Carl Jung was a close compatriot of Freud for many years, and they developed a very strong relationship. A major theoretical disagreement between the two created a split in their relationship.  What caused their breakup?  What was their disagreements due to the conscious and unconscious theories?  What about Freud’s theory of emphasized sex and Jung’s disagreement? Does this historical perspective validate or invalidate the modern-day applicability of Neo-Freudian theories? Explain.
