I'm sure people with a mathematical bent have noticed the implications
of things like Tarksi's "sphere doubling" or "inside connected to outside"
theorems or even Arrow's Theorem nad various voting dilemmas.
I think you posted (and I read somewhere) something r.e. problems
with theories which allow infinities. All those Infinity Hotel paradoxes
and suchlike.
You don't want to look too close to the underpinnings of things
that appear to be working OK. :)

BHP Billiton chief Andrew Mackenzie has told reporters his accountants
tell him the deficit levy he'll pay under the Hockey budget will hurt
him just as much as a pensioner paying for a couple visits per week to
the doctor. Mr Mackenzie earns a base salary of $2 mn pa; the 2% levy
will cost him $36.4k. An Austroyan pensioner receives about $20k pa;
and 3 doctor visits per wk will cost $21 under the new rules --
about 5.5% of their income.
