IV.3
...
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 stopp'd: 
And when Love speaks, the voice of all the gods 
Makes heaven drowsy with the harmony.
Never durst poet touch a pen to write
Until his ink were temper'd 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?
