Understanding is the reward of faith. Therefore, seek not to understand that you may believe, but believe that you may understand.

I'm not interested to believe in something, but to understand the people who believe.

I believe that people believe what they believe they believe.

There are two different types of people in the world, those who want to know, and those who want to believe.

Most people like to believe something is or is not true. Great scientists tolerate ambiguity very well. They believe the theory enough to go ahead; they doubt it enough to notice the errors and faults so they can step forward and create the new replacement theory. If you believe too much you'll never notice the flaws; if you doubt too much you won't get started. It requires a lovely balance.

You can only find out what you actually believe (rather than what you think you believe) by watching how you act. You simply don’t know what you believe, before that. You are too complex to understand yourself.

Those who understand a thing are not equal to those who are fond of it, and those who are fond of it are not equal to those who delight in it.

Oh, I have a habit of letting myself be lectured on the things I know best. I like to see if they are understood in the same way I understand; for there are many ways of knowing the same thing

Delight at having understood a very abstract and obscure system leads most people to believe in the truth of what it demonstrates.

To believe is indeed to lose the understanding in order to gain God.

Those who truly understand their faiths understand the stories are metaphorical.

I would like to understand things better, but I don’t want to understand them perfectly.

Those who believe, believe everything, while those who doubt don't believe a thing.

Knowing it — knowing it's true is one thing, but believing what you know... well, there's the tough part.
