I don't quite follow. I agree that none of the
proposed solutions of the VMs has any explanation
for the labels, with the exception of Brumbaugh,
who does the opposite and only 'explains' some of
the labels, and not very convincingly IMO.
Any reasonable theory should be able to give
a reasonable explanation for the labels. There
are, after all, a lot of them, and they appear
in essentially all sections of the VMs.
