logical deduction – Two doorways with two guards – one lies, one tells the reality


Here’s a twisted answer.

Go to any guard, level at a door and ask:
Among the many propositions 1. “You’re a liar”, 2. “You’ll reply negatively” and three. “This door results in freedom”, is there an odd variety of true propositions?

Should you get the reply sure:
If the guard is a truthteller, the variety of truths is odd, 1. is fake, 2. is fake, so 3. have to be true.
If the guard is a liar, the variety of truths is even, 1. is true, 2. is fake, so 3. have to be true.

Should you get a detrimental reply:
If the guard is a truthteller, the variety of truths is even, 1. is fake, 2. is true, so 3. have to be true.
If the guard is a liar, the variety of truths is odd, 1. is true, 2. is true, so 3. have to be true.

So whatever the reply of the guard, the door you pointed at is the door to freedom, you possibly can depart safely.
