"Fire and Ice" by Robert Frost.

Some say the world will end in fire, some say in ice. In that statement, Robert Frost believes that the world will end in one of these two fates. Literally, fire could possibly end the world, for fire destroys. On the contrary, ice could end human existence as we know it; another ice age. That itself is already a thought that has puzzled many philosophers and scientists throughout time. However, looking at this poem symbolically …

…suffice. Also, this poem shows that while man has no control over nature, he does have a sort of creative choice as to how nature accomplishes what it does. The outward theme is, we will end from desire or hate. A sort of inward theme could be man's lack of control over nature. I think that is why this is one of Frost's poems where he does not come to a definitive conclusion or ending.
