I've wondered this for a long time. You know how the notes for texts never answer the really hard questions? Well here's one for modernists:
Why is Prufrock afraid to eat a peach?
a. Duh, fiber! It will give him the runs!
b. Duh, he's afraid the juice will run and get all over his nice white flannel trousers.
c. He wanted to say "medlar," but the editors made him change it. And he's afraid because he knows all the real lit characters are going to mock him.
d. Other. (Seriously, why? I'm tired of being clueless in front of poetry classes.)
In other observations: Remember how the little birds in the "General Prologue" sleep at night with an open eye because nature pricks them in their "courages"? And "courages" there is tied to the Latin for heart?
Have you noticed that Pertolote chides Chaunticleer for being heartless, meaning, in this case, without courage?
I bet he doesn't sleep at night with an open eye, either! If he did, he wouldn't have silly nightmares and need to eat a peach*.
