"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 would - that he will never get over it. That is to say, permanence in poetry, as in love, is perceived instantly. It hasn't to await the test of time. The proof of a poem is not that we have never forgotten it, but we knew at sight we never could forget it."
