Did you now that…..
Heinz Hartmann (1894-19729), the American psychiatrist, defines the EGO as the substratum of the personality ?
Hartmann defines the Ego in terms of its function, especially the control of the apparatus of motility and perception (internal and external), the contact with reality, and the inhibition of primary instinctual drives.
This definition of Hartmann implies, besides the genetic, the adaptive point of view-namely, the mediating function of the ego between present reality and needs of other psychic systems.
