<p>Penfield twirled the stem of his port-glass between thumb and
finger.</p>
<p>“I don’t agree,” he said. “It’s nothing but egocentric vanity to
consider our form of life as unique among those on the millions of
worlds that must exist.”</p>
<p>“How do you know they exist?” said Hodge.</p>
<p>“Observation,” said McCall. “The astronomers have proved that
other stars beside our sun have planets.”</p>
<p>“You’re playing into his hands,” observed Penfield, the heavy
eyebrows twitching as he cracked a nut. “The statistical approach
is better. Why doesn’t this glass of port suddenly boil and spout all
over the ceiling? You’ve never seen a glass of port behave that way,
but the molecules that compose it are in constant motion, and any
physicist will tell you that there’s no reason why they can’t all decide
to move in the same direction at once. There’s only an overwhelming
possibility that it won’t happen. To believe that we, on
this earth, one of the planets of a minor star, are the only form of
intelligent life, is like expecting the port to boil any moment.”</p>
<p>“There are a good many possibilities for intelligent life, though,”
said McCall. “Some Swede who wrote in German—I think his name
was Lundmark—has looked into the list. He says, for instance, that
a chlorine-silicon cycle would maintain life quite as well as the oxygen-carbon
system this planet has, and there’s no particular reason
why nature should favor one form more than the other. Oxygen is
a very active element to be floating around free in such quantities
as we have it.”</p>
<p>“All right,” said Hodge, “can’t it be that the cycle you mention
is the normal one, and ours is the eccentricity?”</p>
<div class="pagenum" id="Page_226">226</div>
<p>“Look here,” said Penfield, “what in the world is the point you’re
making? Pass the port, and let’s review the bidding.” He leaned
back in his chair and gazed toward the top of the room, where the
carved coats of arms burned dully at the top of the dark panelling.
“I don’t mean that everything here is reproduced exactly somewhere
else in the universe, with three men named Hodge, McCall and
Penfield sitting down to discuss sophomore philosophy after a sound
dinner. The fact that we are here and under these circumstances is
the sum of all the past history of—”</p>
<p>Hodge laughed. “I find the picture of us three as the crown of
human history an arresting one,” he said.</p>
<p>“You’re confusing two different things. I didn’t say we were elegant
creatures, or even desirable ones. But behind us there are
certain circumstances, each one of which is as unlikely as the
boiling port. For example, the occurrence of such persons as
Beethoven, George Washington, and the man who invented the
wheel. They are part of our background. On one of the other
worlds that started approximately as ours did, they wouldn’t exist,
and the world would be altered by that much.”</p>
<p>“It seems to me,” said McCall, “that once you accept the idea
of worlds starting from approximately the same point—that is,
another planet having the same size and chemical makeup, and
about the same distance from its sun—”</p>
<p>“That’s what I find hard to accept,” said Hodge.</p>
<p>“Grant us our folly for a moment,” said McCall. “It leads to
something more interesting than chasing our tails.” He snapped his
lighter. “What I was saying is that if you grant approximately the
same start, you’re going to arrive at approximately the same end,
in spite of what Penfield thinks. We have evidence of that right
on this earth. I mean what they call convergent evolution. When
the reptiles were dominant, they produced vegetable-eaters and
carnivores that fed on them. And among the early mammals there
were animals that looked so much like cats and wolves that the
only way to tell them apart is by the skeleton. Why couldn’t that
apply to human evolution, too?”</p>
<p>“You mean,” said Penfield, “that Beethoven and George Washington
would be inevitable?”</p>
<p>“Not that, exactly,” said McCall. “But some kind of musical
inventor, and some sort of high-principled military and political
leader. There might be differences.”</p>
<div class="pagenum" id="Page_227">227</div>
<p>Hodge said: “Wait a minute. If we are the product of human
history, so were Beethoven and Washington. All you’ve got is a
determinism, with nothing really alterable, once the sun decided to
cast off its planets.”</p>
<p>“The doctrine of free will—” began McCall.</p>
<p>“I know that one,” said Penfield. “But if you deny free will completely,
you’ll end up with a universe in which every world like ours
is identical—which is as absurd as Hodge’s picture of us is unique,
and rather more repulsive.”</p>
<p>“Well, then,” said Hodge, “What kind of cosmology are you
putting out? If you won’t have either of our pictures, give us
yours.”</p>
<p>Penfield sipped port. “I can only suggest a sample,” he said.
