"Plurality should not be posited without necessity."  -- William of Occam

Ptolemaic


I added an extra hour to my commute this morning by taking a shortcut.  The pursuit of shortcuts is a common pastime in Atlanta -- and no doubt in most metropolitan areas.  My regular path to work involves taking the Ronald Reagan Highway to Interstate 85, and then the 85 to the 285 until I arrive at the northern perimeter.  Nothing could be simpler, and if it weren't for all the other cars, it would be a really wonderful drive.  But I can't help feeling that there is a better way to get to my destination, so I head off on my own through the royal road known as "surface streets".

Cautionary tales like Little Red Riding Hood should tell us all we need to know about taking the path less traveled, yet that has made no difference to me.   Secret routes along surface streets (shortcuts are always a secret of some kind) generally begin with finding a road that more or less turns the nose of one's car in the direction of one's job.  This doesn't last for long, however.  Instead one begins making various turns, right, left, right, left, in an asymptotic route toward one's destination. 

There are various rules regarding which turns to make, typically involving avoiding various well-known bottlenecks, such as schools and roadwork, avoiding lights, and of course avoiding left turns.  Colleagues and friends are always anxious to tell me about the secret routes they have discovered.  One drew me complex maps laying out the route she has been refining over the past year, with landmarks where she couldn't remember the street names, and general impressions about the neighborhoods she drove through when she couldn't recall any landmarks.  This happened to be the route that made me tardy this morning. 

When I told her what had happened to me, the colleague who had drawn me the map apologized for not telling me about a new side-route off of the main route she had recently found (yes, secret routes beget more secret routes) that would have shaved an additional three minutes off of my drive.  Surface streets are the Ptolemaic epicycles of the modern world.

A friend with whom I sometimes commute has a GPS navigation system on his dashboard, which changes the secret route depending on current road conditions.  This often leads us down narrow residential roads that no one else would dream of taking since they wouldn't know if the road leads to a dead-end or not -- but the GPS system knows, of course.  We are a bit slavish about following the advice of the GPS, even when it tells us to turn the trunk of the car toward work and the nose toward the horizon.  One time we drove along a goat path to Macon, Georgia on the advice of the GPS system in order to avoid an accident on S. North Peachtree Road Blvd. 

All this is made much more difficult, of course, due to the strange space-time characteristics of Atlanta which cause two right turns to always take you back to your starting point and two left turns to always dump you into the parking lot of either a Baptist church or a mall.

Various reasons are offered to explain why the Copernican model of the solar system came to replace the Ptolemaic model, including a growing resentment of the Aristotelian system championed by the Roman Catholic Church, resentment against the Roman Catholic Church itself, and a growing revolutionary humanism that wanted to see the Earth and its inhabitants in motion rather than static.  My favorite, however, is the notion that the principle of parsimony was the deciding factor, and that at a certain point people came to realize that the simplicity, rather than complexity, is the true hallmark of scientific explanation.

The Ptolemaic system, which places the earth at the center of the universe, with the Sun, planets and heavenly sphere revolving around it, was not able to explain the observed motions of the planets satisfactorily.  We know today was due to both having the wrong body placed in the center of the model, as well as insisting on the primacy of circular motion rather than elliptical route the planets actually take. 

In particular, Ptolemy was unable to explain the occasionally observed retrogression of the planets, during which these travelers appear to slow down and then go into reverse during their progression through the sky, without resorting to the artifice of epicycles, or mini circles, which the planets would follow even as they were also following their main circular routes through the sky.  Imagine a ferris wheel on which the chairs do more than hang on their fulcrums; they also do loop-de-loops as they move along with the main wheel.  In Ptolemy's system, not only would the planets travel along epicycles that traveled on the main planetary paths, but sometimes the epicycles would have their own epicycles, and these would beget additional epicycles.  In the end, Ptolemy required 40 epicycles to explain all the observed motions of the planets.

