Abstract

A goal-oriented analysis of argument is presented based on Taylor's layered protocols, a theory of communication based on Powers' hierarchical perceptual control theory. Goals and beliefs are hierarchical, related in a precise way to sensory inputs an d motor outputs. This model is combined with Gilbert's theory of coalescent argumentation. Participants sketch out their own and their partner's goal diagrams as an aid to resolving the argument. For this to work, the argument must be viewed, not in pu rely linguistic or logical terms, but in terms of the entire system of goals in which it is embedded.
