Gerhard Hanloser discusses a newly published book by Domenico Losurdo and critically questions the unanimously positive response that this work on the history of Western Marxism has received so far in parts of the left public. Hanloser discovers numerous ambiguities and points to Losurdo’s misinterpretations of Western Marxist thinkers. Hanloser takes a critical stance towards apologies for authoritarian forms of socialism in China and postcolonial states.
