Species definitions!

Oh, I'm not saying the field work is not necessary. Quite the contrary! But
if we observe the countless Fritillaries with the intent of merely drawing
up a tally of "245 X, 126 Y, 57 Z... etc." without progressing beyond this
level of study, then what is the worth of the field work, either to
ourselves or to science? The poor fellow who has taken the time and spent
the energy to determine that there were "223" instead of "225" Juvenal's
Duskywings (and I'm using an example of a posting I saw from this past May-
and the poor fellow reported them as "Juvenile's") himself is probably
unaware of the treasures that exist on the other side of the door of
understanding. That's what I'm talking about. This is why someone taking the
time to count the actual number of Cabbages seems worthless to me while the
person may be at same time being blind to the observation of the degree of
white banding on an astyannax or the degree of hybridization between
weidemeyerii and rubrofasciata etc. etc. Or even to the understanding of why
some astyannax have bands and others don't. And the worst factor is that
some people in leadership capacities permit or even propagate ignorance in
others.
