But if the bear is of limited rationality, having a capacity for making rational and consistent choices among the alternatives that he perceives but lacking the capacity to solve games—that is, lacking the capacity to determine introspectively the choices that a partner would make—the communication system must make it possible for him to receive a message from his partner. The partner must then formulate the proposition (choice) for the bear and communicate it to him, in order that the bear may then respond by accepting the promise (now that he sees what the “solution” is) and transmitting authoritative evidence back to his own partner.
