“If there is a god, he is not only a wizard at leaving clues behind. More than anything, he's a master of concealment. And the world is not something that gives itself away. The heavens still keep their secrets. There is little gossip amongst the stars. But no one has forgotten the Big Bang yet. Since then, silence has reigned supreme, and every thing there is moving away. One can still come across a moon. Or a comet. Just don't expect friendly greetings. No visiting cards are printed in space.”

“When we gaze at a star in the Milky Way which is 50,000 light-years away from our sun, we are looking back 50,000 years in time.""The idea is much too big for my little head.""The only way we can look out into space, then, is to look back in time. We can never know what the universe is like now. We only know what it was like then. When we look up at a star that is thousands of light-years away, we are really traveling thousands of years back in the history of space.”

“let's say you and a small child go to a magic show, where things are made to float in the air. Which of you would have the most fun?""I probably would.""And why would that be?""Because I would know how impossible it all is.""So... for the child it's no fun to see the laws of nature being defied before it has learned what they are.""I guess that's right.""And we are still at the crux of Hume's philosophy of experience. He would have added that the child has not yet become a slave of the expectations of habit; he is thus the more open-minded of you two. I wonder if the child is not also the greater philosopher? He comes utterly without preconceived opinions. And that, my dear Sophie, is the philosopher's most distinguishing virtue. The child perceives the world as it is, without putting more into things than he experiences”

“If just one of [those people] experiences life as a crazy adventure--and I mean that he, or she, experiences this every single day... Then he or she is a joker in a pack of cards.”

“Watching Limelight with my mother really brought home to me the brevity of life. I realized in a little while that I would die and leave everything behind. Unlike vain people, I had the ability to think this right through. I had no difficulty in picturing full theatres and cinemas long after myself was gone. Not everybody can do that. Many are so intoxicated with sensual impressions that they're not able to grasp that there is a world out there. And therefore they're not able to comprehend the opposite either - they don't understand that one day the world will end. We, however, are only a few missing heartbeats away from being divorced from humanity forever.”

“Hume emphasized that the expectation of one thing following another does not lie in the things themselves, but in our mind. And expectation, as we have seen, is associated with habit. Going back to the child again, it would not have stared in amazement if when one billiard ball struck the other, both had remained perfectly motionless. When we speak of the 'laws of nature' or of 'cause and effect,' we are actually speaking of what we expect, rather than what is 'reasonable.' The laws of nature are neither reasonable nor unreasonable, they simply are. The expectation that the white billiard ball will move when it is struck by the black billiard ball is therefore not innate. We are not born with a set of expectations as to what the world is like or how things in the world behave. The world is like it is, and it's something we get to know”

“Life is short for those who are truly able to understand that one day the entire world will come to a complete end. Not everyone is capable of that. Not everyone has the ability to comprehend what going away for all eternity really implies. There are too many distractions, hour by hour, minute by minute, to hinder such an understanding.”
