    Is 'no' the answer to this question? :biggrin:

    Assuming the normal meanings and that you meant truthfully answer with a 'yes' or 'no'.

    .......yes,

    I don't think there is one.

    It is like saying: Can you show me a dog that is not a dog.

    Then 'no' is not the answer to the question.

    I think that

    Is 'no' the answer to this question?

    is what Mk is after. Try to answer it with a 'yes' or 'no'.

    :confused:
    MK is confused because he is wondering if there is one, and I say Yes, which means there is one.
    But what question needs to be answered ?

    :rofl: Who is on first!

    Sorry. Let Q denote the question
    Is 'no' the answer to this question?
    I think Q is the question Mk was looking for.

    Absolutely, yes, the answer to that question.

    You should have misunderstood that short post, I believe.

    Are you studying up on how to drive yourself crazy? PF has a nice Philosophy section for that.

    Well, because of the confusion, I wasn't going to mention this, but it would be nice to know how Mk defines a 'yes or no question'.
    If Mk's definition is
    x is a yes or no question iff x can be answered with either a yes or a no but not both​
    which seems reasonable, then the answer to the original question is of course 'no'. (If x cannot be answered with either a yes or a no but not both, then x is not a yes or no question.)

    Yes, I thought for a few minutes about the answer of this question and it was really confusing. Anyway I think this question has an answer anyway. I like trick y questions alot but I don't think this 1 would be 1 of them! :wink:
