But the third scheme of Ulysses is the most subtle of all, and touches the heart of the whole problem, though it be merely a pun. He calls himself Nobody to Polyphemus, who, without sight or insight, is the victim of a word. For a complete man must have not only a double sight from his eyes, but a double insight from his mind, seeing before and after in the latter case especially. The result is when the other Cyclops, roused by the cries of Polyphemus, ask him from outside the cave: What is the matter? he answers, Nobody is killing me. Whereat off they go, dropping a word or two of cold advice, or perchance of sarcastic humor. We should, however, reach down to the essence of what appears on the surface as a mere trick of speech. It may seem far-fetched to say, but it is none the less the actual fact, that Ulysses is a Nobody, and a very active one to Polyphemus. That is, he has shown himself the negative power which overwhelms the giant, who is now himself quite reduced to a nobody by Mr. Nobody. Or, in abstract terms, Ulysses has negated the negation and has here suggested the subtle work of the process in doing so. Has he not negatived Polyphemus, who was himself a negative, so carefully and fully defined by the poet at the start? Thus we come upon the deepest pun ever made, or possible to be made, a literary form which the greatest geniuses have been fond of sporting with; we can find puns in Dante, Goethe, and notably in Shakespeare. The pun of Ulysses rests upon the duplicity inherent in the negative; no-man is the man, especially to Polyphemus, whose brain cannot span the two sides of the punning idea, who is not two-eyed but one-eyed by nature, and this one eye is soon put out by the man with two eyes. Such is the earliest instance of what may be called the Play of the Negative, which is still subtly ensconced in the spoken and written word, and winds in an elusive game of hide-and-seek through all Literature. Many men, both writers and readers, are its victims, like Polyphemus. And all these floating metaphysical gossamers are found in Homer! Yes, but not in a metaphysical form; Homer's organ is poetic, he lived in the age ere philosophers had dawned. Still he too had before him the problems of the soul and of the world. Nor would he have been a true Greek unless he had grappled with this Play of the Negative, which had some marvelous fascination for the Greek mind. It is the leaven working in the Sophists with their subtle rhetoric, in Socrates with his negating elenchus, in Plato with his confounding dialectic. Homer, as the prophet of his people, foreshadowing all forms of Greek spirit and of Greek literature, bring to light repeatedly this Play of the Negative.
