Oth. Certaine, men should be what they seeme

Iago. Why then I thinke Cassio's an honest man

Oth. Nay, yet there's more in this?
I prythee speake to me, as to thy thinkings,
As thou dost ruminate, and giue thy worst of thoughts
The worst of words

Iago. Good my Lord pardon me,
Though I am bound to euery Acte of dutie,
I am not bound to that: All Slaues are free:
Vtter my Thoughts? Why say, they are vild, and falce?
As where's that Palace, whereinto foule things
Sometimes intrude not? Who ha's that breast so pure,
Wherein vncleanly Apprehensions
Keepe Leetes, and Law-dayes, and in Sessions sit
With meditations lawfull?
Oth. Thou do'st conspire against thy Friend (Iago)
If thou but think'st him wrong'd, and mak'st his eare
A stranger to thy Thoughts

Iago. I do beseech you,
Though I perchance am vicious in my guesse
(As I confesse it is my Natures plague
To spy into Abuses, and of my iealousie
Shapes faults that are not) that your wisedome
From one, that so imperfectly conceits,
Would take no notice, nor build your selfe a trouble
Out of his scattering, and vnsure obseruance:
