Book excerpt: By focusing the various difficulties encountered in applying theory to practical concerns, this book explores the reasons for the absence of a radical politics in Habermas's work. In doing so, it shows that certain political implications of the theory remain unexplored. The book articulates a unique application of Habermasian theory, the actual functioning of decision-making groups, the nature of deliberative interaction, and the kinds of judgments participants must make if they are to preserve their democratic process.
