Electra complex of "Mother" develops the super-ego as the girl establishes a discrete sexual identity (ego). Without a penis, the girl cannot sexually possess her mother, as the infantile id demands. Consequently, the girl redirects her desire for sexual union upon her father, and thus progresses to heterosexual femininity, which culminates in bearing a child who replaces the absent penis. Moreover, after the phallic stage, the girl’s psychosexual development includes transferring her primary erogenous zone from the infantile clitoris to the adult vagina. Freud thus considered the feminine Oedipus attitude ("Electra complex") to be more emotionally intense than the Oedipal conflict of
Oedipus Rex ability, as seen in "Oedipus at Colonus". It is deliberately ironic that the "seer" can "see" better than Oedipus, despite being blind. In one line (Oedipus the king, 469), Tiresias says: ""So, you mock my blindness? Let me tell you this. You [Oedipus] with your precious eyes, you're blind to the corruption of your life ..."" (Robert Fagles 1984) Sigmund Freud in "Interpretation of Dreams" wrote a notable passage regarding of the destiny of Oedipus as well as the Oedipus complex. He analyzes why this play, "Oedipus Rex", written in Ancient Greece, is so effective even to a modern audience.
