Very Half-Totally Wrong, imho.

[Richard Fiero]

I don't believe that it's reasonable to expect a 20th century 
discussion by the author in a text with a 19th century timeframe. Far 
from being limited to a Gibbs-Clausis-Boltzman understanding of 
entropy, P is rather up to date:
Col49
Pg 48. "She did gather that there were two distinct kinds of this 
entropy. One having to do with heat-engines, the other to do with 
communication. The equation for one, back in the '3o's, had looked 
very like the equation for the other. It was a coincidence. The two 
fields were entirely unconnected, except at one point: Maxwell's Demon."
Pg 49 "Entropy is a figure of speech, then," sighed Nefastis, "a 
metaphor. It connects the world of thermo-dynamics to the world of 
information flow. The Machine uses both. The Demon makes the metaphor 
not only verbally graceful, but also objectively true." "But what," 
she felt like some kind of a heretic, "if the Demon exists only 
because the two equations look alike? Because of the metaphor?" 
Nefastis smiled; impenetrable, calm, a believer. "He existed for 
Clerk Maxwell long before the days of the metaphor."
Pg 50 "For John Nefastis (to take a recent example) two kinds of 
entropy, thermodynamic and informational, happened, say by 
coincidence, to look alike, when you wrote them down as equations. 
Yet he had made his mere coincidence respectable, with the help of 
Maxwell's Demon."
GR
Pg 435 Liebig himself seems to have occupied the role of a gate, or 
sorting-demon such as his younger contemporary Clerk Maxwell once 
proposed, helping to concentrate energy into one favored room of the 
Creation at the expense of everything else (later witnesses have 
suggested that Clerk Maxwell intended his Demon not so much as a 
convenience in discussing a thermodynamic idea as a parable about the 
actual existence of personnel like Liebig . . . we may gain an 
indication of how far the repression had grown by that time, in the 
degree to which Clerk Maxwell felt obliged to code his warnings . . . 
indeed some theorists, usually the ones who find sinister meaning 
behind even Mrs. Clerk Maxwell's notorious "It is time to go home, 
James, you are beginning to enjoy yourself," . . .

Moreover I think that the demon well stands for the militarization 
and corporatization of our culture in applying the laws of 
thermodynamics to economics and social sciences.
