[Science fiction] really does deal with issues far more serious than those realistic fiction deals with; real problems about human destiny and so on. Do you remember that story about the man who meets a female monster landed from another planet with all its cubs hanging round it? It’s obviously starving, and he offers them thing after thing to eat; they immediately vomit it up, until one of the young fastens on him, begins sucking his blood, and immediately begins to revive. This female creature is utterly unhuman, horrible in form; there’s a long moment when it looks at the man – they’re in a lonely place – and then very sadly it packs up its young, and goes back into its space-ship and goes away. Well now, you could not have a more serious theme than that. What is a footling story about some pair of human lovers compared with that?
