The light is buried under chains and noises
in impudent challenge of rootless science.
Through the suburbs sleepless people stagger,
as though just delivered from a shipwreck of blood.

These lines evoke an urban, mechanized modernity in which “light” (clarity, spirit, humane meaning) is smothered by industrial “chains and noises” and by an aggressive, dehumanized rationalism (“rootless science”). The imagery of sleepless suburban crowds “stagger[ing]” like survivors of a “shipwreck of blood” suggests collective trauma: people reduced to exhausted bodies moving through a landscape of violence and alienation. The poem’s surreal, catastrophic metaphors turn the city into a moral and psychological disaster zone, implying that progress and technical knowledge, when severed from roots—tradition, community, ethical feeling—can become an “impudent challenge” to life itself.
