| Jun 18 at 16:01 | comment | added | Josh | @GentlePurpleRain "among your companions". A clearer way of wording that question could be: "If either of the other two guards is telling the truth, point to him (otherwise don't point to anything)". If the guard you asked is truthful, he won't point to anything (other 2 are liars). If the guard you asked is lying, he'll point to the other liar (1 is truthful and the other is the other liar). | |
| Jun 18 at 15:33 | comment | added | GentlePurpleRain | You might be able to say something like, "If any guard other than yourself is a truth teller, which guard is it?", but I still think that if it's valid for the truthteller to give a non-answer, it should be valid for the liars as well. They should be able to imitate any answer that the truthteller gives. | |
| Jun 18 at 15:30 | comment | added | GentlePurpleRain | Why couldn't they all just point to themselves? Also, this isn't actually a question; it's a directive. That makes it impossible for them to lie or tell the truth, because they aren't answering anything; they're simply being given a directive. There is nothing to indicate whether knights/knaves follow directives or not. | |
