The general claim that the mind is not monolithic or homogenous continues to have an enormous influence on people outside of psychology.
Freud believed the energy used to run the ego (such as to dissolve reality, moral and neurotic anxiety) was derived from the Id in the form of cathexis and from the Superego in the form of anticathexis.
This idea of a "male ego" conflicts with the known facts of the ego, superego and id, yet has nevertheless been accepted into unofficial lore.
The thoughts that were foremost when Ego State A was executive fade into relative unawareness, experienced only dimly on the borders of consciousness, to be replaced by new thoughts relating to the relationship with her friend and the potential experience of the party.
To speak of inner ego boundaries means no more than the fact that the ego senses itself, not only as an indiscriminant whole, but also as having a thousand different `shades' of feeling, depending on which aspect or state or sector of the ego comes uppermost in influencing the others.
Ego states are separated internally from the unconscious by a boundary, and externally from the environment by another boundary.
