In Philip K. Dick's "The Man in the High Castle," the characters grapple with the uncertainty of their existence, comparing themselves to blind moles navigating through darkness. This metaphor highlights their lack of understanding of the world around them and the confusion that arises from living in an altered reality.

The quote suggests a deep sense of fear and disorientation as the characters confront their limitations and the overwhelming complexity of their environment. As they realize their ignorance, they are left with a primal instinct to flee, emphasizing the struggle for survival in a world that is as oppressive as it is unclear.
