In Denis Johnson's novel "Tree of Smoke," the quote "We in Purgatory sing fondly of Hell" suggests a complex relationship between suffering and nostalgia. It implies that those who endure the liminal state of Purgatory reflect on the harsh realities of Hell with a sense of longing. This dynamic indicates a recognition that even in great suffering, there can be a twisted admiration for the extremities of pain experienced in Hell.

This line invites readers to contemplate the nature of human experience, particularly how individuals cope with their struggles. It emphasizes the idea that memories of torment can bring a form of comfort or connection, transforming suffering into a shared narrative. Johnson’s work often explores themes of war, loss, and redemption, and this quote encapsulates the tension between despair and a yearning for understanding amidst chaos.
