From Xenocide by Orson Scott Card:

So you’re saying that no one is ever individually intelligent, and groups are even stupider than individuals — and yet by keeping so many fools engaged in pretending to be intelligent, they still come up with some of the same results that an intelligent speices would come up with.

Exactly.

If they’re so stupid and we’re so intelligent, why do we have only one hive, which thrives here because a human being carried us? And why have you been so utterly dependent on them for every technical and scientific advance you make?

Maybe intelligence isn’t all it’s cracked up to be.

Maybe we’re the fools, for thinking we know things. Maybe humans are the only ones who deal with the fact that nothing can ever be known at all.
