ASSURANCE, by             Poet Analysis     Poet's Biography

"Assurance" by Robert Frost is a brief but potent exploration of the concept of safety and the psychological comfort derived from physical barriers. The poem succinctly captures the essence of feeling protected from external threats through the use of metaphorical language.

The poem reads:

"The danger not an inch outside

Behind the porthole's slab of glass

And double ring of fitted brass

I trust feels properly defied."

In these four lines, Frost conveys a sense of security and trust in the protective measures taken against potential dangers. The "danger not an inch outside" immediately establishes the proximity of the threat, suggesting that it is very close, perhaps just beyond reach. This immediacy heightens the tension and underscores the need for effective protection.

The "porthole's slab of glass" and the "double ring of fitted brass" are metaphorical representations of barriers that stand between the speaker and the outside world. The porthole, typically found on ships, symbolizes a window to the outside world that is strong and secure. The use of "slab of glass" suggests thickness and durability, while the "double ring of fitted brass" emphasizes precision and strength, indicating that the porthole is well-constructed and reliable.

The phrase "I trust feels properly defied" reflects the speaker's confidence in these barriers. The word "trust" implies a deep-seated belief in the effectiveness of the protections in place. The term "properly defied" suggests that the danger is not merely kept at bay but is actively and appropriately resisted. This implies a level of assurance and comfort that comes from knowing that the measures taken are sufficient to counteract the threat.

Frost's choice of language and imagery in "Assurance" creates a vivid picture of a secure environment. The poem's concise structure and precise wording enhance its impact, delivering a powerful message about the relationship between physical barriers and psychological peace. The "porthole's slab of glass" and the "double ring of fitted brass" are not just physical objects but symbols of trust and assurance, representing the speaker's faith in the structures that protect them.

In a broader sense, "Assurance" can be interpreted as a reflection on the human need for security and the comfort derived from knowing that protective measures are in place. It speaks to the importance of having confidence in the systems and structures that safeguard us from harm. This can apply to various contexts, whether physical, emotional, or societal, highlighting the universal desire for safety and the peace of mind it brings.

Through its succinct and evocative language, "Assurance" by Robert Frost effectively conveys the theme of security and trust in protective barriers. The poem invites readers to consider the importance of feeling protected and the psychological comfort that comes from knowing that dangers are kept at bay by reliable and trusted measures.
