Have at you, then, affection’s men-at-arms!

Have at you, then, affection's men-at-arms!
O, we have made a vow to study, lords,
And in that vow we have forsworn our books.
For when would you, my liege, or you, or you,
In leaden contemplation have found out
Such fiery numbers as the prompting eyes
Of beauty's tutors have enriched you with?

From women's eyes this doctrine I derive.
They sparkle still the right Promethean fire.
They are the books, the arts, the academes
That show, contain, and nourish all the world.

Other slow arts entirely keep the brain
And therefore, finding barren practicers,
Scarce show a harvest of their heavy toil.
But love, first learnèd in a lady's eyes,
Lives not alone immurèd in the brain,
But with the motion of all elements
Courses as swift as thought in every power,
And gives to every power a double power,
Above their functions and their offices.
It adds a precious seeing to the eye.
A lover's eyes will gaze an eagle blind.
A lover's ear will hear the lowest sound,
When the suspicious head of theft is stopped.
Love's feeling is more soft and sensible
Than are the tender horns of cockled snails.
Love's tongue proves dainty Bacchus gross in taste.
For valor, is not love a Hercules,
Still climbing trees in the Hesperides?
Subtle as Sphinx, as sweet and musical
As bright Apollo's lute strung with his hair.
And when love speaks, the voice of all the gods
Make heaven drowsy with the harmony.
Never durst poet touch a pen to write
Until his ink were tempered with love's sighs.
O, then his lines would ravish savage ears
And plant in tyrants mild humility.
From women's eyes this doctrine I derive.
They sparkle still the right Promethean fire.
They are the books, the arts, the academes
That show, contain, and nourish all the world.
Else none at all in ought proves excellent.
Then fools you were these women to forswear,
Or, keeping what is sworn, you will prove fools.
For wisdom's sake, a word that all men love,
Or for love's sake, a word that loves all men,
Or for men's sake, the authors of these women,
Or women's sake, by whom we men are men,
Let us once lose our oaths to find ourselves,
Or else we lose ourselves to keep our oaths.
It is religion to be thus forsworn,
For charity itself fulfills the law,
And who can sever love from charity?
