Here is a link to Harry Cleaver's very detailed response to the review of his book 'Reading Capital Politically' in a copy of the journal 'Aufheben';

I read Aufheben's review a while back and whilst it led me to read Cleaver's book(as well as Steve wright's book on Italian Autonomist Maxism-which is also covered in the same 'review') there were a number of things written in their article that I was not impressed by eg.their discussion of class. Cleaver's response is extremely detailed -with comments made almost paragraph by paragraph- and is well worth reading for anyone interested in autonomist marxism.
What problems did you have with their discussion of class?
