Puzzle: The Two Doors and the Two Doorkeepers: How to Get to Heaven?

A man who was was good to his neighbors but wasn't a believer in God died and was standing before the Pearl Gate. Peter, who had the keys, according to this story, said to him: "Son, you have been good to your neighbors and so you are given an opportunity to find out your way into heaven. Remember you have only one chance.

1. There are two doors. One of them is a door to heaven and another is a door to hell.
2. In front of each door, there is a doorkeeper.
3. One of the doorkeepers always speaks the lie; the other always speaks the truth.
4. You have to ask only one question to either one of them, and decide which door you will enter through.

What question will he ask? Note: he doesn't know which door leads to hell or to heaven and he also doesn't know who is the liar and who is true.


If the answer is tooooo difficult, scroll down...........................









































































































Answer:
He will ask to any one of them "What will the other doorkeeper say if I ask him the way to heaven?" and then enter into the opposite door.
1. If he goes to the liar and asks the question, the liar will tell a lie and show the false door; which means that he has to enter its opposite, the true one.
2. If he goes to the true one and asks the question, he will tell the truth and show the same false door that the liar is going to show; which means that he has to enter its opposite, the true one.

    I think they need to add a little more info. I assumed the door to heaven was the truthful one and I figured to ask one of them how many fingers are u holding up. Its and obvious question so if they lie their is the door to hell.

Placebo and the Philosophy of Mind and Matter in Drug Research

A placebo is a non-therapeutic substance administered under the camouflage of medication to deceive patients into believing that they are receiving medications; this done solely for psychological and not for physiological effects. Placebo may usually be used to compare its effects with the effects of other drugs in drug research. Let's take the case of an experiment that tries to establish whether a particular drug, say to treat weariness, is genuine or merely has the effects of a placebo. Suppose 20 candidates are chosen for this experiment. 10 are given the drug and the rest are put on a placebo while they are told that the placebo is a genuine medication. They need to make sure that the deception is well carried on for the success of the experiment. If both the groups make similar improvements after taking the treatments, the new drug seems to only function as a placebo in effect. The basic hypothesis of the placebo raises the question of mind over matter. Of course, this pushes...

3 Facts About Temptation

M...L...S 1. Temptation is MOMENTARY. It won't last forever. The devil tries to make it look as the final reality. But, it is not. It is just a test, and it'll be over; but, the question is whether you'll pass it. 2. Temptation is a Test of LOVE; and LOVE is an action. Love fulfills all the commandments. The two greatest are LOVE GOD with all your being and LOVE YOUR NEIGHBOR as yourself. But, love is not a feeling or emotion; it is an action. We need to LOVE Him more in the moment of temptation; it can only be possible when we focus on Him. 3. Temptation will make you STRONGER and PURER. It may stretch your muscle; but, not beyond your capacity; and then the HELPER, our TRAINER is there with us and knows what will make us stronger... Despite all this, let us never forget to pray: "Lead us not into temptation, but deliver us from the evil one!"

The Light of Law Vs Light of Christ (John 8)

JOHN 8:1-12 Jesus went unto the mount of Olives. And early in the morning he came again into the temple, and all the people came unto him; and he sat down, and taught them. And the scribes and Pharisees brought unto him a woman taken in adultery; and when they had set her in the midst, They say unto him, Master, this woman was taken in adultery, in the very act. Now Moses in the law commanded us, that such should be stoned: but what sayest thou? This they said, tempting him, that they might have to accuse him. But Jesus stooped down, and with his finger wrote on the ground, as though he heard them not. So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her. And again he stooped down, and wrote on the ground. And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the mids...
