This publication will be devoted to the phenomenology of aggressiveness from the point of view of psychoanalysis. S. Freud, as the “Father of Psychoanalysis,” considered a person’s aggressive aspirations to be an independent instinctive predisposition, i.e. gave aggressiveness biological justifications that were originally inherent in the human program. The source of aggressiveness is Thanatos - a destructive drive of instinctive nature (the drive to death). But, at the same time, the component of aggression is embedded in the libidinal drives that are part of Eros, the source of life. Those. Thanatos and Eros are sources of aggressive beginnings that are directly opposite in nature: aggressive drives form part of the death drive and at the same time serve the libido included in the life instinct. The energy of Thanatos indirectly contributes to the release of aggression outward, towards other people and objects, so as not to be directed at oneself (one's body). If aggression does not find a way out, it can lead to psychosomatic illnesses (see the Chicago Seven) and even tragic consequences (suicide). In any case, aggression will sooner or later find a way out (here we are talking about exits to the outside), a positive way out - creativity, or motivation for activity, or a destructive way out: using the example of sadism. Containment of aggressive impulses can be carried out thanks to the mechanism of identifying oneself with the society in which a person lives and more often this is associated with the fear of punishment (of the authorities) and through internal control - the Super Ego (our internal moral code, received by us at the phallic stage (from 3 up to 6 years) development thanks to parents, usually the father, since the father is the bearer of prohibitions). The formation of aggressive impulses occurs at all stages of a child’s development and if fixation occurs at any of the stages of early development, then this can lead to the formation of aggressive character traits: - when fixating at the oral stage (from 0 to 1; 1, 5 years) we can observe at a more mature age sarcasm, a tendency to ridicule others and rude discussions of others; - when fixed at the anal stage of development (second year of life - 3 years) serves to form stubbornness, which tends to turn into stubbornness, and subsequently to which may be accompanied by vindictiveness and anger; - when fixated at the phallic stage (from 3 to 6 years) - subsequently: a demonstration of boasting, arrogance and lust for power. Aggression is also compared with the degree of communication activity, since it is necessary to ensure a person’s ability to establish contacts with other people; Aggression is also a general activity potential for solving issues of adaptation and maintaining one’s identity; it also contributes to the process of forming and maintaining goals. Let's look at an illustrative example: more often than not, children are ready to “fight” for their toy if someone else is trying to take it away from him (her), at this moment the child demonstrates an aggressive impulse that helps him defend the right to his toy (with the help of aggression personal development occurs, when a child learns from childhood to defend his rights and achieve goals, then in adulthood it will be much easier for him to achieve social preferences for himself). In the case when a child easily releases his toys when someone else needs them, we regard this as an alarming signal, since this is a projection of demonstrating similar behavior in the future, and here we are talking about deficit aggression, i.e. about an early prohibition of a child from realizing existing potential activity (usually from parental figures). Subsequently, we can observe difficulties in establishing interpersonal contacts, avoiding conflicts, competition; conformity, sacrificing one’s interests. Aggression contributes to the development of a child’s autonomy and his separation/individuation from parental figures in early development. A threat to.
