In Victor Hugo's "Les Miserables," the author highlights the impact of errors as powerful tools that can expose weaknesses in reasoning or flaws in a system. Mistakes can effectively penetrate defenses, revealing vulnerabilities where logic is deficient. Hugo suggests that these missteps serve as sharp critiques of existing structures, emphasizing that errors can highlight the need for change or improvement.

This perspective encourages reflection on the value of learning from mistakes. Rather than merely viewing errors as setbacks, Hugo implies they can be instrumental in fostering growth and understanding. By acknowledging and addressing these faults, individuals and societies can strive for greater resilience and insight.
