“Thorne shrugged. "They're still just fantasies. They're not real. Have you ever seen a self-esteem? Can you bring me one on a plate? How about a photon? Can you bring me one of those?"
Kelly shook her head. "No, but. . ."
"And you never will, because those things don't exist. No matter how seriously people take them," Thorne said. "A hundred years from now, people will look back at us and laugh. They'll say, 'You know what people used to believe? They believed in photons and electrons. Can you imagine anything so silly?' They'll have a good laugh, because by then there will be newer and better fantasies." Thorne shook his head. "And meanwhile, you feel the way the boat moves? That's the sea. That's real. You smell the salt in the air? You feel the sunlight on your skin? That's all real. You see all of us together? That's real. Life is wonderful. It's a gift to be alive, to see the sun and breathe the air. And there isn't really anything else.”

“It isn't a matter of wanting it or not. It's a matter of what you think you can accomplish. When the hunter goes out in the rain forest to seek food for his family, does he expect co control nature? No. He imagines that nature is beyond him. Beyond his understanding. Beyond his control. Maybe he prays to nature, to the fertility of the forest that provides for him. He prays because he knows he doesn't control it. He's at the mercy of it.
But you decide you won't be at the mercy of nature. You decide you'll control nature, and from that moment on you're in deep trouble, because you can't do it -- and you never have -- and you never will. Don't confuse things. You can make a boat, but you can't make the ocean. You can make an airplane, but you can't make the air. Your powers are much less than your dreams of reason would have you believe.”

“Because the history of evolution is that life escapes all barriers. Life breaks free. Life expands to new territories. Painfully, perhaps even dangerously. But life finds a way.”

“I was stunned. I had only just met Stephen and for all his eccentricity I liked him. We both seemed shy in the presence of others, but were confident within ourselves. It was unthinkable that someone only a couple of years older than me should be facing the prospect of his own death. Mortality was not a concept that played any part in our existence. We were still young enough to be immortal.”
