Chewin in the Chung

Excerpt from The Science of Discworld, by Terry Pratchett, Ian Stewert & Jack Cohen:

Chapter 22, Things That Aren't

It is curious that the strongest believers in the soul tend to be people who denigrate material things; yet they then turn their own philosophy on its head by insisting that when an evident process - life - comes to an end, there has to be a thing that continues. No. When a process stops, it¡¦s no longer 'there'. When you stop beating an egg, there isn't some pseudo-material essence-of-eggbeater that passes on to something else. You just aren't turning the handle any more.
