Id, ego and super-ego
The id, ego, and super-ego are a set of three concepts in psychoanalytic theory describing distinct, interacting agents in the psychic apparatus (defined in Sigmund Freud's structural model of the psyche). The three agents are theoretical constructs that describe the activities and interactions of the mental life of a person. In the ego psychology model of the psyche, the id is the set of uncoordinated instinctual desires; the super-ego plays the critical and moralizing role; and the ego is the organized, realistic agent that mediates between the instinctual desires  of the id and the critical super-ego; Freud explained that: The functional importance of the ego is manifested in the fact that, normally, control over the approaches to motility devolves upon it. Thus, in its relation to the id, [the ego] is like a man on horseback, who has to hold in check the superior strength of the horse; with this difference, that the rider tries to do so with his own strength, while the ego uses borrowed forces. The analogy may be carried a little further. Often, a rider, if he is not to be parted  from his horse, is obliged to guide [the horse] where it wants to go; so, in the same way, the ego is in the habit of transforming the id's will into action, as if it were its own. The existence of the super-ego is observable in how people can view themselves as guilty and bad, shameful and weak, and feel compelled to do certain things. In "The Ego and the Id" (1923), Freud presents "the general character of harshness and cruelty exhibited by the [ego] ideal — its dictatorial "Thou shalt""; thus, in the psychology of the  ego, Freud hypothesized different levels of ego ideal or superego development with greater ideals: The earlier in the child's development, the greater the estimate of parental power; thus, when the child is in rivalry with the parental imago, the child then feels the dictatorial "Thou shalt", which is the manifest power that the imago represents on four levels: (i) the auto-erotic, (ii) the narcissistic, (iii) the anal, and (iv) the phallic. Those different levels of mental development, and their relations to parental imagos, correspond to specific id forms of aggression and affection; thus aggressive and destructive desires  animate the myths in the fantasies and repressions of patients, in all cultures. In response to the unstructured ambiguity and conflicting uses of the term "the unconscious mind", Freud introduced the structured model of ego psychology (id, ego, super-ego) in the essay "Beyond the Pleasure Principle" (1920) and elaborated, refined, and made that model formal in the essay "The Ego and the Id". Psychic apparatus. Id. The id is the instinctual component of personality that is present at birth, and is the source of bodily needs and wants, emotional impulses and desires, especially aggression and the  libido (sex drive). The id acts according to the pleasure principle — the psychic force oriented to immediate gratification of impulse and desire — defined by the avoidance of pain. Freud said that the Id is unconscious, by definition: In the id: Developmentally, the id precedes the ego; the psychic apparatus begins, at birth, as an undifferentiated id, part of which then develops into a structured ego. While "id" is in search of pleasure, "ego" emphasizes the principle of reality. Thus the id: The mind of a newborn child is regarded as completely "id-ridden , in the sense that it is a mass of instinctive drives and impulses, and needs immediate satisfaction. The id" moves on to what organism needs. Example is reduction of tension which is experienced. The id "knows no judgements of value: no good and evil, no morality. ...Instinctual cathexes seeking discharge—that, in our view, is all there is in the id." It is regarded as "the great reservoir of libido", the instinctive drive to create—the life instincts that are crucial to pleasurable survival. Alongside the life instincts came the death instincts—the death drive which Freud  articulated relatively late in his career in "the hypothesis of a "death instinct", the task of which is to lead organic life back into the inanimate state." For Freud, "the death instinct would thus seem to express itself—though probably only in part—as an "instinct of destruction" directed against the external world and other organisms" through aggression. Freud considered that "the id, the whole person...originally includes all the instinctual impulses...the destructive instinct as well", as eros or the life instincts. Ego. The ego (Latin for "I", ) acts according to the reality principle; i.e., it seeks to  please the id's drive in realistic ways that, in the long term, bring benefit, rather than grief. At the same time, Freud concedes that as the ego "attempts to mediate between id and reality, it is often obliged to cloak the (unconscious) commands of the id with its own preconscious rationalizations, to conceal the id's conflicts with reality, to profess...to be taking notice of reality even when the id has remained rigid and unyielding." The reality principle that operates the ego is a regulating mechanism that enables the individual to delay gratifying  immediate needs and function effectively in the real world. An