Claiming « sqrt(-1) is not in the territory » is an axiom. It's a
definition. You are defining sqrt(-1) as meaning something that is not in
the territory. The question is whether that's more useful than claiming
that sqrt(-1) is a pattern that appears in the territory.
Same goes for any other number, actually. sqrt(-1) is not in a special
There are other ways to explain anything that uses complex numbers. In
math that's called an Isomorphism, and there's a lot of abstract algebra
that is about those equivalences. Especially the Representation Theory. It
doesn't make sqrt(-1) any more virtual than any other numbers. If you go
through enough algebra, you will see every number and every numeric
operation has plenty of equivalences of any kind... that doesn't make them
more virtual, that makes them more existent.

Bryan took it to pd-ot where no-one ever writes. I had to subscribe to it
in order to be able to reply. pd-list's volume is very much under its
average, too. Bored people can hit the Delete key quite easily.
