(September 1974): 99-101.
Professor Isis and Doctor Notnot were distinguished faculty members
at the Passion
for Truth Institute for advanced studies in Philosophico paleontology (PP.). It
was my undeserved privilege to accompany these great men each Sunday afternoon
as they walked and talked in the gardens at Blunder near the institute. My task
was to keep score in the unusual but fascinating game which they
played. Of course I had to take notes in shorthand so as to be able to reproduce verbatim their
dialogue in order that each could check the other's points at the end
of the game.
One particular Sunday afternoon stanch out vividly in my mind, and is
worth preserving
for the scientific community. And so for the advancement of PP. to which these
men unstintingly gave their best, i have consented, with permission
from the P.T.i.
archives, to release for the first time this most memorable dialogue.
On this particular day Professor Isis was unusually anxious to begin
discussion.
No sooner had the three of us walked through the garden gate than he blurted at
Doctor Notnot.
Isis: Do you know that there are still living some diehard anti-evolutionists?
I have never in my life been so humiliated by a colleague as I was at
the conference
in Tranquil last week. I used the word "evolution" several times in
the paper which I delivered and this man actually questioned not only my use of
the word but the very truth of the concepts entailed. I thought at first that
he was joking but I soon learned he was in dead earnest-ever so serious.
Notnot: How did you answer him?
Isis: Considering that I was allowed only one and one-half hours
(including discussion)
I couldn't take much time. I expressed my dismay that any scientist
in this enlightened
age-it's been over a century since evolution was clearly established-could be
so ignorant of the facts. Can you imagine it, in the midst of the
world's greatest
scientific minds, a man would dare question these laws of nature?
Notnot: It's a pleasant day, Professor, and I do not intend to wrangle, but is
it not conceivable that most of these men of science are mistaken.
You are surely
not proffering the argument that because most of the great scientific
minds believe
evolution to be well established, then it actually is. That would be the democratic fallacy.
Isis: Good heavens, you're beginning to sound like him! Of course I'm
not suggesting
that because most think it is so then it is so. It is not the most at all that
I'm emphasizing. It is the fact that the most-I would say almost
all-are topnotch
men in science. I am not emphasizing the quantity of those minds but
the quality.
However, if you do have a great number of such great minds agreeing, then the
likelihood of evolution being well grounded is increased. And such a consensus
is a bit more indicative of the truth than waving your right hand or
saying Aye,
wouldn't you agree, Doctor?
Notnot: Yes, but great minds, whether numerous or few, do not ipso
facto guarantee
the truth of the ideas to which they unanimously subscribe. It may be
that these
minds, great though they be, have never applied their thinking to the
basic assumptions
of biological evolution. Perhaps with little more than a student's intoductory
course on the subject they have assumed that all is well at that
level; in which
case drawing upon their credentials would be committing the fallacy
called Appeal
to Authority. Besides, you know yourself that the trail blazers in science have
been precisely those people who have not had the majority of great minds with
them at the inception of their discoveries. What greater example
could we adduce
than Einstein?
Isis: Granted there is no absoluteness to this kind of inductive inference, but
there is a much greater probability that the most in this case are
right and this
fellow-I wish I could remember his name-is wrong. The burden is his
to establish
the case against evolution.
Notnot: Well, did you give him a chance?
Iris: As I said there wasn't much time for discussion. Besides I can't imagine
what he could have said.
Notnot: He might have questioned you on the argument from paleontology.
Isis; What do you mean?
Notnot: Is there really any solid evidence for the claim that one
species evolved
into another? Are there not great gaps in the fossil record where you
would expect
to find important intermediate forms in the chain of ascending complexity?
Isis: My dear doctor I can assure you that the evidence is very solid! Are you
not aware of the literature on the subject? I can produce a dozen books from my
library alone illustrating the gradual change in morphology of organisms which
have been taken from strata that are reliably dated. Now we need not labor the
elementary, that younger deposits lie above the older ones. From the
concomitance
of old strata and simple forms, as well as young deposits and complex
forms, may
we not safely assume-indeed are we not forced to the conclusion-that the lower
forms are the ancestors of the higher forms; especially when we have
in some cases
such a complete "genealogy?"
