问答题

What is a novel I say: an invented story. At the same time a story which, though invented, has the power to ring true. True to what True to life as the reader knows life to be or, it may be, feels life to be. And I mean the adult, the grown-up reader. Such a reader has outgrown fairy tales, and we do not want the fantastic and the impossible. So I say to you that a novel must stand up to the adult tests of reality.
You may say: "If one wants truth, why not go to the literally true book Biography or documentary, these amazing accounts of amazing experiences which people have. " Yes, but I am suggesting to you that there is a distinction between truth and so-called reality. The novel does not simply recount experience; it adds to experience. And here comes in what is the actual livening spark of the novel: the novelist’s imagination has a power of its own It does not merely invent, it perceives. It intensifies, therefore it gives power, extra importance, and greater truth to what may well be ordinary and everyday things.
