The dialogue between Rigg and his father highlights a fundamental lesson about knowledge and self-awareness. Rigg expresses a sense of confidence in what he already understands, but his father challenges him by pointing out that his perceived knowledge is limited. This exchange emphasizes the idea that true insight comes from recognizing one's own ignorance and the complexities of what one does not yet understand.

Furthermore, the conversation suggests that ignorance can have serious consequences, underscoring the importance of seeking knowledge beyond one's immediate understanding. Rigg's father's message implies that an awareness of one’s limitations is critical in the pursuit of wisdom, and acknowledging what one doesn’t know is the first step toward enlightenment. This theme resonates throughout the narrative, driving characters to confront their understanding of the world around them.
