“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”

“So now you must choose... Are you a child who has not yet become world-weary? Or are you a philosopher who will vow never to become so? To children, the world and everything in it is new, something that gives rise to astonishment. It is not like that for adults. Most adults accept the world as a matter of course. This is precisely where philosophers are a notable exception. A philosopher never gets quite used to the world. To him or her, the world continues to seem a bit unreasonable - bewildering, even enigmatic. Philosophers and small children thus have an important faculty in common. The only thing we require to be good philosophers is the faculty of wonder…”

“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”

“There exists a world. In terms of probability this borders on the impossible. It would have been far more likely if, by chance, there was nothing at all. Then, at least, no one would have began asking why there was nothing.”

“I have gone around observing your activities from the outside. Because of this I have also been able to see things to which you have been blind... Every morning you have gone to work, but you have never been fully awake. Of course, you have seen the sun and the moon, the stars in the sky, and everything that moves, but you haven't really seen it at all. It is different for the Joker, because he was put into this world with a flaw: He sees too clearly and too much.”

“The individual in modern urban society had become `the public`, he said [Kierkegaard], and the predominant characteristic of the crowd, or the masses, was all their noncommittal `talk`. Today we would probably use the word `conformity`; that is when everybody `thinks` and `believes in` the same things without having any deeper feeling about it.”

“Sophie left the den and wandered about in the large garden. She tried to forget what she had learned at school, especially in science classes.If she had grown up in this garden without knowing anything at all about nature, how would she feel about the spring?Would she try to invent some kind of explanation for why it suddenly started to rain one day? Would she work out some fantasy to explain where the snow went and why the sun rose in the morning?”
