According to Sigmund Freud, the complete adoption of moral standards that a society prescribes is practically unattainable.
Due to the instinctive, impulsive side of human nature, man only partially adopts these norms, especially those which are forbidden by certain behaviors.
According to Freud, personality is made up of three structures: the id (the center of urge and unconscious impulses), the super-ego (responsible for conscience and moral thinking) and the ego ( the center of consciousness, mediate between instincts and principles imposed by culture and morality).
The relationship between them is not static, but very lively, changeable, dynamic.
