There is new evidence in The Journal of Geology which suggests the origin of the catastrophe discussed in the previous post--the Younger Dryas big freeze 13,000 years ago--was not volcanic but "extraterrestrial", that is, an impact by something from space, an asteroid or the like.
The evidence comes from that same thin layer of stuff which is found a few yards down all over the world. The initial small, random sample set did suggest volcanic debris, but over the years a larger sample set has been accumulated which shows differences among regions, and further study found a region--roughly including most of North America, some of South America, and some of Western Europe--which included in the layer an increased abundance of materials such as melt glass, carbon nano-particles, and nano-diamonds, all of which discount the volcanic theory, and suggest the impact theory.
Once again, when we think we have it figured out, we don't. But now we do. This time it is different.
So, now we attribute the sudden extinction of the
great fauna to an asteroid. We used to think it was due to a volcanic
eruption. Before that, we used to think it was on account of predatory paleolithic
hunters; the self-righteous used to beat us up about that. So, yay for
volcanoes and asteroids. Let's see you blame Men for those!

The warp and the woof-woof-woof
Tracing threads of intellectual thought in the tapestry of history.
Twelve thousand nine hundred years
ago (about 11,000 BC) there was a massive die-off of the great fauna of the
Pleistocene era— the wooly mammoths and giant bison and saber-toothed tigers
and great bears and giant sloths and such-like, as well as vast teeming herds
of other things, the ancestors of deer and elk and caribou and all the other
smaller animals that co-existed at that time. In North America, these were the great animals
that the migrating hunters from across the Bering land bridge depended upon for
their living, and they all died off in a relatively short space of time, all
together.
In the 1980s, archeologists
speculated that the migrating humans killed them all off, since everybody knows
human beings are the rapacious ones who destroy their own environment, pollute
the atmosphere, cause entire species to become extinct, and create global
warming.
Could this be right? Or was this just political correctness in
academe?
The fields of archaeology and
paleontology (not to mention history) seem to suffer more than their share of
political correctness. For example,
there was a period of time during the 1970s and ‘80s when
archaeo-paleontologists claimed the evidence demonstrated that human cultures
had once been matriarchal and consequently peaceful, and that at certain times
and places identifiable by archeological debris human societies became
patriarchal, and at the same time became violent towards themselves and others,
and toward the environment. This
field-wide assumption lasted for over a generation, nearly the entire academic careers
of some of its advocates. It is no
coincidence that this interpretation came at the flowering of the feminist
movement in this country. If modern men
were under assault from feminists, ancient men were, too.
Finally, the practice of peer
review revealed the error, and there was a great deal of denial, gnashing of
teeth, bitter recrimination and upheaval within the universities among these scholars
but finally as time went on the error was left behind and it was replaced with
a more rational set of assumptions and a more informative and intellectually
viable analysis regarding patriarchies and matriarchies and social
relationships among cultures.
What had happened was that a
generation of paleontologists had grown up, been educated, and took their
degrees in an era of American culture that placed social responsibility above
rational thought; that found ultimate value in an ideal concept of human
society—and this ideal was not only something toward which a society might
strive in the here and now, but it was also something from which the human
family had once strayed (or so these academics wished to think).
It replicated, if you think about
it, the Biblical myth of the expulsion of Adam and Eve from the Garden of
Eden. One does not have to be a
Christian or to believe in the Bible to recognize that this story when taken at
face value describes the greatest catastrophe of all human history. Never mind the putative threat to the human
soul; the Garden myth describes two things: first, it describes Mankind’s
natural and proper state as existing blissfully in a condition of innocent
non-violence; and second, it describes Mankind’s separation from that state.
There has developed in European
culture since the Enlightenment and in American culture since the end of World
War Two an intellectual following that describes and seeks Utopia as a secular
version of The Garden. Lately, this
trend blames either human beings generally, or Western Civilization itself, or
even more specifically the United States of America as the wretched culprit
that is to blame for either causing this separation from innocence, or for
keeping all of humankind from achieving that desired state here and now.
