In Victor Hugo's "Les Miserables," the quote reflects the paradox of finding joy in love despite the lack of completeness in life. Being blind symbolizes a lack of sight, which may signify ignorance of the harsh realities surrounding a person. However, it also suggests a pure experience of love untainted by the complexities and imperfections of the world.
This unique form of happiness indicates that love can transcend obstacles and deliver profound contentment even in the face of life's inadequacies. Hugo captures a deep emotional truth about the nature of happiness, suggesting that true fulfillment often comes from love, regardless of one's circumstances.
