“The Duke would not pay for the works. He says that the Castle can never be taken. That is called hubris, Giacomo, the belief that you are never wrong. Believing you are never wrong is an error that afflicts great men. I have learned that to be right you must first be wrong many times. Without making errors--and learning from them--a man cannot find the truth.”

“You must never feel badly about making mistakes ... as long as you take the trouble to learn from them. For you often learn more by being wrong for the right reasons than you do by being right for the wrong reasons.”

“Learning is never wrong. Even learning how to kill isn't wrong. Or right. It's just a thing to learn, a thing I can teach you. That's all.”

“There is no right or wrong way to write a novel. Each journey is different for every individual work and for every writer. The first error is never to begin; the second is never to finish.”

“...In another time, What cannot be seen will define us, and we shall be prompted To say that language is error, and all things are wronged By representation. The self, we shall say, can never be Seen with a disguise, and never be seen without one.”

“Two wrongs never make a right. But that never means that you can continue with your wrongs.”
