In Victor Hugo's "Les Misérables," the character's struggles illustrate the profound social injustices of 19th-century France. One of the key themes is the idea that ignorance and denial can blind individuals to the truth around them. This quote, "Blind is he who will not see," serves as a powerful reminder of the importance of awareness and understanding. It emphasizes that true blindness comes from a refusal to acknowledge reality, rather than a lack of physical sight.

The narrative challenges readers to confront their own perceptions and be vigilant against the apathy that can lead to societal decay. By encouraging self-reflection, Hugo advocates for a compassionate society where individuals choose to see and act upon the plight of others. This call for awareness is especially relevant in addressing moral and social issues, urging people not to turn a blind eye to suffering and injustice.
