A theme is a fundamental and often universal idea explored in a literary work. In the book To Kill a Mockingbird, there are three main themes that generally appear throughout the story. These themes will help connect the loose ends of the story and help readers understand the meaning of this story. The first theme is the coexistence of good and evil throughout history. The way the book shows the moral nature of people, basically their good and bad sides. The book promotes this theme by using the transformation of Scout and Jem's view of childhood innocence, in which they believe everyone is good, because they have never been exposed to evil, to a more adult vision, in which they were exposed to evil. many types of evil and must apply it to their thinking. An important subtheme of this book concerns the danger that hatred, prejudice, and ignorance pose to many innocent people. The people in the book are Boo Radley and Tom Robinson. These two are unprepared for the evil they have been exposed to, and as a result, they have been mentally destroyed. Jem also experiences the same affect when he discovers the evil of racism, in which his faith in justice and humanity is lost. However, Scout maintains her faith in justice and humanity, as the case had no effect on her. In this book, the voice of morality is Atticus Finch, who already experiences and understands evil, but does not lose faith in humanity's ability to be good. He understands that everyone basically has good and bad qualities, but that it is more important to appreciate the good ones. The worldview is that of the middle of the paper which is a little more successful than that of most white people in Maycomb. The stark social divisions revealed by the book show how irrational and dangerous the adult world is, such as when Scout struggles to understand why Aunt Alexandra won't let her talk to young Walter Cunningham. The corruption of Maycomb's social ladder shows how badly the Great Depression hit the town and how it greatly affected its residents.
