“Memory is a barricade against forgetting; light is a bulwark against darkness; life is a flex against the stillness of the grave. Maybe that's what I'm trying to do here, clear a space in all the debris, through all the anxieties and worries, where I can just exist, easily and simply, entire, for as long as I have left.”

“Don't worry. They're all against me. But I have one advantage: they don't know what they want. I do.”

“Science is a way to call the bluff of those who only pretend to knowledge. It is a bulwark against mysticism, against superstition, against religion misapplied to where it has no business being.”

“There is nothing like suspense and anxiety for barricading a human's mind against the Enemy. He wants men to be concerned with what they do; our business is to keep them thinking about what will happen to them.”

“Claim your space. Draw a circle of light around it. Push back against the dark. Don't just survive. Celebrate.”

“When the universe is ephemeral, one can easily feel that human existence is meaningless. Why should I do anything at all?On the other hand it is tempting to try and make the best of it. I'm here, anyway. The imagination won't cope if I try to picture where I'd otherwise be.”
