William Shakespeare: Othello, Moor of Venice

ACT III. 3. SCENE III. Cyprus. The Garden of the Castle. (continued)

IAGO.
You cannot, if my heart were in your hand;
Nor shall not, whilst 'tis in my custody.

OTHELLO.
Ha!

IAGO.
O, beware, my lord, of jealousy;
It is the green-ey'd monster which doth mock
The meat it feeds on: that cuckold lives in bliss
Who, certain of his fate, loves not his wronger;
But O, what damned minutes tells he o'er
Who dotes, yet doubts, suspects, yet strongly loves!

OTHELLO.
O misery!

IAGO.
Poor and content is rich, and rich enough;
But riches fineless is as poor as winter
To him that ever fears he shall be poor;--
Good heaven, the souls of all my tribe defend
From jealousy!

OTHELLO.
Why, why is this?
Think'st thou I'd make a life of jealousy,
To follow still the changes of the moon
With fresh suspicions? No; to be once in doubt
Is once to be resolv'd: exchange me for a goat
When I shall turn the business of my soul
To such exsufflicate and blown surmises,
Matching thy inference. 'Tis not to make me jealous,
To say my wife is fair, feeds well, loves company,
Is free of speech, sings, plays, and dances well;
Where virtue is, these are more virtuous:
Nor from mine own weak merits will I draw
The smallest fear or doubt of her revolt;
For she had eyes and chose me. No, Iago;
I'll see before I doubt; when I doubt, prove;
And on the proof, there is no more but this,--
Away at once with love or jealousy!

IAGO.
I am glad of it; for now I shall have reason
To show the love and duty that I bear you
With franker spirit: therefore, as I am bound,
Receive it from me:--I speak not yet of proof.
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.
I know our country disposition well;
In Venice they do let heaven see the pranks
They dare not show their husbands; their best conscience
Is not to leave undone, but keep unknown.
