You can say that the poison gas is in the false chest. If the gas is indeed in the false chest, the statement is true and the true chest containing the gold will open. If it is false, then the gas is in the true chest and will not be released but the false chest containing the gold will open.

For the bonus riddle: you can say “the chest that opens if I tell lies has the poisonous gas in it.” If the statement is correct, then the truth box will open, giving you the treasure. If the statement is incorrect, the false box will open, giving you the treasure.

[@mathprodigygamer4637]

You could also say, “the box that opens when I say a true statement has the treasure.” If it’s true, then it will open, if it’s false, then the other one will open with the treasure. It’s pretty interesting how you could say lots of different things for something that seems hard.

This should also work with a statement that changes it's truth value after a specific event. Something like "you are holding the paradoxes captive". At first, this is true, so the troll must release the paradoxes. But then the same statement becomes false, so the troll must also release your brother.

[@ZekeRaiden]

Only if he intends to eat the brother _after_ releasing the prisoners. Bit of a problem if he eats your brother _before_ releasing the prisoners.

[@HarmonyGladebloom]

The problem with such statements is that the troll could simply evaluate their truth or falseness once and only release one set of prisoners. Given your example, the troll would say "that's true", and release the paradoxical creatures because you said a true statement, concluding the obligation to its own rules.

[@thenotsomadhatter4291]

That's what I thought, isn't he just breaking his own rules in using this answer?

[@The1stPurpleCat]

It would have to be wrong by definition because the way the video says it works out is that the statement is false, therefore it's true OR it is true therefore it's false. That would lead you (by the rules) to either have the animals and brother eaten, or he just doesn't release either thing.

[@djtrig6576]

It’s only a paradox if he doesn’t release both sides! That’s why it’s coercive logic and how they get away with saying the troll hates paradoxes (as in, he would never refuse to free your brother, as that would make what you said a paradox and he hates them)

[@MasterLoby]

The phrase “you will free my brother” is not a paradoxical statement. Saying “this statement is false” is a paradox, no matter what context your using it in, and is therefore not allowed. The paradox your referring to comes from the rules the troll set up in the first place. “You will free my brother” is conditional paradox that only exists in this type of scenario with the established rules of the choice, and is therefore a non-paradoxical statement that would free both parties.

[@Playzon]

I prefer "you freed my brother." Because of the past tense, the statement is clearly true or false (not both or neither) depending on when you check.

[@Aline-pw1kh]

Me (an intellectual): “you’re green”

[@claytonhoyt6173]

You could also say "You will NOT free the creatures." to the troll. If the statement is true, the troll would have to release the creatures, which he can't do without making the statement paradoxically true and false. The troll's only option is for the statement to be false, forcing it to release the creatures and your brother.

'truth box contains gold'. is the answer because if the statement is correct then truth box will open which has gold. if not it means gold is in false box. so this implies that I said false and false box will open and I get gold.

[@pitpat1682]

I am sorry, but I think it won't work. Because the sentence has no truth value yet (!), like the solution mentioned in the video. The difference is, that in your cause, you have to make the statement right or wrong, not the troll. The troll would have the choice to say: 'That was no statement with a truth value. I will take it as a paradox. ' (Which I would deny, but who am I to argue with a troll?) or he could say: 'No sentence with a truth value yet, I am still waiting for your statement.'

@@pitpat1682 the thing that guy suggested is that troll literally asks you to say "something true" and "something false". Just that words, not false or true statements.

What's in the box there are some cracks, which is what if you where speaking any other language other then English (or just any language where that statement “im in a pickle” has no figurative meaning), but other then that i think your answer is less paradoxical then the one given, seeing as forcing the troll to make a paradox is the same as making a paradox, so he would just keep both.

Can't you just say something like "You learn about nothing in Philosophy"? The statement is true in one sense ("the concept of 'nothing'' is one that is taught in philisophy") And false in another ("You gain no new knowledge by studying philosophy") And it's not a paradox since the two statements rely on seperate readings and therefore don't necessarily conflict with each other. Problem solved.

