“No one is to be called an enemy, all are your benefactors, and no one does you harm. You have no enemy except yourselves.”

“More than those who hate you, more than all your enemies, an undisciplined mind does greater harm.”

“An enemy, Ender Wiggin," whispered the old man. "I am your enemy, the first one you've ever had who was smarter than you. There is no teacher but the enemy. No one but the enemy will tell you what the enemy is going to do. No one but the enemy will ever teach you how to destroy and conquer. Only the enemy shows you where you are weak. Only the enemy tells you where he is strong. And the rules of the game are what you can do to him and what you can stop him from doing to you. I am your enemy from now on. From now on I am your teacher.”

“Fear is the trick of the enemy. And your enemy comes in many robes. But he has only one face. You know his face. You've seen it many times. You need not fear it. In your heart, you know you will triumph and you will defeat your enemy with the one weapon that you have inside you that he cannot touch--truth.”

“One has to understand what the enemy is all about: the enemy's history, the enemy's culture, the enemy's aspirations. If you understand these well, you can perhaps move towards peace.”

“Memo to extreme partisans: If you can't bring yourselves to love your enemies, can you at least learn to hate your friends?”
