In Victor Hugo's "Les Miserables," a profound observation is made about the nature of innocence. The narrative expresses that within every person lies a precious quality, likened to a pearl, symbolizing purity and innocence that should be preserved against the corruption of the world. The metaphor suggests that innocence is a fragile yet invaluable aspect of humanity that must be protected, especially during the formative years of childhood.

Hugo emphasizes that as long as a person retains their innocent heart, they embody an inherent goodness that reflects divine intention. This theme serves as a reminder of the importance of nurturing the innocence in individuals, highlighting how such purity is worthy of protection from the negative influences that can tarnish it. The quote encapsulates a central idea that innocence is a divine gift that should flourish, undeterred by the surrounding muck of life.
