A novel painting a dark picture of the future, in which all people are grown in jars, manipulated physically and chemically in vitrio (i can't exactly say "in vivo" here) to adjust intelligence and tolerance to extreme environments, and through classical conditioning and hypnopaedia after decantation to implant the government-designed morality. Everyone is made to be happy with their lot in life and consumer culture, and all are given the drug soma to be self-administered whenever unpleasant reality intrudes. But without the freedom to be unhappy or have any choice in life, do they really live?

The protagonists attempt to challenge this order, which brings out the whole point of the book. Read it, it's good

Although 1984 is more popular, Brave New World seems to be closer to our actual future...
