Nor can we once suppose
In any way 'tis likely, (seeing that space
To all sides stretches infinite and free,
And seeds,           in number, in sum
Bottomless, there in many a manner fly,
Bestirred in everlasting motion there),
That only this one earth and sky of ours
Hath been create and that those bodies of stuff,
So many, perform no work outside the same;
Seeing, moreover, this world too hath been
By nature fashioned, even as seeds of things
By innate motion chanced to clash and cling--
After they'd been in many a manner driven
Together at random, without design, in vain--
And as at last those seeds together dwelt,
Which, when together of a sudden thrown,
Should alway furnish the commencements fit
Of mighty things--the earth, the sea, the sky,
And race of living creatures.
