Both works use the theme of death to emphasize the meaninglessness in human action. In the poem, the theme of death is seen in how nature moves on, almost outside of the realm of human action. The wars that have been waged for lofty principles and ideals have little in terms of relevance. “If mankind perished utterly” is reflective of the poem's theme of death. This same sense of meaninglessness is present in Bradbury's story, where human action has helped to construct the greatest in technological marvels. Yet, it has also played a role in its own extinction and destruction.
Both works develop themes in which human action has resulted in the vast reality of death, a condition in which individual action is reduced to a condition of absurd meaninglessness. The element of detachment in both works help to establish this. Bradbury and Teasdale feature conditions in which an existential reality of human destruction is a part of being in the world. The continuation of nature in Teasdale's work and the function of Bradbury's house are elements that will continue on long after human beings are gone, helping to enhance the theme of detachment in both works.
