It is sad to witness the confusion that creationism inflicts
on its advocates. Truly blatant mistakes result when creationists
try to support their scientifically untenable religious beliefs.
Some examples from the Fall-Winter '86 issue of Origins Research
may help to illustrate this point.
Mistakes Regarding Thermodyynamics
Walters: "...Thermal energy cannot be converted
into mechanical energy unless a capable engineer designs a system
that includes a boiler, turbine,...etc,..."
Fact: Massive amounts of thermal energy are routinely
converted into mechanical energy everyday. Moreover, this has
been going on for eons. The convection currents at sea as well
as the entire hydrological cycle represent mechanical energy from
the sun. The processes involved are not only understandable, but
completely natural and do not violate the second law. No boilers,
turbines, etc. and no intelligent engineers are involved.
Walters: "...of course, one could also define the
second law as: ...mass never diffuses against a concentration
gradient..."
Fact: Mass in atomic form is known to spontaneously
diffuse against its own concentration gradients in a wide variety
of solid state processes and in liquids as well. Indeed this is
a fundamental aspect of every alloy system which exhibits the
so called "spinodal decomposition" mechanism of phase
transformation and there is a fairly extensive literature on the
subject. Most of the work in the last 20 to 30 years was pioneered
by John Cahn (then at MIT, now at the National Bureau of Standards)
but the idea originated with J. Willard Gibbs back in the late
1800's. One need only account for bonding energies in the proper
way to see how this apparently "uphill diffusion" process
can proceed quite spontaneously and in complete accordance with
the second law of thermodynamics.
Walters: "If (JWP) asserts ...that evolution has
no problems with thermodynamics, my understanding of thermodynamics
forces me to conclude that (he) hasn't looked very far".
Fact: So nonexistant are evolution's problems with thermodynamics,
that expert thermodynamicists refer to such creationists' claims
as "red herring" issues. When Professor David B. Wilson,
editor of Did the Devil Make Darwin Do It?, asked me about
contributing a chapter on thermodynamics, he found I had just
completed one for Laurie Godfrey'sScientists Confront Creationism
(which Tracy Walters reviewed). So he decided to get the views
of a physical chemist, Prof. H. F. Franzen, rather than have a
rehash of mine. Significantly, Franzen titled it "Thermodynamics:
The Red Herring" as if to underscore the way that creationists,
in his view, have tried to concoct non-existant contradictions
with thermodynamics. I strongly recommend Prof. Franzen's paper
to Tracy Walters and to all of his creationist colleagues.
Walters: "...Information in a closed (informational)
system always decreases."
Fact: Let ten or so microbes be introduced into a closed
but warm aquarium that houses a small population of plant life
and other nutrients. Eventually the microbes will multiply to
perhaps millions before achieving a dynamic equilibrium with the
plant population, which might also have expanded in the process
(more microbal waste products for them to feed off). If the information
in a single cell is anything like the creationist biochemists
claim, the information content of such a closed system will have
increased astronomically, and with no outside influences other
than the heat sources (like the sun) and/or heat sinks in the
surroundings. As with the earth's biosphere, no supernatural intervention
of any sort is required to explain this dramatic increase in information.
Indeed to entertain such an explanation serves only to confuse
our understanding rather than clarify it.
Walters: "While it is generally believed that we
accept the laws of thermodynamics because of overwhelming empirical
evidence, it has been shown that the laws of classical and statistical
thermodynamics can be derived from ...work in information theory.
...it is interesting to realize that the laws ...can be defined
in any number of ways, each of which can be shown to be equivalent
to the others" (But recall Walters' mistake above equating
the second law to the impossibility of diffusion against a composition
gradient! JWP)
Fact: The laws of classical thermodynamics are far more
general than those of stastistical thermodynamics and therefore
cannot be equivalent. The reason is that classical thermo is not
committed to any assumptions about the fine structure of its systems,
whereas statistical thermo is committed to such assumptions. This
generality, which is unique to classical thermodynamics, is what
enabled Einstein and Planck to apply classical thermo with complete
confidence when embarking on their respective journeys into the
uncharted waters of relativity and quantum theory (see chapter
four in Segre, 1980). Unlike the laws of classical thermodynamics,
the laws governing particle collisions and momentum transfer --
both of which are fundamental to statistical thermodynamics --
do not remain unaltered in the same way. Like the laws of electromagnetism
and Newtonian mechanics, they must be corrected for relativistic
and quantum effects. Nor can classical and informational thermodynamics
be equivalent -- contrary to Walters' suggestion -- because information
theory contains still other hypotheses to which classical thermo
is not at all committed. The fact is, statistical and informational
thermodynamics are actual hybrid theories which are more specialized
of limited than classical thermodynamics, precisely because of
the other postulates that get added.
