In Victor Hugo's "Les Miserables," the notion of civil war raises profound questions about the nature of conflict and human relationships. The quote reflects a deep philosophical inquiry into what defines a war; it suggests that every battle, even those considered civil, ultimately involves individuals who are fundamentally connected—often as brothers or fellow citizens. This perspective emphasizes the tragic irony of people turning against each other in conflict.

Moreover, the statement challenges the concept of foreign wars, implying that all wars are intrinsically tied to human bonds. Since they are fought by people with shared histories, emotions, and ties, the lines between enemy and ally blur. Hugo’s exploration evokes a sense of shared humanity, urging the reader to consider the painful implications of conflict and the importance of solidarity among individuals, even in times of strife.
