There are many themes in this book. Most of them deal with the morality of certain issues and if this could be an acceptable way of life. It also gives an example of how nothing can ever be perfect.
The first theme is the idea of community, identity, and stability. This is the motto of the World State. It is achieved by organizing life so that a person is almost never alone. Identity is in large part the result of genetic engineering. It is also achieved by teaching everyone to conform, so that someone who has or feels more than a minimum of individuality is made to feel like an outcast. Stability is the other goal and is the reason for designing the society this way. Stability is the minimizing of conflict, risk, and change.
The second theme is that science is a means of control. This book shows how human individuals are affected by the advancement of science. It bases its worries on the dangers of the possible misuse of biology, physiology, and psychology to achieve community, identity, and stability. Ironically, at the end of the book, it is seen that the World State is complete control over human actibity destroys even the scientific progress that gained it such control.
The third theme is the threat of genetic engineering. The book shows what could happen if genetic engineering advances and is used to control the world. The book describes genetic engineering as how the new world breeds a prescribed number of humans artifically for specific qualities.
The fourth these is the misuse of psychological conditioning. Every human being in the new world is conditioned to fit society's needs. Biologically speaking, the citizens are conditioned to their specific jobs by adding chemicals or spinning the bottles thy grow in. After the citizens leave the bottles, they are psychologically conditioned, mainly by hynopaedia. They are brainwashed through every stage of their development.
The fifth theme is the destruction of the family. The combination of genetic engineering, bottle-birth, and sexual promiscuity means that thereis no monogamy, marriage, or family. "Mother" and "father" are obscene words that may be used scientifically on rare, carefully chosen occasion to label ancient sources of psychological problems.
The last theme is the oppression of individual differences. some characters in A Brave New World difffer from the normal. These members include Bernard, Helmholtz, John the Savage, and even Mustapha Mond. In each case the differences are crushed. Bernard and Helmholtz are exiled, John commits suicide, and Mond stifles his own individuality by giving up his power as Controller.
