“But I'm three times your age or more and my brain is worn out and full up. I don't have much room to tuck new things square inside; they just cling to the outside for a while and drop off.”

“I have begged and she hasn't answered. The whales are swimming deep inside me and she doesn't help. I need help. All the monsters in the world are inside me instead of outside me. I've been tricked and trapped and they are inside my walls not outside my walls inside with me and she won't help me. When I stop thinking about a muscle it shakes. When I stop thinking about a fear it leaps at me. I'm drowning but the lake keeps getting deeper and deeper and deeper and I don't know how to get out the walls go up forever and I can't climb over and I can't break through and she won't talk to me.”

“Earthborn animals do this thing, inside their brains—a sort of firing-off of synapses, controlled insanity. While they’re asleep. The part of their brain that records sight or sound, it’s firing off every hour or two while they sleep; even when all the sights and sounds are complete random nonsense, their brains just keep on trying to assemble it into something sensible. They try to make stories out of it. It’s complete random nonsense with no possible correlation to the real world, and yet they turn it into these crazy stories. And then they forget them. All that work, coming up with these stories, and when they wake up they forget almost all of them. But when they do remember, then they try to make stories about those crazy stories, trying to fit them into their real lives. …They change what their stories mean. They transform things so that the same memory can mean a thousand different things. Even from their dreams, sometimes they make up out of that randomness something that illuminates everything. …Even if the vast majority of them are wrong, even if ninety-nine of every hundred is stupid and wrong, out of those thousands of ideas that still leaves them with a hundred good ones. That’s how they make up for being so stupid and having such short lives and small memories.”

“I don't give up and I don't wear down. I'm not just rock, I'm diamond.”

“Nothing that is new is ever new twice. While things that are true are still true the next time; truer, in fact, because they have been tested, they have been tasted, and they are always ripe, always ready...”

“Are you all right, Sir?" asked Hezekiah."Just fighting over old battles in my mind," said John. "It's the problem with age. You have all these rusty arguments, and no quarrel to use them in. My brain is a museum, but alas, I'm the only visitor, and even I am not terribly interested in the displays."Hezekiah laughed, but there was affection in it. "I would love nothing better than to visit there. But I'm afraid I'd be tempted to loot the place, and carry it all away with me.”

“Mazer, i don't want to keep dreaming these things. I'm afraid to sleep. I keep thinking of things i don't want to remember. My whole life keeps playing out as if i were a recorder and someone else wanted to watch the most terrible parts of my life”
