CHAPTER XIX THE WORRIES OF JEALOUSY A prolific source of worry is jealousy; not only the jealousy that exists between men and women, but that exists between women and women, and between men and men. There are a thousand forms that this hideous monster of evil assumes, and when they have been catalogued and classified, another thousand will be found awaiting, around the corner, of entirely different categories. But all alike they have one definite origin, one source, one cause. And that cause, I am convinced, is selfishness. We wish to own, to dominate, to control, absolutely, entirely, for our own pleasure, and satisfaction, that of which we are jealous. In Chapter One I tell the incident of the young man on the street car whose jealous worry was so manifest when he saw his "girl" smiling upon another man. I suppose most men and women feel, or have felt, at some time or other, this sex jealousy. That woman belongs to _me_, her smiles are _mine_, her pleasant words should fall on _my_ ear alone; _I_ am her lover, she, the mistress of _my_ heart; and that should content her. Every writer of the human heart has expatiated upon this great source of worry--jealousy. Shakspere refers to it again and again. The whole play of _Othello_ rests upon the Moor's jealousy of his fair, sweet, and loyally faithful Desdemona. How the fiendish Iago plays upon Othello's jealous heart until one sees that: Trifles, light as air, Are to the jealous confirmations strong As proofs of holy writ. Iago bitterly resents a slight he feels Othello has put upon him. With his large, generous, unsuspicious nature, Othello never dreams of such a thing; he trusts Iago as his intimate friend, and thus gives the crafty fiend the oportunity he desires to put the Moor Into a jealousy so strong That judgment cannot cure ... Make the Moor thank me, love me, reward me, For making him egregiously an ass And practicing upon his peace and quiet Even to madness. Othello gives his wife, Desdemona, a rare handkerchief. Iago urges his own wife, who is Desdemona's maid, to pilfer this and bring it to him. When he gets it, he leaves it in Cassio's room. Cassio was an intimate friend of Othello's, one, indeed, who had gone with him when he went to woo Desdemona, and who, by Iago's machinations, had been suspended from his office of Othello's chief lieutenant. To provoke Othello's jealousy Iago now urges Desdemona to plead Cassio's cause with her husband, and at the came time eggs on Othello to watch Cassio: Look to your wife; observe her well with Cassio; Wear your eye thus, not jealous nor secure. I would not have your free and noble nature Out of self-bounty be abus'd; look to 't. Thus he works Othello up to a rage, and yet all the time pretends to be holding him back: I do see you're mov'd; I pray you not to strain my speech To grosser issues nor to larger reach Than to suspicion.
