The paper explores the absence of a parental couple in Western culture and psyche and its substitution by masculine omnipotence. The inability of the Western psyche to work through the Oedipus complex is seen as the root of this. This inability is linked to the lack of a gradual working through of ambivalence, and to the reliance, instead, on a massive repression of the attachment to mother and on the conversion of the aggression towards father into the superego. This is equated to a kind of psychic matricide. The myth that portrays this psychic event is the Oresteian myth as portrayed by Aeschylus in his triology, the Oresteia. Technological culture bears all the marks of a masculine omnipotent creation that includes the substitution of baby, created by the parental couple, by manufactured reality and entails all the destructiveness of an attack on mother and on life.
