For entry here, each one paid in full with his or her memory: people deprived of their past, forgetting the existence of loved ones and friends, are seized by an ungrounded thirst for aggression. But whoever wants to remember more must be the most merciless killer—and is simply obligated to shoot first. Such is the law of survival in this world—the Frontier Law.
