In Milan Kundera's "The Unbearable Lightness of Being," the protagonist sees books as symbols of a hidden connection or fraternity among individuals. This perception suggests that people who cherish literature possess a certain sensitivity or depth that makes them less likely to engage in harmful behavior. Her belief embodies an idealistic view of book lovers as inherently good and trustworthy.

This notion creates a comforting sense of security for her, as she associates the presence of a library with a safeguard against potential harm. By placing such value on literature, she implies that those who take the time to read and appreciate books are more likely to understand and empathize with others, fostering a more supportive environment.
