Huxley is satirizing the society of the Brave new world by calling it something that is opposite by the virtue of satire
Step-by-step explanation:
In the passage given here John is urging people at the hospital to not take their potions as they will prove to be poison and make them not ask for their freedom.
This was something that happened in the chapter when he encounters a group he had previously seen and one of them that is simply referred to as savage keeps repeating ' Brave new world'.
It is a satire that betrays any possibility of any hope for the people in the world and the following lines only stay to convey the same with all the Romantic talk of finding something fine and noble.
