In Part 1, Atticus teaches his children many lessons. Here are three significant lessons from the novel.
1. At the beginning of the novel, Scout starts school; however, she has a rough first day. Between a run-in with her teacher and Walter Cunningham, it's clear Scout has a lot to learn. Atticus teaches her a lesson about getting along with people. He tells her she can't understand a person's point of view unless "you climb into his skin and walk around in it." He's showing Scout how everyone has their own perspective on the world. It's important to honor and respect everyone's individual story, and don't be so quick to judge.
2. Perhaps one of the most important lessons in the first half of the novel comes from Atticus with his famous lines about how it's a sin to kill a mockingbird. While his point is about not causing senseless violence by bothering an innocent creature, this message is figuratively relayed in Part 2 of the novel when we learn about Tom Robinson's death, Dolphus Raymond's "alcoholism," and Boo Radley's selfless, kind acts. Atticus aims to show the concept of innocence and how prejudice can affect the lives of others.
3. At the end of Part 1, Atticus teaches Jem about the real meaning of courage when he makes Jem read to Mrs. Dubose every day. After she dies, Atticus reveals that she was a morphine addict who was weaning off of the drug. Because she wanted to be clean before she died, Atticus felt this was a real act of courage. He wants Jem to see that courage isn't just about being a strong man or shooting a gun; courage is about making choices with integrity every day.
