Atticus and Calpurnia represent the theme of wisdom because they try and look at other’s perspectives and put themselves in their shoes, and they think it’s wrong to judge other’s because of their differences.
Atticus is speaking to Scout, “Don’t say nigger Scout. That’s common.... ‘s what everybody at school says... From now on it’ll be everybody less one” (Lee 85).
Calpurnia says to Scout, “There’s some folks who don’t eat like us, but you ain’t called on to contradict ‘em at the table when they don’t” (Lee 27).
Being wise involves not being biased. This is a big deal in the book because of racism and the social classes during the Great Depression.
