In Victor Hugo's "Les Miserables," the author suggests that the terms 'happy' and 'unhappy' are often too simplistic for thoughtful individuals. He implies that true happiness is elusive and not easily defined by mere labels. The complexities of human experience go beyond these binary classifications, leading to a deeper exploration of life’s struggles and joys.

Hugo further indicates that our world serves as a temporary space, or a 'vestibule,' leading to a deeper existence beyond our current experiences. In this view, no one achieves genuine happiness, underscoring a universal sense of longing and dissatisfaction that threads through human life. This perspective invites readers to reflect on the nature of happiness and the pursuit of a more meaningful existence.
