I'm not a very smart person, and never studied philosophy at school or college. I've been reading Discworld books since I was a wee little person and even though I've pretty thoroughly absorbed the messages to the best of my understanding, I'm sure there's lots I've missed.

I know this question has a bit of complexity in it, as someone like Vimes believes different things to the Patrician, or Granny Weatherwax, or Brutha, or Death.

Still, I feel like there might be something that links it all together and was wondering if anyone smarter than me might know?
