Michael Dening: Who was Antonio Gramsci? And how did he end up filling 3000 notebook pages with such remarkable analysis and theorization around the sorts of politics that communism required in the 20th century? He says one of the most intriguing moments in the prison notebooks is when he writes a whole set of notes on how one might think about Marx. One of his powerful arguments, this will come around to who he is, is to say Marxism is a kind of historic change in our conception of the world not unlike the Renaissance or the Protestant Reformation.
