But then nothing about Ross' "EF" makes any sort of mathematical sense.> > The reals:  well-ordered.Not by Ross. While by some considered theoretically possible, no one has yet come up with any explicit well-ordering of the reals, and for Ross to suggest that he has done it is the arrogance of abject ignorance.>--
