If external action is effete
and rhyme is outmoded,
I shall revert to you,
Habakkuk, as when in a Bible class
the teacher was speaking of unrhymed verse.
He said - and I think I repeat his exact words -
"Hebrew poetry is prose
with a sort of heightened consciousness." Ecstasy affords
the occasion and expediency determines the form.

Marianne Moore
