Electra complex classical psychoanalytic theory, the child's identification with the same-sex parent is the successful resolution of the Electra complex and of the Oedipus complex; his and her key psychological experience to developing a mature sexual role and identity. Sigmund Freud instead proposed that girls and boys resolved their complexes differently—she via penis envy, he via castration anxiety; and that unsuccessful resolutions might lead to neurosis. Hence, women and men who are fixated in the Electra and Oedipal stages of their psychosexual development might be considered "father-fixated" and "mother-fixated". As a psychoanalytic term for daughter–mother psychosexual conflict, the Electra complex derives from
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.
