Though a powerful motivating force in the novel, the human drive to understand proves to have limits as well as uses. The need to understand the unknown is an inherent quality of human nature that propels society forward and gives both groups and individuals a sense of purpose and direction. Because the primary and secondary characters in the story are researchers of some type, the novel places weight and value on this drive for understanding and knowledge, which grows in importance throughout the novel. Tonner explicitly argues for its inherent value after the second Night Drinkers attack, believing that if they survive at all, it will be because of their drive to understand.

Dafyd likewise believes in the value of understanding and knowledge. However, his drive to learn leads him in a different direction than Tonner. While Tonner narrows his focus to scientific discovery, largely because it’s the realm he’s most comfortable with and can best control, Dafyd turns his attention to learning about the Carryx themselves. He uses his skill at analyzing behavior and sociological conditions, as well as his political savvy, to observe and understand Carryx culture, behavior, and motives. This attempt to understand extends to communicating with the other species, fueling his efforts to acquire a black box translator.
