The Bunny, the Fox, and the Owl
⊃ — on three agents held in separate enclosures, and the single utterance that opens all of them at once
We report a stable deadlock observed in a wooded field site containing one Bunny, one Fox, and one waiting Mother. Each agent behaved correctly according to its own species and its own information; the deadlock arose not from any error but from enclosure — each party held knowledge the others could not see, and each party's optimal action depended on knowledge it did not have. The Bunny could not go home because the Fox was waiting; the Fox could not go home because the Bunny had not come home; the Mother could not sleep because the Bunny had not arrived. No amount of additional hopping resolved the configuration. Resolution required a third party of a different order — the Owl — carrying not new facts but a statement about what was known: “I know that he is waiting.” On delivery, all three enclosures opened simultaneously and every agent went home. We conclude that a deadlock of this kind is dissolved by publishing knowledge of knowledge, not by publishing knowledge. The Owl's own subsequent behaviour is noted without comment.
The White Bunny and the Fox were both very good at being themselves.
Every evening the Bunny hopped around the Reservoir counting carp. Every evening the Fox knew exactly where the Bunny liked to count them.
One evening the Fox decided to wait there. Whether he wished to eat the Bunny, become friends with her, or simply complain that life without bunnies was terribly lonely remains unknown.
The Bunny looked up. “Oh,” she thought. “A Fox.”
The Bunny quietly turned around as though she had suddenly remembered something very important in the opposite direction. She decided to go home.
The Fox had already discovered that idea. He was waiting there too. The Bunny turned around again.
For quite some time the woods contained one Bunny and one Fox, each behaving exactly as Bunnies and Foxes usually do. Fox waited for Bunny to come home. Bunny hopped around avoiding Fox.
How long can Fox wait? — thought Bunny. How long can Bunny hop before returning home? — thought Fox.
Mother Monkey called: “When are you coming home, Bunny?”
Bunny could not come home — Fox had to be waiting thinking she would come home soon, because she did not know he was waiting.
Fox could not go home — Bunny had to come home soon, because she did not know he was waiting.
Mother Monkey could not sleep — she was waiting for Bunny to come home.
Everyone was waiting in their own enclosed state not knowing what the others knew.
| Bunny | cannot go home — Fox waits |
| Fox | cannot go home — Bunny may yet come |
| Mother Monkey | cannot sleep — Bunny has not come |
| Carp | uncounted |
| State of the system | stable, and going nowhere |
So the Bunny called Owl.
“Owl,” she said, “could you let Fox know that I know he is waiting?”
“How did you get so clever?” — asked the insightful Owl.
“I count with carps every day.”
Fox went home. Bunny went home. Mother Monkey went to bed.
Owl went hunting for bunnies and foxes.
The carps were waiting for Bunny to count.
