If I had a TARDIS, I'd...
Somebody really needs to get their act together and invent time travel.
No, really. In between doing the job search thing and getting a few other things done today, I got to thinking about how cool it would be to be able to hop around in time and witness past events. And then I got to thinking about it some more and soon realized that most of the things I want to go back and see aren't discrete historical events - moments in history, or even the things you traditionally find in the history books. Instead, they are processes, many of them, events that happened over a period of time and that have had an impact, but not necessarily on war, politics, and economics - all those drivers of academic history.
I shouldn't really be surprised by that. I chose to major in anthropology rather than history, and I'm really fascinated with how people get along and how they do things, individually and in groups. As I think I've mentioned here recently, process is a big thing for me. There are a few more traditionally historical things that I'd like to go back and see about, but there were also some very pop-culture things that turned up on the quick list of ten that I drew up. I imagine that if I took more time, there would be a list that's a lot longer than this, but these are the 10 that came immediately to mind, starting with the less traditionally historical entries:
1) Opening day at Disneyland.
Not the famously disastrous "Press Preview" day on July 17, 1955, but the next day, the real opening, when people started lining up at something like 2 a.m. to get in to see Disney's newest production. I've always loved Disneyland (for all that I was chided once for that love and told that liking Disneyland is not "sophisticated"), and it would be so cool to see what it was like at the beginning, before it expanded and turned into the icon that it is today.
2) A Beatles concert.
Preferably the one that appears in the movie "Let It Be", the final time all four Beatles performed live in public together. That was on January 30, 1969, on the roof of the headquarters of Apple Records. But any Beatles concert would do, because it just isn't right that I never got to see The Beatles perform live.
3) The recording sessions for "Pet Sounds".
I've been watching some documentary footage recently of the sessions for this Beach Boys album, considered by many to be one of, if not the, greatest pop album ever made. Fascinating. I don't think all those people who call Brian Wilson a genius are just engaging in hyperbole. Clearly, Wilson hears things that the rest of the world doesn't, and that he managed to get those successfully on record is miraculous (especially since he is deaf in one ear), and I'd love to be able to witness that genius at work. Because they were done the same year, I'd like to also include in this the "Good Vibrations" sessions, which were a continuation of Wilson's experimentation on "Pet Sounds".
And now, on to the more historical events that appear on the list:
4) Mission control during the flight of Apollo 11.
Yeah, I'm a space geek. I proved that a couple of weeks ago when I visited the Air and Space Museum at the Smithsonian, and burst into tears several times at the things I saw there there. I've seen some film of operations in mission control at Johnson Space Center in Houston during that mission, and I would love to have the experience of seeing that first moon landing from where the flight was being directed.
5) A meeting of England's Queen Elizabeth I with her Privy Council.
Elizabeth I must have been one hell of a woman, running a country at a time and place in history where women were just not expected to do that sort of thing. I'd love to see how she handled the responsibility - and the men who had to acquiesce to her as queen.
6) One of Savonarola's sermons around the time he came to power as the de facto dictator of Florence in the mid-1490s.
I'm really curious about how that ugly little monk (sorry, I've seen paintings, and if they are at all accurate, the poor man was one of the least attractive individuals who ever lived) was able to impose his will on the home of the Renaissance for a bit over two years after delivering a series of fire-and-brimstone, prophecy-laden sermons to the population of the city. Hell, even Botticelli burned some of his artworks in Savonarola's "bonfires of the vanities" after hearing his sermons. Michelangelo, thank goodness, wasn't as swayed by the monk's admonitions. Savonarola finally overstepped in his ambitions when he started preaching reform. Pope Alexander VI excommunicated Savonarola and put Florence under an interdict as long as they harbored him. That was bad news for Savonarola, since instead of just kicking him out of town, Florence had him and two of his fellow monks burned at the stake. The thing I'm interested in, in all this, is how Savonarola managed to work his way into power in the first place.
7) Michelangelo painting the Sistine ceiling.
