If you have missed my talk “Radikal emanzipatorisch. Vernunftkritik als kritische Theorie” from the lecture series “100 Jahre Soziologie an der Goethe-Universität”, you can now watch it online in a video.
If you prefer to read, the basis for the talk was my paper “Should Critique be Tamed by Realism? A Defense of Radical Critiques of Reason”.
