“The reason is simple: people in an honor world automatically regard those who meet its codes with respect and those who breach them with contempt. Because these responses are automatic, the system is, in effect, extremely cheap to maintain. It only requires us to respond in ways we are naturally inclined to respond anyway… all of us are its guards.
“honor is needed, first because all other forms of enforcement of the rules requires surveillance. If we are to be able to pay you your bonus or punish you for your offenses, someone has to be able to find out what you have done. But when the battle is hardest, everything is obscured by the fog of the war. If we aim of a soldier were just to get his bonus or escape the brig, he would not have incentives to behave well at the very moment we most require it… honor, which is grounded in the individual soldiers own sense of honor (and that of his or her peers) can be effective without extensive surveillance… and anyone who… belongs to the honor world will be an effective enforcer of it, so that the cost of enforcement of honor is actually quite low… Especially when we require from the members of the group that share a honor code to take risks that are supererogatory (desirable but not requestable), money (financial incentives) is not the appropriate language, we give them the respect we know they deserve… It takes a sense of honor to feel implicated by the acts of others
