| 2024-05-13 21:28:22 +0200 | <monochrom> | Right? We know of escape rooms that are way more logical than the lunatic. :) |
| 2024-05-13 21:27:04 +0200 | <monochrom> | For the lunatic case, I may consider adding the simulation hypothesis and say that I'm in a simulation, not the least because why else there is lunatic targetting me, so I open both boxes to ensure efficient end of the simulation. >:) |
| 2024-05-13 21:25:26 +0200 | <ncf> | in other words, logic puzzles are not a survival manual |
| 2024-05-13 21:24:44 +0200 | <int-e> | ncf: ah. how long has... oh god. |
| 2024-05-13 21:24:37 +0200 | <monochrom> | In the same way the sentinel puzzle begins with "you don't know whether he's honest or lying but it is one of them". |
| 2024-05-13 21:24:19 +0200 | <ncf> | if you refuse to read the inscriptions there is no puzzle |
| 2024-05-13 21:24:11 +0200 | <ncf> | we've been over this <ncf> the hidden piece of information is that both sentences are meaningful |
| 2024-05-13 21:23:49 +0200 | <tomsmeding> | it draws a conclusion from the inscriptions |
| 2024-05-13 21:23:47 +0200 | <int-e> | the inscription could be meaningless |
| 2024-05-13 21:23:46 +0200 | <monochrom> | It begins with someone who makes sure that each sentence is honest or lying. |
| 2024-05-13 21:23:34 +0200 | <tomsmeding> | mauke: the article does not draw a conclusion about the caskets |
| 2024-05-13 21:23:10 +0200 | <mauke> | because the gold inscription is false |
| 2024-05-13 21:23:05 +0200 | <mauke> | in the original puzzle, you know that at least one inscription does not apply to reality |
| 2024-05-13 21:23:03 +0200 | <monochrom> | But the casket logic puzzle does not begin with someone who is a violent lunatic who gates my guts. |
| 2024-05-13 21:23:01 +0200 | <tomsmeding> | it just claims that it is the logical conclusion of the inscriptions |
| 2024-05-13 21:22:54 +0200 | <tomsmeding> | the article does not claim that the portrait is _actually_ in that casket |
| 2024-05-13 21:22:37 +0200 | <tomsmeding> | whether the conclusion applies to reality is then predicated on whether you believe that the inscriptions apply to reality |
| 2024-05-13 21:22:35 +0200 | <mauke> | yes, but what good will that do you? |
| 2024-05-13 21:22:21 +0200 | <tomsmeding> | mauke: you can still do logic on the inscriptions |
| 2024-05-13 21:21:22 +0200 | <mauke> | which box do you open? |
| 2024-05-13 21:21:18 +0200 | <mauke> | also, there are inscriptions on the boxes or whatever |
| 2024-05-13 21:21:11 +0200 | <mauke> | I am a violent lunatic who hates your guts. I have trapped you in a locked room. In the room, there are two boxes. One of them contains a key that lets you out, the other contains a bomb that goes off when you open the box and blows you to bits. |

| 2024-05-13 21:19:58 +0200 | <mauke> | I think I need to reformulate this problem a bit |
| 2024-05-13 21:18:49 +0200 | <ncf> | mauke: if i were to formalise this in, say, Agda, i would postulate that there is a boolean type Casket = gold | silver, a predicate HasPainting : Casket → DecProp such that HasPainting(gold) ∨ HasPainting(silver), a DecProp Gold such that Gold ≃ ¬HasPainting(gold), and a DecProp Silver such that Silver ≃ ExactlyOne Gold Silver, and then proceed to show that HasPainting(gold) holds |
| 2024-05-13 21:18:16 +0200 | <tomsmeding> | it clearly threw mauke off |

| 2024-05-13 21:18:08 +0200 | <tomsmeding> | which is admittedly unrelated, but at the level of preciseness that you need in such a context |
| 2024-05-13 21:17:51 +0200 | <tomsmeding> | there is the implicit "the" |
| 2024-05-13 21:17:38 +0200 | <monochrom> | Yeah there is the assumption that this self-reference has a solution. |
| 2024-05-13 21:15:45 +0200 | <tomsmeding> | although I agree that if you start writing self-referential sentences, you better be damn clear about what exactly you mean |
| 2024-05-13 21:15:26 +0200 | <tomsmeding> | this discussion was about interpreting the puzzle's text too literally so that you miss the point of the puzzle |
| 2024-05-13 21:14:56 +0200 | <tomsmeding> | I don't think this discussion was about that :) |
| 2024-05-13 21:14:36 +0200 | <monochrom> | But I guess I am speaking to a community that even refuse to use booleans for logic at all. |
| 2024-05-13 21:14:11 +0200 | <monochrom> | I was just hoping to show that it is beautiful that boolean (==) makes a monoid. |
| 2024-05-13 21:13:50 +0200 | <mauke> | no, a continuum hypothesis |

| 2024-05-13 21:13:47 +0200 | <ncf> | "this sentence is true" denotes a fixed point of the identity. in classical logic there are two: true and false |
| 2024-05-13 21:13:24 +0200 | <ncf> | do i need to slap you with a fixed point |
| 2024-05-13 21:13:06 +0200 | <mauke> | they are the same world |
| 2024-05-13 21:12:55 +0200 | <ncf> | both worlds are possible |
| 2024-05-13 21:12:50 +0200 | euleritian | (~euleritia@dynamic-176-006-186-214.176.6.pool.telefonica.de) |
| 2024-05-13 21:12:49 +0200 | <ncf> | it can be either |
| 2024-05-13 21:12:47 +0200 | <ncf> | its' not both true and false |
| 2024-05-13 21:12:37 +0200 | <mauke> | "who cares" is not a truth value |
| 2024-05-13 21:12:30 +0200 | <mauke> | in one case, the silver inscription is neither true nor false (paradox), in the other, the silver inscription is both true and false |
| 2024-05-13 21:12:29 +0200 | <tomsmeding> | two possible universes, but the solution of where the portrait is doesn't depend on that choice |
| 2024-05-13 21:12:13 +0200 | <tomsmeding> | there are -- gold is false, silver is either true or false |
| 2024-05-13 21:12:05 +0200 | <ncf> | yes: portrait in gold casket, gold casket lying, silver casket who cares |
