Smallville, Season 4

Lionel:
You have a ferocious desire to find all the answers, son, but don't let your search for those stones turn into your personal Tower of Babel.

Lex:
I'm not trying to get closer to God, Dad. I'm trying to solve the riddles He's laid out for me.

Lionel:
Did you ever think there might be a reason why we weren't given the answers?

Lex:
To challenge us?

Lionel:
Or maybe to humble us. Knowledge comes from finding the answers, yes, but understanding what the answers mean is what brings wisdom. Men who didn't understand the difference have been the ruin of some of the world's greatest civilizations.

Lex:
Is that why you stopped looking for the stones? Because you're afraid?

Lionel:
No. No, I stopped because I realized that even if I find the three stones, I'm not gonna find what I'm really looking for. Neither will you.
