[Taxacom] Reality scence

I agree with Jim Croft's take on this. There is a corner of philosophy
dedicated to a pragmatic view of what's-out-there, called variously
antirealism or verificationalism, or some such pejorative term.
I think that we clearly have a spectrum of what to place our bets on
when making decisions about how to deal with the outside world. Stuff we
have right next to us are pretty certain units on which to project the
future, and different distances and degrees of factualness (a fact is a
well-documented observation) provide different degrees of making a
correct decision. A species definition is useless by definition if it is
useless.
Arguing about reality has a long and distinguished history, but advances
are made in science independently of such arguments, or even at times of
scientific method.
