“We don't know much about him. We do know that he came from a sperm meeting an egg. Actually, his name is Charles Mulholland. We don't know what he does, but he sure looks like he knows something.”

“You don't know old Charles as I know him. He's got into a queer set, and there's no knowing what mischief he's up to. He's perfectly capable of starting a revolution in Armenia or somewhere merely to see how it feels like to be a revolutionary. That's the damned thing about the artistic temperament.”

“We came to see Jace. Is he alright?"
"I don't know," Magnus said. "Does he normally just lie on the floor like that without moving?”

“"His brain pattern has been fully scanned. But it takes time for them to plot it out. We're all running around like lunatics while he just sits there!" Wisdom poked a stubby finger at the window. "We caught him easily enough. He can't have much, can he? But I'd like to know what it is. Before we euth him."
"Maybe we should keep him alive until we know."
"Euth in forty-eight hours," Wisdom repeated stubbornly. "Whether we know or not. I don't like him. He gives me the creeps."”

“He who does not know how to look back at where he came from will never get to his destination.”

“He looks at me in such a way that I know for sure-he's never looked at another girl quite like this.
And the I'm in his arms, and we're hugging and kissing, and we're both shaking, because we both know-this is the night we become real.”

“You know that color does not matter to me. I want to know other things about a man. Is his word good? Does he meet his obligations? Does he do honest work? Is he brave? Will he stand up and be counted?”

“What do we know? What do we really know? He licks his dried cracked lips. We know this apodictic rock beneath our feet. That dogmatic sun above our heads. The world of dreams, the agony of love and the foreknowledge of death. That is all we know. And all we need to know? Challenge that statement. I challenge that statement. With what? I don't know.”

“When I was dating Bert (McCracken), we were like two best friends. And we ended up doing everything together and it was so much fun. It was a really good time. And this (2003) has been such a horrible year for me that I sometimes thought I'd like to go back to that and be with Bert, but then I suddenly realised that's not what I wanted. I don't even know him as a person. And more than that, I don't even like him. It's like they say that you don't know the devil but you know he's evil. I know what that means — I don't know Bert but I know that I don't ever want to see him again.”

“Why do we know what we know and why don't we know what we don't know? What should we know and what shouldn't we know? How might we know differently?”
