“The wise are not wise because they make no mistakes. They are wise because they correct their mistakes as soon as they recognize them.”

“From all wise men, O Lord, protect us.”

“A strange thing happened then. The Speaker agreed with her that she had made a mistake that night, and she knew when he said the words that it was true, that his judgment was correct. And yet she felt strangely healed, as if simply saying her mistake were enough to purge some of the pain of it. For the first time, then, she caught a glimpse of what the power of speaking might be. It wasn’t a matter of confession, penance, and absolution, like the priests offered. It was something else entirely. Telling the story of who she was, and then realizing that she was no longer the same person. That she had made a mistake, and the mistake had changed her, and now she would not make the mistake again because she had become someone else, someone less afraid, someone more compassionate.”

“It [seed of doubt] made Ender listen to what people meant, instead of what they said. It made him wise.”

“I know that you are wise. When you hear a true story, there is a part of you that responds to it regardless of art, regardless of evidence…You believe that the story is true, because you responded to it from that sense of truth deep within you. But that sense of truth does not respond to a story's factuality...[rather] to a story's causality - whether it faithfully shows the way the universe functions.”

“the seed of doubt was there, and it stayed, and every now and then sent out a little root. It changed everything, to have that seed growing. It made Ender listen more carefully to what people meant, instead of what they said. It made him wise.”

“...you seemed to be listening to me, not to find out useful information, but to try to catch me in a logical fallacy. This tells us all that you are used to being smarter than your teachers, and that you listen to them in order to catch them making mistakes and prove how smart you are to the other students. This is such a pointless, stupid way of listening to teachers that it is clear you are going to waste months of our time before you finally catch on that the only transaction that matters is a transfer of useful information from adults who possess it to children who do not, and that catching mistakes is a criminal misuse of time.”
