I think that one of the main themes of the book is not to jude a book by its cover. Atticus is the main one trying to teach his kids not jude people and tyring to see things through there eyes. Such as when Atticus was talking to Scout in chapter 3 he said ". . . consider things from things from his point of view." (30) As the book goes on Scout and Jem start to learn what Atticus is tyring to teach them.