Just about the time that Savonarola was coming to power in Florence, Michelangelo left his home city for Rome. He returned to Florence to carve his David after having sculpted the his Pieta that stands today in St. Peter's Basilica in Rome. Once again in Rome, summoned by Pope Julius II to carve the Pope's tomb, Michelangelo found himself instead assigned to paint the ceiling of the Sistine Chapel. He resisted, insisting that he was a sculptor and not a painter. But those were the days when you really didn't say no to the Pope, and over four years, from 1508 to 1512, Michelangelo created one of his most cherished masterpieces. Of course, he made things more difficult on himself by designing a much more ambitious series of frescoes than the pope had asked for, but that was Michelangelo for you. I would love to be able to witness the process that resulted in such beauty.
8) The building of the Great Pyramid at Giza.
Well, yeah. It's the Great Pyramid. Every once in a while, someone says that they've figured out how the Egyptians lifted all those heavy, heavy blocks to build that pyramid, but I would like to see for myself exactly how it was done. Because, you know, I don't buy the story that it was aliens.
9) Life in what is now the US southwest during the time when the Pueblo peoples were building and living in those giant apartment buildings they created.
There's more to it than just the cliff dwellings such as those at Mesa Verde in what is now Colorado and freestanding apartment buildings like Pueblo Bonito in New Mexico. There were the roads that supported a wide trade and indications that they traded even outside the region and into Mexico, over a thousand miles away. This was a complicated culture, and I would love to see how those communities were built and sustained in such a difficult environment.
10) The United States Constitutional Convention in Philadelphia in 1787.
I get tired sometimes of hearing politicians talking about the original intent of the framers of the US Constitution. I would like to see for myself exactly what was said in those meetings, and in the after-meetings where the framers probably said what they were really thinking. But, again, I need a time machine to do that.
The truth is, if I made this list again tomorrow, or had made it yesterday, it would be different than this list. Probably not completely different, because at least a few of the entries are non-negotiable, at least today. No, I'm not telling which ones. And as I said at the beginning of this, if I had taken more time to think about it, this list would probably be a lot longer.
The thing I'd like to know now is, if you made a list like this, what events would you put on it? Why would you choose those events? Please, if you feel so inclined, drop a comment about what your list would include. Or, if you use this question as a prompt for a blog post of your own, please drop a comment and link so that I can read it.

History, geology, and calendars, oh, my...
I love it when different events in different years but on the same day have a resonance of some kind with each other.
Today is one of those days. Well, depending on which calendar you use, but still...Let me tell you a story.
Nicolas Steno was born on this day in 1638. Kind of.
The Gregorian Calendar, the calendar we use today, was decreed by Pope Gregory XIII in 1582, and was pretty much immediately adopted by the European Catholic countries. However, Denmark, where Steno was born, was a Lutheran country and so kept on using the Julian Calendar and resisted adopting Gregory's calendar until March 1, 1700. So, according to the calendar used when and where he was born, Steno was born on January 1. But, not only because we use the Gregorian Calendar today but because Steno converted from Lutheranism to Roman Catholicism (in 1667), it is appropriate to mark his birthday on January 11.
Before his conversion and ordniation to the priesthood, Steno had studied both anatomy and geology. Besides having taught anatomy, he is considered to be one of the founders of modern geology. In 1669, published a work in which he recognized the basic principles of stratigraphy, the basis of all modern geological studies. These were 1) the law of superposition, which says that in undisturbed geolgoical layers, the lower strata are older than higher strata; 2) the principle of original horizontality, the idea that tilted strata were horizontal at their deposition; and 3) the principle of lateral continuity, which says that material in a stratum was continuous unless a solid body stood in the way. He also recognized the principle of cross-cutting relationships, the idea that a discontinuity or body that intrudes into a stratum is younger than the stratum, as well as articulating the theory that fossils represent the remains of life in different geolgical eras.
Today in the Roman Catholic church, Steno is known as the Blesssed Nicolas Steno, having been beatified, the last step before sainthood, by Pope John Paul II in 1988. I don't know if that status makes Steno unique among scientists, but I'm pretty sure there are not that many scientists on their way to sainthood.
But that isn't what makes the fact that today is Steno's birthday interesting to me. What makes it interesting to me is the fact that January 11, in 1908, is the day that Grand Canyon National Monument was created. It had been named Grand Canyon Game Preserve in 1906, but would not be created as a national park until 1919.
