Quote from : Ender's Shadow Book

Nero, you are an example to all the children on this shuttle. Because most of them are so foolish, they think it is better to keep their stupidest thoughts to themselves. You, however, understand the profound truth that you must reveal your stupidity openly. To hold your stupidity inside you is to embrace it, to cling to it, to protect it. But when you expose your stupidity, you give yourself the chance to have it caught, corrected, and replaced with wisdom. Be brave, all of you, like Nero Boulanger, and when you have a thought of such surpassing ignorance that you think it's actually smart, make sure to make some noise, to let your mental limitations squeak out some whimpering fart of a thought, so that you have a chance to learn.
