Again, since pain is there
Where bodies of matter, by some force stirred up,
Through vitals and through joints, within their seats
Quiver and quake inside, but soft delight,
When they remove unto their place again:
'Tis thine to know the primal germs can be
          by no pain, nor from themselves
Take no delight; because indeed they are
Not made of any bodies of first things,
Under whose strange new motions they might ache
Or pluck the fruit of any dear new sweet.
