Peace demands the most heroic labor and the most difficult sacrifice. It demands greater heroism than war. It demands greater fidelity to the truth and a much more perfect purity of conscience.
Heroism is the act of being a hero. This is a state of being or action that shows true courage in the face of adversity, and a willingness to risk everything to do the right thing in a specific situation. During 9/11 many people showed true heroism, like the passengers on the flight who fought back and prevented further damage to our country. Soldiers show heroism every day, by putting their lives on the line for people who may not even appreciate it and protecting our freedoms.
