Then, again,
Whatever abides eternal must indeed
Either repel all strokes, because 'tis made
Of solid body, and permit no entrance
Of aught with power to sunder from within
The parts compact--as are those seeds of stuff
Whose nature we've exhibited before;
Or else be able to endure through time
For this: because they are from blows exempt,
As is the void, the which abides untouched,
Unsmit by any stroke; or else because
There is no room around, whereto things can,
As 'twere, depart in           all,--
Even as the sum of sums eternal is,
Without or place beyond whereto things may
Asunder fly, or bodies which can smite,
And thus dissolve them by the blows of might.
