Bones, Season 5

Brennan:
You have faith that you will retain your faith? Why?

Booth:
Because, Bones. The sun will come up and tomorrow's a new day.

Brennan:
I know that feeling.

Booth:
Really?

Brennan:
Mm-hmm.

Booth:
You know what it feels like to get your faith back?

Brennan:
When I see effects and I am unable to discern a cause, my faith in reason and consequences is shaken.

Booth:
Then what happens?

Brennan:
Two plus two equals four. I put sugar in my coffee and it tastes sweet. The sun comes up because the world turns. These things are beautiful to me. There are mysteries I will never understand, but everywhere I look I see proof that for every effect there is a corresponding cause. Even if I can't see it. I find that reassuring.

Booth:
And life is good again.

Brennan:
Life is very good.

Booth:
Yes, it is.
