Myths? I know to some that is a dirty word, especially if it is being said about something that they believe in.
I'm sure many here have seen that Internet movie call Zeitgeist about all the similarities in the Jesus myth and other myths, what accounts for this sharing of themes found in myths all over the world? Even in peoples that are very remote from one another?
Carl Jung who studied and understood a great deal about the unconscious part of our psyche, became very interested in myths,, because he came to realized that Myths are a projection of the unconscious part of man's psyche,,and therefore they tell us a great deal about the unconscious part of our psyche by means of these projections.
The similarity in Myth structure is mainly because Humans all share the same "collective unconscious".
