In this excerpt from Hilary Mantel's "Bring Up the Bodies," the conversation revolves around the metaphorical dilemma posed by the "great worm." The father grapples with the significance of taking action against it, reflecting on his son's suggestion to address the issue through a commission. This implies a larger theme of confronting painful truths, even when those truths may disrupt the comfort of beliefs.

Gregory, the son, acknowledges the fable's fictional nature but expresses a bittersweet understanding of its impact on people's happiness. The dialogue highlights the tension between reality and illusion, illustrating how stories, even those recognized as false, can bring joy. This exchange encapsulates the struggle between duty and the comforting power of belief, leaving readers to ponder the consequences of their choices.