To summarize, neither evolution or any other life process constitutes
a clear-cut violation of any laws of thermodynamics. By claiming
the opposite, the creationists only succeed in documenting their
confusion -- not only in regards to entropy but also as regards
the second law of thermodynamics itself. If they really wish to
shift the debate to information theory or to statistical thermodynamics,
or even to irreversible thermodynamics (as developed by Onsager,
Prigogine, etc.) then they should state explicitly what it is
about these theories that is violated and then develop their case
accordingly.
Perhaps Professor J. A. Cramer -- himself a devout creationist
who thoroughly rejects evolution -- has said it best (Cramer,
1978):
...I no more concur with the general theory of evolution than
any of the proponents of this view (that evolution violates the
second law), but it is a mistake to defend oneself with faulty
arguments.
Mistaken Protocols and the Philosophy of Science
According to well established protocols, as discussed in the
philosophy of science, there is little or no basis for considering
what we may or may not attribute to some hypothetical thing until
there is some solid evidence that the thing in question really
exists. This applies to all hypothetical notions and not just
to those we imagine to be of a naturalistic sort. It would be
rather silly, after all, to reopen the issue of perpetual motion
(or the "luminiferous Aether", or phlogiston, or whatever)
simply because certain advocates -- religious or otherwise --
insisted that these were really supernatural notions all along.
Nor is it not just the scientist or atheist who should find this
to be silly. Any layman or even any theologian being implored
to invest time, money, or effort in any such project would also
be well-advised to demand existence before investing.
Most of the hypothetical notions conceived by humans (whether
these notions be scientific, nonscientific, natural, supernatural
or whatever) turn out to be so seriously mistaken in some sense
that we can pass them off as mere figments of the imagination.
Newton's "luminiferous aether", Stahl's "phlogiston",
and the idea of work or heat from nothing (i.e., perpetual motion)
were once thought by many people -- scientists and nonscientists
alike -- to have a real existence. But to the astonishment of
almost everyone at the time, all have since been shown to be mere
delusions. Creationism is but another of the once popular delusions
that also had widespread acceptance in scientific circles.
The realities of certain other notions from science have
been established, but as regards the supernatural, nothing has
as yet been shown to exist (outside the imaginary realm of pure
delusion). In any case, science has learned from these past experiences
to place the highest priority on establishing at least some compelling
evidence for existence, before considering an idea to be a possible
explanation or cause of observed occurrences.
To summarize, the philosophical situation is this: With no
compelling evidence to date for the existence of anything supernatural
-- much less a supernatural Creator with intelligence (!) -- science
simply rejects creationism. This will not change until the creationists
provide some form of compelling scientific evidence for the real
existence of their hypothetical Creator. Not only scientists but
others, too, are justified in this, because creation theory without
a creator would be just as silly as gravitation theory without
gravity or quantum theory without quanta and so on. It matters
not how fervently the advocates plead for their Creator hypothesis;
until they provide solid evidence for His (Its?) existence, the
null hypothesis (no creator and no creationism) will continue
to prevail. This is the same as saying the alternative hypothesis
(creationism) will continue to be rejected.

Acknowlegements
I wish to acknowledge with thanks those who
sent me copies of the letters they wrote to the editors of Origins
Research. Some of the responses given above were based on
those letters, particularly the ones from J. Richard Wakefield
of Beaverton, Ontario and Prof. Robert E. Carver of the University
of Georgia, Athens. Though I did not use it here, the letter by
Frank Arduini was particularly insightful and the most relevant
of all to the subject of thermodynamics.
