Why We See Things and Not the Holes Between Them. We can now attempt an answer to the question why we do so. Two of the factors of organization which we have so far discussed seem to me to be the most important causes of this effect.

Look at any landscape photograph. You see the shape of the things, the mountains, and trees and buildings, but not of the sky.
