Neumann, Otto Kirchheimer, and Jürgen Habermas formulated innovative ideas about the transformations of state and law in the context of contemporary capitalism, ideas that remain surprisingly pertinent to contemporary trends. Not surprisingly perhaps, we can find echoes of their ideas among contemporary Frankfurt-oriented critical theorists now grappling with the myriad challenges posed by globalization to the rule of law and constitutionalism.
