“If you don’t believe in the world, and if there is no love in it, then everything is phony. No matter which world we are talking about, no matter what kind of world we are talking about, the line separating fact from hypothesis is practically invisible to the eye. It can only be seen with the inner eye, the eye of the mind.”

“Closing your eyes isn't going to change anything. Nothing's going to disappear just because you can't see what's going on. In fact, things will even be worse the next time you open your eyes. That's the kind of world we live in. Keep your eyes wide open. Only a coward closes his eyes. Closing your eyes and plugging up your ears won't make time stand still.”

“I have a million things to talk to you about. All I want in this world is you. I want to see you and talk. I want the two of us to begin everything from the beginning.”

“You have to look!" Johnnie Walker commanded. "That's another one of our rules. Closing your eyes isn't going to change anything. Nothing's going to disappear just because you can't see what going on. In fact, things will be even worse the next time you open your eyes. That's the kind of world we live in, Mr. Nakata. Keep your eyes wide open. Only a coward closes his eyes. Closing your eyes and plugging up your ears won't make time stand still.”

“Its Barnum & Bailey world just as phony as it can be,But it would't be make-believe if you believed in me”

“Math is like water. It has a lot of difficult theories, of course, but its basic logic is very simple. Just as water flows from high to low over the shortest possible distance, figures can only flow in one direction. You just have to keep your eye on them for the route to reveal itself. That’s all it takes. You don’t have to do a thing. Just concentrate your attention and keep your eyes open, and the figures make everything clear to you. In this whole, wide world, the only thing that treats me so kindly is math.”

“You said you're going far away," Tamaru said. "How far away are we talking about?""It's a distance that can't be measured.""Like the distance that separates one person's heart from another's.”
