德国文论家沃尔夫冈·凯瑟在《谁是小说叙事人?》一文中指出:“所有属于叙事艺术的作品都有一个叙事人。史诗、短篇、中篇小说和轶事都是如此。所有做父母的都知道,在给孩子们讲故事时必须改变自己的身份。他们必须放弃成年人的理智,使得他们眼里诗的世界和奇迹都是真的。叙事人必须相信这一点,哪怕他讲的故事能篇都是谎话。如果他不相信那是真的,他就不会说谎。” The German literary writer Wolfgang Cather pointed out in his article “Who is the Narrative Person of the Fiction?” "All works belonging to narrative art have a narrator, and epics, short stories, novella and anecdote So, all parents know that they must change their identity when telling their children, and they must give up the intellect of adults so that their world and miracles are real in their eyes, and the narrator must believe it Even if he can tell the story of the story is a lie, if he does not believe that is true, he would not lie.
