Fire and Ice, a poem by Robert Frost, displays the tone of being content and at peace, but aware as well. I feel that these are tones that are applicable because it talks about how the author knows that there will most likely be an end of the Earth, but he doesn't seem alarmed. Instead, he talks about the ways it could end in a manner that seems more calm than anything else.
The theme of Robert Frost's poem, Fire and Ice, is that a burning desire, as well as a cold heart, could be destructive.
I believe that within the poem, fire represents a desire, and ice represents being heartless. The poem displays how either way, they can be harmful and destructive.
