The quote suggests that not every expression that fades away holds absolute truth, yet they can still offer genuine comfort or insight. This implies that even in dire circumstances or the loss of meaning, the essence of what is said can still resonate deeply with individuals, reflecting the human experience's complexity.

The passage highlights the idea that words can possess intrinsic value, regardless of their origins or the circumstances around them. In a world often marked by chaos and despair, the sentiments expressed can still provide solace, reminding us that emotional sincerity can thrive even when the foundations of meaning seem shaky. McCarthy’s narrative captures the resilience of the human spirit through such reflections on language and understanding.
