Marie-Louise von Franz believed fairytales to be the purest and simplest expressions of the collective unconscious. Too often the interpreter regresses to a personalized approach, however, heroes and heroines are abstractions that embody collective archetypes. The innumerable variations within the same fairytale told in different cultures are like a musical theme crisscrossing humanity. In Volume 8, von Franz establishes that there is only one psychic fact to which the fairytale addresses itself, namely, the SELF.
