How to identify an argument type? On the hermeneutics of persuasive discourse
Jean H. M. Wagemans
Abstract
This paper proposes a theory of interpreting argument types as an integral part of a systematic and comprehensive ‘hermeneutics of persuasive discourse’. It first explains how such a hermeneutics can be developed based on pragmatic insights about the use of language for persuasive purposes expressed in the philosophy of argument. Then, after having provided an overview of the main hermeneutical stages involved in interpreting persuasive discourse, the paper focuses on the stage of argument type identification. It formulates a ‘hermeneutics of argument type’ in terms of the Periodic Table of Arguments (PTA), an argument categorization framework systematizing existing accounts of arguments in the broad sense of the term (topoi, loci, argument schemes, fallacies, means of persuasion). For each of the three parameters within this framework, ‘argument form’, ‘argument substance’, and ‘argument lever’, the paper describes how to determine their value by analyzing several examples of natural arguments.
