A Smullyan Puzzle from Jim Henson’s Labyrinth

While trying to navigate her way through the Labyrinth, Sarah finds two doors protected by two different guards.  The guards inform Sarah that one door leads to the castle at the center of the labyrinth while the other leads to… dah-dah-doom… certain death!  The guards explain that she can only ask one guard one yes-or-no question.  Furthermore, one of the guards always tells the truth and the other always lies.  What should she ask the guard in order to know which door to choose?

Be the first to answer correctly and win the prize of selecting the next philosoraptor theme!

[UPDATE] Congrats to Andy V, who quickly dispatched of the riddle.  If you were lost in a labryrinth haunted by David Bowie, you’d want Andy to be your guide!  I am awaiting a theme from him.

Here is the clip from the movie.

  1. She should ask the guard, “will the other guard tell me your path leads to the castle?”

  2. Indeed Andy. Name your theme!

  3. Derrida! (or I’ll take postmodernism in general to make your life easy)
