.
"You can turn around and go home again, Walter," Atticus said pleasantly. "Heck Tate's around here somewhere.".
The reader is able to see from Atticus" dialogue, the calm and humane character that he is; we see that his courage is used with words, in that he doesn't resort to or condone violence in any situation.
Another technique Lee used, in order to signify Atticus" courage in the jail scene, was the use of juxtaposition, which shows the contrasting images of Atticus, seen as being equitable and honest, to the lynch mob, reflecting the corrupting men. The light in which Atticus sets up for himself becomes a symbol of what is courageous and honest, and throughout the scene Atticus remains under the light. In contrast, the lynch mob are described to be seen as dark shadows, always lingering in the darkness.
"I pushed my way through dark smelly bodies and burst into the circle of light.".
The light is symbolic of Atticus" character, which is depicted by both the reader and the other characters in the scene.
Therefore, we see that this passage was very successfully in achieving the purpose of revealing the theme of courage, as seen in Atticus, to the reader.
Including the Jail incident in her novel allowed Lee to further explore the central theme of the innocence of child mentality, and the growth from innocence to understanding. Constructing the text in the first person perspective, allows the reader to have a greater understanding of Scout and hence the ability to comprehend why she behaves the way she does. It signifies Scouts innocence when she runs to see her father, not understanding why he displays fear and disapproval at the sight of her.
"I thought he would have a fine surprise, but his face killed my joy.".
Being as innocent and naive as she is, Scout interprets Atticus" fear as being anger, and furthermore, feels embarrassed instead of frightful when discovering she has leaped in the midst of people she didn't know.
