“I am a Roman,' he said to the king; 'my name is Gaius Mucius. I came here to kill you - my enemy. I have as much courage to die as to kill. It is our Roman way to do and to suffer bravely. Nor am I alone in my resolve against your life; behind me is a long line of men eager for the same honor. Brace yourself, if you will, for the struggle - a struggle for your life from hour to hour, with an armed enemy always at your door. That is the war we declare against you: you need fear no action in the battlefield, army against army; it will be fought against you alone, by one of us at a time.'Porsena in rage and alarm ordered the prisoner to be burnt alive unless he at once divulged the plot thus obscurely hinted at, whereupon Mucius, crying: 'See how cheap men hold their bodies when they care only for honor!' thrust his right hand into the fire which had been kindled for a sacrifice, and let it burn there as if he were unconscious of the pain. Porsena was so astonished by the young man's almost superhuman endurance that he leapt to his feet and ordered his guards to drag him from the altar. 'Go free,' he said; 'you have dared to be a worse enemy to yourself than to me. I should bless your courage, if it lay with my country to dispose of it. But, as that cannot be, I, as an honorable enemy, grant you pardon, life, and liberty.''Since you respect courage,' Mucius replied, as if he were thanking him for his generosity, 'I will tell you in gratitude what you could not force from me by threats. There are three hundred of us in Rome, all young like myself, and all of noble blood, who have sworn an attempt upon your life in this fashion. It was I who drew the first lot; the rest will follow, each in his turn and time, until fortune favor us and we have got you.'The release of Mucius (who was afterwards known as Scaevola, or the Left-Handed Man, from the loss of his right hand) was quickly followed by the arrival in Rome of envoys from Porsena. The first attempt upon his life, foiled only by a lucky mistake, and the prospect of having to face the same thing again from every one of the remaining conspirators, had so shaken the king that he was coming forward with proposals for peace.”

“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 only 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. I will devise the strategy of your army, and you will learn to be quick and discover what tricks the enemy has for you. Remember, boy. From now on the enemy is more clever than you. From now on the enemy is stronger than you. From now on you are always about to lose.”

“The philosophical arguments in favor of man’s ability to resist the slide into barbarism sound noble and rational in a classroom or at a cocktail party. But when the enemy is bearing down, bent on taking your life away from you, it’s not his country against your country, not his army against your army, not his philosophy against your philosophy-it’s the fact that that son-of-a-bitch is trying to kill you and you’d better kill him first.”

“Tommy cocooned me in his arms. The same arms that struck out to protect me, the arms that saved me.“In my life, I have never known, nor will I ever know, someone as strong and courageous as you, Elizabeth Irene Bradshaw,” Tommy whispers against my temple. I have no words, so I nod my head against his chest, hoping he understands my acceptance of his praise. “You honour me with your trust, baby girl. I am so very proud of you.”

“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.”

“This hand says you spend the rest of your life with me," he said, holding out his left hand, "and this one says I spend the rest of my life with you. Choose."She bit her lip, tears welling in her eyes. She took both of his hands in hers and he shuddered. "I will die protecting you," he says.There was a look of dismay on her face. "Just like a man of this kingdom, Finnikin. Talking of death, yours or mine, is not a good way to begin a-"Isaboe gave a small gasp when he leaned forward, his lips an inch away from hers. "I will die for you," he whispered.She cupped his face in her hands. "But promise me you'll live first. Because nothing we are about to do is going to be easy and I need you by my side.”
