Freud arrives at his conclusions about the super-ego by combining the idea of internalization with the idea of the Oedipus complex. In early childhood, prior to the Oedipus complex, an individual forms an important identification with the father. This identification is later complicated by the object-cathexis that forms as a result of the mother's breast. The attitude toward the father then becomes ambivalent, for the paternal figure is simultaneously identified with yet perceived as an obstacle. Later, the entire dual-natured complex is taken internally, forming a new part of his ego which has the same moral authority that a parent might have. This seems simple enough, but if the super-ego manifests itself as a father figure, then we cannot ignore the dual nature of the Oedipal father. The super-ego compels the ego to be like the father (as in the primary identification) and simultaneously places an injunction upon the ego, compelling it not to be like the father (as in the Oedipus complex, where the male child cannot take the father's place.)
