Scout is clearly the child of Atticus Finch despite her pugnacious tendencies as a little girl. That she writes her memories of childhood and sorts them out is indicative of the highly rational child that she truly is during the narrative. In the early chapters, her attempts to reason with Miss Caroline Fisher about the Cunninghams and the Ewells stand out as they indicate her innate proclivity to logic.
Indeed, this scene sets the stage for Scout's dominant rationality. For, she possesses a logic that emerges throughout the novel as Scout asks her father about entitlement and later during the mob scene she applies its priniciples to Mr. Cunningham, she wonders why her father is nice to Mrs. Dubose, she does not understand why she is punished for bashing her cousin after he has insulted her father's honor, she observes the trial of Tom Robinson and deduces much on her own and from recalling her father's instructions on witnesses. Finally, it is Scout's great logical reasoning that puts together all her childhood lessons as she stands looking from a different perspective on Boo Radley's porch in the conclusion:
Atticus was right. One time he said you never really know a man until you stand in his shoes and walk around in them. Just standing on the Radley porch was enough.