Nicolas Steno would have loved the Grand Canyon, considering that it contains one of the most complete geologic columns in the world. This is true even though down near the bottom of the canyon there is what is called the Great Unconformity. At that point, there is a gap of around one billion years between rocks that are 1.5 billion years old and rocks that were depostied about 500 million years ago. The Unconformity represents a period of erosion between depositions.
Can you imagine how much fun Steno would have had studying all those strata in the Canyon? It seems to me that there is some sort of poetic justice in the Canyon being created a national monument on the 270th anniversary of Steno's birth.
Which only goes to prove, I suppose, that I am both a science geek and a history geek, and that if I try really, really hard, I can manage to combine them.

Autumn is here...and a short review of the history of September 22
It's the first day of autumn. Or, if you are in the Southern Hemisphere, the first day of spring.
So, of course, there are reports of snow in parts of Minnesota and Wisconsin. According to Weather.com, this snow, which is enough to stick in some places, is about a month earlier than its usual first appearance, based on long-term averages. On the other hand, it's sill in the 80s and 90s in the southern tier of states, and the predicted high in Phoenix, Arizona for today was 107 degrees Fahrenheit, with 101 degrees predicted a bit farther south, in Tuscon.
Here in my neck of the woods, it was predicted to hit 99 F today, but I don't think it managed to get quite that hot. I wouldn't know. I was only out briefly during the day, well before the hottest part of the day.
Anyway, with it being the autumnal equinox and all, I thought it would be a good day to see what happened on this day in history. So, I wandered over to Wikipedia (which isn't that bad a place, as long as you aren't using it as a source for academic papers, you fact-check what you find there, and you realize that their philosophy is that anything that has been published is an authoritative source) to see what they had to say about what has happened on September 22 through history.
First of all, I found, it is the 266th day of the year; it would have been the 265th day, but this year was a leap year. There are 100 days left in the year. Just what I needed to be reminded of - that Christmas is right around the corner.
There is quite a list of events that happened on this day. A few stood out. On this day in 1692, the last hangings for witchcraft in what is now the United States took place, which serves as a good reminder that religious extremism isn't anything new. But, it does beg the question of why, all these years later, so many people still go to extremes in their religion.
Those are not the only historically notable hangings that happened a September 22: in 1776, on this day, Nathan Hale was hanged as a spy during the American Revolution. General George Washington had asked for volunteers to go behind enemy lines to try to find out where the British were planning on landing in their invasion of Manhattan Island. Hale was the only volunteer. He was captured by the British and hanged at the age of 21. Hale is now the official State Hero of Connecticut, his home state.
There are also other religious events that happened on September 22. In 1823 (or 1822, depending on the source), Joseph Smith said he found the Golden Plates that he claimed to have used to translate the Book of Mormon. There are a few versions of the story, but the general account is that it was on September 22 in one of those two years that he first found the plates, guided by a vision from an angel who said his name was Moroni. Although Smith did not get the plates when he first found them - he said that the angel prevented him from doing so - several years later, in 1827, also on September 22, he was allowed to take the plates and commence his work with them. After he was finished with the translations, so the story goes, the plates were taken from him. So, you know, no physical evidence of them exists. Additionally, there are also several versions of the story of how he translated them to get the Book of Mormon. Honestly, trying to pin down what really happened in Mormon history is like trying to...well, like trying to pin down what position Mitt Romney really holds on an issue.
Maybe we should ask Mitt about the plates. He's Mormon, after all. He served a mission for his church. He might like to get his mind off his campaign for president, seeing how it hasn't been going that well for him lately.
Not related to either hangings or religion, so far as I know, this is the day in 1888 that the first issue of National Geographic Magazine was published. National Geographic has come in for its share of criticism from time to time in the years since that first issue, and not just for its role as young boys' go-to publication for seeing photos of topless women before Playboy got its start. Personally, though, I like National Geographic. It has fed my inner archaeology and anthropology geek since I was very young.
