Famous quotes containing the word rarity:
“Television hangs on the questionable theory that whatever happens anywhere should be sensed everywhere. If everyone is going to be able to see everything, in the long run all sights may lose whatever rarity value they once possessed, and it may well turn out that people, being able to see and hear practically everything, will be specially interested in almost nothing.”
