Final answer:
Atticus considers Mrs. Dubose's struggle with her addiction a true act of courage, emphasizing moral strength over physical force.
Step-by-step explanation:
Atticus's statement that Mrs. Dubose is a model of real courage reflects the idea that true bravery isn't about physical prowess or weaponry, but rather the strength to confront and overcome personal challenges. According to Atticus, courage involves mental fortitude and ethical steadfastness, particularly in the face of adversity or temptation. Mrs. Dubose's battle with her morphine addiction, despite knowing that she will pass away, showcases this type of courage—the will to fight personal battles and uphold one's principles even when the outcome is bleak or the challenge seems insurmountable. Atticus's belief aligns with the broader themes in Harper Lee's To Kill a Mockingbird, which suggest that moral strength is more commendable and impactful than physical force alone.
