[quote1233604321=Telos]
You are proceeding out of limbo and face two doors, one to heaven and one to hell. There are attendants at each door, and one always lies, and the other always tells the truth. You can ask one inquiry type question of one attendant to ensure you identify the right door. What question do you come up with and why?
[/quote1233604321]
I would ask them something about myself. Like, is my hair blonde, etc.
But I'm guessing this is assuming I am a completely objective entity? I have no relevance in the puzzle other than which door I go through and what question I ask.
In that case, if I asked either attendant "which door would the other attendant say is the door to heaven,"
Heav|Hell
Truth|Lie
The honest attendant guarding heaven would tell me the door on the right, because the dishonest one would lie. The dishonest one would do the same because he would lie about what the honest one would say. And then of course you could switch it.
