Oh my.

Sarah, of course, is a bright young woman, and makes short work of the Guardians in their attempts to confuse her.
matched
As John Touri points out in the paper Objective Falsity is essential to lying, an argument from convergent evidence published in Philosophy Studies in twenty twenty one, she engages in what is called answer laundering.
matched
If Sarah simply asked one of the guards which door was which, then it might be a true or untrue statement that she gets in return, and her chances therefore are no better than simply picking a door at random.
matched
Instead, she launders one answer through another.
matched
Turi explains, quote, by asking one guard whether the other guard would say that this door leads to success, Sarah deduced the correct one.
matched
Either she gets the truth about a lie or a lie about the truth.
matched
Whenever she is told yes, the correct answer is no, and whenever she is told no, the correct answer is yes.
matched
The truth and the lie dependably cancel each other out in this scenario, provided Touri stresses that lies cannot be true.
matched
Turi points out that the riddle of the four guards is a variant of the Knights and Knaves logic puzzle from Raymond Smollian's 1978 publication, What is the Name of This Book?
matched
The scenario in the book that closely resembles the scene from Labyrinth involves a knight and a knave, otherwise indistinguishable, who guard a fork in the road.
matched
Which road do you take?
matched
Dare you ask these two men given that one is secretly a noble knight, and the other secretly a vile knave?
matched
Only one of them is going to give you a good answer, the other one is going to lie to you.
matched
The solution again comes via answer laundering.
matched
Ask which path the other individual would say is the correct one.
matched
So this is how the four guards of Labyrinth work.
matched
Unless I am lying, which I am not.
matched
Alright, let's keep the labyrinth fires burning with the fieries of labyrinth.
matched
I know you remember these guys.
