        Subject: the sum of the parts

Robert Jervis, in System Effects: Complexity in Political and Social 
Life (Princeton, 1997) and Frank Golley, in The History of the Ecosystem 
Concept: More than the Sum of the Parts (Yale, 1993), argue, as Jervis 
writes, that "If we are dealing with a system, the whole is different 
from, not greater than, the sum of the parts." He cities work across 
several disciplines, pointing to biology as the starting point of many 
scholars who have reached this conclusion. What about the disciplines of 

Our machine, comprised of numerous 'black boxes' whose inner dynamic 
workings are in principle unknowable, would seem to me an example worth 
our consideration. It was explicitly designed as such an 'ecosystem', 
though in the language of human neurophysiology (von Neumann 1945). Its 
user-interface is obviously not more than but different from all the 
operations which sum to it. (Indeed, from an engineering perspective, 
those operations are clearly more than what they sum to.) Golley writes 
that "There was an exact moment of birth" for the concept of an 
ecosystem, "when the English ecologist Arthur Tansley created the word 
and presented it in a technical paper" in 1935. Here's the passage:

(Tansley, "The Use and Abuse of Vegetational Concepts and Terms", 
Ecology 16.3, p. 299)

There is the historical question when we extend Robin Gandy's 
"confluence of ideas in 1936", i.e. "the almost simultaneous appearance 
in 1936 of several independent characterizations of the notion of 
effective calculability" (in The Universal Turing Machine, ed. Herken), 
among which was Turing's, to the systems-thinking of the above. But 
there's also the question of computer systems as ecologies 
that include and perhaps now come close to defining us.
