For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow
- Ecclesiastes 1:18 (KJV)
3 – Infinite Names and Infinite Faces
Humans said that ignorance was bliss. When he'd first heard that, he hadn't understood it; he longed to know more about the universe, as much as he could find out.
He understood it now.
He could feel the turn of the Earth, could see all that is, all that was, all that could ever be. He could see it all, stored inside his head along with all of the names and faces that he had seen and heard along the way, from his granddaughter to Rose.
That's what he saw, all of the time.
And it just drove him mad.
