Which sentence or phrase reflects the theme that nature is indifferent to the troubles of man in this excerpt from "the open boat" by stephen crane?

Well, since you didn't include the excerpt here in your question, I'm going to have to make an educated guess. I'd say that the answer is this sentence: "When it occurs to a man that nature does not regard him as important, and that she feels she would not maim the universe by disposing of him, he first wishes to throw bricks at the temple, and he hates deeply the fact that there are no bricks an no temple."
