It is possible for a person to contend that a poem is nothing but black marks on white paper. And such an argument might be convincing before an audience that could not read. You can examine the print under a microscope or analyze the paper and ink but you will never find something behind this sort of analysis that you could call “a poem.” Those who can read, however, will continue to insist that poems exist.
