Martha Nussbaum is one of my favorite philosophers; so is Colin McGinn. Both write brilliantly; both are often totally wrong; both are real people. Nussbaum runs marathons; McGinn body-surfs and plays video games. It goes without saying that I'm also a devout fan of Shakespeare. So when The New Republic recently offered a review ("Stages of Thought") by Nussbaum of three books on Shakespeare's philosophy, including one by McGinn ... well, who could resist?
But when I started reading I got stuck on the second paragraph, where another of my great addictions — lists — appears. Nussbaum, warming up her critical juices, raises three big hurdles:
To make any contribution worth caring about, a philosopher's study of Shakespeare should do three things. First and most centrally, it should really do philosophy, and not just allude to familiar philosophical ideas and positions. It should pursue tough questions and come up with something interesting and subtle — rather than just connecting Shakespeare to this or that idea from Philosophy 101. A philosopher reading Shakespeare should wonder, and ponder, in a genuinely philosophical way. Second, it should illuminate the world of the plays, attending closely enough to language and to texture that the interpretation changes the way we see the work, rather than just uses the work as grist for some argumentative mill. And finally, such a study should offer some account of why philosophical thinking needs to turn to Shakespeare's plays, or to works like them. Why must the philosopher care about these plays? Do they supply to thought something that a straightforward piece of philosophical prose cannot supply, and if so, what?
Alas, Nussbaum feels that McGinn falls short. Is she wrong? Append yet another book (Shakespeare's Philosophy: Discovering the Meaning Behind the Plays) to my far-too-long queue ...

Another small world encounter: several years ago my family was invited to dinner at our friends' home a half mile up the street. We originally met them ca. 1990 via my chance conversation with another patient parent at a childrens' chess tournament in downtown DC — I mentioned that we were seeking a piano teacher, and an opponent's mother told me about her kids' lessons. Although her family lived far away they were going to an instructor in my neighborhood. So began a relationship, first as piano/harpsichord students, later as friends, for the past two decades.
Anyway, also visiting our friends that evening was Peter Neumann, a semi-celebrity in the world of computer science. Peter is most known for the RISKS forum, an online publication/scrapbook concerning the risks of computers in society. But for us, or at least for me, his real claim to fame occurred before that dinner when my son Robin played some ragtime piano for the visitor. As seems to always happen with young performers, Robin was blasting out a Scott Joplin piece as fast as he could tickle the ivories, or rather, slightly faster than he could play it accurately. Neumann, a musician himself, stopped my son and told him that piano rags must be played slowly! Don't ask me why, but it stuck in my mind ...

The true origin of the word "blog": it's not an abbreviation of "web log" at all. Rather, it's simply a linguistically evolved version of the century-old word bloviate, meaning "to speak verbosely or windily"!
(many thanks to Angus Phillips (2007-11-26) whose use of "bloviating" in a recent essay and led me to this insight ... )

The 1999 movie Mystery Men (written by Bob Burden and Neil Cuthbert) is a clever, funny, well-made parody of the superhero genre that also stands alone. Among dozens of quotable lines that have become catchphrases around our household, some samples:
And, in reference to a squeeze toy that, sort of, defuses an escalating situation: "That little sucker just saved your life."

Donald Knuth, now 70 years old, is one of the founding fathers of modern computer science; his The Art of Computer Programming series somehow manages to combine rigor and readability, deep analysis and nerdy humor. I first picked up a volume of TAoCP in 1975 — literally picked it up, since I was at the time shelving books in the Rice University's Fondren Library to help pay for my undergraduate education. (cf. CollegeCollage2) Someone had taken it out of its place and left it on a table, and in the course of putting it back I read a wee bit of it, and was immediately hooked.
Son Merle recently sent me a link to an interview with Donald Knuth, conducted by Andrew Binstock for InformIT, an information technology educational publisher. It's a fascinating conversation that raises excellent questions about the current tidal wave of parallel computer architectures. It also reminded me of Knuth's "Literate Programming" philosophy, which Knuth declares to be one of the most important things he has done, as well as something of a failure. As he describes it:
Jon Bentley probably hit the nail on the head when he once was asked why literate programming hasn't taken the whole world by storm. He observed that a small percentage of the world's population is good at programming, and a small percentage is good at writing; apparently I am asking everybody to be in both subsets.
Donald Knuth's self-effacing modesty is also striking, as when he observes:
... Literate programming is what you need to rise above the ordinary level of achievement. But I don't believe in forcing ideas on anybody. If literate programming isn't your style, please forget it and do what you like. If nobody likes it but me, let it die.

