True. It can be very frustrating for people when their "fuzzy-logic" (for lack of a better word coming to mind) is not accepted as a proof and they don't see how it isn't iron-clad. Fuzzy-logic gets us through most of everyday life with minimal mental burden, and so is definitely useful, but it doesn't hold up in an argument where you're trying to prove something. It can also go the other way though; some topics are inherently fuzzy, and trying to impose rigour on them just ends up wasting everyone's time and leaves nobody convinced.
