The New Wineskin
Brave New World, primarily because it more accurately reflects the modern world. While in
1984, Big Brother uses oppression and censorship to control and manipulate the peoples to His will,
Brave New World shows a world of distraction. The government mandates a stream of entertainment industry that overshadows the actions of the governments and political issues. Soon after, the want for entertainment will reduced the amount of people who genuinely sought out knowledge; this was helped by censorship of science, which was viewed as harmful to the State as it is the seeking of truth by its very nature.
The symbolism is more powerful, the writing is better (in my opinion), and the themes and events in the book more closely fit reality than 1984 do, even if both can very well occur in some sense or another.
when i was in a history of religious oppression class, one of the students came in startled. Her next door neighbor's door had been blasted in and destroyed, the students inside were raided and harassed... but they weren't the ones responsible. The real criminal - some kind of internet related crime or some similar, was in some other apartment. I cannot fully convey the horror these students experienced, but the campus was UC Davis, use your imagination.
This is one of many examples where I feel like 1984 more strongly fits the description people are experiencing. If I lived in the Bread Basket with my grandma and we watched Dr. Phil, and Dr. Oz, Then Brave New World would probably seem more applicable.
