This interview of Andrew Feenberg by Bruna Della Torre de Carvalho Lima and Eduardo Altheman Camargo Santos explores a number of issues: What is the relationship between theory and practice today? Is there any longer a place for Orthodox Marxism? What is the relationship between critical theory and other contemporary intellectual work? How are we to evaluate the work of the Frankfurt School today? The interview provides Feenberg with the possibility to offer direct and clear answers to these and other questions of the continued relevance of critical theory.
