Minerva, Chapter 31 by Bob Murphy
“David!”
Roderick Dupont yelled. He
stood up and waved Mason over to the table where he was sitting with
another man. “Charles,
may I introduce to you David Mason, the finest economist and political
scientist of our generation. David,
this is Charles Emerson, the distinguished biologist.” The
two old men shook hands. “Pleasure
to actually meet you, Dr. Mason,” Emerson said.
“Please join us.” Mason
nodded graciously and sat down. “Did
you just get in?” Dupont asked. “Yes,”
Mason answered. “The boat
dropped me off about a half hour ago.
I just freshened up in my room and strolled out here to see if
anyone were still awake.” “Well,”
Dupont said with a smile, “at this time of night, usually you’ll only
find Charles and myself up. Most
of the other fellows here need to turn in much earlier.” “I’ve
always been a bit of a night owl,” Emerson said.
“I do my best thinking at night.” “As
do I,” Mason said. “So
what were you gentlemen discussing? Far
be it from me to disturb your scholarly pursuits.” “Actually,”
Dupont said, “we were discussing the so-called ‘vulnerable balls’
problem. This week’s seminar
is on Intelligent Design, and so naturally we’re all brushing up on our
evolutionary theo—” “Did
you say Intelligent Design??” Mason asked.
He thought he’d come here to escape
pseudo-scientific garbage. “Hey,”
Dupont said, holding up his hands, “house rules.
Members can propose any topic they like.” “And
who is proposing that we waste our time debating Intelligent Design?”
Mason asked. He knew that
Dupont was a staunch atheist, and assumed that any biologist would be
familiar with the silly anti-evolution arguments. “Oh,”
Emerson said, “Novak. Paul
Novak, the theologian. He got
here about three months ago. For
his last seminar we got bogged down on whether the First Mover solution to
the infinite regress should be considered a point in favor of the
existence of God.” “Don’t
worry David,” Dupont said, laughing.
“The other seminars are all completely rigorous.
And as far as theologians go, Novak’s not bad.” “You
will forgive me if I reserve judgment,” Mason said.
“But I am certainly not averse to exploring evolutionary theory.
What exactly were you discussing?” “It’s
called the ‘vulnerable balls’ problem,” Emerson said.
“You know: why would it ever be adaptive for a creature to expose
its sexual organs the way human males and certain other mammals do?
Why aren’t the testicles carried inside the body for protection,
instead of dangling in a defenseless sack?” “And
I was saying, just when you came in,” Dupont said, “that I thought it
might have something to do with keeping the sperm warmer than the rest of
the body.” “Actually,”
Emerson said, “the testicles themselves are kept cooler than the rest of
the body’s interior. But
your suggestion, though a good one, isn’t the currently accepted
explanation.” “What
is it, then?” Dupont asked. “Well,”
Emerson said, “the prevailing theory is that it acts as a signal to
females. It’s the same
explanation as the peacock’s plumage:
Although it is not advantageous by itself, the fact that the males
have such a handicap and yet survive indicates to potential mates that
their other qualities must be superlative.” “I
have always considered that a cop-out,” Mason said.
“You can explain anything that way; even apparent weaknesses get
turned into strengths, and Darwinism becomes non-falsifiable.” “Starting
to sound like Novak,” Dupont joked. “Hold
on a moment,” Emerson said, somewhat taken aback.
“Do you deny that the male’s other traits must compensate for
his vulnerability?” “No
I don’t deny it,” Mason said, “but the male does not simply pass on
those other traits—he passes on his vulnerable balls too.
So when a female sees him, all she can rationally conclude is,
‘This male has managed to survive, and our offspring would have half of
his genetic material.’ That
is precisely what she would conclude by looking at some other male, who
did not have vulnerable balls and managed to survive.” “Oh
come now, Dr. Mason,” Emerson said, “you’re attacking a very
powerful explanatory device in evolutionary theory.” “Yes,”
Mason agreed, “tautologies can be quite useful.” “So
do you even doubt the peacock explanation?” Emerson said, with a hint of
amusement in his voice. He
felt quite relieved that Mason had turned out to be so ignorant in this
area; the man had quite a reputation. “That
one seems more plausible,” Mason admitted, “because it is so clearly
related to a signaling mechanism. I
imagine one could come up with a reasonable model in which the superior
males efficiently invest some of their resources in plumage, because
it’s easier for females to distinguish bright from lackluster feathers
than it is to monitor a male’s ability to evade predators.
