The quote from Victor Hugo’s "Les Miserables" highlights the enduring quality of innocence and purity, likening them to a precious pearl that remains unsullied despite the surrounding filth. This metaphor emphasizes that true innocence is resilient and steadfast, unaffected by the negativity or challenges that may try to obscure it.

Furthermore, the imagery of pearls remaining intact while being surrounded by manure suggests that beauty and purity can emerge from even the harshest circumstances. It reflects on the idea that although life may present difficult or unpleasant experiences, one's inherent goodness can shine brightly, much like stars amid the darkness.
