In Victor Hugo's "Les Miserables," the profound statement that the sun would perish without love underscores the essential role of affection in human existence. Love serves as a source of light and warmth, much like the sun, illuminating lives and fostering connection. Without this force, the vibrancy and joy of life would fade, leading to emotional and spiritual desolation.

The metaphor also suggests that love is fundamental to our survival and happiness. It emphasizes the idea that relationships and compassion are vital for a fulfilling life, imparting meaning and purpose. In a world devoid of love, the essence of humanity would diminish, reflecting Hugo's deep belief in the transformative power of love and its necessity for a thriving society.
