In Victor Hugo's "Les Miserables," the quote reflects on the moral implications of comfort and materialism, suggesting it is unjust for something as mundane as a mattress to hold such significant influence over people's lives. The juxtaposition between the power of a bed and powerful weapons insinuates a critique of society's values, where comfort can overshadow the more noble pursuits of strength and action.

The phrase "triumph of that which yields over that which strikes with lightning" highlights a contrast between pacifism and violence, calling into question the priorities of humanity. Hugo's admiration for the mattress, which nullifies the destructive power of a cannon, serves as a metaphor for peace over war, challenging readers to consider the true source of power and the morality behind their choices.
