Posthumus has been humiliated by another man. Instead of directing rage at Iachimo — or examining his own role in the wager — he blames womankind. This is psychologically precise: the man who has failed to protect his marriage now claims women are inherently corrupt. The speech moves from personal betrayal (my wife) to universal law (all women). This is the classic move of misogynist ideology: use one woman's supposed failing to indict all women. The play does not accept this logic. By the end, Posthumus must recant.
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
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, was’t not?
Or less; at first? Perchance he spoke not, but,
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
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,
Nice longing, slanders, mutability,
All faults that man may name, 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
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.
[POSTHUMUS: Translation needed]
[needs modern voice]
[needs emotional core]
The period produced volumes of courtesy books praising female virtue and advocating male respect for women. Posthumus's speech is a violent rejection of that literature. It catalogs vices and assigns them all to women, creating a kind of negative courtesy book. The catalog itself — lying, flattery, lust, ambition, slander — echoes the structure of Renaissance moral philosophy. By mimicking that structure but inverting its conclusions, Posthumus is attempting to create philosophical justification for misogyny. The play's ultimate point is that this justification, however philosophically structured, is built on a lie.
The Reckoning
This is the emotional fallout of 2-4 — the man destroyed by Iachimo's evidence now directs his rage not at the man who deceived him, but at womankind. The speech is relentless and specific: it attributes every vice to women, and it builds from personal betrayal to cosmic misogyny. What makes it psychologically precise is that Posthumus never blames Iachimo or himself. He blames Imogen. And then he blames all women. The speech performs the logic of masculine shame converted into misogynist hatred.
If this happened today…
A man discovers his wife's infidelity and his friend's betrayal. He does not rage at his friend. He does not examine his own part in the wager that created this situation. Instead, he sits down and writes an essay arguing that women are the source of all sin and corruption. His wife in particular. All women generally.
