Id, Ego and Superego
by Saul McLeod published 2008
Perhaps Freud's single most enduring and important idea was that the human psyche has more than one aspect. Freud (1923) saw the psyche structured into three parts (i.e. tripartite), the id, ego and superego, all developing at different stages in our lives.
These are systems, not parts of the brain, or in any way physical.
The id (or it)
The id consists of all the inherited (i.e. biological) components of personality, including the sex (life) instinct Eros (which contains the libido), and aggressive (death) instinct - Thanatos.
The id is the impulsive (and unconscious) part of our psyche which responds directly and immediately to the instincts. The personality of the newborn child is all id and only later does it develop ego and super-ego.
The id demands immediate satisfaction and when this happens we experience pleasure, when it is denied we experience ‘unpleasure’ or pain. The id is not affected by reality, logic or the everyday world.
On the contrary, it operates on the pleasure principle (Freud, 1920) which is the idea that every wishful impulse should be satisfied immediately, regardless of the consequences.
The Ego (or I)
Initially the ego is “that part of the id which has been modified by the direct influence of the external world” (Freud 1923). The ego develops in order to mediate between the unrealistic id and the external real world.
Ideally the ego works by reason whereas the id is chaotic and totally unreasonable. The ego operates according to the reality principle, working our realistic ways of satisfying the id’s demands, often compromising or postponing satisfaction.
Like the id, the ego seeks pleasure and avoids pain but unlike the id the ego is concerned with devising a realistic strategy to obtain pleasure. Freud made the analogy of the id being the horse while the ego is the rider.
Often the ego is weak relative to the head-strong id and the best the ego can do is stay on, pointing the id in the right direction and claiming some credit at the end as if the action were its own. The ego has no concept of right or wrong; something is good simply if it achieves its end of satisfying without causing harm to itself or to the id.
The Superego (or above I)
The superego incorporates the values and morals of society which are learned from one's parents and others. It develops around the age of 4 5 during the phallic stage of psychosexual development.
The superego's function is to control the id's impulses, especially those which society forbids, such as sex and aggression. It also has the function of persuading the ego to turn to moralistic goals rather than simply realistic ones and to strive for perfection.
The superego consists of two systems: The conscience and the ideal self. The conscience can punish the ego through causing feelings of guilt. For example, if the ego gives in to id demands, the superego may make the person feel bad though guilt.
The ideal self (or ego-ideal) is an imaginary picture of how you ought to be, and represents career aspirations, how to treat other people, and how to behavior as a member of society.
Behavior which falls short of the ideal self may be punished by the superego through guilt. The super-ego can also reward us through the ideal self when we behave ‘properly’ by making us feel proud.
If a person’s ideal self is too high a standard, then whatever the person does will represent failure. The ideal self and conscience are largely determined in childhood from parental values and you were brought up.
