Answer:
In Chapter 11, when talking with his children, Atticus speaks on the topic of courage.
What he wants to point out in this line is that his shooting skills (which he does not publicly show until he needs to kill a mad dog) do not represent real courage and are not a matter for pride. Courage is consisted of different things, in his view, such as Mrs. Dubose's refusal to take morphine before she dies. In this way, even though she dies, she fights off a morphine addiction and does the right thing.
