Lee explores the theme of bravery in section 1 between several people, Scout, Jem, Atticus, Mrs Dubose and other people in Maycomb. There is different kinds of bravery throughout the novel it goes from being an immature bravery and slowly becomes a mature bravery.
When Scout, Jem and Dill are younger their bravery is very different to what an adult’s view of bravery would be.

Atticus got Jem to read to Mrs. Dubose as he misbehaved but he also wanted him to learn what true bravery was. He wanted to show Jem that a brave person is not "a man with a gun in his