On September 22 in 1896, Queen Victoria surpassed her grandfather, George III (who, of course, was the monarch that the American colonists rebelled against), as the longest reigning monarch in British history. George III reigned for 59 years and 96 days, while Victoria eventually reigned for 63 years and 7 months and remains the longest reigning British monarch and the longest reigning female monarch in history. Queen Elizabeth II is gaining on her, though; Elizabeth has been on the throne for 60 years and a bit over 7 months as of this writing.
Speaking of queens, as we have been - September 22 is the birthday of Henry VIII's fourth wife, Anne of Cleves. Oh, they weren't married for long - just a bit over 7 months - before Henry had the marriage annulled, and she was never officially crowned as Queen Consort. Which makes sense, as it is difficult to be a consort when the marriage was never consummated. But, by virtue of being married to Henry, she was the Queen in practical terms for that time. And in many ways, Anne was the luckiest of Henry's wives. She never had to sleep with him, which had proved dangerous for his earlier queens. He divorced Catherine of Aragon because she couldn't give him a son. He had Anne Boleyn beheaded, supposedly for high treason, although it had a lot to do that she bore him only a daughter and then miscarried a disputed number of times, including the miscarriage of a son. His third wife, Jane Seymour, died of complications of childbirth less than two weeks after giving birth to Henry's son, Edward. Once Henry decided that Anne of Cleves wasn't really a suitable wife for him, he asked her for the annulment, which she wisely consented to. He gave her a substantial settlement, invited her to court often, and was referred to afterward as "the King's beloved sister". Anne outlived Henry's two latter wives, Catherine Howard, who was beheaded for not having disclosed her previous sexual history to the king in a timely manner, which Parliament arranged to have called treason, and Catherine Parr, who survived Henry.
So, all in all, a fairly interesting day in history. At least for us history geeks.

Proving once again that I am, indeed, a geek...
As part of a continuing effort to get a blog centered on history and related topics started, I've been writing some sample posts to try to figure out exactly how I want to approach the new blog.
I started out with the idea that it would be a simple "On this day..." sort of exercise, but I've pretty much decided that the approach is a) too limiting of what I'm aiming to do and b) way too overdone. I'd like to remain open to doing that sort of entry on a regular but not constant basis, but I want it to be more, as well. So, the blog is not ready to go live yet. On the other hand, I've had some interesting experiences in reading and writing the sample posts.
For example, I that today is the fifth anniversary of the demotion of Pluto from planet to dwarf planet. I thought that would be an interesting event to note, and decided to take a quick look to see if I could find out about the story behind the event. What ensued was two-and-a-half or three hours really interesting (to me, anyway) research and the writing of a blog post summarizing what I'd learned.
I had fun with it. I don't want it to go to waste, but since the new blog is not ready to unleash on the world just yet, I thought I'd share it here.
And so, this is what I learned about Pluto, dwarf planets and the International Astronomical Union:
One of the things I most love about history, and about historical events, is that it is possible to start with one event and end up roaming around in any subject area imaginable.
Take the redefinition of the term "planet". On August 24, 2006, the International Astronomical Union (IAU), which is the internationally recognized body given the authority to assign designations to astronomical bodies, redefined - or rather, created an official definition of - the term. Apparently, there hadn't been an official definition previous to this time. By codifing a definion, they read Pluto out of the nine planets of our solar system and into the newly designated classification of "dwarf planet".
I intended to take a quick look to see exactly what that definition was, how a planet differs from a dwarf planet, and why they (perhaps that should be "they") decided that Pluto was not one but the other. It should have taken fifteen or twenty minutes, tops, not least because the Internet is a wonderful thing.
Right? Well, not really. I learned in the course of a couple of hours of research that the redefinition is not as universally accepted as the IAU would have the world think. I also found out some things about the outer reaches of the solar system that are just amazing, and that the picture of that part of our galactic neighborhood is much different from that I learned about as a child entranced by the very idea of outer space.
