In Victor Hugo's "Les Misérables," the quote emphasizes that the emotional capacity to love exists, but the circumstances can inhibit its expression. The characters often face societal and personal challenges that prevent them from forming meaningful connections, despite their desire to love. This theme highlights the struggle against external barriers that complicate human relationships.

The idea that love is possible yet hindered speaks to the broader human experience, where individuals may long for connection but are thwarted by their situations or the constraints of society. Hugo's narrative showcases the innate human yearning for love and the obstacles that can deter it, making the quest for genuine affection a pivotal aspect of the story.
