The speaker is an aging man, based on poet Jorge Luis Borges, who is slowly losing his eyesight in his fifties. He lives in Buenos Aires and spends his time contemplating his relationship with literature, memory, and the physical decline of his body. Instead of fearing his blindness, he embraces the encroaching shadows as a return to his true center and identity. He categorizes humans into physical material, which dies, and enduring spirit, which lives on.

An ancient Greek philosopher and atomist referenced in the speaker's thoughts. According to legend, he plucked out his own eyes to gain greater mental clarity and remove the material world's visual distractions. The speaker equates this deliberate physical blinding to the natural, painless process of his own failing sight.

An allusion to Shakespeare's Prince Hamlet, specifically evoking the character's staunch sword. He represents action, unflinching resolve, and the enduring power of classic literature in the speaker's vast internal memory.

A 19th-century American Transcendentalist writer who occupies a prominent place in the speaker's literary memory. He serves as an intellectual anchor for the speaker as the aging man retreats into his mind's eye.
