In Victor Hugo's "Les Miserables," the quote emphasizes the transformative power of music and its role in social change. The ‘Carmagnole’ represents a song of the French Revolution that can incite rebellion against a tyrant like Louis XVI, suggesting that mere opposition to authority can lead to political turmoil. However, the 'Marseillaise' symbolizes a broader vision of liberation, suggesting that music can also inspire a collective struggle for freedom and justice around the world.

This contrast highlights the potential of anthems not just to incite immediate revolt, but to foster a larger, unifying cause. By connecting individual struggles to a global sense of liberation, Hugo proposes that the right message can empower people to aspire toward a more just and equitable society, transcending national borders. Ultimately, the quote captures the idea that music can be a catalyst for profound societal transformation.
