IAGO

My lord, for aught I know.

OTHELLO

What dost thou think?

IAGO

Think, my lord!

OTHELLO

Think, my lord!
By heaven, he echoes me,
As if there were some monster in his thought
Too hideous to be shown. Thou dost mean something:
I heard thee say even now, thou likedst not that,
When Cassio left my wife: what didst not like?
And when I told thee he was of my counsel
In my whole course of wooing, thou criedst 'Indeed!'
And didst contract and purse thy brow together,
As if thou then hadst shut up in thy brain
Some horrible conceit: if thou dost love me,
Show me thy thought.

IAGO

My lord, you know I love you.

OTHELLO

I think thou dost;
And, for I know thou'rt full of love and honesty,
And weigh'st thy words before thou givest them breath,
Therefore these stops of thine fright me the more:
For such things in a false disloyal knave
Are tricks of custom, but in a man that's just
They are close delations, working from the heart
That passion cannot rule.

IAGO

For Michael Cassio,
I dare be sworn I think that he is honest.

OTHELLO

I think so too.

IAGO

Men should be what they seem;
Or those that be not, would they might seem none!

OTHELLO

Certain, men should be what they seem.

IAGO

Why, then, I think Cassio's an honest man.

OTHELLO

Nay, yet there's more in this:
I prithee, speak to me as to thy thinkings,
As thou dost ruminate, and give thy worst of thoughts
The worst of words.
