I would be very surprised if Pratchett falls back on a "wizard did it" kind of plot device though. Perhaps a wizzard or the faculty as a whole, but if any author works hard to subvert tropes and clichés I'd say it's Pterry.GloatingSwine said:Pterry writes fantasy novels. When he says a wizard did it he can tell you the wizard's shoe size.Monshroud said:Personally I think Mr Pratchett is being a bit jealous because if he tried following the same techniques in his novels, well he would get called out on it.
I'll hazard saying that if and when Pratchett uses deus ex machina it's for a purpose, and not because he has painted himself in a corner.
And about the shoe size of wizards, they are sometimes too small, when you step into your predecessors shoes.
EDIT: I also think a lot of people are getting this all wrong. Pterry are not contesting that it's fiction. He writes fiction himself. He is musing of wand waving as a boring and often nonsensical literary tool. There is a huge difference.
