Isn't that exactly what we do here (and on other forums)?
Wasn't that line (the one saying that the hangman comes for him on wednesday) just supposed to be an example? I didn't think that the problem required the hangman to come on wednesday; I thought that it left open when he would actually come.
(And, no, I'm definitely not making fun of you.)
Wait, why on wednesday?
What about if the prisoner is still alive on thursday in the afternoon?
the warden was correct in the end
Where?
Oh okay.
No, but I can accurately predict that a coin will come heads or tails.
Oh, I see.
At first, I missed the significance of this passage:
The warden's statement is then false and unparadoxical. This is similar to the one-day analogue, where the warden says "You will be executed tomorrow at noon, and will be surprised" and the prisoner says "wtf?".
Then here's an analogous "paradox":
So, yeah, that's why I said that it sounds like a garden variety contradiction.
Good point.
