"The theme of a Brave New World is not the advancement of science as such; it is the advancement of science as it affects human individuals" how does the novel full fill Huxleys theme

I think that one of Huxley's major themes is the limitations of science, espevially at the cost of humanity. While society has mainly banned art and religion rather than science, Mustapha Mond also claims that too much scientific progress can also reduce the ultimate happiness of each individual. Science, he tells the reader, is responsible for a great many of the achievements of their society and for the levels of happiness that each individual achieves. Nevertheless, if scientific progress occurs without restraint, it will lead to less happiness.

For instance, the government does not engineer food in a scientific laboratory, even though it would be faster and would feed more people. By farming food naturally, the government gives more work for the lower caste people to do and thus keeps them occupied and happy. This example shows that progress does not always maximize happiness, a fact that John the Savage clearly sees in his new society.
