An ancient parable tells of a group of blind men that were given the task of defining an elephant by touch alone. The first grasped only the foot and stated that an elephant was like a pillar. The second clutched the tail and declared that an elephant was like a piece of rope. The third felt the trunk and suggested that an elephant was like a waterspout. The parable reveals how easy it is to miss the totality of an object when we examine it from our limited subjective viewpoint.
The concept of the Ego is akin to the elephant. Since its introduction into popular culture at the turn of the 19th century the concept of the Ego has expanded to include a multitude of definitions, each depending on the definer’s point of view.
