This is Jurgen Habermas's most concrete historical-sociological book and one of the key contributions to political thought in the postwar period. It will be a revelation to those who have known Habermas only through his theoretical writing to find his later interests in problems of legitimation and communication foreshadowed in this lucid study of the origins, nature, and evolution of public opinion in democratic societies.

Jürgen Habermas is Professor Emeritus of Philosophy at the University of Frankfurt and Professor of Philosophy at Northwestern University. He was recently awarded the 2004 Kyoto Prize for Arts and Philosophy by the Inamori Foundation. The Kyoto Prize is an international award to honor those who have contributed significantly to the scientific, cultural, and spiritual betterment of mankind.
