Ear-Poem: Cortney Davis, "Ear Examined"

In this poem, the discrepancy between the objective anatomy and the subjective experience of the body part (the ear) is in greater evidence than in the previous poem (the foot). What is the purpose of highlighting this tension?

Ear Examined

Cortney Davis

The doctor tugs the fleshy lobe, pulls up
and back, the canal thereby made straight.
Enter his probing speculum, its light a triangle
on the drum. Pearly, uninformed, it waits
for the otoscope's puff of air. Like a sheet
snapped by tiny chambermaids, it flaps,
teased by air to test its worth for sound:
those words we long for—a whispered oath, a lie.
A trickster, the ear. Making us believe
what eyes deny or hearts may doubt,

the narrow bones inside like a sparrow's
in flight, willing to trust the slightest breeze,
the one that sings Yes! I love you!—
as if words might mean exactly what was heard.
Oh the risk, the fragile wing.
