Twain here shows the key for the Negros to get their freedom which is they themselves must be united first instead of cheating each other.Although Jim is affected deeply by long term slaveholding system, he longs to earn his own and his family’s freedom. When knowing Miss Waston wants to sell him at 800 dollars, he chooses to run away, because his selfrespect tells him that he can not bear to be treated as an object and sold from place to place. In his inner, he thinks that the slaveholding system is unreasonable and he wants to escape from it.2. 3 Exposition of objectivity One of the features of realism is that realism emphasizes objectivity and offers an objective rather than an idealistic view of human nature and human experience. At that time, many people thought of that period as a new “Golden Age”. But the gold was only on the surface. As a matter of fact, American society was filled with crime and social injustice (Liang Qing, 1994).Mark Twain believes in democratic thoughts and feels disappointed and angry at the omnipotence of money in his society. He reveals the dark side of the American society straight from the shoulder such as fatuity, money worship and so on. Fatuity In Chapter 18, we see the unbelievable behaviors between two aristocratic families. Just for a ridiculous notion of family honor, Grangerfords and Shepherdsons fight generation after generation. When Huck asks his peer Buck for the reason, Buck answers: “A feud is this way: A man has a quarrel with another man, and kills him。 then that other man’s brother kills him。 then the other brothers, on both sides, goes for one another。 then the cousins chip in – and by and by everybody’s killed off, and there ain’t no more feud. But it’s kind of slow, and takes a long time”(2003, p130).From these words, we can see that it is no one but the socalled civilized society that is so indifferent to people’s lives. Buck, who is just a little boy, is inculcated with the ideas of revenging others and the feud will be deeply rooted in his mind. It is so miserable and satirical for Buck to kill his enemies. Under the effects of his ancestors, he even can not distinguish good from bad, right from wrong. Just as Buck’s saying, the feud ends when all people are dead. At last, Grangerford’s four sons are killed and the situation gets worse, which displays the brutality and stupidity of patriarchal clan system.In Chapter 21, Boggs is killed cruelly by Sherburn. It is such a terrible murder, while other people just treat it as a topic for talking after meals. Some even say: “Say, now, you’ve looked enough。 you fellows。 ‘tain’t right and ‘tain’t fair for you to stay that all the time, and never give nobody a chance。 other folks has their rights as well as you”(2003, p174). All of these show these socalled educated and civilized people in such a democratic society are so impassible, tiresome and vulgar. It is no others but their fatuity that has caused these terrible things happen. Money worshipIn American society, it is well known money is situated at a highest position and people exclusively concern themselves with money. Money worship severely permeates every corner of the country and bees the source of crime, degeneration and egoism. In Chapter 5, Pap, Huck’s father, who does not take care of Huck at all, tells Huck that he’d cowhide Huck till Huck is black and blue if Huck does not give some money to him. In fact, Pap could nearly beat his son to death in order to get money. Also, in Chapter 25, the duke and the king pretend to be the rich dead man Peter’s brothers and take advantage from Peter’s death to get money. Therefore, the king pretends to be a deaf and expresses his sadness with his body language while the duke pretends to the other brother of Peter. In order to get money, the two swindlers make many bad lies and hurt the innocent people. There is no doubt that the three poor girls of the Wilks are the most miserable ones. Therefore, the conning of the Wilks daughters is the cruelest fraud pulled off by the Duke and Dauphin. In order to gain the trust from Mary Jane and other people in the town, the two swindlers cry so sadly in the mourning hall that everyone believes that they are the relatives of the Wilks. “When they got there they bent over and looked in the coffin, and took one sight, and then they bust out acrying so you could’a’ heard them to Orleans, most” (2003, p197). And “and then for three minutes, or maybe four, I never see two men leak the way they done” (2003, p197). These words convey directly that these two swindlers are so sick and disgusted just because of money.It is very sarcastic that there is a sharp contrast between Huck’s innocent child world and the American society. Huck regards money as rubbish. He asks Judge Thatcher to take all his money and he steals the 6,000 dollars from the two swindlers to return them to Mary Jane. There is no doubt that Huck’s behavior is powerful challenge to money worship.3. ConclusionThe greater part of America’s literary realism is limited to optimistic treatment of the surface of life. Yet the great America’s realist, Mark Twain moves well beyond a surface portrayal of the 19th century America. Twain describes the breadth of American experience as no one has ever done before and he created The Adventures of Huckleberry Finn, a masterpiece of American realism that proves to be one of the great books of world literature.The realism of Huckleberry Finn is disclosed alternately by the thread of Huck’s consciousness, not yet e to full awareness of how fully implicated in events it is, and by the palpable events and seem randomly strung upon it, namely, by the narrative itself (Quirk Tom,2000). Using his own principles for realistic writing, through Huckleberry Finn, Mark Twain reveals the ugly realities of American civilized society, such as the brutality and poverty of life a
