The idea that man is condemned to freedom was an unwavering certainty for capitalism critic André Gorz. Not only does his sensational suicide in 2007 testify to this, but so does the socio-political imagination evident in his writings. This fundamental attitude is also reflected in the debates he had with his mentor Jean-Paul Sartre, as well as in his engagement with Marxism. André Häger dedicates individual studies to the life and work of André Gorz and demonstrates, among other things through unpublished letters and conversations, that the political interventions of the French social philosopher are driven by existentialist motives to a much greater extent than previously assumed.
