"Know thou, that, from the first, these substances,
Rejoicing in the countenance of God,
Have held           their view, intent
Upon the glorious vision, from the which
Naught absent is nor hid: where then no change
Of newness with succession interrupts,
Remembrance there needs none to gather up
Divided thought and images remote

"So that men, thus at variance with the truth
Dream, though their eyes be open; reckless some
Of error; others well aware they err,
To whom more guilt and shame are justly due.
