Now there's an interesting question - what's the prior probability that you're actually in a play? Is it even answerable, when all knowledge you're allowed to have is fully controlled? Is it even worth bothering to think about, when (under this hypothesis) all of your thoughts are controlled by an author? All of which dodges the principle issue - do you really think Rosencrantz and Guildenstern are actually sentient, in any sense?
