Atticus Finch's character, in Harper Lee's To Kill a Mockingbird, serves as the moral compass. Both his children, Scout and Jem, and the community look to Atticus during challenges which speak to moral dilemmas and conflict. Many of his quotes can be identified as ones which both speak to his leadership and morality.
One quote which speaks to his role as a leader is as follows:
The one thing that doesn’t abide by majority rule is a person’s conscience.
Here, Atticus is speaking on the importance of being an individual, even when it seems that everyone is against you. This quote allows readers to understand a very important aspect of the role of a leader: it may not always be the best to follow the majority. In some circumstances, the majority is wrong, and it is the individual who makes it right.
Another quote which illustrates Atticus's leadership is found in the following:
You just hold your head high and keep those fists down. No matter what anybody says to you, don’t you let ‘em get your goat. Try fighting with your head for a change.
Here, Atticus is stating the importance of one keeping calm. Atticus knows that people will challenge those who do not conform to "majority rule." Under these circumstances, one must be able to remain calm and not take things to a physical level. Instead, Atticus offers advice regarding using one's words to win the battle. Good leaders know that violence does not always solve problems.
Leaders understand the importance of courage.
I wanted you to see what real courage is, instead of getting the idea that courage is a man with a gun in his hand.
For Atticus, he does not want his children to think that a gun is the means to an end in every problem which arises. Real courage, the characteristic of a true leader, is understanding that you may not always win. Yet, even with this knowledge, one must take on the challenge.
Finally, Atticus's (probably) most notable line identifies the importance of understanding another person's point-of-view:
You never really understand a person until you consider things from his point of view.
This line speaks to Atticus's understanding of tolerance and perspective. As a leader, it is important to understand why others make the decisions in their lives that they do. One must know far more about another person than simply the action itself to truly define who someone really is.
