"Hennig (1950) initially got Woodger's (1952) analysis of the hierarchical
organization of organisms, or taxa, from Bertalanffy (1932) (...); he became
acquainted with Woodger's (1952) and Gregg's (1954) original work only at a
later date (Hennig, 1957, 1966)."
It seems that this bit of history might be relevant to J. Metlevski's recent
comment about the connection between Bertalanffy and systematics.
On a separate issue, thanks to P. Lehtinen for pointing out to more
philosophy of science literature relevant to the subject matter of our
careers. It is nice to consider that after all, the amount of systematists
who are critical and open-minded might end up being much larger than those
who think that the meaning of meaningful things could only be found in the
