Alternatively one could try to address Woodger's paradox, but that would  
entail viewing organisms generatively and not historically; hence I will  not 
hold my breathe.

I'm glad  you asked, Phil. What it comes down to is should a
classification be  informed by descent with modification, namely one
taxon generating another  taxon, i.e. macroevolution, OR not? 

The Linnaean system of nested  categories does not represent well either
inferred present-day clades or  inferred sequences of taxic changes
through time, so there is no Right  Classification to shoot for, just an
approximation of a cladistic tree or a  Besseyan cactus using nested
relationships. Of course one might invent a  Macroevocode to compete with
the Phylocode. Hmmmmm . . .

Hi,Tom, Phil here,

I know that Our  Herb has switched to the APGIII order of things, right
or worng. We had the  confinence that APG's order might be close, if not
exactly, the  arrangement. We thught it close enough that we believed no
huge exceptions  occur in the future . No huge shuffles, in
practilicality. We may be wrong  or OK, to some degree that we kind of
believe that the molecular botanists  are on some kind of lasting trail.
But who knows?
