Brave New World, Chapter 8 - 'Information Memorization'

"What are chemical? he would ask. Oh, stuff like magnesium salts, and alcohol for keeping the Deltas and Epsilons small and backward, and calcium carbonate for bones, and all that sort of thing. But how do you make chemicals, Linda? Where do they come from? Well, I don't know.You get them out of bottles. And when the bottles are empty, you send up to the Chemical Store for more. It's the Chemical Store people who make them, I suppose. Or else they send to the factory for them. I don't know, I never did any chemistry. My job was always with the embryos" (Huxley 130).

In arguing on both sides of how scientific and technological advancement benefits humanity is demonstrated when John asks his mother Linda, some questions he had after reading the she gave him to improve his reading which was on the conditioning of embryos. But since Linda had grown up in the brave new world could not give John any straight answers, she only answered him with only the things she knew from the job she had as a Beta in the Fertilizing Room. The positive effects of only knowing the information that was sleep taught to you for you needed to know for your future job is that when someone becomes of the age to start working they would not have to look at multiple different positions to apply for to get a job, they would automatically have a job waiting for them because of the information thy already know for that position. The negative effects to this is that when someone asked them questions about there job like John did with Linda asking about where chemicals come from, that person would most unlikely be able to answer it correctly because they only know the information that was sleep taught to them for the potential jobs they would go on to do.
