On highly punitive religion and society:
Borvorius produced a flask from somewhere.
"Will you go to hell if you have a drop of spirit?" he said.
"So it seems," said Simony, absently. Then he noticed the flask. "Oh, you mean alcohol? Probably. But who cares? I won't be able to get near the fire for priests. Thanks."
"Small Gods" is a fun read. There's a metaphor involving sheep and goats that by itself makes the book worthwhile. I'd recommend it to you, but you've probably already read it. (Ben has; he's the one who convinced me to read it.) I'm sadly behind the times when it comes to Terry Pratchett.
