This paper is aimed at interpreting Ralph Waldo Emerson, Henry David Thoreau and Herman Melville's view of nature clearly by briefly analyzing their representative works. And this paper is composed of four parts. Chapter Ⅰ will make a detailed analysis of Emerson's view of nature and make a further investigation of his view by analyzing his work Nature.Chapter Ⅱ is about Thoreau's view of nature and his attitude to nature through his work Walden. Chapter Ⅲ firstly makes a brief introduction of Melville's view of nature and then interprets it by explaining the symbolic meaning of main characters' names in his famous work Moby-Dick. And the last chapter makes a simple comparison among their views of nature to give a further understanding of the view of nature in American Literature. 展开更多

Herman Melville(1819-1891) is one of the famous writers in the history of American and world literature. Moby Dick is one of the masterpieces of Melville, and it is also his most famous ocean works in his late life. Moby Dick describes a story on Captain Ahab took revenge on white whale. This paper will discuss Captain Ahab's paranoid personality, and reveal how Melville reflected in the works: coexistence between human and nature. A brief description will be provided for the writer's life and his works, and then I will discuss Captain Ahab's paranoid personality through his whaling capturing process. Then, I will discuss obtaining principles of Captain Ahab, Mate Starbuck, Crew Ishmael, and reveal the Captain's tragic causes and reflected thinking. Finally, I will make a conclusion only if people adopt right obtaining principles to natural resources, could we live with nature altogether. 展开更多