The influence this general utopian
view has on contemporary thought processes can be traced easily--from PETA to
Fritjof Capra’s movie version of his book The Turning Point to Al Gore’s
championing of Global Warming. And it was
demonstrably found among the practitioners of the scholarly fields of
Paleontology and Archaeology. It should
be of interest to us how long this influence lasted in a field allegedly partaking
of scholarly rigor, and how long it took for that very same rigor in the form
of peer review to overcome the error.
We should, I suppose, be grateful
that the error was overcome at all. The
persistence of such an egregious error in a scholarly field attests to the
strength and power of its underlying cause—political correctness and a general
loathing of American culture by American academe—but more to the point for us
here and now is just to have an awareness that such things can actually
happen. One must be a bit more alert than
usual in order to spot it, however.
Academics tend to be convinced of the rightness of their analyses, to
write persuasively about them, and to defend them vigorously among their
colleagues. When these ideas emerge into
the popular culture, they take on the appearance of something that Always Has
Been True.
Let us return now to our original
thesis regarding the die-off of the Pleistocene-era fauna. This group of animals was terrifically
varied, included some very large, vigorous and dangerous animals. They populated the North American Continent
in much the same way that the buffalo did in later centuries—in unbelievably
vast numbers. Paleolithic humans hunted
them in the same way the pre-Columbian Indians hunted the buffalo—on foot. Modern scholars of this field felt they could
prove that the ancient humans hunted those animals—all of them—into
extinction. It never occurred to them to
wonder why, then, if mankind was so rapacious, that the Native American Indians
in their turn had not hunted the buffalo (American Bison) into extinction. The answer to that, if you think about it
from a practical standpoint, is that primitive cultures could not
exterminate entire species let alone all the fauna on an entire continent. They simply did not have the numbers or the
mechanisms with which to accomplish such a feat, even if they had wished
to. Of course, the scholars never quite
made that claim—that the Pleistocene humans wanted to wipe out their source of
food. No, they just did it [so the
argument went] because that’s the way they were—rapacious and thoughtless, the
ultimate conspicuous consumers of the Earth’s bounty, the ultimate mindless
killing machine.
As it turns out, this thesis was
wrong and eventually the error was corrected.
But it was neither common sense nor peer-review that brought the field
around to an evidence-based reality. It
was another science entirely. Just a few
years ago, geologists discovered a peculiar layer of dirt sandwiched within the
innumerable layers of dirt interleaved one upon the other all over the
planet. Such curious planet-wide layers
are not unknown. There is another, more
famous layer which is found everywhere, and wherever it is found is reliably
dated to about 60 million years ago—the time the dinosaurs disappeared. That thin layer contains iridium, and is now
seen as evidence of the impact of a great meteor which wiped out the dinosaurs in
a meteoric equivalent of a nuclear winter.
The younger, similar layer just
recently found consistently corresponds to the time frame we associate with the
great Pleistocene die-off—about 12,900 years ago. Research into the composition of this layer now
indicates that it records an event of terrestrial volcanic origin, and it is
clear that the event was of sufficient magnitude that it very likely caused the
die-off of the great mammals, rather than over-hunting by primitive tribes of
humans. A big volcanic gush filled the
atmosphere with ash, dimmed the sun, brought on a sudden planet-wide cooling
event which killed the animals.
Yet, paleontology had insisted for
years that it was the rapacious cave-man that was the culprit. Once again, paleontology led us astray, and
the rigor of other sciences has forced the peer review process to bring us
around to the right path.
Careful thought here will suggest
that the description of ancient man as a rapacious predator is actually a
contemporary commentary on present man.
It ceased to be archaeo-paleontology and became modern social
commentary. That it wrongly describes
ancient man should also help us to entertain the possibility that it also
wrongly describes present man, although the jury is still out on that one.
That conception of mankind was part
of an intellectual thread which is found first in the 19th century Utopians’
analysis. Now we’ve traced this thread
to other fields of study. Now that you
know what it looks like, you can look for it elsewhere as you study the
tapestry of your own world, if you wish.

Literacy and its absence
The problem with literacy is that
the poorly educated do not automatically revert to a pre-literate state. On the contrary. A pre-literate person was obliged habitually
to exercise his memory and imagination.
An illiterate person has neither skill.