To begin with, while it seems at first glance as if the category of dwarf planet was engineered mostly to have something to call Pluto once it was removed from the list of planets, it turns out that there are other objects in the category, and that Pluto isn't even the most massive of the four largest of its new kind. It turns out that there are a lot of things and a lot more complexity than was thought to the region beyond Neptune, now the outermost planet since the demotion of Pluto, and that small planet-like objects in that region are called Trans-Neptunian objects. There are, according to some sources, up to 1,200 of these objects. I also discovered that this region beyond Neptune is made up of three areas, which overlap to at least a certain degree.
There is the Kuiper belt, which is similar to the asteroid belt between Mars and Jupiter but twenty times as wide and twenty to two hundred times as massive as the asteroid belt. It extends from the orbit of Neptune to about 55 astronomical units (AU). An astronomical unit, in case you missed science class that day, is the rough distance between the Earth and the Sun, more or less 93 million miles. Then there is the scattered disc, which overlaps and lies beyond the Kuiper belt, which stretches from around 30 to 35 AU from the Sun to well beyond 100 AU from the Sun and reaches well above and well below the plane of the ecliptic, the plane on which the planets orbit around the Sun.
Beyond the scattered disc is the Oort Cloud, which is still a hypothetical construct since there have been no confirmed direct observations of it. The Oort cloud probably reaches out to around 50,000 AU from the Sun, nearly a light year out and almost a quarter of the way to Proxima Centauri, the closest star to the Sun, although some estimates put its outer edge as far as 100,000 to 200,000 AU out. That's a very long way. The objects in the Oort cloud are only loosely bound to the solar system and can be affected by the gravitational influence of passing stars and of the galaxy itself. The objects in this region are mostly icy and likely came into being much nearer the Sun but were scattered by gravitational interaction with the outer, giant planets. It is believed that most long-period comets originate in either the scattered disc or the Oort Cloud.
All of which is very interesting, but I set out to find out about Pluto and why it is no longer considered a planet. Pluto was discovered, officially speaking, on February 18, 1930 by Clyde Tombaugh, from images taken on January 23 and January 29, 1930 at the Lowell Observatory in Flagstaff, Arizona, although it had been seen in other astronomical images at least sixteen times previously, beginning in 1909 at Yerkes Observatory. It was named for the Greek god of the underworld on March 24, 1930.
Because Pluto is so far away, coming as close as just less than 30 AU but going as far away as just less than 49 AU from the Sun, it is difficult to study. It is known that Pluto has four satellites that orbit very near the planet. In fact, its largest moon, Charon, is so large and close (the two are only 12,200 miles apart, less than the distance between London, in the UK, and Sydney, Australia), that the two have been described as a dwarf double planet. Pluto's diameter is about 66 percent that of Earth's Moon and it has a thin atmosphere of nitrogen, methane and carbon monoxide. Some fuzzy photos of Pluto have been taken by the Hubble Space Telescope, but astronomers will have to wait for a clearer view when NASA's New Horzons mission, which was launched on January 19, 2006, makes its closest approach on July 14, 2015. As an intereting aside, some of discoverer Clyde Tombaugh's ashes are aboard the New Horizon probe.
Again, all very interesting. Still, the point, spurred by the notation of the IAU's new definition of "planet" on this day five years ago, was to find out why Pluto is no longer considered a planet. Well, here's the thing. A resolution by the IAU said that in order to be a planet, an astronomical body must be in orbit around the Sun (or, I assume, a sun). It must be massive enough to be a sphere by its own gravitational force. And, it must have cleared the neighborhood around its orbit of other interplanetary debris. The third item in the definition is the sticking point where Pluto is concerned. It is slightly more complicated than that, but this is a history blog, not a science blog, all appearences to the contrary today.
As I mentioned up-post, at the same time that the IAU created its new definition of a planet, it also created a definition of dwarf planets, which is essentially the same thing as a planet, except that a dwarf planet has not cleared the neighborhood around its orbit of debris. And so that is what Pluto is considered to be now, a dwarf planet. This despite the fact that another of the four largest dwarf planets in the solar system, Haumea, which was named for the Hawaiian goddess of childbirth, is not spherical (item number one of the definition of a planet or a dwarf planet), but is shapred more like an American football. Which leads me to believe, if I might be allowed an opinion, that there is something wrong with the definitions.
