The coordination and integration of social action has been explained in many ways by many theories. Rational choice theory and game theory are two examples, which describe the integration of individuals into social groups by detailing the complex manner in which individuals motivated only by self-interest will form mutually beneficial and cooperative social arrangements. In contrast to these, Habermas has formulated a theory of "communicative action". (Habermas 1984; 1987) This theory and the project of developing a formal pragmatic analysis of communication are inseparable.
