"Air travel reminds us who we are. It's the means by which we recognize ourselves as modern. The process removes us from the world and sets us apart from each other. We wander in the ambient noise, checking one more time for the flight coupon, the boarding pass, the visa. The process convinces us that at any moment we may have to submit to the force that is implied in all this, the unknown authority behind it, behind the categories, the languages we don't understand. This vast terminal has been erected to examine souls."
