My postings have been a bit depressing recently so I thought a little Smullyanesque/Newheiseran Logic puzzles might relieve the tension.
You've died and are strolling through purgatory on your way to Heaven.
Now in order to get to heaven you must climb many hundreds of flights of stone stairs,
But in front of each staircase stand three individuals who will not let you pass them by;
unless you identify their true nature :
Each time all three look human , But One is an Angel who always tells the truth, One a Demon who always lies, and the last one is Human who can lie or be honest accoding to their whim.
The first staircase.
Person A: "I am an angel"
Person B: " I am not human"
Person C: " I am a demon"
Can you deduce who is whom ? whom is who ?
[Getting the 'Gist' of it ? they're quite simple when you think about them; but how often in a day do we really think ? These really help me wear my brain out before bedtime and the subsequent sleep is great - better than anything medication can provide]
