 There's no reason why I shouldn't tell you. If anyone truly understands the nature of fear, is able accurately to forecast the actions and reactions of an individual, then he can use fear as a weapon. Society will react as the individual reacts. You see, society doesn't want to believe that anything can menace it, doesn't want to take action to protect itself any more than the individual does. This was something that Hitler and Mussolini understood intuitively.