[@arjunholmie]

interesting point, so of course the riddle is rather vague about this, but your whole trick is to use vagueness to your advantage; I think that doesnt make sense as it doesnt have true propositional meaning. Its as good as saying "chocolates are good", like OK they taste awesome but theyre not usually good for health. At the same time, I'd probably humor this to some extent as a solution, as its not specified that you cant have subjective truths, but yeah Id call it a bit of a cheap shot

[@jeconiahjoelmichaelsiregar7917]

Keep in mind this is a logic puzzle and not an English puzzle. You can't say something whose truth or falseness is self-contradictory, let alone something whose truth or falseness is up for interpretation. In logic, there can only be perfectly true and/or perfectly false statements. While your statement is indeed not a paradox, its truth or falseness isn't clear cut. And the riddle clearly shows us that leaving something up to the Troll's interpretation can backfire. The Troll could simply respond with either "That's true, the subject of nothing is indeed a topic in philosophy" and just free the paradoxes or "That's false, you do learn something new in philosophy" and just release your brother. The key insight here is that you need to say something that isn't just blindly true or false (since you will only end up freeing one party either way), but something that can also dictate the Troll's actions afterwards. That's why the "coercive logic" presented in the riddle is different, in that its truth or falseness, when constrained to the Troll's actions, is surprisingly clear cut. The phrase "You will free my brother" restricts its truthfulness to the Troll's actions, and can only be true since the opposite, by the Troll's own rules, results in a paradox as presented in the video. In a similar fashion, "You won't free the paradoxes" can only be a false statement since if it were true, it also results in a paradox (if the statement is true, the Troll has to release the paradoxes where the statement outlined the opposite), and the Troll will end up releasing both parties. Again, remember, this is a logic puzzle, not a language puzzle. And in logic, there's hardly any in-betweens.

What if you said something random like "there are two chests in front of me", how then do we determine which one will open? And how do we determine what is inside that chest? I would think the true chest would open (because I am standing in front of two chests) but that doesn't tell us what would come out of it. And even if my statement was interpreted to be false (maybe I am also standing in front of gold and poison in addition to two chests), this doesn't tell us what is in side of the false chest.

But in the case of "The true chest contains the gold", since both words "gold" and "true chest" are included it makes it work.

[@slikshot6]

@@Pablo-ob2bx Yea I was thinking how I would play this scenario out in my mind and I realized that if I couldn't control where the gold or poison was then it was truly random. Thanks for replying I just needed to bounce that question off of someone.

[@avainbaxter9318]

What if both chests open.

[@dijkkla9948]

I got the riddle but misinterpreted the rules. The awnser is a paradox, and the troll will do anything to avoid those. But I understood it like: "The troll will not release either the creatures or your brother, because it hates paradoxes, and will not cooperate if you state one." As for the bonus riddle... I'm gonna state the rules as I understand them: - You can only say one statement. - The statement must be true or false. (It may be both but then you'll die anyway ;) - One chest opens if you say a true statement, the other will open if the statement is false. - You do NOT know which chest opens by what stament. - You cannot refer to the chests like: "The chest that opens by a true statement contains the tressure." Because you do not know which chest reacts to which. (Kinda weird but my interpretation.) - You do NOT have to know yourself if your statement is true or false. (Again, my interpretation.) Does anyone know, and is able to explain, what the awnser is/would be, or if the rules I stated are incorrect (making it impossible)? EDIT: I've seen many solutions like: "The poison gas is in the false chest." and "The treasure is in the statement right chest." but is it possible to solve it any other way? It just seems so easy...

[@combogalis]

You were correct in your original interpretation of the first riddle. The troll would not cooperate if we'd said a paradox such as "This statement is false," because it hates paradoxes. Saying "you will free my brother" is not a paradox. What we did was force the troll to release both in order to avoid a paradox. As for the bonus riddle, what makes you say the fifth rule you listed is a rule? The video never says that you can't do that. That is the answer. You say "The false chest contains the poison gas," and that way if it's true, the true box opens and gives you the treasure, and if it's false, the false box opens and gives you the treasure.

[@thetri-bdojel2220]

It seems easy but it's a valid answer. You have to state an answer that's true if the treasure is in the true chest, and false if it's in the false chest. The only way you can do that is by having the location of the treasure determine wether the answer is true.

[@combogalis]

@@TheCLBrown If the answer is false, then he has to release his brother, since that was the condition. Dijkkla, I just saw your edit. If your complaint is that it's easy, that's because it is easy. It is especially easy because it's basically the same as the first riddle. There is no other solution.

Technically at the time you said that statement, it false. So it only applies at that point in time.

The answer is not a paradox.

[@MysticLuster]

The statement "you will release my brother" would only be a paradox if the troll made your statement false by refusing to release your brother, because then he would have to release your brother which would make your statement true. This makes your statement a potential paradox, not an actualized paradox. Since the troll hates paradoxes, he will avoid making a paradox, by making your statement true.
