Marlow speaks of his encounter with Kurtz as being at "the farthest point of navigation and the culminating point of my experience." Explain exactly n what sense Marlow's encounter with Kurtz may be regarded as the culminating point of Marlow's understanding of the nature of man. How far is the meaning of the story concerned with the evil of man in his essential nature? How far is it a story about the disease of modern, social man in history?
