John Donne - Negative Love

I never stoop'd so low, as they
Which on an eye, cheek, lip, can prey,
Seldom to them, which soar no higher
Than virtue or the mind to admire,
For sense, and understanding may
Know, what gives fuel to their fire:
My love, though silly, is more brave,
For may I miss, when ere I crave,
If I know yet, what I would have.

If that be simply perfectest
Which can by no way be exprest
But Negatives, my love is so.
To All, which all love, I say no.
If any who deciphers best,
What we know not, our selves, can know,
Let him teach me that nothing; This
As yet my ease, and comfort is,
Though I speed not, I cannot miss.

John Donne
