Guernica has an interview with Ursula K. Le Guin (her collection, The Birthday of the World is reviewed here):
Guernica: Why do you think so much new literary fiction takes on fantasy and science fiction, and what sort of thoughts do you have about this? Or popular culture, for that matter? Why do you think we’re reaching for aliens, ghosts and vampires so often these days?
Ursula K. Le Guin: I don’t think we’re doing so, any more than we always did! 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. Joshua fit the battle of Jericho, and the walls came atumblin’ down.
