In describing the various origins of Freud's formulations of the Oedipus complex, we first traced the entire development of his concept of the Oedipus complex. Next, we pointed out the opposition to Freud's theory, placing special emphasis on the revisions and modifications advocated by Jones, and the views of the major female analysts during the years following the introduction of the structural theory. Finally, we described the status of the Oedipus complex at the time of Freud's death.
