Final answer:
John is called 'the Savage' primarily to emphasize his outsider status in the society he encounters, highlighting both the cultural contrast and his role as a challenger of accepted norms.
Step-by-step explanation:
The term "Savage" is used to emphasize John's outsider status in Aldous Huxley's Brave New World.
The reason behind calling John "the Savage" seems to be a literary device used by the author to depict the contrast between John's upbringing in the more primitive "Savage Reservation" and the technologically advanced but emotionally and culturally sterile society he encounters. The label "Savage" underscores the cultural and moral differences and highlights the effects of societal conditioning, as John is essentially a mirror that reflects the deficiencies and the potential hypocrisy of the "civilized" society. Moreover, John's character challenges the socially accepted norms of the society he enters, thereby reinforcing his role as an outsider and provocateur.
