question: You die and find yourself confronted by two guards at the gates of heaven and hell. You know that one of the guards always tells the truth, and the other always lies. You don't know which is which, and by asking one, and only one, question you need to figure out which one is the gate to Heaven (or hell, if you're adventurous). What will you ask?

answer :If I ask the other guard whether this is the path to heaven, what will he say

The liar is on the path to heaven. If you ask him my question, he knows that the truth teller would answer "yes". So he lies about the answer and says "no".
The liar is on the path to hell. If you ask him, he knows that the truth teller would answer "no", so he lies and says "yes".
The truth teller is on the path to heaven. You ask him the question. He knows that the liar will lie and say "no", so that's what he says.
The truth teller is on the path to hell. He knows that the liar would lie and say "yes", so that's what he says.

so there we have it, im not crazy

untill next time of the Chronicles of Narnia, ja bye bye

here i drew a diagram to help me understand.


question: if i ask the other guy if your path is heaven, what will he say?

Heaven - liar: would say no
- truthful: would say no

Hell - liar: would say yes
- truthful: would say yes

Therefore if the person answers "no", you go on their path.
