But that doesn't make any sense. I could just stack bags of dirt in the order of 1, 8, 27, 64, ... and call it 3rd powering, but where would the intuition be in that? That is a requirement for teaching, is it not? First we had a poster that identifies intuition with reason and now we have one that identifies it with rhetoric.