“Let’s suppose this world—or one very like it—with one of those
improbable boiling-port accidents left out somewhere along the
line. I mentioned the wheel a moment ago. What would life be like
now if it hadn’t been invented?”</p>
<p>“Ask McCall,” said Hodge. “He’s the technician.”</p>
<p>“Not the wheel, no,” said McCall. “I can’t buy that. It’s too
logical a product of the environment. Happens as soon as a primitive
man perceives that a section of tree-trunk will roll. No. If
you’re going to make a supposition, you’ll have to keep it clean,
and think in terms of something that really might not have happened.
For example, music. There are lots of peoples, right here,
who never found the full chromatic scale, including the classical
civilizations. But I suppose that’s not basic enough for you.”</p>
<p>For a moment or two, the three sipped and smoked in the unspoken
communication of friendship. A log collapsed in the fireplace,
throwing out a spray of sparks. McCall said: “The steam
engine is a rather unlikely invention, when you come to think of
it. And most modern machines and their products are outgrowths
of it in one way or another. But I can think of one more peculiar
and more basic than that. Gunpowder.”</p>
<p>“Oh, come,” said Hodge, “that’s a specialized—”</p>
<p>“No it isn’t,” said Penfield. “He’s perfectly right. Gunpowder
destroyed the feudal system, and produced the atmosphere in
which your steam engine became possible. And remember that
all the older civilizations, even in the East, were subject to
periodic setbacks by barbarian invasions. Gunpowder provided
civilized man with a technique no barbarian could imitate, and
helped him over the difficult spots.”</p>
<p>McCall said; “All the metal-working techniques and most of
chemistry depend on the use of explosives—basically. Imagine
digging out all the ores we need by hand.”</p>
<div class="pagenum" id="Page_228">228</div>
<p>“All right, then,” said Hodge, “have your fun. Let’s imagine a
world like this one, in which gunpowder has never been invented.
What are you going to have it look like?”</p>
<p>“I don’t know,” said McCall, “but I think Penfield’s wrong
about one point. About the feudal system, I mean. It was pretty
shaky toward the end, and the cannon that battered down the
castles only hurried up the process. There might be a lot more
pieces of the feudal system hanging around without gunpowder,
but the thing would be pretty well shot.”</p>
<p>“Now, look here,” said Hodge. “You’ve overlooked something
else. If you’re going to eliminate gunpowder and everything that
came out of it, you’ll have to replace it with something. After all,
a large part of the time and attention of our so-called civilization
have been spent in working out the results of the gunpowder and
steam engine inventions, If you take those away, you’ll have a
vacuum, which I’m told, nature abhors. There would have to be a
corresponding development in some other field, going ’way beyond
where we are.”</p>
<p>Penfield drank and nodded. “That’s fair,” he said. “A development
along some line we’ve neglected because we have been too
busy with mechanics. Why couldn’t it be in the region of ESP,
or psychology or psychiatry—science of the mind?”</p>
<p>“But the psychologists are just operating on the ordinary principles
of physical science,” said McCall. “Observing, verifying
from a number of examples, and then attempting to predict. I don’t
see how another race would have gone farther by being ignorant
of these principles or overlooking them.”</p>
<p>“You’re being insular,” said Penfield. “I don’t mean that in
another world they would have turned psychology into an exact
science in our terms. It might be something altogether different.
Your principles of science are developed along the lines of arithmetic.
