David,

This might possibly be a meaningful remark clarifying a lot in the
confusion that apparently reigns - but  only if you could indicate which
method is so utterly intractable to formalization that it could not
possibly be carried out by a numerical algorithm - and thus might qualify
as a Real Cladistic Method.

Otherwise - Don Colless may have a serious case of Deja Vu on reading this
discussion. See Syst. Zool. 16 (1967): 289-295; 18 (1969) 115-126.