Copernicus sought to show that, even if his model did not necessarily exceed the accuracy of Ptolemy's system, he was nevertheless able to get rid of many of these epicycles simply by positing the Sun at the center of the universe rather than the Earth.  At that moment in history simplicity, rather than accuracy per se, became the guiding principle in science.  It is a principle with far reaching ramifications.  Rather than the complex systems of Aristotelian philosophy, with various qualifications and commentaries, the goal of science (in my simplified tale) became the pursuit of simple formulas that would capture the mysteries of the universe.  Whereas Galileo wrote that the book of the universe is written in mathematics, what he really meant is that it is written in a very condensed mathematics and is a very short book, brought down to a level that mere humans can at last contain in their finite minds.

The notion of simplicity is germane not only to astronomy, but also to design.  The success of Apple's IPod is due not to the many features it offers, but rather to the realization that what people want from their devices is only a small set of features done extremely well.  Simplicity is the manner in which we make notions acceptable and conformable to the human mind.  Why is it that one of the key techniques in legal argumentation is to take a complex notion and reframe it in a metaphor or catchphrase that will resonate with the jurists?  The phrase "If the glove doesn't fit, you must acquit" was, though bad poetry, rather excellent strategy.  "Separate but not equal" has resonated and guided the American conscience for fifty years.  Joe Camel, for whatever inexplicable reasons, has been shown to be an effective instrument of death.  The paths of the mind are myriad and dark.

Taking a fresh look at the surface streets I have been traveling along, I am beginning to suspect that they do not really save me all that much time.  And even if they do shave a few minutes off my drive, I'm not sure the intricacies of my Byzantine journey are worth all the trouble.  So tomorrow I will return to the safe path, the well known path -- along the Ronald Reagan, down the 85, across the top of the 285.  It is simplicity itself.

Yet I know that the draw of surface streets will continue to tug at me on a daily basis, and I fear that in a moment of weakness, while caught behind an SUV or big rig, I may veer off my intended path.  In order to increase the accuracy of his system, even Copernicus was led in the end to add epicycles, and epicycles upon epicycles, to his model of the universe, and by the last pages of On the Revolution of the Heavenly Bodies found himself juggling a total of 48 epicycles -- 8 more than Ptolemy had.

drinking_horn

There are various legends about drinking with the Immortals.  They typically involve a wanderer lost in the wilderness who is offered shelter by strange people.  He is brought close to the fire and given beer, or wine, or mead, depending on the provenance of the folktale.  As his clothes dry out, he is regaled by tales of ancient times and slowly comes to realize that his companions are not typical folk, but rather denizens from behind the veil.  He has fallen, through no merit of his own, into the midst of an enchanted world, and his deepest fear is not of the danger that is all around him, but rather that once the enchantment is disspelled, he will never be able to recover it again.

It occurred to me recently that I had such an experience about a year ago.  I was sent by my company to the Microsoft campus in Redmond to spend several days with the ASP.NET Team and other luminaries of the .NET world.

The names will mean nothing to most readers, but I had the opportunity to meet Bertrand LeRoy, Scott Guthrie, Eilon Lipton, and others to discuss the (then new) ASP.NET Ajax.  I had been painfully working through the technology for several months, and so found myself able to almost hold a conversation with these designers and developers.

On the final night of the event all the seminar attendees were taken to a local wine bar and had dinner.  As is my wont, I drank as much free wine as was poured into my glass, and began spinning computer yarns that became more and more disassociated from reality as the night wore on.  I'm sure I became rather boorish at some point, but the Microsoft developers listened politely, and in my own mind, of course, I was making brilliant conversation.

Even to those who know something of the people I was talking to, this might seem like no big deal.  I went drinking with colleagues in the same industry I am in -- so what.  But for me, it was as if I were suddenly introduced to the people who make the rain that nourishes my fields and the sunlight that warms my days.  Microsoft software simply appears as if by magic out of Redmond, and like millions of others, day in and day out, I dutifully learn and use the new technologies that come out of the software giant.  To find out that there are actually people who design the various tools I use, and build them, and debug them -- this is a bit difficult to conceive.

