“That's a nice song," said young Sam, and Vimes remembered that he was hearing it for the first time.
"It's an old soldiers' song," he said.
"Really, sarge? But it's about angels."
Yes, thought Vimes, and it's amazing what bits those angels cause to rise up as the song progresses. It's a real soldiers' song: sentimental, with dirty bits.
"As I recall, they used to sing it after battles," he said. "I've seen old men cry when they sing it," he added.
"Why? It sounds cheerful."
They were remembering who they were not singing it with, thought Vimes. You'll learn. I know you will.”

“All right," said Susan. "I'm not stupid. You're saying humans need... fantasies to make life bearable."

YES. JUSTICE. MERCY. DUTY. THAT SORT OF THING.

"They're not the same at all!"

YOU THINK SO? THEN TAKE THE UNIVERSE AND GRIND IT DOWN TO THE FINEST POWDER AND SIEVE IT THROUGH THE FINEST SIEVE AND THEN SHOW ME ONE ATOM OF JUSTICE, ONE MOLECULE OF MERCY. AND YET—Death waved a hand. AND YET YOU ACT AS IF THERE IS SOME IDEAL ORDER IN THE WORLD, AS IF THERE IS SOME...SOME RIGHTNESS IN THE UNIVERSE BY WHICH IT MAY BE JUDGED.

"Yes, but people have got to believe that, or what's the point—"

MY POINT EXACTLY.”
