It's the idea well it goes something like this we didn't resolve, once and for all, either the cases or the principles we were arguing when we began and if Aristotle and Locke and Kant and Mill haven't solved these questions after all of these years who are we to think that we here in Sanders Theatre over the course a semester can resolve them and so maybe it's just a matter of each person having his or her own principles and there's nothing more to be said about it no way of reasoning that's the evasion.
