Public Opinion 1.1.3.6

The only feeling that anyone can have about an event he does not experience is the feeling aroused by his mental image of that event. That is why until we know what others think they know, we cannot truly understand their acts. I have seen a young girl, brought up in a Pennsylvania mining town, plunged suddenly from entire cheerfulness into a paroxysm of grief when a gust of wind cracked the kitchen window-pane. For hours she was inconsolable, and to me incomprehensible. But when she was able to talk, it transpired that if a window-pane broke it meant that a close relative had died. She was, therefore, mourning for her father, who had frightened her into running away from home. The father was, of course, quite thoroughly alive as a telegraphic inquiry soon proved. But until the telegram came, the cracked glass was an authentic message to that girl. Why it was authentic only a prolonged investigation by a skilled psychiatrist could show. But even the most casual observer could see that the girl, enormously upset by her family troubles, had hallucinated a complete fiction out of one external fact, a remembered superstition, and a turmoil of remorse, and fear and love for her father.
