In Victor Hugo's "Les Misérables," a poignant observation is made about the nature of fear and illumination. The quote suggests that while the light from torches may provide some guidance, it lacks strength and clarity because it flickers and trembles. This reflects the uncertainty often found in the actions of those who live in fear, showcasing that their wisdom is dim and not truly illuminating.

This metaphor serves to highlight the contrast between genuine enlightenment and the feeble understanding that arises from cowardice. The trembling light may offer some visibility, but it ultimately fails to provide the firm foundation of true wisdom. This idea invites readers to contemplate the difference between superficial knowledge born of fear and the strength found in courageous insight.
