“Give me the positions and velocities of all the particles in the universe, and I will predict the future.”

“People ask me to predict the future, when all I want to do is prevent it. Better yet, build it. Predicting the future is much too easy, anyway. You look at the people around you, the street you stand on, the visible air you breathe, and predict more of the same. To hell with more. I want better.”

“We race toward the future at the velocity of the present.”

“Morality—like velocity—is relative. The determination of it depends on what the objects around you are doing. All one can do is measure one's position in relation to them; never can one measure one's velocity or morality in terms of absolutes.”

“I was not predicting the future, I was trying to prevent it.”

“Listen,” he said gently and stepped closer. “No one can predict the future, but right now you’re the most important thing to me. I would regret it for the rest of my life if we didn’t give this a chance.”
