Rational Interaction As The Basis For Communication

Abstract

This paper derives the basis of a theory of communication from a formal theory of rational interaction. The major result is a demonstration that illocutionary acts need neither be primitive, nor explicitly recognized. As a test case, we derive Searle’s conditions on requesting from principles of rationality coupled with a theory of imperatives. The theory rests on a formal account of intention and distinguishes insincere or nonserious imperatives from true requests. A theory of purposeful communication thus emerges as a consequence of principles of action and interaction.
