Answer:
theme
Step-by-step explanation:
This monologue here was from Atticus giving his final piece of moral advice to Scout in Chapter 3.
Atticus' advice was a theme for Scout in her development throughout the novel and also shows that Atticus himself is a follower of his own advice in that he always tries to "climb into the skin and walk around it" just to feel what someone else is feeling and live in sympathy, tolelrance and understanding towards others.