The reason they haven’t worked very well in dealing with the
human mind may be because they aren’t applicable at all. There
may be quite a different line of approach. Think it over for a
moment. It might even be along the line of magic, witchcraft.”</p>
<p>“I like that,” said McCall. “You want to make a difference by
substituting something phoney for something real.”</p>
<p>“But it might not be phoney,” insisted Penfield. “Magic and
witchcraft are really pretty late in our world. They began to be
talked about at the same time and on the same terms as alchemy,
everything surrounded by superstition, lying and plain ignorance.
In this world we’re imagining, somebody might have found the
key to something as basic in that field as gunpowder was to the
physical sciences. Some people say we almost made the discovery
here. You know the story about this house?”</p>
<div class="pagenum" id="Page_229">229</div>
<p>McCall nodded, but Hodge said: “No. What is it? Another
ghost story?”</p>
<p>“Not quite. The old part of the house, the one where the bedrooms
are now, is supposed to have been built by one of the Salem
witches. Not one of those they hanged on false charges, but a perfectly
genuine witch, who got away before she was suspected—as a
real witch probably would. The story is that she came here and set
up business among the Indians, and as they weren’t very expert at
carpentry, she helped them build that part of the house with spells,
so it would be eternal. The old beams haven’t a bit of iron in them;
they’re all held together with pegs and haven’t rotted a bit. There’s
also a story that if you make the proper preparations at night, something
beyond the normal will happen. I’ve never done the right
thing myself, apparently.”</p>
<p>“You probably won’t,” said Hodge. “The essence of the whole
witchcraft business is uncertainty. Haven’t you noticed that in all
the legends, the spells never quite come off when they’re needed?”</p>
<p>“That’s probably because there isn’t any science of witchcraft,
with predictable results,” said McCall.</p>
<p>Penfield said: “It may be for another reason, too. Have you ever
noticed that magic is the only form of human activity which is
dominated by women? The really scary creatures are all witches;
when a man becomes a magician, he’s either possessed of a devil
or is a glorified juggler. Our theoretical world would have to start
by being a matriarchy.”</p>
<p>“Or contain the relics of one,” said Hodge. “Matriarchies are
socially unstable.”</p>
<p>“So is everything,” said McCall. “Flow and change from one
form to another is a characteristic of life—or maybe a definition of
life. That goes for your witchcraft, too. It would change form,
there’d be resistance to it, and an effort to find something to replace
it.”</p>
<p>“Or to remove the disabilities,” said Hodge. “The difficulty with
any power we don’t really know about is not to define the power
itself, but to discover its limitations. If witchcraft were really practical,
there would be some fairly severe penalties going with it, not
legally I mean, but personally, as a result of the practice. Or to put
the thing in your terms, McCall, if there weren’t any drawbacks,
being a witch would have such high selection value that before long
every female alive would be a practicing witch.”</p>
<div class="pagenum" id="Page_230">230</div>
<p>McCall carefully poured more port. “Hodge,” he said, “you’re
wonderful, and I love you. But that’s typical of the way you put
things. You cover up a weak point by following it with one that
attracts everyone’s attention away from the feebleness of your real
case. Penalties for everything? What’s the penalty for having an
electric icebox?”</p>
<p>“A pampered digestive system,” said Hodge, readily. “I doubt
whether you could survive the food Queen Elizabeth ate for very
long, but she lived to be well over sixty. If there were witchcraft,
or ESP or telepathy running around in the world, there couldn’t
but be defenses against it and troubles for the practitioners. Had
it occurred to you that even a witch couldn’t spend all her time
stirring cauldrons, and might want to lead a normal life, with a husband
and children?”</p>
<p>Penfield got up and stepped to the window, where he stood
looking out and down at the midnight Atlantic, throwing its surges
against the breast of the rocks. “I wonder if it really does exist,”
he said.</p>
<p>Hodge laughed; but that night all three men dreamed: and it
was as though a filament ran through the ancient rooms; for each
knew that he dreamed, and dreamed the same dream as the others;
and from time to time tried to cry out to them, but could only see
and hear.</p>