example would be to resist the urge to grab other people's belongings, but instead to purchase those items. The ego is the organized part of the personality structure that includes defensive, perceptual, intellectual-cognitive, and executive functions. Conscious awareness resides in the ego, although not all of the operations of the ego are conscious. Originally, Freud used the word ego to mean a sense of self, but later revised it to mean a set of psychic functions such as judgment, tolerance, reality testing, control, planning, defense, synthesis of information , intellectual functioning, and memory. The ego separates out what is real. It helps us to organize our thoughts and make sense of them and the world around us. "The ego is that part of the id which has been modified by the direct influence of the external world. ...The ego represents what may be called reason and common sense, in contrast to the id, which contains the passions...in its relation to the id it is like a tug of war, which the ego has to hold in check the id to not let it loose ; with the difference, that the teams fought against one other in equality, while the ego was against the much stronger 'id'." Still worse, "it serves three severe masters...the external world, the super-ego and the id." Its task is to find a balance between primitive drives and reality while satisfying the id and super-ego. Its main concern is with the individual's safety and allows some of the id's desires to be expressed, but only when consequences of these actions are marginal. "Thus the ego, driven by the id, confined by the  super-ego, repulsed by reality, struggles...[in] bringing about harmony among the forces and influences working in and upon it," and readily "breaks out in anxiety—realistic anxiety regarding the external world, moral anxiety regarding the super-ego, and neurotic anxiety regarding the strength of the passions in the id." It has to do its best to suit all three, thus is constantly feeling hemmed by the danger of causing discontent on two other sides. It is said, however, that the ego seems to be more loyal to the id, preferring to gloss over the finer details of  reality to minimize conflicts while pretending to have a regard for reality. But the super-ego is constantly watching every one of the ego's moves and punishes it with feelings of guilt, anxiety, and inferiority. To overcome this the ego employs defense mechanisms. The defense mechanisms are not done so directly or consciously. They lessen the tension by covering up our impulses that are threatening. Ego defense mechanisms are often used by the ego when id behavior conflicts with reality and either society's morals, norms, and taboos or the individual's expectations as a result of the  internalization of these morals, norms, and their taboos. Denial, displacement, intellectualisation, fantasy, compensation, projection, rationalization, reaction formation, regression, repression, and sublimation were the defense mechanisms Freud identified. However, his daughter Anna Freud clarified and identified the concepts of undoing, suppression, dissociation, idealization, identification, introjection, inversion, somatisation, splitting, and substitution. In a diagram of the , the ego is depicted to be half in the consciousness, while a quarter is in the preconscious and the other quarter lies in the unconscious. In modern English, ego has many meanings. It could mean one's self-esteem; an inflated sense of self-worth; the  conscious-thinking self; or in philosophical terms, one's self. Ego development is known as the development of multiple processes, cognitive function, defenses, and interpersonal skills or to early adolescence when ego processes are emerged. Super-ego. The super-ego () reflects the internalization of cultural rules, mainly taught by parents applying their guidance and influence. Freud developed his concept of the super-ego from an earlier combination of the ego ideal and the "special psychical agency which performs the task of seeing that narcissistic satisfaction from the ego ideal is ensured...what we call our 'conscience'." For him "the installation  of the super-ego can be described as a successful instance of identification with the parental agency," while as development proceeds "the super-ego also takes on the influence of those who have stepped into the place of parents — educators, teachers, people chosen as ideal models". The super-ego aims for perfection. It forms the organized part of the personality structure, mainly but not entirely unconscious, that includes the individual's ego ideals, spiritual goals, and the psychic agency (commonly called "conscience") that criticizes and prohibits their drives, fantasies, feelings, and actions. "The Super-ego can be thought of as  a type of conscience that punishes misbehavior with feelings of guilt. For example, for having extra-marital affairs." Taken in this sense, the super-ego is the precedent for the conceptualization of the inner critic as it appears in contemporary therapies such as IFS. The super-ego works in contradiction to the id. The super-ego strives to act in a socially appropriate manner, whereas the id just wants instant self-gratification. The super-ego controls our sense of