I was never sure whether Doctor Notnot had started out playing the
devil's advocate
and later discovered the difficulty of his position which he then felt obliged
to defend, or whether he was serious from the beginning. In any case his next
query was offered in an apologizing tone quite atypical of the doctor.
Notnot: But do these evidences of graduation really exhibit a change from one
species to another? What I mean to ask is: could we not think of these fossils
as variations of A or C rather than as evidences of transitional form B, where
B is the link between the radically different forms A and C? Do we really have
all the stages between any species A and any other species C?
Isis: Forgive the pun Doctor but that is a specious argument. Granted we do not
have the table completely filled, but we have enough gradations of complexity
to establish the principle of evolution from lower to higher forms.
Your criticism
reminds me of Zeno's paradox. No matter how many gradations you were presented
with you would always say there wasn't enough evidence to establish the case.
If I showed A1 and A2 you would want to see A1, Alb . . . . A2. And if I showed
you Ala and Nb you'd want to see Alai, A5° , . . . In principle you would
never he satisfied.
Notnot: Sir, I think that I have already conceded that there are changes within
limits. This is a fact observable today. I have no quarrel with the microcosmic
aspects of change. It's the so-called macrocosmic changes
that I'm concerned about. I do not argue with At, A2,
or Ct, C2 . . . C'. What I wonder about is the form B which evidences
the transition
from A to C; that form which clearly has A and C characteristics, Surely we can
expect such evidence from evolutionary doctrine.
Isis: But you are arbitrarily setting what you call the boundaries
and then saying
that there are no fossils which exhibit a boundary line form. By
contrast I have
first presented evidence, not imaginary boundaries, and from this evidence of
gradual and extended change have established the spectrum from A-form
to C-form.
But you are saying that B is non-existent, What B are you talking about?
Notnot: Well for example, is it not supposed that reptiles evolved into birds?
Where are the fossils that have both birdlike and reptile-like characteristics?
The strata should be replete with these forms if in fact such forms
ever existed.
Isis: There is one very good example of which I'm sure you're aware,
the Archeopteryx.
But I realize there is some doubt connected with that transitional form and I
expect that you won't accept it as evidence. Just for argument's sake I shall
give up that form and suppose that the B form in this case does not
exist. There
are still two mistakes in your argument. One is a fallacy and the other is an
oversight regarding the nature of scientific investigation.
The fallacy is Argutnentum ad igncsraniam. You are arguing from the fact that
we haven't discovered any evidence of B-form to the conclusion that B-form has
never existed. There may be several reasons for the B-form not being preserved
which we shall discover with further geological investigation. Or
perhaps through
further investigation the B-form will yet turn up. By contrast, however, notice
that I have not argued from the failure of proof on one side to the
establishment
of proof on the other. I have adduced the gradual sequence of forms and argued
from that evidence. And here I'm speaking about forms that would be universally
accepted by the scientific community-not like the Archeopteryx. And this brings
me to your second mistake.
In science we move from the known to the unknown, not vice versa.
Anomalous situations
do not disprove the rule, much less establish a contradictory rule.
The probability
of a theory being a fact increases as the evidence continues to
support that theory.
And I'm quite safe in saying that the paleontological evidence has increased to
the point where we can call evolution a fact.
Notnot: I quite agree, Professor, that a scientist ought to move from the known
to the unknownnot withstanding the fact that hypothetical speculation plays an
important part in the scientific thought process-as regards what can be stated
as fact. But I fear that you accept too easily what you later claim
to know. What
you would call a fact I would call an interpretation of the facts and, I might
add, not an interpretation that I care to endorse. Too much weight is
being placed
on the phenomenon of one fossil appearing after another fossil. It
comes precious
close to the post hoc fallacy which is committed when you argue that
because C comes after A, then A is the cause of C.
