The ear is the only true writer and the only true reader. I know people who read without hearing the sentence sounds and they were the fastest readers. Eye readers we call them. They get the meaning by glances. But they are bad readers because they miss the best part of what a good writer puts into his work.
It is absurd to think that the only way to tell if a poem is lasting is to wait and see if it lasts. The right reader of a good poem can tell the moment it strikes him that he has taken an immortal wound-that he will never get over it.
