Mark Twains The Adventures of Huckleberry Finn tells the story of Huck and Jim, a white boy and a black slave, who run away in search of freedom. The first part of this thesis is the literature review. Focus is put on the review of the freedom theme and analysis. The main body starts from the second part which divides Hucks escape into three stages:Hucks aversion and tolerance to the civilized society before escape, his decayed initiative in the pursuit of freedom during the escape and his ret to search for freedom at the end. Through above analysis, the conclusion is reached:Mark Twains view of freedom in this novel is vague and ambiguous, and there are many paradoxes in it. He longs for personal freedom but cannot escape from the secular society. He is willing to resist repressing civilization but unable to revolt its invasion.
