Some say in ice.
From what I've tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
The end of the world has been on everyone's mind at least once. I know it was definitely trending during winter of last year, the days leading up to December 21st. The end of days is a topic that's always been highly debated, whether it's about its time of occurrence or actual existence.
From a literal direction, Robert Frost is speaking of the world's destruction. Will the world burn or freeze? He acknowledges the destructive capabilities of both fire and ice, that either one would sufficiently fulfill the task of ending the world. However, in addition to their cataclysmic characteristics, he also wrote of their association with "desire" and "hate." Fire and ice, therefore, could be interpreted as "passion" and "loathing."
Passion has often been described as "burning," a quality that could also be associated with fire. When one has a burning passion for something, their yearning is so intent and raw that they'll go to any means to fulfill their want. The individual is consumed by this wish, just as a blazing fire consumes everything in its path. Usually the individual who is passionate is highly expressive of his or her passion, whether it be verbally or visually. The idea of passion revolves around the concept of being able to share that passion to others. Therefore, the passion, or fire, is able to be acknowledged and spread to many people at a time.
Ice can be considered of a preserving nature, freezing life and inhibiting growth. This restraint can be similar to hate, which is often times bottled up within an individual. Just as passion consumes an individual, loathing limits an individual. If someone's described as cold-hearted, they're said to lack affection and only display emotions of hate. Just as their "heart" is cold, as is their nature; their attitudes of hate are piercing and biting, similar to the qualities of ice.
An example of the downfalls that come from these qualities could be from Mary Shelley's Frankenstein. Passion could be found in Victor Frankenstein, the creator who eventually gets caught up and consumed with the idea of glory and fame. Loathing could be found in Frankenstein's creation, who lived the entirety of his life without love and care. Both characters met their demise as a result of these characteristics, neither of them really obtaining what they had always wanted -- pride for Frankenstein and love for his creation.
The downfall of the world due to either passion or loathing, according to Robert Frost, is neither here nor there. With his attitude, Frost believes that while the end is inevitable, the means through which it occurs is unimportant. By using the word "suffice," it seems as though Robert is acting flippant towards the controversy of how the world will end. Despite the harsh reality of it all, his unconcern portrays him as accepting of the world's eventual fate.
