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.

The main stream of formal and informal logic as well as more recent work in discourse analysis provides a way of understanding certain arguments that particularly lend themselves to rational analysis. I argue, however, that these, and allied modes of analysis, be seen as heuristic models and not as the only proper mode of argument. This article introduces three other modes of argumen tation that emphasize distinct aspects of human communication, but that, at the same time, must be considered for (...) the full understanding of argumentation. These modes are (1) the emotional, which relates to the realm of feelings, (2) the visceral, which stems from the area of the physical, and (3) the kisceral, which covers the intuitive and non-sensory arenas. At its most extreme the view holds that arguments may be given (almost) wholly within one mode and not be at all susceptible to those methods of argument analysis previously used. A more cautious statement allows that any interactive argument will (possibly) contain elements from various modes, and that to attempt to reduce these all to the rational is prejudiced reductionism.

The thesis that propositions of law are intrinsically arguable is opposed by the antithesis that the Rule of Law is valued for the sake of legal certainty. The synthesis considers the insights of theories of rhetoric and proceduralist theories of practical reason, then locates the problem of indeterminacy of law in the context of the challengeable character of governmental action under free governments. This is not incompatible with, but required by the Rule of Law, which is misstated as securing legal (...) certainty. Defeasible certainty is the most that is desirable or achievable. (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.".

The Handbook of the Logic of Argument and Inference is an authoritative reference work in a single volume, designed for the attention of senior undergraduates, graduate students and researchers in all the leading research areas concerned with the logic of practical argument and inference. After an introductory chapter, the role of standard logics is surveyed in two chapters. These chapters can serve as a mini-course for interested readers, in deductive and inductive logic, or as a refresher. Then follow two chapters (...) of criticism; one the internal critique and the other the empirical critique. The first deals with objections to standard logics (as theories of argument and inference) arising from the research programme in philosophical logic. The second canvasses criticisms arising from work in cognitive and experimental psychology. The next five chapters deal with developments in dialogue logic, interrogative logic, informal logic, probability logic and artificial intelligence. The last chapter surveys formal approaches to practical reasoning and anticipates possible future developments. Taken as a whole the Handbook is a single-volume indication of the present state of the logic of argument and inference at its conceptual and theoretical best. Future editions will periodically incorporate significant new developments. (shrink)
