Daniel Barreto, professor at the University of Las Palmas de Gran Canaria, and Roberto Gil, professor at the University of La Laguna, will introduce us, on the one hand, to Leo Löwenthal, the sociologist of literature from the Frankfurt Institute for Social Research, and on the other hand, to Enrique Dussel, who offers a decolonial approach to some of the theoretical intuitions developed by the core of Critical Theory.
