Final answer:
The social science theorist pleased by the use of the term "unrestrained id" would be Sigmund Freud, who theorized that the id is the primitive and instinctual part of the psyche that operates on the pleasure principle, seeking immediate gratification.
Step-by-step explanation:
The term "unrestrained id" is derived from the theories of Sigmund Freud, a significant figure in the field of psychology and psychoanalysis. Freud theorized that the human psyche is divided into three parts: the id, ego, and superego. The id represents the instinctual, primitive components of personality, including basic drives such as hunger and sexuality, and operates based on the pleasure principle, seeking immediate gratification of its desires. An unrestrained id would refer to a situation where these instinctual drives are expressed freely without the moderating influence of the ego and the moral considerations of the superego.
The idea of an unrestrained id aligns with Freud's belief that the unconscious mind harbors desires and impulses that are usually held in check by other parts of the psyche and societal norms. When someone makes a comment without restraint, it could be seen as a manifestation of the id breaking through those controls. Freud's theories emphasize the complexity and often subterranean nature of human behavior, arguing that humans are not entirely rational beings and that their actions may be driven by unconscious desires and conflicts.
