Answer:
Communication, Isolation of the Individual, & Rationality versus Imagination
Step-by-step explanation:
Communication
Communication, or the lack thereof, appears as a significant theme in several of Frost's poems, as Frost presents it as the only possible escape from isolation and despair. Unfortunately, Frost also makes it clear that communication is extremely difficult to achieve. For example, in "Home Burial," Frost describes two terrible events: the death of a child and the destruction of a marriage. The death of the child is tragic, but the inability of the husband and wife to communicate with each other and express their grief about the loss is what ultimately destroys the marriage. Frost highlights this inability to communicate by writing the poem in free verse dialogue; each character speaks clearly to the reader, but neither is able to understand the other. Frost explores a similar theme in "Acquainted with the Night," in which the narrator is unable to pull himself out of his depression because he cannot bring himself even to make eye contact with those around him. In each of these cases, the reader is left with the knowledge that communication could have saved the characters from their isolation. Yet, because of an unwillingness to take the steps necessary to create a relationship with another person, the characters are doomed.
Isolation of the Individual
This theme is closely related to the theme of communication. The majority of the characters in Frost's poems are isolated in one way or another. Even the characters who show no sign of depression or loneliness, such as the narrators in "The Sound of Trees" or "Fire and Ice," are still presented as detached from the rest of society, isolated because of their unique perspective. In some cases, isolation is a far more destructive force. For example, in "The Lockless Door," the narrator has remained in a "cage" of isolation for so many years that he is too terrified to answer the door when he hears a knock. This heightened isolation keeps the character from fulfilling his potential as an individual and ultimately makes him a prisoner of his own making. Yet, as Frost suggests, this isolation can be avoided by interactions with other members of society; if the character in "The Lockless Door" could have brought himself to open the door and face an invasion of his isolation, he could have achieved a greater level of personal happiness.
Rationality versus Imagination
This theme is similar to the theme of duty, in that the hardworking people whom Frost describes in his poetry are forced to choose between rationality and imagination; the two cannot exist simultaneously. The adults in Frost's poetry generally maintain their rationality as a burden of duty, but there are certain cases when the hint of imagination is almost too seductive to bear. For example, in "Birches," the narrator wishes that he could climb a birch tree as he did in his childhood and leave the rational world behind, if only for a moment. This ability to escape rationality and indulge in the liberation of imagination is limited to the years of childhood. After reaching adulthood, the traditions of New England life require strict rationality and an acceptance of responsibility. As a result of this conflict, Frost makes the poem "Out, Out--" even more tragic, describing a young boy who is forced to leave his childhood behind to work at a man's job and ultimately dies in the process.
