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.)
What if the prisoner were thinking about it in the afternoon on thursday?
For the purposes of the problem, to be surprised just means that something happened to you which you didn't predict beforehand.
Okay, I understand that.
Its not the usual definition (among other things it implies I should be 'surprised' if a coin I flip comes up heads) but presumably whoever first came up with the paradox couldn't think of a better word to express whatever they meant.
But I don't understand that.
I mean, why couldn't I simply predict that it would be heads or tails?
Then wouldn't the prisoner be surprised no matter what?
But, wait, when exactly are we judging whether he's surprised?
Let's say that it's thursday in the afternoon, and he's sitting around saying to himself, "I'm totally surprised that it's going to come on friday. I was online reading about this exact situation, and I thought that it couldn't come on friday, because it would be the last available day, and I would know that it would be coming." Or are we waiting for that surprise to dissipate, and turn into "well, I guess that I'm going to di... (read more)
Sure, you would be surprised that you were about to die now.
But would you also be surprised that your life didn't end up being eternal? No, because you know that you will die someday.
But what's the significance of this distinction for this problem? Well, I don't understand how the prisoner could think anything other than, "I guess that I'm going to end up dead one of these days around noon (monday, tuesday, wednesday, thursday, or friday)." It's not like he has any reason to think that it would be more likely to happen one of the days rather than... (read more)
I'm totally confused.
Why would anybody in that situation ever be surprised?
I mean, they would know that somebody will execute them at noon on one of the days (monday, tuesday, wednesday, thursday, or friday). No matter what day it come on, why would they be surprised? If it comes at noon on monday, they would think, "Oh, it's noon on monday, and I'm about to die; nothing surprising here." If it doesn't come at noon on monday, they would think, "Oh, it's noon on monday, and I'm not about to die; nothing surprising here (I guess that it will come on one of the other days)." Or whatever.
(Assuming that the the warden told the truth, and the prisoner assumed that.)
That's my understanding of what I value, at least.
Well, I'm not so sure that those words (the ones that I used to summarize your position) even mean anything.
How could you value them wanting to kill you somewhat (which would be you feeling some desire while cycling through a few different instances of imagining them doing something leading to you dying), but also value you not dying even more (which would be you feeling even more desire while moving through a few different examples of imagining you being alive)?
It would be like saying that you value goi... (read more)
Good point.
