Though many legal theorists are familiar with Jürgen Habermas's work addressing core legal concerns, they are not necessarily familiar with his earlier writings in philosophy and social theory. Because Habermas's later work on law invokes, without significant explanation, the whole battery of concepts developed in earlier phases of his career, even otherwise sympathetically inclined legal theorists face significant obstacles in evaluating his insights. A similar difficulty faces those outside the legal academy who are familiar with Habermas's earlier work. While they readily comprehend Habermas's basic social-theoretical concepts, without special legal training they have difficulty reliably assessing his recent engagement with contemporary legal thought. This new work bridges the gap between legal experts and those without special legal training, critically assessing the attempt of an unquestionably preeminent philosopher and social theorist to engage the world of law.
