In the story of The Open Boat the idea is in keeping with the theme of the story that humans are what

Despite the narrator’s profusion of animistic (animal-like), humanistic (manlike), and deistic (godlike) characterizations of nature, Crane makes clear that nature is ultimately indifferent to the plight of man, possessing no consciousness that we can understand. As the stranded men progress through the story, the reality of nature’s lack of concern for them becomes increasingly clear. The narrator highlights this development by changing the way he describes the sea. Early in the story, the sea snarls, hisses, and bucks like a bronco; later, it merely "paces to and fro," no longer an actor in the men’s drama. In reality, the sea does not change at all; only the men’s perception of the sea changes. The unaltered activity of the gulls, clouds, and tides illustrates that nature does not behave any differently in light of the men’s struggle to survive.
