The ``Frankfurt School refers to the members associated with the Institut fur Sozialforschung (Institute for Social Research) which was founded in Frankfurt in 1923. The work of this group is generally agreed to have been a landmark in twentieth century social science. It is of seminal importance in our understanding of culture, progress, politics, production, consumption and method.This set of six volumes provides a full picture of the School by examining the important developments that have occured since the deaths of the original core of Frankfurt scholars. All the major figures-Adorno, Horkheimer, Marcuse, Benjamin-are represented. In particular, the important post-war work of Jurgen Habermas is fully assessed. The collection also covers the work of many of the minor figures associated with the School who have been unfairly neglected in the past, resulting in the most complete survey and guide to the oeuvre of the Frankfurt School.