Apparently, not even everyone in the astronomical community agrees that Pluto is not a planet. After a conference at Johns Hopkins University on August 14 - 16, 2008, a report was released stating that scientists could not come to a consensus regarding the definition of a planet. Well, they get to have an opinion, even if you and I don't, but there was also a certain amount of controversy among the public when Pluto was read out of the list of planets. I know, when I heard about it, my reaction was something like, "Hey, wait a minute..." And if asked how many planets there are, I still automatically answer, "Nine."
So, you see, you can attempt to find out about one particular event in history and end up learning about astronomy. Or geology, or mathematics, or biology, or politics, or construction, or business. Or, really, anything. And that is a good thing, I think. Certainly, I learned a few things I didn't know as I researched today's post.
I promise, this blog won't turn into Your Daily Science Lesson. But some things are just too interesting not to follow up on.
I started out with the idea that it would be a simple "On this day..." sort of exercise, but I've pretty much decided that the approach is a) too limiting of what I'm aiming to do and b) way too overdone.

The third item in the definition is the sticking point where Pluto is concerned. It is slightly more complicated than that, but this is a history blog, not a science blog, all appearences to the contrary today.
As I mentioned up-post, at the same time that the IAU created its new definition of a planet, it also created a definition of dwarf planets, which is essentially the same thing as a planet, except that a dwarf planet has not cleared the neighborhood around its orbit of debris. And so that is what Pluto is considered to be now, a dwarf planet. This despite the fact that another of the four largest dwarf planets in the solar system, Haumea, which was named for the Hawaiian goddess of childbirth, is not spherical (item number one of the definition of a planet or a dwarf planet), but is shapred more like an American football. Which leads me to believe, if I might be allowed an opinion, that there is something wrong with the definitions.
Apparently, not even everyone in the astronomical community agrees that Pluto is not a planet. After a conference at Johns Hopkins University on August 14 - 16, 2008, a report was released stating that scientists could not come to a consensus regarding the definition of a planet. Well, they get to have an opinion, even if you and I don't, but there was also a certain amount of controversy among the public when Pluto was read out of the list of planets. I know, when I heard about it, my reaction was something like, "Hey, wait a minute..." And if asked how many planets there are, I still automatically answer, "Nine."
So, you see, you can attempt to find out about one particular event in history and end up learning about astronomy. Or geology, or mathematics, or biology, or politics, or construction, or business. Or, really, anything. And that is a good thing, I think. Certainly, I learned a few things I didn't know as I researched today's post.
I promise, this blog won't turn into Your Daily Science Lesson. But some things are just too interesting not to follow up on.

When Dinosarus Walked the Earth (or something)...
Well, that's it. Another birthday come and nearly gone (I've still got an hour and eight minutes until it's over, as I write this).
I suppose I'm of an age when I should really stop celebrating my birthdays, or even acknowledging them. After all, as of today, I can officially order from the Senior menu at Denny's. And some people would probably tell me that I really need to start being secretive about my age, so better not to mention birthdays at all.
Rubbish.
I like birthdays, my own and other people's. Any excuse for a party is fine with me. Not that I had a party this year. Which is also fine. I did get a free lunch (again, at Denny's; did you know that if you go in on your birthday and show your ID to prove that it really is your birthday, you can get a free Grand Slam breakfast?). And I knitted with friends. And I got lots of birthday greetings on Facebook, greetings from at least three continents.
And I don't have a problem with admitting my age. (I'm 55 now, for those of you who don't know the Denny's menu.) I got here honestly, and it would be fairly stupid not to admit to it. It also means that I've seen a few things, and that I remember some things that are only history (maybe even ancient history) to younger generations.
So, you know, I don't mind saying that when I was born, Dwight Eisenhower was president, no one had been into outer space, and there were only 48 states. I saw Nikita Khrushchev's train when he visited the United States in the late 1950s. I heard tests of the rocket engines that took astronauts to the moon (the test facility was on a mountain across the valley from where I grew up). I remember the Cuban Missile Crisis and where I was when John F. Kennedy was assassinated.
And, damn it, I've earned every gray hair in my head.
So what if I'm now the age my grandmother was when I was born? I'm having much more fun, on the whole, that I ever did when I was in my 20s.

