind of definition they will offer; then provide the definition and show that it satisfies the criteria stated. Our position is that new definitions should follow this meta-level approach, in addition to avoiding some common pitfalls. (shrink)

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 paper considers how the terms ‘objection,’ ‘rebuttal,’ ‘attack,’ ‘refutation,’ ‘rebutting defeater’ and ‘undercutting defeater’ are used in writings on argumentation and artificial intelligence. The central focus is on the term ‘rebuttal.’ A provisional classification system is proposed that provides a normative structure within which the terms can be clarified, distinguished from each other, and more precisely defined.
