is ‘four’ a correct answer?
No, there aren't any correct answers* because it's not a correct question. It's like asking someone to add up 1+ 4 + fish + blue. That's why there is argument over it - different people are coming up with different reasoning to try and make it make sense.
* unless you argue 23, which is pretty peurile along the lines of 'how do you spell 'it' joke we all loved aged 9 or so.
Makes perfect sense to me, sure it's contrived but you can deduce the answer with logic. You can't deduce an answer to 1 + 4 + fish + blue, it's not a comparable question.
*You* think you can deduce the answer with logic.. but it's logic you've chosen, which backs up my claim.
OK, you're right, it's 42 - happy now?
All logic is based on your initial axioms if choice. That's the entire basis of logic
