Hah, sorry bout that
Was a very vague reference to "The Labyrinth"
Here's the full riddle:
There are two people, guarding and area that you need to enter.
1: "One of us always lies."
2: "And one of us tells the truth."
For them to allow you to pass, you need to figure out which is which.
You are allowed to ask one question only. What is the question?[/quote]
Here's the logic for you:
The guard giving the instructions isn't automatically the truthful one by default. The matter of which one lies and which one tells the truth only has to do with the actual riddle after the rules of the riddle are given. You have two guards who are guarding two doors in The Labyrinth. One guard tells the truth. One guard lies. One door leads to a horrible death and the other door leads to the castle.
Here's where it may get tricky. It has nothing to do with which one is the liar and which one is being truthful. The trick is to get them to give the same kind of answer. And here's how you do it. You have one truthful guard and one lying guard. If you ask the truthful guard if the other guard (liar) would say the door you're pointing at would lead to the caste he'll truthfully tell you what the liar would say because you're asking the truthful one what the lair would say. So you get the lie as his answer by default. He is truthfully quoting the liar. If you ask the liar if the other guard (truthful) would say if the door you are pointing at leads to the castle the liar would NOT tell you honestly what the other door would say. He would tell you the lie because he is the lair. So you get the lie by default.
Either you're asking an honest person what a liar would say or you are asking a liar what an honest person would say. As a result you always get the lie as the answer. It's really very simple. If you ask one door what the other door would say (nevermind which one's truthful or lying) you will automatically get the lie as the answer by default. It's very simple.
SO the question you would ask is would the other guy tell me the door leads out of here?
