Is "no" the answer to this question?


              In other words:

Is “no, it is not” a correct answer to this question?

              Well, “it is not” means
              that “no” is not a correct answer,
              so if “it is not” is correct,
              then “no” is not a correct answer.

        So, if it is the case that “no, it is not” is a correct answer,
              then “no, it is not” is not correct:

                        It would be correct and not correct.

              But if it is not correct,
              then it is not the case that it is correct,
              so it cannot be correct as well as not correct.

        Does it follow that it is not the case that it is correct?

              But if it is not correct
              then “it is not” is correct, so
              it would be correct as well
              (and it cannot be both).

        Could it be that there is no correct answer?

              But then “it is not” in particular
              would not be a correct answer, and
              it would also, as above, be correct
              (and it cannot be both).

        Could it be that logic is not what we think it is?

Do we exist in a purely physical world?
        Would highly evolved apes have evolved
        to be perfectly logical in such a world?
              You might wonder if appeals to logic
              should be taken more seriously than
              political rhetoric.

              As Dr. Who said:
        Logic, my dear Zoe,
merely enables one to be wrong with authority.

Are we left with everything being political?
No, because answers to questions can be
as correct as not. Consider this question:

              Is “it is an apple”
              a correct answer
              to the question
              “What is @?”?
        Suppose that @ was originally an apple,
        and that it is having its molecules replaced
        one by one with molecules of beetroot.

        “It is an apple” was originally a correct answer,
        but it will eventually stop being correct.
        If that answer must be either correct or else not,
        then an apple can be turned into something else
        (such as a mixture of apple and beetroot)
        by replacing just one of its molecules.
        Because that is absurd, it is plausible
        that @ can be as much an apple as not,
        that “@ is an apple” can be as true as not,
        and “it is an apple” as correct as not.

If “no, it is not” is as correct as not,
then the fact that “it is not” means that “no” is not correct
just means that “no, it is not” is as incorrect as not, and that is the same
as it being as correct as not. There is no contradiction, only consistency.
        So, the fact that all of the other conceivable answers
        (except the one that says not to bother being logical)
        are clearly contradictory means that

              “No, it is not” is as correct as not

        (if logical reasoning is better than political rhetoric).
