"In the 19th century it was basically nationality and people trying to define their nationalism and create states which would reflect their nationalism. In the 20th century, ideology came to the fore, largely, but not exclusively, as a result of the Russian Revolution and we have fascism, communism and liberal democracy competing with each other. Well that's pretty much over."

One of the reasons [William] Shakespeare is so endlessly fascinating is that you can look at that figure from about 10 different angles: Caliban in Shakespeare's day was probably viewed as a sort of comic, barbarian type, but into the 19th century there were productions where Caliban was the hero. He's a potential rapist of a minor. Is that a good thing? No, it is not. On the other hand, Prospero's got him cooped up in a cave and tortures him if he doesn't do what Prospero wants. Is that a good thing? No. Shakespeare doesn't let you off easy.
