According to Poe's fabricated account in the essay, he chose "Nevermore" as the refrain for the following reasons:
* Length: It's a monosyllabic word, maximizing impact and creating a sense of repetition.
* Sound: It's a somber and haunting sound, perfectly aligning with the poem's overall tone.
* Meaning: It reflects the poem's central themes of loss, despair, and the impossibility of escaping sorrow.
Poe also claims that he considered a variety of other words before settling on "Nevermore," but ultimately decided it was the most effective.
However, it's important to note that:
* The essay is likely a literary fiction, and Poe may have been exaggerating or even fabricating his process for artistic effect.
* It's unlikely that Poe actually planned out the entire poem with such meticulous detail as he claims.
* Even if he considered these factors, it's impossible to know for certain if they were the sole or even primary reasons for his choice.
While "The Philosophy of Composition" offers a captivating and thought-provoking account of Poe's process, it's crucial to approach it with a healthy dose of skepticism.
