Can this question be asked?
Knowledge has limits.

"Mind is not Buddha. Knowledge is not the Way." But then, even saying this is leading you astray again, so I should shut up. Your question can be asked, because you have asked it. But not all questions make any sense. I think that the error is the choice of your second word, "Suppose you..." This word has no referent. But to communicate with you, I need to resort to meaningless terms like 'you' and 'I'. Try not to get hung up on them.

"Have you had breakfast?"
