The Fear of Loss of Love
The original source of this inherent fear needs but little description, because it obviously grew out of man’s polygamous habit of stealing his fellow man’s mate, and his habit of taking liberties with her whenever he could.
Jealousy, and other similar forms of dementia praecox grow out of man’s inherited fear of the loss of love of someone. This fear is the most painful of all the six basic fears. It probably plays more havoc with the body and mind than any of the other basic fears, as it often leads to permanent insanity.
The fear of the loss of love probably dates back to the stone age, when men stole women by brute force. They continue to steal females, but their technique has changed. Instead of force, they now use persuasion, the promise of pretty clothes, motor cars, and other “bait” much more effective than physical force. Man’s habits are the same as they were at the dawn of civilization, but he expresses them differently.
Careful analysis has shown that women are more susceptible to this fear than men. This fact is easily explained. Women have learned, from experience, that men are polygamous by nature, that they are not to be trusted in the hands of rivals.
