In this book Joseph Heath brings Jürgen Habermas's theory of communicative actioninto dialogue with the most sophisticated articulation of the instrumental conception of practicalrationality-modern rational choice theory. Heath begins with an overview of Habermas's action theoryand his critique of decision and game theory. He then offers an alternative to Habermas's use ofspeech act theory to explain social order and outlines a multidimensional theory of rational actionthat includes norm-governed action as a specific type.In the second part of the book Heath discussesthe more philosophical dimension of Habermas's conception of practical rationality. He criticizesHabermas's attempt to introduce a universalization principle governing moral discourse, as well ashis criteria for distinguishing between moral and ethical problems. Heath offers an alternativeaccount of the level of convergence exhibited by moral argumentation, drawing on game-theoreticmodels to specify the burden of proof that the theory of communicative action and discourse mustassume.
