How has the author used both Jim and Huck to explore the themes of the novel?
One of the major ways that Twain explores the themes of Racism and Slavery is the way that Huck treats Jim and the way his attitude towards him changes throughout the novel. In numerous situations Huck has to question the way that other people treat Jim and the pre-conceived notions that he had about Jim as well are challenged as they ride the river together and deal with numerous sticky situations.
Jim is also key to the investigation of these themes as Twain uses a variety of methods to question and explore the ideas that many people had about slaves and African Americans in general. Jim demonstrates time and time again his great intelligence, practical and moral, and Twain uses this accuity in contrast with his child-like suspicion to draw particular attention to it.