Isis: I beg to differ my dear doctor! I do not see how I'm committing
that fallacy
at all.
Notnot: Let me illustrate...
Isis: Please do!
Notnot: Suppose that you and I walked into a museum which displayed the history
of bicycles. Imagine that the stages are represented along one long wall. Your
eye moves from left to right viewing first the unicycle, second the primitive
bicycle, thirdly the tricycle and finally a motorcycle. Now tell me, would you
think that 2 evolved from 1, 3 from 2 and so on?
Isis: Of course not.
Notnot: Then why argue that because one form appears after another
that the latter
form is the result of the former one? Evolution, if there is such a thing, is
not in the object observed but in the minds of the inventors.
Isis: Sir, your line of argument is irrelevant. You are
arguing from analogy. (Professor Isis was becoming
visibly disgruntled with Dr. Notnot.) Anyone who knows the first
thing about logic
knows that analogies do not prove anything, they only illustrate. You
are taking
one general characteristic in one case, namely the gradational
complexity of the
bicycle, and comparing it to a similar characteristic in the other, namely the
gradational complexity of fossils, and arguing that the same
developmental conditions
prevailed in both cases. Surely you see the flaw!
Notnot: No, professor I do not see the flaw, and unless you can
produce more evidence
than fossil gradations, you have no right to speak of any
interconnecting causes
of development. In the case of the bicycle we not only can talk to people who
lived through its "evolution"-first hand accounts-but we have plenty
of documentation besides. We know that men made them and we can
observe and repeat
the process by which they were made.
Both men by this time were extremely intense and I was writing like wildfire to
get down every word.
Isis: Obviously, doctor you are glossing over the evidence for development that has already been given you. For some
reason you close
your mind to the fossil record. If I say more I will be simply
laboring the obvious.
The mechanisms of development are also observable today. In your own lifetime
you can observe the change in the average height of people in a
country. You must
also be aware of the mutant forms that have been artificially
produced among plants,
animals and insects. And it is right there that your bicycle analogy
has a gaping
hole. Even primordial organic material in the biosphere is not as
rigidly formed
and lifeless as bicycles. These forms are changeable and adaptable and not cast
iron.
Notnot: But sir, you both smuggle in a false assumption and commit a fallacy.
There are two reasons for not being able to use the fact of mutations
as evidence
for a mechanism of evolution. One, most mutations are deleterious to!
the organism
and two, those which are not deleterious cause nothing more than a
change in part
of the organism. That is, eyes may change from one color to another
but they remain
eyes. Tails may become shorter or longer but they remain tails. And this brings
me to the fallacy of which you are obviously unaware: the fallacy of
composition.
You are arguing from the properties of the parts of a whole to the properties
of the whole itself. It's like saying that because each part of an
engine is light
then the whole engine must be light. In your theory of evolution you
are forgetting
the organizational and compositional factors. To say that parts of an organism
mutate is not to say that the whole organism does. Forgive the pun but that is
the gaping whole.
I'd never seen Professor Isis so flustered.
"Why, ever since I've known you you have never brought up these questions.
You . . . you . . . rat!"
"Ad hominem," retorted Notnot.
"No, I take that back, you're not a rot, you're a monkey's
uncle."
Quite pompously Notnot said, "I've got you, because the lower primates are
older than the higher primates; and if I'm a monkey's uncle then your
tables are
turned upside down and your theory of uniformitarionisms is
defeated."
With a smirk Isis came back with, "False presumption, my dear doctor, for
you are a living fossil!"
With that remark Professor Notnot turned 180' and stormed down the path by the
pond. Professor Isis was also in no mood far tea. He too charged off.
I was left
stunned in the ringing silence. Just then two Canada geese flew
overhead and punctuated
the dialogue with, "Honk! honk!"
