Preuss' paper significantly advances the critical theory of law. As a side benefit, he provides English-speakers with an excellent introduction to the work of two leading West German participants in the debate, Jürgen Habermas and Gunther Teubner. Preuss' paper reveals considerable common ground between critical legal theorists in Germany and the United States, but also important differences of perspective and concern. I suspect that many American legal critics will think that Preuss' criticisms of Habermas and Teubner do not go far enough, that his criticisms raise a fundamental challenge to the current emphasis on structure and system in the German debate. In any event, Preuss' paper suggests the usefulness of a greater German “reception” of the American emphasis on agency and social construction. No doubt American legal criticism would likewise be enriched by entering into a more sustained dialogue with structuralist and systems theory.
