Final answer:
Freud postulated that personality arises from the tension between our innate drives (id) and societal constraints (superego), regulated by the ego operating on the reality principle.
Step-by-step explanation:
According to Sigmund Freud, an individual's personality is created due to the conflict between fulfilling biological aggressive and pleasure-seeking drives and the problems generated from social internalized controls over these drives. Freud's psychodynamic theory of personality explains that our personality develops through the efforts to balance the demands of the id, ego, and superego. The id operates on the pleasure principle, seeking immediate gratification of these drives. The superego develops as a child interacts with the social environment, internalizing the moral and ethical codes of society. Lastly, the ego operates on the reality principle, mediating between the id and the superego by facilitating actions that satisfy id's desires in a socially appropriate and realistic way.
