Oedipus complex desire (libido) for mother, and aggression towards father, student–collaborator Carl Jung counter-proposed that girls experienced desire for father and aggression towards mother via the Electra complex—derived from the 5th-century BC Greek mythologic character Electra, who plotted matricidal revenge with Orestes, her brother, against Clytemnestra, their mother, and Aegisthus, their stepfather, for their murder of Agamemnon, her father (cf. "Electra", by Sophocles). Moreover, because it is native to Freudian psychology, orthodox Jungian psychology uses the term "Oedipus complex" only to denote a boy's psychosexual development. In classical Freudian psychology the super-ego, "the heir to the Oedipus complex", is formed as the
Oedipus complex difference; the other main character in the Oedipal drama becomes Tiresias (the false hypothesis erected against anxiety about a new theory)". Resultantly, "Bion regarded the central crime of Oedipus as his insistence on knowing the truth at all costs". From the postmodern perspective, Jacques Lacan argued against removing the Oedipus complex from the center of psychosexual developmental experience. He considered "the Oedipus complex—in so far as we continue to recognize it as covering the whole field of our experience with its signification ... [that] superimposes the kingdom of culture" upon the person, marking his or her introduction to symbolic order.
