This is a logic question and can be answered if one realizes that the TRUTH of a LIE is a LIE, and the LIE of a TRUTH is a LIE. You need one guard to give you the other guard’s answer. Knowing this one could ask a question like, “If I were to ask the other guard which door leads to paradise, what would he say?”
If you ask the guard who always tells the truth, he would tell you the other guard would point you to the gate of hell.If you ask the guard who always lies, he would tell you the opposite door of the truth-telling guard and point you to the gate of hell.In either case, both guards will point to the door of death so you should choose the other one.

Pardon?
Okay, I needed to reread that like a dozen of times, but I think I'm getting it...
Wow! I have a headache, guiding! LOL
Awesome, Guiding!!
The guy who runs a local cafe gave me a lateral thinking puzzle today (that I couldn't do) and so I gave him the 2 doors puzzle.
Here's his solution: Ask them what is 5+2. The one who says the wrong answer is the demon guarding hell!
Simple but effective - and not the one anyone with a philosophical bent would expect.
Wow to guiding light81's response!
