“I don't understand it any more than you do, but one thing I've learned is that you don't have to understand things for them to be.”

“If you don't understand something, break it apart; reduce it to its components. Since they are simpler than the whole, you have a much better chance of understanding them; and when you have succeeded in doing that, put the whole thing back together again.”

“I've been learning to live without you now
But I miss you sometimes
The more I know, the less I understand
All the things I thought I knew, I'm learning them again.”

“I guess I don't really understand you yet,' I said. 'I'm not all that smart. It takes me a while to understand things. But if I do have time, I will come to understand you -- better than anyone else in the world ever can.”

“I don't always understand poetry!'

'You don't always understand it? Timms, I never understand it. But learn it now, know it now and you will understand it… whenever.”

“I don't understand you. You don't understand me. What else do we have in common?”

“One thing I've learned in all these years is not to make love when you really don't feel it; there's probably nothing worse you can do to yourself than that.”

“Young man, in mathematics you don't understand things. You just get used to them.”

“You have to do stuff that average people don't understand because those are the only good things.”

“… you realize that you don't understand yourself any better than you understand anyone else.”
