exnihilo,

Your "intolerence of infinities" point has psychological as well as mathematical aspects. We seem to have a wired-in disposition towards "closure" which manifests perceptually (night sky seen as flattened dome) and cognitively as a search for "ultimate causes" (monotheism and the concept of "a creator").
It seems to me that infinite regresses are unavoidable for we are imevitably bound by Godel's incompleteness theorem implying at least one assumed axiom.
