The most delightful thing to such a man would be something that gave an extreme satisfaction to his sense of power and superiority; and if it involved, secondly, the triumphant exertion of his abilities, and, thirdly, the excitement of danger, his delight would be consummated. And the moment most dangerous to such a man would be one when his sense of superiority had met with an affront, so that its habitual craving was reinforced by resentment, while at the same time he saw an opportunity of satisfying it by subjecting to his will the very persons who had affronted it. Now, this is the temptation that comes to Iago. Othello's eminence, Othello's goodness, and his own dependence on Othello, must have been a perpetual annoyance to him. At any time he would have enjoyed befooling and tormenting Othello. Under ordinary circumstances he was restrained, chiefly by self-interest, in some slight degree perhaps by the faint pulsations of conscience or humanity. But disappointment at the loss of the lieutenancy supplied the touch of lively resentment that was required to overcome these obstacles; and the prospect of satisfying the sense of power by mastering Othello through an intricate and hazardous intrigue now became irresistible. Iago did not clearly understand what was moving his desire; though he tried to give himself reasons for his action, even those that had some reality made but a small part of the motive force; one may almost say they were no more than the turning of the handle which admits the driving power into the machine. Only once does he appear to see something of the truth. It is when he uses the phrase 'to plume up my will in double knavery.'
To 'plume up the will,' to heighten the sense of power or superiority—this seems to be the unconscious motive of many acts of cruelty which evidently do not spring chiefly from ill-will, and which therefore puzzle and sometimes horrify us most. It is often this that makes a man bully the wife or children of whom he is fond. The boy who torments another boy, as we say, 'for no reason,' or who without any hatred for frogs tortures a frog, is pleased with his victim's pain, not from any disinterested love of evil or pleasure in pain, but mainly because this pain is the unmistakable proof of his own power over his victim. So it is with Iago. His thwarted sense of superiority wants satisfaction. What fuller satisfaction could it find than the consciousness that he is the master of the General who has undervalued him and of the rival who has been preferred to him; that these worthy people, who are so successful and popular and stupid, are mere puppets in his hands, but living puppets, who at the motion of his finger must contort themselves in agony, while all the time they believe that he is their one true friend and comforter? It must have been an ecstasy of bliss to him. And this, granted a most abnormal deadness of human feeling, is, however horrible, perfectly intelligible. There is no mystery in the psychology of Iago; the mystery lies in a further question, which the drama has not to answer, the question why such a being should exist.
Iago's longing to satisfy the sense of power is, I think, the strongest of the forces that drive him on. But there are two others to be noticed. One is the pleasure in an action very difficult and perilous and, therefore, intensely exciting. This action sets all his powers on the strain. He feels the delight of one who executes successfully a feat thoroughly congenial to his special aptitude, and only just within his compass; and, as he is fearless by nature, the fact that a single slip will cost him his life only increases his pleasure. His exhilaration breaks out in the ghastly words with which he greets the sunrise after the night of the drunken tumult which has led to Cassio's disgrace: 'By the mass, 'tis morning. Pleasure and action make the hours seem short.' Here, however, the joy in exciting action is quickened by other feelings. It appears more simply elsewhere in such a way as to suggest that nothing but such actions gave him happiness, and that his happiness was greater if the action was destructive as well as exciting. We find it, for instance, in his gleeful cry to Roderigo, who proposes to shout to Brabantio in order to wake him and tell him of his daughter's flight:
Do, with like timorous[116] accent and dire yell
As when, by night and negligence, the fire
Is spied in populous cities.
All through that scene; again, in the scene where Cassio is attacked and Roderigo murdered; everywhere where Iago is in physical action, we catch this sound of almost feverish enjoyment. His blood, usually so cold and slow, is racing through his veins.
But Iago, finally, is not simply a man of action; he is an artist. His action is a plot, the intricate plot of a drama, and in the conception and execution of it he experiences the tension and the joy of artistic creation. 'He is,' says Hazlitt, 'an amateur of tragedy in real life; and, instead of employing his invention on imaginary characters or long-forgotten incidents, he takes the bolder and more dangerous course of getting up his plot at home, casts the principal parts among his newest friends and connections, and rehearses it in downright earnest, with steady nerves and unabated resolution.' Mr. Swinburne lays even greater stress on this aspect of Iago's character, and even declares that 'the very subtlest and strongest component of his complex nature' is 'the instinct of what Mr. Carlyle would call an inarticulate poet.' And those to whom this idea is unfamiliar, and who may suspect it at first sight of being fanciful, will find, if they examine the play in the light of Mr. Swinburne's exposition, that it rests on a true and deep perception, will stand scrutiny, and might easily be illustrated. They may observe, to take only one point, the curious analogy between the early stages of dramatic composition and those soliloquies in which Iago broods over his plot, drawing at first only an outline, puzzled how to fix more than the main idea, and gradually seeing it develop and clarify as he works upon it or lets it work. Here at any rate Shakespeare put a good deal of himself into Iago. But the tragedian in real life was not the equal of the tragic poet. His psychology, as we shall see, was at fault at a critical point, as Shakespeare's never was. And so his catastrophe came out wrong, and his piece was ruined.
Such, then, seem to be the chief ingredients of the force which, liberated by his resentment at Cassio's promotion, drives Iago from inactivity into action, and sustains him through it. And, to pass to a new point, this force completely possesses him; it is his fate. It is like the passion with which a tragic hero wholly identifies himself, and which bears him on to his doom. It is true that, once embarked on his course, Iago could not turn back, even if this passion did abate; and it is also true that he is compelled, by his success in convincing Othello, to advance to conclusions of which at the outset he did not dream. He is thus caught in his own web, and could not liberate himself if he would. But, in fact, he never shows a trace of wishing to do so, not a trace of hesitation, of looking back, or of fear, any more than of remorse; there is no ebb in the tide. As the crisis approaches there passes through his mind a fleeting doubt whether the deaths of Cassio and Roderigo are indispensable; but that uncertainty, which does not concern the main issue, is dismissed, and he goes forward with undiminished zest. Not even in his sleep—as in Richard's before his final battle—does any rebellion of outraged conscience or pity, or any foreboding of despair, force itself into clear consciousness. His fate—which is himself—has completely mastered him: so that, in the later scenes, where the improbability of the entire success of a design built on so many different falsehoods forces itself on the reader, Iago appears for moments not as a consummate schemer, but as a man absolutely infatuated and delivered over to certain destruction.

Iago stands supreme among Shakespeare's evil characters because the greatest intensity and subtlety of imagination have gone to his making, and because he illustrates in the most perfect combination the two facts concerning evil which seem to have impressed Shakespeare most. The first of these is the fact that perfectly sane people exist in whom fellow-feeling of any kind is so weak that an almost absolute egoism becomes possible to them, and with it those hard vices—such as ingratitude and cruelty—which to Shakespeare were far the worst. The second is that such evil is compatible, and even appears to ally itself easily, with exceptional powers of will and intellect. In the latter respect Iago is nearly or quite the equal of Richard, in egoism he is the superior, and his inferiority in passion and massive force only makes him more repulsive. How is it then that we can bear to contemplate him; nay, that, if we really imagine him, we feel admiration and some kind of sympathy? Henry the Fifth tells us:
There is some soul of goodness in things evil,
Would men observingly distil it out;
