“You never really understand a person until you consider things from his point of view... Until you climb inside of his skin and walk around in it.” - Atticus Finch

Such a simple statement carries such weight, especially in the situation in which it is said. Spoken by Atticus Finch near the beginning of the novel, this quote summarizes the theme of the entire book of To Kill a Mockingbird. Atticus is attempting to instill a lesson in his daughter, Jean Louise "Scout" Finch, but the full meaning does not become apparent to her until the end of the novel, until after she has seen the persecution of Tom Robinson and the blind hate that drove it. 

One of the main themes throughout To Kill a Mockingbird is to seek unity between all peoples.

 If one were to consider any quote from To Kill a Mockingbird to be wise, this would have be the one. The lesson portrayed applies in any and all situations; consider others' situation before you make judgments about them. Throughout the world, if we just considered others' views, there would be no more discrimination by race, class, lifestyle, or any other factor. There would be no more mindless murders of innocent people, or acts of terrorism by crazed religious fanatics. The day we look through each others' eyes is the day the world truly lives as one.
