“Everybody is so terribly sensitive about the things they know best.”

“So many things are possible as long as you don't know they're impossible.”

“So many things are possible just as long as you don't know they're impossible.”

“And, as you've discovered, so many things are possible just as long as you don't know they're impossible.”

“But that can never be," said Milo, jumping to his feet."Don't be too sure," said the child patiently, "for one of the nicest things about mathematics, or anything else you might care to learn, is that many of the things which can never be, often are. You see," he went on, "it's very much like your trying to reach Infinity.

“Outside the window, there was so much to see, and hear, and touch — walks to take, hills to climb, caterpillars to watch as they strolled through the garden.

It's learning what to do with what you learn and learning why you learn things at all that matters.""That's just what I mean," explained Milo as Tock and the exhausted bug drifted quietly off to sleep. "Many of the things I'm supposed to know seem so useless that I can't see the purpose in learning them at all.""You may not see it now," said the Princess of Pure Reason, looking knowingly at Milo's puzzled face, "but whatever we learn has a purpose and whatever we do affects everything and everyone else, if even in the tiniest way.”
