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.
Robert FrostI shall set forth for somewhere, I shall make the reckless choice Some say when they are in voice And tossing so as to scare The white clouds over them on, I shall have less to say, But I shall be none.
Robert Frost
