(I'm new to the forums)
When I came, I expected to see chess puzzles...
But anywho...ahh, riddles - I am the master of riddles.
The following (although not quoted word for word) is from possibly the most famous logical thinker of recent times, Raymond Smullyan. I believe I read it in his book, "Alice in Puzzleland" (although it might have been "What is the Name of this Book?"
. It resembles the others, but it's much harder (and if you've heard it before, please don't say the answer). Oh, and PLEASE read over the riddle before you answer; you wouldn't believe how many times I've posted this in a forum, only to have someone who thought they've heard it before answer it with a completely unfitting (and ignorant) response:
You are at a fork in the path in the jungle. For some reason or another you cannot venture from the path, nor can you turn around and go back from whence you came. One path holds certain doom, the other certain safety, although you don't know which is which. Both paths harbor a tribe (that is, somewhere in the distance, along each path, are tribes of natives). Either tribe could be truth tellers or liars (which means BOTH tribes could be liars or BOTH truth tellers, or one of each). Standing at the fork are two natives. You don't know whether each is a truth-teller or a liar, nor do you know what tribe they came from (that is, both could be from the same tribe, or they could come from seperate tribes; both could be truth-tellers, both liars, or again, one of each).
You get to ask both natives one question each. You must be absolutely certain that, with the given information and the questions you ask, you'll be taking the path of safety. What do you ask?
