The discursive writer writes as an act of conscious will, and that conscious will, along with the symbolic system he employs for it, is set over against the body of things he is describing.
But the poet, who writes creatively rather than deliberately, is not the father of his poem; he is at best a midwife, or, more accurately still, the womb of Mother Nature herself: her privates, he, so to speak.
The fact that revision is possible, that a poet can make changes in a poem not because he likes them better but because they are better, shows clearly that the poet has to give birth to the poem as it passes through his mind.
He is reponsible for delivering it in as uninjured a state as possible, and if the poem is alive, it is equally anxious to be rid of him, and screams to be cut loose from all the navel-strings and feeding-tubes of his ego.
