Huxley wrote that the Brave New world is not science itself, but science as it affects people. There is rigid control of reproduction through technological and medical intervention. In controlling reproduction, they are able to control what everyone looks like and how they act. A long with this, they create entertainment machines that generate leisure as well as high levels of consumption and production that are the basis of stability. The difference between science and technology? The state uses science in order to build and better technology that ultimately creates a happy and superficial world.
