Keep up your bright swords, for the dew will rust them.

And the same self-control is strikingly shown where Othello endeavours to elicit some explanation of the fight between Cassio and Montano.  Here, however, there occur ominous words, which make us feel how necessary was this self-control, and make us admire it the more: 

                          Now, by heaven,
     My blood begins my safer guides to rule,
     And passion, having my best judgment collied,
     Assays to lead the way.

We remember these words later, when the sun of reason is ‘collied,’ blackened and blotted out in total eclipse.

Lastly, Othello’s nature is all of one piece.  His trust, where he trusts, is absolute.  Hesitation is almost impossible to him.  He is extremely self-reliant, and decides and acts instantaneously.  If stirred to indignation, as ‘in Aleppo once,’ he answers with one lightning stroke.  Love, if he loves, must be to him the heaven where either he must live or bear no life.  If such a passion as jealousy seizes him, it will swell into a well-nigh incontrollable flood.  He will press for immediate conviction or immediate relief.  Convinced, he will act with the authority of a judge and the swiftness of a man in mortal pain.  Undeceived, he will do like execution on himself.

This character is so noble, Othello’s feelings and actions follow so inevitably from it and from the forces brought to bear on it, and his sufferings are so heart-rending, that he stirs, I believe, in most readers a passion of mingled love and pity which they feel for no other hero in Shakespeare, and to which not even Mr. Swinburne can do more than justice.  Yet there are some critics and not a few readers who cherish a grudge against him.  They do not merely think that in the later stages of his temptation he showed a certain obtuseness, and that, to speak pedantically, he acted with unjustifiable precipitance and violence; no one, I suppose, denies that.  But, even when they admit that he was not of a jealous temper, they consider that he was ’easily jealous’; they seem to think that it was inexcusable in him to feel any suspicion of his wife at all; and they blame him for never suspecting Iago or asking him for evidence.  I refer to this attitude of mind chiefly in order to draw attention to certain points in the story.  It comes partly from mere inattention (for Othello did suspect Iago and did ask him for evidence); partly from a misconstruction of the text which makes Othello appear jealous long before he really is so;[96] and partly from failure to realise certain essential facts.  I will begin with these.
