The quote from "The Devil in the White City" reflects a perspective on the value of life in relation to the completion of one's work. It suggests that once a person has fulfilled their purpose and contributed meaningfully, the extension of their life holds little significance. This viewpoint challenges the often-held notion that longevity is inherently valuable, proposing instead that the quality of one’s contributions is what truly matters.

In the context of the book, this idea resonates with the historical backdrop of the World's Columbian Exposition and the lives intertwined within it, showcasing how achievements and legacies can overshadow mere existence. Larson weaves a narrative that examines both the brilliance of human endeavors and the darker aspects of life, forcing readers to confront the complexity of mortality and purpose.