Maybe you can help me understand this...
So, I'm starting to re-read Lies My Teacher Told Me (Touchstone, 1995), by James W. Loewen. I mentioned it in a post a few days ago as covering some of the same territory as Michael Parenti's History as Mystery, only in a better, more interesting way.
In the Introduction, on page 15, Loewen writes, after discussing how boring history textbooks (and especially high school history textbooks) are and how often they aren't exactly accurate:
I knew that textbooks (of most kinds) are often not written by the named authors, but ghostwritten by publishing company employees. They're kind of like U.S. Supreme Court decisions that way; those are often written not by the Justice whose name is on the majority opinion, but by their law clerks. So that is not a shocking revelation to me.
However, I'm having a serious problem with his characterization of the attitude of many professional historians to the writing of textbooks. Why would they not want to participate in the writing of textbooks? Why would a professional not care whether or not the knowledge in their field is accurately presented to the next generation?
Maybe Loewen is exaggerating the problem? I don't know. I do know that the history textbooks I had in school, and that I've run across along the way are mostly very boring. I've never done a fact-check of any of them...although that would probably be an interesting project (yes, I'm a geek). But, despite the fact that whoever writes the books has to get a lot of information into a fairly small amount of space, I don't believe that history textbooks have to be boring and error-ridden. And certainly, even if the books are name/date/fact heavy, teachers can make the subject interesting. I've seen that done before. Not in my own junior high and high school classrooms, but that's another story for another time. It can be done.
What do you think? Can history textbooks be interesting and accurate? If Loewen is characterizing the attitude among professional historians toward the writing of textbooks accurately, do you think they need an attitude adjustment? How can that be accomplished? Do you think part of the problem lies at the hands of the textbooks publishers?
Oh, and one more question: If the minions are going to continue writing the textbooks, how do I get to be a minion? I think that would be a fun job to have. Well, maybe not if I have to do it in a basement, but still...I'm a writer, I love history, and I wouldn't have a problem with checking facts. I love to do research.
Edited to add: I do not mean to cast aspersions on the motives or attitudes of any professional historians by what I've written here. I'm asking these questions for a couple of reasons: 1) I don't know how accurate Loewen's characterizations are. 2) It is an issue that I'm concerned about as a writer; I want all books to be interesting, no matter what the subject, and I believe that they can be. I'm just here to learn.

Often a textbook is written not by the authors whose names grace its cover, but by minions deep in the bowels of the publisher's offices. When historians do write textbooks, they risk snickers from their colleagues--tinged with envy, but snickers nonetheless: "Why are you devoting time to pedagogy rather than original research?"

In which I finally manage to finish reading a book...
It took me a week, but I finally finished reading Michael Parenti's History as Mystery. I was nearly finished, but it took most of a week to make myself sit down and read the last ten pages or so, which are the end of a screed criticizing what he calls psychopolitics, the psychoanalysis of historical figures.
It isn't that I completely disagree with him on this, but it was also the part of the book where he explicitly (and finally) comes out as a Marxist historian, not my favorite way of analyzing history. As I said in an earlier post, it isn't because it's Marx, but that I find it a fairly simplistic way of looking at history. This is probably because I see a variety of things shaping historical events rather than just putting everything down to class conflict.
So, it was really funny to find Parenti, on page 265, calling psychopolitics "simplistic in its interpretation" and "reductionist", since that is pretty much how I view Marxist historical analysis. Just proves, to me anyway, that how you feel about historical analysis is relative, based on your own biases.
And, goodness knows, we all have our biases. I'm just more comfortable when a writer can recognize that they have biases and is willing to acknowledge them. My bias, then, related to my feelings about Parenti's book, is that, as I said, I don't like any analysis of history that reduce all causation to one single issue, such as class conflict. (Ouch! How many commas can I get into one sentence?) The world is a complicated place, motivations of the people who have shaped history are complicated, and to say that all of history comes down to any one aspect of all that is too simplistic for me.
