You see this all depends on what theory in psychology you're referring to. The concept of the "Ego" means many different things in psychology. Freud thought that the ego was a part of the brain that correlates with the Id and the super ego. Personally, I believe in the theory Freud came up with of the three parts of the subconscious mind working efficiently as a unit. But i also believe that the ego is our perception of ourselves and can easily be confused and dressed up as something else, if you will.
“Whoever will be free must make himself free. Freedom is no fairy gift to fall into a man's lap. What is freedom? To have the will to be responsible for one's self.” - Max Stirner.
