The inscriptions may be true or false. Assuming he wants to go to heaven, which door should he take and why ??

LOL - AFAT was one of the first things I looked at too - now for an explanation for Princess :
The inscriptions can be true or false - first step for all Chemical Engineering problems - assume a basis and start solving the problem
.
Let's assume that the first inscription is true - if it is true, then one of the inscriptions is false, and by the basis of the assumption it can only be the other one.
If we assume the the first statement is false we don't get any meaningful result. You can't simply imply from the first statement that one or both are true, because you don't know the basis of the falseness - you anly know there is falsity in the statement. Only one of the 4 basic assumptions yields a definative meaningful result - the others are confuddled.
I will have to get back to you on your new puzzle Lennon
