Quote #16
There was a gasp, a murmur of astonishment and horror; a young girl screamed; standing on a chair to get a better view some one upset two test-tubes full of spermatozoa. Bloated, sagging, and among those firm youthful bodies, those undistorted faces, a strange and terrifying monster of middle-agedness, Linda advanced into the room, coquettishly smiling her broken and discoloured smile, and rolling as she walked, with what was meant to be a voluptuous undulation, her enormous haunches. Bernard walked beside her. (10.17)
John and Linda have power in the new world because of their individuality. In this case, Linda, in her natural, aged state, can effect change in the way these pre-conditioned citizens never could.
Quote #17
Mustapha Mond's anger gave place almost at once to mirth. The idea of this creature solemnly lecturing him—him—about the social order was really too grotesque. The man must have gone mad. "I ought to give him a lesson," he said to himself; then threw back his head and laughed aloud. For the moment, at any rate, the lesson would not be given. (11.36)
Mustapha is an incredibly interesting character because of the way he handles his own power. He knows he's above Bernard, but doesn't need to prove it. This is basically the opposite of Bernard himself, who, insecure with his power, has to exercise it constantly.
Quote #18
"A New Theory of Biology" was the title of the paper which Mustapha Mond had just finished reading. He sat for some time, meditatively frowning, then picked up his pen and wrote across the title-page: "The author's mathematical treatment of the conception of purpose is novel and highly ingenious, but heretical and, so far as the present social order is concerned, dangerous and potentially subversive. Not to be published." He underlined the words. "The author will be kept under supervision. His transference to the Marine Biological Station of St. Helena may become necessary." A pity, he thought, as he signed his name. It was a masterly piece of work. But once you began admitting explanations in terms of purpose—well, you didn't know what the result might be. It was the sort of idea that might easily decondition the more unsettled minds among the higher castes—make them lose their faith in happiness as the Sovereign Good and take to believing, instead, that the goal was somewhere beyond, somewhere outside the present human sphere, that the purpose of life was not the maintenance of well-being, but some intensification and refining of consciousness, some enlargement of knowledge. Which was, the Controller reflected, quite possibly true. But not, in the present circumstance, admissible. He picked up his pen again, and under the words "Not to be published" drew a second line, thicker and blacker than the first; then sighed, "What fun it would be," he thought, "if one didn't have to think about happiness!" (12.39)
The Controllers may have gained their power by manipulating science, but they can only keep it by curbing the same sort of technological advances that got them to their current positions.
