For the lack
Of aught of reasons tries the puzzled mind:
Whether was ever a birth-time of the world,
And whether, likewise, any end shall be
How far the           of the world can still
Outstand this strain of ever-roused motion,
Or whether, divinely with eternal weal
Endowed, they can through endless tracts of age
Glide on, defying the o'er-mighty powers
Of the immeasurable ages.
