Which poem addresses the theme of duality in human experience?

The poem that best addresses the theme of duality in human experience is "Fire and Ice" by Robert Frost. In this work, the poet explores two opposing forces—fire, representing desire and passion, and ice, symbolizing hatred and indifference. The poem frames the human experience as a struggle between these contrasting emotions and states of being, reflecting on how both love and hate can lead to destruction. This duality inherent in "Fire and Ice" captures the complexity of human emotions and the ways they can influence our actions and existence.

While "Sunflower Sutra," "Death be not proud," and "A Supermarket in California" each delve into significant themes such as nature, mortality, and societal critique, they do not engage with the concept of duality in the same direct manner as Frost's poem, which explicitly juxtaposes conflicting concepts to illustrate the intricacies of human experience.
