Lucretius, De Rerum Natura
William Ellery Leonard, Ed.

     But if one say that sense can so far rise
From non-sense by mutation, or because
Brought forth as by a certain sort of birth,
'Twill serve to render plain to him and prove
There is no birth, unless there be before
Some formed union of the elements,
Nor any change, unless they be unite.
     In first place, senses can't in body be
Before its living nature's been begot,-
Since all its stuff, in faith, is held dispersed
About through rivers, air, and earth, and all
That is from earth created, nor has met
In combination, and, in proper mode,
Conjoined into those vital motions which
Kindle the all-perceiving senses- they
That keep and guard each living thing soever.
     Again, a blow beyond its nature's strength
Shatters forthwith each living thing soe'er,
And on it goes confounding all the sense
Of body and mind. For of the primal germs
Are loosed their old arrangements, and, throughout,
The vital motions blocked,- until the stuff,
Shaken profoundly through the frame entire,
Undoes the vital knots of soul from body
And throws that soul, to outward wide-dispersed,
Through all the pores. For what may we surmise
A blow inflicted can achieve besides
Shaking asunder and loosening all apart?
It happens also, when less sharp the blow,
The vital motions which are left are wont
Oft to win out- win out, and stop and still
The uncouth tumults gendered by the blow,
And call each part to its own courses back,
And shake away the motion of death which now
Begins its own dominion in the body,
And kindle anew the senses almost gone.
For by what other means could they the more
Collect their powers of thought and turn again
From very doorways of destruction
Back unto life, rather than pass whereto
They be already well-nigh sped and so
Pass quite away?
     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
Assaulted 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.
And so they must be furnished with no sense.
