David Burkhead and David Froelich made the same point.
Parsimony isn't everything. There's respect for data, elegance,
other factors that should be taken into account, and probably other
things too. But for what it is in this case, it's on my side.
I quote two phenomena (y) and (z) that need explaining. I give
one explanation. You give two. So I've got parsimony. Big deal.
Your correct response is to say I'm omitting phenomena (a) to (x)
or that my (z) is not a significant problem, or that my (y) does
not work, or whatever.
But on *parsimony*, I win (a very small victory).