right and wrong and guilt. It helps us fit into society by getting us to act in socially acceptable  ways. The super-ego's demands often oppose the id's, so the ego sometimes has a hard time in reconciling the two. Freud's theory implies that the super-ego is a symbolic internalisation of the father figure and cultural regulations. The super-ego tends to stand in opposition to the desires of the id because of their conflicting objectives, and its aggressiveness towards the ego. The super-ego acts as the conscience, maintaining our sense of morality and proscription from taboos. The super-ego and the ego are the product of two key factors: the state  of helplessness of the child and the Oedipus complex. Its formation takes place during the dissolution of the Oedipus complex and is formed by an identification with and internalisation of the father figure after the little boy cannot successfully hold the mother as a love-object out of fear of castration. Freud described the super-ego and its relationship to the father figure and Oedipus complex thus: The concept of super-ego and the Oedipus complex is subject to criticism for its perceived sexism. Women, who are considered to be already castrated, do not identify with the father, and  therefore, for Freud, "their super-ego is never so inexorable, so impersonal, so independent of its emotional origins as we require it to be in men...they are often more influenced in their judgements by feelings of affection or hostility." However, Freud went on to modify his position to the effect "that the majority of men are also far behind the masculine ideal and that all human individuals, as a result of their human identity, combine in themselves both masculine and feminine characteristics, otherwise known as human characteristics." Advantages of the structural model. Freud's earlier, topographical model of the  mind had divided the mind into the three elements of conscious, preconscious, and unconscious. The conscious contains events that we are aware of, preconscious is events that are in the process of becoming conscious, and unconscious include events that we are not aware of. At its heart was "the dialectic of unconscious traumatic memory versus consciousness...which soon became a conflict between System Ucs versus System Cs." With what Freud called the "disagreeable discovery that on the one hand (super-)ego and conscious and on the other hand repressed and unconscious are far from coinciding," Freud took the step in the  structural model to "no longer use the term 'unconscious' in the systematic sense," and to rename "the mental region that is foreign to the ego...[and] in future call it the 'id'." The partition of the psyche defined in the structural model is thus one that cuts across the topographical model's partition of "conscious vs. unconscious". "The new terminology which he introduced has a highly clarifying effect and so made further clinical advances possible." Its value lies in the increased degree of precision and diversification made possible: Although the id is unconscious by definition, the ego and  the super-ego are both partly conscious and partly unconscious. What is more, with this new model Freud achieved a more systematic classification of mental disorder than had been available previously: It is important to realise however, that "the three newly presented entities, the id, the ego and the superego, all had lengthy past histories (two of them under other names)"—the id as the systematic unconscious, the super-ego as conscience/ego ideal. Equally, Freud never abandoned the topographical division of conscious, preconscious, and unconscious, though as he noted ruefully "the three qualities of consciousness and the three  provinces of the mental apparatus do not fall together into three peaceful couples...we had no right to expect any such smooth arrangement." The iceberg metaphor is a commonly used visual metaphor when attempting to relate the ego, id and superego with the conscious and unconscious mind. In the iceberg metaphor the entire id and part of both the superego and the ego would be submerged in the underwater portion representing the unconscious mind. The remaining portions of the ego and superego would be displayed above water in the conscious mind area. Translation. The terms "id", "ego , and super-ego" are not Freud's own. They are latinisations by his translator James Strachey. Freud himself wrote of ""das Es"", ""das Ich"", and ""das Über-Ich""—respectively, "the It", "the I", and "the Over-I" (or "I above"); thus to the German reader, Freud's original terms are more or less self-explanatory. Freud borrowed the term ""das Es"" from Georg Groddeck, a German physician to whose unconventional ideas Freud was much attracted (Groddeck's translators render the term in English as "the It"). The word "ego" is taken directly from Latin, where it is the nominative of the  first person singular personal pronoun and is translated as "I myself" to express emphasis. Figures like Bruno Bettelheim have criticized the way "the English translations impeded students' efforts to gain a true understanding of Freud" by substituting the formalised language of the elaborated code for the quotidian immediacy of Freud's own language.