Apollo 13 is an exceptional movie, full of nerdy heroism and high-tension problem-solving. Not long ago when I rewatched it one line suddenly caught my ear. An engineer praises another with the words, "You, Sir, are a steely-eyed missile man!" The term appears in the book that was the basis of the movie, Lost Moon: The Perilous Voyage of Apollo 13 by Jim Lovell and Jeffrey Kluger. From Chapter 6:
Anyone who had been working at the Manned Spacecraft Center for even a few weeks quickly learned that John Aaron was the stuff of folk songs. Among the men in the Canaveral blockhouse and the Houston control room, there was no greater tribute a controller could be paid than to describe him, in the rough poetry of the rocketry community, as a "steely-eyed missile man." There weren't many steely-eyed missile men in the NASA family. Von Braun was certainly one, Kraft was certainly one, Kranz was probably one too. John Aaron, a twenty-seven-year-old wunderkind from Oklahoma, had recently become one as well.
What delightful "rough poetry"!

"Pike's Peek" is a play on words. It's also an annual Sunday morning scamper down Rockville Pike, a major suburban Maryland street that on weekdays is clogged with automotive traffic. I ran it once, in 2002 (see Soggy Jog). This year on 27 April I'm a volunteer race official for the Montgomery County Road Runners Club that puts on the event. Before dawn I'm at the finish line, taking photographs and helping set up the fences and banners and chairs. Upon telephoned signal we start the big display clocks. Less than half an hour later the leaders appear, blasting out 10 km at a sub-5 minute/mile pace.
The trickle soon grows into a flood, and after a few thousand runners have passed I'm startled to see friend Mary Ewell appear in my camera's viewfinder. Soon after comes comrade Christine Caravoulias. After they've caught their breath we visit, chat, and make plans for future runs. At home I scan through more than a thousand photos and upload the majority of them to the MCRRC photo server. Most are of little interest except to the runners depicted in them; a few, however, catch my eye as having some small artistic merit. I must study them and see what happened right in those rare cases. The key element, I think is sharp focus — of the light on the sensor, and of the subject on the moment.

Good biographies let you peek into another person's life. The Color of Water: A Black Man's Tribute to His White Mother by James McBride (1996) is a good biography, full of love if not always rational, well-written if not always brilliant. McBride's mother was a deeply flawed person; some of what she did in raising her dozen kids could well be viewed today as child abuse. The family survived only via vast infusions of charity from family, friends, strangers, and society.
Chapter 8 ("Brothers and Sisters") offers a glimpse of their home. It begins:
Mommy's house was orchestrated chaos and as the eighth of twelve children, I was lost in the sauce, so to speak. I was neither the prettiest, nor the youngest, nor the brightest. In a house where there was little money and little food, your power was derived from who you could order around. I was what Mommy called a "Little Kid," one of five young'uns, microscopic dots on the power grid of the household, thus fit to be tied, tortured, tickled, tormented, ignored, and commanded to suffer all sorts of indignities at the hands of the "Big Kids," who didn't have to go to bed early, didn't believe in the tooth fairy, and were appointed denizens of power by Mommy, who of course wielded ultimate power.
My brothers and sisters were my best friends, but when it came to food, they were my enemies. There were so many of us we were constantly hungry, scavenging for food in the empty refrigerator and cabinets. We would hide food from one another, squirreling away a precious grilled cheese or fried bologna sandwich, but the hiding places were known to all and foraged by all and the precious commodity was usually discovered and devoured before it got cold. Entire plots were hatched around swiping food, complete with double-crossing, backstabbing, intrigue, outright robbery, and gobbled evidence. Back in the projects in Red Hook, before we moved to Queens, Mommy would disappear in the morning and return later with huge cans of peanut butter which some benevolent agency had distributed from some basement area in the housing projects. We'd gather around the cans, open them, and spoon up the peanut butter like soup, giggling as our mouths stuck closed with the gooey stuff. When Mommy left for work, we dipped white bread in syrup for lunch, or ate brown sugar raw out of the box, which was a good hunger killer. We had a toaster that shocked you every time you touched it; we called our toast shocktoast and we got shocked so much our hair stood on end like Buckwheat's. Ma often lamented the fact that she could not afford to buy us fruit, sometimes for weeks at a time, but we didn't mind. We spent every penny we had on junk food. "If you eat that stuff your teeth will drop out, " Mommy warned. We ignored her. "If you chew gum and swallow it, your behind will close up," she said. We listened and never swallowed gum. We learned to eat standing up, sitting down, lying down, and half asleep, because there were never enough places at the table for everyone to sit, and there was always a mad scramble for Ma's purse when she showed up at two A.M. from work. The cafeteria at Chase Manhattan Bank where she worked served dinner to the employees for free, so she would load up with bologna sandwiches, cheese, cakes, whatever she could pillage, and bring it home for the hordes to devour. If you were the first to grab the purse when she got home, you ate. If you missed it, well, sleep tight.
The food she brought from work was delicious, particularly when compared to the food she cooked. Mommy could not cook to save her life. Her grits tasted like sand and butter, with big lumps inside that caught in your teeth and stuck in your gums. Her pancakes had white goo and egg shells in them. Her stew would send my little brother Henry upstairs in disgust. "Prison stew," he'd sniff, coming back a few minutes later to help himself before the masses devoured it. She had little time to cook anyway. When she got home from work she was exhausted. We'd come downstairs in the morning to find her still dressed and fast asleep at the kitchen table, her head resting on the pages of someone's homework, a cold cup of coffee next to her sleeping head. Her housework rivaled her cooking. "I'm the worst housekeeper I've ever seen," she declared, and that was no lie. Our house looked like a hurricane hit it. Books, papers, shoes, football helmets, baseball bats, dolls, trucks, bicycles, musical instruments, lay everywhere and were used by everyone. All the boys slept in one room, girls slept in another but the labels "boys' room" and "girls' room" meant nothing. We snuck into each other's rooms by night to trade secrets, argue, commiserate, spy, and continue chess games and monopoly games that had begun days earlier. Four of us played the same clarinet, handing it off to one another in the hallway at school like halfbacks on a football field. Same with coats, hats, sneakers, clean socks, and gym uniforms. One washcloth was used by all. We all swore it belonged to us personally. ...
Ruth (Rachel Deborah) Shilsky McBride Jordan drove her children (at times violently) to become educated and self-reliant in a way that she herself never managed to achieve. James McBride credits her with the accomplishment, and mentions religion in a supporting rôle. The real engine of their success was, however, more likely the social welfare system — almost invisible in this book — that predominantly fed and housed and clothed and schooled her family. The success enjoyed now by the next generation of McBrides and Jordans speaks well for their mother, but it speaks better for the civilization that really brought them up.