In A Room of One's Own, Virginia Woolf reflects on Charles Lamb's encounter with a dog-eared manuscript of one of Milton's poems, filled with lines scratched out and re-written, words selected and words discarded:

"Lamb then came to Oxbridge perhaps a hundred years ago. Certainly he wrote an essay-the name escapes me-about the manuscript of one of Milton's poems which he saw here. It was LYCIDAS perhaps, and Lamb wrote how it shocked him to think it possible that any word in LYCIDAS could have been different from what it is. To think of Milton changing the words in that poem seemed to him a sort of sacrilege."

My own discovery that the things of this world which I consider most solid and most real -- because they are so essential to my daily life -- could have been otherwise than they are, was a similar moment of shock, tinged with fear. 

In a moment of anxiety during this sweet symposium, I leaned over to the person immediately to my right and confided in him my strange reflections.  He laughed gently, and dismissed my drunken observations about the contingent nature of reality.  I later found out he was the twenty-three year old developer of the ASP.NET login control, used daily in web applications around the world, when he inquired of me whether I had ever used his control, and what I thought of it.

dystopia

dasBlog is the engine I have been using over the past year on my web site.  Besides its low cost (free as beer), and a tendency to be a reliable blog engine, I also like it because it uses XML files rather than a database to persist information.  The release version has been running on the .NET 1.1 Framework for quite a long while, and despite a teaser tag on their home site insisting that the new 2.0 version would be released in a matter of weeks, dasBlog 2.0 has actually taken a much, much, longer time to come out.

But now the wait is over, and I plan to upgrade to the newest version sometime later tonight.  As sometimes happens, this may entail the complete collapse of the site and the loss of all prior blog posts -- but I'm keeping my fingers crossed and maintaining a positive attitude about it, for such is the price of progress.

Supposing that I am successful in migrating to the newest version, I don't plan to post a review of the qualities of the new platform since, in this case, the medium is very much the message.

treefrog

Pronunciation: n-'kA
Function: adjective
Etymology: French, from past participle of manquer to lack, fail, from Italian mancare, from manco lacking, left-handed, from Latin, having a crippled hand, probably from manus
: short of or frustrated in the fulfillment of one's aspirations or talents -- used postpositively <a poet manqué>

-- Merriam-Webster Online

 

During my perusal of the August 27th New Yorker, I came across the word manqué in two different articles, which struck me as noteworthy as I don't think I have come across this word in several years.  A quick search of the New Yorker archives indicates that besides these two recent uses,  one in a snarky article about Nicolas Sarkozy by Adam Gopnik:

"People close to Sarkozy like to say that he is an American manqué...."

 and the other in a fawning review of Michelangelo Antonioni's film opus by Anthony Lane:

"This is not to say that the Italian was a novelist manqué."

the word had been used in an April review of a Richard Gere film, and prior to that had not appeared in the pages of The New Yorker since September of last year, in a short story by Henry Roth.

Occasionally an unusual word achieves a brief period of fashionability due to its rarity, such as was the case with the term disestablishmentarianism, and its dopplegänger anti-disestablishmentarianism, a few years back.  Once it is recognized that such a word has become le mot juste in just too many instances, however, it quickly recedes back into obscurity, like boy bands and one hit wonders. 

Playing with The New Yorker archives reveals similarly suggestive, if not definitive, phenomenological gold about the way rare words become popular for a brief time, and then go underground for a year or more.  Try, for instance, a search on sartorial, zeitgeist, or pusillanimous.  A more interesting project, of course, would involve sifting through the archives of several high-brow publications and graphing the frequency of rare words.  What a memetic field day that would be.

Perhaps this is peculiar to me, but I feel sometimes that using a given word more than once in a blue moon is already an overuse.  Such is my feeling about swearing, which should be used judiciously in order to achieve maximum impact, as well as my feeling about obscure words.  Obscure words, used judiciously, demonstrate erudition and good taste.  Rare words, when abused, simply demonstrate boorishness, false eloquence, and a supercilious character, as well as a proclivity toward intellectual bullying.  That's fucked up.

