Quote 4
"I wonder if you'd like to come back to London with us?" he asked, making the first move in a campaign whose strategy he had been secretly elaborating ever since, in the little house, he had realized who the "father" of this young savage must be. (8.77)
Bernard takes a role similar to the World State here—his power lies in his ability to manipulate.
Quote 5
"He's mad," whispered Bernard, staring with wide open eyes. "They'll kill him. They'll…" A great shout suddenly went up from the mob; a wave of movement drove it menacingly towards the Savage. "Ford help him!" said Bernard, and averted his eyes.
"Ford helps those who help themselves." And with a laugh, actually a laugh of exultation, Helmholtz Watson pushed his way through the crowd. (15.39-40)
We're thinking that Helmholtz laughs here because, in all likelihood, he's probably the guy who wrote the phrase "Ford helps those who helps themselves." And if not, at least we see that he's laughing at the absurdity of his own profession—the writing of inane hypnopaedic phrases.
Quote 6
"…what would it be like if I could, if I were free—not enslaved by my conditioning."
"But, Bernard, you're saying the most awful things."
"Don't you wish you were free, Lenina?"
"I don't know what you mean. I am free. Free to have the most wonderful time. Everybody's happy nowadays."
He laughed, "Yes, 'Everybody's happy nowadays.' We begin giving the children that at five. But wouldn't you like to be free to be happy in some other way, Lenina? In your own way, for example; not in everybody else's way."
"I don't know what you mean," she repeated. (6.1.27-32)
Lenina and Bernard can't understand each other here because they have different conceptions of the word "free." For Bernard, freedom is the freedom to be unhappy. Of course, Bernard isn't yet able to express this, so it is left to John to find the words in the second half of the novel. For Lenina, freedom is just another adjective she's been taught to apply to her life as it stands. She is free and happy because she's been told she is free and happy. The language has been corrupted and is as controlled by the State as citizens are.
