John Donne

The Flea

The argument structure

Donne uses a flea as a logical proof—if the flea can mix their blood without sin, why can't they? This is a **reductio ad absurdum** meant to dismantle her objections through wit rather than emotion.

Mark but this flea, and mark in this,
How little that which thou deniest me is;
It suck'd me first, and now sucks thee,
And in this flea our two bloods mingled be.
Thou know'st that this cannot be said
A sin, nor shame, nor loss of maidenhead;
{{gap|1em}}Yet this enjoys before it woo,
{{gap|1em}}And pamper'd swells with one blood made of two;
{{gap|1em}}And this, alas! is more than we would do.
O stay, three lives in one flea spare,

Three lives claimed

Donne counts: the flea's life, hers, and his. This theological precision matters—he's building a case that killing the flea is murder (of three souls), making her resistance look absurd.

Where we almost, yea, more than married are.

Marriage language weaponized

Notice he calls the flea a 'marriage bed' and 'marriage temple'—he's using religious/legal language for sexual union to reframe what she's denying him as already legitimized.

This flea is you and I, and this
Our marriage bed, and marriage temple is.
Though parents grudge, and you, we're met,
And cloister'd in these living walls of jet.
{{gap|1em}}Though use make you apt to kill me,
{{gap|1em}}Let not to that self-murder added be,
{{gap|1em}}And sacrilege, three sins in killing three.
Cruel and sudden, hast thou since

She kills the flea

The poem pivots here—she's actually killed it between stanzas 2 and 3. Donne shifts from pleading to using her own action against her argument.

Purpled thy nail in blood of innocence?
Wherein could this flea guilty be,
Except in that drop which it suck'd from thee?
Yet thou triumph'st, and say'st that thou
Find'st not thyself nor me the weaker now.
{{gap|1em}}'Tis true; then learn how false fears be;
{{gap|1em}}Just so much honour, when thou yield'st to me,
{{gap|1em}}Will waste, as this flea's death took life from thee.

Reading Notes

How the poem works as seduction argument

This is not a love poem—it's a logical trap disguised as flattery. Donne takes an insignificant object (a flea) and builds an elaborate three-stanza argument: (1) the flea has mixed their blood without sin, so why can't they? (2) killing the flea would be murder of three souls, so don't; (3) she kills it anyway, proving her fears were false, so his point stands.

The genius is structural. Each stanza raises the stakes of the argument. In stanza 1, he's asking her to see the flea as innocent evidence. In stanza 2, he's making killing it seem like a moral crime. In stanza 3, she's already killed it—and he uses her own action as proof that nothing bad happens. The poem doesn't try to convince through emotion; it convinces through logical inevitability.

This is characteristic of Donne's metaphysical wit—taking an absurd premise (a flea as marriage) and following it to its rational conclusion with perfect seriousness. The humor comes from watching him argue so precisely about something so ridiculous.

Why this matters historically

CONTEXT This poem was written around 1590s England, when women's sexual resistance was legally and religiously enforced. Donne's speaker isn't being romantic—he's using intellectual firepower to dismantle her stated objections.

What's radical here is that he never appeals to her desire or his love. Instead, he attacks her logic. He doesn't say "I love you"—he says "Your fear is mathematically baseless." This was Donne's innovation: using scholastic argument (the method of university theology) to seduce. It's seduction by syllogism.

The poem also reveals something about Donne's world: that women's refusal was framed as fear-based irrationality rather than autonomous choice. By "proving" her fears false, he's not actually winning consent—he's performing intellectual dominance. The poem is brilliant precisely because it shows how wit can be a tool of persuasion that bypasses actual agreement.
