@jgweed,
But we are trying to arrive at a source of knowledge that is "perfect" in every single way, and it appears like even mathematics(the "God" of all knowledge) can be called on to doubt!
What good is having a degree of certainty, when you can have the actual phenomena it self.. or in other words, why prefer the analogy(degree of certainty) when you can have the phenomena(absolute knowledge) it self!
Well, this turned out more of a epistemological question!
