In this chapter, the author presents a story where a man's little daughter had taken upon herself her mother's duties. She identified herself with her mother. She played the role of mother exactly as she had for years seen it played at home, though, in secret, she had disapproved of her mother's conduct. This identification nullified her own personality and replaced it with another. This is a phenomenon that takes the most surprising forms among the victims of hysteria. But it would be erroneous to think that it occurs only among hysterics. Almost all persons, especially women, succumb to the seductive power of identification. The most beautiful instance of identification is furnished by love. One who is in love has completely identified himself with the beloved. A delusion is frequently only a wholly successful identification in the interests of the desire to escape from painful realities.
