In "The Devil in the White City," Erik Larson explores the contrasting narratives of the 1893 Chicago World's Fair and the serial killer H.H. Holmes. Amid the grandeur of the fair, architect Daniel Burnham emphasizes the importance of grand visions, famously stating, "Make no little plans; they have no magic to stir men's blood." This quote encapsulates his belief that ambitious projects inspire passion and unity among people, serving as a driving force for innovations that can transform society.

Burnham's philosophy reflects the larger themes of ambition and creativity within the book. While the fair represents the heights of human ingenuity and hope for progress, the chilling presence of Holmes depicts the darker aspects of human nature. Together, these elements illustrate how monumental undertakings can evoke both inspiration and horror, reminding us that great aspirations can coexist with great evils in the tapestry of history.