In this respect, it is analogous to a human female being attracted
to the big spender at a cocktail party.
What I am objecting to is the knee-jerk invocation of sexual
selection whenever we find an apparent handicap in nature.” “And
what is your explanation for
vulnerable balls?” Emerson asked. “Let
me think a moment,” Mason said. Dupont
and Emerson sipped from their tea—now lukewarm—while Mason stared into
space. “You
will think me a hypocrite,” Mason said, “because I have come up with a
sexual selection answer myself. But
since we are dealing with sexual
organs, I think it’s appropriate.” “Fine,”
Emerson said, amused. “So
what’s your theory?” “I
wonder,” Mason said, “if it might have something to do with the fact
that the testicles are the one weak spot of a human male.
In other words, it’s not merely that exposed testicles make the
male worse in an absolute sense; but it also is the only thing that gives the female a chance in a physical
confrontation. So perhaps the
female is attracted to a male with ‘vulnerable balls’ because she
knows she can discontinue future copulation if she wishes, whereas this
would be almost impossible against a male with protected testicles.” “Very
interesting,” Emerson said. “Now
let’s draw some empirical implications from your explanation and see if
they agree with Nature . . . .” *
* * “So
do the children participate in the seminars?” Mason asked Dupont.
Emerson had long since retired to bed. “No
David,” Dupont said, shaking his head.
“They would be much too boring.” Mason’s
eyebrows shot up. “David,”
Dupont said, choosing his words carefully, “just wait until you meet
Nicodemus. Then you’ll start
to understand.” “He
was the first?” Mason asked. “Yes,
Nicodemus is the oldest jeneer. He
welcomes all of the academics when they first arrive.
He’s the most sociable of the jeneers.” “What’s
he like?” Mason asked. “I
assume he’s incredibly intelligent.” Dupont
threw back his head and laughed. “David,”
he said, “you won’t believe it until you meet them.
And I won’t talk further about it—you’ll see for yourself.
But I suppose it wouldn’t hurt to tell you one thing, to give you
time to prepare.” “What’s
that?” Mason asked. “After
meeting Nicodemus, you will see Ludwig—” “Ludwig?”
Mason asked in surprise. “Yes,
I think his parents were fans of Wittgenstein,” Dupont explained.
“Ludwig is by far the smartest of the lot.
His DNA was based on samples from Einstein’s brain and a few
others. Anyway, you get to ask
him one question.” “What
do you mean?” Mason said. “I
mean,” Dupont said, unable to restrain a large grin, “that after you
chit-chat with Nicodemus, you get to ask Ludwig any one question.” “About
what?” Mason asked. “Anything,”
Dupont said, now smiling even more broadly. “And
then what happens?” Mason said. He
didn’t know why, but he felt . . . creepy. “And
then Ludwig answers it,” Dupont said. Try as he might, Mason couldn’t avoid feeling a chill run down his spine. He noticed that his arms were flush with goosebumps. “What
did you ask him?” Mason asked softly. “I’m
a philosopher,” Dupont said. “I
asked him, ‘Why?’” Excellent,
Mason thought. Thus far, the
two best answers he had heard to this most famous of questions were,
“Because,” and “Why not?” “What
did he say?” Mason asked, even more softly. “‘Why?’”
Dupont answered. Dupont
smiled. “I
imagine you’re going through the same thought process that I did when he
said that to me. But believe
me, David, his answer was the best I could’ve received.
It will keep my puny little mind busy for the rest of my days here.
Because if you try to answer it—if you try to explain why
it is that you want to know, ‘Why?’, then you start to come up
with a pretty good answer to your original question.” discuss this column in the forum Bob Murphy has a Ph.D. in economics from New York University. He is the author of Chaos Theory and has a personal website. |