My sense that the obscure should be kept obscure does not pertain to words alone.  In the early 90's I came across an anecdote while watching Star Trek: Next Generation called the frog and the scorpion, which was ascribed to Aesop.  In the version I heard, a scorpion asks a frog to take him across a river and after much deliberation and rationalization, the frog finally agrees.  Unfortunately, the scorpion does decide to sting the frog midstream, after all, and when the frog asks why, the scorpion replies, "It is my nature."  The punchline is that they both drown.

Oddly I came across the same anecdote again, a few weeks later while watching Senator Robert Byrd of West Virginia deliver a speech on the Senate floor.  It probably was over an important international event, but I only remember the anecdote and no longer recall what the anecdote was meant to illustrate.  What was interesting about Senator Byrd's version is that he ascribed the story to Chaucer, rather than Aesop.

A while after that (was it months or years?) the anecdote came before me once again in another Star Trek franchise, Voyager, except this time it was described as a Native American myth and was told by the space-faring Indian Commander Chokote, and the protagonists were now a coyote and a scorpion rather than a frog and a scorpion.

A little research indicates that this particular anecdote may have originally been revived from its antique sleep in the movie The Crying Game, before it made its way through public policy papers, senate speeches, and finally into televised science fiction, where I came across it.

The first time I heard it, I found it charming. The second time, I thought it platitudinous.  The third time, I thought it was idiotic and vowed to boycott the next show, politician or foreign policy that attempted to leverage it in order to make a point.  Such is my nature.

Then again, I recall Benjamin Franklin's prescription that once one has found a word that works, it is unnecessary to go out of one's way to find synonyms in order simply to avoid overusing the word in a given piece of journalism or essay.  One should just reuse the word as often as one requires it -- which is common-sensical advice, I must admit.

9991

I've been stuck in a dilemma that many bloggers find themselves in.  I have been busy at work and can't find the time to write anything.  And I'm not the only one.  Look at Steve Yegge's blog.  He hasn't written anything in about a year.  Of course he has a huge readership and I have almost none -- which tempts me to just leave the blog fallow for a while. 

At the same time, what's the point of paying ten dollars a month if I don't say something?  As this thought occurs to me every few days, I start on the five or six ideas I have for a blog entry, but typically these ideas grow out of my control, and I find that I can't start talking about a movie I like without at least discussing Aristotle's Prime Mover, and I don't want to do that without mentioning Heiddeger's analysis of final and efficient causes in the Essay Concerning Technology, and so on and so forth...  Clearly, pretension is my Achilles heel.

Nevertheless, I need to write something, if only to get those fornicating monkeys off the top of my main page.

I considered posting an observational post, as many people do.  Just a few words about how I have been listening to such and such a song so what do you think about it please comment? -- but this seemed a bit too pathetic.

Next, I thought of resorting to what many bloggers do when they run out of ideas.  They post about how they aren't going to write anything for a while, which both informs readers of the situation and furtively counts as an actual post.

And then I came across this surfing blog, of which I am very fond for sundry reasons.  At this blog, the authors occasionally post about something they plan to write about but haven't yet found the gumption to actually pen.  Perhaps the convention has been around for a while, but I have not come across it before.  It's a brilliant notion.  So here goes ... my first "trailers" post.

Aristotle In Love -- in which the author contrasts the notion of efficient causes in ancient and modern times, as well as the way in which the ancient notion still exists in the attempt to find the cause of public works in private inspiration, and how this reveals an on-going concern with teleology and the metaphysics of essences -- with a side-discussion of contemporary cinema.

Zombies III -- in which the author attempts to extend his exploration of this cultural phenomenon from the perspective of privacy, with a further discussion of different notions of privacy over the centuries, revolving primarily around Kant's treatment of the subject in his political essay What is the Enlightenment?

Hillary's Knee -- in which the author discusses the films of Eric Rohmer and his own fascination with the inner life of one of the most public figures in American culture.

Catch Twenty-Two -- in which the author interweaves a discussion of war novels with the problem of threading deadlocks in software programming.  Hilarity ensues.

Why the Phantom of the Opera Is So Cool and The Cure is are Overrated -- in which the author writes about some of the music he has recently been listening to.
