The Adventures of Huckleberry Finn shows the growth of consciousness of an innocent young orphan into an adolescent who understands the evil around him.

The primary theme of the novel is the conflict between civilization and "natural life." Huck represents natural life through his freedom of spirit, uncivilized ways, and desire to escape from civilization. He was raised without any rules or discipline and has a strong resistance to anything that might "sivilize" him. This conflict is introduced in the first chapter through the efforts of the Widow Douglas: she tries to force Huck to wear new clothes, give up smoking, and learn the Bible. Throughout the novel, Twain seems to suggest that the uncivilized way of life is more desirable and morally superior. Drawing on the ideas of Jean-Jacques Rousseau, Twain suggests that civilization corrupts, rather than improves, human beings.
