In the book "Catch-22" by Joseph Heller, the quote "The spirit gone, man is garbage" encapsulates the idea that without a sense of purpose or vitality, human existence loses its value. The phrase suggests that when the essence of a person is absent, they become like discarded waste, devoid of meaning and hope. This reflects the broader themes of the novel, which critiques the dehumanizing effects of war and bureaucracy.

Heller's work explores the absurdities of military life and the struggles individuals face in maintaining their integrity and spirit amid chaotic circumstances. This quote serves as a poignant reminder of the importance of spirit and individuality, emphasizing that without these qualities, one’s life may feel empty and worthless.
