Some of the most famous psychologists of the past left a profound mark on the history of science and had a major influence on the development of psychology as a discipline. One of the greatest is considered to be the founder of psychoanalysis, Sigmund Freud (1856–1939). He developed the theory of psychoanalysis, which focuses on unconscious processes that shape human behavior. He proposed a model of the psyche divided into three parts: "Id," "Ego," and "Superego." He also introduced the concepts of the Oedipus complex, sublimation, and defense mechanisms.

Thus, Sigmund Freud proposed one of the best-known models of the psyche, consisting of three parts: "Id", "Ego" and "Superego". Each of these parts plays its own role in a person’s mental life, and their interaction shapes behavior, thoughts, and emotions. Here is a brief description of each part:

1. "Id"

Description: The "Id" is the most primitive and instinctive part of the psyche. It is entirely unconscious and contains basic desires and drives such as the pursuit of pleasure, aggression, sexual instincts, hunger, and other biological needs.

Operating principle: The "Id" operates according to the pleasure principle — it seeks immediate satisfaction of its desires and does not take reality, morality, or consequences into account.

Example: When a person wants to satisfy hunger or thirst immediately without thinking about where or how to do so, this is an expression of the "Id" at work.

2. "Ego"

Description: The "Ego" is the part of the psyche that is aware of reality and acts in accordance with it. Its main function is to find a balance between the demands of the "Id," the moral standards of the "Superego," and the constraints of the outside world.

Operating principle: The "Ego" operates according to the reality principle. It tries to satisfy the desires of the "Id," but does so in a way that avoids negative consequences and takes social norms into account.

Example: When a person feels hungry, the "Ego" may decide to wait for an appropriate moment to eat in a suitable place instead of acting impulsively.

3. "Superego"

Description: The "Superego" represents the set of moral norms, ethical beliefs, and social rules that a person internalizes during upbringing. It acts as an inner judge, comparing actions and desires with moral standards.

Operating principle: The "Superego" operates according to the principle of morality and ideals. It strives for perfection and controls behavior, producing feelings of guilt or pride depending on how closely a person’s actions correspond to their moral beliefs.

Example: If a person feels guilty about wanting to deceive someone or break the rules, this is the "Superego" at work, condemning such actions.

Conflict: Conflict often arises between these three components. For example, the "Id" demands immediate satisfaction of desires, the "Superego" may condemn these desires as immoral, and the "Ego" has to find a compromise between them while taking reality into account.

Defense mechanisms: To cope with conflicts between the "Id," "Ego," and "Superego," the "Ego" uses various defense mechanisms such as repression, sublimation, projection, and rationalization. This helps reduce inner stress and anxiety.

Freud believed that a person’s mental health depends on the balance among these three structures. If one part dominates or the conflict becomes too intense, this can lead to neuroses and other psychological problems.

Concepts developed by Sigmund Freud, such as the Oedipus complex, sublimation, and defense mechanisms, are an important part of his psychoanalytic theory. These ideas are intended to explain mental processes, unconscious desires, and how a person copes with inner conflicts and social constraints.

Oedipus complex — a key concept in Freud’s psychoanalysis referring to a child’s unconscious sexual attraction to the opposite-sex parent and rivalry with the same-sex parent. According to Freud, this occurs during the phallic stage of psychosexual development, when the child becomes aware of the genitals and sex differences. Freud named the complex after the ancient Greek myth of Oedipus, who unknowingly killed his father and married his mother.

A. Stages of the Oedipus complex

• Attachment to the opposite-sex parent: During the phallic stage (approximately from ages 3 to 6), the child begins to experience an unconscious attraction to the opposite-sex parent. Boys may unconsciously wish to displace the father in order to take his place in the relationship with the mother.
• Rivalry with the same-sex parent: The child perceives the same-sex parent as a rival for the love and attention of the opposite-sex parent.
• Castration anxiety: According to Freud, boys begin to recognize the father’s strength and authority and fear that he may punish them by "castrating" them for their attraction to the mother.
• Resolution of the complex: Successful resolution of the Oedipus complex occurs when the child gives up sexual desires toward the opposite-sex parent and identifies with the same-sex parent. This leads to the formation of the "Superego" — an internal moral standard that helps control the impulses of the "Id."

