In Victor Hugo's "Les Misérables," the quote highlights how significant dangers and challenges reveal the bonds between people who may not know each other. It suggests that in times of crisis, individuals often come together, transcending their differences to support one another. This sense of unity showcases the hidden connections that exist in society, even among strangers.

The idea underscores the transformative power of adversity, as it can foster compassion and solidarity. When faced with great peril, people may set aside their individual concerns and reach out to help others, showcasing a fundamental human instinct for empathy and cooperation. Through these moments, the shared humanity of people becomes apparent, breaking down barriers and emphasizing the importance of community.
