The paradigm shift was Darwin, and the idea that higher-level 
classification reflects something in nature rather than an artificial 
"system of convenience". Hennig simply affirmed that the "something" was 
monophyletic groups.

Fred Schueler reminds us that “It’s ironic that the anarchy of ‘descent 
with modification by natural selection’ should give rise to the only 
really important or useful natural hierarchical arrangement we know of.” 
Linnaeus was attempting to distinguish the individual species created by 
God, and yet his system has worked for 250 years.

It's important only to a historian of science which of the four elements 
were involved in the metal mercury. But biologists even centuries ago 
recognized units of the natural world that we still find useful. It's 
true that I can't pick up a work from 1870 and be secure in recognizing 
the names of species, but there are nomenclators to help me with that. I 
can definitely be confident in recognizing names in a work from 1970.

If we make a major change in nomenclature, we will need nomenclators for 
everything (most people on this list agree that is a noble goal, even if 
a few think it is impractical), and we'll need a list of names in 
current use (the bacteriologists have been there for a while, and the 
other codes are coming around). These are *prerequisites* for a 
fundamental change in nomenclature, lest it throw us into the dark ages 
of redescribing everything. The bacteriologists were successful in 
making such a change (although many would argue it doesn't go far 
enough), but there's a lot of work left to be done for everyone else.