A Gaussian, aka normal distribution or bell curve, is what most statistical averages converge toward. The "Square Root of N" rule-of-thumb says that if you toss 100 coins you'll get half heads, plus or minus 10 or so (since 10 = √100). Toss a million coins and you can expect half a million heads, plus or minus maybe 1,000 (= √1,000,000). Getting a little more precise: the standard deviation σ of N events, each of which is 50% likely, is half the square root of N. In general for probability p it's √(N * p * (1-p)).
How often does something happen more than a few standard deviations away from expectations? Worth remembering are the first few values: 68% of the time the result is within 1σ, 95% of the time it's within 2σ, and 99.7% of the time it's within 3σ. So for a thousand coins, or in a typical polling sample of a thousand evenly-split voters, about two-thirds of the time the result is within ~15 of the halfway point, 95% of the time it's within ~30 (= √N), and 99.7% of the time it's within ~45. The "Square Root of N" is thus a 95% guideline.
Beyond a few σ it's easier to look at how infrequently things happen — how often something occurs outside the window of that many sigma:
| σ | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|---|---|---|---|
| outside | 3 * 10-1 | 5 * 10-2 | 3 * 10-3 | 6 * 10-5 | 6 * 10-7 | 2 * 10-9 | 3 * 10-12 | 1 * 10-15 | 2 * 10-19 |
Events therefore fall within 3σ more than "two nines" (0.99+ of the time), 4σ more than "four nines" (0.9999+), 5σ more than "six nines" (0.999999+), and 6σ more than "eight nines" (0.99999999+). (Then the pattern in the exponents breaks down: rare events are even rarer than that.) Note also that "six sigma", a popular quality-control mantra in some industrial circles, isn't the usually cited value of 3.4 failures per million; it's more like a few chances per billion. But "4.5 sigma" doesn't have the alliterative ring to it that sells management advice books!

Most people are basically sane. For the majority of their lives, they support themselves and interact peacefully with others. Their beliefs track reasonably well with reality. They make a net positive contribution to society.
Or so I used to think; now I'm less sure. There are so many folks nowadays, it seems, who can't or won't take care of themselves, who break down when things don't go precisely as they wish, and who can't make a decision (and who won't admit that not-deciding is often a bad implicit decision).
But maybe it's not just a phenomenon of post-post-industrial civilization; maybe it has always been this way. The crazy cousin who lives in the attic ... the perpetual drifter ... the lazy kid who won't help in the fields, who wanders off rather than fetch water or participate in the hunt ....
My other optimistic belief in human nature remains solid: most people are basically good. At least, I hope so!

Earlier this week Joan Benoit Samuelson achieved a personal goal: she ran a marathon (the US Olympic Team trials) in under 2 hours 50 minutes after her 50th birthday. She says it may not be her last marathon, but it may be her last hard-run competitive one. Many years ago in her autobiography Running Tide she observed, in Chapter 8:
[Hitting the wall] taught me a lesson. Two lessons, in fact: you cannot go into a marathon unprepared, and anything can happen in such a long race.
The second lesson is one you learn at your peril, because once you're afraid of the marathon you have to develop ways of channeling the fear. I feel about marathons the way my parents taught me to feel about the ocean: it is a mighty thing and very beautiful, but don't underestimate its capacity to hurt you. ...
