The three themes of the book, The Adventures of Huckleberry Finn, that stood out to me the most to me in the second half of the book were slavery, Blacks vs. whites, and fraud. I chose these three themes because of all of the themes I could think of, these could be the most closely related to the book with the most details and examples there to support my information, and also because they were the easiest. .
First I will address slavery. Slavery is a large issue in this book. There is always someone in the book talking about their "nigger". In many places in the book, well actually in almost all places in the book, black people or "niggers" are referred to as property (example: "my nigger, and his nigger"). This fact is also supported by the fact that Jim wants to buy his wife and children from their owners. When Jim is running with Huck he is wanted with a cash reward for his return and it is not because he has murdered anybody at first it is because he has run away from his owner. I thought that Huck is the only white person in the book that doesnt hate black people. Well I have found out that all of Tom Sawyers family has a heart for a well mannered black person as well (example: when Aunt Sally found out that Jim helped Tom the way he did she did everything she could to make him comfortable by means of food and shelter and water etc.). Here is a final thought. Jim was treated like any other slave maybe worse for the whole book except for when everybody found out he had been deemed free, then everybody completely changed.
Second I will address the conflict of blacks vs. whites. This is one of the biggest impacting conflicts in the book, and not because it was a huge conflict but because it lasted the whole book. Basically everything that happens in the book is related some how to the way white people feel about blacks and vice versa.
