PASSAGE ICuriosity is as clear and definite as any of our urges. We wonder what is in a sealed telegram or in a letter which someone else is absorbed or what is being said in the telephone booth or in low conversation. This inquisitiveness is vastly stimulated by jealousy suspicion, or any hint that we ourselves are directly or indirectly involved in. But there appears to be a fair amount of personal interest in other people’s affairs even when they do not concern us except as a mystery to be unravelled or a tale to be told. The reports of a divorce suit will have ‘news value’ for many weeks. They constitute a story like a novel, a play or a moving picture. This is not an example of pure curiosity. However, since readily, identify ourselves with others’ their joys and despair then become our own concern.
