David Foster Wallace:

I never, even for a moment, doubted what they'd told me. This is why it is that adults and even parents can, unwittingly, be cruel: they cannot imagine doubt's complete absence. They have forgotten.

Paul Graham:

Adults lie constantly to kids. I'm not saying we should stop, but I think we should at least examine which lies we tell and why.

Decius:

I've gotten old enough that I now understand why adults seek to escape reality. Paradoxically, I think I was better at escaping reality when I was younger.

Michael Chabon:

The thing that strikes me now when I think about the Wilderness of Childhood is the incredible degree of freedom my parents gave me to adventure there.

Mark C. Taylor:

Belief not tempered by doubt poses a mortal danger.

"Doubt":

Father Brendan Flynn: You haven't the slightest proof of anything!
Sister Aloysius Beauvier: But I have my certainty!

Decius:

It's important to understand that it isn't Congress that must change -- it is us.
