“An intelligent person may understand the logic of a bandit. The bandit’s actions follow a pattern of rationality: nasty rationality, if you like, but still rationality. You can foresee a bandit’s actions, his nasty maneuvers, and ugly aspirations, and often can build up your defenses. A stupid creature will harass you for no reason, for no advantage, without any plan or scheme and at the most improbable times and places. You have no rational way of telling if and when and how and why the stupid creature attacks. When confronted with a stupid individual you are completely at his mercy. The fact that the activity and movements of a stupid creature are absolutely erratic and irrational not only makes defense problematic but it also makes any counterattack extremely difficult—like trying to shoot at an object that is capable of the most improbable and unimaginable movements.”
