These classes, in order from highest to lowest, are Alpha, Beta, Gamma, Delta, and Epsilon. Embryos destined for the higher classes get chemicals to perfect them both physically and mentally, whereas those of the lower classes are altered to be imperfect in those respects. The embryos, which exist within tubes and incubators, are provided with differing amounts of chemicals and hormones in order to condition them into predetermined classes. The reader is then introduced to the class system of this world, where citizens are sorted as embryos to be of a certain class. Huxley begins the novel by thoroughly explaining the scientific and compartmentalized nature of this society, beginning at the Central London Hatchery and Conditioning Centre, where children are created outside the womb and cloned in order to increase the population. In this society, emotions and individuality are conditioned out of children at a young age, and there are no lasting relationships because 'every one belongs to every one else' (a common World State dictum). The novel examines a futuristic society, called the World State, that revolves around science and efficiency. The book heavily influenced George Orwell's 1984 and science-fiction in general.

Borrowing from The Tempest, Huxley imagines a genetically-engineered future where life is pain-free but meaningless. Brave New World is Aldous Huxley's dystopian novel.
