“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, I am not what I am, is correct and the negation of the Divine I am that I am. If the word motive is given its normal meaning of a positive purpose of the self like sex, money, glory, etc., then the practical joker is without motive. Yet the professional practical joker is certainly driven, like a gambler, to his activity, but the drive is negative, a fear of lacking concrete self, of being nobody.”

“All practical jokes, friendly, harmless or malevolent, involve deception, but not all deceptions are practical jokes. The two men digging up the street, for example, might have been two burglars who wished to recover some swag which they knew to be buried there. But, in that case, having found what they were looking for, they would have departed quietly and never been heard of again, whereas, if they are practical jokers, they must reveal afterwards what they have done or the joke will be lost. The practical joker must not only deceive but also, when he has succeeded, unmask and reveal the truth to his victims. The satisfaction of the practical joker is the look of astonishment on the faces of others when they learn that all the time they were convinced that they were thinking and acting on their own initiative, they were actually the puppets of another’s will. Thus, though his jokes may be harmless in themselves and extremely funny, there is something slightly sinister about every practical joker, for they betray him as someone who likes to play God behind the scenes. […] The success of a practical joker depends upon his accurate estimate of the weaknesses of others, their ignorances, their social reflexes, their unquestioned presuppositions, their obsessive desires, and even the most harmless practical joke is an expression of the joker’s contempt for those he deceives.”

“As his wife, Emilia must know Iago better than anybody else. She does not know, any more than the others, that he is malevolent, but she does know that her husband is addicted to practical jokes. What Shakespeare gives us in Iago is a portrait of a practical joker of a peculiarly appalling kind, and perhaps the best way of approaching the play is by a general consideration of the Practical Joker.”

“Coleridge’s description of Iago’s actions as "motiveless malignancy" applies in some degree to all the Shakespearian villains. The adjective motiveless means, firstly, that the tangible gains, if any, are clearly not the principal motive, and, secondly, that the motive is not the desire for personal revenge upon another for a personal injury. Iago himself proffers two reasons for wishing to injure Othello and Cassio. He tells Roderigo that, in appointing Cassio to be his lieutenant, Othello has treated him unjustly, in which conversation he talks like the conventional Elizabethan malcontent. In his soliloquies with himself, he refers to his suspicion that both Othello and Cassio have made him a cuckold, and here he talks like the conventional jealous husband who desires revenge. But there are, I believe, insuperable objections to taking these reasons, as some critics have done, at their face value.”

“He who despises himself, nevertheless esteems himself as a self-despiser. (Nietzsche.)A vain person is always vain about something. He overestimates the importance of some quality or exaggerates the degree to which he possesses it, but the quality has some real importance and he does possess it to some degree. The fantasy of overestimation or exaggeration makes the vain person comic, but the fact that he cannot be vain about nothing makes his vanity a venial sin, because it is always open to correction by appeal to objective fact.A proud person, on the other hand, is not proud of anything, he is proud, he exists proudly. Pride is neither comic nor venial, but the most mortal of all sins because, lacking any basis in concrete particulars, it is both incorrigible and absolute: one cannot be more or less proud, only proud or humble.Thus, if a painter tries to portray the Seven Deadly Sins, his experience will furnish him readily enough with images symbolic of Gluttony, Lust, Sloth, Anger, Avarice, and Envy, for all these are qualities of a person’s relations to others and the world, but no experience can provide an image of Pride, for the relation it qualifies is the subjective relation of a person to himself. In the seventh frame, therefore, the painter can only place, in lieu of a canvas, a mirror.”

“Iago’s treatment of Othello conforms to Bacon’s definition of scientific enquiry as putting Nature to the Question. If a member of the audience were to interrupt the play and ask him: "What are you doing? could not Iago answer with a boyish giggle, "Nothing. I’m only trying to find out what Othello is really like"? And we must admit that his experiment is highly successful. By the end of the play he does know the scientific truth about the object to which he has reduced Othello. That is what makes his parting shot, What you know, you know, so terrifying for, by then, Othello has become a thing, incapable of knowing anything.And why shouldn’t Iago do this? After all, he has certainly acquired knowledge. What makes it impossible for us to condemn him self-righteously is that, in our culture, we have all accepted the notion that the right to know is absolute and unlimited. […] We are quite prepared to admit that, while food and sex are good in themselves, an uncontrolled pursuit of either is not, but it is difficult for us to believe that intellectual curiosity is a desire like any other, and to realize that correct knowledge and truth are not identical. To apply a categorical imperative to knowing, so that, instead of asking, "What can I know?" we ask, "What, at this moment, am I meant to know?" – to entertain the possibility that the only knowledge which can be true for us is the knowledge we can live up to – that seems to all of us crazy and almost immoral. But, in that case, who are we to say to Iago – "No, you mustn’t.”

“Cassio is a ladies’ man, that is to say, a man who feels most at home in feminine company where his looks and good manners make him popular, but is ill at ease in the company of his own sex because he is unsure of his own masculinity.[…]Cassio is a ladies’ man, not a seducer. With women of his own class, what he enjoys is socialized eroticism; he would be frightened of a serious personal passion. For physical sex he goes to prostitutes and when, unexpectedly, Bianca falls in love with him, like many of his kind, he behaves like a cad and brags of his conquest to others.”
