In this video the focal contemporary theorist is Habermas, but in order to understand him better I chose to start with two of the first generation Frankfurt School founders: Walter Benjamin and Theodore Adorno and then go into the Theory of Communicative Action of Jürgen Habermas. I thought that the best way to understand their approach is through the "music dabate" between them. I use a song by Joan Baez sang during anti-Vetnam War meetings.
