The Ego and the Id (The Standard Edition of the Complete Psychological Works of Sigmund Freud) by Sigmund Freud Quotes

“The ego ideal is therefore the heir of the Oedipus complex, and thus it is also the expression of the most powerful impulses and the most important libidinal vicissitudes of the id.”
― Sigmund Freud, The Ego and the Id (The Standard Edition of the Complete Psychological Works of Sigmund Freud) by Sigmund Freud

“When it happens that a person has to give up a sexual object, there quite often ensues an alteration of his ego which can only be described as a setting up of the object inside the ego, as it occurs in melancholia; the exact nature of this substitution is as yet unknown to us...At any rate the process, especially in the early phases of development, is a very frequent one, and it makes it possible to suppose that the character of the ego is a precipitate of abandoned object-cathexes and that it contains the history of those object-choices....One gets the impression that the simple Oedipus complex is by no means its commonest form, but rather represents a simplification or schematization...Closer study usually discloses the more complete Oedipus complex to be both positive and negative, and is due to the bisexuality originally present in children: that is to say, a boy has not merely an ambivalent attitude towards his father and an affectionate object-choice towards his mother, but at the same time he behaves like a girl and displays an affectionate feminine attitude to his father and a corresponding jealousy and hostility towards his mother.”