B. The Oedipus complex in girls (Electra complex)

Freud also believed that girls have a similar complex, which was called the Electra complex (the term was later introduced by Carl Jung). Girls experience disappointment over the absence of a penis, which Freud called "penis envy," and may unconsciously feel attraction to the father while identifying with the mother.

C. Consequences of an unresolved Oedipus complex

Freud believed that if a child does not resolve the conflict at this stage, it can lead to psychological problems later in life, such as neuroses, identity difficulties, and problems in interpersonal relationships.

Sublimation — one of the most important defense mechanisms proposed by Freud. It consists of transforming strong, often unconscious, sexual or aggressive impulses into socially acceptable actions or creative activity.

A. The process of sublimation

Sublimation allows a person to use the energy of the "Id" (instinctive, biological drives) to achieve goals approved by society. Unlike repression, in which impulses are simply pushed into the unconscious, sublimation redirects these impulses toward constructive and productive goals.

B. Examples of sublimation

Artistic or creative expression: A person may transform sexual or aggressive drives into artistic creativity. For example, an artist or writer may use inner conflicts to create works of art.

Scientific achievement: Freud believed that many great scientific discoveries may also result from sublimation — when energy directed toward satisfying personal impulses is transformed into a passion for research and knowledge.

Social activity: Aggressive impulses may be sublimated into athletic achievement or a professional career.

C. The importance of sublimation for mental health

Sublimation is considered one of the most mature and healthy defense mechanisms because it allows a person to transform inner conflicts into productive activity instead of trying to suppress or avoid them.

Defense mechanisms are unconscious strategies used by the "Ego" to protect against anxiety and inner conflict arising between the "Id," "Ego," and "Superego." These mechanisms help reduce anxiety caused by unresolved conflicts or unwanted impulses. Freud and his daughter Anna Freud identified several major defense mechanisms.

Major defense mechanisms

• Repression

Repression is the process by which unpleasant or anxiety-provoking thoughts, desires, or memories are pushed out of consciousness into the unconscious. A person who has experienced a traumatic event may not remember the details because they have been repressed into the unconscious, yet the event may still influence their behavior.

• Denial

Denial is the refusal to acknowledge the reality of a particular situation or fact that causes stress or anxiety. A person may deny the fact of a serious illness, refusing to acknowledge the diagnosis or symptoms.

• Projection

Projection involves attributing one’s own unwanted feelings, thoughts, or impulses to other people. A person who feels aggression toward someone may claim that it is actually the other person who is aggressive toward them.

• Rationalization

Rationalization is the creation of logical and acceptable explanations for behavior that is actually caused by less acceptable motives. A person who fails an exam may claim that the exam was too difficult instead of admitting that they did not prepare enough.

• Regression

Regression is a return to an earlier and less mature stage of development in response to stress or anxiety. An adult may behave like a child when faced with a serious problem, for example by becoming capricious or seeking protection from their parents.

• Sublimation

As already mentioned, sublimation is the transformation of instinctive drives into socially acceptable forms of behavior.

• Reaction formation

This defense mechanism involves expressing feelings opposite to those a person actually experiences in order to suppress their true impulses. A person who feels hostility toward someone may display excessive politeness and friendliness toward that person.

• Identification

Identification is the process by which a person unconsciously adopts another person’s traits or behavior in order to reduce anxiety or feel more confident. A teenager may begin imitating a popular classmate in order to adapt better to the group.

Conclusion

Freud developed concepts that explain how people cope with inner conflicts and regulate unconscious impulses. The Oedipus complex explains the role of early childhood experience in personality development, sublimation allows strong instinctive desires to be transformed into socially useful actions, and defense mechanisms help a person avoid anxiety caused by inner conflicts. These ideas had an enormous influence on psychoanalysis and on later generations of psychologists and psychotherapists.
