Act 2, Scene 5

Another room in Philario's house.
Enter Posthumus
Posthumus Is there no way for men to be but women 
Must be half-workers? We are all bastards; 
And that most venerable man which I 
Did call my father, was I know not where 
When I was stamp'd; some coiner with his tools 
Made me a counterfeit: yet my mother seem'd 
The Dian of that time; so doth my wife 
The nonpareil of this. O, vengeance, vengeance! 
Me of my lawful pleasure she restrain'd 
And pray'd me oft forbearance; did it with  10
A pudency so rosy the sweet view on't 
Might well have warm'd old Saturn; that I thought her 
As chaste as unsunn'd snow. O, all the devils! 
This yellow Iachimo, in an hour,--wast not?-- 
Or less,--at first?--perchance he spoke not, but,  15
Like a full-acorn'd boar, a German one, 
Cried 'O!' and mounted; found no opposition 
But what he look'd for should oppose and she 
Should from encounter guard. Could I find out 
The woman's part in me! For there's no motion  20
That tends to vice in man, but I affirm 
It is the woman's part: be it lying, note it, 
The woman's; flattering, hers; deceiving, hers; 
Lust and rank thoughts, hers, hers; revenges, hers; 
Ambitions, covetings, change of prides, disdain,  25
Nice longing, slanders, mutability, 
All faults that may be named, nay, that hell knows,
Why, hers, in part or all; but rather, all;
For even to vice
They are not constant but are changing still 30
One vice, but of a minute old, for one
Not half so old as that. I'll write against them,
Detest them, curse them: yet 'tis greater skill
In a true hate, to pray they have their will:
The very devils cannot plague them better. 35
