In Aldous Huxley's novel "Brave New World," being sent to an island is a form of exile or isolation for individuals who do not conform to the society's norms or rules. These individuals are removed from the mainstream society and placed in secluded areas such as islands to prevent them from influencing or disrupting the established order.
Mustapha Mond, one of the World Controllers in the novel, was almost sent to an island because of his nonconformity and unorthodox ideas. Despite holding a position of power within the World State, Mustapha Mond entertained forbidden thoughts and engaged in activities that challenged the status quo. His subversive behavior and questioning of societal norms made him a candidate for exile to an island as a means of containment and control by the ruling regime.
