A Wrinkle in Time
How we cite our quotes:
"We look not at the things which are what you would call seen, but at the things which are not seen. For the things which are seen are temporal. But the things which are not seen are eternal." (11.85)
This sets up a hierarchy – the unseen is more important than the seen, more worthy of the beasts' time, because it doesn't exist in time. It's funny that the beast still uses the verb "look" to describe what they do – the metaphor of seeing as knowing comes in even as the physical act of seeing is denied.
