Here's why:
* Suppressing Individuality: The World State is built on the principle of mass production and conformity. Reference books, with their focus on factual information and objective knowledge, could potentially lead individuals to question the established order, develop independent thought, and challenge the social structures.
* Control of History: The World State has a carefully crafted history, one that conveniently ignores any inconvenient truths or challenges to their current system. Historical books that provide different perspectives or challenge the official narrative are seen as subversive and are therefore prohibited.
* Promoting Consumerism: The World State's economy is driven by consumption and the pursuit of pleasure. Literature that promotes reflection, introspection, or philosophical inquiry is seen as a distraction from the pursuit of material happiness and hedonistic pursuits.
* Eliminating Emotional Complexity: Literature and art often explore complex emotions, existential questions, and social injustices. The World State seeks to eliminate these complexities by providing a simplified, controlled environment that prioritizes emotional stability and social harmony over deep thinking.
In short, the libraries of the World State are deliberately curated to reinforce the social order and prevent individuals from questioning their place in the world or seeking knowledge that might challenge their pre-determined roles.
