zt ego

In modern English, ego has many meanings. It could mean one’s self-esteem, an inflated sense of self-worth, or in philosophical terms, one’s self. However, according to Freud, the ego is the part of the mind that contains the consciousness. Originally, Freud used the word ego to mean a sense of self, but later revised it to mean a set of psychic functions such as judgment, tolerance, reality-testing, control, planning, defense, synthesis of information, intellectual functioning, and memory.
In a diagram of the Structural and Topographical Models of Mind, the ego is depicted to be half in the consciousness, while a quarter is in the preconscious and the other quarter lies in the unconscious.
When the ego is personified, it is like a slave to three harsh masters: the id, the super-ego, and the external world. It has to do its best to suit all three, thus is constantly feeling hemmed by the danger of causing discontent on two other sides. It is said, however, that the ego seems to be more loyal to the id, preferring to gloss over the finer details of reality to minimize conflicts while pretending to have a regard for reality. But the super-ego is constantly watching every one of the ego's moves and punishes it with feelings of guilt, anxiety, and inferiority. To overcome this the ego employs defense mechanisms.The defense mechanisms are not done so directly or consciously. They lessen the tension by covering up our impulses that are threatening.
Denial, displacement, intellectualisation, fantasy, compensation, projection, rationalisation, reaction formation, regression, repression, and sublimation were the defense mechanisms Freud identified. However, his daughter Anna Freud clarified and identified the concepts of undoing, suppression, dissociation, idealisation, identification, introjection, inversion, somatisation, splitting, and substitution.
