In fact I don't think of literature, or music, or any art form as having a nationality. Where you're born is simply an accident of fate. I don't see why I shouldn't be more interested in say, Dickens, than in an author from Barcelona simply because I wasn't born in the UK. I do not have an ethno-centric view of things, much less of literature. Books hold no passports. There's only one true literary tradition: the human.