I’ve just spent several hours correcting the assignments of
semi-literate high school graduates who are now college freshmen. It is late.
I am discouraged. My own
institutions—a small state university and a considerably larger community college—have
demonstrated once again that their primary entrance requirements are a pulse
and a credit card. I am beyond
discouraged.
Failure of conventional wisdom
This dialog from Serenity illustrates the failure of
conventional wisdom:
OPERATIVE: It’s
worse than you think.
MAL: It usually
is.
Today’s lesson: It is worse than
you think.
It is worse than most observers think.
In fact, conventional wisdom has
underestimated this economic problem from its beginning. To wit: in 2007, Ben Bernanke asserted that
the subprime mortgage crisis was contained. Events demonstrated his error. In
2009, Moody’s Investor Services claimed that investors’ fears that Greece was in
a liquidity crisis were misplaced.
Events demonstrated their error.
During most of 2011, European
leaders, most notably Sarkozy of France and Merkel of Germany, put forward plan
after plan whose purpose was to solve the European debt problem. Events proved each inadequate. Each reassured the major markets, but only for
a few weeks or days; each in turn failed to resolve underlying market
issues. Whereupon the European leaders
would meet once again, devise a new plan, with similar results. This has happened about a dozen times this
year[1],
and the only result is that stability has been sustained, but just barely. We may rejoice that there has only been
rioting in Athens and London, and that it has not gotten worse so far.
Two lessons emerge: conventional
wisdom is not wise, one, and two, plan after plan after plan is not a plan. Or
to put it in other words, keeping the rioting down to a dull roar is not
success. Or, to put it in still other
words, if the success of today’s plan is measured by how it limits social
unrest, then we must not have unreasonable expectations that tomorrow’s plan
will actually address underlying systemic problems.
So, what next? For me, I must
shake my well-entrenched conviction that “it will all work out in the end, as it
has all my life.” After all, I used to
worry that nuclear war was possible. It
was and still is, but so far it has worked out.
I worry now that economic catastrophe is imminent. My inclination is to say, “it will work out.
I personally won’t be inconvenienced very much, let alone endangered.”
This is wishful thinking, a
category of thought which has gotten many people killed. History demonstrates
that repeatedly.
Congress has failed as well. The
failure of the “Super Committee” triggers automatic budget cuts to the tune of
$1 trillion. That seems large, but it is
stretched over nine years, which means in actuality cuts of a little over $100
billion a year. And they won’t begin until 2013 (after the election). Meanwhile federal debt increases that much every month. And one last remark about this—curiously, and
in the face of evidence to the contrary—the plan also expects $169 billion in
savings from lower costs of borrowing, which under the circumstances of
near-zero interest rates is a laughable assumption.
Therefore, we must accept that
Congress is not capable of being effective about this.[2]
One historical example of a
democratic representative body being incapable of effective action on
intractable problems may be found in inter-war Italy, with the consequences you
should have learned in your world civ class.
I can elaborate if you wish. The short version is that it created a
vacuum of power into which stepped the man on horseback, the strong man, Il
Duce, Mussolini.
This is not necessarily always the
consequence, however. A wonderful line
from Robert Merle’s novel, Malevil,
illustrates this:
“I do not believe
for a moment that a group, on whatever scale, always produces the great man it
needs. Quite the contrary. There are moments in history when one senses
a terrible void. The necessary leader
has not appeared, and everything goes lamentably wrong.”
Thus: It is worse than you
think.
Or as expressed in Serenity:
RIVER TAM: Things are going to get much, much worse.

[1] As of
March 2013, that number amounts to precisely 20, and the result is the same.
[2] As of
July 2013, the dreaded automatic budget cuts have occurred, even though they
were not supposed to happen because they were so terrible to contemplate that the
Congress which sat after the Super Committee’s work was done was supposed to
fix the systemic problems which the Super Committee only kicked down the
road. Well, the subsequent Congress did
not fix the problems, the budget cuts occurred to great wailing and gnashing of
teeth, the administration fiddled with them enough to make them seem
oh-so-terribly painful to the public, and now some months later nobody is
talking about them. It was all Kabuki
Theater -- Congressional failure and Executive spitefulness.
