A wealth of information creates a poverty of attention, as Herbert Simon said. When attention is scarce, secrets can be hidden. Dialogues from G. K. Chesterton’s The Sign of the Broken Sword illustrate this vividly.
Father Brown: Where does a wise man hide a pebble?
Flambeau: On the beach.
Father Brown: Where does a wise man hide a leaf?
Flambeau: In the forest.
Father Brown: What does he do if there is no forest?
Flambeau: What does he do?
Father Brown: He grows a forest to hide it in. A fearful sin.
Flambeau did not answer.
Father Brown: And if he wished to hide a dead leaf, he would make a dead forest. And if a man had to hide a dead body, he would make a field of dead bodies to hide it.
