In a private conversation with Bernard, Helmholtz, and John, Mustapha Mond comments on the dangers of real science and mentions that he was once a pretty good physicist in his time. Mustapha Mond also mentions that his experiments were unorthodox and threatened the stability of the World State, which is why he was almost sent to an island. Mond explains that science can be a public danger; the government authorities recognize that intellectual thought and independence can undo every stable pillar of their society. Fortunately for Mustapha Mond, he was given the choice of training to become a World Controller or being banished on an island with other exiles. Mustapha Mond tells Helmholtz that he preferred to become a World Controller and genuinely enjoys the struggle to create a completely happy, comfortable society, where people are conditioned to reject truth and beauty.
