In Philip K. Dick's "A Scanner Darkly," the quote about the worm emphasizes the struggle for existence and the often grim nature of life. The worm symbolizes an individual who lives in a harsh environment, subsisting on what is available but ultimately vulnerable to greater forces beyond its control. This imagery reflects the human experience of being caught in a cycle of survival, facing existential threats that can suddenly alter one's fate.
The worm's existence in dust conveys a sense of decay and obscurity, highlighting the fragility of life. The mention of a passerby suggests that people often overlook the struggles of those around them, further illustrating themes of alienation and moral indifference in society. This resonance within the narrative serves as a poignant commentary on the nature of oppression and the impact of societal neglect on individuals trapped in a system that sometimes seems indifferent to their plight.
