The book offers a compact but comprehensive introductory overview of the crucial components of argumentation theory. In presenting this overview, argumentation is consistently approached from a pragma-dialectical perspective by viewing it pragmatically as a goal-directed communicative activity and dialectically as part of a regulated critical exchange aimed at resolving a difference of opinion. As a result, the book also systematically explains how the constitutive parts of the pragma-dialectical theory of argumentation, which are discussed in a number of separate publications, hang together.The following crucial topics are discussed: (1) argumentation theory as a discipline, (2) the meta-theoretical principles of pragma-dialectics, (3) the model of a critical discussion aimed at resolving a difference of opinion, (4) fallacies as violations of a code of conduct for reasonable argumentative discourse, (5) descriptive research of argumentative reality, (6) analysis as theoretically-motivated reconstruction, (7) strategic manoeuvring aimed at combining achieving effectiveness with maintaining reasonableness, (8) the conventionalization of argumentative practices, (9) prototypical argumentative patterns, (10) pragma-dialectics amidst other approaches.Argumentation Theory: A Pragma-Dialectical Perspective is clearly written and makes argumentation theory understandable to all scholars and advanced students interested in argumentation research.
