The document summarizes the poem "Fire and Ice" by Robert Frost. In three lines, the poem discusses the debate around how the world will end, with some believing it will end in fire while others think it will end in ice. The speaker sides with those who believe it will end in fire, as they have experienced hatred, which they associate with ice. If the world had to end twice, the speaker thinks they would then understand enough about hate to believe the world could end in ice.
