Sigmund Freud, the father of psychoanalysis, used to say that most of us have a personality that looks very much like an onion: In the center you have the Id, a very simple component that all it wants is immediate gratification and self-Pleasure thus following the … Pleasure Principle. Built around the Id, there is a second entity called the Ego, which basically is a system that helps the Id to find and acquire all those pleasures it requires by adapting its needs to the reality of our world (Reality Principle). Around those two you have the Super Ego which consists of all the programming society has given to us and thus following … the Morality Principle.
