Aldous Leonard Huxley’s Brave New World is the first novel that takes human cloning as a theme and it is with no doubt the most advanced thought experiment in 1932. Based on the theories of ethical literary criticism, this paper takes this dystopian novel as an example to analyze how the utopian culture in this new world overturns traditional ethics and moral principles, and the allegory of consumer society and politics is achieved. By using human cloning techniques, the controller in the book creates a utopia with “community, identity, and stability” and controls people’s emotion even though the human cloning is dissolving the moral fabric of society. This novel warns readers that when the development of technology violates ethics and morality, the alienation of reason and technology would be on the road to ruin for human beings.
