In "Oryx and Crake," Margaret Atwood explores themes of memory, loss, and the impact of language. The quoted words highlight the fragility of existence and the permanence of absence. When thoughts and words fade from someone’s mind, they vanish completely, leaving no trace behind, as if they never mattered at all. This emphasizes the idea that language carries memories and identity; once lost, they cannot be reclaimed.

The statement invites reflection on the significance of our expressions and the connections they foster. Atwood's narrative underscores how easily memories can disperse and how important it is to acknowledge and preserve our experiences. The loss of words symbolizes a broader commentary on humanity's relationship with knowledge and understanding, suggesting that what we do not articulate may cease to exist in the larger context of history and culture.
