But, in most cases, behind the joker's contempt for others lies something else, a feeling of self-insufficiency, of a self lacking in authentic feelings and desires of its own. The normal human being may have a fantastic notion of himself, but he believes in it; he thinks he knows who he is and what he wants so that he demands recognition by others of the value he puts upon himself and must inform others of what he desires if they are to satisfy them.
But the self of the practical joker is unrelated to his joke. He manipulates others but, when he finally reveals his identity, his victims leam nothing about his nature, only something about their own; they know how it was possible for them to be deceived but not why he chose to deceive them. The only answer that any practical joker can give to the question: "Why did you do this?" is Iago's: "Demand me nothing. What you know, you know."
In fooling others, it cannot be said that the practical joker satisfies any concrete desire of his nature; he has only demonstrated the weaknesses of others and all he can now do, once he has revealed his existence, is to bow and retire from the stage. He is only related to others, that is, so long as they are unaware of his existence; once they are made aware of it, he cannot fool them again, and the relation is broken off.
The practical joker despises his victims, but at the same time he envies them because their desires, however childish and mistaken, are real to them, whereas he has no desire which he can call his own. His goal, to make game of others, makes his existence absolutely dependent upon theirs; when he is alone, he is a nullity. Iago's self-description,
Equally applicable to Iago is Valery's "Ebauche d'un serpent." The serpent speaks to God the Creator thus
And of himself thus
the ideal motto, surely, for Iago's coat of arms.
Since the ultimate goal of Iago is nothingness, he must not only destroy others, but himself as well. Once Othello and Desdemona are dead his "occupation's gone."
