I think what's happening is, it's all - fantasy, science fiction, ghosts, trolls, whatever - finally being called, being admitted to be literature. The way it used to be, before the Realists and the bloody Modernists took over.
Ursula K. Le GuinIt is only when science asks why, instead of simply describing how, that it becomes more than technology. When it asks why, it discovers Relativity. When it only shows how, it invents the atom bomb, and then puts its hands over its eye and says, My God what have I done?
Ursula K. Le GuinWe will not know our own injustice if we cannot imagine justice. We will not be free if we do not imagine freedom. We cannot demand that anyone try to attain justice and freedom who has not had a chance to imagine them as attainable.
