Huck teaches himself that black people are essentially different from white people. He expresses this through one quote that is written, "when we was ready to shove off we was a quarter of a mile below the island, and it was pretty broad day; so I made Jim lay down in the canoe and cover up with a quilt, because if he set up people could tell he was a nigger a good ways off. " (Pg. 66) Huckleberry Finn assumes that people can distinguish a black person from a distance, implying a great difference in races. Twain as well, uses satire to show how hypocritical a "good Christian woman" can be when it comes to owning slaves as property.
He satirizes again in the novel through the idea of family feuds, The Shepardsons and Grangerfords. Buck wants to kill the Shepardsons so bad, though he hardly knows why. The Boggs and Sherburn incident is another example. When Sherburn killed Boggs for continued provocation, the town felt the need to lynch Colonel Sherburn for his crimes. Sherburn spoke to them about their nature and how they wouldn't be able to stand against him if they weren't a group of people. Twain satirizes the idea of lynching and the human nature that goes along with whatever the crowd decides as opposed to what each individual thinks or believes.
The differences between Huck and tom begin by how they were raised. Tom is a rather well to do member of high society, and Huck, who was raised by his drunk father. Such led to Huck's growing up in a disordered environment that commonly forced him into freedom. Tom was raised, with a well-ordered civilization. Huck is able to easily fashion a story, to suit the needs of any situation, such as when he dressed up as a girl, in order to get information about a murder. Furthermore, he cannot comprehend Tom's nearly religious dedication to the way things are supposed to be.
Tom follows society, and don’t break the laws of the land. Huck, on the other hand, has no use for society and its inflexible ways, leading him to follow his own path when judgment leads him that way. As well, Tom follows religion because he is told to, Huck can find no use for a book about a group of dead people. His decision to sacrifice his soul in order to save Jim, his beloved slave friend, not only shows his belief that religion holds little use for him, but also a willingness to go against the majority of the world in a way that Tom would never do. Pooty soon I'll be a-shout'n' for joy, en I'll say, it's all on accounts o' Huck; I's a free man, en I couldn't ever ben free ef it hadn' ben for Huck; Huck done it. Jim won't ever forgit you, Huck; you's de bes' fren' Jim's ever had; en you's de ONLY fren' ole Jim's got now. ". Huck is the only white man who's ever kept his promises to Jim,that is what makes him his best friend. Tom and Huck are both a clever character, which can solve any kind of problems around them. They both have a very strong sense of adventure. I think this one trait along, with their similar ages is what makes them friends.
