Here's how it's achieved:
* Clinical Language: The narrator uses precise, scientific terminology to describe the process of human creation and conditioning. This creates a sense of distance and objectivity, as if the process is purely technical and devoid of emotion.
* Emphasis on Efficiency and Control: The language emphasizes the speed and efficiency of the hatchery and conditioning process. This reinforces the sense of the world as a machine, where human life is managed and controlled for maximum productivity.
* Lack of Emotion: The narrator's tone is devoid of judgment or emotional response. This contributes to the feeling of detachment and the sense that the reader is observing a strange, almost alien world.
* Humorous Undertones: There are moments of dry humor, particularly in the descriptions of the conditioning processes and the students' reactions. This humor adds a layer of irony and subtly criticizes the society's values.
Overall, the tone of Chapter 2 sets the stage for the rest of the novel, establishing the world of Brave New World as a place where human individuality and freedom are sacrificed for the sake of stability and control. The detached, clinical tone highlights the dehumanizing aspects of this society and allows the reader to critically examine the consequences of such a system.
