Sigmund Freud's ego model in psychology has 3 parts. The first of three parts is ego of course which is the more organized part of someones personality structure. Sigmund stated that ego attempts to mediate between ID and reality. Basically stated is our ego helps us realize what is real. ID is the unorganized part of personality and basically tries to avoid painful and unhappy situations. According to Sigmund a baby would be a perfect example of being only ID because it survives purely from using its instincts. Sigmund Freud the went on to explain super ego. Which was our ego mixed with our conscious brain when put together makes us try to achieve that perfection that everybody want to hit in something. The super ego works against our ID in that the super ego wants social reputation or manners while the ID just wants whatever instant gratification or instinctual aspect it wants/needs. In all it is up to the ego to keep each one in check and indulge equally in each of these 2 types.