Ah, well. It was an interesting book anyway, and Parenti has some interesting things to say. One of the most important things he writes about is the idea that "history", as it is viewed and taught in US public schools, is avoiding controversy and turning the student into a good citizen who does not question or criticize orthodox interpretations of How Things Should Be. This is not an original thesis, and has been explored by others, including Frances Fitzgerald in America Revised: History Schoolbooks in the Twentieth Century (Little, Brown: 1979) and James W. Loewen in Lies My Teacher Told Me: Everything Your American History Textbook Got Wrong (New Press: 1995). Both are very good books and do a better, more thorough job than Parenti does in looking at how US history is taught in US public schools. I recommend both books; in fact, I'm about to go back and re-read Loewen's book, and perhaps Fitzgerald's, as well.
Parenti, on the other hand, goes farther afield and his scattershot approach, while uncovering some interesting issues in history and historiography, is sometimes a bit difficult to follow and I would have liked it better if he had taken more time and care to tie all the threads here together into a more coherent whole. As it is, despite the valuable places he goes in the book, I was left wondering what his point was, aside from the fact that he advocates Marxist historical analysis.
Maybe that was he only point, in the end. He could have said that more clearly, rather than just tacking a one-page "afterward" to the last chapter, the one on psychopolitics, where he sort of just sticks his tongue out at orthodox history and historians and essentially proclaims that "My historical analysis can beat up your historical analysis."

I get these scathingly brilliant ideas sometimes...
And I intend to write about them, but then I get distracted by Ravelry or Facebook or Twitter, and before I know it, I'm about to fall asleep or its time to go to bed even if I'm not sleepy.
But I'm getting better. I managed to tear myself away from Ravelry (if you knit, crochet, spin, or dye, you might want to go visit) after only 45 minutes or so, and here I am. It's all in the willpower.
Yeah. Right.
Anyway...I'm still in the middle of my...well, it isn't a love/hate relationship, so just call it a like/throw it across the room relationship with History as Mystery. So, I'm not really prepared to write about it yet, but while I was reading at dinner tonight (at Irene's, home of the world's best hamburger and fries), I got what I can only call a scathingly brilliant idea.
I'm in the middle of chapter 5, in which Parenti writes about history and historians in academia. He complains (rightfully, to an extent) about the trouble leftist historians have had in the past in getting and keeping university appointments and points out that conservative (I think he really means rightist) historians have not had this problem, which is probably more true than not. But it struck me that he probably wouldn't be complaining if it was, say, Newt Gingerich, who lost his teaching post because of his ideology.
To be perfectly honest, I don't think that personal ideology belongs in the classroom. I've run up against that, on both ends of the political and ideological spectrum, and it just bothers me. However, there is no way that teachers, especially in history and political science, are going to check their beliefs at the door, so there needs to be another way to deal with how students are taught history.
Bingo. Right in the middle of munching a French fry, my scathingly brilliant idea sprouted. Because there needs to be room for left, center, and right (not the loony right, but real conservatives...and yes there is a difference, a big difference) on the university campus, there also needs to be a way to neutralize that for students. So, my idea is that, for history majors at least, to take their survey courses in U.S. (here in the States) and world history three times...once from a conservative professor, once from a centrist or moderate professor, and once from a leftist professor. At the same time...all three US history courses at the same time, and all three world history courses at the same time, so that they get all three perspectives in a way that can allow the students to compare and contrast and, oh, make up their own minds which is the most useful and accurate. Rather than be at the mercy of whichever point of view from whichever professor they happen to get because that course section fit into their schedule.
Yeah. I know. No university would ever go for that. I still think it is a brilliant idea. And I'm going to go on thinking so, because I don't get scathingly brilliant ideas very often.
So. I need to finish reading this book...I'm about three-quarters of the way through it. And I need to finish the other two books I'm reading, as well. The goal is to have Parenti finished before I head out of town Friday to go to my family reunion, seeing as it's due back at the library Monday anyway. Then, I'll take one or both of the others, if I haven't already finished them, with me in case I find some time to read in the evenings. But I'd like to have the fluff book finished before the weekend, as well. We'll see.
So, how was your day?
Oh, and extra points to anyone who can tell me what movie the concept of the "scathingly brilliant idea" came from.
