约瑟夫.康拉德在《黑暗的心灵》中使用了框架式的叙事方法:第一人称叙述者我→主人公第一人称叙述者马洛→第一人称叙述者我。这种叙事方法不只是追求外在形式的改变。叙事视角的转换、叙事距离的把握反映了作者充盈着矛盾的丰富思想。本文从康拉德生平经历及其思想道德意识和艺术主张、小说中不同叙述者的功能、叙事距离产生的效果等方面分析了框架式叙事的原因。 Joseph Conrad used the framework narrative method in “The Dark Heart”: the first-person narrator I → the first-person narrator Marlow → the first-person narrator I. This narrative approach does more than just pursue external changes. The transformation of narrative perspective and the distance between narratives reflect the rich and contradictory ideas of the author. This article analyzes the reasons of frame narration from the experience of Conrad and his ideological and moral consciousness and artistic proposition, the function of different narrators in the novel and the effect of narrative distance.
